I present for your information the following report for the fiscal year 1951 on the civil works activities of the Depart- ment of the Army which are carried out by the Corps of Engineers. 2. This report presents the engineering, statistical, and fiscal information regarding the authorized Federal improvements for navigation, flood control, and related water resource develop- ments, similar to that contained in previous annual reports of the Chief of Engineers. The Civil Works under the jurisdiction of the Corps of Engineers have, however, become a large and important segment of the over-all Federal civil works activities; and have attracted wide public interest. During 1950 and 1951 these activities have been given considerable study by Congres- sional Committees and by the President's Water Resource Policy Commission. Late in 1951 the Public Works Committee of the House of Representatives established a special Subcommittee to Study Civil Works. In response to the requirements of that Special Subcommittee I have prepared a comprehensive "Report on the Federal Civil Works Program as administered by the Corps of Engineers," which was transmitted to the special sub- committee on 27 March 1952. Since that report contains much information of value to the public generally I am including it as an additional volume to part I of this annual report. LEWIS A. PICK, Lieutenant General,-Chief of Engineers. 2 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 APPROPRIATIONS AND EXPENDITURES For use in the fiscal year 1951 net funds made available to the Corps of Engineers for river and harbor operations amounted to $187,190,164.05 and for flood-control operations $431,527,150.00, a total of $618,717,314.05. The expenditures from the available funds, including the balances on hand at the beginning of the fiscal year, amounted to $617,451,730.42, of which $192,761,364.22 was for river and harbor work and allied operations, and $424,- 690,366.20 for flood control and related work. New work was completed on 53 river and harbor and flood control projects, materially advanced on 137 other projects, and maintenance operations were in progress on 297 projects. The policy of the Corps of Engineers to have work performed by contract, except when the best interests of the United States require hired-labor operation, has been followed during the year, 79 percent of all work performed having been done by contract, and 21 percent by Government plant and hired labor. The continuation of an adequate check on the cost of work per- formed on river and harbor and flood-control projects has been maintained. Summary of these efforts is reflected throughout this report. With regard to the initiation of construction of new projects and the maintenance of existing projects, it is considered perti- nent to point out that the General. Appropriation Act, 1951 (Public Law 759, 81st Congress) provided for a reduction of over $75,000,000 in the Corps of Engineers' civil works construction program. It also called for an over-all reduction in Government expenditures for nondefense purposes of $550,000,000, a portion of which was applicable to the civil works program. In view of these reductions in funds and also the criteria set forth in the President's directive to all Government agencies to curtail nondefense expenditures, the Corps of Engineers' con- struction program for rivers and harbors and flood control was carefully screened to include only those projects which, as directed by the President, directly contribute to national defense or to civilian requirements essential in the changed international situation. Therefore, many worthwhile authorized river and harbor and flood control projects that could not be considered as meeting the requirements of the established criteria have been deferred for the duration of the present emergency. ACCIDENT PREVENTION During the fiscal year 1951 the application of comprehensive accident prevention to all new work operations and maintenance continued to hold accidental injuries to a low level. RIVERS AND HARBORS Program: The present-program for Federal improvement of rivers and harbors for navigation and allied purposes as author- ized by Congress includes projects located throughout the con- tineihtal United States, Puerto Rico, Alaska, and the Hawaiian RIVERS AND HARBORS Islands. The total estimated cost to complete all authorized river and harbor projects presently deemed necessary in the interest of commerce and navigation is about $4,394,328,300. Planning: New funds appropriated by the Civil Functions Appropriation Act, 1952, approved October 24, 1951, for advance planning for river and harbor projects total $500,000. These funds,_ together with unobligated balances, will be used to carry on the planning program during fiscal year 1952. Congress in appropriating planning funds for rivers and harbors specifically limited their use, in that no planning may be undertaken or con- tinued unless the individual project is certified by the President as necessary to the defense effort under criteria previously established. Navigation operations: Improvement operations were carried out on 54 river and harbor projects, of which 24 were com- pleted. Maintenance operations were performed on 297 projects, including the numerous coastal ports, harbors, and connecting channels on the Great Lakes, and the extensive Intracoastal Waterway and Mississippi River networks, together with the operation and care of the canalized Ohio River system, Illinois Waterway, the Upper Mississippi River, and the hydroelectric power plants on the Columbia River at Bonneville Dam, Oregon and Washington, and the Missouri River at Fort Peck Dam, Mont. In addition to the above-mentioned hydroelectric projects, many of the navigation dams that have been completed or are under construction have been authorized as multiple purpose projects in river and harbor legislation or, most recently, in omnibus bills covering both flood control and river and harbor projects. These multiple purpose projects have been designed to serve in the interest of navigation, flood control, and the production of hydro- electric power. In this connection, it may be noted that the authorizing legislation with respect to general project features, including local cooperation, reservoir management, recreation, disposal of power referred to in detail hereafter under Flood Control-General, is synonymous in many respects with river and harbor legislation for the authorization of multiple purpose navigation dams. It will be noted from the above that the Corps of Engineers' civil works construction program for the fiscal year 1951 was limited to those projects which would contribute directly to national defense or to essential civilian requirements as well as conserve the resources of men, materials, and equipment. In keeping with the reduction in funds and also the criteria set forth in the General Appropriation Act, 1951 (Public Law 759, 81st Congress), a review was made by the Bureau of the Budget of all projects which were eligible for appropriation under Public Law 759. The Bureau of the Budget approved the pro- gram as it complied in all aspects with Presidential and Con- gressional criteria directed by Congress. Under this curtailed construction program, work was continued throughout the fiscal year 1951 on 50 or more river and harbor REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 projects. The principal navigation projects under construction during the fiscal year, by states, follow: Demopolis Lock and Dam, Ala.; San Diego River and Mission Bay, Calif.; Jim Wood- ruff Lock and Dam, Ga. and Fla.; Chain of Rocks Laterial Canal, Ill.; Missouri River, Kansas City to Sioux City, Ia.; Cheatham Lock and Dam, Ky.; Gulf Intracoastal Waterway-Algiers cutoff; St. Marys River-powerhouse, Michigan; Mississippi River at St. Anthony Falls, Minn. and Keokuk Lock, Iowa; Newark Bay, Hackensack and Passaic Rivers, N. J.; New York and New Jersey Channels, N. J.; McNary Lock and Dam, Ore. and Wash.; Monongahela River, Locks 2, Pa. and W. Va.; Sabine-Neches Waterway, Tex.; and Chief Joseph Dam, Wash. COMMERCE The water-borne commerce of the United States, Puerto Rico, Alaska, and the Hawaiian Islands for the calendar year 1950 is contained in Part 2 of the Annual Report for the fiscal year 1951. PHILIPPINE PORT REHABILITATION Work was completed during the fiscal year 1951 on a $17,- 800,000 program for rehabilitation of port and harbor facilities in the Philippines under the authority contained in section 303 of the Philippine Rehabilitation Act of 1946, as amended by Public Law 295, Eighty-first Congress. WORK FOR OTHER AGENCIES Major dredging operations and construction of other fleet facilities were carried out during the year at various permanent reserve fleet sites for the United States Maritime Commission with funds transferred from that agency. Miscellaneous dredg- ing and related work was also performed for the Navy and other Government agencies on a reimbursement basis during the year. GENERAL FLOOD CONTROL The authorized general flood-control program, exclusive of the programs for the alluvial valley of the lower Mississippi River and the Sacramento River, Calif., is covered in this secton. The authorized programs for those two rivers are discussed in the two succeeding sections. Congress in the Flood Control Act approved June 22, 1936, established, and in the amendatory and supplemental general Flood Control Acts approved August 28, 1937, June 28, 1938, August 11, 1939, August 18, 1941, December 22, 1944, July 24, 1946, June 30, 1948, and May 17, 1950, reaffirmed the general policy that flood control throughout the United States is a proper activity of the Federal Government, in cooperation with the States and local communities, and that the Federal Govern- ment should improve or participate in the improvement of navi- gable waters or their tributaries for flood-control purposes, if such projects are economically justified and if the lives and social GENERAL FLOOD CONTROL security of people are otherwise adversely affected. Those acts also specified the local cooperation required for the projects authorized therein. These requirements of local cooperation, in brief, are as fol- lows: (a) Dam and reservoir projects authorized in any of the afore- mentioned flood-control or river and harbor acts are constructed entirely at the expense of the United States and are maintained and operated by the Corps of Engineers. No local cooperation is required for dam and reservoir projects unless specifically pre- scribed by special provisions of law. (b) For local flood-protection projects, except channel improve- ment or channel rectification projects authorized by the acts of 1936, 1937, and 1938, local interests must provide without cost to the United States all lands, easements, and rights-of-way neces- sary for the construction of the projects, hold and save the United States free from damages due to the construction works, and maintain and operate all the works after completion in accordance with regulations prescribed by the Secretary of the Army. Chan- nel improvement and channel rectification projects authorized by the acts of 1936, 1937, and 1938 are built at Federal expense, and no local cooperation is required. Exceptions to these general rules are provided by law in the case of certain specific projects. The Congress stated in the Flood Control Act approved Decem- ber 22, 1944, and reaffirmed in the acts approved July 24, 1946, and tJune 30, 1948, that in connection with the exercise of juris- diction over the rivers of the Nation through the construction of works of improvement for navigation or flood control, it is the policy of the Congress to recognize the interests and rights of the States in determining the development of the watersheds within their borders, and likewise their interests and rights in water utilization and control. In conformity with this policy Congress provided that plans, proposals, or reports of the Chief of Engi- neers for any works of improvement for navigation or flood con- trol not previously authorized, or authorized in the Flood Control Act of December 22, 1944, shall be submitted to the Congress only after these plans, proposals, or reports have been submitted to the governors of the States concerned, or such officials or agencies of the affected State, or States, as may be designated by the governors, and after coordination with the Secretary of the In- terior, if the drainage basin under investigation is located in a State lying wholly or in part west of the ninety-seventh meridian. Authority for the development of recreation facilities in con- nection with river and harbor and flood control reservoirs under the control of the Department of the Army is contained in the 1944 and 1946 Flood Control Acts which authorize the Chief of Engineers, under the supervision of the Secretary of the Army to construct, maintain, and operate public park and recrea- tional facilities in such reservoir areas and to permit the con- struction, maintenance, and operation of such facilities. The acts also authorize the Secretary of the Army to grant leases of lands, including structures or facilities thereon, in reservoir areas for REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 such periods and upon such terms as he may deem reasonable; and provide that the water areas of all such reservoirs shall be open to public use generally without charge for boating, swim- ming, bathing, fishing, and other recreational purposes, and ready access to and exit from such water areas along the shores of such reservoirs shall be maintained for general public use when such use is determined by the Secretary of the Army not to be contrary to the public interest. These acts further provide that no use of any such area shall be permitted which is incon- sistent with the laws for the protection of fish and game of the State in which the area is situated. The policy for the development of river and harbor and flood- control reservoirs to provide for the best possible utilization of the water resources of the Nation was broadened by the 1944 Flood Control Act, which states that whenever the Secretary of the Army determines upon recommendation by the Secretary of the Interior that any dam and reservoir project operated under the direction of the Secretary of the Army may be utilized for irrigation purposes, the Secretary of the Interior is authorized to construct, operate, and maintain under the provisions of the Federal reclamation laws such additional works in connection therewith as he may deem necessary for irrigation purposes. Such irrigation works may be undertaken only after a report and findings thereon have been made by the Secretary of the Interior as provided under reclamation laws and after subsequent specific authorization of the Congress (by an authorization act). A procedure for the disposal of electric power and energy generated at river and harbor and flood control reservoir projects under the control of the Department of the Army, and in the opinion of the Secretary of the Army not required in the opera- tion of such projects, was prescribed by the Congress in the Flood Control Act approved December 22, 1944. In accordance with this legislation such electric power and energy is to be delivered to the Secretary of the Interior, who shall transmit and dispose of this power and energy in such manner as to encourage the most widespread use thereof at the lowest possible rates to consumers consistent with sound business principles, the rate schedules to become effective upon confirmation and approval by the Federal Power Commission. The legislation states that preference in the sale of such power and energy shall be given to public bodies and cooperatives. Authority is contained in section 2 of the Flood Control Act of August 28, 1937, as amended, for the removal of accumulated snags and other debris and clearing and straightening the chan- nel in navigable streams and tributaries when, in the opinion of the Chief of Engineers, such work is advisable. The Flood Control Act of 1946 authorized allotment of $1,000,- 000 per year for the construction of emergency bank protection works to prevent flood damage to highways, bridge approaches, and public works when, in the opinion of the Chief of Engineers, such work is advisable. GENERAL FLOOD CONTROL 7 The Flood Control Act approved December 22, 1944, placed upon the Secretary of War the responsibility of prescribing regulations for the use of storage allocated for flood control or navigation at reservoirs constructed wholly or in part with Fed- eral funds. The Flood Control Act approved June 30, 1948, was in a sense an emergency bill, inasmuch as only projects presenting an emergency or acute condition were considered by the Congres- sional Committees on Public Works. That act contained several changes in existing law, as follows: (a) It provided authoriza- tion for the construction of small flood-control projects, subject to certain conditions of local cooperation, and economic justifica- tion, provided the cost of each project does not exceed $100,000, and placed a limitation of $2,000,000 per year on the total allot- ment for this type of remedial work for any one fiscal year; (b) Increased the scope of emergency repair authority contained in Section 12 of the Flood Control Act of July 24, 1946, by per- mitting the Corps of Engineers to perform certain necessary work beyond that required to restore the damaged structure to its original condition. The President on May 17, 1950, signed into law the first major omnibus river and harbor and flood-control act since 1946. This act, in addition to providing authority for the construction of numerous navigation projects throughout the Nation, authorized the initiation and continuation of all types of flood-control proj- ects ranging from small local protection works to comprehensive multiple-purpose developments for the control and conservation of the floodwaters of the great river basins, such as the Missis- sippi, Ohio, and Missouri. This act, known as Public Law 516, Eighty-first Congress, contains several changes in existing law as follows: (a) Provides authority for installation and mainte- nance of telephone service in dam tenders' dwellings at naviga- tion and flood-control dams; (b) Increases the emergency mone- tary fund provided for the repair and restoration of existing flood-control structures threatened or destroyed by floods from $2,000,000 to $15,000,000; (c) Increases the monetary fund provided for the construction of small flood-control projects not .specifically authorized by Congress from $2,000,000 to $3,000,000 for any one fiscal year with the provision that not more than $150,000 shall be allotted for this purpose at any single locality from the appropriation for any one fiscal year. Congress, in the Civil Functions Appropriation Act for 1952, approved 24 October 1951, made available funds in the amount of $316,544,100 for flood control, general, projects. This amount, together with all previously appropriated funds provided for by the Congress, totals $2,479,396,575, of which $2,356,600,175 was for the prosecution of the authorized flood control, general, projects, while the remaining $122,796,400 was for maintenance of completed projects, surveys, and minor items. In addition to these authorizations Congress has approved gen- eral comprehensive plans covering most of the important river basins of the country and including many additional projects for 8 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 flood control, hydroelectric power, and allied water uses. All of these projects are parts of comprehensive, coordinated plans for the river basins of the Nation to provide desirable and economic flood protection and allied benefits for a large number of centers of industry and population and for many thousands of acres of rich, agricultural land. A number of reservoirs in the authorized program also provide favorable possibilities for the economic de- velopment of large quantities of hydroelectric power. Several of the projects now authorized include power-generating machinery in the initial developments. Planning: New funds appropriated by the Civil Functions Appropriation Act, 1952, referred to above, included for advance planning for flood control, general a total of $1,000,000. These funds, coupled with unobligated balances, will be used to carry on the planning program during the fiscal year 1952. Congress specifically earmarked planning funds for three Kansas projects Tuttle Creek, Strawn, and Toronto Reservoirs. In addition to these three projects planning may be undertaken or continued on such additional projects as may be certified by the President as necessary to the defense effort under criteria previously estab- lished. At the close of the fiscal year, a total of 330 flood-control, general, projects were either completed and in operation or con- struction was sufficiently advanced to permit partial operation. Of this total, 19 projects were placed in operation during the fiscal year ending 30 June 1951. At the same time, construction work was continued on 83 projects. During the year, construc- tion work was initiated on 2 reservoirs. Reservoirs placed in operation during the fiscal year included the Benbrook Reservoir, Tex.; the Fort Gibson Reservoir, Okla.; the Bull Shoals Reservoir, Ark.; the Hulah Reservoir, Okla.; the Farmington Reservoir, Calif.; and the Baldhill and Homme Reservoirs in North Dakota. Local protection projects placed in operation during the fiscal year included units of the Central and Southern Florida project; the projects at Macon, Ga.; Olean, N. Y.; Sunbury, Pa.; Covington, Ky.; Bartley, Nebr.; Polecat Creek, Okla.; Galena, Ill.; the project at Red Lake and Clear- water River, Minn.; the Wood River Drainage and Levee District, Illinois; the Chouteau, Nameoki, and Venice Drainage and Levee District; and the project in the vicinity of Nehalem, Oreg. Although protection of life and property is ever on the in- crease due to the construction and operation of Corps of Engi- neers flood control structures, the threat of floods still exists. In this respect it is pertinent to mention that floods occurred in many of the river basins throughout the Nation during the fiscal year 1951, some of which are described in the following para- graphs. During the months of May, June, and July, general rains and a series of storms occurred throughout many sections of the Kansas River Basin. As a result, practically all the streams in this basin overflowed their banks. The great flood of 1951 reached its climax during the period of 11-14 July, inundating a SACRAMENTO RIVER FLOOD CONTROL total of 186 cities and towns in the Kansas and Osage River Basins and along the lower Missouri River from Kansas City to the mouth. Approximately 87,000 persons were forced to leave their homes because of high water conditions. Many thou- sands of dwellings were inundated and more than 2,500 were totally destroyed. The lives of 28 persons are known to have been lost as a direct result of the flood. The largest and by far the most completely devastated area was along the main stem of the Kansas River where floods exceeding all previously known records swept downstream, inundating such cities as Manhattan, Topeka, Lawrence, and finally the Kansas Citys located at the confluence of the Kansas and Missouri Rivers. Total damages throughout the basin exceed $870,000,000. The existing Federal flood-control projects in the basin that were in operation during the flood prevented damages in excess of $272,000,000. If the authorized and proposed flood-control works in this basin had been in operation during the period of flooding, marked reduc- tions in flood heights would have been attained, resulting in the protection of hundreds of thousands of acres of farm land and many cities. Floods occurred in many other river basins throughout the Nation during fiscal year 1951, including the Susquehanna, Sacra- mento-San Joaquin, Minnesota, Cumberland, and Willamette River Basins. Although damages in many of these basins were considerable, they nevertheless were greatly reduced by flood- control projects constructed by the Corps of Engineers. SACRAMENTO RIVER FLOOD CONTROL The authorized project for the control of floods and other pur- poses on the Sacramento River, Calif., as adopted by the Flood Control Acts approved March 1, 1917, May 15, 1928, August 26, 1937, and August 18, 1941, provides for the enlargement of river channels, the excavation of cut-offs, the construction of levees, weirs, bank protection, and pumping facilities in the lower Sacramento River Valley and for channel clearing, rectification and snagging on the Sacramento River and tributaries in Tehama County, and from Red Bluff southerly. The total estimated Fed- eral cost of the project is $61,060,000. Up to the present time Federal funds in the amount of $42,811,500 have been appropri- ated by Congress for the prosecution of this project, including $1,000,000 provided for in the Department of the Army Civil Appropriations Act, 1952, approved October 24, 1951. Local inter- ests have expended funds in excess of $52,000,000 on this project including a cash contribution of approximately $6,761,700 for construction by the Corps of Engineers of protective works re- lated to the authorized project. In addition to this existing project, Congress in" the Flood Con- trol Act approved December 22, 1944, as a part of the general flood-control program, authorized the modification of the existing project for the Sacramento River to provide for certain changes and extensions in levees and other structures, and for the con- 10 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 struction of nine local levee and channel improvements, the Black Butte Dam and Reservoir and the low Table Mountain Dam and Reservoir with power facilities, substantially in accordance with the recommendations of the Chief of Engineers in House Docu- ment Numbered 649, Seventy-eighth Congress, second session. The estimated Federal cost revised in 1951 is $111,140,000. The project works of the Sacramento flood-control project pro- vide protection to cities and towns, to thousands of acres of agri- cultural lands, and to railway and highway networks of great importance to the civilian economy of the western part of the United States. Work accomplished during the year included the construction of levees along flood channels, including reinforcement of uncom- pleted levees, clearing brush and removing snags and incidental work on roads and irrigation facilities. Advance planning in- cluding preparation of detailed plans and contract plans was continued. MISSISSIPPI RIVER FLOOD CONTROL Progress was made during the fiscal year 1951 on the flood- control project for the alluvial valley of the Mississippi River, adopted by the Flood Control Act approved May 15, 1928, and amended by the acts approved June 15, 1936, June 28, 1938, Au- gust 18, 1941, December 22, 1944, July 24, 1946, June 30, 1948, and May 17, 1950. The 1936 amendment retained the purpose of the 1928 act and the features completed under that authority, and authorized an additional $272,000,000 for extension of flood- control work on the lower Mississippi River. The 1938 amend- ment removed legislative restrictions with respect to certain features of the amended plan and authorized $40,000,000 for work in addition to that contemplated for the project as amended in 1936. The 1941 amendment provided for the abandonment of the Boeuf and Eudora floodways and extension, and for raising main Mississippi River levees to confine within those levee lines be- tween the mouths of the Arkansas and Red Rivers the project flood without a floodway west of the Mississippi River. That amendment also authorized certain minor modifications and back- water protection in the Yazoo and Red River backwater areas at an estimated additional cost of $25,982,000. The 1944 amend- ment modified the existing project to provide for a navigation channel 12 feet deep and 300 feet wide at low water between Cairo, Ill., and Baton Rouge, La., by the execution of a channel improvement and stabilization program at an estimated cost of $200,000,000 and also modified the project for flood protection in the backwater area of the Yazoo River to include additional work at an estimated cost of $1,952,000. The 1946 amendment increased the project authorization by $161,675,500 to provide for several new items of related work; for incorporating in the alluvial valley project items of work that had been previously adopted under "Flood control, general" legislation but that were physically located within the alluvial valley and should be a part of the comprehensive project; and for the increased cost MISSISSIPPI RIVER FLOOD CONTROL 11 of construction of the unfinished features of the comprehensive project. The 1948 amendment modified the project to provide for the improvement of the Mississippi River with respect to the West-Tennessee tributaries; the improvement of the L'Anguille River, Ark.; and the Devils Swamp project at Baton Rouge, La. The Flood Control Act of 1950 increased the authorization for the Red River backwater area from $14,000,000 to $29,000,000; authorized flood-control and major drainage improvement in the St. Francis River Basin at a partial cost of $20,000,000; modified the 1946 Flood Control Act with respect to local cooperation; authorized the plan for flood protection in the Cache River Basin at a partial cost of $10,000,000; amended the 1928 Flood Control Act to include flood-control improvements in the Parish of Or- leans, La..;' authorized the filling of Grant's Canal at Lake Provi- dence, La., at a cost of $11,000 ; authorized flood protection for Des Arc, Ark., at a cost of $228,000; authorized the project for Lake Pontchartrain, La., at a cost of $3,150,000; authorized the project for emergency bank protection on the Amite River at a cost of $50,000; authorized the project for Grand Prairie Region and Bayou Meto Basin at a partial cost of $6,000,000 and, in addition to the above items, the Lower Mississippi River project was increased by an additional $200,000,000. The total authori- zation for the project as amended and supplemented is now $1,292,748,500, of which $769,466,223 has been appropriated through fiscal year 1952. In accordance with the provision of the act approved August 18, 1941, "that funds hereafter expended for maintenance shall not be considered as reducing present remaining balances of authorizations," it is estimated that $138,541,601 expended for maintenance since August 18, 1941, or scheduled for expenditure during fiscal year 1952, will not be deducted from the total authorizations for the project. Satisfactory progress was made during the year on principal features of the project on the main river, on the tributaries, and in the side basins. Main-stem work on levees, revetments, Memphis Harbor, and the Morganza Control Structure was con- tinued within the limit of available funds. In the Atchafalaya Basin, work was accelerated to provide the essential features necessary in the event of a major flood. The N. O. T. and M. U. S. Highway 190 and the T. & P. Main Line High-Level Crossings in the Morganza Floodway are complete. Bayou Sorrell Lock and Berwick Lock are complete. Work was started on the Bayou Boeuf Lock at Morgan City. Wax Lake Outlet and Charenton Canal are complete. In the Yazoo Basin, Sardis and Arkabutla Reservoirs are complete, Enid Reservoir is essentially complete, and work was accelerated on Grenada, the remaining reservoir to be completed. Work was continued on other features in the project for which appropriations were available. Under section 6 of the 1928 act, flood-control work was under- taken on the Mississippi River between Rock Island, Ill., and Cape Girardeau, Mo., and on outlets and tributaries affected by back- 12 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 waters on the Mississippi River, wherever the local contributions of one-third of the costs were provided as required by law. The Department was able to assist localities in the emergency repair of flood-control works on tributaries of the Mississippi River threatened or destroyed by flood, under the provisions of section 9 of the act approved June 15, 1936. Work accomplished on the adopted project for the alluvial valley of the Mississippi River has demonstrated its effectiveness by affording protection from general overflow for a period of more than twenty years to date. However, because of the elimina- tion of the Eudora floodway by the Flood 'Control Act of 1941, the levee system which constitutes the major part of the project is not yet sufficiently complete to afford protection against pre- dicted floods. Even a partial overflow of the valley may interrupt postal service, transcontinental and interstate commerce, and produce widespread destruction and disorder, national in scope. As flood control of this vast alluvial valley and navigation of the lower Mississippi River are important to the national economy and to the security of a large number of people, this project should be steadily prosecuted toward completion. SURVEYS During the year reports in response to 111 items of law en- acted by Congress and resolutions adopted. by Congressional committees authorizing investigations of the advisability of potential river and harbor and flood-control improvements were completed and transmitted to Congress with the recommenda- tions of the Chief of Engineers. Of these investigations, 37 were preliminary examinations and 22 were surveys made in reponse to authority contained in river and harbor and flood-control acts, and 52 were reexaminations undertaken pursuant to committee resolutions. Ten of the above reexaminations were limited to preliminary examination scope and were transmitted to the Committee on Public Works of the House of Representatives for authority to submit a report of survey scope. In addition, the Chief of Engineers completed reports on four cooperative beach erosion control studies and transmitted one interim survey report to Congress. The Public Works Committees of Congress adopted 83 resolu- tions requesting review of prior reports on proposed river and harbor and flood control improvements. Pursuant to section 205 of the Flood Control Act approved May 17, 1950, the President's directive to the Secretary, Depart- of the Army, dated October 9, 1950, and resolution adopted by the Federal Inter-Agency River Basin Committee on October 27, 1950, the New England-New York Inter-Agency Committee was formed to survey the resources and related matters of the New England-New York region. Membership consists of one representative each of the Department of Agriculture, Depart- ment of the Army, Department of Commerce, Department of the Interior, the Federal Power Commission, and the Federal Secur- ity Agency, with the Department of the Army the Chairman SURVEYS 13 agency. The survey is being conducted in cooperation with the Governors of the seven States participating in the survey. Sche- duled completion date for the survey report is June 30, 1954. Information and data is being obtained through the field offices of the Federal agencies and the departments of the seven States, supplemented by public hearings held throughout the region. Periodic joint conferences are held with the Governors to co- ordinate Federal and State activities. Public hearings have been held in Springfield, Mass. (27 June 1951) and Syracuse, N. Y. (16 October 1951). The cost of work during the fiscal year amounted to $366,557.82 and expenditures $308,975.97. Unex- pended balance of $326,024.03 together with an anticipated allot- ment of $400,000, a total of $726,024.03, will be applied as needed during fiscal year 1952 to payment of expenses incurred under this heading. For itemized reports, see reports of the New England Division and the New York and Buffalo Districts. A comprehensive investigation for flood control and allied purposes in the Arkansas, White, and Red River Basins, Arkan- sas, Louisiana, Oklahoma, Texas, New Mexico, Colorado, Kansas, and Missouri was authorized by the Flood Control Act of 1950. Pursuant to this legislation, the President of the United States in his letter of 19 May 1950 to the Secretaries of the interested Federal agencies requested that they organize an inter-agency committee, formulate procedure, and map out a joint plan of investigation, indicating specifically the precise responsibilities of each and the prospective allocation of agency resources to the joint effort. In conformance with the authorizing act and the President's letter, the Arkansas, White, Red River Basins Inter- Agency Committee was organized with one member each from the Department of the Army, Department of the Interior, De- partment of Agriculture, Department of Commerce, Federal Power Commission, and the Federal Security Agency. The Divi- sion Engineer, Southwestern Division, who represents the De- partment of the Army, was designated chairman of the Committee. The Governor of each of the eight States concerned, or his representative, has participated in the regular meetings of the Committee. During the year, thirteen regional and four basin- wide public hearings were conducted; organization and proce- dures to facilitate preparation of the report were formulated; an inventory of the desires of local interests and an analysis of resources and economic development related to the major sub- jects to be reported upon were essentially completed. Expendi- tures on the report by the Corps of Engineers as of 30 June 1951 were $753,033.21. The report is scheduled to be completed by 30 June 1954. Pursuant to section 1 of the Flood Control Act approved on December 22, 1944, section 1 of the River and Harbor Act ap- proved on March 2, 1945, and agreement of the Federal Inter- Agency River Basin Committee all authorized investigations by the Corps of Engineers of works of improvement for navigation, flood control, and related purposes were coordinated with the requisite State and Federal agencies. 14 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The gathering of hydrological data in Nicaragua, under authority contained in the River and Harbor Act approved on June 20, 1938, was continued. The cooperative programs with the United States Weather Bureau and the Geological Survey for the purpose of more ade- quately meeting the requirements of the Department in the plan- ning and operation of flood-control and river and harbor improve- ments were continued. Projects included in the cooperation with the Weather Bureau were: (a) operation of a Nation-wide net- work of recording rain gages; (b) hydrometeorological investiga- tions and review of the studies of major storms of record, the preparation of estimates of maximum possible precipitation for selected drainage basins, and preparation of generalized estimates of maximum possible precipitation over the United States east of the 105th meridian for areas of 10, 200, and 500 square miles and selected durations; (c) operation of cooperative networks of reporting rainfall and river stations; (d) program for the pre- paration of 48-hour quantitative forecasts of storm rainfall to facilitate the operation of reservoirs and local flood-protection projects; and (e) program of snow-melt investigations to evalu- ate all: important factors contributing to floods caused primarily by snow-melt. Cooperation with the Geological Survey involved primarily the installation, operation, and maintenance of stream- gaging stations for obtaining records of stream flow. The devel- opment of certain equipment for general stream gaging was continued. SURVEYS FOR NAVIGATION, FLOOD CONTROL, POWER, AND IRRIGATION Existing project. The existing project provides for making investigations of those navigable streams and their tributaries whereon power development appears feasible and practicable, with a view to the formulation of general plans for the most effective improvement of such streams for the purposes of navi- gation and the prosecution of such improvement in combination with the most efficient development of the potential water power, the control of floods and the needs of irrigation. The River and Harbor Act of January 21, 1927, adopted the project as laid down in House Document 308, Sixty-ninth Con- gress, first session, and added the following streams to those listed in that document: Red River, Yazoo River and tributaries, Pearl River, Altamaha River and tributaries, tributaries of the Warrior, Coosa, and Tombigbee Rivers. The Flood Control Act approved May 15, 1928, extended the scope of the investigation and surveys so as to include tributaries of the Mississippi River system, subject to destructive floods, and laid down certain addi- tional investigations on these tributaries. Further study or review of reports is authorized by section 6 of the River and Harbor Act of August 30, 1935, reading as fol- lows: That the Surveys authorized pursuant to section 1 of the River and Harbor Act of January 21, 1927, and House Document No. 308, Sixty-ninth Congress, first session, shall be supplemented by such additional study or investigation as the Chief of Engineers finds necessary to take into account important changes in economic factors as they occur, and additional stream- flow records: or other factual data. Operations and results. Work on each of the surveys involved was inaugurated in the spring of 1928. Valuable cooperation has been received from other Federal agencies; from State, county, and municipal engineers; from levee and drainage districts, hydro- electric companies, railroads, universities, and other local sources of information. Stream-gaging stations, where needed, have been established mainly in cooperation with the United States Geo- logical Survey. At the close of the fiscal year 1949, surveys of 191 streams had been completed and reports thereon transmitted to Congress, and reports on the remaining streams well ad- vanced to completion. For list of reports transmitted to Congress, see Annual Report for 1938, pages 1953-1957. In addition, four reports have been transmitted to Congress as follows: Transmitted Name of stream to Congress Printed in document No. Mississippi River above mouth of the Ohio River-..-.---- Mar. 16, 1940 H. 669, 76th Cong., 3d sess.

This river drains a large number of lakes and small streams in north central and eastern Maine and, after assuming definite character as a stream, flows about 100 miles in a south- erly direction through the middle of the State, discharging into Penobscot Bay, about 90 miles northeast of Portland, Maine. (See U. S. Coast and Geodetic Survey Chart No. 311.) Previous projects. Adopted by the River and Harbor Act of July 11, 1870, and modified by the River and Harbor Acts of March 3, 1899, and July 11, 1947. Estimated cost of previous projects corrected in 1949. Work accomplished under act of August 14, 1876 and prior acts $198,300. The estimated cost of work accomplished in Kenduskeag Stream, declared to be non- navigable by special act of July 11, 1947, $10,700. Total cost of previous projects, $209,000. For further details of previous projects, see page 1732 of Annual Report for 1915, page 48 of Annual Report for 1938, and page 31 of Annual Report for 1949. Existing project. This provides for dredging to a depth of 22 feet between Winterport and Bucksport, about 16 miles below Bangor; for straightening, widening, and deepening to 15 feet the channel near Stearns Mill and near 'Crosbys Narrows from 3 to 4.5 miles below Bangor; and for deepening the harbor at Bangor to 14 feet and widening it along the Bangor front, giving RIVERS AND HARBORS-NEW ENGLAND DIVISION 27 an additional width of from 100 to 300 feet for a length of about 2,000 feet. The project depths refer to mean low water, which is 3 feet above extreme low tide. The mean range of tide at Bangor is 13.1 feet, and the extreme about 15 feet. The cost for new work for the completed project was $292,- 020.53 exclusive of amounts expended under previous projects. The latest (1950) approved estimate for annual cost of mainte- nance is $3,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents July 5, 1884 Widening the channel at Bangor and Crosby sNar- S. Ex.

Local cooperation. None required. Terminal facilities. The river front of Bangor has 12 wharves, most of which are of the timber-crib stone-ballasted type. Exten- sive improvements and alterations are in progress at all the oil terminals to handle increase receipts of petroleum products. Eleven of the wharves have physical connection with a railroad. On the east side of the river at Brewer, opposite Bangor, there is one water terminal, a coal-handling plant having mechanical appliances and three petroleum products storage plants. The re- mainder of the terminals on the east side of the river are in poor condition. At South Brewer there is a large pulp and paper plant which has water connections, oil-pumping and storage facilities. There are a number of private wharves open to the public at mod- erate charges. At Bucksport on the north side of the river there are three important terminals, one a coal-handling plant and two used by a large paper manufacturing plant which has terminal facilities for the receipt and storage of oil products and pulpwood. The terminal facilities are considered adequate for existing needs. Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project was com- pleted in 1913. The controlling depths at mean low water were about 14 feet from Bucksport to Winterport; channel opposite Lawrence Cove about 14 feet (1947) ; channel at Frankfort Flats, 21 feet (1947) ; thence 15 feet to Stearns Mill; thence 14 feet to Bangor, except for a shoal area in Bangor Harbor on the Brewer side, where the least depth is 4.6 feet (1937). The costs and expenditures under the existing project have been $386,244.10, of which $292,020.53 was for new work and $94,223.57 was for maintenance. Proposed operations. No work is scheduled for the fiscal year 1952. 28 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The sum of $55,000 can be profitably expended during the fiscal year 1953 for maintenance dredging, by United States hopper dredge, in restoring the project depths in the channel opposite Lawrence Cove and in the vicinity of Frankfort Flats.

KENNEBEC RIVER, MAINE Location. Kennebec River drains a large number of lakes and minor streams, and flows from Moosehead Lake about 150 miles in a southerly direction and discharges into the Atlantic Ocean about 25 miles east of Portland. (See U. S. Coast and Geodetic Survey Charts Nos. 288, 289, and 314.) Previous projects. The first project was adopted by the River and Harbor Act of March 2, 1827. Modifications and additions were authorized by River and Harbor Acts of August 30, 1852, June 23, 1866, July 11, 1870, March 3, 1871, March 3, 1873, March 3, 1881, and August 11, 1888. For further details of previous projects see page 1735 of Annual Report for 1915, and page 52 of Annual Report for 1938. Existing project. This provides for a channel 27 feet deep and not less than 500 feet wide, extending from the mouth to a point about 0.6 mile above the bridge at Bath; thence to Gardiner a channel not: less than 150 feet wide, with a depth of 17 feet at Beef Rock Shoal, at the foot of Swan Island, 18 feet deep through rock at Lovejoy Narrows, near the head of Swan Island, decreas- ing to 16 feet deep at Gardiner; a channel west of Swan Island 100 feet wide, 12 feet deep, except at the upper shoal, where the depth was to be 15 feet; and a channel 125 feet wide and 11 feet deep from Gardiner upstream to Augusta, at the head of naviga- tion. The section of river included in the project is about 44 miles in length. The work includes dredging, rock excavation, and two riprap training walls. The project depths refer to mean low water. The mean tidal range is 8.3 feet at the mouth of the river, 6.5 feet at Bath, 5.5 feet at the foot of Swan Island, 5 feet at Gardiner, and 4.1 feet at Augusta. The spring tides are about 1 foot greater at the mouth and about 0.5 foot greater at Augusta. The estimate of cost for new work, approved in 1951, is $194,- 500, exclusive of amounts expended under previous projects. The latest (1950) estimate for annual cost of maintenance is $8,000.

In House Document No. 2107, Sixty-fourth Congress, second session, it was recom- mended that the improvement and maintenance of the channel west of Swan Island, near the town of Richmond, be abandoned. Local cooperation. None required. Terminal facilities. Wharves suitable for landing or loading are located at Bath, Woolwich, Richmond, Randolph, Gardiner, Hallowell, and Augusta. Of the 24 wharves located at Bath, 5 are publicly owned and 19 privately owned, about one-third of which are in poor repair and are little used. Rail connections are avail- able at 19 of the wharves at Bath. Depths alongside range from 12 to 25 feet. At the other points named above there are 16 wharves in usable condition. All but one are equipped with mech- anism for handling passengers and freight. Those open to the public on equal terms are two at Hallowell and one each at Randolph and Augusta. None is publicly owned. Extensive altera- tions and new construction are contemplated at Augusta to handle coal receipts. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance dredg- ing, by U. S. Hopper Dredge Lyman, was commenced on Novem- ber 1, 1950, and was completed on November 15, 1950. During this period 108,830 cubic yards of sand were removed at a cost of $27,546.68. The expenditures were $27,546.68. Condition at end of fiscal year. The existing project was com- pleted December 1943, with the exception of project dredging from the Bath Iron Works Corporation to its upper limit 0.6 mile above the Bath Bridge, for which there appears to be no im- mediate need. The controlling depths at mean low water in the Kennebec River from the mouth to Bath are 25.0 feet (1950), with the exception of a shoal area along the northerly limit of the channel northwest of North Sugarloaf Island, having a controlling depth of 21.0 feet (January 1951); 13 feet from Abagadasset Point to the Gardiner-Randolph Bridge (1942); thence 8 feet to Augusta for the project channel widths (1942). The costs and expenditures under the existing project have been $1,303,693.81, of which $1,090,529.30 was for new work and $213,164.51 was for maintenance. Proposed operations. The funds unexpended June 30, 1951, amounting to $2,453.32 will be used for a condition survey, by hired labor, in the spring of 1952. No work is scheduled for fiscal year 1953. 30 REPORT OF CHIEF OF ENGINEERS, U. S.

KENNEBUNK RIVER, MAINE Location. The source of Kennebunk River is in the central part of York County in southwestern Maine. The stream flows about 15 miles in a southeasterly direction and discharges into the Atlantic Ocean about 30 miles southwest of Portland, Maine. (See U. S. Coast and Geodetic Survey Chart No. 1205.) Existing project. This provides for the construction of a stone breakwater on the easterly side of the mouth of the river about 550 feet long, a pier or jetty on the westerly side of the mouth about 290 feet long, the construction of a wharf about 700 feet upstream from the shore end of the. breakwater (transferred to Treasury Department in 1936), the construction of a jetty on the RIVERS AND HARBORS-NEW ENGLAND DIVISION 35 east bank a short distance farther upstream, and securing a depth of 4 feet at mean low tide for an average width of 100 feet up to Kennebunkport, a distance of about 1 mile, by dredging and rock removal. The mean tidal range is 9 feet; the extreme 13.5 feet. Work appears to have been commenced by the State of Massachusetts in 1798, since which date a number of small ap- propriations have been made for maintenance and further im- provement. The cost for new work for the completed project was $83,584. The approved estimate of cost (1950) for maintenance is $2,000. Those portions of the existing project adopted since 1829 were authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 2, 1829 Aug. 14, 1876 Repair of pier on east side of channel entrance... - Deepening at Wading Place and Mitchells Point.--- Annual Report 1875, p. 115.

This is a small river running through Flat Pond to Perkins Cove, which is the harbor for Ogunquit, a village on the coast of Maine 30 miles southwest of Portland. (See U. S. Coast and Geodetic Survey Chart No. 1205.) Existing project. This provides for a channel 5 feet deep and 40 feet wide in the Josias River from that depth in Perkins Cove to and including an anchorage basin of the same depth and about 3.2 acres in area in Flat Pond. The project depths refer to mean low water. The mean range of tide is 8.7 feet and the spring range is 10 feet. The estimate of cost for new work, approved in 1951, is $36- 000, exclusive of $35,000 expended by local interests for work on the project. The latest (1950) approved estimate of cost for an- nual maintenance is $1,800. 'The existing project was authorized by the River and Harbor Act of March 2, 1945 (H. Doc. 227, 76th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Fully complied with. Since the preparation of the project document, the residents of Ogunquit have spent $35,000 toward the accomplishment of the project and the River and Harbor Act of March 2, 1945, states "except that the useful work done on the project by local interests shall be accepted toward the fulfillment of the requirements of local cooperation." Terminal facilities. There are no wharves on this waterway. However, the town has erected a wood bulkhead on the left bank of the river. This bulkhead serves as a landing for local fisher- men. This structure provides adequate landing facilities for the needs of the harbor. Operations and results during fiscal year. Work on improve- ment dredging suspended at beginning of fiscal year was resumed on January 8, 1951. Contractor's right to proceed was terminated on May 3, 1951, due to his inability to complete the work. During this period 6,033 cubic yards of clay, gravel, mud and sand were removed. Work was readvertised on April 5, 1951, and bids were opened on May 25, 1951. The only bid received was re- jected as being excessive. Due to desires of local interests that no work be done during summer season, the work will be readver- tised in the fall of 1951. The costs were $11,059.63, all for new work. The expenditures were $10,298.85. Condition at end of fiscal year. The existing project is about 65 percent complete. The dredging has been largely completed by local interests at a cost of $35,000. Dredging of approximately 10,000 cubic yards of mud, sand, gravel, and stone remains to be done. The controlling depths at mean low water in the ap- proach channel from Perkins Cove to the Flat Pond Anchorage basin are 2.3 feet (1950), and in the Flat Pond Anchorage basin 2.3 feet (1950) for an area approximately 350 feet long by 250 feet wide.

Of the 14 wharves in the main harbor, 4 are used for the receipt of coal, 1 for the receipt of lumber, 2 for the receipt of fish and lobsters, and 2 in connection with yacht clubs. Five of the wharves are inactive and in poor condition. Two of these latter wharves are owned by the city of Lynn. One of the wharves has railroad connections and three have mechanical handling facilities. There are three wharves in the Saugus River. One is used for the receipt of coal and oil for a large manufacturing plant, one for fish, and the other used intermittently for general cargoes. The facilities are considered adequate for the existing commerce. (For the latest full description of terminal facilities, see Port and Terminal Facilities at the Ports of Northern New England-1941.) Operations and results during fiscal year. A condition survey by hired labor was completed in July 1950 at a cost of $2,208.59. The expenditures were $2,208.59. Condition at end of fiscal year. The project of July 3, 1930, for the 22-foot channel was completed in 1935. No work has 42 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 been done on the existing 25-foot project. Western Channel was dredged to 12 feet by the Commonwealth of Massachusetts (1916). Controlling depth was approximately 20 feet in the center half of the 25-foot channel, and approximately 17 feet deep in the outside quarters (1950), and generally 20 feet deep in the turning basin (1950). The costs and expenditures under the previous project have been $857,544.20, of which $755,042.91 was for new work and $102,501.29 for maintenance. There have been no costs and expenditures under the existing project. Proposed operations. No work is scheduled for fiscal years 1952 and 1953.

MYSTIC RIVER, MASS. Location. The Mystic River rises in Mystic Lakes, Mass., flows in a southeasterly direction, and empties into Boston Har- bor near the Boston Naval Shipyard. It is 7 miles in length. (See U. S. Coast and Geodetic Survey Chart No. 248 and U. S. Geologi- cal Survey Chart, "Boston".) Previous projects. Original project for the lower Mystic was adopted by the River and Harbor Act of March 3, 1899, and cur- tailed by the River and Harbor Act of June 25, 1910. For further details see page 1743 of Annual Report for 1915, and page 59 of Annual Report for 1938. There has been no previous project for the upper Mystic. Existing project. This provides for a channel 35 feet deep, extending from the upper limit of the 35-foot channel of Boston Harbor at the Mystic River bridge to approximately 300 feet downstream of the Malden Bridge, having widths varying from about 940 feet at its lower end, to about 1,060 feet at a point about 1,200 feet below the Malden Bridge, thence decreasing to 150 feet at its upper limit; a channel 20 feet deep from the head of the existing 35-foot channel to a point 800 feet above the Malden Bridge, with widths decreasing from 150 feet at the lower end to 75 feet through the drawspan, thence increasing to approximately 340 feet to form a turning basin above the bridge; a channel 6 feet deep and 100 feet wide from the Boston & RIVERS AND HARBORS-NEW ENGLAND DIVISION 43 Maine Railroad (western division) bridge to about 2,500 feet above Wellington Bridge, about 1 mile, and thence 4 feet deep, gradually narrowing from 100 feet to 50 feet at the upper end for about 2 miles to the head of commercial navigation at Crad- dock Bridge in Medford. The project depths refer to mean low water. The mean range of tide is 9.6 feet. The extreme range is 13,7 feet. The estimate of cost for new work, approved in 1951, is $4,685,600, exclusive of amounts expended on previous projects. The latest (1950) approved estimate of cost for annual main- tenance is $14,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents July 13,1892 Improvement of the upper Mystic-_ -- Annual Report, 1891, p. 672.

Doc. 2108, 64th Cong., 2d sess. Local cooperation. None required. Terminal facilities. In the section of the river benefited by the 35-foot channel project there are on the south bank of the river four wharves aggregating over 4,000 feet of berthing space used for the receipt, storage, and shipment of coal, lumber, and gypsum. These wharves consist of substantial stone or wooden bulkheads filled solid, and in some cases fronted by pile plat- forms. There is also on the south bank a lumber terminal, the largest of its kind on the Atlantic coast. It is equipped with the most modern mechanical appliances, has railroad connection, and occupies 4,400 feet of water front. On the north bank of the river within the scope of this improvement there is a large wharf for receipt and shipment of oil on an extensive scale; immedi- ately adjacent to this wharf is an extensive terminal constructed in connection with an iron works; on the west bank of Island End River, which flows into Mystic River on the north about mid- way of the 35-foot channel, are situated two large terminal wharves, of 800 feet dockage, for receipt and shipment of coal, coke, tar, and oil. These wharves are connected with the 35-foot channel by a channel 30 feet deep at mean low water, dredged by private interests. None of the above wharves is publicly owned, and none is open to general public use. 'Beyond the scope of the authorized 35-foot channel improve- ment, and within the scope of the 20-foot channel and the im- provement of the upper Mystic, there are on the south bank in 44 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Charlestown and Somerville about 1,850 feet, and on the north bank in Medford about 1,235 feet of available dockage, of which 450 feet on the south bank and 435 feet on the north bank are customarily in use. A large automobile assembly plant is located on the south bank in Somerville. The existing wharves consist of stone and wooden bulkheads, solid filled. None is publicly owned, but two are open to the public on payment of wharfage charges. The capacities of the lower Mystic are being utilized to a gratifying extent. These facilities are considered adequate for existing commerce. (For further details see "The Port of Boston, Mass.-Port Series No. 3- Revised 1946.") Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project is about 18 percent complete. To complete the project there remains the dredging of the 35-foot channel, including the removal of ledge in the channel. The controlling depths at mean low water in Mystic River at the time the various sections were last surveyed were: approximately 20 to 30 feet in the 35-foot channel (1950) ; 20 feet in the 20-foot channel (1948) ; 3 feet in the 6-foot chan- nel; and 3 feet in the 4-foot channel but narrowed in width (1946). The total costs and expenditures under the existing project from regular funds have been $353,500.33, of which $293,341.72 was for new work and $60,158.61 for maintenance. 'The total costs and expenditures under Emergency Relief appropriation funds have been $476,783.40, all for new work. The total costs under all funds have been $830,283.73, of which $770,125.12 was for new work and $60,158.61 was for maintenance. The total expenditures under all funds have been $830,283.73. Proposed operations. An allotment of $75,000 during fiscal year 1952 will be expended for maintenance dredging, by con- tract, to restore 30-foot channel depths. The sum of $2,310,000 can be profitably expended during fiscal year 1953 for new work dredging and rock removal, by contract, as follows: Dredging to 35 feet of the 35-foot project from Boston Harbor to the Malden Bridge ................................... $1,606,600 Initiation of removal of ledge by continuing contract ........ 703,400 2,310,000 RIVERS AND HARBORS--NEW ENGLAND DIVISION 45 Cost and financial summary Total to Fiscal year ending June 30- June 30, 1951, including fiscal years 1947 1948 1949 1950 1951 prior to 1947 New work: Appropriated---------------- ---------------------------- 895,848.32 Cost_.. ------------- _ . --..----------- ------------------------------------------ 895,848. 32 Expenditures -..... -- ------- 895,848 32 Maintenance: Appropriated... $1,705. 88 $10,500. 00 -$755. 56 $664.32------- - - 70,440. 53 Cost----...- . -1,705. 88 9,744.44- ------- 664.32 70,440.53 Expenditures... 1,705. 88 9,744. 44 664. 32-------------- 70,440..53 Other new work data: Estimated additional amount needed to be appropriated for completion of existing project ............. $3,915,600 12. BOSTON HARBOR, MASS. Location. This harbor includes all the expanse of tidewater lying within a line from Point Allerton to Point Shirley and extending from that line westward to the mainland. This com- prises an area of about 47 square miles, exclusive of the islands. (See U. S. Coast and Geodetic Survey Charts Nos. 246 and 248.) Previous projects.

Local cooperation. The River and Harbor Act of March 2, 1945, provides that the dredging of the proposed channel exten- sion shall not be undertaken until the Secretary of War is afforded satisfactory assurance that the Commonwealth af Massachusetts will construct the pier and provide a depth of 40 feet at mean low water in the berths at the new pier which will be served by the proposed channel extension. The construction of the new pier was authorized by the Massachusetts Legislature and actual con- struction started in 1950 and it is expected it will be completed in the latter part of 1951. Fully complied with. Assurances ap- proved by Chief of Engineers February 16, 1950. Terminal facilities. There are 183 wharves and piers in the Harbor, not including the Mystic River, Weymouth Fore River, and Town River, which are reported elsewhere. In addition, there are 4 ferry slips and 2 car floats. Of the terminals, 28 are publicly-owned, 3 are open to public use, 77 have mechanical handling facilities, and 57 have railroad connections. The facili- ties are considered adequate for the present requirements of commerce. (For the latest full description of Terminal Facilities, see Port Series No. 3--the Port of Boston, Mass., revised 1946.) Operations and results during the fiscal year. Improvement dredging, by contract, of the extension of the 40-foot main chan- nel was commenced on March 20, 1951, and was in progress at the end of the fiscal year. During the period 271,517 cubic yards of mud and clay were removed at a cost of $225,222.06, all for new work. The expenditures were $78,347.27 for new work. 48 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Survey of isolated shoal areas in Boston Harbor proper, by hired labor, in progress at beginning of fiscal year was completed in August 1950, at a cost of $27.52 for maintenance. Removal of obstructions and shoals in Reserved Channel was commenced on November 24, 1950, and completed on December 30, 1950, at a cost of $4,173.59, for maintenance. Snagging operations, by hired labor, were carried on during fiscal year at a cost of $3,566.27 for maintenance.

There are nine wharves in Weymouth Fore River all grouped near the head of the Federal improve- ment. Construction consists mainly of pile and timber piers ex- tending from timber or concrete bulkheads. There are 6,092 feet of berthing space available. Six of the wharves have railroad connections and six have mechanical handling facilities. Three of the wharves are used in connection with a large shipyard, two with oil terminals, one with an electric generating plant, one with a large soap manufacturing plant, and two with yacht clubs. There are no publicly owned wharves. The facilities are consid- ered adequate for the present needs of commerce. (For further description of terminal facilities see Port Series No. 3, Port of Boston, revised- 1946.) Operationsand results during fiscal year. Maintenance dredg- ing, by contract, was commenced on June 25, 1951, and was in progress at the end of the fiscal year. During the period 3,388 cubic yards of mud, sand, and silt were removed at a cost of $8,397.44. The expenditures were $3,284.40. Condition at end of fiscal year. The existing project was about 44 percent completed, the remaining portion consisting of dredging the 27-foot channel through Nantasket Gut and Hing- ham Bay to deep water in Weymouth Fore River west of Sheep Island, authorized by the River and Harbor Act of October 17, 1940, and the extension of the 27-foot channel so as to include the present 27-foot State-improved channel through and above Weymouth Fore River Bridge, and to provide in this section a combined channel and maneuvering basin of the same depth, authorized by the River and Harbor Act of March 2, 1945. The controlling depths were 17.6 feet from Nantasket Gut through Hingham Bay to abreast Sheep Island (1939); 26.0 feet for project width of 300 feet from abreast Grape Island to Wey- mouth Fore River Bridge (1949); 21.5 feet in channel and maneuvering basin upstream of Fore River Bridge (1948). The costs under the existing project have been $448,442.05, of which $355,227.34 was for new work and $93,214.71 was for mainte- nance. The expenditures have been $443,329.01. Proposed operations. The funds unexpended at the end of the fiscal year, amounting to $46,854.72, plus accounts receivable of $240.00, minus accounts payable of $5,353.04, leaving a balance of $41,741.68, will be applied toward completion of maintenance dredging in restoring project dimensions, by contract. 52 REPORT OF CHIEF OF ENGINEERS, U.

The River and Harbor Act of June 20, 1938, provided for an anchorage basin 18 feet deep at mean low water, 850 feet wide, and 2,125 feet in average length on the southeast side of the project channel near Long Beach, provided local interests furnish, free of cost to the United States, spoil- disposal areas for initial work and for subsequent maintenance as may be required, and contribute one-third the initial cost of the improvement. These conditions have not yet been complied with. Terminal facilities. There are three wharves and five boat- yards. Two of the wharves are publicly owned, one by the town of Plymouth and one by the Commonwealth of Massachusetts. These wharves are open to the public free of charge. The third wharf is used in connection with a yacht club. The wharves are of pile: and timber construction with timber docks. None of the wharves have railroad connections. Of the boatyards, two are used for the construction of new boats and the repair of old boats, and three are used for the servicing and storage of boats. The facilities are considered adequate for the present require- ments of commerce. Operations and results during fiscal year. A condition survey, by hired labor, was completed in August 1950, at a cost of $2,500.00. The expenditures were $2,500.00. Condition at end of fiscal year. The existing project was about 34 percent completed. No work has been done on the 18-foot anchorage basin authorized by the River and Harbor Act of June 20, 1938. Work of protecting by riprap the sections of Long Beach damaged by the storm of 1898 was completed in 1909. Eel River was restored to its former course in 1904. The dredg- ing of a channel 18 feet deep at mean low water was completed 54 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 in 1915. The 15-foot channel was completed in 1927. Controlling depths were 6 feet from the entrance in Cape Cod Bay to Beacon No. 4, thence 11 feet to the State Pier in the 18-foot channel (1950) ; 11 feet in the 15-foot channel (1950) ; 8 feet in the 15- foot turning basin at the town wharf (1950) ; and + 4 to 18 feet in the 18-foot anchorage (1950). The costs and expenditures under the existing project have been $324,722.30, of which $188,- 571.16 was for new work and $136,151.14 was for maintenance. In addition, $108,400 has been expended from contributed funds, of which $108,000 was for new work and $400 was for mainte- nance. Proposed operations. No work is scheduled in fiscal year 1952. 'The sum of $175,000 can be profitably expended during the fiscal year 1953 to do partial maintenance dredging, by contract, to a depth of 15 feet to allow commercial shipping access to the waterway with minimum delay in waiting for tides.

CAPE COD CANAL, MASS. Location.' This waterway is a sea-level canal, extending from the head of Buzzards Bay, Mass., to a point on Cape Cod Bay about 15 miles southeast of Plymouth Harbor, Mass. In general direction the canal trends from Buzzards Bay easterly to Cape Cod Bay. (See U. S. Coast and Geodetic Survey Charts Nos. 251 and 1208.) Existing project. This provides for the purchase of the Cape Cod Canal, including a 600-foot jetty and a 3,000-foot break- water at the east end of the Canal at a cost to the United States of $11,500,000; for an open canal 32 feet deep at mean low water, with widths of 540 feet in the land cut, 500 feet in a straight channel in Buzzards Bay to Wings Neck, and 700 feet beyond Wings Neck; mooring basins consisting of a basin on the south side of Hog Island channel 4,000 feet long, with widths varying from 0 to 400 feet, 32 feet deep at mean low water, and a basin at Sandwich 3,260 feet long, with widths varying from 0 to 385 RIVERS AND HARBORS-NEW ENGLAND DIVISION 55 feet, and 25 feet deep at mean low water; the construction of two fixed highway bridges having a horizontal clearance of 500 feet, and a vertical clearance of 135 feet at mean high water; the construction of a vertical lift railroad bridge with a 500-foot span and 135-foot clearance above mean high water when the span is raised; an improved lighting system; other accessory and minor features which may be deemed necessary and to be in accordance with plans approved by the Chief of Engineers, which include a dike extending southwesterly 10,700 feet from Stony Point, a dike between Hog and Mashnee Islands, a dike between Hog Island and Rocky Point, a small East Boat Basin, 13 feet deep at mean low water on the south bank of the canal, and a small, West Boat Basin 18 feet deep at mean low water on the north bank of the canal; a harbor of refuge for small vessels by dredging a channel 150 feet wide and 15 feet deep at mean low water into Onset Bay and to the town wharf in the village of Onset; for enlargement of the 15-foot turning basin at the town wharf and for an anchorage basin of about 16 acres, having a depth of 8 feet below mean low.water, located contig- uous to the, proposed 15-foot channel and turning basin. The land cut is 7.7 miles long, and with approach channels, the total length of the canal is 171/2 miles. The mean range of tide in Cape Cod Bay is 9.4 feet and in Buzzards Bay 4 feet. The mean range of spring tides is about 13 feet in Cape Cod Bay, and 6.5 feet in Buzzards Bay. The estimate of cost for new work, approved in 1951, is $31,- 544,000, including $11,500,000, purchase price of the canal and properties which were taken over by the United States on March 31, 1928. The latest approved (1950) estimate for annual cost of maintenance is $600,000 including $270,000 for operation and care.

The River and Harbor Act of March 2, 1945, provides that local interests contribute one-half of the first cost, but not to exceed $48,000, for the channel and turning basin in Onset Bay and hold and save the United States free from all claims for damages attributable to the work. It is expected that these requirements will be met. Terminal facilities. There are four terminals on the canal. Three are privately owned, one being used for the receipt and freezing of fish and two for the receipt and storage of oil. The fourth terminal is the State pier, owned by the Commonwealth of Massachusetts, and located on the north bank of the canal at. Bourne Neck. The terminals are considered adequate for the pur- poses for which they are used. Operations and results during the fiscal year. Maintenance: Dredging by U. S. hopper dredge in progress at beginning of the fiscal year was completed oi August 30, 1950. During the fiscal year 272,746 cubic yards, bin measurement, of mud, sand, and silt were removed at a cost of $96,582.70 Cleaning and painting of Buzzards Bay railroad bridge was commenced on October 16, 1950, and was in progress at the end of the fiscal year. 'The costs during the fiscal year were $16,- 020.14. Costs in connection with real estate activities amounted to $998.17 during the fiscal year. Channel work consisting of maintenance surveys of dikes and condition surveys of the chan- nel, mooring basins, and miscellaneous areas was carried on by hired labor during the fiscal year at a cost of $24,809.37. Maintenance of bridges, lights, power and signal systems, dol- phins, service roads, dikes, and drilling and blasting boulders was performed by hired labor at a cost of $73,428.03.

The costs during the fiscal year for operating and care were $253,938.33. The total costs during the fiscal year were $465,776.74 for maintenance, including $253,938.33 for operation and care. The total expenditures were $462,949.78. Condition at end of fiscal year. The existing project is sub- stantially complete except for dredging the 15-foot channel from deep water in the vicinity of Wickets Island to the town wharf at Onset and enlargement of the 15-foot turning basin at the town wharf, and an 8-foot anchorage basin contiguous thereto, authorized by the River and Harbor Act of March 2, 1945. The canal is crossed by two high-level highway bridges and a vertical lift railroad bridge. The canal in the land cut from the easterly entrance to station 430 has a least bottom width of 480 feet, ex- cept opposite the State Pier where the width is 450 feet. From station 430 to Wings Neck (Hog Island Channel) the width is 500 feet and beyond Wings Neck (Cleveland Ledge Channel) 700 feet. On June 30, 1951, the controlling depths at mean low water for this project were: Canal in land cut, 30 feet (1951) ; mooring basin, northside, easterly end, 19.3 feet (1951); Hog RIVERS AND HARBORS-NEW ENGLAND DIVISION 57 Island Channel, 30.6 feet, (1951); Cleveland Ledge Channel 29 feet (1951) ; mooring basin, south side, westerly end, depths varying from 21.3 to 32 feet (1951) ; the controlling depth in the Onset Channel was 16.5 feet (1943).

POLLOCK RIP SHOALS, NANTUCKET SOUND, MASS. Location. Pollock Rip Channel is the northerly passage through the shoals off the eastern entrance to Nantucket Sound connecting the deep water of the sound with that of the ocean. It is about 33 miles east from the harbor of Vineyard Haven, on the island of Marthas Vineyard, Mass., and 60 miles south from Provincetown Harbor at the northern extremity of Cape Cod. (See U. S. Coast and Geodetic Survey Chart No. 250.) Existing project. This provides for dredging through the shoals at the eastern entrance to Nantucket Sound with a Govern- ment dredge, which is to assist the natural agencies in obtaining such depth and width as may be found practicable, but not ex- ceeding a depth of 30 feet at mean low water and a width of 1 mile. The mean tidal ranges are about 3.7 feet at Monomoy Point, the nearest land, and 6.7 feet at Chatham Light, about 9 miles to the north of this point. The ranges of spring tides at these two points are 4.4 and 7.9 feet. The ranges are largely affected by direction and force of storms. The original expendi- RIVERS AND HARBORS-NEW ENGLAND DIVISION 59 ture authorized for experimental work was $250,000, and later the operation of a dredge was authorized at an estimated annual cost of $200,000. The cost of the completed project was $1,083,504.41 for new work. The latest approved (1950) estimate for annual cost of maintenance is $60,000.

A cut 2,000 feet wide has been dredged through Bearse and Pollock Rip Shoals. The controlling depth at mean low water was 30 feet for a width of about 1,750 feet, and about 12 feet along the north edge of the 2,000-foot channel (July 1946). The channel depths are adequate for existing commerce. The costs and expenditures under the existing project have been $1,083,504.41 for new work, and $732,405.15 for maintenance, a total of $1,815,909.56. Proposed operations. No work is scheduled for the fiscal year 1952. The sum of $75,000 can be profitably expended during fiscal year 1953 for maintenance operations with a United States hopper dredge, and for necessary surveys.

Cross Rip Shoals are a little southerly and easterly of the geo- graphical center of the sound. They are about 17 miles east from Vineyard Haven on the island of Marthas Vineyard and about 15 miles northwest from Nantucket Harbor. (See U. S. Coast and Geodetic Survey Chart No. 1209) Existing project. This provides for a channel 4,000 feet wide and 30 feet deep at mean low water between Half Moon Shoal and Cross Rip Shoal, about 1.7 miles. The mean tidal range is about 2 feet and the maximum range, due to the combined effect of wind and other causes, is 3 feet or more. The estimate of cost for new work, made in 1928, was $27,000. The latest (1950) approved estimate for annual cost of main- tenance is $8,000. The existing project was authorized by the River and Harbor Act of July 3, 1930 (H. Doc. 182, 70th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. None required. Terminal facilities. None. Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project was com- pleted in 1931. In April 1941, the controlling depth was 29 feet at mean low water, except for minor shoals, with a minimum depth of 26 feet along the edge opposite Cross Rip Shoal; 30 feet except for minor shoals, opposite Half Moon Shoal; and 30 feet and over through the sailing course. The costs and expen- ditures under the existing project have been $24,200.13 for new work, and $41,354.56 for maintenance, a total of $65,554.69. Proposed operations. No work is scheduled for fiscal year 1952. The sum of $45,000 can, be profitably expended during fiscal year 1953 for maintenance operations with a United States hopper dredge, and for necessary surveys.

The River and Harbor Act approved March 2, 1945, authorized the channel, anchorage, and jetty subject to the conditions that local interests furnish free of cost to the United States easements required for the construction of the jetty and suitable spoil disposal areas for new work and subse- quent .maintenance when and as required, hold and save the United: States free from claims for damages resulting from the improvement and contribute one-half the estimated cost of im- provement, but not to exceed $62,500. It is expected that these requirements will be met. The Commoiwealth of Massachusetts and local interests have expended nearly $235,000 in extending the breakwater to shore and in dredging channels in the outer and inner harbors. Terminal facilities. There are two town wharves in the inner harbor. One has a bulkheaded frontage of about 800 feet. Other private landings are available. Facilities are adequate for existing commerce. Operations and results during the fiscal year. Repairs to breakwater were in progress at the beginning of the fiscal year, and were completed on September 1, 1950. During the period 2,124 tons of stone were placed, at a cost of $19,210.68, all for maintenance.* The expenditures were $27,876.64. Condition at end of fiscal year. The existing project is about 52 percent :completed. The breakwater was completed in 1882, and :the dredging behind the breakwater in 1906. To com- plete the project requires dredging of the 12-foot channels and inner harbor anchorage and construction of the jetty. The con- trolling depths at mean low water were about 7 feet in the en- trance channel (1950); 8 feet in inner channel (1941) ; 6 feet in 62 REPORT OF CHIEF OF ENGINEERS, U. S.

The River and Harbor Act of July 25, 1912, imposed the condition that local interests construct a new bridge at Coggeshall Street with a draw opening of at least 100 feet and build a substantial wharf upon the city property at Belleville, the name given to the northern part of the city. These conditions have not been met, and there is no present prospect of their being complied with. The condition imposed by the River and Harbor Act of August 26, 1937, was fully complied with. The Commonwealth of Massachusetts expended approximately $120,000 in dredging a channel 25 feet deep and 100 feet wide from Fish Island nearly to Coggeshall Street Bridge. Terminal facilities. There are 31 wharves in the harbor with a total berthing space of about 19,000 feet. Twenty-four of these wharves are active, seven are inactive and in poor condition. RIVERS AND HARBORS-NEW ENGLAND DIVISION S 65 Their construction consists mainly of open pile and timber piers extending from solid-filled stone or timber bulkheads. Seven are publicly owned, one by the United States Government at Fort Rodman, two by the Commonwealth of Massachusetts, three by the city of New Bedford, and one by the town of Fairhaven. Five of the wharves have railroad connections and seven have mechanical handling facilities. These facilities are considered adequate for the present needs of commerce. For a further descrip- tion of terminal facilities see Port and Terminal Facilities of Southern New England, 1941. :Operations and results during fiscal year. Maintenance dredg- ing, by U.

The mean tidal range is about 4.6 feet and the maximum range, due to the combined effect of wind and other causes is 8. feet or more. The cost of the completed project for new work was $2,322,- 233.67, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of main- tenance is $65,000. The existing project was authorized by the River and Harbor Act of August 26, 1937 (H. Doc.- 173, 75th Cong., 1st sess.). The latest published map is in the project document, Local cooperation. Fully complied with. In addition to ex- tensive dredging prior to 1900 in the channel from Fox Point to the head of navigation, the city of Providence has since spent about $216,000 in maintaining a 20-foot depth in this channel. Terminal facilities. There are 35 wharves (in use or usable condition), including 1 owned by the State and 5 by the city adja- cent to the harbor area, Providence River below Crawford Street, and Seekonk River below Red Bridge. The total available berth- ing space is 19,170 feet. The municipal wharf at Field Point and the State pier are open to general public use for commercial purposes. One wharf is open to the public upon agreement with the owner. Thirteen of the wharves have rail connections. 'The facilities are considered adequate for existing commerce. (For further details see Port and Terminal Facilities of Southern New England-1941.) Operations and results during fiscal year. Maintenance dredg- ing, by contract, of the 35-foot channel from Field Point to Sabin Point was commenced on May 29, 1951, and was in prog- ress at the end of the fiscal year. During the period, 35,857 cubic yards of mud, sand, and silt were removed at a cost of RIVERS AND HARBORS-NEW ENGLAND DIVISION 73 $49,097.21, all for maintenance. The expenditures were $25,- 811.81. Condition at end of fiscal year. The existing project was com- pleted in 1949. Under the existing project, a channel 600 feet wide from the deep water of Narragansett Bay to the turn below Field Point, thence to Fox Point, with a width ranging up to 1,700 feet, has been dredged to a general depth of 35 feet. The head of commercial navigation is at Crawford Street Bridge, about 0.8 mile above Fox Point. The controlling depths at mean low water were as follows: 33 feet in the channel from abreast North Point to Field Point (1942-48) ; thence generally 35 feet . to Fox Point (1949). The costs under the existing project have been $3,297,936.97, of which $2,322,233.67 was for new work and $975,703.30 was for maintenance. The expenditures have been $3,274,651.57, all funds.

The State of Rhode Island and the town of South Kingstown have expended about $290,000, exclusive of a Federal Public Works Administration grant of $77,000, in dredging an anchor- age basin and channels, extending the stone east jetty, construct- ing sheetpile bulkhead, constructing a pier on each side of the basin, and repairing the east jetty and bulkhead following the hurricane of 1938. Terminal facilities. There are no terminal facilities on the Harbor of Refuge. Inside the entrance to the pond, the State of Rhode Island owns and operates two public piers, each with about 450 feet of berthing space, one on the east shore at Galilee and the other at Jerusalem, on the west shore. Fish are landed at both piers. The one at Galilee is the mainland terminus of the mail, passenger and freight boat service to Block Island. A number of small private piers, which are used by fishing and pleasure craft, are located on both sides of the basin. The United States Coast Guard has a boathouse and pier at Galilee. None of the piers has mechanical facilities for handling freight. At Wakefield, there is a boat yard amply equipped for servicing and storing small craft up to 5 feet in draft. The Point Judith Yacht Club has some pier facilities at this boat yard. There are no rail connections to any of the piers. Operations and results during fiscal year. Construction of sand arresting works in Point Judith Pond, in progress at the beginning of the fiscal year, was completed on November 4, 1950. During fiscal year, 4,347 short tons of stone were placed at a cost of $17,928.48, all for new work. Improvement dredging of 15-foot channel, 6-foot channel, and 10-foot anchorage, by contract, was commenced on July 20, 1950, and completed on November 8, 1950. During the period 193,689 cubic yards of sand and gravel, and an abandoned cable which was obstructing channel, were removed at a cost of $92,844.51, all for new work. Repairs to riprap breakwaters, by contract, were commenced on July 20, 1950, and completed on November 24, 1950. During period, 19,098 tons of stone were placed at a cost of $135,223.24, all for maintenance. The total costs were $228,409.23, of which $93,185.99 was for new work, and $135,223.24 for maintenance. The expenditures were $230,002.51, of which $94,791.80 was for new work, and $135,210.71 for maintenance. In addition, $17,587 was expended from contributed funds. Condition at end of fiscal year. The existing project was com- pleted in 1950. The breakwaters were completed in 1914 and dredging of shoals in the protected area was done in 1921. The controlling depths were as follows: West entrance about 19 feet (1939); east entrance about 22 feet (1939) ; 15 feet in the 15- foot channel into Point Judith Pond extending along the west side of the pond to a point 100 feet north of the State Pier at Jerusalem (1950) ; 15 feet in the 15-foot channel extending 100 feet north of the State Pier at Galilee (1950) ; 10 feet in the 76 REPORT OF CHIEF OF ENGINEERS, U.

Recommended modifications of project. On June 24, 1926, the Chief of Engineers recommended that this project be modified by eliminating the dredging of the outer harbor west of the entrance channel (H. Doc. 467, 69th Cong., 1st sess.). Local cooperation. None required. Terminal facilities. The only wharf in the harbor is the steel sheet-pile bulkhead which comprises the southern and eastern limits of the basin. Total docking space amounts to 500 feet. No mechanical handling facilities are available. The wharf is owned by the Town and open to the public. It is considered inadequate for the present general needs of boating in the harbor. There is ample room for the expansion of terminal facilities. Operations and results during fiscal year. Maintenance work on repairs to breakwaters, by contract, in progress at the begin- ning of fiscal year, was completed on August 7, 1950. During the fiscal year 4,496 tons of stone were placed at a cost of $45,841.95. The expenditures were $99,597.31. Condition at end of fiscal year. The existing project was about 94 percent complete. The breakwater and harbor walls were com- pleted in 1916. The inner harbor and basin have been dredged to project dimensions, and a channel 60 to 130 feet wide and 15 feet deep has been dredged from deep water outside the harbor up to the town wharf. To complete the project requires the dredging to a depth of 15 feet of the outer protected area adjacent to the dredged channel. The controlling depths at mean low water 78 REPORT OF CHIEF OF ENGINEERS, U. S.

On June 24, 1926, the Chief of Engineers recommended curtailment of the existing project by omitting construction of the proposed north jetty (H. Doc. 467, 69th Cong., 1st sess.). Local cooperation. The River and Harbor Act approved March 2, 1945, authorized improvement of inner harbor subject to the condition that local interests contribute 50 percent of the esti- mated first cost, but not to exceed $8,000, furnish free of cost to the United States suitably bulkheaded areas for spoil disposal for the initial work and subsequent maintenance, when and as required, and hold and save the United States free from claims for damages resulting from the improvement. These conditions have not been met. The State of Rhode Island and the town of New Shoreham expended $124,975.90 in dredging and protecting the channel into Great Salt Pond. Terminal facilities. These consist of a wharf with about 600 feet of publicly available berthage and several privately owned and operated small wharves and piers. These facilities are con- sidered adequate for existing commerce. Operations and results during fiscal year. Preliminary work, by hired labor, in connection with maintenance dredging in en- trance channel was completed at a cost of $794.48. The expendi- tures were $794.48, all for maintenance. Condition at end of fiscal year. The existing project was about 33 percent completed. The channel, 300 feet wide and 18 feet deep, with a central depth of 25 feet over a width of 150 feet, has been dredged into the pond. The south jetty was completed to its present length of 1,691 feet in 1905. The controlling depths are 16 feet in the vicinity of the Outer End Light and +2.0 feet in the vicinity of the Coast Guard Station in the 25-foot entrance channel (1951); 11 to 25 feet in 75-foot width east of central 150-foot channel; 0 to 25 feet in 75-foot width west of central 150-foot channel; 10 feet in entrance channel to inner harbor; and 11 to 14 feet in basin except for minor edge shoals. 'The 80 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 soundings were taken in 1943 and 1944. The jetty is in fair con- dition. To complete the project would require the further widening and deepening of the channel, the construction of the north jetty, and dredging of the inner harbor channel and basin. The costs and expenditures have been $189,036.65 for new work and $88,- 290.98 for maintenance, a total of $277,327.63. Proposed operations.

The bay and river channels have been dredged to project dimensions; except that the channel in the bay has a general width of 100 feet, the channel in the river at Pawcatuck Rocks a width of 80 feet, and there is a slight de- ficiency in depth at the channel edge in the vicinity of Rhodes Folly Beacon, due to ledge rock or large boulders deeply em- bedded in the bottom. The most obstructive boulders in the vicinity of Watch Hill have been removed, the work being com- pleted in 1913. The extension to the anchorage has been con- structed. The controlling depths at mean low water were as fol- lows: 9 feet in mairitained channel from abreast Rhodes Folly Light through Little Narragansett Bay, and in the Pawcatuck River to abreast Graves Neck, thence 8 feet to a point abreast Union Street, Westerly, Rhode Island (1948) ; 10 feet in channel through Little Narragansett Bay to Watch Hill Cove Anchorage basin (1949) ; and 10 feet in major portion of Watch Hill Cove anchorage (1949). To complete the project requires widening of the channel to 200 feet to Avondale, the removal of rock at Pawcatuck Rocks and in the vicinity of Rhodes Folly Beach. The costs under .the existing project have been $181,777.34 for new work, and $205,- 846.41 for maintenance, a total of $387,623.75. In addition, $20,- 000 was contributed for new work by local interests. The expenditures have been $387,623.75.

Hartford, now the head of commercial navigation, is 52 statute miles, by channel, from the mouth. (See U. S. Coast and Geodetic Survey Charts Nos. 215, 254, 255, and 256.) Previous project. Adopted by the River and Harbor Acts of July 14, 1836, and July 11, 1870. For further details see page 1754, Annual Report for 1915, and page 120, Annual Report for 1938. Project for Eightmile River, Conn.-Elimination as separate project. This provides for a channel 8 feet deep and 75 feet wide from deep water in the Connecticut River to Hamburg and for a turning basin of the same depth, 150 feet wide approximately RIVERS AND HARBORS-NEW ENGLAND DIVISION 83 300 feet long at Hamburg. The project was adopted by the River and Harbor Act of "June 25, 1910. The costs and expenditures have been $9,000, all for new work. In accordance with the River and Harbor Act of May 17, 1950, the project for Connecticut River below Hartford was modified to include the project for Eightmile River, which was eliminated as a separate project. The aforementioned act also provided for an anchorage basin 6 feet deep and about 6.3 acres in area in the upper cove at Hamburg. Existing project. This provides for a channel 15 feet deep at mean low water, 300 feet wide from the mouth to the Lyme rail- road bridge, about 3.4 miles, and thence 150 feet wide to Hart- ford, a total distance of 52 miles, the channel to be obtained by dredging and the construction of dikes, training walls, revet- ments, and the accessory works; for two riprap jetties at the mouth of the river, the tops to be 5 feet above high water and 6 feet wide, the easterly one about 2,300 feet and the westerly about 2,750 feet in length; for a training dike about 3,700 feet long at Hartford, and for an anchorage 11 feet deep, about 12 acres, and one, 6 feet deep, about 17 acres, in North Cove, Old Saybrook, with an entrance channel 11 feet deep and 100 feet wide; for a channel 18 feet deep, 75 feet wide about 1.5 miles in length from the Connecticut River to Hamburg; a turning basin of the same depth 150 feet wide and 300 feet long at Hamburg; and an anchorage area at Hamburg 6 feet deep, about 6.5 acres in area. The mean tidal range is 3.5 feet at the mouth, and at summer stage is about 1 foot at Hartford. The maximum tidal range at the mouth due to wind or other causes, is 8 feet or more. At Hartford the usual rise due to spring freshets is between 16 and 24 feet above mean low water. The maximum recorded freshets at Hartford (March 1936) was 35.5 feet above mean low water. Below Middletown the height of the crest of the freshet decreases rapidly.

ARMY, 1951 'Local. cooperation. The River and Harbor Act of August 30, 1935, authorized the 15-foot channel up to Hartford and addi- tional dikes, training walls, and revetments, subject to provision that local interests shall furnish, free of cost to the United States, suitable areas for the disposal of dredged material during initial construction and for future maintenance as and when needed. Areas have been furnished where required and it is un- derstood that future requirements will be met. The River and Harbor Act approved March 2, 1945, authorized the channel and anchorages in North Cove subject to the provisions that local interests contribute in cash $67,500, but not to exceed 50 percent of the initial construction cost and give assurances satisfactory to the Secretary of War that they will provide a suitable public landing in the cove. The River and Harbor Act of May 17, 1950, authorized the channel, anchorage and turning basin in Eightmile River provided that local interests contribute in cash 50 percent of the initial cost of dredging, but not to exceed $18,000; con- struct public landing facilities of a design- satisfactory to the Chief of Engineers; provide suitable spoil-disposal areas, as and when required, for new work and subsequent maintenance; and hold and save the United States free from claims for damages resulting from the improvement. It is expected that, these condi- tions will be met. Terminal facilities. On both the Connecticut and Eightmile Rivers there are two or three wharves at each of the river towns, one or more in each town being open to public use. At Hartford and at Middletown there is approximately one-half of wharf frontage along the west bank of the river. The facilities are con- sidered adequate for existing commerce. Operations and results during fiscal year. Preliminary work, by hired labor, in connection with maintenance dredging of various bars below Hartford was completed at a cost of $10,- 094.41. The expenditures were $9,843.50, all for maintenance. Condition at end of fiscal year. The existing project was about 71 percent complete. The 15-foot channel from the mouth to Hartford was completed in 1937. The Saybrook jetties and train- ing walls at Hartford, Clay Banks, and Sears Shoal were com- pleted in 1915. The stone dikes and timber spurs at Pistol Point, Glastonbury, Press Barn, Naubuc, Cys Hollow, and Clay Banks were completed in 1927 and those at Wethersfield in 1947. Timber pile dikes at Press Barn were completed in 1940 and at Glaston- bury Bend in 1943. The Clay Banks, Cys Hollow, Naubuc, Press Barn, Glastonbury (including two piers), and Gildersleeve Island and Reaches have been revetted. The jetties at Saybrook need re- pairs. The training walls, dikes, and revetments are generally in good condition. To complete the project requires the construction of additional permanent works, dredging the channel and anchor- age in North Cove, Old Saybrook, Connecticut, and the dredging of the .6-foot channel, turning basin, and anchorage in Eightmile River. The head of commercial navigation is at Hartford, 52 miles by channel from the mouth. A dam at Holyoke, Massachu- setts, 34 miles above Hartford, completely interrupts navigation.

The 35-foot main channel and the 22-foot channel and turning basin in Quinnipiac River were authorized subject to the conditions that local: interests furnish free of cost to the United States all lands, easements, and rights-of-way and suitable spoil disposal areas for the initial work and for subse- quent maintenance when and as required, and hold and save the United States free from damages resulting from the improve- ment. These requirements, as applied to the 35-foot channel, have been met, and assurances have been furnished that the require- ments for the 22-foot channel and turning basin in the Quinnipiac River will be met. These assurances were approved by the Chief of Engineers on June 2, 1947. Terminal facilities. The wharves and piers served by this im- provement are grouped near the head of the main harbor; on both sides of Mill River between Chapel Street and Grand Avenue; on both sides of Quinnipiac River throughout the greater part of its improved portion; at Oyster Point; and along the westerly side of West River. The total length of berthing space available at 50 wharves or piers is about 16,920 feet. One of the wharves is open to public use, 6 are open to public use upon agreement with the owners, and 9 have direct rail connections.

The latter act also authorized to be appropriated the additional sums of $6,000,000 for local protection works and $10,000,000 for reser- voirs. The act of October 26, 1942 (Public Law 759, 77th Cong., 2d sess.), further modified the plan by including the construction of Gully Brook conduit at Hartford, Conn. The Flood Control Act approved December 22, 1944, authorized the expenditure of $30,000,000 in addition to the previous author- ization for the comprehensive plan approved in 1938 and modified the plan by (1) directing specific consideration of an alternative plan of the Vermont State Water Conservation Board instead of the Williamsville Reservoir in the West River Basin, Vt., (2) di- recting consultation with the affected States during the course of investigations and transmission of the proposal and plans to each affected State for written views and recommendation for reser- voir projects heretofore authorized for construction at Cam- bridgeport, Ludlow, South Tunbridge and Gaysville and resubmission of the projects or modifications thereof to the Con- gress, and (3) rescinded the authorization for construction at the Sugar Hill site. The Flood Control Act of 1950 (Public, No. 576, 81st Cong., 2d sess.), modifies the project for flood control at Hartford, Conn., authorized by the Flood Control Act approved June 28, 1938, as amended, to include Folly Brook dike and conduit.

THOMASTON RESERVOIR, HOUSATONIC RIVER BASIN, CONN. Location. The site of the proposed Thomaston Reservoir is on the Naugatuck River about 30 miles above its junction with the Housatonic River and about 1 mile north of Thomaston, Conn. The reservoir will extend upstream approximately 6.4 miles. Existing project. This project provides for the construction of a rolled-fill earth and rock dam 1,800 feet long at the crest line, rising 136 feet above the stream bed and providing a storage capacity of 41,500 acre-feet. The spillway will consist of an open side channel constructed in rock on the right abutment and a low concrete weir with discharge capacity of 63,800 cubic feet per second. The outlet will consist of a 15-foot diameter tunnel 765 feet long. Control will be accomplished by gates mechanically operated through a shaft from a house above. The drainage area FLOOD CONTROL--NEW ENGLAND DIVISION 161 controlled is 97 square miles. The reservoir will be operated for the flood protection of Waterbury and the other communities downstream on the Naugatuck River. The estimated cost, revised in 1951, is $4,286,000 for construc- tion and $8,883,000 for lands and damages, including highway, railroad and utility relocations; a total of $13,169,000 for new work. The estimated cost for annual maintenance (operating and care) is $38,000. The existing project was authorized by the Flood Control Act approved December 22, 1944 (H.

This creek, also known as Hutchinson River, is a small tidal stream emptying into East Chester Bay, an indenta- tion in the north shore of Long Island Sound immediately north of Throgs Neck, 12 miles southwest of the Connecticut State line and 21 miles by water northeast of the Battery, New York City. (See U, S. Coast and Geodetic Survey Chart No. 223.) Previous projects. Adopted by the River and Harbor Acts of March 3, 1873, June 25, 1910, and July 3, 1930. For further de- tails see Annual Report for 1915, page 1761, Annual Report for 1929, page 167, Annual Report for 1938 page 163, and Annual Report for 1949, page 208. Existing project. 'This provides for a channel 10 feet deep at mean low wvater and generally 150 feet wide from Long Island Sound through East Chester Bay to a point 700 feet below the Boston Post Road Bridge, and thence 70 feet wide extending to a point where the creek divides into a Y, thence approximately 1,000 feet into the east branch of the Y and approximately 500 feet into the west branch of the Y; a passing basin south of the Boston Post Road Bridge; widening of the channel at the Boston Post Road Bridge; and for construction of a check dam at the head of navigation. Length of section included in project, 5 miles. Mean tidal range, 7.3 feet in the estuary; mean range of spring tides, 8.6 feet; irregular fluctuations due to wind and barometric pressure vary from 3.9 feet below mean low water up to 8.1 feet above mean high water. The estimate of cost for new work, made in 1951, is $664,000, exclusive of amounts expended on previous projects. The esti- mate of annual cost of maintenance, revised in 1950, is $29,800. The existing project was adopted by the River and Harbor Act of May 17, 1950 (H. Doc. 749, 80th Cong., 2d sess.). The latest published map is in the project document. Local cooperation. The River and Harbor Act of May 17, 1950, provides that local interests shall: (a) Furnish free of cost to the United States all lands, ease- ments, rights-of-way, and suitable areas for disposal of dredged RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 169 material during construction of the project and for subsequent maintenance, as and when required. (b) Hold and save the United States free from damages due to the construction works and subsequent maintenance. These conditions have not been fulfilled. Terminal facilities. There are 30 wharves with a total berth- age space of 9,528 feet available for use along the upper end of the waterway. Eight of the wharves are equipped with me- chanical handling devices. The existing terminal facilities are adequate to meet the present requirements of commerce. (For latest full description of terminal facilities, see Port and Terminal Facilities at the Port of New York, 1942, Corps of Engineers.) Operations and results during fiscal year. The cost of a survey to determine the condition of the channel was $1,661.73 for maintenance under the previous project. Condition at end of fiscal year. No work has been done under the existing project and there have been no costs or expenditures. When examined in April 1949 and June 1951, the controlling depth at mean low water was 7 feet for a width varying from 80 to 150 feet from East Chester Bay to 700 feet below the Boston Post Road Bridge, thence 8 feet for a width varying from 40 to 70 feet to 300 feet below the Fulton Avenue Bridge, thence 6 feet for a width varying from 40 to 70 feet to 300 feet above the Fulton Avenue Bridge, thence the depths decrease from 8 feet to 1-foot in the Y-shaped portion of the waterway. The minimum width through bridge draws is 59.6 feet. The head of navigation is about 1,550 feet above the Fulton Avenue Bridge. Proposed .operations. An allotment of $170,500 made during fiscal year 1952, will be applied to maintenance dredging by con- tract, (March to May 1952) to restore previous project depth of 8 feet in the channel at locations where critical shoaling has occurred. No work is scheduled for fiscal year 1953.

LAKE MONTAUK HARBOR, N. Y. Location. This harbor is located on the east end of Long Island, about 3 miles by land west of Montauk Point and 125 miles by water east of New York City. It is landlocked on the east, south and west sides and is connected on the north with Block Island Sound by an artificial inlet. (See U. S. Coast and Geodetic Survey Chart No. 1211.) Existing project. This provides for a channel 12 feet deep at mean low water and 150 feet wide extending from the 12-foot contour in Block Island Sound to the same depth in the existing yacht basin east of Star Island; for a boat basin 10 feet deep, 400 feet wide, and 900 feet long, located northwest of Star Island; and for the repair and extension shoreward of the east and west jetties. The length of section included in the project is 0.7 mile. Mean tidal range, 1.9 feet; mean range of spring tides, 2.2 feet; irregular fluctuations due to wind and barometric pressure vary from 2 feet below mean low water up to 7 feet above mean high water. The estimate of cost for new work, revised in 1951, is $395,000, exclusive of $82,737.73 from Navy Department funds. The esti- mate of annual cost of maintenance, made in 1950, is $7,500. The existing project was adopted by the River and Harbor Act of March 2, 1945 (H. Doc. 369, 76th Cong., 1st sess.). For latest published map see project document. Local cooperation. The River and Harbor Act of March 2, 1945, provides that local interests shall: 172 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 (a) Furnish, free of cost to the United States, spoil-disposal areas for initial work and for subsequent maintenance when and as required. (b) Hold and save the United States free from claims for dam- ages that may occur from the construction and maintenance of the improvements. (c) Convey to the United States, free of cost, all necessary rights-of-way and structures, including such absolute and inde- feasible easement in the body of water known as Lake Montauk Harbor and in the shores and bed therof as may be necessary to insure its permanent dedication to the use and purposes of a public navigable waterway. (d) Give assurances satisfactory to the Secretary of War that they will construct and maintain for free public use suitable road- ways to permit access to the boat basin and inner harbor. (e) Give assurances satisfactory to the Secretary of War that they will construct and maintain a suitable public landing open to all on equal and reasonable terms. And provided further that no work be done by the United States until the rights-of-way, structures, and easement specified in (c) above have been con- veyed to the United States; and title to rights-of-way required for roadways and landing facilities specified in (d) and (e) above, has been vested in the county of Suffolk or the town of East Hampton, in the State. of New York. Under date of December 8, 1942, the Chief of Engineers approved the instruments complying with condition (c) above, and partially complying with items (a) and (b). Work undertaken in Lake Montauk Harbor in 1942 was not then a part of an authorized river and harbor project but was performed for the Navy Department. The conditions of local co- operation required under the project were not considered wholly applicable. The supervisor, town of East Hampton, was notified of the conditions of local cooperation in letter dated January 24, 1946. Local interests have indicated that the remaining conditions will be met within the near future. Terminal facilities. Water terminals, seven in number, with a total available berthage of 1,390 feet are located on the east side of Star Island, the lake area south of the island, and at the inner end of entrance channel. None of the terminals has rail con- nections or is equipped with freight-handling devices. All the terminals are privately owned. Upon completion of a public landing to be constructed in accordance with the requirements of local cooperation, the terminals will be adequate for existing commerce. Operations and results during fiscal year. The cost and ex- penditures of a survey to determine the condition of the channel were $413.44 for maintenance. Condition at end of fiscal year. Work under the existing proj- ect was 31 percent completed. Dredging of the entrance channel and shoreward extension of the west jetty were performed from August 1942 to January 1943 at the request of the Navy Depart- ment with Navy funds.

EAST ROCKAWAY (DEBS) INLET, N. Y. Location. The inlet is situated on the south shore of Long Island between the main body of the island and the western end of Long Beach. It is 10 miles east of Rockaway Inlet and about 27 miles by water south and east from the Battery, New York City. (See U. S. Coast and Geodetic Survey Charts Nos. 579 and 1215.) Existing project. This provides for a channel 12 feet deep at mean low water and 250 feet wide from the 12-foot contour in the Atlantic Ocean to the 12-foot contour in Long Beach Chan- nel, a distance of about 0.6 mile, protected by jetties. Mean tidal range, 4.1 feet; mean range of spring tides, 4.9 feet; irregular fluctuations due to wind and barometric pressure vary from 4.1 feet below mean low water up to 5.2 feet above mean high water. The estimate of cost for new work made in 1951 is $1,227,000 (excluding $100,000, local contribution). The latest 1949 ap- proved estimate for annual cost of maintenance is $20,000. The existing project was adopted by the River and Harbor Act of July 3, 1930 (H. Doc. 19, 71st Cong., 1st sess.). The latest published map is in the project document. Local cooperation. The River and Harbor Act of July 3, 1930, provides that local interests shall contribute $100,000 to the cost of the work; give assurances satisfactory to the Secretary of War and the Chief of Engineers that they will provide and main- tain at their own expense interior channels suitable for naviga- tion, not less than 12 feet deep, from East Rockaway Inlet to the Hempstead-Oyster Bay line, a distance of about 15 miles, to Hewlett Harbor and to Freeport Harbor; furnish, without ex- pense to the United States, necessary land, easements, and rights- RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 177 of-way for construction and maintenance of the jetties, and agree to hold and save the United States free of claims for damages to public and private property resulting from the improvement. Assurances of compliance with the conditions of local coopera- tion precedent to construction of entrance channel and east jetty were approved by the Chief of Engineers and Secretary of War on July 14 and 15, 1932, respectively. Local contribution of $100,000 was deposited to the credit of the United States on August 23, 1932. Since the construction of the west jetty is not considered necessary at this time, easements, rights-of-way and release of claims for damages necessary for construction are not being secured. Terminal facilities. No terminals are within the area immedi- ately adjacent to the Federal improvement. The water front on the north side of Long Beach has been bulkheaded. There are five water terminals at Oceanside with an available wharfage of 2,000 feet. Three are oil terminals, of which one has a spur rail- road connection; the other two are unused at present. There are two terminals at Island Park having wharfage of 400 feet. There are public wharves at East Rockaway and Woodmere. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. The cost and ex- penditures of a survey to determine the condition of the channel were $454.22 for maintenance. Condition at end of fiscal year. Work under the existing proj- ect was commenced February 1933, and is about 85 percent com- plete. The east jetty, 4,250 feet long, was completed in July 1934. The project channel was completed in May 1935. When examined in September 1950 the controlling mean low water depth through the best available channel was 10.5 feet for a width of 250 feet. The east jetty was in good condition. The work remaining to be done under the existing project consists of building a west jetty, if necessary, to protect the channel.

The River and Harbor Act of March 2, 1945, provides that in lieu of conditions heretofore prescribed, local interests shall furnish free of cost to the United States, suitable areas for the disposal of dredged materials for new work and subsequent maintenance, when and as required, and shall hold and save the United States free from claims for damages resulting from the improvement. The city of New York was notified of the conditions of local cooperation in letter dated Jan- uary 25, 1946. In letter dated February 7, 1946, the mayor of the city of New York advised that disposal areas are available and that the necessary document "holding the United States free from claims for damages" would be executed. The River and Harbor Act of May 17, 1950, provides that local interests shall: (a) Furnish free of cost to the United States all lands, ease- ments, rights-of-way, and suitable areas for disposal of dredged material during construction of the project and for subsequent maintenance, as and when required. (b) Hold and save the United States free from damages due to .the construction works and subsequent maintenance. (c) Perform all necessary alterations to the existing terminals and bulkheads, and dredge adequate approaches thereto. These conditions have not been fulfilled. Terminal facilities. There are 60 terminals with a total berth- age of 21,372 feet located along the shores of Jamaica Bay, most of which are concentrated at 2 general localities; Mill Basin on the west shore, and from Seaside to and including Head of Bay on the south shore. Six of the terminals are available for public wharfage; none has direct rail connections. Nineteen yacht clubs and 18 boatyards, equipped with marine railways, are located within the bay. In addition, there are a number of small landings for pleasure craft. The existing facilities are considered adequate for existing commerce. (For latest full description of terminal facilities, see Port and Terminal Facilities of the Port of New York, 1942, Corps of Engineers.) Operations and results during fiscal year. The cost of a survey to determine :the condition of the channel was $430.09 for main- tenance. The total expenditure was $1,123.18. Condition at end of fiscal year. Work under the existing proj- ect was commenced August 1912 and is about 87 percent complete. 180 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The westerly interior channel from Barren Island to Fresh Creek Basin and the swinging basin at Mill Basin have been dredged to project dimensions. No new-work dredging of the entrance channel was done, since depths were greater than those required under the project. The east jetty, completed August 4, 1933, for a total length of about 8,400 feet, was in fair condition when examined in April 1949.

In the Upper Bay there are 45 piers with a total berthage of 70,723 feet and 11,171 feet of bulkheads and wharves available for dockage. In addition there are five car-float (rail- road) bridges and three ferry terminals. These terminals are located along the westerly shore of the bay, from St. George, Staten Island, to the Narrows and from Constable Hook, Bayonne, to Ellis Island. The terminals along the Brooklyn water front are reported under Bay Ridge and Red Hook Channels. The Lower Bay is largely undeveloped, the terminals being confined to Gravesend Bay. There are seven piers with a total berthage of 9,808 feet and one bulkhead providing dockage of 1,675 feet. Of the= terminals in the harbor, 27 are publicly owned, 4 are open to public use, 27 are equipped with mechanical-handling devices, and 24 have railroad connections. The facilities are considered adequate for present commerce. (For latest full description of terminal facilities see Port and Terminal Facilities at the Port of New York, 1942, Corps of Engineers.) Operations and results during fiscal year. The United States seagoing hopper dredge Essayons was employed intermittently from July 1, 1950 to June 5, 1951 in deepening Ambrose Channel to 45 feet and widening from 1,700 to 2,000 feet. During the fiscal year 943,400 cubic yards, place measurement, of material were removed at a cost of $470,594.59 for new work. The cost of condition surveys and surveys and engineering preliminary to dredging was $138.41 for new work and $5,902.69 for maintenance. The total cost of work was $476,635.69 - $470,733 for new work and $5,902.69 for maintenance. The total expenditure was $475,673.98. Condition at end of fiscal year. Work under the existing proj- ect was commenced in 1885 and is about 89 percent complete. Main Ship-Bayside-Gedney Channels were completed to a depth of 30 feet in February 1891. The deepening of Bayside-Gedney RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 183 Channel to 35 feet for a width of 800 feet was completed in June 1939. Ambrose Channel was completed to a depth of 40 feet for a width of 2,000 feet in April 1914. The center 800 feet was dredged to 45 feet in June 1944, and the westerly 600-foot strip in June 1947. One-half of the easterly 600-foot strip was dredged to 45 feet in March 1950, making the total width of the 45-foot channel 1,700 feet. Relocation of Anchorage Channel was completed to a depth of 40 feet in October 1932. The center 800 feet was dredged to 45 feet in June 1947 and the westerly 600-foot strip in April 1948. The channel between Staten Island and Hoffman and Swin- burne Islands was completed in December 1920 up to within 300 feet of the southerly limits of the project. The dredged chan- nel meets all the needs of navigation and no further work of improvement is contemplated for the present. The channel along the New Jersey pierhead line from Kill Van -Kull to Anchorage Channel was completed in March 1939. The Red Hook Flats anchorage was completed to 40 and 30 feet and the Liberty (Bedloe) Island anchorage was completed to 20 feet in October 1944.

Condition at end of fiscal year. Work under the existing proj- ect was commenced October 1903 and is about 68 percent com- plete. The easterly 500-foot width of channel from Anchorage Channel to East River was completed to a 40-foot depth in May 1935. The westerly 500-foot channel including the widening at the junction with the East River, was completed to a 35-foot depth for the northerly three-quarters of a mile of its length in December 1939, and for the southerly 2,000 feet in October 1944. The widen- ings at the junctions with Red Hook and Anchorage Channels were completed in December 1943. The work remaining to be done under the existing project consists of completing the deepen- ing to 35 feet of the westerly 500-foot channel.

(See U. S. Coast and Geodetic Survey Chart No. 274.) Previous projects. Adopted by the River and Harbor Act of June 23, 1874. For further details see Annual Report for 1915, page 1762, and Annual Report for 1938, page 210. Existing project. This provides for a continuous channel 15 feet deep at mean low water and 400 feet wide from East River to Hudson River, except in the vicinity of Washington Bridge, where the adopted width is 354 feet, and at the rock cut through Dyck- mans Meadow, where it is 350 feet and the depth is 18 feet. It also provides for straightening the channel at Johnson Iron Works by making a cut 15 feet deep and 400 feet wide. The length of channel included in the project is about 8 miles. The main tidal range varies, according to locality, from 4.9 feet at Willis Avenue Bridge to 3.8 feet at Spuyten Duyvil Bridge; range of spring tides, 5.9 and 4.5 feet, respectively. Irregular fluctuations due to wind and barometric pressure vary from 3.8 feet below mean low water up to 417 feet above mean high water at Willis Avenue Bridge and from 3.7 feet below mean low water up to 4 feet above mean high water at Spuyten Duyvil Bridge. The cost for new work, for the completed project, was $3,595,- 119, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $25,000.

About 5 miles of the water front are occupied by six piers with a total berthage of 2,692 feet and 23,699 feet of bulkheads and wharves available for dockage. Twenty-six of the terminals are owned by the city of New York. One of the latter is used as a barge canal terminal. Of the termi- nals owned by the city, six are open to the public on equal terms. Forty-three of the terminals are equipped with mechanical-han- RIVERS AND HARBORS--NEW YORK, N. Y., DISTRICT 197 dling devices and 12 have railroad connections. In addition, there are four railroad float bridges. The terminal facilities are consid- ered adequate for present needs. (For latest field description of terminal facilities, see Port and Terminal Facilities at the Port of New York, 1942, Corps of Engineers.) Operations and results during fiscal year. The cost of a survey to determine the condition of the channel was $987.02 for main- tenance. The total expenditure was $179.98. Condition at end of fiscal year. Work under the existing proj- ect was commenced January 1888 and was substantially completed May 1938. Remaining widening to be done in the section above High Bridge is prohibited by the proximity of bulkheads to the channel line. The present width is considered adequate for navi- gation. No further improvement is contemplated under the proj- ect. A channel 15 feet deep at mean low water and 400 feet wide has been excavated from East River to High Bridge, thence 15 feet deep and 350 to 400 feet wide to the Hudson River. The rock cut through Dyckmans Meadow was completed to 18-foot depth and 350-foot width in 1896. The straightening of the channel at Johnson Iron Works was completed to 15-foot depth and 400-foot width in 1938. The controlling depth from East River to Hudson River, as shown by examination made in December 1949-June 1951 was 15 feet at mean low water through a navigable channel varying from 50 to 400 feet in width, except for a shoal in the vicinity of Little Hell Gate having a minimum depth of 14 feet and scattered shoals between Sherman Creek and Broadway Bridge having a minimum depth of 11.5 feet. The total cost of the existing project to June 30, 1951 was, $3,866,311.53-$3,595,119.48 for new work and $271,192.05 for maintenance. The total expenditures were $3,865,504.49. Proposed operations.

Condition at end of fiscal year. Work under the existing proj- ect was commenced April 1873 and substantially completed No- vember 1938. Part of the diking originally proposed was not built because deemed of doubtful usefulness. Two parallel dikes of an aggregate length of about 5,000 feet, generally 350 feet apart, with a now obsolete spur from the old lighthouse south of the south dike, have been built across the bar at the mouth of the creek. A branch.dike about 1,000 feet long, extending northerly from the outer end of the north dike was also constructed. The project channel was completed in 1938. When examined in June 1948, the controlling depth at mean low water, from the Hudson River to the highway bridge, was 13 feet for a width varying from 50 to 100 feet, thence 10 feet for a width varying from 50 to 100 feet to the head of the project. The total cost and expenditures of the existing project to June 30, 1951 were $329,299.85-$123,108.63 for new work and $206,- 191.22 for maintenance. Proposedoperations. No work is scheduled for fiscal year 1952.

The original project for improvement by the United States was adopted by River and Harbor Act of June 30, 1834, and modified in 1852 and 1866. A second project was adopted by River and Harbor Act of July 13, 1892, and modified in 1899. For further details see page 1764, Annual Report for 1915, and page 226, Annual Report for 1938. RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 207 Existing project. This provides for a channel 27 feet deep at mean low water and 300 feet wide up: to Hudson; thence of same depth and 400 feet wide through rock cuts and 300 feet wide else- where, from Hudson to the site of the former Albany-Greenbush Bridge at Albany; thence 14 feet deep at lowest low water and generally 400 feet wide to the Federal lock at Troy; and thence of same depth and 200 feet wide to the southern limit of the State barge canal at Waterford; with widening at bends and in front of the cities of Troy and Albany to form harbors 12 feet deep at lowest low water; and removal of State dam at Troy and the con- struction of a lock and dam about 21/2 miles below Waterford. The channel is to be formed by dredgingand rock excavation, and to be maintained by dredging and by constructing new, and raising and repairing old, longitudinal dikes, built partly under previous projects and partly by the State of New York. The mean range of pool elevation above the Federal dam at Troy, in seasons of moderate rains is about 2.2 feet, as determined in 1934. The mean tidal range is about 4.7 feet at the Federal dam at Troy and about 4.6 feet at Albany, extreme range due to freshets is 33.4 and 25.7 feet, respectively. The normal pool level above the Federal dam from Troy to Waterford is 14.33 feet above mean sea level at Sandy Hook, N. J. In the tidal section of the river below the dam the assumed lowest low-water plane from Troy to Albany is 3 feet below mean sea level at Sandy Hook, N. J.

Final cost of $1,- 486.85 was reported during the fiscal year for maintenance of Cedar Hill Dike, section No. 3. United States derrick boat H. R. No. 1, with attendant plant, was employed in removing 4 shoals from the 14-foot channel at Albany from October 2 to November 24, 1950. During the fiscal year 9,758 cubic yards, scow measurement, of material were re- moved at a cost of $22,806.25 for maintenance. By use of Government plant and hired labor, snags and stumps, which formed a potential menace to navigation, and other ob- structions were removed from the shores and channel of the river during the fiscal year at a cost of $8,853.13 for main- tenance. The cost of engineering, surveys, and contingencies was $43,- 818.21 for maintenance. The lock and dam in the Hudson River at Troy, N. Y., was operated and maintained during the fiscal year. Operation of the lock for the 1950 navigation season was suspended December 11, 1950, and resumed April 2, 1951, for the 1951 season. Under contract for electrification of the lock machinery, work com- menced October 2, 1950, was in progress at the end of the fiscal year. The cost of work during the fiscal year was as follows: Operations, $48,371.69; ordinary maintenance and repairs, $26,- 519.31; improvements and betterments, $194,796.22; a total of $269,687.22. The total cost of the work was $346,651.66-$76,964.44 for maintenance and $269,687.22 for operation and care of the lock and dam at Troy, N. Y. The total expenditure was $310,816.23. Condition at end of fiscal year. Work under the existing proj- ect was commenced July 1910 and is about 96 percent complete. The construction of new lock and dam at 'Troy, removal of old dam at Troy, and construction of 15,545 linear feet of new dikes have been completed. In the reconstruction of old dikes, 39,672 linear feet have been raised to the adopted crest height. The channel from Albany to Waterford has been completed to a depth of 14 feet, with the exception of a small part of the widening to form a harbor at Troy, which work is not deemed necessary for the present. The work of deepening the channel south of Albany to 27 feet mean low water has been completed with the exception of about 1,500 linear feet at the northern end. The controlling mean low-water depth from New York City to Hudson, N. Y., is 27 feet for a width varying from 150 to 400 feet, thence 26 feet for a width varying from 150 to 450 feet to about 3,500 feet below the Dunn Memorial Bridge, thence 14 feet for a width varying from 150 to 300 feet to the Dunn Memorial Bridge. The controlling lowest low-water depth from Albany to the lock and dam at Troy is 14.0 feet for a width varying from 400 feet at Albany to 145 feet near the south entrance to the lock at Troy. At the lock entrance it is 14 feet deep for a width of 45 210 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 feet. The controlling pool-level depth above the lock at Troy to Waterford, the head of the improvement, is 14 feet for a width of about 200 feet.

This waterway consists of that portion of the New York State Barge Canal system extending from the Hudson River at Waterford to Oswego Harbor on Lake Ontario. (See U. S. Lake Survey Charts Nos. 182, 183, 184, and 185.) 212 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Existing project. This provides for the allotment of Federal funds to the State of New York for expenditure under suitable Federal control and supervision in the improvement of the canal connecting Lake Ontario with the Hudson River. The improve- ment provides for a depth of 13 feet below normal pool level through all locks between Waterford and Oswego, deepening be- tween locks to 14 feet below normal pool levels, widening at bends and elsewhere, and increasing the overhead clearance to 20 feet at maximum navigable stage at bridges and other overhead struc- tures. The widths of channel to be provided under the project are 104 feet in earth cuts, 120 feet in rock cuts, 200 feet in river sec- tions, with widening at bends and elsewhere as may be necessary. The length of the waterway included in this project is about 184 miles, of which 160 miles are in the Erie Canal from Water- ford to Three Rivers Point and 24 miles are in the Oswego Canal from Three Rivers Point to Oswego. The estimated cost for new work, made in 1951, is $31,536,000 of which not more than $27,000,000 shall be expended on deepen- ing between locks and raising of bridges and other overhead clearances as contained in River and Harbor Committee Doc. 20, 73d Cong., 2d sess.

The River and Harbor Act of March 2, 1945, authorized the deepening of the locks subject to the condi- tion that an agreement be entered into between the United States and the State of New York embodying certain limitations and provisions to safeguard the interests of general commerce and navigation, insure Federal control of the disposition of Federal funds, and provide for Federal supervision of the work per- formed. A supplemental agreement dated June 5, 1947, contain- ing all provisions necessary for efficient prosecution of the im- provement was entered into by the Chief of Engineers and the Department of Public Works, State of New York. The require- ments under the prior acts have been fully complied with. Terminal facilities. The State of New York has provided ter- minal and transfer facilities at all important points along the Erie and Oswego Canals, and at Buffalo, 'Troy, Albany, and New York Harbor. The freight-handling equipment, as well as the storage and dock facilities, is governed by the requirements of the par- ticular locality. The State-owned terminal at Oswego is equipped with a grain elevator of 1,000,000 bushels capacity. The Albany RIVERS AND HARBORS-NEW YORK, N. Y., DISTRICT 213 Port District Commission has erected a grain elevator of 13,500,- 000 bushels capacity at Albany. The Port of New York Authority grain terminal in New York Harbor on Gowanus Bay has a ca- pacity of approximately 1,800,000 bushels. Terminals at Buffalo, Rochester, Syracuse, Schenectady, Troy, Albany, and Oswego are provided with direct railroad connec- tions. All State-owed terminals are open to the public on equal terms. Lakeport terminals are extensive in character. The avail- able terminals appear ample to meet all requirements. Operations and results during fiscal year. The cost of engineer- ing studies and work preliminary to raising guard gates and lowering of sills at various locations between Waterford and Oswego, N. Y. was $558.29, for new work.

NARROWS OF LAKE CHAMPLAIN, N. Y. AND VT. Location. This waterway, 37 miles long, comprises the south- ern end of Lake Champlain and extends from Whitehall to Crown Point, N. Y. The portion included in the project extends from Whitehall, N. Y., at the southern extremity of the lake, northerly to Benson Landing, Vt., a distance of 13.5 miles. (See U. S. Lake Survey Chart No. 174.) Previous projects. Adopted by River and Harbor Acts of July 4, 1836, March 3, 1837, July 7, 1838, August 5, 1886, July 13, 1892, and March 3, 1899. For further details, see page 256, An- nual Report for 1932. Existing project. This provides for a channel extending from Whitehall, N. Y., at the head of Lake Champlain, to Benson Land- ing, to be 12 feet deep at low lake level and generally 200 feet wide, and the installation of fender booms at Putts Rock, Putts Leap, Narrows near Dresden, Pulpit Point, and Cedar Mountain. The reference plane of low lake level is 92.5 feet above mean sea level at Sandy Hook, N. J. The length of the section included in the project for improvement is about 13.5 miles. The usual an- nual variation of the lake level is 5.8 feet, and the extreme varia- tion varies from 0.6 foot below up to 8.8 feet above the low lake level. The estimate of cost for new work, revised in 1951, is $1,929,- 000 exclusive of amounts expended on previous projects. The 216 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 latest (1950) approved estimate for annual cost of maintenance is $9,000. The existing project was adopted by the River and Harbor Act of August 8, 1917 (H. Doc. 1387, 62d Cong., 3d sess.). The latest published map is in the project document. Terminal facilities. Terminal facilities are located in White- hall Harbor and consist of three timber wharves, aggregating 4,200 feet in length. The State of New York has constructed a barge canal terminal at Whitehall, just south of the terminus of the canal, which has been equipped with a 15-ton hand-operated derrick and a storehouse. The facilities are considered adequate for present commerce. Operations and results during fiscal year. Under a contract to restore project depth of 12 feet between Whitehall, N. Y., and the Elbow, work was commenced May 27, 1950, and was com- pleted July 13, 1950. During the fiscal year 21,926 cubic yards, place measurement, of material were removed at a cost of $41,- 703.14 for maintenance. Repairs to fender booms were made during the fiscal year by Government plant and hired labor, at a cost of $946.07 for main- tenance. 'The total cost of work was $42,649.21 for maintenance. The total expenditure was $91,055.20. Condition at end of fiscal year. Work under the existing proj- ect was commenced June 1919 and is about 47 percent complete. A channel 12 feet deep at low lake level and least width of 150 feet has been excavated throughout the length of the improve- ment, except at the Elbow, where the width is 110 feet. Fender booms have been placed at the Elbow (Putts Leap and Putts Rock) and opposite the Delaware & Hudson railroad trestle. No fender booms appear to be needed at the Narrows near Dresden, Pulpit Point, and Cedar Mountain. The controlling depths at low lake level, as disclosed by surveys made in July 1950, through the reach included in the project, were as follows: Locality Depth Width Feet Feet Whitehall to the Elbow.--- .. ..------ ------------------------------------ ..----.. 12 300 At the Elbow ------. .-- ...-- .......------------ 12 110 From the Elbow to Maple Bend--..----... ...----------------...----------------... 12 100-150 From Maple Bend to Red Rock Bay.. .......--------------------------------------- 12 150 From Red Rock Bay to Benson Landing...----.-------.----------------------- 12 100-150 The work remaining to be done to complete the project consists of widening the channel throughout its length to the project width of 200 feet. The total cost of the existing project to June 30, 1951, was $847,713.44-$566,811.14 for new work and $280,902.30 for main- tenance. The total expenditures were $847,117.37. Proposed operations. The balance unexpended at the end of the fiscal year amounting to $4,250 plus an allotment of $5,000 made during fiscal year 1952, a total of $9,250 will be applied as follows: RIVERS AND HARBORS-NEW YORK, N.

BURLINGTON HARBOR, VT. Location. This harbor, about 100 acres in extent, is located in a half-moon-shaped indentation in the eastern shore of Lake Champlain, about 40 statute miles south of the international boundary line, 70 statute miles north of the southern end or head of the lake, and 20 statute miles southeast of the harbor at Platts- burg, N. Y. (See U. S. Lake Survey Chart No. 172.) Existing project. This provides for a breakwater 6,000 feet long located about 1,000 feet from the shore and practically parallel with it, to be built of stone-filled timber cribs capped with large stone or concrete. The completed breakwater is to be in two sections, the northerly 500 feet being separated from the southerly 5,500 feet by a gap 200 feet wide for the purpose, of safety in entering the harbor during storms. The reference plane of low lake level is 92.5 feet above mean sea level at Sandy Hook, N. J. The level of the lake has varied from 0.6 foot below up to 8.8 feet above the low lake level. The usual annual variation is 5.8 feet. The cost for new work for the completed project was $706,414. The latest (1950) approved estimate for annual cost of mainte- nance is $8,000. The existing project was authorized by the following river and harbor acts: 218 REPORT OF CHIEF OF ENGINEERS, U. S.

Terminal facilities. The terminals consist of bulkhead shore front and open pile and solid filled piers having a total dockage of .6,520 feet. Of the terminals, five wharves, two piers, and one ferry slip are in use. Five of the terminals have railroad connec- tions. The facilities are considered adequate for present needs of commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project was prac- tically completed in 1890; part of the breakwater originally pro- posed was not built, the work completed being considered suf- ficient for the needs of navigation. The breakwater has been built in two sections, 364 and 3,793 feet in length, respectively, sep- arated by a gap of 200 feet. Sections of the stone and concrete superstructure of the breakwater have been displaced by wave action and the failure of the timbers in the tops of the wooden cribs. The controlling depth in August 1948 was about 10 feet at low lake level at the wharves, increasing considerably toward the breakwater. The distinction between new work and maintenance was not made in the early reports, hence it is impossible to separate the costs prior to July 1, 1886. The total cost and expenditures of the existing project to June 30, 1951, were $984,065.73; since June 30, 1886, the cost of main- tenance was $277,651.62, leaving $706,414.11 as the cost of new work, including maintenance prior to June 1, 1886. Proposed operations. No work is scheduled for the fiscal year 1952. The sum of $125,000 can be profitably expended during the fiscal year 1953 for repair of the breakwater.

Y., DISTRICT 219 24. PLATTSBURG HARBOR, N. Y. Location. This harbor embraces an area of about 25 acres along the westerly shore of Cumberland Bay, an arm of Lake Champlain. The harbor proper is that portion of the bay between the wharf front of the city of Plattsburg, N. Y., and the break- water constructed by the United States. (See U. S. Lake Survey Chart No. 172.) Existing project. This provides for a breakwater about 1,565 feet long, built of timber cribs filled with rubblestone and capped with large stone and extending from a point about 750 feet south of the outer face of South dock in a generally northeasterly direc- tion to a point about 1,400 feet from shore; for dredging to a depth of 9 feet at low lake level between the breakwater and the wharves, and for the revetment of the beach in front of the United States reservation. The reference plane of low lake level is 92.5 feet above mean sea level at Sandy Hook, N. J. The usual variation of the lake level is 5.8 feet, and the extreme variation varies from 0.6 foot below up to 8.8 feet above the low lake level. The cost of new work for the completed project, was $198,415. The latest (1950) approved estimate for annual cost of mainte- nance is $6,000.

The terminal facilities which serve the improvement consist of four timber wharves, aggregating 1,780 feet in length, 400 feet of which are open to the public; all are privately owned. The State of New York has constructed a barge canal terminal about 1 mile north of the breakwater. The existing facilities appear adequate for the existing commerce. Operations and results during fiscal year. Final cost of survey and engineering preliminary to contract dredging of the harbor was $299.40 for maintenance. Under a contract for maintenance dredging of the harbor be- tween the wharves and the breakwater, work was commenced July 17, 1950 and completed August 29, 1950. During the period 50,536.1 cubic yards, place measurement, were removed at a total cost of $60,770.92 for maintenance. The total cost of work was $61,070.32 for maintenance. The total expenditure was $61,947.69. Condition at end of fiscal year. The project has been com- pleted. The breakwater was completed in 1893, and the dredging 220 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 was completed in 1913. As now constructed, with its lake face protected by a rubble mound for practically its entire length, the breakwater is in a generally good condition except at the ends which are broken away. Maintenance will be necessary in the future. The controlling depth in August 1950 was 9 feet at low lake level. Revetment of the beach in front of the United States reservation has not been undertaken, as the material washed therefrom into the harbor can be more readily and economically removed by dredging. The distinction between new work and maintenance was not made in the early reports, hence it is impossible to separate the costs prior to July 1, 1910. The total costs and expenditures of the existing project to June 30, 1951 were $300,867.13; the cost of maintenance since June 30, 1910, amounts to $102,452.00, leaving $198,415.13 as the cost of new work and maintenance prior to July 1, 1910. Proposed operations. No work is scheduled for fiscal year 1952. The sum of $70,000 can be profitably expended during the fiscal year 1953 for repair of the breakwater by contract.

NEWARK BAY, HACKENSACK AND PASSAIC RIVERS, N. J. Location. Newark Bay is an estuary about 11/4 miles wide and 6 miles long, extending southerly from the confluence of the Hack- ensack and Passaic Rivers to New York and New Jersey Chan- nels. The Hackensack River rises near Haverstraw, Rockland County, N. Y., and flows into Newark Bay. It is about 45 miles long. The Passaic River rises in the highlands of northeastern New Jersey and flows into Newark Bay. It is about 80 miles long. (See U. S. Coast and Geodetic Survey Charts Nos. 287 and 369 and U. S. Geological Survey chart of New York City and vicinity.) Previous projects.

Fully complied with as required by the River and Harbor Act approved January 21, 1927, except that local interests are required to provide suitable spoil-disposal areas for maintenance dredging in the 30-foot channel in the Hacken- sack River above Central Railroad of New Jersey bridge; in the 10-foot channel in the Passaic River; and whenever required by the Secretary of War, for dredging in the 30-foot channel in Newark Bay and the Hackensack River below the Central Rail- road of New Jersey bridge, as required by the River and Harbor Act approved September 22, 1922. The River and Harbor Act of March 2, 1945, provides that local interests shall: (a) Agree to furnish free of cost to the United States, all lands, easements, rights-of-way and spoil disposal areas needed for new work and subsequent maintenance, when and as required; (b) Hold and save the United States free from claims for dam- ages resulting from the improvements; (c) Provide and maintain suitable berthing areas at Port Newark terminal. Assurances providing compliance with the local cooperation requirements under this act, were accepted by the Chief of Engi- neers on March 22, 1950. The sums of $265,000 and $31,000 were deposited to the credit of the United States by the Port of New York Authority on May 22, and December 29, 1950 to cover the cost of dredging the berthing areas at Port Newark Terminal, the work to be done by the United States in conjunction with the excavation of the project channel. It further provided, for the 10-foot channel in Passaic River from Montclair & Greenwood Lake Railroad bridge to the Eighth Street Bridge in Passaic, that when spoil-disposal areas are not available, or the placing of dredge spoil ashore is uneconomical as compared with other methods of disposal, local interests shall not be required to furnish disposal areas for maintenance dredging. Terminal facilities. There are 16 piers with a berthage of 8,525 feet, 55,300 feet of bulkheads available for dockage and a large shipyard along the waterways included in the project. RIVERS AND HARBORS--NEW YORK, N. Y., DISTRICT 223 Thirteen of the terminals are publicly owned, the largest of which, Port Newark, owned and operated by the New York Port Au- thority, provides about 11,000 feet of wharfage. Nine of the terminals are open for public use, 56 are equipped with mechani- cal handling devices and 66 have railroad connections. The facili- ties are considered adequate for existing commerce. (For latest full description of terminal facilities see Port and Terminal Fa- cilities at the Port of New York, 1942, Corps of Engineers.) Operations and results during fiscal year. Under a contract for new work dredging to a depth of 35 feet of the project chan- nel in Newark Bay including the northerly 1,900 feet of the main channel and the branch and inshore channels and for dredging berthing areas at Port Newark terminal, the latter being done for local interests, work was commenced June 14, 1950, and was completed March 27, 1951. During the fiscal year 1,647,553 cubic yards, place measurement, of material were removed from the project channel, and 347,857 cubic yards, place measurement, of material from the berthing areas. The cost of dredging, ex- clusive of $150,319.57 contributed funds for dredging berthing areas, was $707,077.78 for new work. Under a contract for new work dredging and rock removal to a depth of 37 feet in the inshore channel and for dredging and rock removal at adjacent berthing areas at Port Newark terminal, the latter being done for local interests, work was com- menced January 29, 1951, and was completed May 12, 1951. During the fiscal year 55,772 cubic yards, place measurement, of material were removed from the project channel, and 40,360 yards, place measurement of material from the berthing areas. The cost, exclusive of $97,115.83 contributed funds for dredging and rock removal of berthing areas, was $137,988.28 for new work. The United States lighter Babcock was engaged in removal of miscellaneous shoals from the inshore channel and adjacent berth- ing areas at Port Newark terminal, the latter being done for local interests, during the period February 20-21, 1951. The cost, ex- clusive of $663.22 contributed funds, was $1,156.02 for new work. Under a contract for new work dredging to a depth of 35 feet in Newark Bay, from 1,200 feet south of Central Railroad of New Jersey bridge to the entrance channel to Port Newark terminal, work was commenced on February 18, 1951, and was in progress at the end of the fiscal year.

The Winooski River rises in the northeastern part of Vermont and flows westerly about 90 miles into Lake Cham- plain, about 4 miles north of Burlington, Vt. It lies wholly within the State and has a drainage area of about 1,080 square miles. The Waterbury Reservoir with a drainage area of 109 square FLOOD CONTROL--NEW YORK, N. Y., DISTRICT 249 miles: is located on the Waterbury River, which enters the Winoo- ski River 42 miles above the mouth, about 2 miles below Water- bury, Vt. (See U. S. Geological survey map covering Camels Hump, Vt., quadrange.) Existing project. The existing dam is of rolled earth-fill type 1,800 feet long at its crest rising 155 feet above the stream bed, and providing a total storage capacity to 64,700 acre-feet, of which 27,900 acre-feet are reserved for flood-control. This project provides for modification of the Waterbury Dam so as to accom- modate safely the maximum probable flood. The work consists of increasing the height of the dam 3 feet to elevation 633 feet mean sea level, the installation of one extra 35-foot tainter gate, thus providing a total of three gates and reducing the length of fixed crest spillway by 38 feet, the installation of a gasoline-engine generator for the emergency operation of the gates in case of power failure, riprapping new embankment, restoring road sur- face and guard rails, extending the existing bridge over the new tainter gate section, and performing such incidental work as may be required. Construction of the Waterbury Reservoir was com- pleted in 1938 under authority granted by the Director, Emer- gency Conservation Work on June 2, 1933. The work was performed by the Civilian Conservation Corps under the super- vison of the Chief of Engineers, United States Army.

Adams, Mass., is situated on the Hoosic River about 6 miles below the source of the river. (See U. S. Geological Survey map covering Greylock, Mass.-Vt., quadrangle.) Existing project. This provides for channel improvements, for a distance of approximately 2.2 miles, with flood walls on both banks of the stream from high ground below Plunkett Dam to a 260 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 proposed weir above Commercial Street; a concrete paved chute or flume from this weir to a proposed stilling basin above the mouth of the Tophet Brook and below Hoosac Street; and an im- proved earth channel with flood walls, earth levees, a closure levee and structure and two check dams from the mouth of Tophet Brook to Lime Street; a concrete chute drop structure and stilling basin on Tophet Brook' from Hoosac Street to junction with Hoosic River. Other work appurtenant to the project involves alteration of existing raceways, bridge reconstruction, street and utility relocations, and channel improvement of tributary brooks. The estimated Federal cost for new work, revised in 1951, is $4,935,000, exclusive of land and other work to be provided by local interests at an estimated cost of $500,000. The existing project was authorized by the Flood Control Act approved August 18, 1941. (See H. Doc. 182, 76th Cong., 1st sess., which contains the latest published map.) Local cooperation. See pages 4-5 for requirements. In addition to the usual requirements for local cooperation as provided by law, local interests are required to give assurances satisfactory to the Secretary of the Army that they will insure against future encroachments upon the flood channels to be provided by the im- provements. General assurances of local cooperation in the entire project were executed by the Board of Selectmen, town of Adams, on November 22, 1949. The assurances were approved on January 31, 1950. In accordance with a law enacted by the Common- wealth of Massachusetts in 1950, the State Department of Public Works on November 21, 1950 furnished general assurances of local cooperation on the part of the State in the project, with the exception of operation and maintenance of the project in the town of Adams which remains a responsibility of the town under assurances previously furnished by the town of Adams. Lands, easements, and rights-of-way for initiation of work were acquired by local interests on March 29, 1950.

Existing project. This provides for a channel 28 feet deep and 300 feet wide from Allegheny Avenue, Philadelphia, to the Penn- sylvania Railroad bridge at Delair; thence 25 feet deep and 300 feet wide to the upper end of the municipal marine terminal at Trenton, including a turning basin 500 feet wide and 1,700 feet long at the terminal; widening the 25-foot channel at bends above Delair; and the maintenance of a channel 12 feet deep and 200 feet wide from the upper end of the 25-foot channel to the Penn- sylvania Railroad bridge at Trenton, dredged under a previous project. The project also provides for an auxiliary channel 20 feet deep and 200 feet wide east of Burlington Island extending east- erly from the main channel to the upper end of the United States Pipe & Foundry Co.'s property at East Burlington, with a turn- ing basin 450 feet wide at the upper end, an anchorage 22 feet deep, 100 feet wide, and 400 feet long along its west or landward side and 800 feet long along the west side of the ship channel, opposite the mouth of Biles Creek, Pa., and for the initial exca- vation only, of a cross channel 8 feet deep and 200 feet wide through the artificial island opposite Delanco, N. J. The total length of the section included in the project is about 301/2 miles, excluding the auxiliary channel east of Burlington Island which is 1.4 miles long, and the cross channel opposite Delanco. The lower end is about 55 miles above the mouth of the river at Liston Point and about 105 miles above the harbor of refuge at the mouth of Delaware Bay. All depths refer to the plane of mean low water. The mean tidal range at Trenton is 6.7 feet, an increase of 1.3 foot since the completion of the 25-foot channel. Freshets, which occur usually during February and March, at- tain a height of 9 to 20 feet above mean low water in the vicinity of Trenton. Navigation is occasionally suspended during a portion of the winter months on account of ice. The estimate of cost for new work, revised in 1951, is $5,243,- 000, exclusive of amounts expended on previous projects and $15,- 000 contributed funds. The latest (1950) approved estimate for annual cost of maintenance is $232,000.

DELAWARE RIVER AT CAMDEN, N. J. Location. Camden, N. J., is located on the east bank of the Delaware River, directly opposite the city of Philadelphia, Pa. It is about 51 miles above the mouth of the river and about 101 miles above the harbor of refuge at the mouth of Delaware Bay. (See U. S. Coast and Geodetic Survey-Charts Nos. 295 and 280.) Previous projects. Adopted by River and Harbor Act of June 25, 1910. No work was done on this project. For further details, see page 321, Annual Report for 1932. Existing project. This provides for dredging in front of Cam- den to a depth of 18 feet from that depth north of Cooper Point to Berkley Street and 30 feet from the latter point to Newton Creek, with the depth increased to 37 feet in front of the Camden marine terminals, these depths extending from the ship channel in Dela- ware River to a line parallel with and 50 feet distant from the established pierhead line, and the 37-foot depth in front of the Camden marine terminals extending about 2,900 feet along the RIVERS AND HARBORS-PHILADELPHIA, PA., DISTRICT 277 inshore side and about 5,100 feet along the ship channel. All depths refer to the plane of mean low water. The distance from Cooper Point to Berkley Street is about 1.5 miles, and from Berkley Street to Newton Creek is about 2.5 miles. The lower end of the project is about 49 miles above the mouth of the river at Liston Point and about 99 miles above the harbor of refuge at the mouth of Delaware Bay. The mean tidal range is 6.0 feet and the extreme tidal range under the influence of prolonged heavy winds is about 14 feet. The estimate of cost for new work, revised in 1951, is $1,086,- 000, exclusive of $15,000 contributed funds. The latest (1950) estimate for annual cost of maintenance is $60,000.

INLAND WATERWAY FROM DELAWARE RIVER TO CHESAPEAKE BAY, DEL., AND MD. Location. This waterway begins at Reedy Point on Delaware River, about 41 miles below Philadelphia, Pa., and passes through the sea level Chesapeake & Delaware Canal, a distance of 14 miles, to Back Creek, at Chesapeake City, Md. It then passes for 5 miles down Back Creek, thence 9 miles down Elk River to Chesapeake Bay and thence 18 miles down Chesapeake Bay to a point near Pooles Island. A branch channel connects Delaware River at Delaware City, Del., with the main channel at a point about 11/2 miles west of Reedy Point. (See U. S. Coast and Geodetic Survey Charts Nos. 294, 1226, 570, and 572.) Previous projects. The River and Harbor Act of August 8, 1917, made appropriation for preliminary studies with a view to taking over the Chesapeake & Delaware Canal. The River and Harbor Act of March 2, 1919, provided for the purchase of the Chesapeake & Delaware Canal. The River and Harbor Acts of January 21, 1927, and July 3, 1930, provided for dredging in Back Creek, Md., and the construction of bridges and roadways. For further details see Annual Report for 1934, page 242, and Annual Report for 1938, page 312. Existing project. This provides for a sea-level channel to ac- commodate vessels drawing 25 feet and having a depth of 27 feet and a width of 250 feet from Delaware River to Elk River and thence 400 feet wide down Elk River and Chesapeake Bay to deep water at or near Pooles Island; alteration of existing bridges over the canal; extension of the entrance jetties at Reedy Point; the enlargement of the anchorage and mooring basin in Back Creek to afford an area about 400 feet wide, 1,000 feet long, and 12 feet deep, including provision of sluice gates at the fixed highway bridge; dredging the Delaware City Branch Channel to a depth of 8 feet and a width of 50 feet; deepening the existing basin to the same depth; revetment of both banks east of Fifth Street Bridge; and construction of bulkheads. 286 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The project also provides for the construction of a four-lane high-level fixed highway bridge across the canal at or near St. Georges, Del., of such type, design, and clearance for navigation as are approved by the Chief of Engineers. The total length of the section included in the project, excluding the Delaware City Branch Channel, which is about 2 miles long, is about 46 miles. All depths refer to the plane of mean low water in Delaware River. The mean tidal range at the Delaware River entrance is 5.4 feet and in Elk River at the mouth of Back Creek, 2.2 feet. The extreme tidal range is from 6.3 feet above mean high water to 3.0 feet below mean low water. The estimate of cost for new work, revised in 1951, is $14,666,- 000. The latest (1949) approved estimate of cost for annual main- tenance is $825,000, including $225,000 for operation and care of the waterway. The existing project was adopted by the River and Harbor Act of August 30, 1935 (H. Doc. 201, 72d Cong., 1st sess., and Rivers and Harbors Committee Docs. 18 and 24, 73d Cong., 2d sess.). The act approved August 7, 1939 (Public Law 310, 76th Cong., 1st sess.), authorized the construction of a four-lane high-level fixed highway bridge at or near St. Georges, Del. The latest published map of the canal is found in Rivers and Harbors Committee Document No. 24, Seventy-third Congress, second session. Operation and care of the canal and appurtenant works were included in the project July 1, 1935, under the pro- visions of the Permanent Appropriations Repeal Act approved June 26, 1934. Local cooperation. Fully complied with. Terminal facilities. Ample mooring facilities at the eastern and western ends of the canal and bulkheads at Delaware City and St. Georges have been constructed by the United States. A harbor for small boats has been provided and a wharf has been constructed at Chesapeake City. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance, con- tract: Dredging Reedy Point Entrance was in progress from June 15 to 27, 1951.

ABSECON INLET, N. J. Location. This inlet is located on the coast of New Jersey about 65 miles north of Delaware breakwater, between Brigan- tine Beach on the north and Absecon Beach on the south. It forms the entrance to the harbor at Atlantic City, N. J. (See U. S. Coast and Geodetic Survey Charts Nos. 826 and 1217.) Previous project. Adopted by River and Harbor Act of July 25, 1912. The project was completed in 1916. For further details see Annual Report for 1936, page 319. Existing project. This provides for an inlet entrance channel 20 feet deep at mean low water and 400 feet wide, for an entrance channel 15 feet deep and 200 feet wide from the inlet channel into Clam Creek, and for a turning basin 15 feet deep within Clam Creek. The act authorizing the inlet entrance channel also provides that should the channel at any time have a deleterious effect on the Atlantic City Beach, work upon the improvement may cease, it being understood that the project is adopted on the basis that the interests of the beach in front of the city are superior to those of the inlet. The total length of the section in- cluded in the project is about 11/2 miles. The mean tidal range in the ocean is 4 feet and at the inlet gorge 3.6 feet. The extreme tidal range, due to ocean storms, is about 11 feet. The estimate of cost for new work, revised in 1951, is $249,000. The latest (1949) estimate for annual cost of maintenance is $200,000.

There are nine wharves served by this improvement; one is Government-owned, six are privately owned and open to general public use upon payment of moderate wharfage, and two are publicly owned. Three of the wharves have direct railroad connection. There is also a continuous line of piers or landing places for pleasure craft on both sides of the large basins which indent the south shore of the inner channel. There are three shipyards and three marine railways at this locality. The facilities are considered adequate for the existing commerce. Operations and results during fiscal year. Demobilization costs incurred by United States hopper dredge Lyman in con- nection with maintenance dredging completed near the end of the previous fiscal year were $3,776.09. Surveys and channel examinations were made at a cost of $2,920.66 for maintenance. The cost of all work was $6,696.75 for maintenance. The expenditures were $10,750.09. Condition at end of fiscal year. The project was about 92 percent complete. The inlet entrance channel was completed in 1938. The work remaining to be done is the dredging of an entrance channel from the inlet channel into Clam Creek and a turning basin in Clam Creek. The controlling depth at mean low water, in January 1951, in the channel through the outer bar was 13.5 feet. The costs and expenditures under the existing project were $208,647.66 for new work and $1,663,234.80 for maintenance, a total of $1,871,882.46. Proposed operations. It is proposed to apply the funds un- expended on June 30, 1951, amounting to $67,629.83 for main- tenance dredging in the inlet channel with a United States hopper dredge in August and September 1951. The additional sum of $200,000 can be profitably expended during the fiscal year 1953 for maintenance dredging in the inlet channel with a United States hopper dredge, as required.

It then passes through a series of bays, lagoons, and thoroughfares along the New Jersey coast to Cape May Harbor ; thence across Cape May County to Delaware Bay through a land cut by way of the New England Creek basin. (See U. S. Coast and Geodetic Survey Charts Nos. 234, 795, 825, 826, 827, 1216, 1217, 1218, and 1219.) Existing project. This provides for a channel 12 feet deep at mean low water and generally 100 feet wide, extending from the Atlantic Ocean at Manasquan Inlet, N. J., to Delaware Bay above Cape May, N. J., by the further improvement of Manasquan River and Inlet, N. J., and the present New Jersey Intracoastal Water- way, and by the construction of a canal of similar dimensions from Cape May Harbor to Delaware Bay via the New England Creek basin, with adequate jetties at the Delaware Bay entrance. The- total length of the project is about 117 miles. Normal tidal range in sections of the waterway remote from inlets is 0.5 foot. Near the inlets the mean tidal range generally is 3 feet; in the ocean, 4 feet; at the head of Cape May Harbor, 4.6 feet; and in Delaware Bay, near the entrance, 4.7 feet. The estimate of cost for new work, revised in 1951, is $6,054,- 000, exclusive of $1,824,940 Navy Department funds and $99,000 contributed by local interests. The latest (1950) approved esti- mate for annual cost of maintenance is $400,000. The existing project was adopted by the River and Harbor Act approved March 2, 1945 (H. Doc. 133, 76th Cong., 1st sess.). The latest published map is in the project document. The River and Harbor Act approved July 24, 1946 (Public 525, 79th Cong., 2d sess.), authorized the use, for a period not to exceed 5 years, of funds from appropriations heretofore or here- after made for maintenance and improvement of rivers and harbors, for the maintenance of the canal from Cape May Harbor to Delaware Bay constructed as an emergency wartime project with Navy Department funds, including the cost of maintaining the temporary railroad and seashore highway bridges over the canal. Local cooperation. The project is subject to the conditions that the State of New Jersey cede to the United States all right, title, and interest that it has acquired to lands, easements, rights- of-way, and structures other than bridges for the Manasquan- Bayhead Canal; that the State of New Jersey furnish, free of cost to the United States, all lands, easements, rights-of-way, and disposal areas required for construction of the Cape May Canal and for improvement of the proposed waterway and for 306 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 their subsequent maintenance; that local interests provide, main- tain, and operate suitable bridges over the waterway; that the State of New Jersey donate to the United States the navigation aids in use on the present New Jersey Intracoastal Waterway, and that the State of New Jersey hold and save the United States and its agents free from any claims for damages resulting from the work of improvement. The only measures taken by local inter- ests to comply with the specified requirements are that the State of New Jersey has contributed $99,000 toward the acquisition of land for the rights-of-way and disposal areas for the Cape May Canal, assumed the maintenance and operation of one temporary highway bridge constructed by the Federal Government across the canal, and taken the necessary legislative action to permit the Department of Conservation and Economic Development to meet the specified requirements. It is expected that the conditions of local cooperation imposed on the project will be fully met, during the fiscal year 1952. Terminal facilities. There are numerous piers, !.wharves, and docks at resorts located at or adjacent to the waterway, most of which are open to general public use, and fuel, water and other supplies are readily available. Public and privately owned boat basins are located in a number of streams entering the bays and thoroughfares through which the waterway passes. Boat repair and storage yards with marine railways for small craft are also scattered along the waterway. Transfer facilities, including facili- ties for icing, storing, and shipping food fish, are available at most of the larger communities along the waterway, including Atlantic City, Wildwood, and Cape May. The plants at the two latter places have direct railroad connections. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. A railroad bridge and a highway bridge across the Cape May Canal were operated and maintained throughout the year at a cost of $34,568.57. Cape May Canal was maintained with hired labor at a cost of $5,444.26. The cost of all work was $40,012.83 for maintenance. The expenditures were $41,382.14. Condition at end of fiscal year. The existing project was about 25 per cent complete. A canal 12 feet deep and 100 feet wide from Cape May Harbor to Delaware Bay was completed in 1942; two parallel stone jetties at the Delaware Bay entrance and one temporary highway drawbridge in 1943; and one temporary high- way drawbridge and one railroad bridge in 1944, all with Navy Department funds. The work remaining to be done is the dredg- ing of a channel 12 feet deep and 100 feet wide from the Atlantic Ocean at Manasquan Inlet to Cape May Harbor. The latest examination (September 1949) showed the controlling depth at mean low water in the canal connecting Cape May Harbor with Delaware Bay was 8.3 feet. The costs under the existing project, excluding $1,824,940 ex- pended for new work and $286,954.70 for maintenance from Navy Department funds and $99,000 contributed funds expended RIVERS AND HARBORS-PHILADELPHIA, PA., DISTRICT 307 for new work were $53,694.60 for new work and $257,600.09 for maintenance, a total of $311,294.69.

S. ARMY, 1951 Local cooperation. The River and Harbor Act of August 8, 1917, required that on all new work under the project approved by that act, except the channel into Curtis Bay, improvement by the United States is made conditional upon local interests provid- ing, whenever required by the Chief of Engineers, free of cost to the United States, suitable areas behind bulkheads or other revet- ment, satisfactory to the district engineer, in which the dredged material may be deposited. This condition has been met as far as the channel has been completed. The River and Harbor Act of July 3, 1930, provided for in- creased anchorage facilities subject to the provisions that no work shall be started on the area therein recommended until local in- terests have provided suitable disposal areas satisfactory to the district engineer alongside of bulkheads behind which said inter- ests will agree to pump the material without delay to the Govern- ment work; or, in lieu of the above requirement, agree to con- tribute the sum of 5 cents per cubic yard, scow measure, to cover the additional cost to the United States for disposal of the ma- terial on its own dumping area. This condition has been met. The River and Harbor Act of March 2, 1945, required that re- sponsible local interests agree to hold and save the United States free from claims for damage resulting from the work. This con- dition has been met in a resolution adopted by the city council of Baltimore and approved by the mayor on March 1, 1949. Terminal facilities. The total length of developed water front in Baltimore Harbor, measured along the established bulkhead line, is about 27 miles. Extensive areas remain which are available for further development. The existing terminal facilities include wharves, piers, grain elevators, coal and ore piers, storage and bunkering facilities for fuel oil, terminal warehouses, marine rail- ways, drydocks, and shipyards. The State legislature has authorized the city of Baltimore to incur an indebtedness of $50,000,000 for the development of the port.

POCOMOKE RIVER, MD. Location. This river is a tributary of Pocomoke Sound, an estuary of and on the easterly side of Chesapeake Bay about 40 miles north of Cape Charles, Va. Previous projects. The original project for Pocomoke River was adopted June 18, 1878, and modified by the River and Harbor Act of August 5, 1886. For further details see page 1789, An- nual Report for 1915, and page 385, Annual Report for 1938. 336 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Existing project. This provides for a channel 7 feet deep and 100 feet wide from that depth in Pocomoke Sound through "The Muds" to deep water in the river; and a channel 9 feet deep at mean low water and 100 to 130 feet wide from Shad Landing to above the bridge at Snow Hill, widened to 150 feet to form a turn- ing basin at the upper end, the length of the section included in the project being about 4.5 miles, the lower end of the section being about 25.7 miles above the mouth of the river. The mean range of tide is 2.5 feet and the extreme tidal range is 3.7 feet. The estimated Federal cost of new work, revised in 1951, is $179,900 exclusive of amounts expended under previous projects. The latest (1950) approved estimate of cost for annual mainte- nance is $21,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents June 3, 1896 A 9-foot channel from Shad Landing to Snow Hill Annual report for 1895, p. 1167. 1 Aug. 30, 1935 For a channel 7 feet deep and 100 feet wide from H.

Fully complied with except that local inter- ests are required to furnish releases from damage to oyster beds and spoil-disposal areas as required for future maintenance. Local interests are also required under the River and Harbor Act of March 2, 1945, to contribute one-half the initial cost of extend- ing the channel above the bridge at Snow Hill, but not to exceed $4,250; furnish free of cost to the United States, all lands, ease- ments, rights-of-way and spoil-disposal areas. Local interests are continuing their efforts to comply with these requirements. Terminal facilities. The present water fronts at Pocomoke City and at Snow Hill consist of pile and timber bulkheads with earth: fills. Some have warehouses and factories with mechanical handling facilities and rail sidings. Practically all are privately owned; most of them are in bad repair. Any appreciable increase in commerce at Pocomoke City would necessitate the construction of a new terminal and the repair of existing terminals. Consider- able land areas are available for the development of additional terminals if and when needed. Operations and results during fiscal year. None. There were no costs. Adjustments in total new work expenditures resulted in a decrease of $1.23. Conditions at end of fiscal year. The existing project is 90 percent complete. 'The work remaining to be done is the extension of the Channel to above the bridge at Snow Hill. The controlling depth was 9 feet, at mean low water, through "The Muds" to deep water in the river on east side of Williams Point, in mid-channel for half-project width, ascertained in October 1947 and July 1949, and, 9 feet.in the section in Pocomoke River from Shad Landing to Snow Hill, ascertained in March 1948. The condition RIVERS AND HARBORS--BALTIMORE, MD., DISTRICT 337 of the section above the bridge at Snow Hill is as contained in the project document. The total costs and expenditures were $341,630.57, of which $161,926.43 was for new work and $179,- 704.14 was for maintenance. Proposed operations.

There were six occasions when flood gates were operated on the various dams in order to reduce downstream flood crests. Two of the floods were of moderate intensity accruing substantial bene- fits to the reservoirs. The other four floods were too small to have caused appreciable damage. The most damaging flood oc- curred on November 24-26, 1950, but only Almond and Arkport Reservoirs were in the area of high run-off. Closing of the gates at Almond Reservoir, in conjunction with the retarding effect of the uncontrolled outlet on Arkport Reservoir, resulted in a substantial reduction of the flood crest along the Canisteo River. Heavy rains and the melting of snow from March 30 through April 2, 1951, caused minor floods throughout the upper Sus- quehanna River basin. Operation of gates at Whitney Point, East Sidney, and Almond Reservoirs along with the retarding effect of Arkport Reservoir were most effective in reducing flood dam- age. The total costs for the fiscal year were $948,994.31, of which $871,114.68 was for new work, and $77,879.63 was for main- tenance. The total expenditures were $1,079,902.63. Condition at end of fiscal year. The Southern New York project is approximately 50 percent complete, exclusive of the Genegantslet and South Plymouth Reservoirs, which are an ad- dition to the comprehensive program for Southern New York, authorized by the 1944 Flood Control Act, and described sepa- rately.

SMALL FLOOD CONTROL PROJECTS UNDER SECTION 205 OF THE FLOOD CONTROL ACT APPROVED JUNE 30, 1948, AS AMENDED Section 205 of the Flood Control Act approved June 30, 1948, as amended by section 212 of the Flood Control Act approved May 17, 1950, authorizes the allotment from flood control ap- propriations, not to exceed $3,000,000 for any one fiscal year, for the construction of small flood control projects not specifically authorized by Congress, and not within areas intended to be protected by projects so authorized, which come within the provisions of section 1 of the Flood Control Act of June 22, 1936, when in the opinion of the Chief of Engineers such work is advisable: Provided, That not more than $150,000 shall be allotted for this purpose at any single locality from the appropriations for any one fiscal year: Provided further, That the provisions of local cooperation specified in section 3 of the Flood Control Act of June 22, 1936, as amended, shall apply: And provided further, That the work shall be complete in itself and not commit the United States to any additional improvement to insure its suc- cessful operation, except as may result from the normal pro- cedure applying to projects authorized after submission of pre- liminary examination and survey reports. Pursuant to this Act, three projects were approved in this District. The first, on the Chenango River at Norwich, N. Y., provides for 9,000 feet of channel realinement and clearing through the town at an estimated Federal cost of $98,000. A second project at Greene, N. Y., provides for improvement of about 1,100 feet of Birdsall Creek below Birdsall Street by levee construction and rock protection at an estimated Federal cost of $43,500. The third, on Owego Creek at Owego, N. Y., provides for clear- ing the left bank of the Susquehanna River and an island in the river, clearing along the creek and improving sections of the creek channel at an estimated cost of $60,000. Local cooperation, see pages 4-5, requirements have been met on the first two projects and are expected to be furnished upon request for the third project. Operations and results during fiscal year. Channel relocation and clearing along the Chenango River at Norwich, N. Y., by contract, was continued and completed October 31, 1950. Con- struction of levees along Birdsall Creek at Greene, N.

Washington Harbor is located within the District of Columbia at the junction of the Anacostia River with the Potomac River which flows in a southeasterly direction 108 miles to the Chesapeake Bay. It is southerly 202 miles by water from Balti- 393 394 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 more, Md., and northerly 195 miles from Norfolk, Va., (See U. S. Coast and Geodetic Survey Chart No. 560.) Previous projects. 'The original project for the Potomac River was adopted by the River and Harbor Acts of March 2, 1833, July 11, 1870, and August 2, 1882. For further details, see page 1791 of Annual Report for 1915, and page 295 of Annual Report for 1934. The River and Harbor Act of September 19, 1890, author- ized an allotment for work on the Anacostia River; joint resolu- tion of Congress of April 11, 1898, made appropriation for a sur- vey; and a project was adopted by the River and Harbor Act of June 13, 1902 (H. Doc. 87, 55th Congress., 3d sess., and Annual Report for 1899, p. 1443). For further details see page 430 of Annual Report for 1932 and page 421 of Annual Report for 1938. Existing project. This project is a combination and extension of the latest projects for the Potomac River at Washington, D. C., and the Anacostia River, D. C. The project provides for: (1) Virginia Channel, from Giesboro Point to Francis Scott Key Bridge, 24 feet deep and 400 feet wide, with the width increased as necessary to afford a low-water cross-section area of 25,000 square feet; (2) Washington Channel, from Hains Point to the head of Washington Channel, 24 feet deep and 400 feet wide; (3) Anacostia River from Giesboro Point to Anacostia Bridge, 24 feet deep and 400 feet wide, with turning basin 800 feet wide and approximately 2,400 feet long of same depth opposite the Naval Gun Factory; (4) Anacostia River from Anacostia Bridge, 24 feet deep and 200 feet wide to turning basin 400 feet square of same depth at foot of Fifteenth Street SE. The channel lengths including turning basins are: Virginia Channel, 25,000 feet; Washington Channel, 10,000 feet; and Anacostia River, 15,000 feet. (5) operation and maintenance of the inlet gates and lock and the outlet gates of the Tidal Basin constructed under a previ- ous project to flush the Washington Channel. The plane of ref- erence is low-water datum which is 0.35 foot below mean low tide as observed from 1932 to 1942. Tidal ranges are: Mean, 2.9; irregular, 4.5; and extreme, 10.7. The estimate of cost to the Federal Government for new work, revised in 1951, is $558,000 exclusive of amounts expended under previous projects. The latest (1950) approved estimate for an- nual cost of maintenance is $83,000. The existing project was adopted by the River and Harbor Act of August 30, 1935 (Rivers and Harbors Committee Doc. 22, 74th Cong., 1st sess.). The latest published maps are in the project document. Terminal facilities. On the Virginia Channel (Georgetown water front) there are 10 wharves generally of the bulkhead type, of timber, stone, and concrete, privately owned. Railroad and crane service are available at a number of the wharves. On the Washington Channel are 2 yacht basins with a total capacity for 198 yachts, under jurisdiction of the District of Columbia and 12 wharves of open pile and bulkhead construction, all owned by the Federal Government, but most of which are leased to private parties or serve governmental agencies. On the Anacostia River RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 395 are about 23/4 miles of commercial water front on which are located 7 privately owned and 2 Government wharves, and 3,500 linear feet of bulkhead with slips for governmental agencies. In addition, there are numerous small stagings and floats used by yacht clubs for mooring small boats. Some of the wharves and slips have transfer and rail facilities. The wharves of the Wash- ington Harbor are only open to the public by special arrange- ment, except for the District of Columbia fish wharves on the Washington Channel. 'Terminal facilities, except for those in the Washington Chan- nel, are considered adequate for existing commerce. Operations and results during fiscal year. The Tidal Basin gates were repaired and operated by hired labor throughout the year at a cost of $9,782.37, A hydrographic survey of the dumping area at Daingerfield Island was completed by Government plant and hired labor at a cost of $351.93. Total costs for the year were $10,134.30, all for maintenance. Total expenditures were $8,691.72. Condition at end of fiscal year. The existing project was started in April 1937 and was about 50 percent complete at the end of the fiscal year. The channels and basins in the Anacostia River are complete and those at the forks of the channel at Hains Point are partially complete. Except for dredging between the limits of 2,000 feet above and 3,000 feet below the Memorial Bridge, no new work has been done downstream of Key Bridge in Virginia Channel. The controlling depths in the channels throughout the harbor were as follows: Controlling Name of channel Depth Date Potomac River, Virginia Channel from Glesboro Point to Key Bridge-_ 20.3 feet 1-- - April 1949.

The work remaining to be done to complete the project consists of: (1) Removal of rock in Virginia Channel upstream of Me- morial Bridge. (2) Dredging in Virginia Channel from Giesboro Point up- stream to a point 3,000 feet below Memorial Bridge. Total costs for the existing project were $855,578.27, of which $162,006.33 was for new work and $693,571.94 was for main- tenance. This is exclusive of $4,000 for emergency dredging under provisions of Section 3 of the River and Harbor Act of March 2, 1945. The total expenditures were $854,072.31. Proposed operations. The balance unexpended June 30, 1951, $1,505.96 plus an allotment of $12,500.00 made for fiscal year 1952, a total of $14,005.96, will .be applied as follows: 396 REPORT OF CHIEF OF ENGINEERS, U. S.

POTOMAC RIVER, NORTH SIDE OF WASHINGTON CHANNEL, D. C. Location. The area covered by the project is the waterfront channelward of Maine Avenue on the north side of Washington Channel, extending upstream from Fort Leslie J. McNair (War College) at Maine Avenue and P Street a distance of approxi- mately 5,123 feet to the foot of Fourteenth Street SW., in the District of Columbia. (See U. S. Coast and Geodetic Survey Chart No. 560.) Existing project. This provides for development of the com- mercial water front of Washington Channel by construction of (1) a yacht harbor in four sections on the upstream half of the section, with berthing space for about 286 boats; (2) two wharves for activities of the District of Columbia; (3) three wharves for existing transportation lines and general service; (4) construc- tion of bulkhead walls; and (5) removal of the old and dilapidated existing structures. The project further provides that during the construction period the District Engineer be given jurisdiction over the entire waterfront except the municipal fish wharf, and that the completed work as well as the maintenance and ad- ministration thereof should be under the Commissioners of the District of Columbia. The estimate of cost to the Federal Government for new work, revised in 1951, is $6,461,200 exclusive of $389,000 to be con- tributed by the District of Columbia to cover the cost of the two RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 397 wharves for District of Columbia activities. The latest (1950) approved estimate for annual cost of maintenance is $1,600. The existing project was adopted by the River and Harbor Act of August 30, 1935 (Rivers and Harbors Committee Doc. 13, 73d Cong., 1st sess.). Detailed plans approved by the Chief of Engineers, September 24, 1945, provide for the following modifications in the items of construction: (1) A yacht harbor in three sections on the up- stream half of the water front with berthing space for about 356 boats; (2) one wharf for the combined use of the police and fire departments of the District of Columbia; (3) three wharves for existing transportation lines and general service; (4) construc- tion of bulkhead walls; and (5) removal of the old and dilapidated existing structures. Local cooperation. Fully complied with. Terminal facilities. The entire water front is Government- owned and facilities are leased to individuals or serve govern- mental agencies. Two yacht basins to accommodate 198 yachts and small boats together with a public sales and service pier, a concrete pier 340 feet long and 100 feet wide for general com- mercial use and a concrete pier 340 feet long and 75 feet wide for use by excursion boats have been completed under the existing project. Of the 12 commercial piers only 5 can be classed as modern. The only wharves open to the public are those owned by the District of Columbia at the municipal fish market where daily rental rates are charged. The facilities are considered inadequate for existing commerce. Operations and results during fiscal year. Construction by contract of the superstructure of the excursion pier (pier 4) was in progress at the beginning of the fiscal year and the struc- ture was completed on March 5, 1951, at a cost for the year of $300,601.64. Demolition by contract of a dilapidated building on the site of pier 3 was started in May and completed in June 1951 at a cost of $422.25. Costs of miscellaneous surveys and general studies made throughout the year were $856. The cost for removal of a temporary field office and restoration of the site was $207.50 all chargeable to new work. Unimproved properties not required for construction were leased for private use at a cost for the year of $997.86 chargeable to maintenance. Total costs for the fiscal year were $303,085.25, of whichl $302,087.39 was for new work and $997.86 was for maintenance, all United States funds. Total expenditures were $327,310.95, United States funds. Condition at end of fiscal year. The existing project was started in April 1938 and was approximately 35 percent com- plete at the end of the fiscal year. Construction of Yacht Basins Nos. 1 and 2 was completed in November 1940 and the basins were leased for commercial use and transferred to the District of Columbia for operation and maintenance on December 3, 1940. Commercial pier No. 5 was completed in December 1941 and was transferred to the District of Columbia for operation and main- tenance on March 21, 1942. The excursion pier (pier 4) was com- 398 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 pleted in March 1951 and was tiansferred to the District of Columbia for operation and maintenance on April 25, 1951. Plans and specifications for Yacht Basin No. 3 were 75 percent com- plete, and for piers No. 2 and No. 3, were 7 percent complete. The work remaining to be done to complete the project consists of (1) construction of two yacht basins; (2) construction of two piers for activities of the District of Columbia; (3) construction of a pier for existing transportation lines and general service; (4) completion of bulkhead walls; and (5) completion of re- moval of existing structures. Total costs were $1,747,848.29, of which $1,741,693.01 was for new work and $6,155.28 was for maintenance. In addition, $389,- 000 from contributed funds was expended for new work.

The waterchestnut, botanically known as Trapa natans, is an annual fresh-water plant infesting the navigable portions of the Potomac River and its tributaries between Key Bridge in the District of Columbia and Maryland Point, 48 miles downstream of Washington, D. C. Washington, D. C., is located 108 miles upstream of the mouth of the river. At the height of infestation in 1939, it covered about 10,000 acres of navigable waters between these limits. (See U. S. Coast and Geodetic Sur- vey Charts Nos. 559 and 560.) Existing project. This provides a plan for complete eradica- tion of the waterchestnut from the Potomac River and its tribu- taries at and below Washington, D. C., by (a) 4 years of mechani- cal cutting in heavily infested areas with manual removal of scattered plants; (b) 3 years of intensive patrol and manual re- moval of scattered plants; (c) 2 years of concentrated patrol during the growing season; (d) 6 years of patrolling the entire area every 2 years. The tidal ranges are: Mean, 1.1 feet at Mary- land Point and 2.9 feet at Washington; irregular, 2 feet at Mary- land Point and 4.5 feet at Washington; extreme, approximately 7.5 feet at Maryland Point and 10.7 feet at Washington. The estimate of cost to the Federal Government, made in 1947, was $142,000, which is the total of annual costs over a 15-year period, decreasing from $32,000 during the first year to $3,500 for the ninth year and an average of $1,000 for each of the six years thereafter. This is an average of $9,467 annually for the 15 years. If a longer period is required, the average annual cost for each subsequent year is estimated to be $1,000. The work is maintenance. The existing project was authorized by the River and Harbor Act approved May 17, 1950 (H. Doc. 113, 81st Cong., 1st sess.). The latest published map is in the project document. 402 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Operations and results during fiscal year.

C., by Government plant and hired labor at a cost of $17,- 488.13. The cost for the year was $17,488.13 for maintenance. Expend- itures were $10,318.51. Condition at end of fiscal year. Work on the elimination of waterchestnuts has been in progress since 1939 under allotments for maintenance of five existing river and harbor projects. Prior to the adoption of this project and through the fiscal year ending June 30, 1950, a total of 25,000 acres of the growth has been cut and recut from the Potomac River and its tributaries between Washington, D. C., and Maryland Point. All infested areas have been cut at least once. Two years of mechanical cutting in heavily infested areas and manual removal of scattered plants as listed for accomplishment under the eradication schedule for the exist- ing project have been completed under maintenance of other existing river and harbor projects prior to adoption of the eradi- cation project. Prior to the adoption of the project and through the fiscal year ending June 30, 1950, maintenance funds in the amount of $310,- 187.08 were expended for removal of waterchestnuts. This amount includes $10,000 allotted under section 3 of the River and Harbor Act of July 3, 1930, and $10,000 allotted under section 3 of the River and Harbor Act of October 17, 1940, to 10 tribu- taries of the Potomac River, and the following maintenance funds from existing river and harbor projects in the affected area: Washington Harbor, D.

URBANNA CREEK, VA. Location. Urbanna Creek rises in Virginia and flows in an easterly direction about 5 miles to the Rappahannock River, which 406 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 it enters about 15 miles above its mouth. The creek is 76 miles northerly of Norfolk, Va. (See U. S. Coast and Geodetic Survey Chart No. 535.) Existing project. This provides for dredging a channel 150 feet wide and 10 feet deep from deep water in the Rappahannock River to Burtons wharf, a distance of 4,675 feet, including a turning basin of the same depth approximately 400 feet wide and 1,575 feet long between the Standard Oil wharf and Burtons wharf, and for jetties to protect the channel through the outer bar. The jetties are 2,612 feet long-one of riprap, 1,895 feet long and one of timber 717 feet long. The plane of reference is mean low water. The tidal ranges are: Mean, 1.6 feet; irregular, 2.5 feet; and extreme, 7.8 -feet. The estimate of cost to the Federal Government for new work, revised in 1951, was $55,000, exclusive of amounts expended under previous projects. The latest (1950) approved estimate for an- nual cost of maintenance is $1,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents and reports [Channel 10 feet deep and 150 feet wide through bar Annual Report, 1875, pt. 2, p. 139 at entrance.

Modification of the project in 1945 was ap- proved subject to the conditions that local interests furnish spoil- disposal areas as and when required and hold and save the United States free from claims for damages resulting from the work and subsequent maintenance. It is expected that these requirements will be met promptly. Operations and results during fiscal year. None. An adjust- ment of minus 19 cents to previously reported maintenance costs was made. Expenditures were $160.59 for payment of outstand- ing liabilities. Terminal facilities. This waterway has 11 improved wharves of open pile construction, and a marine railway. There are several shore landings intermittently used by craft for embarking lumber and there are several small wharves used for private purposes and of no commercial importance. These facilities are considered adequate for existing commerce. Condition at end of fiscal year. The project prior to the 1945 modification was started in October 1879 and was completed in January 1914. The jetties were completed in August 1913 and the dredging in January 1914. The stone jetty is in good condi- tion; the timber dike has been partially destroyed. No work has been done on the modified project. The controlling depth in May 1950 was 8.3 feet at mean low water at a point approxi- mately 400 feet downstream of the steamboat wharf. The total costs under the existing project were $85,633.54, of which $38,- RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 407 811.77 was for new work and $46,821.77 was for maintenance.

CARTERS CREEK, VA. Location. The creek is a small tidal estuary with three prongs in Lancaster County, Va., 2 miles long, flowing southwesterly and entering the Rappahannock River on the left bank, 10 miles up- stream of the mouth. The creek is 70 miles northerly from Nor- folk, Va. (See U. S. Coast and Geodetic Survey Chart No. 534.) Existing project. This provides for an entrance channel 15 feet deep, 200 feet wide, and about 2,200 feet long across the entrance bar; a channel in Eastern Branch at Gallyhook Point 12 feet deep, 100 feet wide, and 1,100 feet long; and in Carters Cove a channel 12 feet deep, 100 feet wide, and 1,700 feet long to the Humphreys Marine Railways, Inc.; and for a jetty 742 feet long on the downstream side of the entrance channel. The plane of reference is mean low water. The tidal ranges are: Mean, 1.4 feet; irregular 2.5 feet; and extreme, 7.8 feet. The estimate of cost to the Federal Government for new work, revised in 1951, is $51,600, exclusive of $4,000 to be contributed by local interests. The latest (1950) approved estimate for annual cost of maintenance of the channel in Carters Cove is $1,000. There is no approved estimate of maintenance for the other por- tions of the project.

ARMY, 1951 tribute $4,000 for the cost of the work. This condition has not been complied with and compliance is not expected in the near future. Terminal facilities. There are 11 wharves on the creek, all of timber construction. All of the wharves are privately owned and open to the public by special arrangement. The existing wharf facilities are considered adequate. Operations and results during fiscal year. A hydrographic survey made during the preceding fiscal year was completed in August 1950 at a cost of $30.87 applied to maintenance. Expendi- tures were $157.43. Condition at end of fiscal year. The entrance channel and Gallyhook Point Channel in Eastern Branch were started in Octo- ber 1904 and were completed in April 1908 and the jetty was completed in March 1906. Work has not been commenced on the new channel in Carters Cove, authorized by the River and Harbor Act of July 3, 1930. The project is 73 percent complete. The controlling depth at mean low water in the entrance channel was 15.4 feet, May 1950; in the Gallyhook Channel, 13.5 feet, May 1950; and in Carters Cove, 8.7 feet in May 1950. The total costs under the existing project were $31,573.26, of which $28,397.55 was for new work and $3,175.71 was for main- tenance, which includes $1,000 for emergency dredging in Carters Cove, under provision of section 3 of the River and Harbor Act of July 3, 1930. The total expenditures were $31,573.26. In addi- tion $700 contributed funds was expended for maintenance. Proposed operations. No work is scheduled for the fiscal years 1952 or 1953 as it is believed that maintenance will not be neces- sary.

MAINTENANCE, OPERATION, AND CAPITAL OUTLAY OF THE WASHINGTON AQUEDUCT Location. The diversion dam and raw-water intakes are lo- cated on the Potomac River at Great Falls 131/2 miles northwest of Washington, D. C.; the two collecting conduits, part of the RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 409 Dalecarlia receiving reservoir, and the booster pumping plant that lifts the water from the forebay to the main body of the Dalecarlia Reservoir are located in Maryland; and all other structures of the water-supply system including part of the raw- water collecting system, the purification plants, pumping sta- tions, storage reservoir, and transmission mains are located in the District of Columbia, (See U. S. Geological quadrangle, Washington and vicinity.) The control of the water-supply system is vested in the Chief of Engineers. (See acts of March 3, 1859, and March 2, 1867, and sec. 1800 of Revised Statutes.) Existing project. The existing project provides for (a) opera- tion, maintenance, repair, and protection of the water-supply facilities and reservations including collection, treatment, purifi- cation, pumping, transmission, and storage facilities; MacArthur Boulevard; and meters on all Federal water services as author- ized by law and (b) the planning and construction of increased supply facilities in accordance with House Document 480, Seven- ty-ninth Congress, dated August 15, 1945, as provided in Public Law 538, Eighty-first Congress, chapter 218, second session, H. R. 8578, approved June 2, 1950. By act, Public Law 378, Sixty-fourth Congress, approved March 3, 1917, the furnishing of water to adjacent Maryland areas from the Washington water-supply system was authorized by the Congress; by act, Public Law 119, Sixty-ninth Congress, ap- proved April 14, 1926, the furnishing of water to Arlington County, Va., from the Washington water-supply system was authorized by the Congress; and, by act, Public Law 118, Eighti- eth Congress, approved June 26, 1947, the furnishing of water to Falls Church or any other competent State or local authority in the Virginia metropolitan area, similarly, was authorized. A description of the District of Columbia water-supply system and of previous capital-improvement and operation-and-mainte- nance projects is printed on pages 2206-2208 and 2218-2220 of the Annual Report of the Chief of Engineers, 1930; in an in- formation pamphlet published June 1939 and revised December 1950; and in House Document 480, Seventy-ninth Congress. Local cooperation. Prior to July 1, 1880, the expenses of the Washington Aqueduct for construction, operation, and mainte- nance were paid wholly out of the revenues of the United States. From July 1, 1880, to July 1, 1916, the expenses of construction, operation, and maintenance were paid one-half by the United States and the other half out of the general revenues of the Dis- trict of Columbia. From July 1, 1916, to June 30, 1924, the expenses of construction were paid 60 percent out of the general revenues of the District of Columbia and 40 percent by the United States. From July 1, 1924, to June 30, 1927, expenses of construction of the Washington Aqueduct were paid wholly out of the general revenues of the District of Columbia to which the United States contributed annually a lump sum. The expenses of operation and maintenance, since July 1, 1916, to date, have been paid wholly out of the water revenues of the District of 410 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Columbia. From July 1, 1927, to date, all expenses for construc- tion have been paid out of the water revenues of the District of Columbia. By act approved June 10, 1920, $25,000 was appropriated wholly from United States revenues to prepare, among other things, a report to assure an increased and adequate water supply for the District of Columbia and this report was the basis for the im- provements constructed from 1922 to 1927. Included in the Dis- trict of Columbia appropriation acts of 1941 and 1942, approved June 12, 1940, and July 1, 1941, respectively, a total of $40,000 was appropriated from the water fund, District of Columbia, for the preparation of a report "for the development of a plan to insure an adequate future water supply for the District of Colum- bia and metropolitan area." This report, published as House Document 480, Seventy-ninth Congress, contains the comprehen- sive plan and program for the improvements and additions to the water system safely and adequately to meet the anticipated water demands to the year 2000. Annually, since July 1, 1916, on a percentage basis, and since July 1, 1924, on a lump-sum basis, the United States has contrib- uted to the support of the District of Columbia but no part of such annual percentage or lump-sum contributions has been allocated to the water fund, District of Columbia, before July 1, 1947. Beginning with the fiscal year 1948, pursuant to act, Public Law 195, Eightieth Congress, approved July 16, 1947, an annual payment of $1,000,000 was authorized for water consumed by the Federal Government. This sum is taken from the annual lump sum contribution of the United States to the District of Columbia. Act, Public Law 533, Eighty-first Congress, chapter 218, H. R. 8578, approved June 2, 1950, authorized the Secretary of the Treasury to lend with a limit of $23,000,000 to the Commissioners of the District of Columbia such sums as may hereafter be appro- priated to finance expansion and improvement of the water sys- tem when sufficient funds therefor are not available from the District of Columbia water fund established by law (D. C. Code, 1940 edition, title 1943, ch. 15). Operations and results during the fiscal year. An uninter- rupted and adequate supply of purified water was furnished to the District of Columbia; to Arlington County, Va.; and to Fed- eral establishments in Arlington County, Va., and in Montgomery and Prince Georges Counties, Md. The maximum daily consump- tion was 214,559,000 gallons and the average daily consumption was 165,058,383 gallons. Based upon the estimated average num- ber of consumers of 935,000 in the District of Columbia and 150,- 000 in Arlington County, the average per capita daily consumption was 152.13 gallons. The average daily consumption in the District of Columbia alone was 149,620,277 gallons or an average per capita consumption of 160.02 gallons per day. The average daily amount of water furnished to Arlington County and Falls Church, Va., was 12,721,178 gallons or an average per capita consumption RIVERS AND HARBORS-WASHINGTON, D. C., DISTRICT 411 of 84.81 gallons per day. The gross cost for the supply furnished the Virginia communities was reimbursed to the water fund, District of Columbia. The average daily consumption of water in all Federal Government establishments, including parks, zoo- logical garden, etc., was 28,179,052 gallons. A total of 99"1,679,000 gallons or an average of 2,716,928 gallons per day was delivered to Maryland communities during the fiscal year 1951 by the Water Division, District of Columbia, through connections to the Washington Suburban Sanitary District's system. The average turbidity of the raw water from the Potomac River was reduced from 191 parts per million to 0.00 parts per million and the average bacterial content was reduced from 3,046 to 1.2 per milliliter. Analyses were made for bacterium colon on 91,222 tubes of water taken from 135 sampling points in the purification and distribution systems. After sterilization of the filter effluent, the average number of bacterium colon per 100 milliliters was found to be 0.02 at Dalecarlia and 0.08 at the McMillan filter plant. The average alkalinity of the filtered water was 54 parts per million and the average pH value was 7.7 parts per million from the Dalecarlia filter plant and 7.4 from the McMillan filter plant. The average hardness was 98 parts per million from Dalecarlia and 91 parts per million from McMillan. The direct operating costs of water treated and delivered to the system per million gallons was $26.24 as compared with the cost of $23.24 per million gallons in fiscal year 1950. The over-all cost of water delivered, including depreciation and interest, was $51.17 per million gallons as compared with $46.04 in 1950. Construction work authorized with "no year" funds, not pre- viously reported as completed, was as follows: Repair and rehabilitation of McMillan filter plant 100 percent; McMillan Filter Plant improvements, 100 percent; utility reloca- tions, Dalecarlia, 100 percent; conduit repairs, (periodic) 94 percent; flocculation equipment for existing coagulation basins, 100 percent; purchase and installation of Federal meters (peri- odic) 51 percent; circulating facilities in first and second high- service reservoirs, 99 percent; remodeling of Georgetown Reser- voir, 95 percent; and acquisition of supplementary land, 9 percent. Thirty-million-gallon clear-water basin, 2 percent; six filters at Dalecarlia, 91 percent; extension of engineering office space, 18 percent; improving conveying equipment, 23 percent. The preparation of plans for capital outlay projects for in- creasing the water supply progressed as follows: Thirty-million-gallon clear-water basin at Dalecarlia, 75 per- cent; reservoir at Fort Reno (first half), 95 percent; 11/2 -million- gallon Reno water tower, 30 percent; fourth high-service pump- ing station at Reno, 10 percent; 48-inch pipeline from Dalecarlia to Reno, 65 percent; crosstown interconnecting main from Dale- carlia to low-service area (first half) 8 percent; McMillan filter plant improvements, 95 percent; new chemical building and oper- ating center at McMillan, 10 percent utility relocations at Dale- carlia (periodic) 100 percent; Georgetown reservoir improve- ments, 95 percent; Dalecarlia pumping station, 15 percent; office 412 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 extension, 95 percent; six filters addition to Dalecarlia, 100 per- cent; collector mains at McMillan, 100 percent; Little Falls drain- age channel, 40 percent; Great Falls intake structure, 5 percent; shops and storehouse at Dalecarlia, 100 percent; Federal meters, 50 percent; land acquisitions, 20 percent; and conduit repairs, 40 percent.

C., DISTRICT 413 Control: All funds were expended in conformity with the leg- islative provision contained in the annual appropriation act which was as follows: Nothing herein shall be construed as affecting the superintendence and control of the Secretary of the Army over the Washington Aqueduct, its rights, appurtenances, and fixtures connected with the same and over appropriations and expenditures therefor as now provided by law. Condition at end of fiscal year. The intakes, conduits, reser- voirs, filter plants, pumping stations, mechanical equipment, and structures with the exception of the McMillan filter structures on which repairs are in progress were in a generally good con- dition. However, the demands upon the supply system have ex- ceeded its nominal capacity and, for several years, its operation has been in the overload category. During maximum consump- tion demand periods, the basic raw water supply was exceeded and emergency equipment had to be utilized.

The Anacostia River enters the Potomac River at Washington, D. C. Previous projects. For the part of the project below the Ana- costia Bridge, which is also a river and harbor improvement, see Annual Report of the Chief of Engineers for 1919, page 553, under heading "Existing project." For a description of the previous projects for the improvement extending upstream from the Anacostia Bridge see Annual Report of the Chief of Engi- neers for 1923, page 1990 under heading "Existing project." Existing project. This provides for the improvement of the river and for the reclamation and development of the adjacent flats from the mouth of the river upstream to the District of Columbia boundary line, a distance of about 6/3 miles, to afford a river channel 15 feet deep in the section between the foot of Fifteenth Street SE., and Massachusetts Avenue, 9 feet deep thence to Benning Road. The section from the mouth upstream to the foot of Fifteenth Street SE., was dredged to a depth of 24 feet under a river and harbor project. The dredged material is to be used for fills. The project includes a constant-level lake or lateral basin on the west side of the river, to be known as Lake Kingman, and a smaller lake on the east side of the stream. The normal surface elevation of the lakes is to be 2 feet above mean low tide, and they are to be dredged to a depth of 6 feet. A culvert or small bridge is to be constructed over Lake Kingman on the line of Benning Road, and a lock and bridge is to be built at the lower end of Lake Kingman. Influent and effluent gate-control works are to be constructed to provide circulation and maintain a con- stant level in both lakes. Masonry sea walls on a riprap substructure are to be con- structed along the tidal channel of the river to extend 6 feet above mean lowwater; the walls of the lakes are to extend 3 feet above mean lowwater or 1 foot above the level of the lake. A portion of the reclaimed tract is to be set aside for develop- ment by the Agriculture Department for a national arboretum and botanical garden. A strip of water-front land on the right bank of the river between the Anacostia Bridge and the Pennsyl- vania Railroad freight bridge is to be set aside for commercial purposes. The estimated cost of the project is $6,570,000, revised in 1951. To this must be added $150,000 appropriated by act approved July 3, 1930, and $15,000 appropriated by act approved April 4, 1938, for cost of land not covered in estimated cost of project because of increased commercial valuation and subsequent adverse court decision as to United States ownership. The acts of Congress authorizing and defining the present plan of improvement are as follows: 416 REPORT OF CHIEF OF ENGINEERS, U. S.

The latest published map is found in Annual Report of Chief of Engineers, 1924, at page 1994. The District of Columbia Appropriation Act approved March 2, 1911, 36 Stat. 1005 (Public No. 44), in authorizing the project provided that the work is to be carried on under the supervision of the Chief of Engineers, United States Army, upon plans pre- pared under the direction of, and to be approved by, a board of engineers to consist of the Engineer Commissioner of the District of Columbia, the officer in charge of public buildings and grounds, and the engineer officer in charge of the improvements of the Potomac River. Executive Order No. 6166, dated June 10, 1933, transferred the functions of the Office of Public Buildings and Grounds to the Na- tional Park Service, Department of Interior. Accordingly, the Director of the National Park Service has become a member of the board of engineers in lieu of the officer in charge of public buildings and grounds. Local cooperation. The funds for this project have been ap- propriated by the District of Columbia appropriation bills, which through the fiscal year ended June 30, 1920, provided for half, of the expense to be borne by the District of Columbia. From that date to June 30, 1924, the expense was borne 60 percent by the District of Columbia and 40 percent by the United States. Be- ginning July 1, 1924, the District of Columbia paid all required above the lump sum appropriated from United States revenues. Operations and results during fiscal year. None. Construction work on the project was deferred in 1941 as a result of the war, and has not been resumed due to lack of appropriations. Expenditures, all for new work, were $170.34, applied to pay- ment of outstanding liabilities. Condition at end of fiscal year. The existing project is 70 per- cent completed.

SALEM CHURCH RESERVOIR, VA. Location. The Salem Church multiple-purpose reservoir to be located on the Rappahannock and Rapidan Rivers in Culpeper and Orange Counties, Va., would be created by a concrete gravity dam on the Rappahannock River, 5.6 miles above Fredericks- burg, Va., and 113 miles above the mouth. (See Army Map Serv- ice quadrangle, Salem Church, Va., and U. S. Geological Survey quadrangle, Spotsylvania, Va.) Existing project. The plan of improvement provides for con- struction of a concrete gravity dam, approximately 1,300 feet long, with a maximum height of 208 feet above bedrock, and earth embankments extending from both abutments, totaling 16,000 feet in length, with a maximum height at the left abutment FLOOD CONTROL--WASHINGTON, D. C., DISTRICT 427 of 63 feet. The spillway would consist of 2 sections, 1 of 15 crest gates, 30 feet wide by 25 feet high, located in the gravity section, and the other of five 50- by 53.5-foot fixed-wheel gates located in the bedrock of the right abutment. The spillway channel curves toward and enters the river 650 feet below the dam. The total discharge capacity of the spillway would be 545,000 cubic feet per second. The project provides for a power plant, to be con- structed integral with the dam at the left side of the river chan- nel, containing two 27,250-kilowatt generating units with provision for additional installation. The reservoir will afford flood protection for Fredericksburg, Falmouth, and areas down- stream for a flood of approximately 200,000 cubic feet per second. Estimated cost of the project to the Federal Government, revised in 1951, is $39,400,000, of which $5,950,000 would be for lands and damages. Authorization for the project is contained in the Flood Control Act approved July 24, 1946, which stipulated that the maximum elevation of the power pool should not exceed ele- vation 220 feet mean sea level.

This river, a tidal stream, rises in Accomac County, Va., flows in a westerly direction about 6.5 miles and empties into Chesapeake Bay. The portion under improvement extends from the mouth of the river to Onancock, Va., a distance of about 5 miles which is the approximate length of the tidal reach. (See U. S. Coast and Geodetic Survey Chart No. 1223.) Previous projects. The original project was adopted by the River and Harbor Act of March 3, 1879, and was modified by the River and Harbor Act of September 19, 1890. The modified proj- ect was superseded by a project adopted by the River and Harbor Act of June 25, 1910, work under which was completed in 1911. For further details see page 1799 of Annual Report for 1915, page 493 of Annual Report for 1924, and page 388 of Annual Report for 1938. Existing project. This provides for a channel 12 feet deep at mean low water, 200 feet wide across the bar, a distance of 5,200 feet, and generally 100 feet wide in the river to a point roughly 1,200 feet above the mouth of the North Branch, widened at the upper end to form a basin 200 feet square; and a turning basin about 2.3 acres in area at Onancock. It also provides for a chan- nel 6 feet deep and 100 feet wide in the lower 500 feet of Joynes Branch and an anchorage basin 6 feet deep and 3.9 acres in area at the mouth of Titlow Creek. Under ordinary conditions the mean tidal range is 1.7 feet and the extremes are 1.5 and 2 feet. The cost for new work for the completed project was $154,365, exclusive of amounts expended on previous projects. The latest (1950) approved estimate for annual cost of maintenance is $6,500.

The River and Harbor Act of March 2, 1945, in adopting the present project dimensions, imposed the conditions that local interests agree to furnish suitable areas for disposal of dredged spoil for new work and subsequent mainte- nance when and as required, to provide suitable terminal facilities open to all on equal terms, and to hold and save the United States free from claims for damages resulting from the improvement. These conditions have not been complied with. Terminal facilities. There are three timber wharves on this stream with an available frontage of about 100 linear feet each. The wharfage facilities are believed to be adequate for the exist- ing commerce on the creek. Operations and results during fiscal year. Preliminary office work in connection with a proposed condition survey was carried on during the year at a cost and expenditure of $82.76, all for maintenance. Condition at end of fiscal year. The existing project was about 27 percent complete at the end of the fiscal year. Construction of the channel across the bar at the mouth was commenced in August 1931 and completed in October 1931.

QUINBY CREEK, VA. Location. This creek is an indeterminate natural channel on the Atlantic Ocean side of the Delmarva Peninsula about 32 miles north of Cape Charles and about 33 miles south of Chincoteague, Va. The creek extends in a generally southeasterly direction be- tween Quinby Landing at Quinby, Va., and the head of Tony's Rock Drain, a distance of 6,900 feet. (See U. S. Coast and Geo- detic Survey Chart No. 1221.) Existing project. This provides for a channel 8 feet deep at mean low water and 80 feet wide from that depth in Upshurs Bay to a point 600 feet bayward from Quinby Landing, thence 60 feet wide from Quinby Landing, a total distance of about 6,900 feet, and a turning and mooring basin of the same depth, 200 feet wide and 400 feet long opposite the public terminal and landing. The mean range of lunar tides is 4.4 feet with variations caused by storms of from 2 feet below to 12 feet above mean low water. The estimate of cost for new work, revised in 1951, was $123,- 000. The latest (1950) approved estimate for annual cost of maintenance is $6,000. The existing project was adopted by the River and Harbor Act of May 17, 1950 (H. Doc. 241, 81st Cong., 1st sess.). The latest published map is in that document. Local cooperation. The River and Harbor Act of May 17, 1950, in adopting the existing project, imposed the conditions that 440 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 responsible local interests give assurances satisfactory to the Secretary of the Army that they will (a) provide without cost to the United States all lands, easements, rights-of-way, and spoil- disposal areas for construction and subsequent maintenance of the project, when and as required; (b) hold and save the United States free from damage due to the construction and maintenance of the project, including such damage as may occur to public or leased oyster and clam beds; (c) provide at their own expense suitable mooring facilities within the basin and terminal facilities adjacent thereto with suitable access road and parking area all of which shall be open to all on equal terms; and (d) establish and enforce suitable regulations governing the movement and an- chorage of craft in the vicinity of the improvement. These condi- tions will be complied with in the near future. Terminal facilities. There are two open-pile wooden wharves and about 125 feet of wooden bulkhead at Quinby, Va. The wharves are privately owned but the bulkhead is public and is open to all on equal terms. There is also one marine railway which is not now in use. With the construction of the facilities required of local interests, it is considered that these facilities will be adequate for existing and reasonably prospective com- merce. Operations and results during fiscal year. None. Condition at end of fiscal year. No work has been accomp- lished on the project. The controlling depths at mean low water, as ascertained in February, 1949, are 0.4 foot in the channel and +3.8 feet in the turning basin area. The head of navigation for boat traffic is Quinby Landing at Quinby, Va. Navigation is practicable throughout the year. The work remaining to be done to complete the project consists of dredging a channel 8 feet deep at mean low water and 80 feet wide from that depth in Upshurs Bay to a point 600 feet bayward from Quinby Landing, thence 60 feet wide to Quinby Landing, a total distance of about 6,900 feet, and a turning and mooring basin of the same depth, 200 feet wide and 400 feet long opposite the public terminal and landing.

OYSTER CHANNEL, VA. Location. Oyster Channel is located on the lower eastern side of the Delmarva Peninsula which separates Chesapeake Bay from the Atlantic Ocean. It is about 11 miles north of Cape Charles and about 57 miles south along the Atlantic coast from the Vir- ginia-Maryland State line. (See U. S. Coast and Geodetic Survey Chart No. 1222.) Existing project. This provides for a channel, about 0.9 mile long, 60 feet wide, and 6 feet deep at mean low water, from deep water in Liscombes Channel to and including a turning basin of the same depth 200 feet long and 125 feet wide along the water front at Oyster, Va. The mean range of tide is about 4.4 feet. Greater fluctuations in water level are caused by prolonged high winds along this section of the Atlantic coast. The cost for new work for the completed project was $54,600. The latest (1950) approved estimate for annual cost of mainte- nance is $1,000. The existing project was adopted by the River and Harbor Act of March 2, 1945 (H. Doc. 716, 76th Cong., 3d sess.). The latest published map is in the project document. Local cooperation. Fully complied with as to initial construc- tion. Local interests are required to furnish suitable spoil-disposal areas for future maintenance. Terminal facilities. There are five privately owned timber wharves and one publicly owned wooden bulkhead with a total wharfage space of about 1,100 feet along the water front at Oyster, Va. There is also a marine railway which will accomo- date vessels up to 50 feet in length. The facilities have highway connection with the county and state systems. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. None. Condition at end of fiscal year.

APPOMATTOX RIVER, VA. Location. This river rises in Appomattox County, Va., flows northeasterly 137 miles, and empties into the James River at 454 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Hopewell, Va. The portion under improvement extends from its mouth to Petersburg, Va., a distance of 111/ miles, which is the length of the tidal and navigable reach. (See U. S. Coast and Geodetic Survey Chart No. 531.) Previous projects. None. A survey of the river was made prior to the adoption of the existing project. For further details, see page 469, Annual Report for 1938. Existing project. This provides for a channel 80 feet wide and 12 feet deep from the mouth of the river to a point 400 feet above Lieutenant Run; thence 80 feet wide and of such depth, not ex- ceeding 12 feet, as can be obtained without rock excavation to the head of navigation at Petersburg; including a basin at the mouth of Poes Run 200 feet long, 150 feet wide, and 20 feet deep; and a turning basin at the mouth of Lieutenant Run 500 feet long, 140 to 160 feet wide, and 12 feet deep in the upper 300 feet, the removal of rock to a depth of 18 feet in the north half of the lower 200 feet, and removal of soft material to rock in the south half of the lower 200 feet of this basin. All depths are referred to mean low water. The project also provides for a dam at Petersburg and the excavation for a width of from 200 to 300 feet of a diversion channel connecting the river above the dam with the river at a point 21/ miles below; for about 1.7 miles of levees on the low grounds between the navigable and the diversion channels; for a highway bridge and a railway bridge across the diversion chan- nel; and for other work incidental to the diversion channel. Under ordinary conditions the mean tidal range is 2.9 feet and the extrerpes 2.4 and 3.3 feet. There are no records available of the heights of stage due to ordinary floods. These are estimated at 6 to 8 feet above mean low water at Petersburg, where the the extremes are from 15.6 feet to 17.1 feet. The estimated cost of new work, revised in 1951, is $1,176,400, which includes the completion of the diversion channel at a cost of $295,000. The estimated cost of maintenance (1950) of the navigable channel is $15,000 annually.

At the elevation of the top of gates, Gathright Reservoir will extend upstream about 15 miles. (See Falling Spring and Mountain Grove, Va.-W. Va., quadrangles of the United States Geological Survey.) Existing project. This project provides for the construction of the Gathright Dam and the Falling Spring Reregulating Dam on the Jackson River. The Gathright Dam will be a rock-fill dam with impervious earth core having a maximum height of 248 feet above stream bed and a crest length of 800 feet with a gated side-chan- nel concrete spillway. At the elevation of the top of gates, the dam will provide a total storage capacity of 417,000 acre-feet, of which 110,000 acre-feet will be flood storage; 264,000 acre-feet, power FLOOD CONTROL-NORFOLK, VA., DISTRICT 489 draw-down; and 43,000 acre-feet, dead storage. The power plant will have an installed capacity of 34,000 kilowatts. The variable flow from this power installation will be reregulated by the Fall- ing Spring Dam, which will be a low, gravity-type, concrete structure, with an earth embankment at the right abutment. The Falling Spring Dam will have a maximum height of 64 feet and a crest length of 850 feet, of which 640 feet will be concrete and 210 feet will be earth fill. The storage at spillway crest elevation will be 4,700 acre-feet, of which 4,000 acre-feet will be available for stream-flow regulation. The estimate of Federal cost for the project, including both dams and reservoirs, revised in 1951, is $20,700,000 for construc- tion and $1,700,000 for lands and damages, including highway, railroad, and utility relocation, a total of $22,400,000 for new work. The project, as set forth in House Document 207, Eightieth Congress, first session, was authorized by the Flood Control Act approved July 24, 1946.

Existing project. This provides for a waterway 12 feet deep at mean low water, with bottom widths varying from 90 feet in land cuts to 300 feet in open waters; for the construction, opera- tion, and maintenance of suitable bridges; for a tidal lock in the land cut near the Cape Fear River; for a channel 12 feet deep at mean low water and 90 feet wide on the bottom in New River between the Inland Waterway and the Atlantic Coast Line Rail- road bridge at Jacksonville, N. C., 21 miles, and a basin at Jack- sonville of the same depth and varying in width; for a side chan- nel 12 feet deep and 90 feet wide to a turning basin of the same depth, 200 feet wide and 350 feet long, opposite the principal wharves at Swansboro; for an entrance channel 6 feet deep and 90 feet wide at New River Inlet, with connecting channel of same dimensions to the Intracoastal Waterway near the mouth of New River; for six mooring basins at various locations along the waterway; for a channel 14 feet deep and 400 feet wide across the ocean bar at Masonboro Inlet, thence 12 feet deep and 90 feet wide to the channel of the Inland Waterway at Wrightsville by way of Banks and Motte Channels; a turning basin 15 feet deep having a maximum width of 300 feet and length of 700 feet on the east side of Banks Channel near Masonboro Inlet, with three 15-pile dolphins therein; for a jetty on each side of Masonboro Inlet extending to the 14-foot depth in the ocean; for a yacht basin 230 feet wide, 450 feet long, and 12 feet deep near the town of Southport, connected with the waterway by a suitable channel of the same depth; and for salt-water-intrusion preventive measures in the vicinity of Fairfield, N. C., as follows: Construction of a pumping plant and a dam, with control gates and appurtenant works on Fairfield Canal near the Inland Water- way; restoration and enlargement where necessary of Boundary Canal from the vicinity of Swindell Canal to the vicinity of Baum Canal, together with appurtenant works necessary to cut off inflow from other areas; and construction of dams with 30-inch automatic floodgates across Swindell, Florida, Burris, and Baum Canals near Mattamuskeet Lake. That portion of the waterway north of the mouth of Neuse River is nontidal; variation in the water surface, due to winds, seldom exceeds 2 feet above or below mean stage. In the section between Beaufort and Cape Fear River the tidal range varies from 31/2 feet at the inlets to 1 foot at points between. The tidal range for New River varies from 31/ feet at New River Inlet RIVERS AND HARBORS--WILMINGTON, N. C., DISTRICT 493 to 1 foot at the head of the marshes, and nothing at Tar Land- ing, 31 miles above. The mean range of tide in the section from Cape Fear River, N. C., to Little River, S. C., varies between 4.7 feet in Cape Fear River, 4 feet at intermediate inlets, and 2 feet at points midway between inlets. The estimate of cost for new work, revised in 1951, exclusive of amounts expended on previous projects, is $10,241,900, ex- clusive of jetties at Masonboro Inlet, and $11,831,900.55 including the jetties.

MOREHEAD CITY HARBOR, N. C. Location. This harbor is on the northern shore of Bogue Sound, adjacent to Beaufort Harbor and Inlet. New Bern, N. C., the nearest city of importance, is about 43 miles by inland waterway to the northwest. (See U. S. Coast and Geodetic Sur- vey Chart No. 420.) Previous project. The channel across the ocean bar was for- merly improved under the title of Beaufort Inlet, N. C. The project was adopted by the River and Harbor Act of March 3, 1905 (H. Doc. 563, 58th Cong., 2d sess.). For further details, see page 470 of Annual Report for 1935. Existing project. This provides for a channel 30 feet deep and 400 feet wide across the ocean bar at Beaufort Inlet, thence same depth and 300 feet wide to the marine terminals at Morehead City, enlarged to 600 feet to form a turning basin at that point, and for construction of jetties at the inlet; for a channel 12 feet deep and 100 feet wide from the 30-foot channel to Sixth Street, Morehead City, thence same depth and 200 to 400 feet wide to Tenth Street, thence 6 feet deep and 75 feet wide to deep water in Bogue Sound. The average rise of the tide is about 21/2 feet at Morehead City and 31/2 feet at the inlet. Observations made in 1907 showed an extreme range of 4.8 feet. The estimate of cost of new work, revised in 1950, is $2,221,- 100. The latest (1951) approved estimate for annual cost of maintenance is $200,000.

Local cooperation. The project provides that local interests furnish, free of cost to the United States, spoil-disposal areas as required for new work and for future maintenance and all other lands needed for the improvement, and to the further condi- tion that local interests give assurances satisfactory to the Sec- retary of War that an adequate terminal open to the public on uniform terms will be available by the time the channel is com- pleted. Terminals have been completed and spoil-disposal areas for new work furnished. Lands needed in connection with the construction of jetties have not been furnished. Terminal facilities. There are 37 wharves along the main water front of the town, with a total frontage of about 1,182 feet. The marine terminals provide 1,350 feet of berthing space with a depth alongside of 27 feet at mean low water, and facili- ties for transfer of cargoes between rail and water carriers. The existing facilities are considered adequate for existing and prospective commerce. Operations and results during fiscal year. The work consisted of maintenance dredging with Government plant and hired labor and miscellaneous surveys. Between November 22, 1950, and January 31, 1951, the U. S. hopper dredge Lyman removed 616,760 cubic yards of material from the ocean-bar channel and the outer end of the inside 30- foot channel at a cost of $121,610.87. Between August 23 and 24, 1950, the U. S. dredge Josenhans removed 2,488 cubic yards of material from the 6-foot channel to Bogue Sound at a cost of $942.02. Miscellaneous surveys cost $8,643.29. The total costs were $131,196.18 for maintenance. The ex- penditures were $132,889.46. Condition at end of fiscal year. The existing project was 40 percent completed. The part of the existing project providing for a 12-foot channel to Morehead City, thence a 6-foot channel westward to Bogue Sound was commenced in February 1931 and completed in March 1931; the part providing for the 30-foot channel to the terminals was commenced in November 1935 and completed in August 1936. No work has been done on the jetties proposed for Beaufort Inlet. At the close of the fiscal year a depth of 29.6 feet was available in the ocean-bar channel; 27.8 feet in the 30-foot channel (inside) to the terminals at Morehead RIVERS AND HARBORS-WILMINGTON, N. C., DISTRICT 505 City; 12 feet from deep water in the outer harbor to the foot of 'Tenth Street, Morehead City, and thence 6 feet westward to Bogue Sound.

The terminal facilities at the port of Georgetown served by this improvement consist of four wharves of ordinary timber construction, one of creosoted-timber con- struction, suitable for oceangoing vessels, and a number of smaller wharves and landing places. These are considered adequate for the present commerce of the port. Operations and results during fiscal year. New work: The U. S. pipeline dredge Henry Bacon and hired labor during October 1950 suspended dredging operations to 27-foot depth in a 5,800- foot reach of the Entrance Channel, having removed 417,769 cubic yards of material at a cost of $162,169.43. The U. S. hopper dredge Lyman and hired labor suspended dredging operations in the Entrance Channel during the latter part of April 1951, having removed 637,885 cubic yards of material at a cost of $161,225.97. The derrick boat Little Boss, under contract, removed logs, stumps, and debris from a depth of about 25 feet in the Entrance Channel, at a cost of $37,941.57 to the end of the fiscal year. The total cost during the year was $361,336.97 for new work. The expenditures were $444,709.70. Maintenance: Dredging by contract to restore project di- mensions in the Sampit River, upper Winyah Bay, and Eastern Channel portions of the project was commenced by the pipeline dredges Pullen and Hampton Roads, during February 1951, and will be completed during the early part of the fiscal year 1952. To the end of the fiscal year these dredges removed a total of 2,523,483 cubic yards of material at a cost of $364,916.34. In addition to the above, Government cost was incurred in the amount of $1,253.28 on contract work completed prior to June 30, 1950. The cost of surveys and supervision was $4,297.37. The total cost during the year was $370,466.99. The expenditures were $334,359.83. Condition at end of fiscal year. A channel 18 feet deep and 400 feet wide from the entrance of Winyah Bay to the head of the project was completed in 1937 with the completion of Eastern Channel. The jetties were completed in 1903-4. The crest eleva- tions range from 8 to -4 feet and are as much as 12 feet below their original heights. Dikes of various forms have been built to protect the South Island beach and the shore end of the south jetty. An earth dike 4,100 feet long has been constructed east 528 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 of the Eastern Channel, largely from original channel exca- vation, to assist in maintaining the channel. The Sampit River entrance is protected on the eastern side by a timber-and-brush training wall 2,000 feet long. The project is 99 percent com- pleted; the work remaining consists of minor dredging in the Entrance Channel. Surveys in June 1951 showed a controlling depth of 22.5 feet for 100-foot width from the ocean to the Gorge Channel, thence 23.5 feet through the lower 3.5 miles of Eastern Channel, thence 23 feet to the head of the project, via the Sampit River cut-off, including the side channel and turning basins. Center-line surveys made in June 1951 showed a controlling depth of 12 feet in the bypassed portion of Sampit River, 13 feet in the seldom-used Western Channel from its junction with lower Eastern Channel to the mouth of the Estherville-Minim Creek Canal, and 14 feet to its junction with upper Eastern Channel (link of the Atlantic Intracoastal Waterway). The costs of the existing project to the end of the fiscal year have been $4,600,890.93 for new work and $2,115,075.80 for maintenance, a total of $6,715,966.73. The expenditures have been $6,622.509.67. Proposed operations.

For further details see page 1808, Annual Report for 1915; page 579, Annual Report for 1926; page 562, Annual Report for 1938. Existing project. This provides for commercial purposes a channel 35 feet deep, 1,;000 feet wide from the sea to the inner end of the jetties, thence 600 feet wide to Town Creek, thence 500 feet wide through Town Creek, thence 600 feet wide to the navy yard, and thence 400 feet wide to Goose Creek, with a turn- ing basin 700 feet wide at the port terminals, together with a channel 30 feet deep, 600 feet wide in Cooper River around the east and north sides of Drum Island; also an anchorage area 30 feet deep in the water area between Castle Pinckney and Fort Moultrie; also a channel in Shem Creek 10 feet deep and 110 feet wide from a flared entrance from Hog Island channel to and including a turning basin 130 feet wide and 400 feet long with the upper end 250 feet upstream of the Mount Pleasant public wharf. The estimate of cost for new work, revised in 1951, is $4,304,- 500, exclusive of amounts expended under previous projects. The latest (1951) approved estimate of annual cost of maintenance is $615,000. The existing project includes the maintenance of two entrance jetties completed in 1895 under previous projects. These jetties are of stone on log-mattress foundation, the north jetty 15,443 feet long and the south jetty 19,104 feet long; the distance be- tween their axes at the outer end is 2,900 feet. The height as 530 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 originally built, except the submerged inner portions and the gap left in the south jetty, was 12 feet above mean low water for the greater part of their length. The project also provides for a 40-foot channel 1,000 feet wide from the sea to the inner ends of the jetties, described above, thence 600 feet wide to the south pier at the navy yard, and thence 1,000 feet wide to the commandant's wharf, at an estimated first cost of $3,603,000 and $250,000 annually for maintenance, both figures being additional to the estimates for the commercial project given above, and that it be considered as a national de- fense rather than a commercial measure and be prosecuted only as found necessary in the interest of national defense. The mean tidal range is 5.2 feet, though this is increased to 7 or 8 feet under the influence of northeast winds or prolonged storms.

The facilities are considered ade- quate for existing commerce. For further details, see Port Series No. 13, revised 1950, Corps of Engineers. Operations and results during fiscal year. The U. S. hopper dredge Gerig and hired labor completed restoring project di- mensions in the Entrance and South Channels on August 31, 1950, removing 2,055,883 cubic yards of material at a cost of $155,379.60. The pipeline dredge Pullen, under contract, com- pleted restoring project dimensions in 'Town Creek and Cooper River Channels on August 16, 1950, removing 273,806 cubic yards at a cost of $58,541.19, and on June 18, 1951, commenced maintenance dredging operations in Cooper River north of Drum Island, and to the end of the fiscal year removed 82,580 cubic yards of material at a cost of $21,285.20. Tests of improvement plans in the model of Charleston Harbor constructed at the United States Waterways Experiment Station, Vicksburg, Miss., were continued and companion prototype studies in Charleston Harbor were made by district office personnel; costs in connection with the model study were $127,003.73. The cost of surveys and supervision was $8,261.96. The total cost during the year was $370,471.68 for maintenance. The ex- penditures were $451,452.46. Condition at end of fiscal year. The jetties protecting the entrance channel accross the bar were completed in 1895. These jetties are described in "existing projects." The existing project was completed during May 1949, except for the anchorage area 30 feet deep in the water area between Castle Pinckney and Fort Moultrie. Surveys during the latter part of the fiscal year in the En- trance, South, and Cooper River Channels showed a controlling depth of 34 feet for 300-foot width from the 35-foot contour in the ocean to the head of the project, except in lower Cooper River where the controlling depth is 31 feet for 300-foot width, and at shoals in Cooper River, north of Drum Island, where the controlling depth is 27 feet for 200-foot width, and in Town Creek where the controlling depth is 26 feet for 300-foot width. A sur- vey in Shem Creek during November 1949 showed that project dimensions obtained.

JOHNS RIVER, FLA. (SAVANNAH DISTRICT) Location. This section of the waterway connects Port Royal Sound, S. C., with Fernandina, Fla. (See U. S. Coast and Geodetic Survey Charts Nos. 838-841, inclusive.) For Cumberland Sound to St. 'Johns River section see page 576. Previous projects-between Savannah, Ga., and Fernandina, Fla. Previous improvements in this section were authorized by River and Harbor Acts of August 2, 1882, August 11, 1888, July 13, 1892, and March 3, 1905. For further details see pages 1814, 1821-1823, Annual Report for 1915, and page 585, Annual Report for 1938. Existing project. This provides for a waterway 12 feet deep at mean low water and not less than 90 feet wide between Port 543 544 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Royal Sound, S. C., and Savannah, Ga.; for a waterway 12 feet deep at mean low water, with widths of 90 feet in land cuts and narrow streams and 150 feet in open waters, between Savannah, Ga., and Fernandina, Fla., to follow in general the alinement of the existing waterway, except for such cut-offs or other changes in the route as may be found desirable and justified by the re- sultant benefits to navigation; and for a suitable anchorage basin at Thunderbolt, Ga. The total distance from Port Royal Sound, S. C., to Fernandina, Fla., is 165 miles. The project also provides for the following: (1) removing logs and snags from Generals Cut, Ga.; (2) an alternative and more protected route 7 feet deep at mean low water from Doboy Sound to Brunswick Harbor, via Darien River, Three Mile Cut, Altamaha River, One Mile Cut, Buttermilk Sound, Mackay River, Back River, Clubbs Creek, and Plantation Creek; (3) a protected channel 7 feet deep at mean low water and 75 feet wide around St. Andrews Sound, extending from the main route of the waterway in Jekyll Creek through Jekyll Sound, Little Satilla River, Umbrella Cut, Umbrella Creek and its south branch, through Dover Cut to Dover Creek, thence up Dover Creek and through a narrow neck of land to Satilla River, thence through a land cut south of Todd Creek and through Floyd Creek to the main route of the waterway in Cumberland River; (4) a channel 5 feet deep at mean low water and 50 feet wide to con- nect Baileys Cut to Satilla River and Dover Creek, Ga.; (5) a loop 8 feet deep at mean low water to reach the wharves at the southern end of Cumberland Sound; (6) an alternative route 9 feet deep and 150 feet wide in that part of Frederica River, Ga., not now traversed by the main route, at no additional cost to the United States. In general, the work is to be accomplished by dredging, supplemented by training walls as necessary. The mean tidal range between Port Royal, S. C., and Fernan- dina, Fla., is from 6 to 8 feet, with fluctuations from 11/2to 21/2 feet, due to winds and lunar phases. The project has been completed at a cost of $763,599.20 for new work, exclusive of amounts expended under previous proj- ects. The latest (1951) approved estimate for annual cost of maintenance is $300,000.

These facilities are considered ample for existing commerce. Operations and results during fiscal year. Maintenance: Be- tween July 24 and October 9, 1950, the contract dredge Hampton Roads removed 1,036,560 cubic yards of material from the main route of the waterway (Wilmington River, mile 578.5 to mile 583.4) at a cost of $106,064.18. Between May 7 and June 30, 1951 the contract dredge Savan- nah removed 475,510 cubic yards of material from the main route of the waterway (Jekyll Creek, mile 681.5 to mile 683.3) at a cost of $55,227.62. Plans and specifications for dredging contract in Jekyll Creek cost $1,050.55. Repairs to speed and directional markers cost $6,707.70. Mis- cellaneous surveys cost $5,780.44. The total cost for maintenance was $174,830.49. The expendi- ture was $140,852.08. Condition at end of fiscal year. The main 12-foot channel of the existing project was completed in 1941. The 7-foot protected 546 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 route around St. Andrew Sound was completed in 1939. The training walls and closure dams were completed in 1912, and are in satisfactory condition. All other improvements were completed in 1932. Since March 1943, the previous route of the Intracoastal Water- way, through the westerly end of South Channel and the northerly end of Wilmington River, has been superseded by the route through the Elba-McQueens Island Cut and the northwesterly end of St. Augustine Creek. The former route will be maintained to a depth of 7 feet for traffic moving from Savannah to points south of Savannah Harbor and for north-bound traffic from southern points below Savannah Harbor to Savannah, Ga. In June 1951, the main route had a controlling depth of 12 feet or more except as follows: Walls Cut (mile 572.2), 11 feet; Fields Cut (miles 573.5 to 573.7), 10 feet; Elba-McQueens Island Cut (mile 576.5), 9 feet; Wilmington River (miles 578.5 to 583.4), 9 feet; Hell Gate (miles 601.6 to 602.3), 10 feet; Florida Passage (mile 607.6), 10 feet; Front River (mile 638.6), 11 feet; Doboy Sound (mile 694.4), 11 feet;'-Rockdedundy River (mile 652.9), 9 feet; Little Mud River (mile 655), 11 feet; Buttermilk Sound (mile 663), 9 feet; Mackay River (mile 668.8), 11 feet; St. Simon Sound (mile 677.4), 11 feet; and Jekyll Creek (miles 683 to 685.4), 9 feet. The costs under the existing project to June 30, 1951, were $763,599.20 for new work and $3,837,340.11 for maintenance, a total of $4,600,939.31. The expenditures were $4,566,636.87.

Adopted by specific acts of Congress May 18, 1826; March 3, 1855; August 7, 1856; and by River and Har- bor Acts of March 3, 1873; June 23, 1874; September 19, 1890; June 3, 1896; and June 13, 1902. For further details, see page 1810, Annual Report for 1915, and page 578, Annual Report for 1938. Existing project. This consists of eleminating the regulating dam across South Channel, relocating the inland waterway in the vicinity, further extending training walls, revetments, and jetties, and providing for- (a) Channels 36 feet deep and 500 feet wide across the ocean bar between stations 245 and 194, 9.7 miles; thence 34 feet deep and generally 400 feet wide, increased to 550 feet opposite the Atlantic Coast Line terminals, between stations 194 and 103, with a turning basin 34 feet deep at the Mexican Petroleum Corp. refinery, 17.2 miles; thence 30 feet deep and 300 feet wide to the foot of Kings Island, 0.6 mile; thence 30 feet deep and 200 feet wide to the vicinity of the Atlantic Creosoting Co, terminal, with a turning basin 30 feet deep, 2.1 miles; thence 30 feet deep and 200 feet wide to a point 1,500 feet below the Atlantic coastal highway bridge, with a turning basin 30 feet deep at the upper end, 1.45 miles; a total length of 31.05 miles; and with such modifications thereof as the Secretary of the Army and the Chief of Engineers may consider desirable. (b) Enlargement of contracted portions of the channel and such enlargements of the channel as may be necessary to smooth out abrupt changes and for otherwise improving the hydraulic conditions with a view to reducing shoaling. (c) The maintenance of the channels, anchorage basins, en- largements at Drakies Cut, Kings Island, West Broad and Bar- nard Streets, mooring dolphins near Fort Oglethorpe, and the existing training walls and jetties. 'The plane of reference is mean low water, which varies for different parts of the harbor. The mean range of tide is 7.6 feet 548 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 at the upper end of the harbor and 7.1 feet at the lower end. Ex- treme ranges are about 10.5 feet and 11 feet, respectively. Tides below mean low water occur six or seven times a month and minus 2-foot tides occur from six to eight times a year. The improvement has increased the mean tidal range by about 2.8 feet at the upper end. The estimate of cost for new work, revised in 1951, is $9,- 097,700, exclusive of amounts expended on previous projects. The latest (1951) approved estimate for annual cost of maintenance is $1,500,000.

Local cooperation. The River and Harbor Acts approved November 7, 1945, and July 24, 1946, impose the conditions that local interests shall (a) provide, free of cost to the United States, all lands and rights-of-way required for the initial construction and subsequent maintenance when and as required; (b) hold and RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 549 save the United States free from damages due to the construction works. To date, local interests have obtained temporary easements for 1-year periods for spoil areas over about one-half the area that requires maintenance dredging. All easements furnished by local interests have been of short duration and are becoming increasingly difficult to obtain, due to the marsh land being built up by dredge spoil, making the properties suitable for industrial delevopment. Short-term or temporary easements are also un- satisfactory in that many of the areas must be diked at con- siderable expense, and there is the danger that the expenditure may be lost if the easements are not of sufficient duration to provide for the full utilization of the diked areas. The city of Savannah has been notified that the failure to provide easements as required will necessitate the cessation of maintenance dredg- ing in the Savannah Harbor. The city has appropriated $10,000 to its agents, Savannah District Authority, to finance the obtain- ing of necessary easements. No long-term easements have been obtained to the date of this report, and short-term easements often have been furnished only a few days before they are required. Terminal facilities. There are 51 piers and wharves to serve water-borne commerce of the port. These facilities, with the use of dolphins, have a combined berthing space of 33,800 feet, with depths of water alongside ranging from zero to 32 feet at mean low water. Six of these terminals are opposite the city on Hutch- inson Island; the remaining 45 are on the south side of the river between 3 miles below and 6.8 miles above the center of the city. Thirteen piers and wharves are operated by railroads, five by oil companies, two by coal companies, one by a cotton warehouse company, five by ship repair companies, one by a local steamship company, seven by various private industries, and one by the Georgia Ports Authority. The latter wharf, with existing facili- ties, will be developed for State port terminals. The site of a former shipyard has been acquired by the city of Savannah for future development of industrial sites. There is a large municipal wharf at the center of the city. All have railway and highway connections except the six on Hutchinson Island, which have rail connections only. The facilities are considered adequate for exist- ing commerce. For further details see Port Series No. 14, Corps of Engineers (revised 1946). Operations and results during fiscal year. New work: The U. S. hopper dredge Gerig operated on the bar channels during the period September 13, 1950 to April 15, 1951, removing 2,864,502, cubic yards of material at a cost of $512,121.24.

The existing project was about 93 percent completed. The 30-foot channel and extension of the harbor above the Seabord Air Line Railroad bridge was com- pleted February 5, 1948. The 34-foot channel was completed May 20, 1949, except for a section immediately above and below the Seaboard Air Line Railroad bridge which cannot be accomplished until that bridge has been reconstructed. The 36-foot bar chan- nel was completed April 15, 1951. The previous 30-foot project from the sea to old quarantine station was completed in 1930, and the rest of the 30-foot channel in 1937. That part of the previous 26-foot channel from the Seaboard Air Line Railroad bridge to the foot of Kings Island was completed in 1931; the rest, from the foot of Kings Island to the Atlantic Creosoting wharf, including the turning basin opposite the Savannah Sugar RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 551 Refinery's wharf, in 1937. Cross-tides channel was closed with a hydraulic fill in 1937. The anchorage basin and mooring dolphins near Fort Oglethorpe were completed in 1926; of the 10 dolphins originally constructed, all have been destroyed. The channel en- largements at Drakies Cut, Kings Island, and at West Broad and Barnard Streets, were completed in 1931, 1929, and 1924, respec- tively. Whitehall channel training wall was completed in 1929 and was replaced by three spur dikes in 1937; these spur dikes are in good condition. Fig Island training wall was raised and extended in 1940 and is in good condition. Long Island training wall hydraulic fill was completed in 1931 and other training walls and jetties prior to 1929, and are in fair condition. In June 1951, least depths in mid channel for half project width at mean low water were 36 feet from the sea to Blinker 24 (in the vicinity of Fort Pulaski) ; thence 27 feet to and through the Seaboard Air Line Railroad bridge; thence 28 feet to the wharf of the Southern Paperboard Corp.; thence varying from 28 feet to 14 feet at the extreme upper limit of the harbor. The turning basins had the following controlling depths: Kings Island Turning Basin, 28 feet; Whitehall Turning Basin, 29 feet; Port Wentworth Turning Basin, 25 feet. The work remaining to be done to complete the project is as follows: Re-align and dredge the 34-foot channel from a point (station 109) below the Seaboard Air Line Railroad Company's bridge to a point (station 103) above the bridge, opposite the Mexican Petroleum Corpora- tion Refinery; construction of bank protection and extension of permeable dikes in the upper reaches of the harbor. The costs under the existing project to June 30, 1951, have been $8,449,553.97 for new work and $19,751,357.25 for main- tenance, a total of $28,200,911.22. The expenditure was $28,- 193,890.83.

SAVANNAH RIVER BELOW AUGUSTA, GA. Location. This river is formed by the confluence of the Tuga- loo and Seneca Rivers on the northwestern part of the South Carolina-Georgia boundary line. It flows southeast 314 miles, forming the boundary line, and empties into the Atlantic Ocean 16.6 miles below Savannah, Ga. (See U. S. Geological Survey maps of South Carolina and Georgia.) RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 553 Previous project. Adopted by the River and Harbor Act of March 3, 1881. A subdivision between new work and maintenance is not possible. For further details see page 1813, Annual Report for 1915 and page 581, Annual Report for 1938. Existing project. Provides for a channel 9 feet deep and 90 feet wide (at ordinary summer flow, which corresponds to a dis- charge of 5,300 second-feet at Augusta, Ga., with the Clark Hill power plant in operation), from the upper end of Savannah Harbor to the head of navigation at Augusta, 3 miles above Fifth Street Bridge, about 199 miles. The improvement is to be obtained by construction of one lock and dam at New Savannah Bluff, use of contraction works, closure of cutoffs, bank protection, dredging, removal of snags, overhanging trees and wrecks, and open-river regulation. The mean tidal variation at the mouth of the river is 7.1 feet. The freshet variation above the normal pool level (elevation 114.5 mean sea level) of the New Savannah Bluff lock and dam at the head of the improvement is ordinarily about 13 feet with an extreme of 34 feet.

ARMY, 1951 Local cooperation. The project provides that local interests furnish, without cost to the United States, all necessary rights- of-way and spoil-disposal areas for the new work and subsequent maintenance, when and as required; hold and save the United States free from any damage resulting from construction and maintenance of the improvement; and provide and maintain adequate terminal and transfer facilities, including a suitable public terminal at Augusta, Ga., open to all on equal terms. Terminal facilities. The only water terminals served by this improvement are at Augusta and at or near Savannah. The city of Augusta owns and operates, on equal terms to all, a wharf and warehouse; a short distance below this terminal the Pure Oil Co. has a terminal (storage capacity of 27,500 barrels) for berthing and discharging oil barges; and just outside the eastern city limits is the Merry Bros. Brick & Tile Co.'s terminal. This com- pany also has terminal facilities at Savannah. At Savannah there is one municipal wharf, suitable for berths for river steamers, open to the public on equal terms. In addition, there are ex- tensive facilities at Savannah, privately owned, for oceangoing and smaller vessels. Along the river there are numerous natural landings without wharves or railway connections. The terminal facilities are considered ample for existing commerce. Operations and results during fiscal year. Maintenance: The U. S. snagboat Macon and hired labor did maintenance snagging from July to October 1950 and May through June 1951, re- moving 1,682 obstructions between Savannah, Ga., and Augusta, Ga., at a cost of $36,201.26. Surveys and engineering studies cost $4,315.13. The minimum daily flow of the river at the New Savannah Bluff Lock and Dam during the fiscal year 1951 was 2,550 cubic feet per second on August 9, 1950. Minimum weekly flow was 3,250 cubic feet per second. The minimum daily and weekly flows of record prior to 1951 were 1,105 and 1,220 cubic feet per second, respectively. Power plants with storage on the river are the Stevens Creek plant, 9 miles above Augusta, and the six plants of the Georgia Power Company on the headwaters. No regulation of the flow is required at headwater plants, but the Stevens Creek plant is required to pass the natural flow of the river when this is at or below 6,550 cubic feet per second at the New Savannah Bluff Lock and Dam. The Stevens Creek plant has so operated during the past year, but the effect of the headwater plants on the natural flow of the river has not been determined. Maintenance (operating and care) : The lock and dam at New Savannah Bluff was operated, and ordinary repairs, improve- ments, and reconstruction to the structure and appurtenant works were made at a cost of $36,605.22. The total cost of work from regular funds was $77,121.61- $40,516.39 for maintenance and $36,605.22 for operating and care. The expenditure was $71,920.73. Condition at end of fiscal year. The existing project, was about 43 percent completed in 1939.The lock and dam at New RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 555 Savannah Bluff was completed in 1937. The lock and dam is in good repair. In general, the open-channel works are in fair condition; a few of the structures are in need of repairs, how- ever, this work will be accomplished by the present modifica- tion to the existing project. The controlling depth at ordinary summer water was 4 feet or greater for about 85 percent of the fiscal year. This depth corresponds to a height of 4.2 feet on the Butler Creek gage and to a discharge of 4,000 second-feet at Augusta. The work remaining to be done to complete the project is as follows: Deepen the channel to 9 feet and widen to 90 feet between the upper end of Savannah Harbor and the present head of navigation at Augusta, Ga.

ALTAMAHA, OCONEE, AND OCMULGEE RIVERS, GA. Location. These rivers are entirely within the State of Georgia. (See U. S. Geological Survey map of Georgia.) For full description of these rivers, see page 636, Annual Report for 1932. Previous projects. Prior projects for the Altamaha River had been adopted, and expenditures made under them, by. River and Harbor Acts of March 3, 1881, and September 19, 1890; for the Oconee River by River and Harbor Acts of June 18, 1878, September 19, 1890, and March 3, 1905; for the Ocmulgee River, by River and Harbor Acts of August 14, 1876, and September 19, 1890. For further details, see page 1815, Annual Report for 1915, and page 589, Annual Report for 1938. Existing project. This contemplates an appropriation of $40,- 000 annually for the Altamaha, Oconee, and Ocmulgee Rivers, to be applied, following in general the methods carried on under the previous projects, to maintenance of 3-foot depth during ordinary summer low water and to the gradual increase of channel depth, so far as practicable without sacrificing the main- tenance work. These methods are removing rock shoals, snags, overhanging trees, and other obstructions; closing incipient cut- offs; revetting caving banks; and use of spur dikes and training walls. The width of channel was not specified, but it should vary from 60 to 100 feet, according to locality. The present proj- ect provides also for removing obstructions such as overhanging trees and submerged stumps, snags, and logs from Rifle Cut. This project covers the entire Altamaha River (including a chan- nel between the river and Darien, Ga.), a length of 137 miles, the lower 145 miles of the Oconee River, and the lower 205 miles on the Ocmulgee River. The Altamaha River has a mean tidal range of 6.4 feet at its mouth which gradually decreases to mile 33 above, where there is no perceptible tidal effect. At Doctor- town, mile 59, ordinary floods attain a height of about 10 feet above low water, and extreme floods a height of about 15 feet above low water. RIVERS AND HARBORS-SAVANNAH, GA., DISTRICT 557 On the Oconee River at Dublin the ordinary fluctuations attain a height of 22 feet, and the extreme fluctuations a height of 32 feet, above low water. On the Ocmulgee River at Macon the ordinary fluctuations attain a height of 15 feet, and the extreme fluctuations a height of 25 feet, above low water. There is no approved estimated cost for improvement or for maintenance. The existing project was adopted by the River and Harbor Acts of July 25, 1912 (H. Doc. 443, 62d Cong., 2d sess.), and March 2, 1945 (H. Doc. 610, 77th Cong., 2d sess.). The latest published maps of these river are in the following documents: Altamaha River, House Executive Document 283, Fifty-first Congress, sec- ond session; Oconee River, House Executive Document 211, Fifty- first Congress, first session; Ocmulgee River, House Executive Document 215, Fifty-first Congress, first session; and Lower Altamaha River and Darien Harbor, Ga., House Document 610, Seventy-seventh Congress, second session. Local cooperation. Fully complied with. Terminal facilities. Along these rivers there are numerous natural shore landings. These are considered ample for existing commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project is such that the percentage of completion cannot be stated. Channel depths have been increased by excavating rock shoals and sand bars, by constructing contraction and bank-protection works, and by closing cut-offs. Navigation has been rendered safer by removing obstructions. Many of the closing dams and contrac- tion and bank-protection works need repairs. During the year: The Altamaha River had a controlling depth of 3 feet or greater 55 percent of the time. The Oconee from the Forks to Dublin, Ga., had a controlling depth of 3 feet or greater 65 percent of the time. The Ocmulgee River from the Forks to Abbeville, Ga., had a controlling depth of 2.5 feet or greater 60 percent of the time. Low water usually occurs between August and November. Con- trolling depths were then one-half to 1 foot less than those given above. To June 30, 1951, the costs under the existing project were $60,847.16 for new work and $938,135.15 for maintenance, a total of $998,982.31. The expenditures were $998,982.31. Proposed operations.

The site of the Hartwell Dam is on the Savannah River 306.9 miles above its mouth and 89 miles upstream from Augusta, Ga. At full-power-pool elevation, the reservoir will extend 7.1 miles up the Savannah River to the confluence of the Tugaloo and Seneca, 41 miles up the Tugaloo to within about 2 miles of the existing Yonah Dam, 27 miles up the Seneca to the mouth of upstream Little River, S. C., thence 2 miles up Little River to the Newry site and 7 miles up the Keowee to the Old Pickens site, and 8 .miles up Deep Creek. (See U. S. Geological Survey maps of Georgia and South Carolina.) Existing project. The Flood Control Act approved May 17, 1950, authorized $50,000,000 to be appropriated for constructing the Hartwell Reservoir in the general plan for the comprehensive development of the Savannah River basin approved in the Flood Control Act of December 22, 1944, in addition to the authoriza- tion for project construction in the Act of December 22, 1944, recommended in House Document No. 657, Seventy-eighth Con- gress, second session. This project provides for a gravity-type concrete dam 2,415 feet long with earth embankments at either end, 6,050 feet long on the Georgia side and 3,935 feet long on the South Carolina side. The total length of the dam will be about 12,400 feet, with a roadway over the top 24 feet wide. The main dam will consist of two nonoverflow concrete sections on the right and left bank 887 feet and 940 feet long, respectively, a gravity-type concrete spillway 588 feet long equipped with 12 Tainter gates 26 by 40 feet, in the channel, and a powerhouse on the South Carolina side of the river. The maximum height of the concrete section will be 210 feet above river bottom and the earth-fill embankments will vary in height to a maximum of about 55 feet. At full-power-pool elevation 660 the reservoir FLOOD CONTROL-SAVANNAH, GA., DISTRICT 569 will provide a total storage of 3,528,000 acre-feet of which 1,- 567,000 acre-feet will be usable with the proposed 12.8-foot drawdown. The initial and ultimate power installation will be 177,400 kilowatts. The estimated cost, revised in 1951, is $62,509,000 for con- struction, $4,138,000 for lands, and $10,853,000 for relocations and rights-of-way, a total of $77,500,000.

CLARK HILL RESERVOIR, SAVANNAH RIVER BASIN, GA. AND S. C. Location. The work covered by this project is a dam and reservoir on the Savannah River and its tributaries in Georgia and South Carolina. (See U. S. Geological Survey maps of Georgia and South Carolina.) Existing project. The Flood Control Act approved December 22, 1944, approved the general plan for the comprehensive devel- opment of the Savannah River basin for flood control and other purposes as recommended in House Document No. 657, Seventy- eighth Congress, second session, and authorized the construction of the Clark Hill Reservoir on the Savannah River in Georgia and South Carolina at an estimated cost, revised in 1951, of $77,- 000,000. The latest (1950) approved estimate for annual cost of maintenance and operation is $392,000. The Clark Hill Reservoir is on the Savannah River, Ga. and S. C., about 22 miles upstream from Augusta, Ga. The dam will have a total length of 5,680 feet, consisting of a concrete section 2,282 feet long with a maximum height of 200 feet, and a con- trolled-spillway section 1,096 feet long. The concrete section will be flanked on the west by a rolled-earth embankment extend- ing 2,069 feet to the abutment, and on the east by a similar embankment 1,329 feet long. The reservoir will have a total storage capacity of 2,900,000 acre-feet, of which 390,000 acre- feet will be reserved for flood control and 1,340,000 acre-feet will be used for the storage of water for generating hydroelectric power. The power installations will consist of seven generating units of 40,000 kilowatts each, a total of 280,000 killowatts. Local cooperation. None required. Operations and results during the fiscal year. The intake section of the concrete dam was completed in November 1950. Closure of the spillway section, begun in September, was com- pleted to the crest at elevation 300 feet in May 1951. Six of the 22 piers surmounting the spillway were completed, and the re- maining piers were well advanced. Both embankments were FLOOD CONTROL--SAVANNAH, GA., DISTRICT 571 completed except for stone protection on the upstream slope of the east embankment. A total of 339,000 cubic yards of con- crete was placed in the structure. Penstock intake gates, with operating machinery, were in- stalled. All tainter-gate anchorages were installed as concreting progressed. Two contracts for clearing 39,725 acres of the reservoir area were awarded. A total of 22,800 acres of clearing was completed. All remaining land required for the project was acquired in fee simple or placed under condemnation. Contracts for relocating power lines of the Georgia Power Co. and State highways in South Carolina were awarded. Negotia- tions were started for other utility and railroad relocations. Several hundred graves in the lower elevations of the reservoir area were moved. A contract for the power house was awarded in November. The contractor completed his construction plant, prepared the rock foundation, and placed concrete for four of the seven powerhouse units to the elevation of the draft tube flow line. The concrete cable tunnel from the powerhouse to the switch- yard was completed. With the exception of the switchyard contract, and reloca- tions contracts now under negotiation, all major contracts have been awarded. The total cost of new work during the year was $17,860,- 994.38. Expenditures amounted to $17,375,354.47. Conditions at end of fiscal year. The project, commenced in November 1945, was 64 percent completed. Of the total of 164,312 acres of land required for the project, 157,153 had been acquired, and the right of entry obtained for the remainder. All contracts for clearing the reservoir area, totaling 65,140 acres, were completed or under way, and a total of 36,314 acres had been cleared. With the exception of the spillway piers, tainter-gate and operating-machinery installation, and roadway, the concrete dam was essentially complete, as were the embankments. The construction plant for the powerhouse was completed, and foundation concrete placed for draft tubes in four of the seven generating units. The cable tunnel to the switchyard was completed. Work remaining to be done consisted of completing legal action for acquiring land under condemnation; completing existing contracts for the dam, powerhouse, generating units, and acces- sory electrical and mechanical equipment; placing of contracts for the switchyard and a few minor procurement features; hired labor operations for the provision of reservoir-management facilities; and such operational activities as will be necessary during the construction of the project. The total cost to June 30, 1951, was $49,087,738.18, and total expenditures amounted to $47,019,933.34. 572 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Proposed operations.

ATLANTIC INTRACOASTAL WATERWAY BETWEEN NORFOLK, VA., AND THE ST. JOHNS RIVER, FLA. (JACKSONVILLE DISTRICT) Location. This section includes that part of the Intracoastal Waterway between the southerly limit of Fernandina Harbor, Fla., at the junction of Lanceford Creek and Amelia River, and the St. Johns River, Fla. (See U. S. Coast and Geodetic Survey Chart No. 577.) (For Beaufort, S. C., to Cumberland Sound sec- tion, see p. 543.) Previous projects. The first project for the improvement of that part of the waterway was authorized by the River and Harbor Act of May 23, 1828, and modified by River and Harbor Act of June 23, 1874. For further details see Annual Report for 1915, page 1823, and Annual Report for 1938, page 605. Existing project. This provides for dredging and maintaining a channel 12 feet deep, with widths of 90 feet in land cuts and narrow streams and 150 feet in open waters, following in general the alinement of the existing waterway from Fernandina Harbor to St. Johns River, about 21.9 miles, with a cutoff in Kingsley Creek just north of the Seaboard Air Line Railroad bridge, and with such additional cutoffs or other changes in the adopted route as may be found desirable and justified by the resultant benefits to navigation. The mean range of tide is 6 feet at Fernan- dina and 3.8 feet in the St. Johns River, with fluctuations from 1.5 to 3 feet, due to winds and lunar phases. The actual cost of new work was $263,659.41 exclusive of amounts expended under previous projects. The latest (1951) approved estimate for annual cost of maintenance is $13,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 4, 1913 For a channel 100 feet wide and 7 feet deep..--------- H.

Local cooperation. Fully complied with as to original construc- tion. The River and Harbor Act approved June 20, 1938, included the requirement that local interests furnish spoil-disposal areas for subsequent maintenance as may be required. The Florida Inland Navigation District, a special taxing district empowered by Florida State law to comply with features of local cooperation, has furnished rights-of-way and spoil-disposal easements for maintenance dredging to provide for the rectification of the chan- nel alinement and has furnished temporary spoil-disposal areas as and when needed. By letter dated June 12, as modified by letter dated December 6, 1944, the district engineer requested the Florida Inland Navigation District to furnish spoil-disposal areas in perpetuity adequate for a 25-year maintenance program. The Navigation District has furnished a considerable number of the RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 577 required spoil-disposal areas, and others are being furnished at a satisfactory rate. Terminal facilities. There are no terminal facilities along this section of the Intracoastal Waterway. Operations and results during fiscal year. Periodic condition surveys and inspections cost $438.87 for maintenance. The ex- penditures were $185.89. Condition at end of fiscal year. A 7-foot channel was dredged between October 1913 and February 1915, and was deepened to 12 feet with present authorized widths between November 1940 and September 1941, thereby completing the existing project. The length of the waterway was reduced 2.4 miles between May and October 1943 by making five cutoffs and widening bends at three localities. To safeguard navigation through bridge openings and to permit breaking tows when tidal conditions are adverse, 14 protective and 10 tie-up dolphins have been constructed at the Sisters Creek bridge at the southerly entrance to the waterway, and 8 protective and 10 tie-up dolphins have been constructed at the Kingsley Creek bridges, about 4 miles south of Fernandina. At the Kingsley Creek bridges, three of the four center protective dolphins-one on the north side and two on the south side-have been destroyed. At the end of the fiscal year the controlling depth was about 6.4 feet in midchannel for half project width and 7.3 feet and 2.6 feet in the easterly and westerly outside quarters, respectively. The costs of the existing project have been $263,659.41 for new work and $773,103.13 for maintenance, a total of $1,036,- 762.54. The expenditures have been $1,036,509.56. Proposed operations. The balance unexpended June 30, 1951, $3,500, plus an allotment of $45,000 during the fiscal year 1952, a total of $48,500, will be applied as follows: Accounts payable June 30, 1951 ............................ $252.98 Maintenance: Dredge, by contract, to remove shoaling from 9 shoal areas to a depth of 12 feet, November 1951 ..................................... $45,400.00 Complete hired-labor survey to determine the condition of the project channel, July and August 1951 ............................. 2,847.02 48,247.02 Total for all work............................... 48,500.00 No work is scheduled for fiscal year 1953. 578 REPORT OF CHIEF OF ENGINEERS, U.

JACKSONVILLE HARBOR, FLA. Location. The St. Johns River rises in the marshes of Brevard County, Fla., near the east coast, and flows northwesterly to Jack- sonville, thence easterly into the Atlantic Ocean, 122 miles south of Savannah River. Its total length is about 285 miles. (See U. S. Coast and Geodetic Survey Chart No. 577.) Previous projects. Six appropriations for surveys and experi- mental dredging on the bar were made from 1852 to 1878. Proj- ects for permanent improvement were adopted by the River and Harbor Acts of June 14, 1880, and June 3, 1896. For further de- tails see page 1823, Annual Report for 1915, and page 607, An- nual Report for 1938. Existing project. This provides for: (a) A channel 34 feet deep from the ocean to Commodore Point via a cutoff channel from St. Johns Bluff (Fulton) to Dame Point and via Terminal Channel along the west bank of the river just below Commodore Point, and thence 30 feet to the Florida East Coast Railway bridge at Jacksonville, with widths of 800 feet at the entrance and between the jetties, from 900 to 1,200 feet in Pilot Town Cut, from 1,050 to 1,335 feet in Mayport Cut, generally 500 feet in the St. Johns Bluff - Dame Point Cutoff, a maximum of 1,450 feet at Dame Point, 590 feet in Terminal Channel (with the westerly edge 60 feet from the new pierhead-bulkhead line), from 400 to 900 feet in other cuts, increasing to as much as 1,115 feet at bends, and 300 feet in Arlington Cut, which is 30 feet deep and generally parallel to Terminal Channel; (b) a depth of 24 feet between that depth contour and the pierhead line at Jacksonville from Hogan Creek to the foot of Laura Street; (c) a depth of 28 feet to within 60 feet of the pierhead line in the area between the foot of Laura Street and the St. Elmo W. Acosta Bridge (formerly Duval County highway bridge) ; (d) a navigation and floodway channel 26 feet deep and 200 feet wide along the south side of the Commodore Point terminals, terminating in deep water at each end; (e) an approach and mooring basin 20 feet deep, 1,300 feet long at the 20-foot depth contour and 600 feet long at the pierhead line, in front of the Naval Reserve Armory in South Jacksonville; and (f) construction of training walls and revetments. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 579 All depths are referred to local mean low water. No dredging is to be done within 60 feet of a pierhead line, except at the Naval Reserve Armory. Natural depths of 34 feet or more, for adequate width, exist in midchannel from Commodore Point to the Florida East Coast Railway bridge at Jacksonville. Two converging rubblestone jetties, built at the entrance under a previous project, are maintained under the existing project. The north jetty is 14,300 feet long and the south jetty 11,183 feet long. The jetties are parallel and 1,600 feet apart for 4,022 feet from the sea ends. Stone training walls have been built at seven localities, involving about 7 miles of this class of structure. Stone revetments at five localities provide about 3.5 miles of shore pro- tection. The training walls and revetments are located between Dame Point and Wards Bank, near the inner ends of the jetties. The length of section included in the project is 26.1 miles via the cut-off channel. The mean tidal range is 5.3 feet on the bar, 4.5 feet at Mayport, 2.6 feet at Dame Point (12 miles above the entrance), and 1.1 feet at Jacksonville (St. Elmo W. Acosta Bridge). The extreme range varies from about 9 feet on the bar to about 1.5 feet at Jacksonville. Strong northeasterly winds raise the water level about 2 feet at Mayport and Jacksonville. Strong southwesterly winds lower the water about 1.5 feet at Mayport and 1 foot at Jacksonville. The estimate of cost for new work, approved in 1951, is $11,- 825,000 exclusive of amounts expended on previous projects. The latest (1951) approved estimate for annual cost of maintenance is $300,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents ST.

All work authorized by the River and Har- bor Act of March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, ease- ments, and rights-of-way and spoil-disposal areas for the initial work and for subsequent maintenance when and as required, and hold and save the United States free from claims for damages resulting from the improvement. It is provided that these require- ments as to the 28-foot-depth dredging between the foot of Laura Street and the St. Elmo W. Acosta Bridge and the dredging in front of the Naval Reserve Armory may be waived or modified if in the discretion of the Chief of Engineers such action is neces- sary in the interest of national defense (H. Doc. 322, 77th Cong., 1st sess.). The deepening of the improvement to 34 feet is subject to the additional requirement (S. Doc. 230, 78th Cong., 2d sess.) that local interests give assurances satisfactory to the Secretary of War that they will modify terminal facilities as necessary to permit full utilization of the deeper channel. A resolution adopted January 4, 1946, by the Jacksonville Chamber of Commerce, agreeing to comply with the above-mentioned features of local cooperation, was accepted by the Secretary of War on February 11, 1946, as satisfactory assurance of compliance. All spoil-dis- posal areas and rights-of-way required in connection with the new-work dredging between Commodore Point and the ocean and for cutoff channel have been furnished. Terminal facilities. There are 81 piers and wharves serving the water-borne commerce of the port. The depths of water vary from 31 feet at the larger terminals to a few feet at the inner end of the slips and at barge berths. The Jacksonville municipal terminals at Talleyrand Avenue consist of three piers. There are 35 other piers and wharves used for handling the water-borne commerce of the port or mooring vessels, 11 of which are open to the public. All have railway and highway connections except nine of the smaller piers, which have highway connections only. Of the remaining piers, 26 are used in connection with shipyards and marine repair plants, 2 for recreational craft, 8 for industrial purposes, and 7 are not used. In addition, privately operated piers and wharves are available at Mayport, Fla., to serve the fishing industry, and facilities for servicing recreational craft are avail- able at Fulton. The facilities are considered adequate for existing RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 581 commerce. (See Port Series No. 15, revised 1947, Corps. of Engi- neers.) Operationsand results during fiscal year. New work: Dredg- ing, under continuing contract, to provide the 34- by 500-foot Dame Point-St. Johns Bluff (Fulton) Cutoff, begun July 10, 1950, were 89 percent completed at the end of the fiscal year. Contract dredges Barlow and Philadelphia removed 15,276,136 cubic yards of material and placed 34,134 cubic yards of oystershell and stone in structures at a cost of $1,749,894.51. Dredging under contin- uing contract to deepen to 34 feet the channel between St. Johns Bluff (Fulton) and Mayport, begun June 2, 1951, was 32 percent completed at the end of the fiscal year. Contract dredge Barlow removed 481,385 cubic yards at a cost of $238,207.38. Dredging, with the United States hopper dredge Comber, to deepen to 34 feet the channel between Mayport and the Ribault Bay entrance channel, begun April 19, 1951, was 67 percent completed at the end of the fiscal year. There were removed 1,846,895 cubic yards, bin measurement, at a cost of $217,106.14. Preliminary survey plans and specifications for the entire project cost $5,683.65. A survey between Commodore Point and Dame Point cost $2,557.78. Additional compensation allowed contractor for work completed in a prior year cost $26,719.63. Maintenance: The leased dredge Congaree removed 163,165 cubic yards of material from shoals in Fulton Cut between No- vember 22 and December 30, 1950, at a cost of $46,260.35. Periodic condition surveys and inspections, and surveys to relocate and reestablish Jacksonville harbor-line reference monuments, cost $7,716.35. The total costs for the year were $2,240,169.09 for new work and $53,976.70 for maintenance, a total of $2,294,145.79. The expenditures were $1,899,606.49. Condition at end of fiscal year. The existing project was about 87 percent completed. Dredging was begun about November 1910. A channel at least 30 feet deep and of practicable width from the entrance to Jacksonville was completed in March 1922. Widening the 30-foot channel to authorized widths was completed in July 1937, except Terminal Channel, which was only 400 feet wide. Deepening the existing channels to 34 feet was begun in July 1947, and has been completed between Commodore Point and Dame Point, including widening Terminal Channel to 575 feet. The Dame Point-Fulton Cutoff was opened to traffic June 1, 1951. A depth of 24 feet between the 24-foot contour and the pierhead line at Jacksonville from Hogan Creek to the Florida East Coast Railway bridge was provided between October 1907 and January 1912. The two jetties at the entrance, constructed under a previous project between December 1880 and June 1904, have been maintained under the existing project. About 3,555 linear feet of the inner end of the north jetty has been capped with concrete. All training walls and revetments now considered necessary were constructed by Duval County between July 1892 and May 1894, and by the United States under the former and the existing project intermittently between October 1903 and 582 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 September 1927. The easterly end of the Wards Bank training wall has been revetted with granite riprap. Material dredged in the vicinity of the westerly end of Bar Cut and deposited ad- jacent to and on the north side of the north jetty in the vicinity of the Fort George River encroachment has effectively prevented further erosion adjacent to that structure. The jetties are in generally fair condition except as follows: The capstone has been displaced by sea action in the outer 800 feet of the south jetty, the outer 300 feet of the north jetty, and at isolated locations in both jetties; and erosion has occurred at the inner end of the north jetty from the high-water shore line to a point about 1,000 feet west of the existing monolithic concrete cap. Revetments and training walls are in generally fair condition, but four of the training walls are in poor condition. Low places of varying lengths are submerged during high tide, and complete breaks exist in other training walls. Wards Bank training wall has been reinforced by the Navy Department around its easterly end with heavy capstone. The controlling depths in the middle half of the existing chan- nels were as follows: Bar Cut range, 33.0 feet (November 1950) ; thence to Dame Point, 30.5 feet at Fulton Cut range (December 1950) ; thence to Jacksonville, 34 feet except for shoaling in the middle section of Terminal Channel with a limiting depth of 30.2 feet (June 1951) ; and Arlington Cut and city limits range, 26.5 feet (November 1948). The limiting depth in the left and right outside quarters of the channels from the ocean to Jackson- ville was 12.9 feet at Pilot Town Cut range. A controlling depth of 24 feet was available up to the pierhead line between Hogan Creek and the foot of Laura Street in 1934, and to within 60 feet of the pierhead line thence to the St. Elmo W. Acosta Bridge in 1938. The work remaining to be done to complete the project is as follows: Complete dredging the cutoff channel from Dame Point to St. Johns Bluff (Fulton) and the existing channel from Fulton to the ocean; dredge the area between the foot of Laura Street and the St. Elmo W. Acosta Bridge to a depth of 28 feet; dredge the navigation and floodway channel along the south side of Commodore Point terminals, and dredge the approach and mooring basin in front of the United States Naval Reserve Armory. The total cost of the existing project, all funds, has been $20,- 933,513.71 of which $10,503,854.37, including $290,013.37 Public Works funds, was for new work, and $10,429,659.34 for main- tenance. The expenditures have been $20,532,112.82, including $290,013.37 Public Works funds. Proposed operations.

Existing project. This provides for a channel 13 feet deep and 200 feet wide from the Florida East Coast Railway bridge at. Jacksonville to Palatka (54.5 miles), thence 12 feet deep and 100 feet wide to Sanford (86.1 miles), with a side channel of like dimensions to Enterprise and with cutoffs and easing of bends, and thence 5 feet deep and 100 feet wide to Lake Harney (20.9 miles), with a cutoff channel 5 feet deep and 75 feet wide be- tween Lake Monroe and the vicinity of Osteen Bridge; and for a channel 8 feet deep, 100 feet wide across the bar at the mouth of Deep Creek, and thence 50 feet wide to Hastings Landing, 5 miles above the mouth. The plane of reference is local mean low water. The length of the project is 161.5 miles in the St. Johns River, 5 miles in Deep Creek, 2.7 miles in the approach channel to Enterprise, and 0.9 mile in the alternative approach channel to Sanford. Two pile-and-stone jetties at Volusia Bar at the head of Lake George, built under a previous project, are maintained under the existing project. The jetties are 3,400 and 2,200 feet long, respectively. The mean tidal range is 1.1 feet at Jacksonville and 1.2 feet at Palatka. At low-water stages, tidal influence is perceptible at Sanford, 140.6 miles above Jacksonville, and upstream currents are sometimes noticeable as far as Lake Harney. The extreme tidal range is about 1.5 feet at Jacksonville and 2 feet at Palatka. Brisk northerly and northeasterly winds raise the water level about 2 feet at Jacksonville and 1 foot between Palatka and San- ford. Brisk southerly and southwesterly winds lower it about 1 foot between Jacksonville and Sanford. Flood stages in the river usually occur during the fall; and the usual maximum is about 2 feet at Palatka, 3 feet at Lake George, 8 feet at Sanford, and 9 feet at Lake Harney. The estimate of cost for new work, approved in 1951, is $1,- 282,600, exclusive of amounts expended on previous projects. The latest (1951) approved estimate for annual cost of maintenance is $27,000.

All requirements prior to those imposed by the River and Harbor Act approved March 2, 1945, have been fully complied with. The requirements imposed by that act and the River and Harbor Act approved July 24, 1946, have been fully complied with as regards new work except for furnishing rights-of-way and spoil-disposal areas for the Beresford cutoff, which is not to be provided at this time. Those acts imposed the requirement, among others, that local interests furnish, free of cost to the United States, suitable spoil-disposal areas for subse- quent maintenance. The cutoff channel between Lake Monroe and the vicinity of Osteen Bridge (H. Doc. 445, 78th Cong., 2d sess.) is subject to the additional requirement that local interests agree to hold and save the United States free from any damages result- ing from this work. Deepening to 12 feet between Palatka and Sanford and in the branch to Enterprise (S. Doc. 208, 79th Cong., 2d sess.) is subject to the additional requirement that responsible local interests will give assurances satisfactory to the Secretary of War that they will provide and maintain, with- out cost to the United States, adequate terminal facilities, when and as required, which shall be open to all on equal terms. A resolution adopted July 5, 1945, by the Board of County Commissioners for Seminole County, agreeing to comply with the conditions imposed by House Document No. 445, Seventy-eighth Congress, second session, was accepted by the Secretary of War on October 3, 1945, as satisfactory assurance of compliance. Local interests at Sanford have indicated that they will construct addi- tional terminal facilities when and as required by the traffic on the waterway. The present facilities are considered adequate for the existing commerce. 586 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Terminal facilities. There are ample wharves and terminals at Jacksonville and about 24 piers and wharves at various points on the river above Jacksonville. These include the following: Municipal piers or wharves at Mandarin, Green Cove Springs, Federal Point, and Palatka; a municipal recreational pier at San- ford; and six privately owned piers at Palatka, five at Sanford, and eight at other points along the river between Palatka and Sanford. Five of the private piers have nearby tank storage for petroleum products as follows: One at Palatka, one at Lake Mon- roe, one at Enterprise, and two at Sanford. All piers have high- way connections and one at Palatka has railway connections. In addition, there are a number of small, privately owned piers and wharves for recreational craft at various points along the river. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Repair, by contract, of the existing guide-fender system at Volusia Bar, 34 percent completed at the beginning of the fiscal year, was completed September 1, 1950. The cost was $19,896.87 for maintenance. The expenditures were $26,067.33. Condition at end of fiscal year. The existing project is about 90 percent completed. Dredging between Jacksonville and Palatka was begun in April 1900 and completed in November 1915 except for the work in Deep Creek, which is about 50 percent completed. In 1939, the Department of the Navy deepened the channel be- tween Jacksonville and the United States naval air station at Black Point to 18 feet. A channel 8 feet deep and 100 feet wide from Palatka to Sanford, including side channel to Enterprise, was dredged between February 1911 and June 1923, except for making three cutoffs, which were completed in June 1935, and easing a number of bends. Deepening that channel to 12 feet, in- cluding the side channel to Enterprise, and easing a number of bends was begun in August 1947 and completed in October 1948. A channel 5 feet deep and 100 feet wide from Sanford to Lake Harney was dredged between November 1911 and March 1912, and a cut-off channel 5 feet deep and 75 feet wide between Lake Monroe and the vicinity of Osteen Bridge was dredged during February and March 1948. Two converging pile-and-stone jetties at Volusia Bar at the head of Lake George, built under a previous project between December 1880 and May 1887, have been main- tained under the existing project. When last surveyed, controlling depths were as follows: Jack- sonville to the United States naval air station, 18 feet for project width in 1939; thence to Palatka, 9.7 feet in the middle 100-foot width of channel at Federal Point, with 11.2 feet available in the easterly half of the channel, in October 1945; from Palatka to Sanford, 12 feet, based on surveys between November 1947 and May 1949; Enterprise side channel, 12 feet in February 1948; and Sanford to Lake Harney, 7 feet in the Woodruff Creek cut-off and 4.2 feet in midchannel elsewhere, with a limiting edge depth of 2.5 feet, April 1949; and at the entrance to Deep Creek, 7 feet, date of survey unknown. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 587 The work remaining to be done to complete the project is as follows: Dredging a cutoff channel across Beresford Peninsula, and completing two cutoffs and easing five bends in Deep Creek. The costs and expenditures under the existing project have been $1,141,676.66 for new work and $430,018.69 for mainte- nance, a total of $1,571,695.35. Proposed operations. No work is scheduled during the fiscal year 1952. The sum of $2,500 can be profitably expended for maintenance during the fiscal year 1953 in making a condition survey of the project channels between Palatka and Sanford.

The estimated cost of new work, approved in 1951, is $92,815,- 200, with $323,000 annually for maintenance and operation. The project was authorized by Public Law 675, Seventy-seventh Congress, approved July 23, 1942 (H. Doc. 109, 79th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. The project provides that local interests furnish, without cost to the United States, all lands, easements, and rights-of-way necessary for the construction of the canal; hold and save the United States free from damages due to con- struction works; and take over, maintain, and operate all high- way bridges and roadways built in connection with the project. Operations and results during fiscal year. Expenses incidental to the administration of real estate pertaining to the project were $1,093.61. The costs for the year were $1,093.61, all for new work. The expenditures were $1,411.38. Condition at end of fiscal year. Work on the project has been limited to detail planning, including surveys and preparation of detailed plans, specifications, and a definite project report. The buildings and grounds at the United States reservation at Camp Roosevelt, near Ocala, Fla., provided in 1935 in connection with the Atlantic-Gulf Ship Canal, were maintained until September 1946 when the Federal Public Housing Authority took over cer- tain buildings and grounds and the operation of utilities. The buildings and grounds retained by the Corps of Engineers were maintained from that date through June 1950. Periodic ground- water observations, stream gaging, and the operation of meteoro- logical instruments were in progress continuously between No- vember 1935 and April 1950 except during December 1946. The total cost and expenditures have been $1,465,080.57, all for new work. Proposed operations. No work is scheduled for the fiscal years 1952 and 1953.

OKLAWAHA RIVER, FLA. Location. This river has its source in the system of large lakes in the central part of the Florida peninsula and flows generally northerly, then easterly, emptying into the St. Johns River 22 miles above Palatka. The extreme head of the system may be taken as Lake Apopka, 120 miles above the mouth of the river. Previous projects. The first improvement was authorized by an act of Congress approved February 24, 1835. For further de- tails see page 1825, Annual Report for 1915, and page 613, Annual Report for 1938. Existing project. This provides for deepening the channel to 6 feet at mean low water from the mouth to the head of Silver Springs Run, 57.7 miles; for clearing the channel of obstructions from Silver Springs Run to Lake Griffin, including the Kyle and Young Canal and its extension to Morrisons Landing and the J. D. Young Canal from Morrisons Landing to Starkes Ferry (clear title to the canals and sufficient land adjacent thereto to provide for future widening has been conveyed to the United States) ; and for maintaining the dikes with a view to obtaining a navigable depth of about 4 feet to Leesburg, 85.7 miles above the mouth. The work embraces dredging, snagging, making cut- offs at sharp bends, removing overhanging trees and obstructive aquatic vegetation and constructing a lock and dam at Moss Bluff to maintain the water level in Lake Griffin.

There are numerous privately owned land- ings along this river, more or less out of repair, and a muncipal wharf at Leesburg; no charges for wharfage. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Peri- odic inspections of the upper and lower river and the gages were made. During the inspections numerous trees, timber, treetops, and minor obstructions to navigation were removed. The cost was $1,782.89. Operating and care: The lock and dam at Moss Bluff were operated and maintained. Buildings and grounds were cared for with United States plant and hired labor. The costs were $13,- 935.44 for operation and $284.33 for ordinary repairs, a total of $14,219.77. The costs for the year were $1,782.89 for maintenance and $14,219.77 for operating and care, a total of $16,002.66. The ex- penditures were $16,449.04. Condition at end of fiscal year. The existing project was about 72 percent completed. By dredging, making cut-offs, and snag- ging intermittently between January 1892 and June 1914, a clear RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 591 channel with a depth of about 6 feet at ordinary stages was obtained to a point about 32 miles above the mouth and thence about 4 feet deep to the head of Silver Springs Run, 57.7 miles above the mouth. A channel 4 feet deep at mean low water and 30 feet wide between Silver Springs Run and Moss Bluff lock was dredged between late 1924 and November 1929. A lock and dam at Moss Bluff were constructed between about March 1923 and late 1925. For further details relative to this lock see para- graph "Existing project." The United States reservation com- prises 13.14 acres of land, two dwellings, a storehouse, and other small buildings. Most of the original dredging of the canal be- tween Heather Island (6.3 miles above the mouth of Silver Springs Run) and Starkes Ferry near Lake Griffin was done by private interests between 1911 and 1923. Between June 1929 and June 1930, the canal between Moss Bluff lock and Starkes Ferry was enlarged to 8 feet deep by 50 feet wide to provide for control of Lake Griffin. The dike on the east side of the canal was re- paired and improved as a maintenance feature from June to December 1936. At the close of the fiscal year, the river was in fair condition, the lock and dam were in fair condition, and the canals and dikes above the lock were in fair condition. In June 1951, the control- ling depths were about as follows: Mouth of the river to Silver Springs Run, 3.5 feet; Silver Springs Run, 6 feet; Silver Springs Run to Moss Bluff lock, 5 feet; and thence to Leesburg, 6.5 feet. The work remaining to be done to complete the project consists of easing several sharp bends and obtaining project dimensions in the section between the mouth of the river and the mouth of Silver Springs Run, which is not considered necessary at this time. The costs of the existing project have been $311,352.45 for new work, $336,983.73 for maintenance, and $156,799.08 for operat- ing and care, a total of $805,135.26. The expenditures have been $805,175.02. In addition, $11,414.41 were expended between August 1, 1929, and June 30, 1935, on the operation and care of the works of improvement under the provisions of the perma- nent indefinite appropriation for such purposes. Proposed operations.

INTRACOASTAL WATERWAY, JACKSONVILLE TO MIAMI, FLA. Location. The waterway extends from Jacksonville to Miami, Fla., following the St. Johns River to the mouth of Pablo Creek, 23 miles, and thence following in general the line of a canal con- structed by the Florida Coast Line Canal & Transportation Co. (See U. S. Coast and Geodetic Survey Charts Nos. 842-847.) Previous projects. Adopted by River and Harbor Acts of June 15, 1844, July 13, 1892, August 18, 1894, and Deficiency Act of February 26, 1896. For further details, see page 1825, Annual Report for 1915; page 655, Annual Report for 1926; and page 618, Annual Report for 1938. Existing project. This provides for an inland waterway 12 feet deep at local mean low water and generally 125 feet wide from Jacksonville to Miami, with such modifications in cut-off and other questions of alinement as may be required by the Chief of Engineers; for a turning basin 8 feet deep, 400 feet wide, and 800 feet long in the vicinity of Jacksonville Beach, Fla.; for an entrance channel 8 feet deep and 100 feet wide from the Intra- coastal Waterway to and including a turning basin of the same depth, 300 feet wide and 600 feet long, at Sebastian, Fla.; and for a basin 8 feet deep extending from the Intracoastal Waterway to the easterly shore, about 1,140 feet wide at the waterway and 280 feet wide at the shore line, at or near Vero Beach, Fla. The length of the waterway is 370 miles, of which 21 miles are in- cluded in the project for improvement of Jacksonville Harbor, Fla. The project also includes the operation and maintenance of the bridge near Palm Valley, the title to which was passed to the United States, along with all other property of the Florida Coast Line Canal & Transportation Co., under the conditions of local cooperation. The mean range of tide is 3.8 feet at the St. Johns River, 0.7 foot in the Indian River at Fort Pierce, 1.8 feet in Lake Worth at the Port of Palm Beach terminals, 2.3 feet at the Port Everglades terminals, and 2 feet in Biscayne Bay. The extreme range is about 7 feet at the St. Johns River, 1.5 feet at Fort Pierce, and 3 RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 593 feet in Biscayne Bay. Tidal effect is imperceptible at points along the waterway distant from inlets. The estimate of cost for new work, approved in 1951, is $25,- 774,400, exclusive of amounts expended on previous projects. The latest (1951) approved estimate for annual cost of maintenance is $322,000, including $16,000 for the operation and care of the bridge near Palm Valley.

Local cooperation. The conditions imposed by the River and Harbor Acts approved January 1, 1927, and July 3, 1930, have been fully complied with, including furnishing suitable spoil- disposal areas for subsequent maintenance of the improvement as and when required. Subsequent acts authorizing enlargement of the waterway have imposed the same requirement with respect to spoil-disposal areas for maintenance. The Florida Inland Navigation District, a special taxing district empowered by State law to comply with certain features of local cooperation, was re- quested to furnish additional spoil-disposal areas in perpetuity for a 25-year maintenance program in the southerly and north- erly halves of the waterway on May 15 and July 1, 1944, respec- tively. Numerous areas have been furnished and the Navigation District is actively engaged in securing other areas by negotia- tion or, when necessary, by condemnation. The areas are being furnished at a satisfactory rate. Temporary spoil-disposal areas for maintenance have been and are being furnished as and when required. The work authorized by the River and Harbor Act of August 26, 1937, is subject to the condition that local interests provide, free of cost to the United States, all lands and rights-of-way necessary for the improvement and for its subsequent mainte- nance when and as required, and to the further condition that local interests provide, without cost to the United States, suitable highway connections and a bulkhead along the south side of the basin on plans approved by the Chief of Engineers, and agree to maintain said bulkhead and the land approaches thereto as a pub- lic terminal open to all on equal terms. A resolution adopted by the city council of Jacksonville Beach, Fla., agreeing to comply with those conditions, was accepted by the Chief of Engineers on October 18, 1945, as satisfactory assurance of compliance. The 594 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 lands needed for rights-of-way and spoil-disposal have been fur- nished. A highway from Jacksonville to Jacksonville Beach, opened to traffic on December 14, 1949, satisfies the requirements as to highway connections. All work authorized by the River and Harbor Act of March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, and rights-of- way and spoil-disposal areas for new work and for subsequent maintenance, when and as required, and hold and save the United States free from claims for damages resulting from the improve- ment. The act imposed additional requirements as follows: (a) Deepening the waterway to 12 feet is subject to the conditions (H. Doc. 740, 79th Cong., 2d sess.) that local interests bear the cost of all alterations of bridges, cables, pipelines, and other structures made necessary by the improvement and that, if for any cause the Secretary of War finds it advisable, he may cause proceedings to be instituted in the name of the United States for acquirement by condemnation or otherwise of any lands, ease- ments, rights-of-way, and spoil-disposal areas needed for the im- provement, after receipt of assurances satisfactory to him from responsible local agencies that they will reimburse the United States for the costs; (b) provision of a side channel at Sebastian is subject to the condition (H. Doc. 336, 76th Cong., 1st sess.) that local interests give assurances satisfactory to the Secretary of War that they will provide and maintain suitable terminal fa- cilities open to all on equal terms; (c) provision of the basin at Vero Beach is subject to the requirements (H. Doc. 261, 76th Cong., 1st sess.) that local interests furnish assurances satis- factory to the Secretary of War that they will protect the shore line with an adequate bulkhead, and provide, maintain, and oper- ate terminals adequate to full utilization of the improvement, open to all on equal and reasonable terms. A resolution adopted August 2, 1946, by the Florida Inland Navigation District was accepted by the Chief of Engineers De- cember 24, 1946, as satisfactory assurance that the Navigation District will furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas needed for new work and subsequent maintenance when and as required, and will hold and save the United States free from damages resulting from the construction and maintenance of the 12-foot project. The Navigation District assumes no responsibility for the addi- tional requirement that local interests bear the cost of all altera- tions of bridges, cables, pipelines, and other structures made necessary by the improvement (H. Doc. 740, 79th Cong., 2d sess.), as it is not empowered by State law to comply with such features of local cooperation. The bridges, cables, pipelines, and other structures are owned by various individuals and public and private corporations. Most of those structures were constructed under permits issued by or under authority of the Secretary of War. Alteration of all bridges, cables, pipelines, and other struc- tures, made necessary by the improvement, can properly be re- quired of the owners under existing Federal law. Procurement by RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 595 the Navigation District of the required rights-of-way and tem- porary spoil-disposal areas for new work is virtually complete for some sections of the waterway, and is well advanced and actively in progress in others. The Navigation District states that it is in a position to furnish all remaining areas in a short time after it is evident that funds will become available. No delays due to lack of suitable rights-of-way and spoil-disposal areas, nor to alterations of bridges, cables, pipelines, and other structures made necessary by the improvement, are expected. A resolution adopted by the City of Vero Beach on August 8, 1945, agreeing to comply with the features of local cooperation pertaining to the basin at Vero Beach, was accepted by the Secre- tary of War on November 28, 1945, as satisfactory assurances of compliance. On March 14, 1946, local interests were informed as to the requirements imposed in connection with the provision of a side channel at Sebastian, but no assurance of compliance with those requirements has been received. Local interests have stated that participation by them in meeting local cooperation require- ments is contingent upon the prior opening of Sebastian Inlet. Terminal facilities. Extensive terminals with railway and street connections are available at Jacksonville and Miami. Ter- minals, with railway and highway connections, for coastwise vessels have been constructed at Fort Pierce (Indian River), Riviera (Lake Worth), and Port Everglades Harbor. Municipal piers or wharves have been constructed at Titusville, Courtenay, Cocoa, Melbourne, and Vero Beach for handling general freight, and at St. Augustine, Daytona Beach, New Smyrna Beach, Eau Gallie, West Palm Beach, and Miami for the use of recreational craft. At Daytona Beach, Titusville, Eau Gallie, and Fort Pierce, yacht basins open to the public have been provided. They are connected with the Intracoastal Waterway by channels 6 to 8 feet deep and 80 to 100 feet wide. At Fort Pierce a channel 6 feet deep and 80 feet wide has been dredgd by the United States from the Intracoastal Waterway to and up Taylor Creek to the U. S. Coast Guard buoy depot. There are also a number of privately owned piers, wharves, and landings at various points along the waterway. The facilities are considered adequate for the existing commerce. (For further details on facilities at Jacksonville, Fort Pierce Harbor, Port of Palm Beach, Port Everglades, and Miami, see Port Series Nos. 15 and 16, revised 1947, and Port and Terminal Facilities Report, 1941, Corps of Engineers.) Operations and results during fiscal year. New work: Dredg- ing, by contract, to deepen and widen to 12-foot depth and 125- foot width the section between the St. Johns River and vicinity of Palm Valley Bridge, which was begun with dredge No. 5 on June 19, 1951, was 7 percent completed at the end of the fiscal year. Removal of 144,115 cubic yards of material was accom- plished at a cost of $23,686.04. The definite project report, under preparation at the beginning of the fiscal year, was completed at a cost of $1,096.03.

The costs were $17,999.27 for operation, $1,- 060.46 for ordinary repairs, and $25.04 for improvement and reconstruction, a total of $19,084.77. The costs for the year were $126,642.58 for new work, $169,- 755.93 for maintenance, and $19,084.77 for operating and care, a total of $315,483.28. The expenditures were $239,013.75. Condition at end of fiscal year. The existing project was 30 percent completed. A channel 8 feet deep at local mean low water and 100 feet wide was dredged between March 1930 and May 1935. The present width of 100 feet is reduced at 52 localities by bridges, with a limiting horizontal clearance of 51 feet at the Deerfield Beach Bridge. A steel-and-concrete, double-leaf bascule highway bridge near Palm Valley, to replace the temporary pontoon bridge at that locality, was constructed between Septem- ber 1936 and July 1937 at a cost of $117,916.77. Dredging to enlarge the waterway to 12 by 125 feet was begun on the section between the St. Johns River and the vicinity of Palm Valley Bridge on June 19, 1951. When last surveyed at various times between September 1949 and May 1951, project depth existed except at isolated shoals where controlling depths were as follows: 6.2 feet over shoal near Pablo Creek Bridge extending 60 feet into channel from east side; 5.1 feet over shoals encroaching from both sides of channel at Oak Landing; 7.6 feet over shoal on east side of channel near Cook Landing; three minor shoals near former Monet Bridge site, none of which extend across the channel, 7.5 feet on the channel center line; a small shoal almost entirely across the channel at Riviera Bridge, 7.4 feet on channel center line; and shoals encroaching from both sides of channel south of Hillsboro Inlet, 8 feet on channel center line. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 597 The work remaining to be done to complete the project is as follows: Complete enlargement of the waterway to 12 by 125 feet; provide a turning basin near Jacksonville Beach; provide a side channel and a basin at Sebastian; and provide a basin at Vero Beach.

ST. AUGUSTINE HARBOR, FLA. Location. On the east coast of Florida, about 35 miles south of the entrance to St. Johns River and about 180 miles north of Fort Pierce Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 1243 and 1244.) RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 599 Previous projects. Appropriations were made by the acts ap- proved March 2, 1829, and June 27, 1834, for a survey of the har- bor and the bar at the entrance. The River and Harbor Act approved August 11, 1888, authorized improvement of the harbor subject to a subsequent report of a board of engineers. For fur- ther details see page 284, Annual Report for 1904, and page 623, Annual Report for 1938. Existing project. This provides for an entrance channel along the best natural alinement as it may exist from time to time, 200 feet wide and 16 feet deep at mean low water across the new inlet bar, thence 12 feet deep to the Intracoastal Waterway; for a sand-trap groin on the north side of the inlet and extending sea- ward from the ocean shore of Vilano Beach and a sand-tight jetty on the south side of the inlet extending seaward from the ocean shore of Conch Island (formerly Vilano Point or North Point) parallel to and coextensive with the groin; for future landward extension of the groin and jetty; and for a channel 10 feet deep and 100 feet wide in San Sebastian River from the Intracoastal Waterway to the King Street Bridge with a turning place near the upper end. Those improvements are subject to such modifica- tion as in the discretion of the Secretary of the Army and Chief of Engineers may be advisable. The length of the inlet channel is about 1.5 miles, and the length of the San Sebastian River channel about 2.6 miles. The sand-trap groin now on the north side of the inlet is 1,580 feet long, with a 300-foot landward extension at an angle of 450, constructed of granite, native rock, and creosoted timber. The south jetty is to be initially about 2,870 feet long. The groin and jetty are later to be extended landward, if necessary, to total lengths of 3,700 and 4,200 feet, respectively. The mean tidal range is 4.5 feet in the ocean at St. Augustine Inlet (the old inlet) and 4.2 feet at the city water front. A 10-foot tide above mean low water was recorded at the water front during a tropical storm in 1944 and again in 1950. The tidal range in San Sebastian River is about 4.5 feet; strong northerly winds, mostly in winter, lower the water surface about 1 foot. The estimate of cost of new work, revised in 1951, is $2,778,500 for the work at the new inlet and $64,000 for the channel in San Sebastian River, a total of $2,842,500, exclusive of amounts ex- pended on previous projects and $137,500 contributed by local ihterests. The latest (1951) approved estimate for annual cost of maintenance is $36,600, of which $3,800 is for maintenance of the San Sebastian River channel. The existing project was authorized by the following river and harbor acts: 600 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Acts Work authorized Documents June 20, 1938 For a straight entrance channel 27 feet deep and 200 H.

Local cooperation. The work authorized by the River and Harbor Act of May 17, 1950, is subject to the condition that local interests furnish without cost to the United States all lands, easements, and rights-of-way necessary for construction and maintenance of the project, when and as required, and agree to hold and save the United States free from all claims for damages due to construction and maintenance of the works. All prior requirements have been fully complied with. Terminal facilities. There are four timber docks on the Matan- zas water front of St. Augustine, one being the municipal yacht dock south of the highway bridge, one a fish dock, and two private docks. The principal terminals are the numerous shrimp docks in the San Sebastian River which flows southward through the city into the Matanzas River south of the bridge; these con- sist of timber wharves, with frame and corrugated-iron ware- houses thereon. The present terminals have highway connections and several of the shrimp docks have rail connections. They are considered adequate for existing commerce and yacht traffic, but there are no terminals suitable for an extensive general com- merce. Operations and results during fiscal year. A hydrographic sur- vey of St. Augustine Inlet and adjacent beaches was made during August and September 1950 at a cost of $5,247.39. The costs and expenditures for the year were $5,247.39 for maintenance. Condition at end of fiscal year. The existing project was about 14 percent completed. Between February and August 1941, a straight entrance channel 27 feet deep and 200 feet wide was dredged from the ocean across North Point (Vilano Beach) to deep water in Tolomato River and a granite, native-rock, and creosoted-timber sand-trap groin, 1,580 feet long and extending from the coast line into the ocean, was constructed on the north side of the inlet. The channel rapidly shoaled, and maintenance of adequate depths along that alinement has been impracticable. To stop flanking caused by sea action at the shore end of the structure, the groin was extended 300 feet shoreward at an angle of 450, between September and December 1943. The groin is in fair condition except for the seaward 300 feet which has subsided to about elevation 3.0 feet, mean low water. In September 1950 a depth of 10.4 feet was available in a marked natural channel leading northeasterly from near the seaward end of the groin. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 601 The work remaining to be done to complete the project is that authorized by the River and Harbor Act of May 17, 1950. The costs and expenditures under the existing project have been $392,787.72 for new work and $159,582.29 for maintenance, a total of $552,370.01. In addition, $137,500 were expended from contributed funds for new work. Proposed operations. No work is scheduled for the fiscal years 1952 and 1953.

CANAVERAL HARBOR, FLA. Location. On the east coast of Florida in Canaveral Bight, about 120 miles south of St. Augustine Harbor and 65 miles north of the entrance to Fort Pierce Harbor. (See U. S. Coast and Geo- detic Survey Chart No. 1245.) Existing project. This provides for a turning basin 27 feet deep at mean low water and 1,000 feet wide, with lengths of 900 feet on the north.side and 2,900 feet on the south side, near the easterly shore of Banana River and inclosed by a dike; an en- trance channel 27 feet deep and 300 feet wide extending from the turning basin through the barrier beach, thence flaring to 400 feet wide at the 27-foot contour in Canaveral Bight, protected at its seaward entrance by two jetties to the 12-foot depth contour; a barge canal 8 feet deep at local mean low water and 100 feet wide from the turning basin to the Intracoastal Waterway; and a lock 50 feet wide and 250 feet long to pass the barge canal through the dike inclosing the turning basin. The entrance channel is about 1.8 miles long and the barge canal about 7.5 miles long. The total length of the project is 9.9 miles. Present plans will provide only one jetty, 1,520 feet long, on the south side. 602 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Data relative to the proposed lock Distance to nearest town.................... 10.7 miles via 8-foot barge canal and Intracoastal Waterway. Name of nearest town. ................... .. Cocoa, Fla. Distance from Intracoastal Waterway channel ................................ 7.2 miles. Lock dimensions .......................... 50 by 250 feet. Lift ....................................... Varies with the tide. Depth on miter sills......................... 12 feet below mean low water. Character of foundation...................... Piles in sand. Kind of dam.............................. None. Estimated cost ........................... $1,743,180. The mean range of tide is about 3.5 feet and the maximum range about 6 feet. Onshore winds generally raise the water level from 4 to 6 feet above mean low water. There is no perceptible tidal effect in Indian and Banana Rivers in the general vicinity, but the level of the water is considerably affected by winds, north- erly winds causing a lowering of the waters and southerly winds causing them to rise above normal. Easterly winds cause a rise at the western shores and westerly winds a rise at the eastern shores. The estimate of cost for new work, revised in 1951, is $4,- 624,000 including $850,000 contributed by local interests, but excluding $90,000 received from the sale of dredged material. The estimate also includes $905,000 for construction of jetties, which may not be required. The latest (1951) approved estimate for annual cost of maitenance is $45,500, including $11,000 for oper- ating and care of the lock. The existing project was authorized by the River and Harbor Act approved March 2, 1945 (H. Doc. 367, 77th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. The authorized work is subject to the con- ditions that local interests contribute 50 percent of the estimated first cost of the improvement, but not to exceed $850,000, and furnish assurances satisfactory to the Secretary of War that they will: (1) Furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas required for the improvement and its subsequent maintenance, when and as required; (2) construct, without cost to the United States and in accordance with plans approved by the Secretary of War, ade- quate piers, slips, warehouses, and transit sheds, a precooling plant with a capacity of at least 120,000 standard boxes of citrus fruit per week, a shipside citrus packing plant with a capacity of at least 50,000 standard boxes per week, direct and adequate highway connections between the port terminals and the main- land, and all bridges made necessary by the entire improvement; (3) agree to operate and maintain, free of cost to the United States, all port facilities open to all on equal and reasonable terms; (4) agree to receive and pay for at the rate of 6 cents per cubic yard not less than 1,500,000 cubic yards of material to be dredged by the United States from the barge canal or turning RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 603 basin and deposited upon the right-of-way for the causeway carrying the highway between the port terminals and the main- land; and (5) provide, operate, and maintain, free of cost to the United States, adequate railroad connections between the port and the rail lines on the mainland when the Secretary of War shall require it. An act of the Florida State Legislature in 1939, as amended in 1941, created the Canaveral Port District in Brevard County, and a governing body known as the Canaveral Port Authority with authority to construct and maintain in the district a deep-water harbor with terminal facilities; to borrow not to exceed $5,000,- 000 through the issuance of revenue certificates and bonds; and to levy an ad valorem tax on real and personal property in the port district. Bond issues are to be ratified by the freeholders of the port district in a public election. By letter dated February 22, 1947, the Canaveral Port Au- thority informed the district engineer that the authority had caused plans and specifications for the essential port facilities to be prepared by contract. On January 19, 1949, the Canaveral Port Authority adopted a resolution agreeing to assume full re- sponsibility for the requirements of local cooperation. That resolution was accepted by the Assistant Secretary of the Army on November 21, 1949, as satisfactory assurance of compliance. A bond issue of $1,365,000 for meeting certain of the require- ments of local cooperation was sold September 29, 1949. On No- vember 28, 1949, the port authority contributed the required $850,000 toward the cost of the improvement, and has tendered payment of $90,000 for purchase of 1,500,000 cubic yards of material to be dredged by the United States from the barge canal and turning basin and deposited upon the right-of-way for the causeway carrying the highway between the terminals and the mainland. All rights-of-way and spoil-disposal areas required for original dredging have been furnished. Terminal facilities. None. Operations and results during fiscal year. Dredging, by con- tract, to provide the 8-foot-depth barge canal and the 27-foot- depth turning basin and barrier cut to the 12-foot contour in the ocean, and placing fill on causeway and constructing dike enclosing turning basin, in progress since June 26, 1950, were 77 percent completed at the end of the fiscal year. Contract dredges Ventnor, No. 3, and No. 5 removed 5,827,438 cubic yards of material at a cost of $798,785.09. Leased-plant operations to place fill on the dike and the causeway, begun May 26, 1951, were 63 percent completed at the end of the fiscal year. Dredge Ventnor placed 696,679 cubic yards of fill at a cost of $103,801.97. Engineering studies and preparation of plans and specifications for the lock were completed at a cost of $62,894.65. Engineering studies on other project features cost $1,944.48. The costs for the year were $640,495.41 United States funds, and $326,930.78 contributed funds, a total of $967,426.19 for new work. The expenditures were $453,549.98 United States funds and $326,930.78 contrib- uted funds, a total of $780,480.76. 604 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Condition at end of fiscal year. The existing project was about 25 percent completed. Dredging to provide the 8-foot-depth barge canal and the 27-foot-depth turning basin and barrier cut to the 12-foot contour in the ocean, all to project dimensions, and plac- ing fill on causeway and constructing dike enclosing turning basin have been in progress since June 1950. The barge canal is available for navigation. The work remaining to be done to complete the project is as follows: Completion of dredging in progress; dredging the 27-foot-depth entrance channel seaward of 12-foot contour; construction of the lock; construction of the jetty; and construction of the channel revetment.

FORT PIERCE HARBOR, FLA. Location. On the east coast of Florida, about 218 miles south of the entrance to St. Johns River and about 124 miles north of the entrance to Miami Harbor. (See U. S. Coast and Geodetic Survey Chart No. 582.) Existing project. This provides for the maintenance, enlarge- ment, and deepening of the project developed by private interests, to provide a channel 350 feet wide at the 27-foot contour in the ocean, tapering to 200 feet wide at station 100+00 near the west- erly side of the inlet, thence 200 feet wide across Indian River to station 30+00, and thence flaring on the southerly side to form a turning basin, 1,650 feet long on the northerly side, 750 feet long on the southerly side, and 900 feet wide, the depth to be 25 feet in the basin and in the channel to station 130+00, and thence 27 feet to the 27-foot contour in the ocean; and for maintenance of the jetties at the ocean end of the inlet, and of shore revet- ments within the inlet in prolongation of the jetties. The two parallel rubble-stone jetties with revetment extensions, con- structed by local interest to protect the entrance, are 900 feet apart, the north jetty and revetment being about 3,500 feet long, and the south jetty and revetment about 3,200 feet long. The length of the section included in the project is about 3.5 miles. The mean range of tide is about 2.6 feet at the entrance and 0.7 foot at the terminal, with northeast tides as high as 5 feet above mean low water. The actual cost of new work was $337,183. The latest (1951) approved estimate of annual cost of maintenance is $30,000. The existing project was authorized by the following river and harbor acts: 606 REPORT OF CHIEF OF ENGINEERS, U. S.

These consist of two earth-filled piers retained by steel sheet piling and forming a slip 200 feet wide by 330 to 350 feet long with bulkhead wharf at inner end. These facilities afford a berthing space of about 1,653 feet. The south pier and the bulkhead wharf are muncipally owned, the pier hav- ing a berthing space of 524 feet, with depths of 25.5 to 18 feet. The bulkhead is used for tieup of Government vessels. A ware- house 75 by 280 feet is on the municipal pier, and a precooling plant 102 by 365 feet occupies the north pier, just landward of which is another warehouse, 150 by 100 feet. A fruit-packing house 170 by 225 feet is at the west end of the slip. The north pier is served by railway and both piers by highway connections. North of the turning basin there is a bulkhead wharf with a depth of 15 to 12 feet and with tank storage in the rear for petroleum products. The facilities are considered adequate for existing commerce. (See Port and Terminal Facilities Report, 1941, Corps of Engineers.) Operations and results during fiscal year. Periodic condition surveys, inspections, and contingencies cost $2,342.47. Prelimi- nary plans and specifications for repair of revetment cost $168.17. The cost for the year was $2,510.64. The expenditures were $1,310.64. Condition at end of fiscal year. The existing project was com- pleted in February 1938. Dredging was begun in July 1936 and completed in February 1938. Restoration of the jetties originally constructed by local interests was begun in October 1933 and completed in August 1934 as a maintenance feature. Both jetties are in good condition. The revetments are in fair condition; both are ragged, with nearly vertical faces along the water side re- sulting from loss of numerous stones into the water. The west- erly 500 feet of the south revetment is in very poor condition; of that section, the westerly 200 feet has disappeared and needs replacing to prevent further shore erosion. Stones should also be replaced in the adjacent 300 feet of that section.

PALM BEACH HARBOR, FLA. Location. On the east coast of Florida about 71 miles north of the entrance to Miami Harbor. It is the entrance channel to the Port of Palm Beach. (See U. S. Coast and Geodetic Survey Chart No. 1248.) 608 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Existing project. This provides for maintaining, deepening, and enlarging the improvements constructed by local interests to provide a channel 25 feet deep at mean low water (plus 2 feet of overdepth from the ocean to station 65+00 and 1 foot of over- depth thence to and in the turning basin), and 300 feet wide from deep water in the ocean to station 69+00, thence reducing to a width of 200 feet at station 65+00, near the westerly side of the inlet, thence 200 feet wide across Lake Worth to station 31+54 (with widening at the junction with the turning basin), thence flaring to form a turning basin of the same depth on the westerly side of the lake, of irregular shape, varying in length from about 1,375 feet on the north side to 900 feet on the south side, and with a minimum width of 1,250 feet over the westerly 900 feet of its length; for removing the obstructive point on the south side of the inlet; for reveting the banks of the inlet; and for restoring the existing jetties. The jetties constructed at the entrance by local interests consist of two parallel rubblestone structures 800 feet apart, the north jetty and revetment being about 1,800 feet long and the south jetty, 1,700 feet long. The length of section under improvement is about 1.3 miles. The mean range of tide is 2.8 feet at the inlet and 1.8 feet at the Port of Palm Beach terminals. The extreme range is about 4.5 feet at the inlet and 3 feet at the terminals. The estimate of cost for new work, revised in 1951, is $1,688,- 740. The Secretary of the Army is authorized to reimburse local interests, not to exceed $305,000, for such work as they may have done in extending the turning basin southward subsequent to July 1, 1949. The latest (1951) approved estimate of annual cost of maintenance is $31,000.

Local cooperation. The conditions imposed by the River and Harbor Act of August 30, 1935 (H. Doec. 185, 73d Cong., 2d sess.) have been complied with except for furnishing perpetual ease- ments for access to the easement areas adjacent to the channel RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 609 through the inlet. The River and Harbor Act of March 2, 1945, among other conditions, imposed the requirement that local in- terests give assurances satisfactory to the Secretary of War that they will provide additional berthing space and terminal facilities when needed to accommodate any increase in the commerce of the port, and furnish suitable spoil-disposal areas for subsequent maintenance of the work as and when required. A resolution adopted August 1, 1945, by the Port of Palm Beach District agreeing to comply with all conditions imposed by the act was accepted by the Secretary of War on October 3, 1945, as satis- factory assurance of compliance. All other requirements imposed by the act of 1945 have been fully complied with. The River and Harbor Act approved May 17, 1950 (H. Doc. 704, 80th Cong., 2d sess.), imposed the condition that local inter- ests furnish assurances satisfactory to the Secretary of the Army that they will furnish, free of" cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas for the work and subsequent maintenance, when and as required; and will pro- vide and maintain, in accordance with plans approved by the Chief of Engineers, a new slip with highway and rail connections and other appurtenances, open to all on equal and reasonable terms. In partial compliance local interests have partially com- pleted slip No. 2 as described in the paragraph '"Terminal facili- ties." While not required under the conditions of local cooperation, the Port of Palm Beach District, during 1944, dredged the area south and southeast of the then-existing project turning basin to a depth of 12 to 15 feet or to rock. During 1946 the port district widened the turning basin generally 200 feet to the south and east to a depth of 22 feet. Terminal facilities. These consist of slip No. 1, 690 feet long, 210 feet wide, and 26 feet deep, with a wharf on either side and a bulkhead at the inner end, two additional shore wharves, and slip No. 2, about 200 feet south of slip No. 1, 500 feet long, 250 feet wide, 32 feet deep, and bulkheaded for about 450 feet on the northerly side at the easterly end; also, the face of the pier formed between the two slips has been bulkheaded. Slip No. 2 will eventu- ally be extended to 800 feet long, with the same width and depth as stated. Adjacent to the bulkhead an area 100 by 350 feet has been paved with limerock for open storage of bulk cargoes. These facilities afford a total berthing space of about 2,742 feet, with depths ranging from 32 to 17 feet. All wharves belong to the Port of Palm Beach District. A steel-and-concrete warehouse, 70 by 620 feet, a wooden frame building, 70 by 140 feet, and an office building have been constructed on the north side of the slip; the former precooling plant, 36 by 124 feet, north of the warehouse has been remodeled for use as a warehouse for express traffic. Two nearby storage depots for petroleum products and one for tank storage of imported fountain syrup are connected with the terminals by pipe lines. Equipment for transfer of railroad freight cars to and from car ferries has been installed and is ex- tensively used. Rail and highway connections, water supply; and 610 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 other facilities have been provided to the warehouses and shipside of the slips. The facilities are considered inadequate for existing commerce, but will be adequate upon completion of slip No. 2 and appurtenant features. (See Port and Terminal Facilities Report, 1941, Corps of Engineers.) Operations and results during fiscal year. New work: Dredg- ing, by local interests, to extend the turning basin 550 feet southward over a 900-foot width, with a flare to the east, in progress at the beginning of the fiscal year, was completed July 13, 1950. Subsequently, local interests made application for reim- bursement under provisions of the River and Harbor Act of May 17, 1950. Maintenance: Repairs, by contract, to 2,329 linear feet of the south jetty, 46 percent completed at the beginning of the fiscal year, was completed September 8, 1950. A total of 14,559.5 tons of granite, consisting of boulders weighing from 1/2 to 15 or more tons, was placed at a cost of $121,817.58. The United States hopper dredge Hyde removed 122,928 cubic yards of material, bin measurement, from the entrance channel from January 9 to 23, 1951, at a cost of $34,342.06. Periodic condition surveys and inspections cost $4,228.08. The costs for the year were $160,387.72, all for maintenance. The expenditures were $243,880.40. Condition at end of fiscal year. The existing project was phy- sically 100 percent completed. Between 1918 and 1920, local interests dredged a channel 15 to 18 feet deep, 300 feet wide through the inlet and 150 feet wide across Lake Worth, with a turning basin on the western shore of the lake, and constructed two stone jetties and revetment extensions to protect the channel at the entrance. The United States deepened the entrance chan- nel and turning basin to 20 feet and widened the channel across Lake Worth to 200 feet between February 1935 and December 1937, and restored the stone jetties and revetments and removed the obstructive land point at the south side of the inlet between October 1936 and June 1938. The entrance channel and turning basin were further deepened to 25 feet, plus overdepth, between March 1947 and November 1948. During July 1949, local inter- ests began dredging, on a reimbursable basis, to extend the turn- ing basin 550 feet southward, with a flare to the east. The work was later discontinued, but was resumed by them during June 1950 and completed in July 1950. Local interests, however, had not been reimbursed for the work. As reconstructed, the north jetty and revetment are 950 and 1,500 feet long, respectively; 850 feet of the shoreward end of the jetty has been capped with concrete, and voids in the granite enrockment at the seaward end of the structure have been filled with asphaltic concrete which is now in poor condition. The south jetty and revetment are 1,890 and 420 feet long, respec- tively; 1,790 feet of the shoreward end of the jetty has been capped with concrete, but no asphaltic concrete was placed in the voids of the granite enrockment at the seaward end. Both jetties were in good condition except for hurricane and storm damages RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 611 to the south jetty as follows: The outer 500 feet of concrete cap has settled generally from 1 to 6 inches due to displacement and scattering of outlying granite base rocks formerly protecting the concrete cap; two 40-foot sections of the concrete cap were badly cracked longitudinally-one 400 feet from the east end of the concrete cap, the other near the land end; and the 100-foot section of nonbonded rubble granite at the seaward end has about disappeared. Repairs by contract were performed on the south jetty and revetment, and new granite base rocks were placed on both sides of the concrete cap for its full length. The work was completed September 8, 1950. At the end of the fiscal year controlling depths were about as follows: Sea buoy to seaward end of jetties, 29.5 feet in mid- channel for half project width with a limiting depth of 28 feet in the right outside quarter and 29.2 feet in the left outside quarter; the channel between the jetties and through the land cut and thence across Lake Worth to the turning basin, 24.8 feet in mid- channel for half project width, with limiting depths of 24.8 feet in the right outside quarter and 22.7 feet in the left outside quarter; and in the turning basin, 27 feet.

PORT EVERGLADES HARBOR, FLA. Location. On the east coast of Florida, about 23 miles north of Miami and about 48 miles south of Palm Beach Harbor, Fla. The site of the harbor is in Lake Mabel. (See U. S. Coast and Geodetic Survey Chart No. 546.) Existing project. This authorizes the maintenance, enlarge- ment, and deepening of the improvements constructed by local interests to provide a channel 500 feet wide at its seaward end, converging to 400 feet at the jetty entrance, thence converging to 300 feet at a point 1,000 feet within the jetty entrance, and thence 300 feet wide, and flaring at the inner end to a turning basin 1,200 feet long and 2,250 feet wide over the major portion of its length, all to a depth of 35 feet at mean low water; and the maintenance of two converging rubblestone jetties con- structed at the entrance to protect the channel, and of two paral- lel steel-sheet-piling bulkheads 800 feet apart to protect the land points of the inlet from erosion. The entrance channel is about 7,300 feet long. The jetties are 700 feet apart at the outer ends and 1,200 feet apart at the shore ends. The north jetty is angular and about 1,450 feet long; the south jetty is straight and about 1,250 feet long. Both jetties were built to 6 feet above mean low water with top widths of 6 feet at the shore ends and 12 feet at the sea ends, and with side slopes of 1 on 11/2. The mean range of tide is 2.5 feet at the entrance and 2.3 feet at the terminals; the extreme range is about 4.5 feet, with storm tides of about 6.5 feet. The actual cost of new work was $2,200,538.11. The latest (1951) approved estimate of annual cost of maintenance is $42,500. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 613 Acts Work authorized Documents July 3, 1930 Maintenance of the harbor as constructed by local H.

The River and Harbor Acts approved Au- gust 30, 1935, and June 20, 1938, imposed the condition, among others, that local interests provide suitable areas for the disposal of dredged material for maintenance. In addition, the latter act included the requirement that local interests agree to provide the slips, piers, and other terminal facilities necessary for the full utilization of the improvement. A resolution adopted January 26, 1939, by the Broward County Port Authority, agreeing to provide suitable and sufficient slips, piers, and other terminal facilities necessary for the full utilization of the improvement, was accepted by the Chief of Engineers February 20, 1939, as satisfactory assurance of compliance with that part of the re- quired local cooperation. In partial compliance with the condi- tions, the port authority has provided slip No. 2 described below under "Terminal facilities." All other requirements affecting orig- inal construction as imposed by the two acts have been fully complied with. Sufficient temporary spoil-disposal areas have been furnished for maintenance as and when required. The River and Harbor Act approved July 24, 1946, imposed the conditions that responsible local interests agree to (a) provide, free of cost to the United States, all necessary lands and rights- of-way and suitable spoil-disposal areas, diked as necessary, for new work and for subsequent maintenance, when and as required; (b) promptly dredge and bulkhead slip No. 3 and the berth at the east end of pier No. 3 on completion of the improvement in the southern part of the turning basin by the Government; and (c) hold and save the United States free from damages resulting from the work. A resolution adopted by the Broward County Port Authority on October 23, 1947, assuming responsibility for com- pliance with the above provisions of local cooperation, was accepted by the Chief of Engineers on October 30, 1947, as satis- factory assurance of compliance. All new-work spoil areas and easements in perpetuity for required rights-of-way have been furnished. Slip No. 3 has been dredged to the dimensions and depth stated below under "Terminal facilities." While not required under the conditions of local cooperation, the Broward County Port Authority, in 1946, partially completed dredging an area of about 125,000 square feet on the westerly side, and within the project limits, of the 500-foot extension to the southerly side of the turning basin. Terminal facilities. These consist of seven commercial wharf facilities at Port Everglades owned and operated by Broward 614 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 County Port Authority, all open to the public. They are on the three slips that have been dredged off the turning basin. Slips No. 1 and 2 are 35 feet deep and 300 feet wide, and are respec- tively 1,200 feet and 700 feet long, with steel-sheet-pile bulk- heads on both sides of each slip and at the end of slip No. 1. Slip No. 2 was so constructed as to permit future extension to a length of 1,200 feet. Slip No. 3, 1,200 feet long and 300 feet wide, is 35 feet deep but is inactive at present due to pending bulkhead con- struction. A modern steel transit shed has been constructed on pier No. 2, and a privately operated precooling plant on pier No. 1. All wharves have railway and highway connections and pipe- line connections to one or more of the 13 storage depots for petroleum products, one of which is also for blackstrap molasses. The facilities are considered inadequate for the existing com- merce. (See Port Series No. 16, revised 1947, Corps of Engi- neers.) Operations and results during fiscal year. Periodic surveys and inspections cost $148.18 for maintenance. The cost and ex- penditures for the year were $148.18 for maintenance. Condition at end of fiscal year. The existing project was com- pleted in January 1949. Local interests dredged an entrance chan- nel 210 feet wide, 35 feet deep, and about 6,900 feet long, from the ocean to a partially,completed turning basin 1,200 feet square and constructed two converging angular-stone jetties to protect the entrance channel and two steel-sheet-pile bulkheads to pro- tect the land points. The United States enlarged the entrance channel to project dimensions, completed the 1,200-foot-square turning basin to a depth of 35 feet, widened it to a maximum width of 2,250 feet, and enlarged the flare of the south side of the entrance channel at the basin between December 1936 and Jan- uary 1949, and reconstructed the jetties as a maintenance feature between May and September 1932. The seaward end of the south jetty was straightened in connection with jetty repairs between June and August 1940. Both jetties are in good condition. The steel-sheet-pile bulkhead at the inner end of the south jetty is in poor condition, and the similar bulkhead on the north side of the land cut is in fair condition. The sheet piling, except for a short section at the seaward end, was cut off at the low-tide line during construction for concrete capping, which was never placed. The tie-back piles and deadman timbers have been virtually destroyed above earth line by marine borers. When last surveyed, the controlling depths were as follows: Entrance channel from the ocean to the turning basin, 35 feet in the middle half of the channel and in the left outside quarter in April 1948; and in the turning basin, 35.3 feet, except in the left outside quarter where the limiting depth is 34.5 feet, April 1948 and January 1949. The costs and expenditures under the existing project have been $2,200,538.11 for new work and $353,702.33 for mainte- nance, a total of $2,554,240.44. Proposed operations. No work is scheduled during the fiscal year 1952. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 615 The sum of $64,300 can be profitably expended during the fiscal year 1953 for maintenance dredging to a depth of 35 feet with a United States hopper dredge to remove critical shoaling throughout the project, and for a condition survey preliminary to dredging.

MIAMI HARBOR, FLA. Location. Miami is near the northerly end of Biscayne Bay, about 335 miles southeasterly from the entrance to Jacksonville Harbor. Miami River has its source in the Everglades and flows southeasterly to enter Biscayne Bay at Miami. (See U. S. Coast and Geodetic Survey Charts Nos. 547 and 1248.) Existing project. This provides for the following: (a) A chan- nel 30 feet deep and 500 feet wide from the 30-foot contour in the ocean to near the outer end of the north jetty, thence 300 feet wide through the entrance and across Biscayne Bay to and in- cluding a turning basin 1,400 feet long and 1,350 feet wide on the westerly side of Biscayne Bay in front of the muncipal terminals at Miami; (b) two parallel rubblestone jetties at the entrance, 1,000 feet apart and 3,000 and 2,750 feet long, respectively; (c) an approach channel 300 feet wide and a turning basin of irregu- lar shape about 2,000 square feet, both 30 feet deep, at Virginia Key, and dredging 12,060,000 cubic yards of material from the bay bottom in addition to that to be dredged from the approach channel and turning basin to provide fill for the island, with such modifications as in the discretion of the Secretary of the Army and the Chief of Engineers may be advisable; (d) a channel 15 feet deep and 200 feet wide from the mouth of Miami River to the turning basin at the municipal terminals; (e) a channel 8 feet deep and 200 feet wide from the mouth of Miami River to the Intracoastal Waterway and thence 100 feet wide to Govern- ment Cut; (f) a channel at the mouth of Miami River, 15 feet deep at mean low water, 250 feet wide at the outer end and taper- ing to 170 feet wide at Brickell Point in a distance of about 1,400 feet; thence a channel in Miami River, 15 feet deep under flood conditions, 150 feet wide for 3 miles, thence 125 feet wide for 1.1 miles, and thence 90 feet wide for 1.4 miles; (g) a channel 12 feet deep and 100 feet wide from Miami River to a harbor of refuge in Palmer Lake, the location of the harbor of refuge and channel leading thereto being subject to modification at the 616 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 discretion of the Chief of Engineers; .(h) an approach channel 6 feet deep and 700 feet wide to the harbor line at the seaplane base at Dinner Key, with an enlargement at the inner end and with a channel 8 feet deep and 50 feet wide along the easterly edge of the widening. The plane of reference is mean low water, except for the 15-foot channel in Miami River where depths are based on flood condi- tions. The total length of the waterway under improvement is about 17.7 miles, including about 6 miles of entrance channel from the ocean to and including the turning basin at the munici- pal terminals, 1.6 miles of approach channel to Virginia Key, 5.8 miles in Miami River, 3.5 miles in the connecting channels leading therefrom into the bay, and 0.8 mile at Dinner Key Airport. The mean tidal variation is 2.5 feet at the entrance and 2 feet in the bay. The extreme variation is about 4.5 feet at the entrance and 3 feet in Biscayne Bay. Strong easterly winds raise the water level about 1.5 feet at the entrance and 1 foot in the bay. Strong westerly winds lower the water level about 1 foot at the entrance and about 0.5 foot in the bay. The estimate of cost for new work, approved in 1951, is $14,- 275,000, including $23,000 to be contributed by local interests. The latest (1951) approved estimate of annual cost of main- tenance is $75,000.

RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 617 Local cooperation. All work authorized by the River and Har- bor Act approved March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, and rights-of-way and suitable spoil-disposal areas for the initial work and subsequent maintenance, as and when re- quired, and hold and save the United States free from claims for damages resulting from the improvement. Additional require- ments imposed by the act of March 2, 1945, are as follows: (a) The Virginia Key improvement is subject to the conditions that local interests give assurances satisfactory to the Secretary of War that they will provide auxiliary channels and suitable air- port and harbor terminal facilities at Virginia Key generally in accordance with the plans submitted by the district engineer and subject to such modifications as the Chief of Engineers may re- quire, and provide such operating facilities as the United States may require; (b) the provision of a channel from Miami River to the harbor of refuge is subject to the conditions that local interests contribute one-third of the initial cost of the channel, furnished assurances satisfactory to the Secretary of War that they will provide and maintain suitable depths in the harbor of refuge and construct and maintain adequate mooring facilities therein, and agree that, at any time upon the approach of a hurrican or severe storm, and specifically upon the request of the district engineer or his authorized representative, the refuge basin will be open to all without charge until storm danger is past. On March 21, 1945, local interests were informed as to the requirements of local cooperation imposed in connection with the Virginia Key improvement. No assurance of compliance with those requirements has been received. On September 5, 1945, the Commission of the City of Miami, Fla., adopted a resolution agree- ing to assume responsibility for compliance with the local coop- eration requirements imposed in House Document No. 91, Seventy-ninth Congress, first session, except those pertaining to the channel from Miami River to the harbor of refuge in Palmer Lake. On May 9, 1946, that resolution was accepted by the Secre- tary of War as satisfactory assurance of partial compliance. All prior requirements have been fully complied with. Terminal facilities. These consist of 42 piers and wharves, of which 5 are on the east side of Biscayne Bay at Miami Beach, 1 is on Fisher Island, 5 are along the south side of MacArthur Causeway, 7 are on the west side of the bay at Miami, and 18 are on Miami River. Seven of the facilities are open to the public for handling general cargo. Four of these, including three municipal piers on the west side of the bay and a privately owned pier near the east end of MacArthur Causeway, can accommodate deep- draft vessels. The other three general cargo facilities are suitable for small vessels, and include the Florida East Coast Railway wharf south of the municipal piers, and two privately owned wharves on Miami River. All of the general cargo wharves have highway and railway connections except the causeway terminal, which has highway connections only. A municipal yacht anchor- age and basin and a municipal wharf are open to the public 618 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 for recreational craft. Of the remaining piers and wharves, 7 in the bay and 2 on Miami River are used for handling petroleum products, 17 are used in connection with ship-repair activities, 6 are used for mooring vessels or handling private freight, and 2 are idle. Three of these facilities have railway connections, and all have highway connections except a petroleum wharf on Fisher Island. In addition, numerous landing facilities in and around Miami, especially on Miami River, are designed for and used exclusively by recreational craft. The facilities are considered in- adequate for the existing commerce. (See Port Series No. 16, revised 1947, Corps of Engineers.) Operations and results during fiscal year. New work: Engi- neering studies cost adjustment reduced the cost $38.52. Maintenance: Periodic surveys and inspections cost $679.34. Maintenance of reservation and bank revetment on north side of entrance channel cost $12,167.81. The cost for the year was -$38.52 for new work and $12,847.15 for maintenance, a total of $12,808.63. The expenditures were $12,578.24. Condition at end of fiscal year. The existing project was about 51 percent completed. The main 30-foot entrance channel from the ocean to and including the turning basin was dredged progres- sively between August 1904 and March 1939. A land cut 20 feet deep and 300 feet wide was dredged across the peninsula to Bis- cayne Bay between August 1904 and October 1923; a channel 25 feet deep from the ocean to and including the former municipal turning basin at Miami (200 feet wide across the bay, and follow- ing the alinement of the former municipal channel) was dredged between July 1926 and December 1933, and was deepened to 30 feet, including widening the channel across the bay to 300 feet and enlarging the turning basin, between April 1934 and March 1939. A channel 15 feet deep at mean low water and 150 feet wide along the land point at the mouth of Miami River for 1,400 feet and thence northerly along the bay front for about 1,200 feet, and a channel in Miami River for 5.5 miles above its mouth, 15 feet deep under flood conditions and of project widths, were dredged between March 1932 and August 1933. The channels at the Dinner Key seaplane base were dredged between February and August 1933. The two stone jetties at the entrance were con- structed to the 18-foot contour between March 1904 and October 1908, extended 405 feet each in 1922, and extended to their present lengths between September 1926 and March 1929. The north jetty and revetment is 4,688 feet long and the south jetty and revetment, 3,850 feet long. The south jetty, both revetments, and that part of the north jetty landward of the low-tide shore line in the ocean are in good condition. Seaward of the low-tide shore line the north jetty is in fair condition; that section was damaged during the hurricane of November 1935. Numerous pieces of granite were dislodged from the upper part of the jetty and now rest on the ocean bed along the jetty. At several points in the jetty, the crest has been lowered to the plane of mean high tide. No sand encroachment RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 619 toward the channel has taken place through the lowered sections.

OKEECHOBEE WATERWAY, FLA. Location. Caloosahatchee River has its source in Lake Okee- chobee and flows generally southwesterly, emptying into the Gulf of Mexico through San Carlos Bay, about 30 miles south of the entrance to Charlotte Harbor. (See U. S. Coast and Geodetic Survey Charts Nos. 473, 1247, 1255, and 1289.) Lake Okeechobee is a large, fresh-water lake in south-central Florida. (See U. S. Coast and Geodetic Survey Chart No. 1289.) St. Lucie Canal was constructed by the Everglades Drainage District as a control canal for Lake Okeechobee. It begins at about the middle of the east shore of Lake Okeechobee and empties into the south branch of the St. Lucie River at St. Lucie lock. The length of the canal is 23.9 miles. (See U. S. Coast and Geodetic Survey Chart No. 1289.) St. Lucie River, South Fork, flows north from the entrance of the St. Lucie Canal about 7.4 miles to Stuart, where it joins RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 621 North Fork to form the St. Lucie River, thence east, southeast, and east about 7.7 miles, emptying into the Indian River opposite St. Lucie Inlet. (See U. S. Coast and Geodetic Survey Charts Nos. 1247 and 1289.) Taylor Creek is formed by several small streams in central Okeechobee County, and flows generally southeasterly, emptying into Lake Okeechobee at its most northerly extremity. (See U. S. Coast and Geodetic Survey Chart No. 1289.) (For description of above waterways see p. 705, Annual Report for 1932.) Previous projects. Original projects for Caloosahatchee River below and above Fort Myers were adopted by River and Harbor Acts of August 2, 1882', and August 11, 1888, respectively. The next project was adopted by the River and Harbor Act approved June 25, 1910, which authorized the present project depths in Caloosahatchee River from Fort Myers to the Gulf of Mexico, with a turning basin at Fort Myers, and was modified by the River and Harbor Acts approved July 3, 1930, and August 30, 1935, under the title "Caloosahatchee River and Lake Okeechobee drain- age areas, Florida," to provide, among other things, for a navig- able channel across the State and for control of Lake Okeechobee, including construction of locks at Ortona and Moore Haven. For further details see page 1828, Annual Report for 1915; page 707, Annual Report for 1932; pages 878-888, Annual Report for 1948; and pages 785 and 831, Annual Report for 1949. Existing project. This provides for: (a) Replacing old locks Nos. 1 and 2, St. Lucie Canal, by a single new lock with a usable width of 50 feet, a usable length of 250 feet, a depth, of not less than 8 feet over the sills, and a new weir structure; (b) a channel 8 feet deep from Fort Myers to the Intracoastal Water- way near Stuart, with widths of 90 feet from Fort Myers to Moore Haven, thence 80 feet along the southerly shore of the lake to the hurricane gate at Clewiston, thence 100 feet across Lake Okeechobee to and in the St. Lucie Canal to St. Lucie lock, and thence 80 feet to the Intracoastal Waterway; (c) a channel 8 feet deep and 100 feet wide from the project turning basin to the ex- isting municipal yacht basin at Fort Myers; (d) a basin 8 feet deep, 200 feet wide, and 400 feet long at Stuart; and (e) under maintenance, the operating and care of St. Lucie lock. The project also includes maintenance of features completed under previous projects as follows: (a) A channel 12 feet deep and 200 feet wide from the Gulf of Mexico to Punta Rasa, about 3.8 miles, thence 10 feet deep and 100 feet wide to Fort Myers (Edison Memorial Bridge), about 16.3 miles, with a turning basin at that point; (b) a channel in Taylor Creek 6 feet deep when the lake is at elevation 12.56 mean sea level (elevation 14 feet Lake Okeechobee datum), and 60 feet wide from the town of Okeecho- bee into the lake, 4 miles; (c) a navigation channel 6 feet deep and 80 feet wide following in general the south shore of Lake Okeechobee from Clewiston to the St. Lucie Canal, 36.7 miles; and (d) the operating and care of the Moore Haven and Ortona locks. 622 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The total length of the waterway from the Gulf of Mexico to the Intracoastal Waterway is about 154.6 miles via the channel across Lake Okeechobee, or about 165.3 miles via the channel along the south shore of the lake. On July 1, 1947, mean sea level datum, which is 1.44 feet above the Lake Okeechobee datum previously used between the St. Lucie and Ortona locks, was adopted for use throughout the project. Project depths are based on minimum water elevations referred to mean sea level, as follows: Feet St. Lucie River, Indian River (Intracoastal Waterway) to St. Lucie lock .................................................... -0.49 St. Lucie Canal and Lake Okeechobee, St. Lucie lock to Moore Haven lock ....................................................... 12.56 Caloosahatchee Canal, Moore Haven lock to Ortona lock.......... 10.06 Caloosahatchee River, Ortona lock to the Gulf of Mexico......... -0.88 The following table shows the principal features of the locks and dams (spillways are maintained under the flood-control proj- ect for central and southern Florida) : St. Lucie Canal Caloosahatchee Canal St. Lucie lock 1 Moore Haven lock Ortona lock and dam and dam Distance from Lake Okeechobee. 23.9 miles............. 0 ....-----------.........--- 15.5 miles. -------- Nearest town (Florida)...........

Appropriation Repeal Act of June 26, 1934. Local cooperation. All work authorized by the River and Har- bor Act approved March 2, 1945, is subject to the conditions that local interests furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas when and as required for the initial work and for subsequent maintenance, and hold and save the United States free from all claims for damages resulting from the improvement. The provision of a channel from the project turning basin to the municipal yacht basin at Fort Myers and of a basin at Stuart is subject to the additional requirements that local interests provide, maintain, and operate adequate mooring and servicing facilities open to all on equal and reasonable terms, make additional improvements to protect the Fort Myers yacht basin from wave action, and inclose the Stuart basin in accordance with plans to be approved by the Chief of Engineers. A resolution adopted November 10, 1945, by the Board of Com- missioners of the Okeechobee Flood Control District (an agency created by the State of Florida to comply with the requirements imposed by the River and Harbor Act of July 3, 1930) agreeing to comply with the requirements of local cooperation imposed in ref- erence to deepening the waterway to 8 feet between Fort Myers and the Intracoastal Waterway (H. Doc. 696, 76th Cong., 3d sess.) was accepted by the Chief of Engineers on February 18, 1946, as satisfactory assurance of compliance. All lands and spoil-disposal areas required for the initial work of deepening the waterway to 8 feet have been furnished. On July 28, 1949, the Okeechobee Flood Control District adopted two resolutions transferring the agreements, commitments, and assets of the Okeechobee Flood Control District to the Central and Southern Florida Flood Control District. On July 14, 1949, the Central and Southern Florida Flood Control District adopted a resolution ac- cepting the assets of the Okeechobee Flood Control District and assuming its agreements and commitments as of midnight July 624 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 31, 1949. On November 25, 1949, the Chief of Engineers author- ized the Jacksonville district engineer to notify both districts that the subject transfer was satisfactory to the Corps of Engineers. A resolution adopted November 17, 1949, by the City Council of Fort Myers, agreeing to comply fully with all the requirements in connection with the side channel at Fort Myers as set forth in House Document 736, Seventy-ninth Congress, second session, was accepted by the Chief of Engineers on January 23, 1950, as satisfactory assurance of compliance. On March 14, 1945, the chamber of commerce and city of Stuart, Florida., were requested to furnish a similar resolution in respect to the basin at Stuart, but no action has been taken. All prior requirements have been fully complied with. Terminal facilities. In the vicinity of Fort Myers on the Caloo- sahatchee River, these consist of three freight piers, one railroad terminal pier, one municipal recreation pier, four privately owned piers, and a municipal yacht basin. A mooring basin has been provided at La Belle. There are numerous small wooden-pile land- ings along the upper Caloosahatchee River, along the lake shore, on St. Lucie Canal, and on St. Lucie River, including one railroad terminal pier, a municipal pier, and a pier for handling petroleum products at Stuart. A marginal wharf 30 feet long and other limited facilities with highway and railway connections are avail- able on Taylor Creek at the town of Okeechobee. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: Dredg- ing to deepen the Caloosahatchee River and Canal to 8 feet from Ortona lock to Fort Myers and to provide a channel 8 feet deep and 100 feet wide to connect the project turning basin with the municipal yacht basin at Fort Myers, 64 percent completed at the beginning of the fiscal year, was completed August 9, 1950.

Ortona lock was dewatered by hired labor from May 14 to June 14, 1951, to permit sandblasting and painting by contract. The under-water surfaces and portions of the surface above were sandblasted, conditoned with WP-1, and given four applications of Vinyl Resin base paint; and all remaining metal surfaces of the lock were spot-chipped, wire- brushed, and given coats of red lead and aluminum paint as re- quired, between May 17 and June 29, 1951. Lubrication systems and rubber seals were replaced as necessary by hired labor. The costs for the year were $53,887.94 for operations, $27,644 for ordinary repairs, and $3,321.22 for improvement and reconstruc- tion, a total of $84,853.16, including $5,584.45 for the work done by contract. The costs of all work during the fiscal year were $25,682.78 for new work, $87,493.82 for maintenance, and $84,853.16 for operating and care, a total of $198,029.76. The expenditures were $238,084.40. Condition at end of fiscal year. The existing project was about 99 percent completed. Construction of St. Lucie lock and spill- way at the lower end of St. Lucie Canal near Stuart was begun in August 1939 and completed in June 1943 except for installation of Tainter gates in the spillway, which was completed in March 1950. An auxiliary lock gate has been installed in the upstream end of old lock No. 2. That lock, constructed by the Everglades Drainage District, is adjacent to and supplements the new lock. Dredging to deepen the waterway to 8 feet between Fort Myers and the Intracoastal Waterway near Stuart, with over-depth in St. Lucie Canal, begun in June 1948, was completed, together with dredging to provide a channel 8 feet deep and 100 feet wide to connect the project turning basin with the municipal yacht basin, August 9, 1950. Features completed under the previous project and maintained under the existing project are as follows: A channel 12 feet deep and 200 feet wide from the Gulf of Mexico to Punta Rasa, and thence 10 feet deep and 100 feet wide to Fort Myers, with a turning basin at that locality, January 1911 to January 1913; the improved Caloosahatchee Canal and River channel from Moore Haven to Fort Myers, 56.5 miles, providing a floodway and navi- gation channel at least 7 feet deep and 90 feet wide, and with a discharge outlet capacity of 2,500 cubic feet per second from Lake Okeechobee, February 1931 to June 1937; a channel 8 feet deep and 80 feet wide in St. Lucie River between Palm City bridge and St. Lucie lock, about 2.8 miles, September to December 1931; a channel 6 feet deep and. 60 feet wide in Taylor Creek from the town of Okeechobee to Lake Okeechobee, about 4 miles, July 1936 to March 1938; 58.3 miles of navigation channel from Moore Haven lock to St. Lucie Canal, generally 8 feet or more deep with a minimum width of 80 feet, following in general the south shore of the lake, January 1932 to March 1936; a lock at Ortona, and 626 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 a combined lock and hurricane gate at Moore Haven, November 1934 to June 1943. For work constructed under previous projects and now main- tained under the flood control project for central and southern Florida, see paragraph "existing project," Central and Southern Florida. For information relative to the St. Lucie, Moore Haven, and Ortona locks, see table in the paragraph "Existing project." Depths in excess of 8 feet exist in the St. Lucie Canal and across Lake Okeechobee by following in general the south shore of the lake. St. Lucie Canal was constructed 8 feet deep and 150 to 165 feet wide by the Everglades Drainage District between 1916 and 1928 as a control canal for Lake Okeechobee. The controlling depths when last surveyed were as follows: Gulf of Mexico to Punta Rasa, 12 feet for a width of 200 feet in August 1950; Punta Rasa to Fort Myers, 10 feet for a width of 100 feet in August 1950; Fort Myers to Ortona lock, 8 feet for a width of 90 feet in August 1950; Ortona lock to Lake Okeechobee at Moore Haven, 8 feet for a width of 90 feet in April 1949; Lake Okeechobee from Moore Haven to St. Lucie Canal via south- shore channel, 9 feet for a width of 50 feet in April 1949; via Liberty Point floodway channel and open lake, 5 feet for a width of 60 feet in April 1950; via Clewiston approach channel, 8 feet for a width of 100 feet in March 1950; Lake Okeechobee to St. Lucie lock, 9 feet for a width of 80 feet in November 1949; St. Lucie River from the lock to Intracoastal Waterway near Stuart, 8 feet for a width of 80 feet in March 1950; and Taylor Creek from the town of Okeechobee to Lake Okeechobee, 6 feet for a width of 60 feet in February 1949. The present controlling chan- nel width of 80 feet is reduced to 50 feet at locks and at 19 localities by bridges, with a limiting horizontal clearance of 50 feet at the highway bridge near La Belle. The work remaining to be done to complete the project is to dredge a basin 8 feet deep, 200 feet wide, and 400 feet long at Stuart. The costs under the existing project have been $3,803,447.47 for new work, $292,921.55 for maintenance, and $563,501.83 for operating and care, a total of $4,659,870.85. The expenditures have been $4,589,932.70. Proposed operations.

INTRACOASTAL WATERWAY, CALOOSAHATCHEE RIVER TO ANCLOTE RIVER, FLA. Location. The waterway extends from the mouth of the Caloo- sahatchee River at Punta Rasa, Fla., to the mouth of Anclote River, Fla., following in general an almost continuous series of protected inside waterways along the Gulf coast of Florida. (See U. S. Coast and Geodetic Survey Charts Nos. 1255-1257.) Previous projects. Adopted by the following river and harbor acts: For the improvement of the inside passage from Punta Rasa to Charlotte Harbor (Pine' Island Sound), act of June 13, 1902; for Caseys Pass (Venice Inlet), act of August 30, 1935; for Sara- sota Bay (including Little Sarasota Bay), acts of September 19, 1890, June 3, 1896, March 2, 1907, March 2, 1919, and August 26, 1937; and for Channel from Clearwater Harbor through Boca Ciega Bay to Tampa Bay, acts of June 25, 1910, and March 2, 1919. For further details see page 291, Annual Report for 1904; page 776, Annual Report for 1918; page 662, Annual Report for 1938; 628 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 pages 720, 724-725, and 733-734, Annual Report for 1940; pages 692-694, Annual Report for 1941; and page 767, Annual Report for 1945. Existing project. This provides for improvement of the sec- tion of the Intracoastal Waterway from the Caloosahatchee River, Fla., to Anclote River, Fla., to a depth of 9 feet at mean low water and a width of 100 feet, including deepening the ex- isting 100-foot-wide entrance channel at Caseys Pass (Venice Inlet); and for the construction of a highway bridge over the land cut at Venice, the operation and maintenance of the bridge to be assumed by local interests. In the area between Venice and Lemon Bay, the Secretary of the Army, acting through the Chief of Engineers, is authorized to use the original or such other route as may be deemed feasible by the Chief of Engineers and ap- proved by the Secretary of the Army, provided that the cost to United States shall not exceed the cost of the original route. Two parallel jetties 300 feet apart, each 659.4 feet long and consisting of 19 steel-sheet-pile cylinders connected by steel-sheet-pile cur- tain walls, together with the wood-sheet-pile bulkhead extensions and riprap shore revetments, were constructed at the Caseys Pass entrance under a previous project and are maintained under the existing project. The waterway will include the existing im- proved channels in Pine Island Sound from Punta Rasa to Char- lotte Harbor, in Little Sarasota Bay and Sarasota Bay from No- komis to Tampa Bay, through the entrance from the Gulf of Mexico at Caseys Pass (Venice Inlet), and in Boca Ciega Bay from Clearwater Harbor to Tampa Bay. On November 4, 1949, the Secretary of the Army tentatively approved a modification of the route between Caseys Pass and Lemon Bay to provide a channel through Venice approximately paralleling Park Boule- vard. The total length of the waterway is 147.8 miles; the length of the entrance channel at Caseys Pass is 0.67 mile. The mean ranges of tide are 1.7 feet at Punta Rasa, 1 foot at Port Boca Grande, 1.4 feet in Tampa Bay at Anna Maria, and 2 feet at the entrance to Anclote River. The extreme ranges are about 4.5 feet at Punta Rasa, about 3 to 4 feet between Port Boca Grarle and Corey Causeway over Boca Ciega Bay, and about 5.5 feet at the entrance to Anclote River. Southerly winds over the area generally raise the water level by 1 to 1.5 feet; northerly winds lower the water level by 1 to 2 feet. The estimate of cost for new work, approved in 1951, is $5,- 346,000, exclusive of amounts expended on previous projects. The latest (1951) approved estimate for annual cost of maintenance is $87,000. The existing project was authorized by the following river and harbor acts: RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 629 Acts Work authorized Documents Mar. 2, 1945 The 9- by 100-foot channel: deepening the existing H.

June 30, 1948 Use of the original or one of three designated alter- Specified in act. native routes between Caseys Pass and Lemon Bay, provided that the cost to the United States shall not exceed the cost of the original route. May 17, 1950 Use of such previously authorized routes or any Specified in act. other route in the Venice and Lemon Bay area as may be deemed feasible by the Chief of Engineers and approved by the Secretary of the Army. Local cooperation. The act which adopted the project imposed the conditions that local interests furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil- disposal areas for the initial work and for subsequent mainte- nance, when and as required; hold and save the United States free from claims for damages resulting from the improvement; and give assurances satisfactory to the Secretary of War that they will assume maintenance and operation of the highway bridge to be constructed near Venice. The West Coast Inland Navigation District, a special taxing district created by the Florida State Legislature in 1947 to comply with requirements of local coopera- tion, adopted a resolution on July 28, 1947, furnishing assurances of compliance. That resolution was approved by the division en- gineer on September 19, 1947, as satisfactory assurance of com- pliance. Upon request, the district engineer furnished the West Coast Inland Navigation District maps showing the spoil areas and rights-of-way to be acquired for the sections of the waterway from Tampa Bay to Anclote River and from Caloosahatchee River to Tampa Bay on May 7 and July 15, 1948, respectively. The Navigation District has indicated that it is ready to take im- mediate action toward procurement of lands required for rights- of-way and spoil disposal upon request of the district engineer. On April 13, 1950, the West Coast Inland Navigation District adopted a resolution obligating itself to pay $59,770, representing the estimated excess cost for constructing the Park Boulevard route over that of the original route. That resolution was for- warded to the Chief of Engineers on May 5, 1950. Terminal facilities. These consist of one phosphate-loading wharf at Port Boca Grande; 1 municipal concrete pier, 1 rail- way pier, 1 freight wharf, 1 marginal wharf 500 feet long on the terminal inland, and 10 privately owned landings, all at Sarasota; 6 wharves along Boca Ciega Bay; and a number of small, priv- ately owned piers and wharves at various points along the water- way for use of commercial fishing boats and recreational craft. The municipal pier and the freight wharf at Sarasota are open to the public. The railway pier at Sarasota is used mainly for storing Pullman cars. All other piers have highway connections only. The facilities are considered adequate for the existing commerce. 630 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Operations and results during fiscal year. Engineering studies and preliminary plans and specifications cost $431.66 for new work. The expenditures were $382.52. Condition at end of fiscal year. The existing project was about 3 percent completed. Work has been limited to completion of about 28 percent of the required detail planning. Under previous projects, channels, following in general the alinement of the proj- ect waterway, have been dredged and jetties constructed as fol- lows: Work Depth Width Length Dates Feet Feet Miles Channel from Punta Rasa through Pine 7 100 26 April to October 1903.

This provides for a channel 32 feet deep at mean low water and 300 feet wide, increased to 700 feet wide at the bend, from the Gulf of Mexico to Port Boca Grande, just in- side the entrance, thence 10 feet deep and 100 feet wide to the municipal terminal at Maud Street, Punta Gorda, with a turning basin 200 feet square at the outer end of the terminal. The length of waterway included in the project is about 4.5 miles from the Gulf of Mexico to Port Boca Grande, and thence about 25 miles to Punta Gorda. The mean tidal range is 1 foot at Port Boca Grande and 1.4 feet at Punta Gorda. The extreme range is about 3 feet at Port Boca Grande and 3.8 feet at Punta Gorda. Strong southwesterly winds raise the water level about 1.5 feet, and strong northerly and easterly winds lower it about 1 foot. The estimate of cost for new work, revised in 1951, exclusive of amounts expended on previous projects and $15,562.78 con- tributed by local interests, is $428,000. The latest (1951) ap- proved estimate of annual cost of maintenance is $29,000. The existing project was authorized by the following river and harbor acts: 632 REPORT OF CHIEF OF ENGINEERS, U. S.

Deepening of the entrance channel to 32 feet (H. Doc. 186, 81st Cong., 1st sess.) is subject to the con- dition that local interests furnish assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from damages due to construction of the improve- ment. All prior requirements have been fully complied with. Terminal facilities. These consist of a phosphate wharf at Port Boca Grande and a municipal earth-fill pier about 850 feet long, retained by steel-sheet piling, at Punta Gorda. Both wharves are open to the public. Railway connections are available at Port Boca Grande, and highway and railway connections are available at Punta Gorda. The facilities are considered adequate for exist- ing commerce. (For further details see Port Series No. 8, Corps of Engineers.) Operations and results during fiscal year. Condition survey of Charlotte Harbor and entrance channel cost $2,183.36 for main- tenance. The expenditures were $1,448.54. Condition at end of fiscal year. The existing project was about 45 percent completed. A channel 24 feet deep and 300 feet wide from the Gulf of Mexico to Port Boca Grande was dredged be- tween November 1912 and April 1913; was deepened to 27 feet (500 feet wide at the bend) between August and December 1946; and was further deepened to 30 feet (700 feet wide at the bend) between August 1938 and August 1939. The 10-foot channel thence to Punta Gorda was dredged from February to April 1931. The work remaining to be done to complete the project is dredging to deepen the existing entrance channel to 32 feet. When last surveyed the controlling depths were as follows: The entrance channel to Port Boca Grande, 28.3 feet in mid- channel with limiting depths of 28.3 and 27 feet in the left and right outside quarters, respectively, in June 1951; and in the channel to Punta Gorda, 11 feet in April 1950. The costs under the existing project have been $193,964.76 for new work and $675,642.54 for maintenance, a total of $869,- 607.30. The expenditures have been $868,872.48. In addition, $15,- 562.78 were expended from contributed funds for new work in Boca Grande entrance channel. Proposed operations. The balance unexpended June 30, 1951, $1,000, plus an allotment of $76,500 during fiscal year 1952, a total of $77,500, will be applied as follows: RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 633 Accounts payable June 30, 1951.......................... $734.82 Maintenance: Dredge, with U.

Knight Field, Davis Islands, about 2,000 feet long and partially inclosing a landing basin for seaplanes (maintenance to be as- sumed by local interests). The length of the section included in the existing project is about 64.1 miles, including about 7.7 miles in the Hillsboro River and about 3.6 miles in the Alafia River Channel. The plane of reference is mean low water. The mean range of tide is 1.3 feet at the lower end of the bay, 1.6 feet at Port Tampa City, and 1.8 feet at Tampa. The extreme range is about 3.8 feet at the lower end of the bay and 4.8 feet at Tampa. Strong southwesterly winds raise the water level about 1.5 feet. Strong northerly winds, which usually occur in winter, lower the water level about 2 feet. The estimate of cost for new work, revised in 1951, is $20,- 479,300, exclusive of amounts expended on previous projects. The latest (1951) approved estimate of annual cost of maintenance, exclusive of the breakwater at Peter O. Knight Field, is $172,500.

Under date of March 9, 1950, the Chief of Engineers recommended modification of the existing project to provide for removal of snags, wrecks, piling, and similar obstructions from the channel of Hillsboro River between the upstream end of the existing project at the Florida Avenue Bridge and the city waterworks dam, at an estimated cost to the United States of $14,400 for new work with no in- crease in the annual cost of maintenance in addition to that now required, subject to certain conditions of local cooperation (H. Doc. 567, 81st Cong., 2d sess.). Local cooperation. The River and Harbor Act of June 20, 1938 (S. Doc. 164, 75th Cong., 3d sess.), authorized widening the bend between Sparkman Channel and Cut D of Hillsboro Bay Channel by 250 feet, widening Ybor Channel from 300 to 400 feet, and extending the turning basin at the west end of Garrison Channel easterly for 300 feet, subject to the conditions that local interests furnish, free of cost to the United States, necessary rights-of-way and suitable spoil-disposal areas for new work and for subsequent maintenance as required, and move and recon- struct all bulkheads, wharves, buildings, roads, railroad tracks, and all other structures as may be necessary. The River and Harbor Act of March 2, 1945, authorized the further widening of Ybor Channel to 500 feet, widening Spark- man Channel to 400 feet, widening the bend between Garrison and Sparkman Channels, and reducing the widening between Seddon and Garrison Channels from 300 to 150 feet (S. Doc. 183, 78th Cong., 2d sess.), subject to the conditions that the City of Tampa agree to commence and complete promptly the construc- tion of the belt-line railroad and the paving of streets on the north and east sides of Ybor Channel (first required by River and Harbor Act of August 8, 1917, and complied with as regards the west side of the channel) when necessary in the judgment of the Secretary of War; and provided further, that local interests fur- nish, free of cost to the United States, all lands required for the provision of the improvements and for the disposal of dredged material during construction, and for subsequent maintenance as and when required, and construct such bulkheads and retaining walls, and strengthen or move adjacent structures, as may be required to safeguard both the channels and the adjacent lands and structures, all in a manner satisfactory to and approved by the Chief of Engineers and the Secretary of War, and agree to hold and save the United States free from claims for damages resulting from the improvement. In 1945 the Florida Legislature adopted a bill creating the Hillsborough County Port Authority as the governing body and authority of the area defined in the act as Hillsborough County Port District, comprising approximately the northwest quarter and part of the southwest quarter of Hillsborough County. It includes all channel and terminal areas of Tampa and Port Tampa, but excludes the Alafia River and the relatively un- developed area east of the upper harbor. On September 9, 1949, the Hillsborough County Port Authority adopted a resolution RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 637 agreeing to comply with all conditions imposed in Senate Docu- ment 164, 75th Congress, third session. On October 11, 1949, the port authority adopted a resolution agreeing to, and assuming full responsibility for compliance with, the requirements as set forth in Senate Document 183, 78th Congress, second session, except any requirement to extend the trackage of the municipal belt-line railroad (extension not now required in accordance with the provisions of the River and Harbor Act of May 17, 1950), but specifically including the obligation in respect to the portion thereof already completed. The Chief of Engineers accepted those resolutions on November 21 and December 28, 1949, respectively, as satisfactory assurance of compliance. The port authority has furnished, or caused to be furnished, all lands, easements, rights- of-way, and spoil-disposal areas required for new work provided for in those documents. All streets on the west side of Ybor Chan- nel have been paved, and the through streets on the north and east sides have been paved. In addition, the port authority has furnished evidence satisfactory to the district engineer that the United States will be held harmless in the event of sloughing of banks as a result of dredging. The width of Ybor Channel has been restricted to a minimum of 480 feet at some localities to make unnecessary the construction of bulkheads and retaining walls and the strengthening or moving of structures. The River and Harbor Act approved March 2, 1945; authorized certain improvements in Hillsboro River (H. Doc. 119, 77th Cong., 1st sess.) subject to the conditions that local interests fur- nish, free of cost to the United States, all lands, easements, rights- of-way, and suitable spoil-disposal areas for initial work and subsequent maintenance when and as required; agree to make at their expense necessary alterations to structures crossing the river; and hold and save the United States free from claims for damages resulting from the improvement. The Hillsborough County Port Authority has indicated that it will comply with these requirements when it becomes evident that funds will be made available. The work authorized by the River and Harbor Act approved May 17, 1950, is subject to the conditions that for new work responsible local interests give assurances satisfactory to the Secretary of the Army that they will: (a) provide without cost to the United States all lands, easements, rights-of-way, and spoil- disposal areas necessary for construction and subsequent mainte- nance of the project, when and as required; (b) hold and save the United States free from damage due to the construction and sub- sequent maintenance of the works; (c) construct such bulkheads and retaining works, and strengthen or move adjacent structures as may be required, prior to dredging, to safeguard the channels, basins, and adjacent lands and structures, in accordance with plans approved by the Chief of Engineers; (d) provide, prior to or concurrently with the Federal improvement, additional or en- larged slips and berthing space with necessary terminal facilities at Port Tampa City in accordance with plans approved by the Chief of Engineers; (e) open existing terminal facilities in Alafia 638 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 River to all at the same rates and charges that apply to other Tampa Harbor terminals and expand those facilities as and when required to meet the needs of commerce; and (f) open the termi- nal facilities at Tampa Harbor to all on equal terms. The project document further provides: (1) that the existing conditions of local cooperation whereby approval of wharfage charges by the Secretary of War is required (River and Harbor Act of August 8, 1917), be revoked; (2) that the requirements pertaining to the municipal belt-line railroad imposed by the River and Harbor Act of August 8, 1917 (H. Doc. 1345, 64th Cong., 1st sess.) and by the River and Harbor Act of March 2, 1945 (S. Doc. 183, 78th Cong., 2d sess.) be modified so as to require no further extension of trackage with the understanding that the city's obligation with respect to the completed. portion shall remain in force until re- lieved by the Chief of Engineers. All other and prior requirements have been fully complied with. Terminal facilities. There are 57 piers and wharves at Tampa, including 14 on Hillsboro River at Tampa, 28 other piers within the Tampa city limits, 1 at East Tampa, 13 on the slip at Port Tampa City, and 1 on Old Tampa Bay at Rattlesnake, Fla. Those on Hillsboro River are suitable for small vessels drawing up to 11 feet; all others are used by deep-draft vessels. The municipal terminals are on Ybor Channel and consist of a slip 778 feet long, 250 feet wide, with a wharf on either side, on of which has a steel-frame transit shed. The City of Tampa also owns a shore wharf on Hillsboro River and another on Garrison Channel. Forty-eight of the facilities, including the municipal slip, have railway connections, and all have highway connections. The muni- cipal terminals, 1 city wharf, and 10 private terminals are open to the public. The piers and wharves on the various channels are used principally as follows: 39 for general cargo and private commodities, 10 for mooring or berthing vessels at shipyards, and 3 for various industrial purposes; 5 are not in use. The facilities are considered adequate for the existing commerce except at Port Tampa City. (See Port Series No. 17, revised 1947, Corps of Engineers.) Operations and results during fiscal year. New work: Dredg- ing with the contract dredge Orleans to widen Ybor Channel to 500 feet, 76 percent completed at the beginning of the fiscal year, was completed July 21, 1950. Removal of 84,019 cubic yards of material cost $71,964.44. Surveys and preliminary plans and specifications cost $284.07. Maintenance: Dredging, with the U. S. hopper dredge Hyde, to remove critical shoaling and restore project dimensions was performed in the upper harbor between August 6, 1950, and October 31, 1950, and in Egmont Channel between November 1, 1950, and December 29, 1950. A total of 1,392,378 cubic yards, bin measurement, was removed at a cost of $258,487.42. Periodic condition surveys and inspections cost $1,646.25. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 639 The costs for the year were $72,248.51 for new work and $260,- 133.67 for maintenance, a total of $332,382.18. The expenditures were $483,940.74. Condition at end of fiscal year. The existing project was about 50 percent completed. Dredging was begun in August 1899 to provide a channel 24 feet deep and of sufficient width from the Gulf of Mexico to Port Tampa City, and in November 1910 to provide a channel of the same depth in Hillsboro Bay to Tampa. Dredging has been continued intermittently to secure greater depths and widths as authorized from time to time. Egmont Channel, 29 feet deep and 500 feet wide was completed in July 1931, and channels 30 feet deep, 400 feet wide at Mullet Key cut and Tampa Bay Channel cut A, 300 feet wide thence to and in- cluding the Port Tampa Channel, Hillsboro Bay Channel, Seddon Channel, Sparkman Channel, Ybor Channel, and 275 feet wide in Garrison Channel were completed in June 1936. Egmont Reloca- tion Channel, to replace the old channel alinement on Egmont Bar, was dredged 32 feet deep and 600 feet wide from February 1938 to May 1939. Sparkman Channel was widened to a total width of 400 feet and the bends between Sparkman Channel and Cut D of Hillsboro Bay Channel were widened to project dimen- sions between July 1947 and May 1949. A turning basin 2,750 feet long and 550 feet wide was dredged at the entrance to the Port Tampa City terminals between November 1933 and Decem- ber 1935. The turning basin at the entrance to Ybor Channel was completed in July 1947, and that at the west end of Garrison Channel (mouth of Hillsboro River), in May 1949. Ybor Channel was widened to a total width of 500 feet between April and June 1950. A channel 12 feet deep and 200 feet wide in Hillsboro River from the mouth to within 100 feet of the Lafayette Street Bridge was dredged between December 1899 and about June 1905 under a previous project, and has been maintained under the existing project. The breakwater of dredged material at Peter O. Knight municipal airport was constructed from August 1940 to January 1941, and the City of Tampa has formally assumed responsibility for its care, preservation, and maintenance.

WITHLACOOCHEE RIVER, FLA. Location. This river rises in the central part of the peninsula of Florida and flows generally northwesterly and westerly, empty- ing into the Gulf of Mexico about 20 miles southeast of Cedar Key, Fla., and 95 miles north of the entrance to Tampa Bay. (See U. S. Coast and Geodetic Survey Chart No. 1259.), Previous projects. A project for the improvement of the en- trance was adopted by the River and Harbor Act of June 13, 1902. For further details see page 1832 of the Annual Report for 1915, and page 523 of Annual Report for 1934. Existing project. This provides for securing and maintaining a channel 10 feet deep at mean low water and 100 feet wide from the Gulf of Mexico to Port Inglis, just within the river entrance, by dredging and rock excavation; maintaining the channel be- tween the river mouth and Inglis (steam-electric plant) 10 feet deep and generally 70 feet wide; and removing snags, over-hang- ing trees, and loose rock, and cutting through shoals in the upper river, to make a draft of 2 feet available for about half the year as far as Croom (formerly Pembertons Ferry), 85 miles above the mouth. The Second Deficiency Appropriation Act, 1944, approved June 28, 1944, authorized the use of appropriations for rivers and harbors for the improvement, in the interests of na- tional defense and subject to the approval of the Chief of Engi- neers, of the channel between the mouth of the river and Inglis. The authorized work comprises the provision of a practical chan- nel 10 feet deep at mean low water and 70 feet wide, with easing of bends, from Port Inglis to the steam-electric plant at Inglis, by dredging and rock excavation. The lengths of the sections in- cluded in the project are 4.1 miles from the Gulf to Port Inglis, thence 6.4 miles to the steam-electric plant at Inglis, and thence 642 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 about 78.6 miles to Croom. The mean tidal range at the mouth is 2.8 feet and the spring range about 3.5 feet. The effect of the tide is perceptible for about 11 miles above the mouth. Strong southwesterly winds raise the water level at the mouth about 1 foot, and strong northerly winds, which usually occur during the winter, lower the water level about 1.5 feet. Freshets raise the water level in the upper river from 4 to 6 feet and at the mouth about 1 foot. The estimate of cost for new work, revised in 1951, is $659,900, exclusive of amounts expended on previous projects, but including $299,859.38 for the improvement of the channel between the mouth and Inglis. The latest (1951) approved estimate of annual cost of maintenance is $5,500. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1881 Improving river from mouth to Hays Ferry, 79 Annual Report, 1880, pp. 1110- miles. 1119.

Local cooperation. The River and Harbor Act approved July 24, 1946, imposed the condition that local interests agree to fur- nish, free of cost to the United States, all rights-of-way and spoil-disposal areas necessary for the maintenance work when and as required, and hold and save the United States free from damages due to the maintenance work. Terminal facilities. These consist of one small timber dock at Inglis, with shore facilities for fuel-oil storage; one dock at Yankeetown, with shore facilities for gasoline storage; two small docks for handling fish-one each at Yankeetown and Inglis; one small dock at Panasoffkee, open to public use; and several pri- vately owned docks along the river. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Contract work to restore authorized channel dimensions by the removal of shoals, boulders, and other obstructions from the channel between Port Inglis and Inglis, 36 percent completed at the beginning of the fiscal year, was completed August 18, 1950. Totals of 12,800 cubic yards of material, 3,285 cubic yards of rocks or boulders, and 26 obstructions were removed. The cost was $18,430.92. Blasting and layout work was performed by hired labor, in ad- vance of contract shoal removal, at a cost of $2,514.79. Periodic condition surveys and inspections cost $5,177.87. RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 643 The total cost for the year was $26,123.58, all for maintenance. The expenditures were $39,118.80. Condition at end of fiscal year. The existing project as a whole was about 89 percent completed. The entrance channel was about 85 percent completed. A channel 10 feet deep and 85 feet wide from the 10-foot contour in the Gulf of Mexico to Port Inglis was dredged between April 1908 and November 1914. A practical channel 10 feet deep and 70 feet wide, with easing of five sharp bends, from the mouth of the river to the steam-electric plant at Inglis was provided by dredging and rock excavation between June 1945 and March 1946. Removal of snags, overhanging trees, sunken logs, loose rock and boulders and some rock ledges from the river between its mouth and Croom was begun in March 1882 and was practically completed in 1892, thereby enabling light- draft boats to ascend the river to Croom, except at low-water stages. Under permit granted by the Secretary of War on April 16, 1904, a power dam and a lock 134 feet by 36 feet, now owned and operated by the Florida Power Corp., were built about 11.4 miles above the mouth of the river. The dam creates a pool ex- tending nearly to Dunnellon, 24.5 miles above the mouth. The lock, which had been inoperative since installation of the gates in 1916 except for about 7 months during 1926, was restored to op- erating condition in January 1942. When last surveyed, controlling depths were as follows: Gulf of Mexico to Port Inglis, 8.8 feet for a width of 85 feet in June 1951; thence to the power plant at Inglis, 10 feet for a width of 70 feet in June 1951; Inglis to Dun- nellon, 4 feet in May 1940; and thence to head of navigation at Croom, about 2 feet during half the year with 1 foot during low stages. The depths are referred to mean low water, Gulf datum! between the entrance and the dam, and to local low-water stage of the river above that point. Between Dunnellon and Croom, the river was open. The work remaining to be done to complete the project is the 15-foot widening of the entrance channel to Port Inglis. The costs under the existing project have been $584,911.60 for. new work and $175,447.73 for maintenance, a total of $760,- 359.33. The expenditures have been $760,402. Proposed operations. Accounts receivable, June 30, 1951, $49.03, plus an allotment of $79.71 during fiscal year 1953, a total of $128.74, will be applied to the payment of accounts payable, amounting to $6.36, and to defray final costs of condition survey made in fiscal year 1951. The sum of $3,500 can be profitably expended during the fiscal year 1953 for a maintenance condition survey of the 10-foot-depth channel from the Gulf of Mexico to Inglis. 644 REPORT OF CHIEF OF ENGINEERS, U.

ARECIBO HARBOR, P. R. Location. The harbor is on the north shore of Puerto Rico, about 40 miles west of San Juan Harbor. (See U. S. Coast and Geodetic Survey Chart No. 903.) Previous projects. A previous project was authorized by the River and Harbor Act approved August 30, 1935, subject to cer- tain conditions of local cooperation. Local interests were unable to comply with those conditions; and further, the type of deep- water terminal proposed was objectionable to navigation inter- ests. As a result no work was done and no expenditures were made under the project. For further details see pages 1619 and 1620 of Annual Report for 1936. Existing project. This provides for construction of a stone 'breakwater 1,200 feet long extending from Point Morrillos to Cocinera Rock; dredging an entrance channel 25 feet deep at mean low water and 400 feet wide, flared to 650 feet wide at the ocean entrance and widened for the inner 650 feet of its length to form a maneuvering area of the same depth and 900 feet wide, fronting the proposed deep-water terminal. The mean tidal range is 1.1 feet; the extreme varies between about 1 foot below and about 2.8 feet above mean low water. 'The actual cost of new work was $1,128,075, excluding $288,- 000 contributed by local interests. The latest (1937) approved estimate of annual cost of maintenance is $20,000. The existing project was adopted by the River and Harbor Act of August 26, 1937. (See Rivers and Harbors Committee Doc. 43, 75th Cong., 1st sess.) Local cooperation. Plans and specifications of a bulkhead wharf and terminal to be constructed by the Municipality of Arecibo were approved by the Chief of Engineers on December 19, 1940, and by the Secretary of War on December 23, 1940. Plans for a provisional wharf to be constructed of native timber to serve the needs of Arecibo Harbor until conditions again became normal, after which it was proposed to construct the permanent terminal in accordance with plans already approved, were approved by the Chief of Engineers on February 1, 1943. This provisional wharf RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 645 was never constructed. A temporary lighterage wharf was built to serve such traffic as might use the port until a permanent ter- minal could be provided. On May 27, 1947, the Puerto Rico Trans- portation Authority, an agency of the Government of Puerto Rico which now has jurisdiction over the operation of Arecibo Harbor, submitted plans and specifications for a permanent deep-water terminal to supersede the plans and specifications approved by the Secretary of War on December 31, 1940. Those plans were approved by the Chief of Engineers on September 17, 1947. The terms of local cooperation in reference to terminal facilities have not been complied with. Terminal facilities. Other than the temporary lighterage wharf, no terminal facilities are available at Arecibo Harbor. The proposed marginal wharf and terminal, to be provided as local cooperation in accordance with plans approved September 17, 1947, are considered adequate for normal commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project was com- pleted in 1944. The controlling depth is 25 feet except for a shoal area in the south half of the outer entrance channel with a least depth of 24 feet and an area at the southeasterly corner of the maneuvering area, extending about 400 feet west from the east- erly limit line and about 150 feet north from the southerly limit line, with depths decreasing from 25 feet to 1 foot. The total costs and expenditures of the existing project to the end of the fiscal year were $1,418,504.88, of which $1,128,074.86 United States funds and $288,000 contributed funds were for new work and $2,430.02 United States funds were for maintenance. Proposed operations. An allotment of $80,000 during the fiscal year 1952 will be applied to maintenance for reconstruction, by contract, of the damaged and deficient rock sections of the stone breakwater, January to June 1952.

Doc. 215, 72d Cong., 1st sess., and Rivers and Harbors Committee Doc. 1, 73d Cong., 1st sess.). The latest published map is in the former document. Local cooperation. Fully complied with. Terminal facilities. The terminals consist of two piers, used by lighters, located on shoal water in the east-central section of the harbor; and a modern deep-water terminal in the northeast section of the harbor, consisting of a bulkhead wharf about 1,270 feet long with a storage shed 800 feet long and 60 feet wide im- mediately shoreward thereof. The facilities appear adequate for the normal needs of commerce. Operations and results during fiscal year. Maintenance: Be- tween May 17, 1951, and June 11, 1951, the U. S. hopper dredge Hyde removed 221,412 cubic yards, bin measurement, from the approach channel and maneuvering area at a cost of $47,352.69. The cost for the year was $47,352.69, all for maintenance. The expenditures were $48,926.49, Condition at end of fiscal year. The existing project was com- pleted in 1984. At the end of the fiscal year, controlling depth was about 29.2 feet in the approach channel and 31 feet in the maneuvering area. The total cost of the existing project to June 30, 1951, was $297,070.63, of which $21,000 of regular funds and $147,186.69 of Public Works funds were for new work, and $128,883.94 of regular funds were for maintenance. The expenditures were $298,644.43. Proposed operations. The balance unexpended and accounts receivable June 30, 1951, $9,647.31, minus an revocation of $1,000 during fiscal year 1952, a net amount of $8,647.31, will be applied to maintenance for demobilization of the U. S. hopper dredge Hyde to the United States, in October 1951. No work is scheduled during fiscal year 1953.

The water hyacinth is found in the fresh-water streams and lakes in various parts of the district. Existing project. This provides for the destruction or removal of the water hyacinth in the navigable waters of the State so far as they constitute an obstruction to commerce, using any me- chanical, chemical, or other means not injurious to cattle, and the use of log booms to close sloughs and backwaters as an auxiliary means. No estimate of the final cost of the work has been made. The latest (1951) approved estimate of annual cost of mainte- nance is $100,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1899 For the construction and operation of a suitable ves- H.

Mar. 3, 1905 Prohibits the use of any chemical process injurious Do. to cattle. Local cooperation. None required. Operations and results during fiscal year. Upper St. Johns River system: Maintenance of the Camp Rosa boom, 9.7 miles below Palatka, operation of traps to aid in the control of hya- cinths, destruction of hyacinth jams, and spraying of hyacinths was accomplished throughout the fiscal year at a cost of $52,- 641.72. Okeechobee Waterway and tributary streams: Hyacinth destruction operations were conducted by hired labor as necessary throughout the fiscal year at a cost of $4,936.18. Withlacoochee River and tributaries: Hyacinth destruction operations were conducted by hired labor as necessary through- out the fiscal year at a cost of $6,150.09. The total cost of all work was $63,727.99 for maintenance, all by hired labor. The expenditures were $60,975.47. Condition at end of fiscal year. The project is for mainte- nance. A chemical for spraying was tested in August and Sep- tember 1900; spraying was begun in November 1902, but was discontinued in February 1906 because of the injurious effect on cattle. Subsequent operations through the fiscal year 1938 con- sisted chiefly of breaking up jams and drifting, except from No- vember 1909 to February 1918 when an elevator was used to either place the plants on shore or to form them in deep piles that could be carried away by the currents. Later operatons, through April 1948, have consisted principally of construction of tem- porary and permanent traps at strategic points, and shredding with cutter boats. Spraying with a new chemical, which is not injurious to cattle or fish, was begun in March 1948 to supple- ment other methods, and has proven to be highly effective. Since RIVERS AND HARBORS-JACKSONVILLE, FLA., DISTRICT 651 that date, spraying has gradually become the principal method of destruction, supplemented by the methods previously in use. Dur- ing September 1949, large areas of hyacinths in the St. Johns River were sprayed by airplane, with very satisfactory results. At the close of the fiscal year, the St. Johns River and tributary streams, Okeechobee Waterway, and Hillsboro and Withlacoochee Rivers were open and in good condition. The total cost has been $1,228,290.47 for maintenance. The expenditures have been $1,226,933.45. Proposed operations. The balance unexpended and accounts receivable June 30, 1951, $1,914.29, plus an allotment of $75,000 during fiscal year 1952, a total of $76,914.29, will be applied as follows: Accounts payable June 30, 1951 ........................... $1,698.02 Maintenance: Removal or destruction, by hired labor, of water hyacinths in the St. Johns River and tributary streams, July 1951 to June 1952... $62,766.27 Removal, by contract, of the Camp Rosa boom, which was placed across the St. Johns River near Palatka several years ago as a hyacinth- control measure, January to February 1952... 3,700.00 Removal or destruction, by hired labor, of water hyacinths in Withlacoochee River and tribu- tary streams, July 1951 to June 1952........ 5,000.00 Removal or destruction, by hired labor, of water hyacinths in the Okeechobee Waterway and tributary streams, July 1951 to June 1952... 3,000.00 Removal or destruction, by hired labor, of hya- cinth jams at bridges on the Hillsboro River and other navigable waterways on the Gulf coast as required, July 1951 to June 1952.... 750.00 75,216.27 Total for all work ............................... 76,914.29 The sum of $75,000 can be profitably expended during fiscal year 1953 for maintenance for control and destruction, by hired labor, of water hyacinths in the various navigable waters in the district as required.

CENTRAL AND SOUTHERN FLORIDA Location. The project area includes Lake Okeechobee, its regulatory outlets, and a large portion of the Everglades and east coast areas to the south, all near the southern end of the Florida Peninsula. (See U. S. Coast and Geodetic Survey Charts Nos. 473, 1247, 1248 and 1289 and "Florida Everglades Drainage Dis- FLOOD CONTROL--JACKSONVILLE, FLA., DISTRICT 667 trict," Soil Conservation Service maps Nos. 1524 to 1561, July 1946.) Lake Okeechobee and its regulatory outlets lie in Palm Beach, Martin, Okeechobee, Glades, Hendry, and Lee Counties. St. Lucie Canal flows from the lake to the Atlantic Ocean; the Caloosa- hatchee River, from the lake to the Gulf of Mexico. The lower east coast region embraces the populous urban and agricultural areas in Dade, Broward, and Palm Beach Counties. The region lies along the coast from the St. Lucie Canal south to near the tip of the State, and extends 9 to 20 miles inland. The conservation areas lie in Dade, Broward, and Palm Beach Counties west of the lower east coast region, and include 1,344 square miles of the Everglades suitable only for water and wild- life conservation. Lake Okeechobee agricultural area lies south of the lake, mostly in western Palm Beach County, but including part of Hendry County. The area embraces 1,130 square miles of muck and peat land which is suited for long-term agricultural use. Previous projects. Previous projects consist of completed works for control of Lake Okeechobee included in and con- structed under the navigation project for Okeechobee Waterway, Fla. (formerly Caloosahatchee River and Lake Okeechobee Drain- age Areas, Florida) under provisions of River and Harbor Acts approved July 3, 1930, and August 30, 1935. For further informa- tion, see pages 877-882, Annual Report for 1948, and page 785, Annual Report for 1949. Existing project. This provides for modification and expan- sion of the previous project to include the first phase of the com- prehensive plan for flood control and other purposes in central and southern Florida, as recommended by the Chief of Engineers in House Document 643, Eightieth Congress, second session; and authorizes the appropriation of $36,300,000 for partial accom- plishment of that plan. The first phase of the plan provides for the following: (a) Everglades-lower east coast area: (1) An east-coast pro- tective levee from the Homestead area north to West Palm Beach Canal; (2) improvements for partial completion of con- servation areas for water impoundment and flood discharge in the Everglades area west of the east-coast protective levee, in- cluding levees within the conservation area separating it into three parts, with gated spillways for discharge of water from one part to the next and, finally, through Tamiami Trail to the undeveloped area to the south, and a bridge culvert where Tami- ami Trail intersects the proposed canal and levee on the west side of the conservation area; (3) local protection works in the area along the east coast from northern Palm Beach County to southern Dade County, including complete protective works in the Davie agricultural area, canal improvements and enlarge- ments, new canals, spillway-headworks at the edge of the con- servation area, bridge crossings, outlet barriers, conduits, and a pumping station for the Davie agricultural area. 668 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 (b) Okeechobee-Everglades area: (1) A levee and canal en- circling the developed portion of the Lake Okeechobee agricul- tural area from Caloosahatchee River via Bolles Canal to Miami Canal, thence south on Miami Canal about 9 miles, thence east- ward to Hillsboro Canal, thence southeastward to the limit of the agricultural area, thence northward crossing West Palm Beach Canal and continuing to -St. Lucie Canal; (2) enlargement of Miami, North New River, Hillsboro, and West Palm Beach Canals within the protected area; (3) five feeder canals within the pro- tected area; (4) four pumping stations at Lake Okeechobee and pumping stations at the eastern edge of the protected area on West Palm Beach and Hillsboro Canals, with installation of par- tial pumping capacities; (5) a spillway at the eastern edge of the agricultural area on the new canal crossing West Palm Beach Canal; (6) improving control of Lake Okeechobee by enlarging St. Lucie Canal to planned dimensions, including modification of spillways and structures; (7) a spillway at Moore Haven, with an outlet canal to Caloosahatchee River; (8) enlargement of Caloosahatchee River to provide increased discharge capacity; (9) enlargement of existing Lake Okeechobee levees, including paving and revetment, and construction of levees on northeast and northwest shores of Lake Okeechobee; (10) initiation of con- struction and operation of a system of meteorological and hydro- logical stations; and (11) under maintenance, the operation and care of the spillway to be constructed at Moore Haven and the maint spillways of the conservation area. Upon completion, local interests are to assume maintenance and operation of all works in subparagraphs (a) and (b) above, ex- cept the gated spillways referred to in subparagraph (a) and features (6) through (11) in subparagraph (b), which works will be operated and maintained by the United States. In addi- tion, the project includes maintenance (since July 1, 1950) of control works completed: with river and harbor funds under the previous navigation, project for Okeechobee Waterway, Fla. (formerly Caloosahatchee River and Lake Okeechobee Drainage Areas, Florida), as follows: (a) A levee about 67.8 miles long from Fisheating Creek to St. Lucie Canal, following in general the south shore of the lake, and a north-shore levee 15.74 miles long (those levees are to be improved and enlarged under the existing project); (b) four auxiliary floodway channels extend- ing into Lake Okeechobee at or near Liberty Point, mouth of Fisheating Creek, mouth of Kissimmee River, and mouth of Taylor Creek; (c) collection and evaluation of meteorological data; and (d) operation and care of spillways at the St. Lucie and Ortona locks, 5 hurricane gates on Lake Okeechobee, 16 drainage culverts through the west-, south-, and east-shore levees and 4 on the north shore of Lake Okeechobee, 16 drainage spill- ways along the St. Lucie Canal, and an intercommunicating radiotelephone network of 8 stations.

Lake Okeechobee is maintained, insofar as possible, between elevations 12.56 and 15.56 feet, mean sea level (14 and 17 feet, Lake Okeechobee datum). :'The estimate of cost for new work, revised in 1951, is $68,- 878,000 United States funds and $10,878,000 contributed funds, exclusive of river and harbor funds expended on previous proj- ects. The latest (1951) approved estimate for annual cost of maintenance is $355,200, including $66,900 for operation and care of protective works. The existing project was authorized by the following flood control acts: Acts Work authorized Documents June 30, 1948 For the first phase of the comprehensive plan for H.

Doc. 643, 80th Cong., 2d sess.), imposed the conditions that local interests shall provide all lands, easements, and rights- of-way; make a cash contribution of 15 percent of the estimated construction cost for each part of the work prior to its initiation (with the provision that the total cash contribution for the en- tire comprehensive prbject shall not exceed $29,152,000) ; and furnish assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from damages due to the construction and operation of the works and that they will maintain and operate all the works after completion in accord- ance with regulations prescribed by the Secretary of the Army, except the levees, channels, locks, and control works of the St. Lucie Canal, Lake Okeechobee, and Caloosahatchee River, and the main spillways of the conservation areas. In May 1949, the Florida State Legislature passed legislation providing for creation of districts for flood control, reclamation, conservation, and allied purposes in cooperation with the United 670 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 States; for creation of the Central and Southern Florida Flood Control District, and for consolidation of the former Everglades Drainage District with that district; and for other measures nec- essary for full compliance with all requirements of local coopera- tion. A resolution adopted August 1, 1949, by the Central and Southern Florida Flood Control District, assuming full responsi- bility for compliance with the requirements of local cooperation as set forth in the project document, was accepted by the Chief of Engineers on November 25, 1949, as satisfactory assurance of compliance. The Flood Control District has furnished rights-of- way and other interests in land, and has contributed the required 15 percent of the estimated construction cost for each feature of the project, when and as requested by the district engineer. In response to a request of local interests on June 10, 1950, urg- ing construction of the eastern boundary levees of the conserva- tion areas to an intermediate grade, the Chief of Engineers out- lined a general policy permitting such construction, provided that local interests agree to maintain the levees at those heights pend- ing completion to full grade. The Central and Southern Florida Flood Control District has agreed to assume full responsibility for maintenance of the levees so constructed. Operations and results during fiscal year.

The spillways at Ortona and St. Lucie locks, 5 hurricane gates on Lake Okeechobee, 16 drainage culverts through the west-, south-, and east-shore levees and and 4 on the north shore of Lake Okeechobee, 16 drainage spillways along the St. Lucie Canal, and an intercommunicating radiotelephone net- work of 8 stations were operated and maintained. Hurricane gate No. 6 was dewatered by hired labor for minor repairs and paint- ing by contract between April 19 and May 16, 1951. All above- water surfaces of the gate were thoroughly cleaned and painted with alluminum paint, and all under-water surfaces and struc- tural members were cleaned by sand-blasting prior to the appli- cation of four coats of bituminous paint. The costs for the year were $14,785.98 for operations, $21,132.58 for ordinary repairs, and $1,030.99 for improvement and reconstruction, a total of $36,949.55, including $3,767.17 for work done by contract. Regulation: Throughout fiscal year 1951 regulation of Lake Okeechobee consisted of maintaining lake stages as nearly as possible between elevations 12.6 and 15.6 feet, mean sea level. Effective May 29, 1951, the plan of regulation was modified slightly to regulate the lake as far as possible between 13.0 and 15.0 feet, mean sea level. The plan of regulation is as follows: a. The lake would be drawn down to 13 feet on June 1 each year, to provide adequate capacity for hurricane rainfall. b. During the rainy season, June through October, the lake would be permitted to rise to about 15 feet to provide adequate storage to meet water demands during the winter growing season. Maintenance of stages above the lower elevation is necessary for navigation in Okeechobee Waterway; the upper limit provides for water-supply and flood-control requirements. Average rain- fall over Lake Okeechobee was 41.45 inches for the year. October was the month of heaviest rainfall, with 8.22 inches. Average observed pan evaporation was 60.07 inches, which is convertible to 46.8 inches evaporation from the water surface. In general, lake stages did not fluctuate greatly. The greatest rise, 0.8 foot, occurred during the 7-day period, October 12-18, 1950, Lake stages, referenced to mean sea level, varied from a maximum of 13.98 on November 21, 1950, to a minimum of 12.65 on June 12, 1951. Average weekly inflow from the tributary area varied from about 650 to 9,950 cubic feet per second and totaled about 1,183,000 acre-feet. Because of the relatively low lake stages dur- ing this fical year, no regulatory discharge was required. Non- regulatory discharge, as effected through the Miami, North New River, Hillsboro, and West Palm Beach Canals and various pump units, to meet agricultural demands and other purposes, varied from about 10 to 1,400 cubic feet per second, and totaled about 669,000 acre-feet. A small hurricane passed north-northwestward over the center of Lake Okeechobee during the morning of October 18, 1950. The barometer read 28.70 inches at hurricane gate structure No. 3 at Lake Harbor. Five-minute-average wind velocities of 72 miles an hour from the east-northeast occurred at lake stations Nos. 14 and 17, located on the lake near the south 674 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 shore, and gusts to 95 miles an hour were recorded at hurricane gate structure No. 3. Associated rainfall average 6.24 inches over the lake. Regulatory discharge was not ncessary as a result of the passage of that hurricane. The total costs for the year were $3,397,868.03, as follows: New work, $2,670,796.78, including $2,968,181.23 United States funds and -$297,384.45 contributed funds; maintenance, $690,- 121.70; and operating and care, $36,949.55. Total expenditures were $3,101,707.14 from Federal funds and -$297,384.45 from contributed funds. Condition at end of fiscal year. The project was about 5 percent completed. Features constructed under previous projects for the Okee- chobee Waterway, Fla., are as follows: A levee 67.8 miles long from Fisheating Creek to St. Lucie Canal, following in general the south shore of the lake, January 1932 to March 1936; a north- shore levee 15.74 miles long, July 1936 to February 1938; the spillway at Ortona lock, November 1934 to August 1937; 4 auxiliary floodway channels extending into Lake Okeechobee at or near Liberty Point, mouth of Fisheating Creek, mouth of Kis- simmee River, and mouth of Taylor Creek, June 1932 to Febru- ary 1938; 5 hurricane gates through the levees at entrance to canals at Clewiston, Lake Harbor, South Bay, Canal Point, and Taylor Creek, November 1933 to December 1936; 16 drainage culverts through the west-, south-, and east-shore levees, and 4 similar culverts through the north-shore levee, December 1933 to December 1936; and 16 drainage spillways at drainage open- ings along the banks of the St. Lucie Canal, November 1934 to September 1935. Planning for the existing project was begun in November 1948. Construction has been accomplished as follows: Levee 35A, Jan- uary to July 1950; levees 35 and 36, March 1950 to May 1951; canal 42, June to August 1950; and levee 43, September to Octo- ber 1950.

GULF INTRACOASTAL WATERWAY BETWEEN APALACHEE BAY, FLA., AND THE MEXICAN BORDER (MOBILE DISTRICT) Location. This section of the Gulf Intracoastal Waterway ex- tends generally westward from Apalachee Bay through Ochlocko- nee Bay, Ochlockonee, Crooked, and Carrabelle Rivers, and St. George Sound to Apalachicola Bay; thence through Apalachicola River, Jackson River, Lake Wimico, Searcy Creek, a land cut, and Wetappo Creek to St. Andrew Bay, Fla.; thence through a land cut to Choctawhatchee Bay, Fla.; thence through Santa Rosa Sound to Pensacola Bay, Fla.; thence through Big Lagoon and Old River, Fla., Perdido Bay, Fla. and Ala., Bay La Lanche, Wolfe Bay, Portage Creek, Oyster Bay, and Bon Secour Bay, Ala., to Mobile Bay, Ala.; thence through Mississippi Sound, Miss., and Lake Borgne, La., to the Rigolets. Previous projects. Adopted by the River and Harbor Acts approved May 23, 1828, and July 25, 1912, for the section between Mobile Bay and Mississippi Sound. For further details see page 906, Annual Report for 1930. Existing project. This provides for a waterway 12 feet deep and 125 feet wide at mean low water, except in the section be- tween Mobile Bay, Ala., and the Rigolets, La., where the width is to be 150 feet, from the vicinity of Apalachee Bay, Fla., to the Rigolets, La.; the construction of a movable span in the Georgia, Florida & Alabama Railroad bridge crossing the Ochlockonee River near McIntyre, Fla.; and for conditional acquisition of the Gulf County Canal, Fla., connecting St. Joseph Bay with the Intracoastal Waterway, and its righteof-way, free of cost to the United States, and enlargement of the canal to a depth of 9 feet and a width of 100 feet. The estimated cost of new work, revised in 1951, is $6,667,000. The latest (1951) approved estimate for annual cost of mainte- nance is $246,000.

The requirements of local cooperation for this project have been fully complied with except for the section from Apalachee Bay to Carrabelle, Fla. The requirements of local cooperation for the section from Apalachee Bay to Carrabelle, Fla., provide that local interests undertake all necessary modifications of bridges over the water- way, except the constructon of a movable span in the Georgia, Florida & Alabama Railroad bridge over the Ochlockonee River near McIntyre, Fla., furnish, free of cost to the United States, necessary rights-of-way and suitable spoil-disposal areas for new work and for subsequent maintenance as required, and release the United States from all claims for damages incidental to the work of improvement. Conditions of local cooperation required by the 9- by 100-foot project authorized by the River and Harbor Act of August 26, 1937, were fulfilled with the exception of the provision concerning alteration of the Georgia, Florida & Alabama Rail- road bridge at McIntyre, Fla., which condition was removed by authority of the River and Harbor Act of March 2, 1945. Local interests were notified January 9, 1951, of the conditions of local cooperation as altered by the authorization of a 12- by 125-foot waterway in Public Law 675, Seventy-seventh Congress (July 23, 1942) and by revised regulations pertaining to bridge clearances across the Gulf Intracoastal Waterway. Terminal facilities. Terminal facilities available for public use are located at Carrabelle, Apalachicola, Panama City, and Pensa- cola, Fla.; Mobile and Bayou La Batre, Ala.; Pascagoula, Biloxi, Gulfport, Pass Christian, and Bay St. Louis, Miss. These facili- ties are considered adequate for existing commerce. Operations and results during fiscal year. The erosion protec- tive works on the Choctawhatchee Bay-West Bay section of the 690 REPORT OF CHIEF OF ENGINEERS, U. S.

ST. MARKS RIVER, FLA. Location. This river, 17 miles long, rises about 14 miles south- east of Tallahassee, Fla., and flows southerly into the Gulf of Mexico, 116 miles east of the new entrance to St. Andrew Bay. (See U. S. Coast and Geodetic Survey Chart No. 1261.) Previous projects. Provision was made for the removal of ob- structions between 1824 and 1844, but apparently under no defi- nite project. For further details see page 686, Annual Report for 1938. Existing project. This provides for a channel 10 feet deep, 100 feet wide at mean low water, and about 8.5 miles long on suitable alinement and with greater width where necessary at bends, from the 10-foot contour in Apalachee Bay to the town of St. Marks, with a turning basin of the same depth and 200 feet square at the latter point, and for the removal of snags and similar obstructions from the present channel between St. Marks and Newport, about 3 miles. The extreme tidal range, except during storms, is between 3 and 4 feet. The mean range of tides is 2.4 feet. The project has been completed at a cost of $193,730.64 for new work, exclusive of amounts expended on previous projects. The latest (1951) approved estimate of annual cost of mainte- nance is $1,500.

For work authorized in accordance with House Document 453, Seventieth Congress, RIVERS AND HARBORS--MOBILE, ALA., DISTRICT 693 second session, and Rivers and Harbors Committee Document 77, Seventy-fourth Congress, second session, local interests are re- quired to furnish necessary spoil-disposal areas for subsequent maintenance as required. Terminal facilities. The terminal facilities on this stream con- sist of small wooden wharves and docks at St. Marks and New- port, used for transferring fish from small fishing craft to cold storage, for unloading petroleum products, for refueling fishing and pleasure craft, and as berths for the small boats located there. They are owned by local residents and by petroleum com- panies. None is publicly owned, but a privately owned dock with 200 feet of frontage at St. Marks is open to the public. There are small marine ways at both St. Marks and Newport. The faci- lities are considered adequate for existing commerce. Operations and results during fiscal year.

APALACHICOLA, CHATTAHOOCHEE, AND FLINT RIVERS, GA. AND FLA. Location. The Apalachicola River is formed at the southwest corner of the State of Georgia by the junction of the Chattahoo- chee and Flint Rivers and flows south 108 miles, emptying into Apalachicola Bay. The Florida River enters the Apalachicola River from the east, 45.4 miles above its mouth, and the River Styx also enters from the east, 36.7 miles above its mouth. (See U. S. Coast and Geodetic Survey Chart No. 1262.) The Chattahoochee River, 418 miles long, rises in northeast Georgia and flows southwesterly to West Point, and thence south- erly to join the Flint River at the southwest corner of Georgia, forming the Apalachicola River. (See U. S. Geological Survey maps for northwest Georgia.) The Flint River, 330 miles long, rises in west-central Georgia, flows generally southeasterly to Albany, and thence southwest to the southwest corner of the State, where it joins the Chatta- hoochee River to form the Apalachicola River. (See U. S. Geo- logical Survey maps for southwest Georgia.) Previous projects. Expenditures on the Apalachicola River were made between 1828 and 1831, but apparently under no defi- nite project. In 1835 and 1836, appropriations were made for the Chipola River. For further details see page 690, Annual Re- port for 1938. Projects for the Apalachicola River were adopted by the River and Harbor Acts of June 23, 1874, June 13, 1902, January 6, 1934, and June 20, 1938. For further details see the existing project for Apalachicola River, page 568, Annual Report for 1944. Projects for the Flint River, Ga., were adopted by River and Harbor Acts of June 23, 1874, and June 14, 1880. For further details see the existing project for Flint River, Ga., page 570, Annual Report for 1944. The River and Harbor Act of July 13, 1892, made an appro- priation for the section of the Chattahoochee River between West Point and Franklin, Ga., and appropriations therefor were con- tinued until 1899, when they were discontinued. For further de- tails see page 1834, Annual Report for 1915, and page 696, An- nual Report for 1938. The River and Harbor Act of June 23, 696 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 1874, adopted the project for the Chattahoochee River from its mouth to Columbus, Ga. For further details see existing project for that river on page 572, Annual Report for 1944. For total cost and expenditures on all previous projects see Cost and Financial Summary for the Apalachicola, Chattahoochee, and Flint Rivers, Ga. and Fla., for the fiscal year 1945. Existing project. Prior to the River and Harbor Act approved March 2, 1945, the existing project for the Apalachicola River provided for a channel therein 6 feet deep at low water and 100 feet wide, to be secured by removing snags and overhanging trees and by widening and straightening Moccasin Slough, for a channel 5 feet deep and 60 feet wide through the cutoff, Lee Slough, and lower Chipola River, together with snagging and dredging to a depth of 6 feet the lower 2,500 feet of Styx River and improving of Florida River by dredging a new outlet 6 feet deep, 80 feet wide, and about 600 feet downstream of its present mouth; for the Chattahoochee River, a channel 4 feet deep at low water and 100 feet wide from the mouth to Columbus, Ga., 164 miles, by removing timber obstructions, dredging, contrac- tion works, and shore protection; and for the Flint River, a chan- nel 100 feet wide and 3 feet deep at extreme low water from the mouth to Albany, 103 miles, to be obtained by dredging, rock excavations, contraction works, and removal of snags, together with a channel for light-draft steamers at moderate stages from Albany to Montezuma, 79 miles, to be obtained by removing loose rocks, snags, and overhanging trees. The River and Harbor Act of March 2, 1945, approved the gen- eral plan presented in House Document No. 342, Seventy-sixth Congress, first session, which document contains the latest published map, for the full development of the Apalachicola, Chattahoochee, and Flint River system in the combined interest of navigation and power, and authorized for the initiation and partial accomplishment of that plan modification of the then- existing projects for the Apalachicola, Chattahoochee, and Flint Rivers to provide for the construction of two of the locks and dams for the 9-foot project, one at Fort Benning and one at the junction, supplemented by dredging and contraction works, to provide a navigable depth of 6 feet to Columbus on the Chatta- hoochee and to Bainbridge on the Flint at an estimated cost for new work of $6,500,000, with annual maintenance of $200,000 in addition to that previously authorized. The remaining elements of the approved plan included navigation-power dams with locks at the Florence, Fort Gaines, Columbia, and Paramore Landing sites on the Chattahoochee between the Junction and Fort Ben- ning sites; storage-power reservoirs on the upper Chattahoochee at the Roswell, Cedar Creek, and Lanier sites; storage-power reservoirs on the upper Flint at the Woodbury No. 2, Potato Creek, and Auchumpkee Creek sites; dredging, cutoffs, contrac- tion works, or other open-river methods, to provide, with the aforementioned dams and flow regulation, channels 9 feet deep and 100 feet wide from the mouth of the Apalachicola River to Columbus, 7 feet deep and 100 feet wide in the Flint River from RIVERS AND HARBORS--MOBILE, ALA., DISTRICT 697 its mouth to Bainbridge, and 5 feet deep and 100 feet wide thence to Albany, at an estimated construction cost to the United States of $66,629,000 for the full development. The River and Harbor Act of July 24, 1946, approved modifi- cation of the general plan presented in House Document 342, Seventy-sixth Congress, first session, to include the improvements now proposed by the Chief of Engineers in lieu of the correspond- ing works of that plan, and authorized for the initiation and partial accomplishment of the modified plan the construction of Buford multipurpose reservoir, Fort Benning lock and dam, and the Upper Columbia and Jim Woodruff, formerly Junction, multi- ple-purpose developments, and supplemental channel work to provide a channel depth of 9 feet for a minimum width of 100 feet in the Apalachicola River, to Columbus, Ga., on the Chatta- hoochee River, 268 miles, and to Bainbridge, Ga., on the Flint River, 29 miles above its junction with the Chattahoochee River.

The estimated cost for new work, revised in 1951, is $147,291,- 000. The latest (1951) approved estimated annual cost for main- tenance is $1,085,000 (includes $875,000 for operating and care). The mean range of tide at the mouth of the Apalachicola River is 1.6 feet; at the point where the river is formed the variation between low and high water is about 37 feet. On the Chattahoo- chee River, the variation between average low and high water is about 20 feet, and the extreme fluctuation is 65.3 feet at Eufaula. On the Flint River, the extreme fluctuation of stage due to floods was 40 feet, while the average variation between low and high water is about 21.5 feet. 698 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Local cooperation. This provides that local interests agree to furnish, free of cost to the United States, all lands, easements, rights-of-way, and spoil-disposal areas, as and when required, for provision and maintenance of the channel in Apalachicola River below Jim Woodruff Dam, to maintain and operate at their ex- pense all utility and highway facilities which are relocated or otherwise altered as a part of the improvement, to provide suit- able public terminal facilities open to all on equal terms, and to hold and save the United States free from damages which might arise from the construction of the improvement. Terminal facilities. At Apalachicola, Fla., the facilities consist of several marginal pile-and-timber wharves. The landing at Blountstown, Fla., is a natural one. A private wharf at River Junction, Fla., is used for landing and storing sand and gravel. On the Flint River there is a natural landing at Bainbridge, Ga., and also at Albany, Ga. On the Chattahoochee River the terminals consist of natural landings at Columbus, Ga., and Eufaula, Ala., and a masonry marginal landing at Columbus. These facilities are considered adequate for the existing commerce. Operations and results during fiscal year. New work: Jim Woodruff Dam.

The total cost was $6,543,542.73, of which $6,538,549.28 was for new work and $4,993.45 for maintenance. The expenditures were $6,351,704.25. Condition at end of fiscal year. Permanent housing and con- struction office at Jim Woodruff Dam were completed. Construc- tion of the lock and fixed-crest spillway was in progress and the east-bank access road was completed. Plans and specifications were about 81 percent completed. Construction of saddle dike No. RIVERS AND HARBORS--MOBILE, ALA., DISTRICT 699 3 and spillway at Buford Dam was completed, construction of ac- cess road was commenced, and plans and specifications were about 41 percent completed. The definite project reports for the Upper Columbia and Fort Benning dams were in progress. The con- trolling depths in the channels at the times shown were as fol- lows: Apalachicola River, 4.5 feet, June 1950; the Cutoff, Lee Slough and Lower Chipola River, 5 feet, October 1943; mouth of Florida River and River Styx, 6 feet, October 1947; Chattahoo- chee River, mouth to Columbus, 3 feet, June 1945; Flint River, mouth to Bainbridge, 2.6 feet, and Bainbridge to Albany, 1.5 feet, June 1941. Ordinarily, boats drawing 5 feet can operate throughout the year on the Apalachicola River at a stage of zero on the River Junction gage. Greater depths are usually available from January to July of each year. On the Chattahoochee River, vessels drawing less than 3 feet may operate throughout the year, and 5 feet can ordinarily be carried from December to June. The head of boat traffic on that river is Columbus, Ga. On the Flint River, greater depths than those shown are generally avail- able between November and June of each year. The head of navi- gation for boat traffic on that river is Albany, Ga. The work remaining to be done to complete the project consists of improv- ing the channel of the Apalachicola River from the mouth to Jim Woodruff Dam, completing construction of Jim Woodruff Dam, and constructing Upper Columbia lock and dam, Fort Benning lock and dam, and Buford Dam.

This is one stream; it rises in central Alabama be- low Union Springs, flows southwesterly to Florida State line, thence southerly through Florida to Escambia Bay, an arm of Pensacola Bay. That part of the stream in Alabama, about 168 miles long, is known as Conecuh River; that in Florida, 651/2 miles long, is know as Escambia River. (See U. S. Coast and Geodetic Survey Chart No. 1265.) Previous projects. The sum of $5,000 was appropriated in the River and Harbor Act of March 2, 1833, for improving the navi- gation of the Escambia River. The River and Harbor Act of August 2, 1882, adopted the original project modified by the act of March 2, 1907. Work under the existing project was begun in 1881. For further details, see page 1837, Annual Report for 1915. Existing project. This provides for a dredged channel 2,200 feet long, 150 feet wide, and 51/ feet deep at mean low water through the bar at the mouth of the river, and a navigable chan- nel from the mouth to Patsaliga Creek, 147 miles. The channel above the mouth of the river was to be obtained by removing cer- tain obstructions to navigation and by constructing dikes, wing dams, and shore protection to obtain 5 feet to the Florida State line. A navigable channel in the Conecuh River was to be obtained by removing snags, closing cut-offs, and constructing wing dams. Dikes and wing dams are of the usual pile-and-brush type. The mean range of tide at the mouth of the river is 1.5 feet and the extreme range, except during storms, 3 feet. At the Florida State line the ordinary seasonal fluctuation of stage does not exceed 8 feet. The highest flood stage attained in the record flood of 1929 was 31.3 feet above low water at the Florida State line and 50.6 feet at River Falls, Ala., 144 miles above the mouth. The cost for new work, for the completed project exclusive of the amount expended on previous projects, was $47,161. The latest (1951) approved estimate of annual cost of maintenance is $1,500. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents June 14, 1880 A channel through the bar at the mouth of the river Annual Report 1879, p. 852. and to the Florida State line.

ALABAMA-COOSA RIVERS, ALA. AND GA. Location. The Alabama River is formed 18 miles above Mont- gomery, Ala., by the junction of the Coosa and Tallapoosa Rivers. Thence it flows southwesterly through Alabama 318 miles, and unites with the Tombigbee River about 45 miles north of Mobile, in southwestern Alabama, to form the Mobile River. (See U. S. Geological Survey maps for central and southwest Alabama.) The Coosa River is formed at Rome, Ga., in northwest Georgia, by the junction of the Oostanaula and Etowah Rivers, which have their sources in northern Georgia. From Rome the Coosa River flows southwesterly through Georgia and Alabama 286 miles and unites with the Tallapoosa River near Montgomery, Ala., at about the center of the State, to form the Alabama River. (See U. S. Geological Survey maps for northeast Alabama and northwest Georgia.) Previous projects. Previous projects for Alabama River were adopted by the River and Harbor Acts of June 18, 1878, July 13, 1892, March 3, 1905, and June 25, 1910. For further details see page 1837, Annual Report for 1915, page 725, Annual Report for 1938, and paragraph "Existing project," page 592, Annual Re- port for 1944. RIVERS AND HARBORS--MOBILE, ALA., DISTRICT 717 Previous projects for the Coosa River were adopted by the River and Harbor Acts of August 14, 1876, September 18, 1890, July 13, 1892, June 25, 1910, and June 26, 1934. For further details of previous projects see page 1837, Annual Report for 1915, page 728, Annual Report for 1938, and paragraph "Exist- ing project," page 594, Annual Report for 1944. Existing project. This provides for the initial and ultimate development of the Alabama-Coosa Rivers and tributaries for navigation, flood control, power, and other purposes, substantially in accordance with plans being prepared by the Chief of Engi- neers with such modifications thereof from time to time as in the discretion of the Secretary of War and the Chief of Engineers may be advisable for the purpose of increasing the development of hydroelectric power; for the initiation and accomplishment of the ultimate plan, it authorizes appropriations in such amounts as Congress may from time to time determine to be advisable, the total of such appropriations not to exceed $60,000,000. The initial phase of the ultimate development provides for the construction of Howell Mill Shoals, Jones Bluff, and Millers Ferry multiple-purpose improvements, Claiborne lock and dam, and supplemental channel work to provide a channel depth of 9 feet for navigation from the mouth of the Alabama River to Mont- gomery, Ala. The variation between average high and low water is 40.4 feet. The extreme variation is 58 feet, at Montgomery.

ARMY, 1951 The existing project was adopted by the River and Harbor Act of March 2, 1945 (H. Doc. 414, 77th Cong., 1st sess.). The latest published map of Alabama River will be found in Annual Report, 1912, page 2124. Drawings of the Alabama-Coosa Rivers and tributaries are contained in House Document No. 66, Seventy- fourth Congress, first session. The latest published maps of the Coosa River will be found in Annual Report, 1890, page 1644, for that portion of the river from lock No. 4 to Greensport; Annual Report, 1891, page 1752, for that portion between Wetumpka and lock No. 4; and Annual Report, 1913, page 2125, for the upper Coosa. Local cooperation. None required. Terminal facilities. On the east bank at Montgomery, a nat- ural landing connects with the city streets. The Wofford Oil Co. has a small wharf about 10 miles below Montgomery equipped for handling petroleum products. There are also various natural land- ings along the river. These facilities and natural landings on the Alabama River are considered adequate for the existing com- merce. At Rome, Ga., there is one small wharf on the left bank of Oostanaula River, and a private wharf on the left bank of Eto- wah River, used exclusively by the owners. These facilities and natural landings on the Coosa River are considered adequate for the existing commerce. Operations and results during fiscal year. New work: Work on engineering studies and advance planning was continued at a cost of $193,960.47. The expenditures were $191,050.44. Condition at end of fiscal year. No construction has been performed on the existing project. The controlling depths on the Alabama River, ascertained in 1938, were as follows: Mouth to Selma, 4 feet; Selma to Montgomery, 3.5 feet; Montgomery to Wetumpka, 3 feet. Boats drawing 3 feet or less can usually operate throughout the year; greater depths are usually available from November to June each year. Zero readings on the gages at Selma and Millers Ferry, Ala., indicate that a depth of 4 feet is avail- able at these locations. A zero reading on the gage at Montgomery, Ala., indicates that a depth of 31/2 feet is available. On the Coosa River the controlling depth was 21/2 feet on several of the bars; from Gadsden, Ala., to Woods Ferry, 37 miles, the controlling depth was 3 feet, certain shoals being the controlling points. From Woods Ferry to Lock No. 4, 9 miles, the controlling depth was 4 feet. These depths are available throughout the year; increased depths ordinarily exist between January and June, inclusive. Since all existing locks on this river are inoperative, through navigation is impossible.

BLACK WARRIOR, WARRIOR, AND TOMBIGBEE RIVERS, ALA. Location. The Black Warrior and Warrior Rivers, a single stream, rise in northern Alabama above Birmingham and flow generally southwesterly to unite with the Tombigbee River at Demopolis, Ala. Thence, the Tombigbee flows south, uniting with the Alabama River to form the Mobile River 45 miles above the head of Mobile Bay. The distance by water from Mobile to the vicinity of Birmingham is about 415 miles. Previous projects. The original project for the improvement of Warrior River, now combined with the Black Warrior and Tombigbee Rivers, was adopted by act of March 3, 1875. For further details see page 1841, Annual Report for 1915, and page 732, Annual Report for 1938. Existing project. This provides essentially for a canalized channel with minimum depth of 9 feet and a width of 200 feet, where practicable, from the mouth of the Tombigbee River, 45 miles above Mobile, to the vicinity of Birmingham, via the Tom- 720 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 bigbee and Warrior Rivers, to mile 447.6 on Sipsey Fork, mile 444.6 on Mulberry Fork, and mile 420.6 on Locust Fork, a total distance of 426.6 miles. The lift is accomplished by 15 locks and dams, one of the locks being a double-lift structure. The project also provides for construction of a new lock and dam near Demopolis, Ala., to replace existing dams 4, 5, 6, and 7, and for increasing the length of the spillway at dam 1. The proj- ect also provides for operation and care of all locks and dams.

S. ARMY, 1951 Tidal influence extends from Mobile 101.6 miles to lock 1, where the tidal effect is apparent only at low stages of river. At Mobile the mean and extreme tidal ranges are 1.5 and 3.6 feet, respec- tively. These are at times slightly increased by the effect of winds. The greatest fluctuation of river stages is at Demopolis, Ala., the maximum being 59.7 feet. The maximum fluctuations at other points are 40 feet at lock 1, 101.6 miles from Mobile; 57.8 feet at Tuscaloosa, Ala., 352.6 miles from Mobile; 13 feet at Birmingport, 409.6 miles from Mobile; and 27 feet at Cordova, 429.6 miles from Mobile. The ordinary fluctuations at these points are at lock 1, 20 feet; at Demopolis, 35 feet; at Tuscaloosa, 40 feet; at Birming- port, 4 feet; and at Cordova, 7 feet. The works of improvement have reduced the amount of fluctuations at different points by 3 to 10 feet. The estimated cost of new work, approved in 1951, is $37,468,- 000. The latest (1951) approved estimate for annual cost of maintenance is $750,000, including $350,000 for operating and care.

WATERWAY CONNECTING THE TOMBIGBEE AND TENNESSEE * RIVERS, ALA. AND MISS. Location. From mile 215 on the Tennessee River, this water- way extends southerly through eastern Mississippi 154 miles and western Alabama 106 miles, a total of 260 miles, to the confluence of the Warrior and Tombigbee Rivers at Demopolis, Ala. Previous projects. Work between Demopolis and Columbus was commenced in 1871 and modified in 1879. For the section above Columbus there are no previous projects. The total cost and expenditure on the section between Demopolis and Columbus was $63,382.98, of which $47,342.98 was for new work and $16,040 for maintenance. For further details see page 1842, Annual Report for 1915. The act of September 19, 1890, provided for improvement and maintenance of the section between Columbus and Demopolis (H. Doc. 156, 51st Cong., 1st sess., and Annual Report for 1890, p. 1719); the acts of March 3, 1873, and August 11, 1888, pro- vided for improvement and maintenance of that part of the waterway between Columbus and Walkers Bridge (Annual Re- ports for 1873, p. 548, and 1882, p. 1312); the act of February 27, 1911, consolidated the improvement from Demopolis to Walk- ers Bridge under one head and made one appropriation for that section. The River and Harbor Act of August 30, 1935, provided for abandonment of the project for the slack-water improvement of the Tombigbee River above Demopolis (H. Doc. 56, 73d Cong., 1st sess.). For further details see page 699, Annual Report for 1937. The total cost under the previous project was $431,981.44, of which $197,650.71 was for new work and $234,330.73 for maintenance. Existing project. This provides for a waterway to connect the Tombigbee and Tennessee Rivers by way of the East Fork of the Tombigbee River, Mackeys and Yellow Creeks, to provide a chan- nel from the junction of the Tombigbee and Warrior Rivers at RIVERS AND HARBORS-MOBILE, ALA., DISTRICT 727 Demopolis, Ala., for 260 miles to the Pickwick Pool on the Ten- nessee River, not less than 9 feet deep with a minimum bottom width of 170 feet in the river and canal section and 150 feet in the divide cut, with locks 110 by 600 feet clear inside dimensions. 'The plan of improvement for the waterway may be divided into three sections as follows: River section from the junction of the Warrior and Tombigbee Rivers at Demopolis, Ala., to mile 180 on the Tombigbee River, with a channel 9 feet deep and 170 feet wide, to be obtained by dredging and construction of 4 locks and dams; the canal section from mile 180 to mile 221, with a channel 12 feet deep and 170 feet wide, to be obtained partly by excavation and partly by levees, and by the construction of 6 locks; the divide section from mile 221 to mile 260 in the Pick- wick Pool on the Tennessee River, with a channel 12 feet deep and 150 feet wide, by means of a lock and dam at the Narrows and a 27-mile cut. Passing places 200 feet wide and 1,000 feet long, with transitions 500 feet long at each end, are to be pro- vided about every 4 miles in the divide section.

(See H. Doc. 408, 75th Cong., 2d sess.) Terminal Facilities. A privately owned wharf at the Pearl River highway bridge near Pearl River Station, La., is used for unloading logs. No other facilities exist except natural landings at various locations on the river. These facilities are considered adequate for existing commerce. Operations and results during fiscal year. New work: The final cost on locks 2 and 3 was $23,801.87. Grassing, sodding, and sprigging esplanades, levees, and vicinities at locks 1, 2, and 3 cost $4,529.58. Repairs to the construction office at lock 2 cost $792.96. Surveys, plans and specifications cost $1,618.24. Maintenance: Miscellaneous investigations and surveys cost $789.47. Operating and care: Ordinary maintenance and repair of the three locks cost $7,835.49. The total cost was $44,009.14, including $4,641.53 transferred to operating and care from fiscal year 1950 deferred account, of which $30,742.65 was for new work, $789.47 for maintenance, and $12,477.02 for operating and care. The expenditures were $126,040.44. Condition at end of fiscal year. The existing project, com- menced in October 1938, was about 90 percent completed. Lock 1 was completed in February 1949, lock 2 in June 1950, and lock 3 in May 1950. The controlling depth for all-year navigation at the end of the fiscal year was 4 feet from mile 0 to the site of lock 1 (about 30 miles). During the low-water season, June 742 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 through December each year, a depth of 1.5 feet is available along the natural channel between the mouth of Holmes Bayou and Bogalusa, the present head of navigation. A minimum depth of 6 feet is usually available over that stretch of the river from January 1 to June 1 each year; however, navigation is now impracticable due to numerous logs, stumps, and other obstructions. The work remaining to be done to complete the project consists of construction of Bogue Chitto and Pools Bluff sills; clearing the low-water pools of locks 1 and 2; and dredging and snagging the channel of Pearl River between Pools Bluff and Bogalusa. The cost of the existing project to June 30, 1951, was $7,- 305,364.16, of which $7,292,097.67 was for new work, $789.47 for maintenance, and $12,477.02 for operating and care.

RED RIVER BELOW FULTON, ARK. Location. Red River rises in the arid regions of eastern New Mexico, flows in a general easterly and southeasterly direction RIVERS AND HARBORS--NEW ORLEANS, LA., DISTRICT 759 for 1,300 miles, and enters the Mississippi River at Red River Landing, La. (See U. S. Geological Survey State maps and Mississippi River Commission alluvial valley quadrangle maps.) Previous projects. Authorized by River and Harbor Acts of May 23, 1828; June 10, 1872; June 18, 1878; March 3, 1879; August 2, 1882; July 5, 1884; August 11, 1888; and September 19, 1890. For further details, see page 1868 of Annual Report for 1915 and page 895 of Annual Report for 1938. Existing project. This provides for continuing improvement of Red River from Fulton, Ark., to the Atchafalaya River, La., 455.6 miles by systematic clearing of the banks, snagging, dredg- ing shoals, building levees (either alone or in cooperation with riparian States), closing outlets, revetting caving banks, and preventing injurious cut-offs. The lower end of the section in- cluded in the project is 7.6 miles above the mouth of the river. No proposed channel dimensions are given. Floods ordinarily cause fluctuations of stage between high and low water of from 30 to 45 feet. Unusual floods occasionally increase this range about 10 feet. The flood of March-April 1945 produced crest stages 1 to 3 feet higher than maximum previously recorded. As the work is continuing, no estimate for completion was made. The latest (1941) approved estimate for annual cost of maintenance is $27,000. The existing project was authorized by the River and Harbor Act of July 13, 1892 (Annual Reports for 1890, p. 1829, and for 1891, p. 1957), and modified by the River and Harbor Acts of July 24, 1946, and May 17, 1950, to authorize construction of the Overton-Red River waterway to Shreveport, La., and pro- vide a channel 9 feet deep and 100 feet wide from the Mississippi River to the north bank of Black River (mile 35.5). (For latest published maps see H. Doc. No. 378, 74th Cong., 2d sess.) Terminal facilities. None. Operations and results during fiscal year. None by the New Orleans district, CE. The dredge Vicksburg under contract with the Vicksburg district, CE, and with funds transferred to that district by the New Orleans district in the previous fiscal year for the purpose, removed approximately 134,671 cubic yards from Red River in the vicinity of Kings Bayou, approximately mile 34 above mouth of Red River, during the period September 10 and 24, 1950. This work was accomplished in connection with contract dredging accomplished by the Vicksburg on Black and Ouachita Rivers for the Vicksburg district. Condition at end of fiscal year. Maintenance in recent years provides for navigation to Shreveport, La., at medium and high stages. The head of navigation is the Arkansas-Oklahoma State line, to which point boats may occasionally run during high water if snags, overhanging trees, or similar obstructions do not inter- fere. From January to July the prevailing stage is 6 feet and over, and minimum depths are about 4 feet to Fulton, 5 feet to Shreveport, and 6 feet to Alexandria. During the remainder of the year stages near zero may be expected, with minimum 760 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 depths less than 1 foot from Fulton to Shreveport, 1 to 2 feet from Shreveport to Alexandria, 4 feet from Alexandria to mouth of Black River, and 6.5 feet thence to mouth. Project depth obtained at the end of the fiscal year. Total costs and expenditures under the existing project to June 30, 1951, were $409,928.91 for new work and $1,775,680.17 for maintenance, a total of $2,185,609.08. Proposed operations. No work is scheduled by this district for the fiscal year 1952; however, the Vicksburg district, CE, will complete the dredging of Red River in vicinity of Kings Bayou, approximately mile 34 above mouth of Red River, with the U. S. dredge Todd. This will complete all work scheduled to be accomplished with funds transferred during the fiscal year 1950. The sum of $35,000 can be profitably expended for the fiscal year 1953 for dredging in Red River between the mouth of the Black River and the Mississippi River.

OVERTON-RED RIVER WATERWAY, LA. Location. The work covered by this improvement is located in the State of Louisiana between the junction of the Old and Mississippi Rivers and Shreveport, La., along the Old and Red Rivers, through land cuts and natural channels on the south bank of Red River. (See U. S. Geological Survey State maps and Mississippi River Commission alluvial valley quadrangle maps.) Existing project. This improvement provides for a channel 206 miles long, 9 feet deep, and 100 feet wide, extending from the Mississippi River at mile 301 above the Head of Passes through Old River and Red River to mile 31, thence by a lateral canal extending through land cuts and existing waterways, across the Mississippi-Red River backwater area and along the south bank of Red River floodplain to Shreveport, La. The project includes the construction of nine locks, and a pumping plant on Red River near Shreveport. Floods ordinarily cause fluctuations of stage between high and low water in Old River, Red River, and the backwater area of from 30 to 45 feet; the fluctuation of stages on the south bank tributary streams are somewhat less. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 761 The latest (1951) approved estimated cost is $75,000,000 for construction and $700,000 for maintenance, of which $600,000 is for operation and care and $100,000 is for channel mainte- nance. This improvement in the existing project was authorized by the River and Harbor Act approved July 24, 1946 (H. Doc. 320, 80th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Local interests are required to furnish free of cost to the United States all lands, easements, rights-of- way, and spoil disposal areas for new work and subsequent main- tenance when and as required; make all necessary changes in existing highways, highway bridges, and approaches thereto, and all necessary changes in public utilities, except railroad facilities; maintain parts of all railroads, highways, bridges, and utilities affected by the improvement; establish, maintain, and operate adequate terminal and transfer facilities; and hold and save the United States free from damages incident to construc- tion, maintenance, and operation of the improvement. Preliminary negotiations have been conducted with the De- partment of Public Works, State of Louisiana, to determine proper agencies to furnish required local cooperation. Requests for assurances of local cooperation have not yet been made. Terminal facilities. None. Operations and results during fiscal year. Hydraulic, hydro- graphic, and other studies, field surveys and investigations for advance planning, and soil borings for channel excavation, were carried on by hired labor at a cost of $44,156.34 for new work; expenditures were $44,218.15. Condition at end of fiscal year. Only preliminary work has been done to date. The total costs under the project to the end of the fiscal year were $175,746, new work; expenditures were $176,126.71. Proposed operations. The balance unexpended at the end of fiscal year, $28,873.29, plus accounts receivable, $402.22, a total of $29,275.51, will be applied as follows: New work: Accounts payable, June 30, 1951 ......................... $21.51 Advance planning, surveys, soil borings, hydraulic studies, and mapping ....................................... 29,254.00 Total ................................ .... .. ......... 29,275.51 The additional sum of $1,000,000 can be profitably expended for the following scheduled work during the fiscal year 1953: New work: By contract: Channel excavation, mile 96 to mile 110...... $800,000 By hired labor: Surveys, investigations, designs, and plans and specifications .................................... 200,000 Total for all work ............................ 1,000,000 762 REPORT OF CHIEF OF ENGINEERS, U.

This bayou rises in northeast Texas and flows in a southeasterly direction to Caddo Lake, through this lake to Big Willow Pass, and through Big and Little Willow Passes, Soda Lake, Twelve Mile Bayou, the new diversion canal, and Cross Bayou to the Red River at Shreveport, La., a distance of about 132 miles. (See U. S. Geological Survey State maps.) Cypress Bayou proper ends where it enters Caddo Lake, but the name is frequently applied to the whole waterway above described. Existing project. This provides for dredging and straighten- ing the channel, removing obstructions, and clearing the banks for 66 miles from Red River at Shreveport, to Jefferson, and for the construction of a dam without a lock at the foot of Caddo Lake. Caddo Lake Dam Location ...................... At foot of Caddo Lake, La., and Tex., about 23 miles above mouth of Jeffer- son-Shreveport waterway. Below Mooringsport, La........ . 2 miles. Length ....................... 3,400 feet. Type ........................ Fixed, on pile foundation. Date of completion ............ Dec. 21, 1914. Cost .......................... $100,553.47. Below the dam, fluctuations of water level depend chiefly upon backwater from Red River, the maximum being about 10 feet. At the dam, fluctuations are from 2.5 feet below to 13.3 feet above the crest of the spillway, and at Jefferson the maximum was 30.4 feet. The project was completed at a cost of $202,818. The latest (1950) approved estimate for annual cost of maintenance is $5,200, including $3,500 for operating and care.

The following terminal. facilities are located at Mooringsport, La.: One privately owned covered dock, 60 by 60 feet, open to all small boats One privately owned pipe rack, not decked One privately owned boat ways The warehouse at Jefferson has not been used for several years, since no commerce has moved in that vicinity. The wharf, dock, pipe rack, and boat ways at Mooringsport are all owned by oil companies. There are no terminal facilities at Shreveport. The existing terminal facilities are considered adequate for present commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. The dam at the foot of Caddo Lake was completed in 1914, completing the project. Its construc- tion and maintenance insure a 4-foot navigable depth at low water from that point to Jefferson, the head of navigation, but prevent possible navigation to Shreveport, except for such light draft boats as may pass over the dam at high stages. Below the dam, navigation is largely dependent upon backwater from Red River. A stage of from 15 to 24 feet on the Red River gage at Shreveport, depending on the run-off from Cypress Bayou drain- age area, is necessary to provide a 4-foot depth up to the dam. Such stages are short in duration and irregular in occurrence. The total costs and expenditures to the end of the fiscal year were as follows: United States Contributed funds funds Total ..

GULF INTRACOASTAL WATERWAY BETWEEN APALACHEE BAY, FLA., AND THE MEXICAN BORDER (NEW ORLEANS DISTRICT) Location. The section of the Gulf Intracoastal Waterway within the New Orleans District extends from Lake Borgne Light No. 41, near the mouth of the Rigolets, to the Sabine River, La., and Tex. The section from Lake Borgne Light No. 41 to the Mississippi River follows the Rigolets and Lake Pontchartrain to the lake end of the State-owned Inner Harbor Navigation Canal, thence by way of this canal to the Mississippi River, a distance of 40.5 miles. By Public Law No. 675, Seventy-seventh Congress, ap- proved July 23 1942, the project was modified to provide for a land cut through the marsh from the Rigolets to a point on the Inner Harbor Navigation Canal about 2.25 miles from the Mississippi River, eliminating passage through Lake Pontchar- train and five drawbridges, a distance of 30.8 miles to the Mis- sissippi River by this route. From the Inner Harbor Naviga- tion Canal to the entrance to Harvey lock, the route follows the Mississippi River for a distance of 5.5 miles. The section from the Mississippi River to Atchafalaya River, La., leaves the Mississippi River through Harvey lock about 3.3 miles above Canal Street and follows Harvey Canal No. 1 and Bayou Barataria to Bayou Villars, a land cut south of Lake Sal- vador to Harvey Canal No. 2, Harvey Canal No. 2 to Larose, La., and a land cut to Houma, La., thence over a land cut south of Bayou Black and Bayou Cocodrie, thence through Bayou Cocodrie and a land cut to Bayou Black; thence through Bayou Black, Bayou Chene, and Bayou Boeuf to the Atchafalaya River, about 0.5 mile south of Morgan City, La., a total distance of 95.5 miles. An alternate connection with the Mississippi River in the vicinity of Algiers, La., about 10.3 miles below Harvey lock, con- sisting of a lock and land cut about 9 miles in length intersecting the Intracoastal Waterway at about mile 6, is now under con- struction. An alternate route from the Mississippi River at Plaquemine, La. (113 miles above New Orleans), follows Bayou Plaquemine RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 765 and lower Grand River to and through a lock now under construc- tion at Bayou Sorrel in the East Atchafalaya Basin protection levee, thence through the levee borrow pit to Berwick Bay; and thence through Berwick Bay to Morgan City, La., a total distance of 56 miles. This alternate route is to be enlarged from the vicinity of Morgan City to Indian Village, La., and to be extended from Indian Village, La., through Bayou Grosse Tete and a new land cut to and through a new terminal lock and entrance channel to the Mississippi River in the vicinity of Port Allen, La., a distance of 65 miles. The section from the Atchafalaya River to Vermilion River, La., begins at the western end of the Mississippi-Atchafalaya section and follows the Atchafalaya River about 2.5 miles, por- tions of Little Wax Bayou, Possum Bayou, cut-offs, a land cut passing through North Bend Plantation to Bayou Bartholomew; Bayou Bartholomew to Little Bay, a land cut skirting the north edge of Cote Blanche Island and the west edge of Weeks Island to Vermilion River, about 24 miles below Abbeville, La., a total distance of about 63.6 miles. Franklin Canal, St. Mary Parish, La., extends southwesterly from Franklin, La., on Bayou Teche, for 5.15 miles to Bayou Portage, a section of "The Inland Waterway from Franklin to the Mermentau River, La.," and through the bayou for 0.75 mile to the Gulf Intracoastal Waterway, 121 miles west of Harvey lock. The section from Vermilion River to Mermentau River, La., begins at the western end of the Atchafalaya-Vermilion section and follows Vermilion River 1.3 miles, a part of the Schooner Bayou cut-off canal, and a land cut running in a general north- westerly direction to Mermentau River at a point about 0.5 mile above its entrance into Grand Lake and about 16 miles below the town of Lake Arthur, La., a total distance of about 42.7 miles. Vermilion lock has been constructed about 1.75 miles west of Vermilion River to prevent the ingress of salt water from Ver- milion Bay. The section from Mermentau River to Calcasieu River, La., begins at the western end of the Vermilion-Mermentau section and follows the Mermentau River upstream for about 1.5 miles, a land cut running in a west-southwesterly direction to Lake Misere, passing north of the lake and Bayou Misere, westerly to Sweet Lake, south and west of Sweet Lake, northwesterly to Bayou Tete Bois, through Bayou Tete Bois, Black Bayou, and cut-offs to a point on Calcasieu River about 16.6 miles below the city of Lake Charles, La., a total distance of about 37.1 miles. A salt-water guardlock in the waterway at mile 238 west of Harvey lock is now under construction. The section from the Calcasieu River to Sabine River, La., and Tex., begins at the western end of the Mermentau-Calcasieu sec- tion, and follows the Calcasieu River upstream about 1.6 miles, a land cut running in a southwesterly direction 2.8 miles, thence west 22 miles to Sabine River at a point about 3 miles below Orange, Tex., a total distance of about 27.1 miles. 766 REPORT OF CHIEF OF ENGINEERS, U.

Vermilion lock was completed in 1934; the ground on which it is constructed is possessed by the United RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 773 States under an easement deed to a strip of land 300 feet wide along the Intracoastal Waterway. Bayou Sorrel lock was com- pleted in 1951; the reservation comprises 262.1 acres. Dredging of the canal, except for the work authorized under River and Harbor Acts of March 2, 1945, and July 24, 1946, was commenced on December 19, 1942, and completed on June 9, 1944. Inner Harbor Navigation Canal lock was leased by the United States from the Board of Commissioners of the Port of New Orleans, effective April 1, 1944. Dredging Franklin Canal to an interim 8- by 50-foot section was completed during the period July 26, 1949, and March 14, 1950. The alternate connection below Algiers, with new lock, is ap- proximately 28 percent complete, with the following work having been accomplished to date: Excavation of lock site, driving of all foundation piling and steel sheet piling, placing of reinforced con- crete floor, and erection of lock walls. Construction of backfill for the lock, guide levees for the river approach channel to the lock, and emergency dam storage, is in progress. Sector gates have been fabricated and are being erected, and excavation of a section of the navigation canal in Orleans Parish, and planning for the construction of two vertical lift bridges, under continuing contract, are in progress, as is engineering service contract for design plans and specifications of drainage pumping station. Contracts for constructing guide walls, and furnishing and in- stalling the operating machinery and electrical system were awarded in June 1951, but no work has been done to date. Calcasieu lock is approximately 99 percent complete, with the construction of gate bays, earthwork, timber guide walls, approach channels and dam embankment, sector gates, installa- tion of operating machinery and electrical system, storage of needle dams, fencing and seeding of reservation, and construc- tion of 15-foot shell surface access road to Calcasieu lock com- plete. The lock was opened to navigation on December 18, 1950. Bayou Sorrel lock, constructed with funds for Flood Control, Mississippi River and tributaries, and located in the East Atcha- falaya Basin protection levee, was completed and opened to navigation on June 4, 1951, and has been incorporated as part of the Gulf Intracoastal Waterway alternate route from Port Allen, La., to Morgan City, La. New work remaining to complete the project, besides that which is now in progress and/or under contract, consists of: Alternate connection below Algiers with new lock: Construction of a vertical lift railroad bridge for the New Orleans and Lower Coast Railroad crossing; relocation of railroads and utilities; drainage canal excavation for restoration of drainage, including the construction of two pumping stations, construction of that section of the navigation canal in Plaquemines Parish, and com- pletion of the section in Orleans Parish. Calcasieu lock: Installa- tion of utilities and building of access roads.

THE INLAND WATERWAY FROM FRANKLIN TO THE MERMENTAU RIVER, LA. Location. This canal extends from Hanson lock on Bayou Teche through Hanson Canal and Bayou Portage to the Intra- coastal Waterway, and along the Intracoastal Waterway to mile 161, west of Vermilion Bay. The total length of the waterway is 26.8 miles. (See U. S. Coast and Geodetic Survey Chart No. 1116; RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 779 Corps of Engineers, Mississippi River Commission alluvial valley map, and Foster, Bayou Sale, Jeanerette, and Derouen quad- rangles; U. S. Geological Survey maps, Abbeville (southeast), and Abbeville (southwest).) Existing project. This project, as modified by the River and Harbor Act approved July 24, 1946 (S. Doc. 231, 79th Cong., 2d sess.), provides for a waterway from Bayou Teche at or near Franklin, La., to the western end of Vermilion Bay, having a depth of 5 feet below mean low Gulf and a bottom width of 40 feet, with appropriate side slopes; also the purchase of the Hanson Canal. This project, reported in the Annual Report for 1924 under the headings, Intracoastal Waterway, Franklin to Mermentau, La., and Intracoastal Waterway from Vermilion River to Schooner Bayou, La., has largely been superseded by the project "Gulf In- tracoastal Waterway (New Orleans District)." The River and Harbor Act approved July 24, 1946 (S. Doc. 231, 79th Cong., 2d sess.), authorized the incorporation of the existing project "In- land Waterway from Franklin, La., to the Mermentau River," west of Vermilion Bay, in the modified Flood Control, General, project "Mermentau River, La." Under ordinary conditions the mean range of tides is about 10 inches and the extreme range about 14 inches. A severe storm may cause a high tide of from 6 to 9 feet. The cost for new work to June 30, 1951, was $249,052. The latest (1950) approved estimate for annual cost of maintenance is $22,000, including $12,000 for operation and care of Hanson lock. Data regarding the lock are as follows: Hanson lock Miles from Franklin, La. .................. 1.5. Miles from Bayou Teche .................. 0. Width of chamber ........................ 26.5 feet.

Operations and results during fiscal year. Hanson lock was operated, as required, throughout the fiscal year; the lock, structures, and grounds were maintained in good condition, and all necessary and routine maintenance work thereon performed at a cost of $4,647.04, operating and care; expenditures were $4,554.38. Condition at end of fiscal year. The project was considered complete prior to the modification by the River and Harbor Act approved July 24, 1946, which provided for channel enlargement and realignment from Vermilion Bay to White Lake and from White Lake to Grand Lake; for channel enlargement of North Prong of Schooner Bayou and for construction of a gated control structure in the new channel near Schooner Bayou lock, and the incorporation of the existing project "Inland Waterway from Franklin to the Mermentau River, La.," west of Vermilion Bay, in the modified Flood Control, General, project "Mermentau River, La." The Hanson Canal and lock were acquired on October 16, 1923; the lockmaster's house was completed in 1924; the United States property on which the lock is situated is a strip of land 300 feet wide between parallel lines running from Bayou Teche to Bayou Portage, containing 148 acres. Dredging from Vermilion Bay to the Mermentau River was completed in 1912. The channel is navigable throughout its length, with controlling depth (May 1950) of 2.5 feet, mean low Gulf, from Franklin, La., to Gulf Intracoastal Waterway, via Hanson Canal and Bayou Portage. The total costs to the end of the fiscal year were $781,526.22, of which $249,051.81 was for new work, $137,262.45 for mainte- nance, and $399,859 was for operating and care; expenditures were $786,226.10. Proposed operations. The balance unexpended at the end of the fiscal year, $4,794.62, plus accounts receivable, $52.84, and an allotment of $3,000, a total of $7,847.46, will be applied to maintenance of Hanson lock. The sum of $3,400 is needed to be appropriated during the fiscal year 1953 for maintenance of Hanson lock.

BAYOUS LA LOUTRE, ST. MALO, AND YSCLOSKEY, LA. Location. From their common head at the small settlement of Yscloskey, Bayou La Loutre flows southeasterly for 29.4 miles to Eloi Bay, and Bayou Yscloskey northeasterly for 2.2 miles to Lake Borgne. Bayou St. Malo leaves Bayou La Loutre at mile 19.4 flowing northwesterly 6.5 miles to Lake Borgne. (See U. S. Coast and Geodetic Survey Charts Nos. 1270 and 1271, and U. S. Geological Survey maps, Shell Beach, Lake Eloi, Lake Eugenie, and Morgan Harbor quadrangles.) Existing project. This provides for a channel 5 feet deep and 40 feet wide from deep water in Lake Borgne to the shore line at the mouth of Bayou Yscloskey; a channel 6 feet deep and 40 feet wide from deep water in Lake Borgne through Bayous St. Malo, La Loutre, and Eloi to deep water in Lake Eloi; and a channel 5 feet deep and 30 feet wide in Bayou La Loutre between Hopedale and Bayou St. Malo, the total length of the improvements being 30.0 miles. The normal tidal variation is about 1 foot. Hurricane tides, 6 feet above normal, have been reported. The estimated cost of new work, made in 1951, is $96,800. The latest (1950) approved estimate for annual cost of maintenance is $12,000. The existing project was adopted by the River and Harbor Act of August 26, 1937 (H. Doc. 275, 75th Cong., 1st sess.), and modi- fied by the River and Harbor Act of March 2, 1945 (S. Doc. 116, 77th Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Fully complied with, except for modifica- tion of 1945; request for compliance not yet made. Operationsand results during fiscal year. Cost of preliminary surveys, plans, and specifications for maintenance dredging in bar channels of Bayous Yscloskey and St. Malo amounted to $467.86; expenditures were $1,132.39.

The project, prior to the modi- fication adopted by the River and Harbor Act of March 2, 1945, which provided for the dredging of a channel 5 feet deep and 30 feet wide in Bayou La Loutre between Hopedale and Bayou St. Malo, was completed in 1940. 782 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The existing project, as modified, is 45 percent complete. The project will be considered complete when the modification of 1945 is accomplished. The controlling depths, mean low Gulf (May 1951) were: Bayou Yscloskey: Over bar, 1.4 feet; to Yscloskey, La., 2.4 feet. (Entire bar and jetty channel is in need of dredging. At low tide the bar cannot be negotiated.) Bayou La Loutre: Ysclosky, La., to Baker's Canal, 2.1 feet; to Bay Eloi, 4.1 feet; over the bar, 2.6 feet. (Numerous palmetto stumps and roots cover bottom between miles 14.3 and 20.9. Navigation is practically impossible in this area at low tide, except for very small craft.) Bayou St. Malo: Over bar and through bayou, 3.7 feet. Total costs under the existing project to the end of the fiscal year were $99,848.63, of which $43,619.54 was for new work and $56,229.09 for maintenance; expenditures were $99,848.63.

MISSISSIPPI RIVER, BATON ROUGE TO THE GULF OF MEXICO, LA. Location. The Mississippi River between Baton Rouge and the Gulf of Mexico flows in a general southeasterly direction through the southeastern portion of the state of Louisiana. At the Head of Passes, 233.1 miles below the Louisiana Highway Commission bridge at Baton Rouge, the river is broken up into three main passes, Southwest Pass, South Pass, and Pass a Loutre, two of which, Southwest Pass and South Pass, are improved under the existing project. The distances from Head of Passes to the mouths of Southwest and South Passes are 20.1 miles and 13.5 miles, respectively. The mouth of Southwest Pass is 141 miles from Mobile, Ala., on the east, and 349 miles from Galveston, Tex., on the west. The mouth of South Pass is 18.5 miles north- east of the mouth of Southwest Pass. (See U. S.

This provides for channel dimensions as follows: Between a line one-half mile below the Louisiana Highway Commission bridge at Baton Rouge and the upper port limits of New Orleans, 35 feet deep (mean low Gulf) by 500 feet, a dis- tance of 128.6 miles. Within the limits of the port of New Orleans, where that au- thority has jurisdiction over both banks of the river, 35 feet deep (mean low Gulf) and a maximum width of 1,500 feet, measured from a line generally 100 feet from the face of the left-bank wharves, but not closer than 100 feet to wharves on the right bank, a distance of 17.2 miles. From the lower limits of the port of New Orleans to the Head of Passes, 40 feet deep (mean low Gulf) by 1,000 feet wide, a distance of 86.7 miles. Southwest Pass from Head of Passes to the outer ends of the jetties, 40 feet deep (mean low Gulf) by 800 feet wide, a distance of 21.2 miles. Southwest Pass bar, 40 feet deep (mean low Gulf) by 600 feet "wide. South Pass from Head of Passes to the outer ends of the jetties, 30 feet deep ( mean low Gulf) by 450 feet wide, a distance of 14.2 miles. South Pass bar, 30 feet deep (mean low Gulf) by 600 feet wide. The general plan of improvement of Southwest Pass provides for contracting the pass to a uniform cross section with approxi- mately 1,420-foot surface width by means of jetties, spur dikes: and bulkheads; for channel improvement by dredging and retain- ing the dredged material between the dikes, bulkheads, and jet- ties; for dredging a channel through the outer bar inclining to the left of the jetty axis; for the construction of small revetted openings through the narrow portions of the banks of the pass for purpose of strengthening these banks; for closure of minor out- lets not required for maintenance of the banks; for the construc- tion of sills to prevent the enlargement of the Jump and Cubits Gap; for sill across Pass a Loutre and bank revetment at Head of Passes; as far as Cubits Gap, a distance of 3.5 miles; for repairs to sill across Pass a Loutre and bank revetment at Head of Passes; for construction of dikes with a view to reducing the width of the river above Head of Passes; for the construction of a submerged deflecting dike above the Head of Passes; and for 784 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 other minor work. The east jetty is approximately 24,950 feet in length and the west jetty 19,699 feet. The jetties are composed of a substructure of brush mattresses, originally built to about the elevation of mean low water, surmounted with a superstruc- ture of concrete and large riprap. Spur dikes are composed of cribwork of round piling filled with willows and stone, or with a curtain of round piles along the upstream face. The general plan of improvement of South Pass provides for the construction and maintenance of jetties and spur dikes; main- tenance of a sill across Pass a Loutre; for dredging a channel 35 feet deep and no specified width through the shoals of the river between Cubits Gap and Head of Passes, 31/2 miles, and for sea- ward extension of east jetty at mouth of pass; removal of west dike and construction of spur dikes and bank revetment at Head of Passes removal of false point at the head of South Pass to bottom elevation of minus 45 feet and revetment of new bank line. The east jetty foundation is 12,070 feet long; the inner east jetty is 11,170 feet long; the west jetty is 7,820 feet long; and the inner west jetty is 4,710 feet long. The jetties are composed of a substructure of brush mattresses surmounted by a superstructure of stone and concrete. Spur dikes are composed of a cribwork of round piling filled with willows and stone. The plane of reference is mean low Gulf level. Variation of water surface is 16 inches at the mouths and 10 inches at the heads of the passes, due to tides. The extreme range of tides at the mouths of the passes due to storms is about 28 inches. At New Orleans the extreme range of water surface is about 20 feet due to floods. At Baton Rouge the extreme range is about 45 feet due to floods.

' Authority of Secretary of War, July 22, 1936. SAuthority of Secretary of War, June 30, 1938. The estimate of cost for new work, revised in 1951, is $32,- 047,000. The latest (1950) revised estimate of cost for annual maintenance is $1,750,000. Local cooperation. None required. Terminal facilities. Some 100 piers, wharves, or docks serve the port of New Orleans. Practically all wharves on the east or left bank parallel the river banks forming nearly a continuous covered quay about 10 miles long. A foreign trade zone is located in the port of New Orleans. Public wharves controlled by the Board of Commissioners of the port of New Orleans (the dock board) cover 62 percent of the improved water front. The board also controls the terminal facilities on the Inner Harbor Navigation Canal (the Industrial Canal) which connects the Mississippi River with Lake Pont- chartrain and turning basin (1,000 by 1,000 feet). Since April 1, 1944, the portion of the Inner Harbor Navigation Canal from the Mississippi River to its intersection with the New Orleans- Rigolets section of the Gulf Intracoastal Waterway, exclusive of terminal facilities, but inclusive of the lock and the bridges at St. Claude Avenue and at Florida Avenue, has been under lease to the United States and is now operated by the United States 786 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 on a toll-free basis, 24 hours per day. From the turning basin to the river the canal has a controlling depth of 30 feet. A quay wharf of reinforced concrete, 265 feet wide by 2,400 feet long owned by the dock board is located on the west bank of the canal. All public port facilities are served by paved roadways (gener- ally city streets) and by the Public Belt Railroad, municipally owned and operated, which connects with all 12 trunk lines enter- ing New Orleans. The existing terminal facilities include a ship-side grain eleva- tor, general cargo and cotton wharves, fruit landings, bunkering facilities, terminal warehouses, railroad terminals, marine rail- ways, and drydocks. They are considered adequate for present commerce. (For further details see Port Series No. 20, "The Port of New Orleans, La." 1947.) Modern terminal facilities were installed by the city of Baton Rouge in 1926. A reinforced concrete dock for deep-sea vessels, 308 feet in length, has a covered-shed area of approximately 20,000 square feet and is equipped with a 12-ton locomotive crane. Attached to the downstream end of the wharf is a floating wharf boat 231 by 401/2 feet, of 2,000-ton capacity. The facilities are served by a transfer boat and municipal terminal, having a ca- pacity of 40 cars per day. Private terminals for handling oil and other products are lo- cated at points on both sides of the river between New Orleans and Baton Rouge. The facilities are considered adequate for the existing com- merce, except at Baton Rouge where the demands of present commerce indicate that an extension of the harbor is desirable by an authorized new channel through Devils Swamp, La., as covered in the report of the President, Mississippi River Com- mission. (For further details see "Terminals and Landings on the Inland Waterways of the United States," vol. I, November 1941.) Operations and results during fiscal year. New work per- formed consisted of field investigations, office and engineering studies, and a model pilot study of Southwest Pass channel, all for use in preparing plans and specifications for the improve- ment of the river and passes to obtain project dimensions. The costs were $1,326.84. Maintenance work was as follows: a. Baton Rouge to New Orleans. Maintenance work con- sisted of dredging 831,914 cubic yards of material at Red Eye Crossing, mile 223.5 above Head of Passes, along the alignment of the front and rear range lights for a distance of approximately 6,000 feet. Of this amount, 609,964 cubic yards were removed by hired labor and U. S. dredge Lang fitt and 221,950 cubic yards were removed by the leased dredge Diesel. Maintenance dredging was also performed at Philadelphia Crossing, mile 183 above Head of Passes, for a distance of approximately 5,000 feet by hired labor and U. S. dredge Langfitt removing 551,974 cubic yards of material. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 787 Surveys were made of Red Eye, Medora, Granada, Bayou Goula, Philadelphia Point, and Fairview Crossings, as required.

During the fiscal year under this reciprocal agreement 42,801 cubic yards were removed by leased dredges Tchefuncta and Pontchartrain from within the 100-foot line, and 58,564 cubic yards were re- moved by the Board of Commissioners outside the 100-foot line. River traffic signal lights in the vicinity of Gretna, La., and Governor Nicholls Street in New Orleans, to govern the move- ment of vessels during flood stages on the Mississippi River in the vicinity of Algiers Point, port of New Orleans, were in opera- tion from February 15 to March 26 and from April 9 to 23, 1951. Necessary surveys to determine the condition of the channel in the harbor were made. Costs were as follows: Maintenance by contract: Dredging by leased plant.......... $188,820.67 Maintenance by hired labor: Operation of signal lights ....... 9,039.00 Total ...................................... ...... 197,859.67 c. Southwest Pass. Maintenance work consisted of dredging 936,651 cubic yards of material by U. S. dredge Langfitt at the 788 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Head of Passes for a distance of approximately 2,600 feet along the entrance range into Southwest Pass. At the Southwest Pass Bar and Lower Jetty Channel, mainte- nance work consisted of dredging 5,812,594 cubic yards of ma- terial by U. S. dredge Langfitt between mile 19.5 below Head of Passes and buoy No. 1 on the sea bar, a distance of approximately 7,600 feet. Contract for repairing approximately 2,030 feet of the west jetty, Southwest Pass, with concrete capping, in progress at beginning of fiscal year, was completed on August 8, 1950. Work on contract for repair of 1,670 feet of west jetty and 800 feet of east jetty, Southwest Pass, in force at beginning of fiscal year, was commenced on July 18 and completed on Novem- ber 29, 1950. During the period July 14 and September 28, 1950, the water tower at Burrwood was painted under contract. A continuing contract for capping 11,945 feet of west jetty, Southwest Pass, to complete repair of this jetty and restore it to established grade and section, was entered into on May 21, 1951. At the end of the fiscal year contractor had mobilized and set up a casting plant with work scheduled to commence on July 2, 1951. A new outlet on the west bank of Southwest Pass at mile 11.8 below Head of Passes, was under construction from December 19, 1950, to January 31, 1951, by hired labor forces. Work was commenced on February 1, 1951, by hired labor forces on screening, raising, and repairing the permeable pile dikes in Southwest Pass, at the Head of Passes, and at Pilottown, and at the end of the fiscal year 103,056 linear feet of piling had been driven in completing 21 dikes, and 16 dikes had been wrapped and treated. Tests were made with various erosion resisting lashings to determine best type for wrapping piles. Repair and maintenance of outlets and miscellaneous struc- tures, routine channel surveys, miscellaneous hydraulic investi- gations and examinations and observations were made by hired labor forces. Pilot model study of Southwest Pass was continued. Shore and floating plant and the Burrwood reservation were maintained.

Cost for supervision, inspection, and maintenance of chan- nel patrol from Baton Rouge to the Gulf of Mexico was $15,- 554.00. f. Hydraulic surveys, investigations, and studies continued throughout the fiscal year 1951. Data obtained included com- plete hydrographic surveys of Southwest and South Passes and the river below Wilder Flats, as required; continuous water- level records at controlling points throughout the passes; dis- charge measurements in each of the three main passes; and gagings of minor outlets. Periodic surveys were made of South- west and South Passes, of both bar channels, at the Head of Passes, at Pass a Loutre, Cubits Gap, New Orleans Harbor, and various crossings between Baton Rouge and New Orleans. Average discharge at each of the three main passes of the lower Mississippi River in percentages of the total discharge of the river at the Head of the Passes during the flood cycles are as follows: 1942 1943 1944 1945 1946 1947 1948 1949 1950 1951 Southwest Pass.... 37.20 38.38 38. 15 34. 25 34. 28 38. 15 34. 96 36. 07 36. 24 35. 00 South Pass- _ 17. 04 17. 28 17. 39 18. 41 17. 36 18.37 18.46 17. 43 18.30 20. 28 Pass a Loutre..... 45. 76 44.35 44. 46 47.34 48. 36 43.48 46. 58 46. 50 45. 46 44. 72 Total_--...-. 100. 00 100. 00 100.00 100. 00 100. 00 100. 00 100. 00 100. 00 100. 00 100.

Condition at end of fiscal year. The project as a whole is 79 percent complete. a. Baton Rouge to New Orleans and New Orleans Harbor. This portion of the project was completed in 1940 and mainte- nance dredging is required at the river crossings in the reach above New Orleans and in the New Orleans Harbor. Minor de- ficiences in project depths at the lower end of Dumaine Street and Governor Nicholls Street wharves in the New Orleans Harbor were not corrected because of the presence of revetment mat- tresses at these points. Existing depths at these locations are considered adequate for present and anticipated future com- merce. A natural channel of project dimensions or greater was available throughout the remainder of the project. 790 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The normal width of channel between 35-foot contours within the limits of the port of New Orleans varies from 1,600 to 2,400 feet. Thalweg depths exceed 100 feet. High water shoaling occurs at various points along the east side of the channel in the New Orleans Harbor and dredging is required to maintain project depths to the wharves as the river falls to lower stage. b. Southwest Pass. Construction of contracting dikes and deepening of the pass and bar channel from 35 to 40 feet, mean low Gulf, is yet to be performed. The east jetty has been restored to effective grade and section except for the root section and short areas of recent settlement. Stone is scheduled to be placed during fiscal year 1953 in these settlement areas. This work will complete restoration of the active portion of east jetty. Observations will be made to deter- mine the status of accretions or scour at the root of the east jetty. The west jetty was restored to effective grade and section for a distance of 2,030 feet during fiscal year 1951 using concrete capping. At the end of the year a continuing contract was in effect for capping an additional 11,945 feet of the west jetty. This work will complete the restoration of the west jetty. The west bank of the pass, vicinity miles 6 and 12 below Head of Passes, is very narrow and during high river stages consider- able overbank flow takes place into Dixon and West Bays. The new outlet in the west bank at mile 11.9 should help in building up the narrow west bank area. During fiscal year 1952 a new outlet is proposed in the west bank at mile 6.2. Installation of drift fences to prevent bank erosion is also proposed. Outlet at mile 8.7 (Jahncke Cut) on the east bank of the pass will be closed during fiscal year 1952. Closure will probably be made by hydraulic dredge. Extensive repairs to permeable pile dikes in the pass will be continued during fiscal year 1952 restoring them to a higher elevation, screening, and extending and tying them into the banks of the pass. For last complete report on the existing works of this pass, see pages 966-967 of the Annual Report for 1949. Channel conditions on June 30, 1951, were as follows: 35-foot channel Length Minimum of Minimum Average central channel width width depth Miles Feet Feet Feet Entrance channel into head of the pass.---------------- 1. 0 310 630 133 Through pass from head to sea end of jetties----------- 20. 2 1160 660 35 ---------------- Through bar channel at mouth of pass..... 1.0 660 720 41 1 For short period during high river stage. c. South Pass. A good channel was available throughout the length of the pass during the fiscal year. Maintenance dredg- ing was performed on the sea-bar entrance channel for a short period at the end of the high-water season. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 791 Spur dikes on West Headland permeable pile dike (Southwest Pass side) were straightened and strengthened. Crevasse at mile 2.5, below Head of Passes, on west bank has become temporarily stabilized, but additional stone is needed to prevent further enlargement of this outlet channel. Additional stone should be placed at the upper end of east and west jetties. The east jetty has settled in some locations and should be raised. For last complete report on the existing works of South Pass, see page 967 of the Annual Report for 1949. Controlling channel dimensions on June 30, 1951, were 30 feet deep over a width of 350 feet on the sea-bar channel at the Gulf entrance to the pass. Total costs under the existing project to the end of the fiscal year were $55,402,116.75, of which $25,296,851.85 was for new work and $30,105,264.90 for maintenance. The total expendi- tures were $55,668,707.12. Proposed operations.

(See Corps of Engineers, Mis- sissippi River Commission alluvial valley map, Empire quad- rangle.) Existing project. The plan of improvement provides for con- struction and maintenance of a waterway, 10 miles long, from the State-owned canal and lock at Empire, La., to the Gulf of Mexico to provide a channel 9 feet deep and 80 feet wide, at an estimated cost to the United States of $2,400,000 (revised in 1951), including $1,300,000 for extension of the jetties to the 9-foot depth contour if and when it becomes apparent that such ex- tensions will be more economical than maintenance dredging of the entrance channel. The approved estimate of cost for annual maintenance is $40,000. 'The existing project was authorized by the River and Harbor Act approved July 24, 1946. (See H. Doc. 697, 79th Cong. 2d sess.) The only published map is in this document. Local cooperation. Fully complied with, except for furnishing of title information, preparation of which is under way. Operations and results during fiscal year. Deferred charges covering work by contract performed in the previous fiscal year amounted to $2,827.45, and that by hired labor amounted to $763. The total costs for new work were $3,590.45; expenditures were $2,240.53. Condition at end of fiscal year. The. project is physically complete, unless at a later date it is found necessary to extend the jetties to the 9-foot depth contour. Work on the project was initiated on July 31, 1948, and com- pleted on June 13, 1950, during which period the 9- by 80-foot channel from Empire, La., to the Gulf of Mexico, 10 miles, was excavated by contract. A total of 3,736 linear feet of jetties was constructed by con- tract to the 6-foot depth contour, 1,818 linear feet on east jetty and 1,918 linear feet on west jetty, during the period June 23, 1949, and February 18, 1950. The controlling depths, mean low Gulf (May 1951), were: Over the bar, 8 feet; through the channel, 9 feet. The total costs to the end of the fiscal year were $1,056,639.97, of which $1,056,220 was for new work and $419.97 for mainte- nance; expenditures were $1,056,634.25. Proposed operations.

BAYOU LAFOURCHE, LA. Location. Prior to 1902 Bayou Lafourche*was an outlet of the Mississippi River, its head being at Donaldsonville, La., 80 miles above New Orleans. It flows in a general southerly direction to the Gulf of Mexico, a distance of 107 miles. (See U. S. Coast and Geodetic Survey Charts Nos. 1116 and 1274; Corps of Engineers, Mississippi River Commission alluvial valley map; Donaldson- ville, White Castle, and Napoleonville quadrangles; and United States Geological Survey map and Madewood, Labadieville, La- fourche, Lac des Allemands, Gibson, Houma, Cut-Off, Lake Fe- licity, Mink Bayou, Leeville, and Belle Pass quadrangles.) Previous projects. Authorized by River and Harbor Acts of June 18, 1878, and August 11, 1888. For further details, see page 850 of Annual Report for 1915, page 833 of Annual Report for 1925, and page 791 of Annual Report for 1938. Existing project. This provides for the permanent closure of the head of the bayou, without a lock; for a channel 6 feet deep and 60 feet wide from Napoleonville to the Intracoastal Water- way at Lockport; and a channel of same dimensions from the Intracoastal Waterway at Larose to the Gulf of Mexico via Belle Pass; the closure of Pass Fourchon; and for a jettied entrance at the mouth of Belle Pass. The total length of improvement is about 79.25 miles. Under ordinary conditions the mean range of tide is about 3 inches at the head and 10 inches at the mouth of the bayou. Tropical hurricanes have been known to cause a varia- tion of 10 feet at the mouth and severe rains and overflow have caused a variation of 3 to 10 feet at the head. The estimate of cost for new work, revised in 1951, is $979,000. The latest (1950) approved estimate of cost for annual mainte- nance is $50,000. RIVERS AND HARBORS--NEW ORLEANS, LA., DISTRICT 795 The existing project was adopted by the River and Harbor Act of August 30, 1935 (H. Doc. 45, 73d Cong., 1st sess.). The latest published map is in the project document. Local cooperation. Fully complied with. Terminal facilities. There are numerous private warehouses and wharves and stiff-leg derricks for handling cane along the bayou. At Thibodaux there is a dock with freight transfer and warehouses. At Lockport the Barker Barge Line has a large wharf with covered shed, and the Southern Pacific Railroad maintains a large wharf with covered shed. At Golden Meadow each of the seafood canneries has docking facilities suitable for its needs. Four oil companies have docks at Leeville for trans- ferring the production of the Leeville oil fields to barges. The terminal facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance costs amounted to $5,881.92, of which $2,747 was for supervision, inspection, and patrol of waterway, removal of snags, and main- tenance of signs and markers, and $3,134.92 was for preliminary plans and specifications, all by hired labor; expenditures were $5,418.45. Condition at end of fiscal year. The existing project is 28 percent complete. The dredging between Larose, La., and the Gulf of Mexico was completed in 1939. The jetties at the mouth of Belle Pass were completed in 1939, but were subsequently damaged by storm action, which required the placement of additional stone adjacent to both sides of the steel sheet pile jetties in 1940, and the repair and extension of the jetties in 1941. During the fiscal year 1948 the stone jetties were repaired and extended inland about 700 feet from the shore line; and the steel sheet pile section was strengthened, for about 250 feet Gulfward of the stone jetties, by the placement of stone on both the Gulf and bayou sides. On May 31, 1949, an automatic tide gage for recording hurricane and storm tides was installed. Bids were opened on June 22, 1951, covering repairs to East Jetty, Belle Pass, and award to the low bidder has been recom- mended. Work remaining to be done under the existing project consists of dredging the project channel between Lockport and Napoleon- ville, La. The controlling depths, mean low Gulf (June 1950), were: Over bar, 6.3 feet; through Belle Pass, 7.3 feet; to mile 96, 6.3 feet; to Golden Meadows, 8.3 feet; to Larose, 6 feet; to Lockport (mile 56), 8 feet; to Thibodaux, 6 feet; and to L'Abadieville, 5 feet. The total costs under the existing project to the end of the fiscal year were $571,530.27, of which $271,088.65 was for new work and $300,441.62 for maintenance; expenditures were $571,- 066.80. Proposed operations. The balance unexpended at the end of the fiscal year, $54,069.17, will be applied to accounts payable and repairs to east jetty by contract. 796 REPORT OF CHIEF OF ENGINEERS, U.

LITTLE CAILLOU BAYOU, LA. Location. Little Caillou Bayou has its source in Bayou Terre- bonne, 41/2 miles below Houma, La., and flows 32.8 miles in a southerly direction to Terrebonne Bay. (See U. S. Coast and Geo- detic Survey Chart No. 1116 and U. S. Geological Survey maps, Houma and Dulac quadrangles.) Existing project. This provides for. a channel 5 feet deep at mean low water by 40 feet wide on the bottom from the head of the bayou, at Bayou Terrebonne, to Robinson Canal, about 20 miles. The normal fluctuation of tide is 3 to 6 inches, but winds may raise or lower the water surface about 1 foot. The cost of new work, completed in 1929, was $77,761. The latest (1950) approved estimate for annual cost of maintenance is $9,000. The existing project was authorized by the River and Harbor Act approved January 21, 1927 (Rivers and Harbors Committee Doc. 5, 69th Cong., 1st sess.). Local cooperation. Fully complied with. Terminal facilities. Freight is unloaded directly on or from the banks. This method is considered satisfactory for existing commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. In 1929 the channel was dredged from the head of the bayou (confluence with Bayou Terrebonne) to Robinson Canal, 20.6 miles, obtaining a channel 5 feet deep at mean low Gulf by 40 feet wide on the bottom, and RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 797 completing the project. During the period January 8 and July 21, 1949, the channel was restored to project dimensions by maintenance dredging. The controlling depth, mean low Gulf (May 1950), was Bayou Terrebonne to Robinson Canal, 6 feet. The total costs under the existing project to the end of the fiscal year were $317,894.34, of which $77,761.04 was for new work and $240,133.30 for maintenance. The expenditures were $317,894.34. Proposed operations. The balance unexpended at the end of the fiscal year, $1,600, less a revocation of funds in the amount of $1,285.30, a total of $314.70 will be applied to maintenance consisting of channel patrol. No work is scheduled for the fiscal year 1953.

ATCHAFALAYA RIVER, MORGAN CITY TO THE GULF OF MEXICO, LA. Location. The Atchafalaya River is an outlet of the Mississippi as well as of the Red River. It begins at Old River on the northern boundary of Pointe Coupee Parish and flows generally south a distance of about 170 miles and empties into Atchafalaya Bay, an inlet of the Gulf of Mexico. The section under improvement is from the 20-foot contour in Atchafalaya Bay, 4 miles beyond the mouth of the Atchafalaya River, to the 20-foot contour in the Gulf of Mexico, a distance of about 153/4 miles. (See U. S. Coast and Geodetic Survey Chart No. 1276, Corps of Engineers, Mis- sissippi River Commission alluvial valley map Point au Fer quad- rangle, and navigation maps of Intracoastal Waterway and Atchafalaya River system.) Existing project. This provides for a channel 20 feet deep and 200 feet wide, extending from the 20-foot contour in Atchafalaya Bay 4 miles beyond the mouth of the Atchafalaya River to the 20- foot contour in the Gulf of Mexico, the total length of channel being 153/4 miles. The project depth refers to mean low water. Under ordinary conditions the mean range of tide is about 10 inches, the extreme range of tide about 14 inches. During the hur- ricane of August 1915 there was a rise of tide of about 10 feet. The cost of new work, for the project completed in 1914, was 798 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 $501,963. The latest (1950) approved estimate for annual cost of maintenance is $120,000. The existing project was adopted by the River and Harbor Act of June 25, 1910 (H. Doc. 669, 61st Cong., 2d sess.). The latest published map accompanies House Document No. 410, Fifty-sixth Congress, first session. Terminal facilities. At Morgan City there are several small private wharves and two large and three small public wharves open to the use of all without charge. There are no warehouses needed, as the business section is on the river front and all freight is transferred directly from boats to stores. The facilities are considered adequate for the existing commerce. Operations and results during fiscal year. Maintenance of signs and markers was carried on by hired labor at a cost of $39; expenditures were $496.97. Condition at end of fiscal year. The existing project was com- pleted in 1914. The controlling depths, mean low Gulf (July 1950), were: Over the bar, 7.5 feet; through Atchafalaya Bay, 9 feet; to Morgan City, 32 feet. Demands of present commerce indicate maintenance of recent years inadequate. Depths more nearly that of the adopted project are necessary. The total costs under the project to the end of the fiscal year were $787,352.90, of which $501,963.23 was for new work and $285,389.67 for maintenance; expenditures were $787,352.90.

There are privately owned terminals for trans- ferring crude oil to barges near the towns of Charenton, Jean- erette, Olivier, and St. Martinville. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Supervision, inspec- tion and patrol of waterway, maintenance of markers, snagging, and removal of overhanging trees and other obstructions were continued by hired labor at a cost of $1,000 for maintenance. Costs for preparation of preliminary plans and specifications amounted to $2,931.81. Keystone lock was operated throughout the fiscal year, and the lock, dam, structure, and grounds were maintained, as necessary, and routine work thereon was performed, all at a cost of $17,- 349.77. The water system on the reservation was repaired at a cost of $3,253 and installation of electric system was commenced, with costs of $457 for operating and care. The total costs were $24,991.58, of which $3,931.81 was for maintenance, and $21,059.77 for operating and care; the expendi- tures were $25,165.92. Condition at end of fiscal year. The existing project is ap- proximately 71 percent complete. Keystone lock and dam were completed in 1913. The dredging and snagging done in 1916 completed that part of the existing project for the 6- by 50-foot channel from Arnaudville to Key- stone lock. The contract dredging done in 1918-20 completed that part of the previous project for a 6- by 50-foot channel from Keystone lock to mile 39.7 above the mouth. The 8- by 80-foot channel from New Iberia to the mouth is 98 percent complete. From the mouth to mile 5.8 a channel 8 by 80 feet, or greater, already existed, and a new channel has been excavated, 8 by 80 feet from this point to mile 50.06, about 3.65 miles below New Iberia, and 8 by 60 feet from this point to New Iberia. The work required to complete the existing project is the widening of channel to a bottom width of 80 feet from mile 50.06 to New Iberia, and to a bottom width of 60 feet from New Iberia to Keystone lock.

S. ARMY, 1951 13. PETIT ANSE, TIGRE, AND CARLIN BAYOUS, LA. Location. Bayou Tigre is a tributary of Bayou Carlin; Bayou Carlin is a tributary of Bayou Petit Anse. Bayou Petit Anse has its source in Iberia Parish about 5 miles northwest of New Iberia. It flows in a southwesterly direction for about 15 miles to its intersection with the Intracoastal Waterway, thence for a dis- tance of about 3 miles to Vermilion Bay. Bayou Tigre has its source in Vermilion Parish about 6 miles northeast of Abbeville and flows in a southerly direction for about 7 miles to its junction with Bayou Carlin. Bayou Carlin has its source in Lake Peigneur in Iberia Parish and flows in a southerly direction about 7.5 miles to its confluence with Bayou Petit Anse at a point about 2.3 miles above the Intracoastal Waterway. (See U. S. Coast and Geodetic Survey Chart No. 1116, Corps of Engineers, Mississippi River Commission alluvial valley map and Derouen quadrangle, and U. S. Geological Survey map Abbeville, N. E., quadrangle.) Existing project. This provides for dredging a channel in Bayou Petit Anse 9 feet deep and 80 feet wide from the Intra- coastal Waterway to the north end of Avery Island; a channel 5 feet deep and 40 feet wide from the Intracoastal Waterway via the McIlhenny Canal (Avery Canal) to deep water in Vermilion Bay; and a channel 9 feet deep over a bottom width of 80 feet in Bayou Carlin from Bayou Petit Anse to Lake Peigneur. The total length of the improvements is 16.1 miles. Under ordinary conditions the mean range of tide is about 10 inches. The cost of completing the project (in fiscal year 1950) was $298,314. The latest (1950) approved estimate for annual cost of maintenance is $10,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Aug. 30, 19351 A channel in Bayou Petit Anse 60 feet wide and 9 feet H.

Local cooperation. Fully complied with except for furnishing suitable terminal at head of Avery Island; however, assurances have been accepted by the Department of the Army. Title to the right-of-way, has been conveyed to the United States. Under a permit issued March 24, 1937, the Texas Pipe Line Co. enlarged the 5- by 40-foot channel in Bayou Petit Anse above mile RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 803 3.2 to a depth of 9 feet and a width of 80 feet at an estimated cost of $30,000. Terminal facilities. There is an extensive oil terminal at the head of the improvement on Bayou Petit Anse and several private docks and cane hoists. (Terminal facilities are further described in H. Doc. 225, 72d Cong., 1st sess.) These facilities are consid- ered adequate for existing commerce. Operations and results during fiscal year. Maintenance costs in the amount of $1,842.17 covered supervision, inspection, and patrol of the waterway at a cost of $368.17, and preparation of plans and specifications at a cost of $1,474, all by hired labor. Expenditures were $2,024.20. Condition at end of fiscal year. All work under the project, as existent at that time, was completed in 1939; and the work authorized by the River and Harbor Act approved March 2, 1945, for a 9- by 80-foot channel was completed in 1947, except dredg- ing in the vicinity of Texas and New Orleans Railroad bridge and Louisiana State Highway Department bridge crossing Bayou Carlin, which was accomplished during 1949, as was reinforce- ment of bridge piers under reimbursable agreement, authorized by River and Harbor Act approved June 30, 1948. The modified project is complete, except that the Jefferson Island Salt Co. has partially complied with furnishing a 9- by 80-foot canal connect- ing Bayou Carlin with their salt mine, as provided in the authorized document. The Chief of Engineers has accepted a 9- by 60-foot channel as partial completion and this 9- by 60-foot channel has been excavated for the full length prescribed. The controlling depths, mean low Gulf (May 1950), were: Bayou Petit Anse: Gulf Intracoastal Waterway to head of Navi- gation, mile 6.1, 9 feet; Bayou Tigre: Impossible to enter bayou due to shoal at mouth; Bayou Carlin: Mile 0 to mile 6.3, 9 feet; to mile 7.6, 8 feet; Mcllhenny Canal (Avery Canal): Gulf Intra- coastal Waterway to Vermilion Bay, 8.5 feet; over bar, 4 feet. The total costs under the existing project to the end of the fiscal year were $345,475.79, of which $298,313.79 was for new work, including $47,858.13, Public Works funds, and $47,162 from regular funds for maintenance. The total expenditures were $345,475.62. Proposed operations. No work is scheduled during fiscal year 1952.

CALCASIEU RIVER AND PASS, LA. Location. Calcasieu River has its source in southwestern Louisiana, and flows in a general southerly direction to the Gulf of Mexico. About 25 miles from the Gulf it debouches into Cal- casieu Lake, which lake is about 18 miles long. The connection between the lake and the Gulf, about 7 miles long, is known as Calcasieu Pass. (See U. S. Coast and Geodetic Survey Charts Nos. 591 and 592; U. S. Geological Survey maps, Edna, Thompson Bluff, Hecker, Moss Bluff, Lake Charles, West Lake, Moss Lake, Hackberry, Sweet Lake, Brown's Lake, Holly Beach, Grand Bayou and Cameron quadranges; and Corps of Engineers naviga- tion maps of Intracoastal Waterway and Atchafalaya River system.) Previous projects. The original project for this improvement was adopted by the River and Harbor Act of June 10, 1872. Ap- propriations were made by the River and Harbor Acts of March 3, 1881, August 2, 1882, July 5, 1884, and August 11, 1888. The project was modified by the River and Harbor Acts of Septem- ber 19, 1890, July 13, 1892, and September 22, 1922. For further details, see Annual Report for 1936, page 719, and Annual Re- port for 1938, page 819. Existing project. This provides for a channel 35 feet deep and 250 feet wide (102.1 miles long) from the wharves of the Lake Charles Harbor and Terminal District by way of Calcasieu River including Clooney Island Loop, to the head of Choupique cut-off; thence by a land-and-water cut along the west shore of Calcasieu Lake; thence to and through Calcasieu Pass by a designated route to the Gulf of Mexico, subject to such change in alignment as is approved by the Chief of Engineers; the reconstruction and extension of the existing jetties initially to the seaward end of the east jetty, and further extension to the 15-foot depth con- tour if found advisable to reduce maintenance dredging costs; dredging a channel 35 to 37 feet deep and 250 feet wide between jetties, and an approach channel 37 feet deep and 400 feet wide from the sea end of the jetties to a depth of 37 feet in the Gulf of Mexico; also for the improvement of the river from Lake Charles to Phillips Bluff by removing logs, snags, overhanging RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 805 trees, and by dredging. Total length of improvement is 102.1 miles. Under ordinary conditions, the mean range of tide is 10 inches at the mouth, diminishing to zero at Phillips Bluff, the extreme range being 14 inches and zero, respectively. The estimate of cost for new work, including $3,400,000 for the extension of the jetties to the 15-foot depth contour, revised in 1951, is $12,981,000. The latest (1950) approved estimate for cost of maintenance is $278,000 annually.

Local cooperation. Fully complied with. Under date of January 5, 1922, a permit was granted by the Assistant Secretary of War to the police jury of Calcasieu Parish to enlarge this river where necessary between Lake Charles and the eastern end of the Calcasieu-Sabine section of the Intracoastal Waterway to a depth of 30 feet over a bottom width of 125 feet. Terminal facilities. Terminal facilities at the Port of Lake Charles are owned by the Lake Charles Harbor and Terminal District and operated by a board of commissioners. In addition to the municipally owned terminals, there are several privately owned and operated wharf structures located on the existing ship channel. (For further details see Port Series No. 21, "The Port of Lake Charles, La." revised 1947.) Operations atd results during fiscal year. Preparation of plans and specifications, surveys, and report on model study, were carried on at a cost of $4,753.63, real estate activities amounted to $215, and the U. S. dredge Langfitt worked intermittently in the Calcasieu River approach and bar channel during the period October 15, 1950, and June 28, 1951, removing 4,210,728 cubic yards, making the job 26 percent complete, with costs of $389,673, all new work by hired labor. The dredge Mobile removed 193,151 cubic yards during the period July 26 and August 6, 1950, in dredging a channel to project dimensions between miles 30.4 and 32.0 under continuing contract with costs of $72,291, new work. Hired labor forces carried on surveys, supervision and inspec- tion of the waterway, and clearing and snagging operations at a cost of $7,955.38 for maintenance. 806 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The total costs were $474,888.01, of which $466,932.63 was for new work and $7,955.38 for maintenance; expenditures were $474,131.26. Condition at end of fiscal year. The project as modified is 50 percent complete. Dredging under the existing project, prior to the modifications adopted by the River and Harbor Acts of March 2, 1945, and July 24, 1946, was completed in 1941, and the 30- by 250-foot ship channel was formally opened to deep draft traffic on July 12, 1941. Work on the modified project of deepening the 250-foot channel to 35 feet from Lake Charles Harbor to the 37-foot depth contour in the Gulf of Mexico was initiated on September 7, 1948, and at the end of the fiscal year was completed from Lake Charles Harbor, including Clooney Island Loop, to the approach channel in the Gulf of Mexico.

Oct. 16, 1950 June 27, 1951 The Calcasieu Pass jetties, initiated under the previous project and completed in May 1942, extend to the 10-foot depth contour and are in good condition. The East Jetty, approximately 8,620 feet long, has been built to approximately 6 feet above mean low Gulf, and extends seaward from the existing Gulf shore line a distance of 6,820 feet. The West Jetty, 8,050 feet long, has been built to approximately 4 feet above mean low Gulf and ex- tends seaward from the existing Gulf shore line a distance of 6,795 feet. The jetty structure is considered complete unless at a later date it is found necessary to extend the jetties seaward to the 15-foot depth contour, as provided for in the project. Work remaining to be done, consists of completing the ap- proach channel to the 37-foot depth contour in the Gulf, extend- ing the jetties seaward to the 15-foot depth contour, if and when found necessary, and constructing approaches and ramp to ferry crossing Calcasieu River and Pass. RIVERS AND HARBORS--NEW ORLEANS, LA., DISTRICT 807 The controlling depths, mean low Gulf (June 1951), were: Over outer bar, 33 feet; over inner bar (slush at 27 feet), 34 feet; through jetty channel, 35 feet; lower jetty channel to Lake Charles (slush at 32 feet), 34 feet. The total costs of the existing project to the end of the fiscal year were $7,692,125.07, of which $6,539,220.37 was for new work and $1,152,904.70 was for maintenance.

REMOVING THE WATER HYACINTH (LOUISIANA) Location. Lakes and streams tributary to the Gulf coast. Existing project. This project provides for the extermination or removal of plants from the navigable waters of the States of Florida, Alabama, Mississippi, Louisiana, and Texas, so far as they are or may become an obstruction to navigation, by any mechanical, chemical, or other means whatsoever; for the con- struction and operation of boats equipped with suitable machinery for such removal; and for the construction and operation of booms to prevent the drifting of plants from one stream to an- other. The latest (1950) approved estimate for annual cost of maintenance is $500,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents Mar. 3, 1899 Made appropriations for the States of Florida and H. Doc. 91, 55th Cong., 3d sess. Louisiana and provided for the extermination or removal of plants, the building of boats, and the establishment of booms.

The terminal facilities of the various streams from which hyacinths were removed are described in the report for the improvement of these streams. RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 809 Operations and results during fiscal year. A combination of mechanical and chemical methods of destruction was employed to obtain maximum results with minimum expenditure of funds. The results thus obtained, together with severe freezes and work accomplished in feeder area during the preceding year, resulted in several areas being placed on a patrol maintenance basis, while other areas acting as recipient basins or "traps" required con- siderable work to maintain open channels. A total of 16,914,- 804 square yards of vegetation was destroyed by chemicals and 19,321,750 square yards of vegetation were destroyed by ma- chinery in streams of the Atchafalaya Basin, Bayou Black, Lake Cataouatchie and feeder streams, streams of the Lake des Allemands Basin, the Intracoastal Waterway and its feeder streams, Bayou Lafourche, streams of the Lake Maurepas Basin, the Bayou Penchant-Bayou Copassaw area, the Plaquemine Waterway and feeder streams, Lake Pontchartrain and connect- ing streams, and in Bayou Teche. Two aquatic vegetation destroyers of the semi-submerged, rotary saw type and three spray pontoons were employed during the year. The mechanical destruction plant Kenny was main- tained in reserve status during part of the year and plans are now underway to strip off component parts for reuse elsewhere. No hand removal work was undertaken and all conveyors have been sold. Lack of sufficient operating fund resulted in a com- plete shutdown for two months during the cold weather season when it was felt that the least damage would result. Work was undertaken only in the principal streams of the district over which the greater portion of water-borne traffic moved and in areas which would have suffered severe hardship if work had not been undertaken. The total costs during the fiscal year were $269,879.99 and the total expenditures were $271,172.86, all for maintenance. Condition at end of fiscal year. From 1900 to 1902 a boat with suitable machinery for removing and crushing hyacinths was operated. From that time until 1936, the hyacinths were con- trolled by spraying with a solution of arsenic and caustic soda, removal by hand crews, and by means of booms and barricades. The use of arsenic and caustic soda has been discontinued and hand removal has been supplanted by the use of mechanical equipment in conjunction with the chemical spray 2,4-Dichloro- phenoxy-acetic acid. Present methods of control are by means of mechanical rotary saw type destroyers, chemical treatment and booms and barricades. Excellent results are being obtained within the limits of available funds which have been severely curtailed because of the present emergency. The total costs to the end of the fiscal year were $3,343,398 for maintenance; expenditures were $3,341,370.52. Proposed operations.

CHANNEL IMPROVEMENT UNDER AUTHORITY OF SECTION 3 OF THE RIVER AND HARBOR ACT APPROVED MARCH 2, 1945 (BAYOUS TERRE AUX BOEUFS AND SEGNETTE, LA.) The River and Harbor Act approved March 2, 1945, authorized the allotment of not to exceed $300,000 from river and harbor appropriations for any one fiscal year for the removal of accumu- lated snags and other obstructions and for protection, clearing, and straightening channels in navigable harbors, streams, and tributaries thereof when such work is advisable in the interest of navigation. During the fiscal year 1950 an allotment of $25,000 was re- ceived to provide a 5- by 50-foot clear channel in Bayou Terre aux Boeufs for navigation, by clearing and snagging between miles 10.5 and 18.25, and clearing, snagging, and dredging be- tween miles 18.25 and 19.5. This work was accomplished by con- tract during the period April 4 and 30, 1951, at a cost of $24,500. Hired labor costs in connection with this dredging amounted to $252.70 for preparation of preliminary plans and specifications. Expenditures were $24,831.55. During the fiscal year 1951 an allotment of $25,000 was re- ceived to provide an 8- by 50-foot clear channel in Bayou Seg- nette, La., between miles 1.5 and 5.5. This work was commenced on June 7, 1951, by hired labor and at the end of the fiscal year was completed between miles 2 and 3.3, with costs in the amount of $8,268. Additional hired labor costs for surveys, investiga- tions, and preparation of plans and specifications for this dredg- ing amounted to $398. Expenditures were $3,072.69. Proposed operations. The balance unexpended at the end of the fiscal year, $21,927.31, will be used to complete hired labor dredging on Bayou Segnette.

SNo commerce reported. SChannels adequate for existing commerce. Abandonment recommended in 1926 (H. Doc. 467, 69th Cong., 1st sess.). This project has not been completed as it has been superseded for most of its length by the 12 x 125-foot Gulf Intracoastal Waterway which coincides with or parallels it. Costs and ex- penditures prior to July 1, 1939, are reported under previous projects of the Gulf Intracoastal Waterway between Apalachee Bay, Fla., and the Mexican border (New Orleans district). I 8 No work has been performed in the New Orleans District under this title. Increase over maintenance costs as of June 30, 1950, represents expenditures for accounts payable as of June 30, 1950. * Increase over maintenance cost as of June 30, 1950, represents costs in connection with obtaining rights-of-way during fiscal year 1951. 9 Due to decline of traffic, local interests are no longer sufficiently interested to provide rights-of-way and dumping privileges. 10 This is a maintenance project and no future work is scheduled.

LAKE PONTCHARTRAIN, JEFFERSON PARISH, LA. Location. The work covered by this project lies on the south- ern shore of Lake Pontchartrain in Jefferson Parish, between the Orleans and St. Charles Parish lines. (Mississippi River Commis- sion alluvial valley map, smale 1:250,000 and quadrangle maps, scale 1:62,500.) Previous project. The previous project, authorized by the Flood Control Act approved July 24, 1946 (H. Doc. 691, 79th Cong., 2d sess.), was revised by the Flood Control Act approved May 17, 1950 (S.Doc. 139, 81st Cong., 2d sess.), to become feature of the project for flood control, Mississippi River and a tributaries. Operations and results during fiscal year. Surveys, engineer- ing, preparation of plans and specifications, and obtaining rights- of-way without reimbursement, were performed during the year. Hired labor forces completed the interim protection throughout the lake front levee by topping on July 21, 1950, and during the period October 23 and December 22, 1950, enlarged the pro- tection levee from the Illinois Central Railroad to the Airline Highway by placing 55,929 cubic yards of fill. On September 22, 1950, topping the St. Charles-Jefferson Parish line levee was completed, with only dressing accomplished this fiscal year. On April 30, 1951, work was initiated on enlarge- ment of a portion of the lake shore levee of Lake Pontchartrain, consisting of approximately 505,770 cubic yards of hydraulic fill, and at the end of the fiscal year the contractor had built 3,083 linear feet of landside and 4,485 linear feet of lakeside re- taining dikes. The total costs were $83,218.14 for new work; expenditures were $100,917.55. Condition at end of fiscal year. Construction work under the project commenced on December 1, 1948, with the enlargement of the lake shore levee of Lake Pontchartrain, which was com- pleted on December 19, 1949. This levee was topped during the period March 30 and July 21, 1950, and additional enlargement was initiated on April 30, 1951, and is now in progress with 3,085 linear feet of landside and 4,485 linear feet of lakeside FLOOD CONTROL-NEW ORLEANS, LA., DISTRICT 841 retaining dikes completed. The St. Charles-Jefferson Parish line levee was enlarged during the period January 26 and August 16, 1949, topped during the period March 17 and September 22, 1950, and the enlargement was extended from the Illinois Central Railroad to the Airline Highway, 4,319 linear feet, during the period October 23 and December 22, 1950. The levee along the Orleans-Jefferson Parish line from the Seventeenth Street Canal pumping station to Lake Pontchartrain was completed during the period June 9 and November 16, 1949. During the period June 6 and 10, 1949, hired labor forces extended the wavewash protection on the lake shore levee with salvage rubble removed from behind lakeside dike at East End. Upon completion of work in progress, "Flood Control, General," funds will be exhausted, and all work remaining to complete the project will be accomplished with "Flood Control, Mississippi River and Tributaries" funds, when they become available, to which project "Lake Pontchartrain, Jefferson Parish, La.," was transferred by the Flood Control Act approved May 17, 1950. The total government costs to the end of the fiscal year were $1,151,827.22; expenditures were $1,151,780.66. In addition, costs and expenditures from contributed funds amounted to $626,600.

BAYOU TECHE AND VERMILION RIVER, LA. Location. Bayou Teche has its source in Bayou Courtableau, in St. Landry Parish, and flows in a southeasterly direction a distance of 125 miles to its confluence with the lower Atchafalaya River, about 101/2 miles above Morgan City, La. Vermilion River, also called Bayou Vermilion, is formed by the junction of Bayous Fusilier and Bourbeau, west of Arnaudville, La., and flows in a southwesterly direction to the western end of Vermilion Bay, a distance of 72 miles. Bayou Teche is connected with the Vermilion River by Bayou Fusilier at Arnaudville; and by Ruth Canal, an artificial, privately owned, nonnavigable waterway, constructed for diversion of water from Bayou Teche to Vermilion River for rice irrigation. (U. S. Coast and Geodetic Survey Charts Nos. 1116 and 1277; Corps of Engineers, Mississippi River Commission allu- vial valley maps; and U. S. Geological Survey maps.) Existing project. This provides for the excavation of a navi- gable channel (51 miles long) 8 feet deep and 80 feet wide from the 8-foot depth contour in Vermilion Bay to the Gulf Intracoastal Waterway, thence 9 feet deep by 100 feet wide from the Gulf Intracoastal Waterway to Lafayette, La. (fixed bridge at Louisi- ana State Highvay No. 1092), with additional enlargement below Abbeville necessary to provide adequate capacity for flood flows; channel improvement of the nonnavigable channel of Vermilion River and Bayou Fusilier from Lafayette, La., to Bayou Teche at Arnaudville, La., of adequate capacity to carry flood flows of the upper Vermilion Basin, a 1.5-foot increase in the pool elevation of Bayou Teche above Keystone Dam and the enlargement of the nonnavigable channel of Bayou Teche from its head at Bayou Courtableau to a point approximately 21 miles downstream. Under ordinary conditions the mean range of tide on Vermilion Bay is 1.1 feet. The variation of the water surface near the mouth may be as much as 7 or 8 feet, due to hurricanes on the Gulf. The plane of reference is mean low Gulf level. (See also in- dividual report of navigation project for Bayou Teche, La.) The current estimated Federal cost of new work, approved in 1951, is $2,945,000. The estimated local cost of new work is $150,- 000. The latest (1948) approved estimate of Federal cost of annual maintenance is $25,000. FLOOD CONTROL--NEW ORLEANS, LA., DISTRICT 843 The existing project was authorized by the Flood Control Act of August 18, 1941. (S. Doc. 93, 77th Cong., 1st sess., which also contains the latest published map.) Local cooperation. Fully complied with. Operations and results during fiscal year. Procurement of local cooperation in obtaining rights-of-way and preparation of plans and specifications were continued. Gages, surveys, observations and supervision, inspection, and patrol of the waterway were carried on by hired labor at a cost of $7,663 for maintenance. Channel improvement of Bayous Vermilion and Fusilier between miles 57.22 and 76.21 was accomplished by contract during the period August 21, 1950, and June 26, 1951, with 1,705,902 cubic yards of excavation, 301 cubic yards of earth fill placed in Bayou Fusilier at mile 76.21, and five timber bridges modified; railroad bridge No. 3.78 was modified by contract during the period March 5 and 12, 1951, and bridges over Bayou Vermilion, mile 70.13, Louisiana State Highway No. 988, and over Bayou Fusilier, mile 75.46, Louisiana State Highway No. 245, were modified by reim- bursable contract during the period December 11, 1950, and June 30, 1951. The total costs were $219,776.56, of which $212,113.56 was for new work and $7,663 for maintenance; expenditures were $193,- 215.36. Condition at end of fiscal year. The project is approximately 92 percent complete. Channel improvement on Vermilion River consisted of con- structing an 8- by 80-foot channel from the 8-foot depth contour in Vermilion Bay to the Gulf Intracoastal Waterway; a 9- by 100-foot channel from Gulf Intracoastal Waterway to mile 52; and a 6- by 60-foot channel from mile 52 to mile 57.4. Channel en- largement was accomplished between miles 3.5 and 17.5 and 57.4 and 76.21. Clearing and snagging was accomplished in Bayou Fusilier and Bayou Vermilion between miles 67.7 and 79, and an earth dike was constructed in Bayou Fusilier. The channel of Bayou Teche was improved between miles 103.8 and 124.8. A new bridge was constructed over Vermilion River at Woodlawn, the bridge at Milton was reconstructed; modification of bridges numbered 3.78 and .988 over Bayou Vermilion and bridge num- bered 245 over Bayou Fusilier has been accomplished; the bridge at Pinhook was altered, and riprap was placed to insure bridge against possible damage by bank caving; and excavation and riprapping was performed in the vicinity of Southern Pacific Railroad bridge, Lafayette, La. Local interests have constructed improvements in Ruth Canal. Work remaining to complete the project consists of raising the crest of Keystone dam, a feature of the River and Harbor project "Bayou Teche, La.," to provide an increase of 1.5 feet in the pool elevation above Keystone dam, in order to increase the flow through Ruth Canal into Vermilion River, and miscellaneous minor items. This work will be accomplished in connection with the reconstruction of Keystone dam under the Bayou Teche, La., 844 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 project. Due to sedimentation caused by deposits from tributary streams recently excavated by local interests, it will be necessary to redredge the Vermilion River channel between miles 26 and 52, to reestablish project dimensions. The controlling depths (September 1949), Vermilion River, were: Over the bar, 4.5 feet; to Gulf Intracoastal Waterway, 6.5 feet; to Pinhook Bridge (Lafayette), 6 feet; and to Ruth Canal, 3 feet. The total costs under the existing project to the end of the fiscal year were $2,784,166.47, of which $2,697,090.30 was for new work and $87,076.17 for maintenance. The total expenditures were $2,756,352.38. Proposed operations.

MERMENTAU RIVER, LA. Location. The work covered by this project is located 35 to 70 miles southeast of Lake Charles, La., along the lower Mermentau River below Grand Lake, mile 25, to the Gulf of Mexico; the In- land Waterway from Vermilion Bay to White Lake, White Lake to Grand Lake, and from Schooner Bayou to the Intracoastal Water- Way-Gulf section (Schooner Bayou cut-off) ; the North Prong of Schooner Bayou; and the waterway from White Lake to Pecan Island, La., and artificial canal, extending from the 5-foot-depth contour in White Lake, almost due south for a distance of ap- proximately 1.8 miles to Pecan Island. (See U. S. Coast and Geodetic Survey Charts Nos. 1277 and 1278, and U. S. Geological Survey maps.) Existing project. The plan of improvement covers flood con- trol, navigation, irrigation, and salinity control in the coastal marsh of the lower Mermentau River Basin and provides for channel enlargement of the lower Mermentau River below Grand Lake, mile 25, to a minimum section of 3,000 square feet below mean low Gulf level for discharge of flood flows; construction of a sector gated control structure at Catfish Point, mile 24 above mouth of Mermentau River for discharge of flood flows and con- trol of tidal flows and salt water intrusion in the Mermentau River; channel enlargement and realignment of the Inland Water- way from Vermilion Bay to White Lake and from White Lake to Grand Lake to a minimum section of 3,000 square feet below mean low Gulf level or interflow between lakes and discharge of flood flows; construction of a sector gated control structure in the enlarged channel immediately north of the existing Schooner Bayou Lock Reservation for discharge of flood flows and control of tidal flows and salt water intrusion; channel enlargement of North Prong of Schooner Bayou and Schooner Bayou cut-off to 6 by 60 feet, mean low Gulf level, for navigation purposes; and maintenance of the existing 5- by 40-foot, mean low Gulf level, waterway from White Lake to Pecan Island, La., for navigation. In addition, the project provides for the incorporation of that section of the project, "Inland Waterway from Franklin, La., to 846 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Mermentau River," west of Vermilion Bay, a waterway that in- cluded the Schooner Bayou lock. Because of the failure of both east and west gates, Schooner Bayou lock has been closed by a dike across the east approach channel and traffic has been routed through the new control structure. Under ordinary conditions the mean range of tide on the Mer- mentau River near the mouth is 1.6 feet and near the head about 3 inches. The variation of the water surface near the mouth may be as much as 7 or 8 feet, due to hurricanes on the Gulf, and near the head from 8 to 12 feet, due to freshets. The current estimate of cost for new work, approved in 1951, is $5,000,000. The latest (1950) approved estimate for annual cost of maintenance and operation is $93,600, of which $46,000 is for operating and care of the control structures.

A total of 8,235,481 cubic yards were removed in improving approximately 15 miles of channel and excavating Catfish Point control structure ap- proach channels at a cost of $1,223,763.94 for new work by con- tract as follows: Completing excavation of White Lake to Ver- milion Bay, which was under construction in beginning of fiscal year, by the removal of 2,983,993 cubic yards by the dredge Duplex during the period January 19 and May 31, 1951, and 1,099,067 cubic yards by the dredge Port Arthur during the period July 1 and September 8, 1950; initiating and completing excavation of Grand Lake to White Lake, by the removal of 3,562,304 cubic yards by the dredge Port Arthur during the period September 10, 1950, and February 16, 1951, and of Catfish Point control structure approach channels, by the removal of 583,917 cubic yards by the dredge Pontchartrain during the period February 16 and May 3, 1951, and 6,200 cubic yards by draglines during the period December 16 and 31, 1950. FLOOD CONTROL-NEW ORLEANS, LA., DISTRICT 847 Schooner Bayou control structure and Catfish Point control structure, in progress as beginning of fiscal year, were completed on May 22, 1951, and October 20, 1950, respectively, with costs for the fiscal year of $603,677.36, new work, contract. Deferred charges for contract work completed during the previous fiscal year amounted to $325.33, and preliminary gov- ernment costs for channel excavation of Mermentau River be- tween miles -0.5 and 8.16 amounted to $1,946. Preparation of detailed plans and specifications, design, miscel- laneous soil investigations, surveys, and preliminary plans and specifications were continued at a cost of $25,130.75, and replace- ment of liquid butane line and coating operating cables for steel gates at Catfish Point control structure were accomplished at a cost of $1,485, all new work by hired labor. Surveys and observations, inspection and patrol of the water- way, and geological investigations and studies were carried on by hired labor at a cost of $12,062 for maintenance. The lock and structures were operated, as required, during the fiscal year; the lock, structures, and grounds were maintained, and all necessary and routine maintenance work thereon per- formed at a cost of $19,667 for Schooner Bayou lock, and $13,495 for Catfish Point control structure. Due to failure of the gates at Schooner Bayou lock, emergency closure of the approaches, to prevent salt-water intrusion, was accomplished by the leased dredge Duplex on May 16, 1951, at a cost of $6,448 for mainte- nance. Closure of the Mermentau River opposite the Catfish Point con- trol stucture during the period April 13-19, 1951, eliminated the last point of uncontrolled salt-water intrusion of the Mermentau Basin and White Lake, and the project was placed in operation for conservation of fresh water for irrigation use. Due to pro- longed period of unusually low rainfall, extending from February through the end of the fiscal year, the requirements for irrigation have been very great. Very large benefits have been produced by the project in its first year of operation by providing the required irrigation at a time when the water in the Mermentau Basin would have been too salty for use. The total costs were $1,908,000.38, of which $1,856,328.38 was for new work, $18,510 for maintenance, and $33,162 for operating and care. 'The expenditures were $1,931,234.11. Condition at end of fiscal year. The project is approximately 85 percent complete. Dredging of the 5- by 40-foot waterway from White Lake to Pecan Island, La., was completed in 1931.

S. ARMY, 1951 2. OUACHITA AND BLACK RIVERS, ARK. AND LA. Location. Ouachita River rises in Polk County, Ark., and flows about 600 miles in a general southeasterly and southerly direction through Arkansas and Louisiana. It is joined by Tensas and Little Rivers at Jonesville, La., below which place it is called Black River, and enters Red River 35.5 miles above its mouth. (See Mississippi River Commission alluvial valley map and Moro Bay, Ingalls, Strong, Felsenthal, Haile,'Drew, Monroe, Columbia, Fort Necessity, Harrisonburg, Manifest, Tooleys, and Deer Park quadrangle maps.) Previous projects. The project was adopted by the River and Harbor Acts of March 3, 1871, June 10, 1872, August 14, 1876, and July 5, 1884. A separate project for work in the Ouachita River between Camden and Arkadelphia was adopted by the River and Harbor Act of August 11, 1888. For further details, see page 1869 of the Annual Report for 1915, and page 900 of the Annual Report for 1938. Existing project. This provides for a navigable depth of 61/2 feet at low water from the mouth of Black River, La., to Camden, Ark., a distance of 351 miles, by the construction of six locks and dams, with necessary dredging, and for removal of logs, wrecks and overhanging trees, etc., between mouth of Black River and Arkadelphia, Ark., 417 miles, and for a channel 7 feet deep and of suitable width from the improved channel of the Ouachita River above dam No. 6 to the vicinity of the railroad bridge over Lake St. Mary, thence a canal of the same depth and 70 feet in width along the south side of the railroad embankment to high ground with a suitable turning basin near Felsenthal, a distance of 3,600 feet. The project also provides for operation and care of all locks and dams included therein. The River and Harbor Act of May 17, 1950, authorized the modification of the existing project and the project for the Red River below Fulton, Ark., to provide a channel 9 feet deep and 100 feet wide from the authorized 9-foot navigation project at mile 31 on the Red River to the mouth of Black River at mile 35.5, thence from the mouth of Black River to Camden, Ark., mile 351 on the Ouachita River, to be obtained by lengthening and deepening the six existing locks, channel realignment cut- offs where necessary, rehabilitation of the dams, dredging and contraction works, including the deepening of the Felsenthal Canal below the present authorized depth. The location and description of the locks and dams which are included in the project are contained in the table following: Locks and dams, Ouachita River, Ark. and La.

S. ARMY, 1951 Floods ordinarily cause fluctuations of stage from 25 to 45 feet between high and low water. Extreme floods occasionally increase this range about 10 feet. The flood of March-April 1945 produced crest stage at Monroe, La., 0.7 foot higher than the maximum previously recorded. The latest approved (June 1951) estimate of cost for new work is $16,958,000 which includes $58,000 for Felsenthal Canal. The latest approved (June 1951) estimate of cost for annual mainte- nance is $500,000.

Local interests are required to give assur- ances satisfactory to the Secretary of the Army that they will furnish free of cost to the United States all lands, easements, rights-of-way, and overflow and spoil disposal areas necessary for the construction of the project and subsequent maintenance as and when required; bear the cost of alteration or replacement of existing highway bridges where necessary; provide adequate terminal an transfer facilities, open to all on equal terms; and hold and save the United States free from damage due to the construction works. Fully complied with for completed portions of the project. Terminal facilities. At Monroe La., there is one private elec- tric crane and one private warehouse. At West Monroe there are two private warehouses. At Camden, Ark., there are three pri- vate warehouses. At Champagnolle Landing there is a private dock for the loading of gasoline into barges. At Sterlington, La., there is a private loading dock. At Calion, Ark., there is a private conveyor and dock for unloading logs. These facilities are not considered adequate for present commerce. RIVERS AND HARBORS-VICKSBURG, MISS., DISTRICT 865 Operations and results during fiscal year. Maintenance dredg- ing was done in the channel of the stream at 40 locations between Camden, Ark., and the mouth of Black River. A total of 753,807 cubic yards of material was moved, including 426,938 cubic yards by the contract dredge Vicksburg, and 326,869 cubic yards by United States cutter-head dredge Todd. The six locks and dams were operated and maintained in a satisfactory condition throughout the fiscal year by hired labor. The total costs during the fiscal year were $525,871.01 of which $165.02 was for snagging, $334,478.12 was for maintenance dredging, and $191,227.87 for operating and care. The total ex- penditures were $629,141.38. Condition at end of fiscal year. The project providing for a depth of 6.5 feet has been completed and is being maintained. New work under the modified project has not been started. The six locks and dams embraced in the existing project for slack-water improvement of the Ouachita River were completed in 1924 and provide navigation to Camden, Ark. (See table under existing project.) Construction of the canal to Felsenthal, authorized in 1937, has not been started. The head of navigation is Arkadelphia, Ark., to which point boats may occasionally run during high water if snags, over- hanging trees, or similar obstructions do not interfere. From January to June the gage at Monroe generally exceeds pool stage (13.3 feet), and minimum depths exceeding 7 feet are usual between the mouth of Black River and Camden, Ark., a distance of 351 miles. At intervals during this period the reading of the Camden gage exceeds 15 feet, and minimum depths of 7 feet may be expected between Camden and Arkadelphia. During the remainder of the year the pools furnished by the six dams, with moderate dredging in Black and Ouachita Rivers, provide depths of 6.5 feet between the mouth of Black River and Camden, Ark., and depths of only a few inches may be expected between Camden and Arkadelphia, Ark. At the end of the fiscal year project depth of 6.5 feet below mean low water was available between Camden, Ark., and the mouth of Black River. 'The total costs to the end of the fiscal year under the existing project were $4,574,551.31 for new work, $3,688,154.16 for main- tenance, and $5,125,274.75 for operating and care of locks and dams. Total expenditures were $13,368,387.28. In addition, the sum of $2,940,952.07 was expended between January 25, 1913, and June 30, 1936, on operating and care of the works of improvement under the provisions of the permanent indefinite appropriation for such purposes.

OUACHITA RIVER AND TRIBUTARIES, ARK. AND LA. Location. Ouachita River rises in Polk County, Ark., and flows about 600 miles in a general southeasterly and southerly direction through Arkansas and Louisiana. It is joined by Tensas and Little Rivers at Jonesville, La., below which place it is called Black River, and enters Red River 35.5 miles above its mouth. (See U. S. Geological Survey State maps and Mississippi River Commission Alluvial Valley quadrangle maps.) The Ouachita River Basin embraces about 25,000 square miles. Headwater streams drain about 3,500 square miles of rugged terrain of the Ouachita Mountains (including some 1,500 square miles of the Ouachita National Forest). Downstream the basin comprises about 21,500 square miles of hilly uplands and broad plains. Below Riverton, La., approximately 1,490 square miles are in the Red River backwater area. Existing project. The River and Harbor Act of May 17, 1950 (S. Doc. No. 117, 81st Cong., 1st sess.), approved the general plan for flood control on Ouachita River and tributaries, Arkan- sas and Louisiana, which provides for the construction of one multiple-purpose and one flood-control reservoir; protection works for three localities and channel improvement at several points. This act further authorized the incorporation into the general plan of the several separate existing projects for flood control along the Ouachita River and tributaries in the basin above the lower end of the levees on the east bank of Ouachita River.

HOMOCHITTO RIVER, MISS. Location. The project is located along the Homochitto River in Adams and Wilkinson Counties, Miss. (See Corps of Engi- neers, Mississippi River Commission alluvial valley maps and Artonish, Woodville, and Kingston quadrangles.) Existing project. The plan of improvement provides for the construction of a number of cut-offs, aggregating approximately 5.8 miles in length, which will reduce the length of the river from Rosetta, Miss., to its mouth from 37.7 miles to 30.6 miles; construction of small earth dams at points where the new cut- offs leave and reenter the existing channel; clearing and snagging operations along both banks from mile 1 to mile 35; and blasting along sides and bottom of the channel where its development is retarded by stumps or hard nonerodible clay strata. The project will result in clearing the river bed and banks of obstructions, shortening the channel, and producing a more uni- form slope, thereby resulting in faster run-off of floodwaters in the basin, minimizing the damages to crops and highways and making practicable more general use of farm and timber lands which have been hitherto subject to frequent extended inunda- tion.

This river rises in northwestern Arkansas and flows 690 miles, first north into Missouri, then southeasterly through Arkansas to the Mississippi River, 26 miles above Arkansas City, Ark. (See Mississippi River Commission alluvial valley maps, scale 1:62,500 and scale 1:500,000, for river from mouth to vicin- ity of Newport, Ark., and U. S. Geological Survey State map, scale 1:500,000.) The White River enters the Memphis district at the foot of Peach Orchard Bluff, Ark., flows 169 miles in a southeasterly direction to the Mississippi River, 4 miles north of Rosedale, Miss. Previous projects. Adopted by the River and Harbor Acts of March 3, 1871, June 23, 1874, August 14, 1876, June 14, 1880, July 5, 1884, and March 3, 1899. 895 896 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 For further details see page 1874, Annual Report for 1915, and page 938, Annual Report for 1938. Existing project. This provides for channel maintenance be- tween the mouth of the river and Batesville, 301 miles, by snag- ging and dredging and by contraction works. The stream has an ordinary freshet fluctuation of 15 feet throughout the portion covered by the project, and an extreme stage fluctuation of 60 feet at the mouth, and of 36 feet at Clarendon. This work has been prosecuted under annual estimates for maintenance by snagging and dredging. The latest (1950) approved estimate for-annual * cost of maintenance below Peach Orchard Bluff is $i5,000. The existing project was authorized by the following river and harbor act: Acts Work authorized Documents July 13, 1892 Open-channel work._-- - .-----..-----....... Annual Report, 1893, p. 2112. Terminal facilities. Railway spur tracks are available for transfer of freight between car and boat at Clarendon. There is a log slip for use of the owners only at Clarendon. Present facilities are considered adequate for existing commerce. Operations and results during fiscal year. All operations dur- ing the fiscal year 1951 were for maintenance by hired labor with Government plant. In snagging operations during the fiscal year 1951 the U. S. snag boat Tom Stallings operated over the river between the mouth and Peach Orchard Bluff, Ark., removing 202 snags. The cost and expenditures were $26,003.45. Condition at end of fiscal year. The project being for mainte- nance, completion is not contemplated. Snagging operations have materially improved the condition of the channel from the mouth to Peach Orchard Bluff (169 miles). This river is generally spoken of as navigable within the limits of this district (mouth to Peach Orchard Bluff) by boats of 3-foot draft at any time. Under ordinary conditions, boats of 6-foot draft may be taken to Peach Orchard Bluff from the first of February to the last of June. During the fiscal year ending June 30, 1951, depths were available on the White River which would permit navigation by vessels of 3-foot draft between the mouth and Peach Orchard Bluff (169 miles). The total costs and the total expenditures to June 30, 1951 were $1,360,578.97 for maintenance. Proposed operations. None. No work is scheduled for fiscal years 1952 and 1953.

WOLF RIVER (MEMPHIS HARBOR), TENN. Location. Wolf River rises in Benton County, Miss., and flows generally northwesterly about 100 miles, through Shelby County, Tenn., emptying into the Mississippi River within the corporate limits of the city of Memphis, Tenn. (See Mississippi River Com- mission alluvial valley maps, scale 1:62,500, and scale 1:500,000.) Previous projects. The River and Harbor Act of August 18, 1894, authorized dredging at the mouth of Wolf River as an item in the improvement of Memphis Harbor, the work being carried out under the supervision of the Mississippi River Commission. Existing project. This provides for a channel 9 feet deep at low water (71/2 feet below zero on the Memphis gage) from its mouth to Hindman Ferry Road (5.5 miles) with bottom widths of 250 feet from the mouth to Keel Avenue and 200 feet from Keel Avenue to North Second Street Road, and thence 125 feet wide from North Second Street Road to Hindman Ferry Road. The estimate of cost for new work, revised in 1935, is $1,185,- 000. The latest (1950) approved estimate of cost for annual main- tenance is $104,000. The work of improvement under the existing project up to North Second Street Road (3.5 miles) was authorized September 6, 1933, by the Public Works Administration, and the existing project was adopted by the River and Harbor Act approved August 30, 1935 (Rivers and Harbors Committee Does. 26, 72d Cong., 1st sess., and 45, 74th Cong., 1st sess.). Sketch maps are printed in the project documents. Local cooperation. The work under the existing project is subject to the condition that local interests shall furnish, free of cost to the United States, all rights-of-way required for channel enlargement and straightening, and suitable areas with retaining levees where needed for disposal of dredged material during initial construction and future maintenance as and when needed, and shall furnish assurances satisfactory to the Secretary of Army saving the United States free from damages resulting from the work. The work is also subject to the provision that no works shall be undertaken on any section of the channel through or above any bridge until such bridge has been altered in a manner satisfactory to the Secretary of Army, without cost to the United States. The conditions as pertaining to the improvement up to North Second Street Road have been complied with. Conditions above that point have not been complied with. 898 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Terminal facilities. There are 26 terminals operating in the port of Memphis, which comprises the upper 2 miles of Tennessee Chute, 2 miles of the Mississippi River upstream therefrom, and the lowermost 3 miles of Wolf River. Four terminals are operated by common carriers; 2 by contract carriers; and 20 are operated privately. Operations and results during fiscal year. Maintenance dredg- ing during the fiscal year of 1951 was conducted with leased plant. The dredge Burlington moved a total of 555,747 cubic yards of material in maintaining a channel of project dimensions. The total costs for the year were $91,620.81 and total expendi- tures were $93,067.55. Condition at end of fiscal year. The existing project was about 50 percent complete. At the end of the fiscal year ample depths existed in the channel below a point 900 feet above Hall Street. Project depth at low water is maintained in this reach by dredg- ing as required. From this point to beyond North Second Street Road depths of from 1 to 2 feet obtain during the low-water season. The work remaining to be done to complete the project is the extension of the channel from North Second Street Road to Hindman Ferry Road. Exclusive of maintenance dredging done during the fiscal year 1936 with Mississippi River funds which were included in the annual report of the Mississippi River Commission for that year under the caption "Dredges and dredging," the total costs to June 30, 1951, were $1,557,646.60, of which $586,500 were from Public Work funds for new work, $953,646.60 were from regular funds for maintenance, and, to cover the cost of retaining levees required of local interests, there have also been costs charged to contributed funds amounting to $17,500. The total expenditures from Federal funds were $1,540,146.60, the expenditures from contributed funds were $17,500. Proposed operations. An allocation of $95,000 will be applied on channel maintenance. The sum of $100,000 can be profitably expended during the fiscal year 1953 for maintenance dredging by leased plant from the mouth of Wolf River upstream to a point approximately 3,000 feet below the North Second Street Road.

The work covered by this project lies within and adjacent to the city of Memphis in Shelby County, Tenn., on the left bank of Wolf River and the right bank of Nonconnah Creek from the confluence of these streams with the Mississippi River upstream for approximate distances of 10 and 4 miles, respec- tively. (See U. S. Geological survey map of Tennessee, scale 1:500,000, and Mississippi River Commission alluvial valley maps, scale 1:62,500 and 1:500,000.) Existing project. The plan of improvement provides for the construction of a system (eight sections) of levees, flood walls, and bank protection, consisting of the following features: About 22,000 feet of earth levee and two concrete railroad floodgates along the right bank of Nonconnah Creek, extending from high ground near Tennessee Chute south of Riverside Park to high ground at Bodley Avenue east of Prospect Street; about 13,300 feet of concrete flood wall, about 2,300 feet of steel cellular wall and 31,500 feet of earth levee along the left bank of Wolf River, extending from downtown Memphis to high ground near Douglas Park; construction of six new pumping stations and eight storage reservoirs with appurtenant works for the disposal of interior drainage; and the construction of a culvert under North Bellevue Boulevard near Cypress Creek for the enlargement of the Cypress Creek Reservoir. The project will provide protection, with 3 feet FLOOD CONTROL-MEMPHIS, TENN., DISTRICT 901 free-board, for the city of Memphis and adjacent areas against a Mississippi River flood of 54.5 feet stage, or 4.1 feet higher than the maximum flood of record, which occurred in February 1937. The project was adopted by the Flood Control Act approved August 28, 1937, and so modified by the War Department Civil Appropriation Act approved June 28, 1939, that the cost of pro- viding pumping stations and outlet works for interior drainage shall be borne by the United States, and further, amended by the Flood Control Act approved July 24, 1946, to increase the total estimated cost of the project by $1,500,000. The current (1951) estimated cost of construction, is $13,430,000. Local cooperation. General assurances given by the city of Memphis and Shelby County, Tenn., were approved by the Secre- tary of War on August 2, 1938. All rights-of-way for the project have been provided by local interests with the exception of sec- tions 1 and 5. Section 1-D of section 1 has been furnished. Operations and results during the fiscal year. Planning and design were continued during the year for sections of the project not yet completed. Workhouse pumping station was completed, Marble Bayou pumping station is 58 percent complete and section 7 is 57 percent complete. The costs for the year were $537,185.76, and the expenditures were $589,852.66, all for new work. Condition at end of fiscal year. Sections 8, 6, 4, and 2 levees, Section 3 wall, Nonconnah Creek, Cypress Creek, May Street, Workhouse, and Fairfax pumping stations, and appurtenant works have been turned over to local interests for maintenance and operation. The total costs to June 30, 1951, were $7,302,723.04, and the total expenditures were $7,209,428.93, all for new work. Proposed operations. The unobligated balance June 30, 1951, of $87,646.68, plus an allotment of $750,000 for fiscal year 1952, totaling $837,646.68, will be applied as follows: New work: Continue detailed plans and design and specifications, in- cluding field investigations on remaining items........ $61,260.00 Completion of section 7 levee......... ................. 14,630.00 Completion of Marble Bayou pumping station.......... 33,220.00 Completion of section 1-D levee ....................... 17,391.00 Continue contract for construction of 1-C floodwall.... 711,145.68 Total for all work .................................. 837,646.68 Additional funds in the amount of $1,000,000 can be profitably expended in fiscal year 1953 to continue construction of section 1-C floodwall under continuing contract of fiscal year 1952. 902 REPORT OF CHIEF OF ENGINEERS, U.

FLOOD CONTROL WORK UNDER AUTHORITY OF SECTION 205 OF THE FLOOD CONTROL ACT APPROVED JUNE 30, 1948, AS AMENDED The Flood Control Act approved June 30, 1948, as amended by the Flood Control act approved May 17, 1950, authorized the allotment from flood control appropriations of not to exceed $2,- 000,000 for any one fiscal year to be expended for the accomplish- ment of small flood control projects that are urgently needed, fully justified, and non-controversial. The law sets a limitation of $150,000 to be expended in any one locality and indicates that the work shall be complete within itself. The sum of $100,000 was appropriated during fiscal year 1950 for work on Nixon Creek and its tributary Meridian Creek. Nixon Creek is a left-bank tributary of the South Fork of the Forked Deer River in West Tennessee. This work is being done by con- tract and is about 29 percent complete. Local interests have furnished the required assurances of local cooperation and have secured all of the necessary rights-of-way.

This is a consolidation of the old improvements of "Harbor at Sabine Pass and Port Arthur Canal" and "Sabine- Neches Canal, including Sabine River to Orange and Neches River to Beaumont, Texas." Sabine Pass is on the Gulf of Mexico, ap- proximately 58 miles east of Galveston and 280 miles west of Southwest Pass, Mississippi River. It connects Sabine Lake with the Gulf of Mexico. The Port Arthur Canal extends from near the upper end of Sabine Pass to the Port Arthur docks at the mouth of Taylors Bayou, a distance of 7 miles. Near its upper end, the Sabine-Neches Canal joins and extends to the mouth of the Neches and Sabine Rivers. The waterway next extends up 909 910 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 the Neches River to Beaumont and up the Sabine River to Orange. (See U. S. Coast and Geodetic Survey Charts Nos. 517 and 533.) Previous projects. The original project for improvement of Sabine Pass was adopted by River and Harbor Act of March 3, 1875, and subsequent projects and modifications by River and Harbor Acts of August 2, 1882, June 3, 1896, June 13, 1902, and June 19, 1906. The Port Arthur Canal was conveyed to the United States free of cost in 1906, and the River and Harbor Act of July 25, 1912, incorporated it in the project. The Sabine and Neches Rivers were first improved under the River and Harbor Acts of June 18, 1878, and March 3, 1899, and the Sabine-Neches Canal was first improved under the River and Harbor Acts of March 3, 1905, and March 2, 1907. The project was enlarged by the River and Harbor Acts of February 27, 1911, July 25, 1912, March 2, 1919, and September 22, 1922. For further details, see page 1863 of Annual Report for 1915 for the Sabine and Neches Rivers, Sabine Pass, and Port Arthur Canal, and page 985 of the report for 1916 for Sabine-Neches Canal. (See also pp. 1100 and 1105 of Annual Report for 1921 and p. 874 of Annual Report for 1926.) Existing project.

The project also provides for two stone jetties at the Sabine Pass entrance from the Gulf of Mexico, the western jetty to be RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 911 21,860 feet long and the eastern jetty to be 25,270 feet long. The project further provides for the removal of the guard lock in the Sabine-Neches Canal and the construction of suitable permanent protective works along the Sabine Lake frontage owned by the city of Port Arthur to prevent dredged material from entering Sabine Lake and to prevent the erosion of the material deposited. The mean tidal variation at the entrance is about 11/2 feet, at Port Arthur about 1 foot, and at Orange and Beaumont about five-tenths foot. Prolonged north winds during the winter season have depressed the water surface as much as 3.4 feet below mean low tide while tropical disturbances have caused heights as much as 7 feet above mean low tide. The estimate of cost for new work, exclusive of $385,500 con- tributed funds and value of useful work performed by local in- terests and of amounts expended on previous projects, is $15,- 368,700 (July 1951). The latest approved estimate for annual cost of maintenance is $809,000 (July 1951).

The existing project provides for a channel 12 feet deep at mean low water over a bottom width of 125 feet, with such passing places, widening at bends, locks or guard locks, and railway bridges over artificial cuts as are necessary from the Sabine River to Brownsville, Tex.; for the purchase or construc- tion of a 20-inch pipeline dredge; for the maintenance of a suit- able flood discharge channel in the Colorado River from Mata- gorda, Tex., to the Gulf of Mexico; for a tributary channel 9 feet deep and 100 feet wide in the San Bernard River, extending from the main channel to the State highway bridge some 31 miles above the mouth of the stream; for a tributary channel in the Colorado River 9 feet deep and 100 feet wide, extending from the main channel upstream a distance of 17 miles, with a turning basin of the same depth, 400 feet wide and 500 feet long at the head of the improvement; for a tributary channel 9 feet deep and 100 feet wide from Palacios, Tex., through Trespalacios and Matagorda Bays to the main channel; for a tributary channel 9 feet deep and 200 feet wide from the main channel to the harbor at Rockport, Tex., and improvement of that harbor to a depth of 9 feet; for rerouting the main channel along the north shore of Red Fish Bay between Aransas Bay and Corpus Christi Bay with no change in present authorized dimensions; for a tributary channel 12 feet deep and 100 feet wide from the main channel near Port Aransas, Tex., to the town of Aransas Pass, Tex., end- ing in a basin of the same depth, 300 feet wide and 2,200 feet long; for a tributary channel 6 feet deep and 60 feet wide from the main channel near Port O'Connor, Tex., into Barroom Bay; for a tributary channel 12 feet deep and 125 feet wide in Red Fish Bay from the main channel to Port Mansfield with a turning basin 400 feet by 600 feet and 12 feet deep at Port Mansfield; for a tributary channel 12 feet deep and 125 feet wide from the main channel to the vicinity of Harlingen, Tex., via the Arroyo Colorado with a turning basin 12 feet deep, 400 feet wide, and 500 feet long at the upper end; for side channels 12 feet deep and 125 feet wide and 6 feet deep and 60 feet wide leading from Laguna Madre around the south part of Port Isabel, Tex., a total length of 11/2 miles; for an alternate channel 12 feet deep and 125 feet wide across South Galveston Bay between Bolivar Peninsula and the Galveston Causeway; and for operating and care of the waterway. From the Sabine River (3 miles below Orange, Tex.) to the Port Arthur Canal, from Port Bolivar to the west end of Galveston Channel, from Port Aransas to Corpus Christi and from Port Isabel to Brownsville, Tex., the waterway 918 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 coincides with deep water channels improved and maintained under other projects. The mean tidal variation is 0.5 foot at Orange, 1 foot at Port Arthur, 1.3 feet in Galveston Bay, 1.5 feet at Freeport, 1 foot in Matagorda Bay, 1 foot at Corpus Christi, 1.5 feet at Port Isabel, and 1.5 feet at Brownsville. The extreme ranges of tide under ordinary conditions are 1 foot at Orange, 1.5 feet at Port Arthur, 2 feet in Galveston Bay, 2.0 feet at Freeport, 1.5 feet in Mata- gorda Bay, 1.5 feet at Corpus Christi, 2 feet at Port Isabel, and 1.5 feet at Brownsville. The height of tides is dependent largely on the wind. Strong north winds have depressed the water surface as much as 2 feet below mean low tide. The modified route of the main channel between Aransas Bay and Corpus Christi Bay is subject to the provision that no dredg- ing shall be done by the United States within 50 feet of any wharf or structure, the proposed drawbridge piers and fenders near Aransas Pass, 'Tex., being excepted from this provision. The tributary channel in the Colorado River is subject to the provision that no dredging shall be done by the United States within 50 feet of any wharf or structure excepting the highway bridge which crosses the river at mile 8.3. The tributary channel from Palacios, Tex., through Trespala- cios and Matagorda Bays, the tributary channel to Aransas Pass, Tex., and the tributary channel to Harlingen, Tex., are subject to the provision that no dredging shall be done by the United States within 50 feet of any wharf or structure. The estimate of cost of new work is $29,341,000 (July 1951) exclusive of amounts expended on previous projects. The latest approved estimate for annual cost of maintenance is $1,218,000, (July 1951) including $190,000 for operating and care of struc- tures.

GALVESTON HARBOR AND CHANNEL, TEX. Location. This is a consolidation of the authorized improve- ments at Galveston, Texas, which includes the projects formerly identified as Galveston Harbor, Tex., Galveston Channel, Tex.; and the Galveston seawall extension. The entrance to Galveston Harbor is located on the Gulf of Mexico, on the northern portion of the coast of Texas, 328 miles west of Southwest Pass on the Mississippi River and 278 miles northeast from the mouth of the Rio Grande. Galveston Channel extends from a point in Gal- veston Harbor between Bolivar Peninsula and Fort Point across the former inner bar to and along the wharf front of Galveston, and has a length of about 5 miles and a width of 1,200 feet. (See U. S. Coast and Geodetic Survey Chart No. 520.) Previous projects. The original project for the improvement of Galveston Harbor, Tex., was authorized by the River and Harbor Acts of June 23, 1874, June 14, 1880, and August 5, 1886. For further details see page 1854, Annual Report for 1915 and page 851, Annual Report for 1938. Existing project. The existing project provides for a channel 800 feet wide and 38 feet deep, from deep water in the Gulf of Mexico to a point between the jetties 2 miles west of the seaward end of the north jetty, thence 800 feet wide and 36 feet deep to Bolivar Roads; a channel 36 feet deep at mean low tide and 1,200 feet wide from Bolivar Roads (outer end of the old inner bar near Fort Point) to Forty-third Street, thence to Fifty-first Street with a width of 1,200 feet and 32 feet deep, in the city of Galveston, and for its extension to Fifty-seventh Street, to a depth of 32 feet and a width of 1,000 feet, when the interests of navigation and commerce require it; for two rubblestone jetties extending from Galveston Island (on the south) and Bolivar Peninsula (on the north) into the Gulf of Mexico (the south jetty being 35,900 feet long and the north jetty 25,907 feet long) ; the construction of 13 groins to protect the sea wall along the Gulf shore from about Twelfth to Sixty-first Street, Galveston, Tex.; for an exten- sion of the sea wall, which lies along the Gulf front of Galveston, from its angle at Sixth Street and Broadway to the south jetty, with protection at its junction with the south jetty, and for an ex- tension of the existing sea wall in a southwesterly direction from its present terminus near Sixty-first Street for a distance of ap- proximately 16,300 feet along the shore of the Gulf of Mexico. Under ordinary conditions, the mean tidal range in Galveston Harbor is 1.6 feet on the outer bar and 1.4 feet on the inner bar with extreme ranges of 2.3 and 2.1 feet, respectively. The mean tidal range in Galveston Channel is about 1.3 feet and the extreme range about 2 feet under ordinary conditions. The height of the tides in both Galveston Harbor and Channel is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimated Federal cost of new work, is $13,994,000.00 (July 1951); the estimated cost to local interests is $3,580,300; the total estimated cost is $17,574,300 (July 1951). The latest ap- 926 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 proved estimate for annual cost of maintenance of the project is $690,000 (July 1951).

Fully complied with except for the furnish- ing by local interests of assurances satisfactory to the Secretary of the Army that they will hold and save the United States free from claims for damages due to the construction and maintenance of the Galveston Channel portion of the project as modified by the River and Harbor Act of June 30, 1948. Terminal facilities. There are no terminals on Galveston Har- bor, but it is the entrance channel leading to extensive terminal RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 927 facilities located on Galveston Channel, 'Texas City Channel, and Houston Ship Channel. The terminal facilities on Galveston Channel are located almost entirely on the south side of the chan- nel. The principal wharves are owned by the city of Galveston and extend from Tenth Street to Forty-first Street. Reconstruc- tion of piers and transit sheds is in progress and timber bulk- heads and aprons are being replaced with steel bulkheads and concrete aprons and concrete slab decks at Piers 10, 34, 35, and 36 (code No. 958 - 917 - 915 - 912, Port Series No. 23, revised 1948.) Facilities are listed in the above Port Series and Port Series No. 6, Part 1, Corps of Engineers, and are considered ade- quate for existing commerce. Operationsand results during fiscal year.

TEXAS CITY CHANNEL, TEX. Location. Texas City is on the mainland of Texas on the west side of Galveston Bay, about 10 miles northwest of the city of Galveston. (See U. S. Coast and Geodetic Survey Charts Nos. 520 and 1282.) Previous projects. Adopted by River and Harbor Act approved March 3, 1899, and enlarged by River and Harbor Act approved June 25, 1910 (H. Doc. 328, 61st Cong., 2d sess.).. For further details see page 1856, Annual Report for 1915, and page 858 Annual Report for 1938. Existing project. This provides for a channel 36 feet deep at mean low tide and 400 feet wide on bottom from deep water in Galveston Harbor to the harbor at Texas City, a distance of about 61/2 miles, with a pile dike on its north side 28,200 feet long cov- ered with clay and other material dredged from the channel, with a harbor 1,000 feet wide on bottom and 36 feet deep at mean low tide extending approximately 4,250 feet to the southward of the south property line of the Monsanto Chemical Co., and for the construction of a rubble-mound dike a short distance south of the existing pile dike and extending between stations -1+600 (the shore) and 26+000, a distance of 27,600 feet. Under ordi- 930 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 nary conditions the mean tidal range is about 1.3 feet and the extreme range is about 2 feet. The height of tide is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimate of cost for new work is $3,210,000.00 (July 1951), exclusive of amounts expended on previous projects exclusive of $28,740 contributed by local interests. The latest approved estimate of cost of annual maintenance of the channel and dike is $211,500 (July 1951).

Local cooperation. Under the provisions of the River and Har- bor Acts of August 26, 1937, and June 30, 1948, local interests are required to furnish free of cost to the United States necessary rights-of-way and suitable spoil-disposal areas for new work and for subsequent maintenance as required and release the United States from claims for damages attributable to the work of im- provement and furnish assurance satisfactory to the Secretary of the Army that they will construct a common-carrier oil terminal substantially as proposed. None of these conditions have been complied with. All prior requirements have been fully complied with. Terminal facilities. Modern terminal facilities, privately owned, are located on the mainland at the inner end of this chan- nel and are considered adequate for existing commerce. (See Port Series, No. 23, revised 1948, Corps of Engineers.) A seatrain terminal, privately owned was completed in 1940. Operations and results during fiscal year. Maintenance: Peri- odic surveys and inspections were made at a cost of $5,799.95. The total expenditures were $5,819.71. Condition at end of fiscal year. The existing project was 72 percent complete. The work remaining consists of extending the turning basin 1,000 feet southward and enlarging the project, RIVERS AND HARBORS--GALVESTON, TEX., DISTRICT 931 including the turning basin extension, to a depth of 36 feet over a bottom width of 400 feet in the channel and 1,000 feet in the turning basin. The channel and the turning basin, except the authorized extension referred to above, were completed in 1937 to a depth of 34 feet over bottom widths of 300 feet and 800 feet, respectively. The pile dike was completed in 1915; the rubble- mound dike in 1934. The controlling depth in the channel was 30 feet, and in the completed portion of the turning basin was 28 feet at mean low tide. The total cost of the existing project to June 30, 1951, was as follows: New work Maintenance Total Regular funds.....................---------------------------------. $2,151,680. 52 $4,112,754. 24 $6,264,434.76 Public Works funds ..........------------------------------- 136,295. 78 ----------------.. 136,295. 78 Total United States funds......---------------------- 2,287,976. 30 4,112,754. 24 6,400,730. 54 ..

CHANNEL TO PORT BOLIVAR, TEX. Location. Port Bolivar is at the end of Bolivar Peninsula and 4 miles north of the city of Galveston. The channel connects. the 932 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 port with the channel in Galveston Harbor. (See U. S. Coast and Geodetic Survey Chart No. 520.) Previous projects. Adopted by the River and Harbor Act of March 2, 1907. For further details see page 1856, Annual Report for 1915, and page 860, Annual Report for 1938. Existing project. This provides for a channel 30 feet deep at mean low tide and 200 feet wide on bottom, beginning at deep water in Galveston Harbor and extending to a turning basin 1,600 feet long, with an average width of about 750 feet and 30 feet deep at mean low tide in front of the wharves. Under ordi- nary conditions the mean tidal range is about 1.3 feet and the extreme range about 2 feet. The height of tides is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimated cost of new work is $157,200 (July 1951), exclusive of amount expended on previous propects. The latest approved estimate for annual cost of maintenance of the channel and turning basin is $20,000 (July 1951), which provides for a depth of 20 feet in the channel and 20 feet in the turning basin, 500 feet square and an area 150 feet wide and 700 feet long in front of the highway ferry landing, these dimensions being suffi- cient to accommodate existing commerce. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents June 25, 1910 Excavation of a channel 30 feet deep and 200 feet H.

Doc. 1122, 65th Cong., 2d sess. crease width to about 750 feet. (Contains the latest published map.) Local cooperation. None required. Recommended modifications of project. Under date of June 24, 1926, the Chief of Engineers recommended that the project be curtailed by providing for a channel depth of 20 feet, 200 feet wide, with a turning basin of the same depth 500 feet square (H. Doc. 467, 69th Cong., 1st sess.). Terminal facilities. The terminals consist of two privately owned piers, one 400 feet wide by 1,200 feet long, and the other 210 feet wide by 1,200 feet long. These piers are not in use. A highway ferry landing owned by the State of Texas is located at the south end of the turning basin. The facilities are consid- ered adequate for existing commerce. Operations and results during fiscal year. Maintenance: From April 1-3, 1951, a total of 50,039 cubic yards of material was removed from 700 linear feet of channel, by contract, at a cost of $4,754.07. Periodic surveys and inspections were made at a cost of $672.15. The total cost for all work for the fiscal year was $5,426.22. The total expenditures were $5,426.22. Condition at end of fiscal year. The existing project was 54 percent complete. The channel, 200 feet wide, and turning basin, RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 933 1,000 feet square, were completed in 1912. The work remaining consists of enlarging the turning basin to project dimensions. Project dimensions have not been maintained in the completed part since lesser dimensions are adequate for existing commerce. The controlling depths at mean low tide over usable widths were 20 feet in the channel, 7 feet in the turning basin at en- trance to slip No. 3, and 22.8 feet in the channel to the new ferry landing. The total cost of the existing project to June 30, 1951, was $681,857.37, of which $85,213.85 was for new work and $596,- 643.52 was for maintenance. The total expenditures were $681,- 857.37. Proposed operations. The balance unexpended at the end of the fiscal year, amounting to $3,673.78, will be applied to condition surveys and upkeep of reference lines during fiscal year 1952. The sum of $13,500 can be profitably expended for mainte- nance dredging of a portion of the channel leading to the high- way ferry landing, by contract (February 1953).

HOUSTON SHIP CHANNEL, TEX. Location. The channel connects Galveston Harbor, at a point opposite Port Bolivar, with the city of Houston, Tex., extending 50 miles in a northwesterly direction across Galveston Bay through the San Jacinto River and Buffalo Bayou to a turning basin at the head of Long Reach with a light-draft channel 7 miles long from the turning basin to Main Street, Houston. (See U. S. Coast and Geodetic Survey Charts Nos. 1282 and 532.) Previous projects. Authorized by River and Harbor Act of June 10, 1872, modified in 1877, and by River and Harbor Acts of March 3, 1879; March 3, 1899; February 20, 1900; March 3, 1905; and March 4, 1913. For further details see page 1856 of the Annual Report for 1915 and page 862 of the Annual Report for 1938. Existing project. This provides for a channel 36 feet deep at mean low tide from deep water in Galveston Bay to and includ- ing the Houston turning basin, with a width of 400 feet from Bolivar Roads to 5,000 feet above Baytown, thence 350 feet to the 934 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 mouth of Boggy Bayou, thence 300 feet to the Houston turning basin (about 1,000 feet wide) ; for turning points at the mouth of Hunting Bayou and at the lower end of Brady Island; for such off-channel silting basins on any part of the waterway as the Chief of Engineers may consider advisable; and for suitable widening of the bends at Lynchburg, Norsworthy, Manchester, and Harrisburg. The project also provides for suitable widening of the channel in front of the navigation district's wharf at Man- chester; for certain cut-offs and easing of sharp bends; for con- struction of a dike 26,000 feet long to protect the channel in upper Galveston Bay; for a light-draft extension of the channel 10 feet deep at mean low tide and 60 feet wide, without easing the bends, through Buffalo Bayou from the turning basin to the mouth of White Oak Bayou in Houston, Tex.; and for a branch channel 10 feet deep at mean low tide and 60 feet wide in the old channel of Buffalo Bayou behind Brady Island. The mean tidal range under ordinary conditions is 0.6 foot to 1.3 feet in the lower part of Galveston Bay; 0.6 foot to 1.3 feet in the upper bay; and 0.5 foot to 1 foot in the San Jacinto River and Buffalo Bayou. The extreme ranges under ordinary conditions are about 2 feet, 1.2 feet, and 1 foot, respectively. Freshets sometimes cause rises of over 12 feet in Buffalo Bayou. The height of the tides, however, is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be de- pressed 2 feet below mean low tide. The estimate of cost for new work is $17,059,000 (July 1951), exclusive of amounts expended on previous projects, and exclusive of $1,365,000 contributed by local interests. The latest approved estimate for annual cost of maintenance is $918,000 (July 1951).

Coast and Geodetic Survey Chart No. 1282.) Existing project. The existing project provides for a channel 6 feet deep at mean low tide and 100 feet wide through the bar at the mouth of Double Bayou. Under ordinary conditions the mean tidal range is about 0.5 foot and the extreme range is about 1.2 feet. The height of tides is dependent largely on the wind, and, during strong "northers" in the winter season, the water surface may be depressed 11/2 feet below mean low tide. 'The latest approved estimate for annual cost of maintenance is $10,000 (July 1951). The existing project was authorized by the River and Harbor Act approved March 3, 1899 (H. Doc. 387, 55th Cong., 2d sess.). The latest published map is contained in the project document. Local cooperation. None required. Terminal facilities. The terminal facilities on this waterway are confined to small wharves for local use and an oil dock. They are considered adequate for the present commerce. Operations and results during fiscal year. Maintenance: A total of 90,761 cubic yards of material was removed by contract during the period June 16-29, 1951, from 6,100 linear feet of channel at a cost of $18,264.94. Periodic surveys and inspections were made at a cost of $241.76. The total cost during the fiscal year was $18,506.70. The total expenditures were $2,701.36. Condition at end of fiscal year. The existing project was com- pleted in 1941. The controlling depth was 6 feet at mean low tide. The total cost of the existing project to June 30, 1951, was $215,165.17, of which $10,309.75 was for new work and $204,- 855.42 was for maintenance.

ANAHUAC CHANNEL, TEX. Location. The- town of Anahuac is on the northeast side of upper Galveston or Trinity Bay, opposite the mouth of the Trinity River, 38 miles north of Galveston and 25 miles northeast of Sea- brook. (See U. S. Coast and Geodetic Survey Chart No. 1282.) Existing project. There is no definite project for this channel. The River and Harbor Act approved March 3, 1905, contained an item for "Improving West Galveston Bay Channel, Double Bayou, and mouths of adjacent streams, including Trinity River, Anahuac Channel, and Cedar Bayou," but at the time of the appropriation no recommendation of definite channel dimensions had been made to Congress. A channel 6 feet deep at mean low tide and 80 feet wide was dredged in 1905 from Galveston Bay to the wharves at Anahuac, a distance of 16,000 feet. Under ordinary conditions the meafi tidal range is about 0.75 foot and the extreme range is about 1.2 feet. The height of tide is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 11/2 feet below mean low tide. The latest approved estimate for annual cost of maintenance is $35,000 (July 1951). The latest publised map is contained in House Document No. 440, Fifty-sixth Congress, first session. Local cooperation. None required. Terminal facilities. The terminal facilities are at Anahuac and consist of several small privately owned wharves and slips for local use. They are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Peri- odic surveys and inspections were made at a cost of $153.61. A total of 91,056 cubic yards of material was removed by contract during the period April 27 to May 18, 1951, from 5,800 linear feet of channel at a cost of $19,115.91. The total cost for the fiscal year was $19,269.52. The total expenditures was $19,- 223.90. Condition at end of fiscal year. The existing project was com- pleted in 1911. The controlling depth was 6 feet at mean low tide. The total cost of the existing project to June 30, 1951, was $532,033.25 of which $5,975.10 was for new work and $526,- 058.15 was for maintenance. The total expenditures were $531,- 987.63. 940 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Proposed operations.

TRINITY RIVER AND TRIBUTARIES, TEX. Location. This river rises in north-central Texas and flows southeasterly about 760 miles, discharging into Galveston Bay, 37 miles northeasterly from Galveston (U. S. Geological Survey base map, Texas, scale 1:500,000). Previous projects. The project outlined in House Document No. 409, Fifty-sixth Congress, first session, was adopted in part by the River and Harbor Acts of June 13, 1902, March 3, 1905, March 2, 1907, June 25, 1910, July 25, 1912, March 4, 1913, and July 27, 1916, each of which acts authorized the construction of certain-named locks and dams. The portion of the project relating to locks and dams construction was abandoned by the River and Harbor Act of September 22, 1922. For further details see page 1113 of Annual Report for 1921, and page 986 of Annual Report for 1932. Existing project. With abandonment of the lock and dam con- struction, the improvement of the Trinity River by a channel 6 feet deep and of navigable width from the mouth to Liberty (river mile 41.4) was left as the existing project, being continued as provided for in the River and Harbor Act of July 25, 1912. The existing project was modified by the River and Harbor Act of March 2, 1945, which approved a comprehensive plan of develop- ment of the Trinity River and tributaries, Tex., in accordance with the recommendations set forth in House Document No. 403, Seventy-seventh Congress, first session, subject to such future modifications as in the discretion of the Chief of Engineers and RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 941 the Secretary of the Army may be advisable. That comprehensive plan of development provided for a navigable channel from a point in Galveston Bay at the Houston Ship Channel to a terminus at Fort Worth, Tex. Such navigable channel was to be not less than 9 feet in depth, and to have a minimum bottom width of 200 feet in Galveston Bay and 150 feet in the river section on tangents, with shunting places and suitable widening on curves, and with a turning basin at Liberty. The navigation locks would have clear inside dimensions of 75 feet by 400 feet. The 1945 act, however, authorized for construction at this time only that portion of the channel as far upstream as Liberty, Tex. The River and Harbor Act of July 24, 1946, further modified the comprehensive plan for the Trinity River Basin development so as to locate the section of the navigation channel below Ana- huac nearer the eastern shore of Trinity Bay, in accordance with the recommendations of the Chief of Engineers in House Docu- ment No. 634, Seventy-ninth Congress, second session. This modi- fication provides for a navigation channel 9 feet deep and 150 feet wide from the Houston Ship Channel near Red Fish Reef along the easterly shore of Galveston Bay with a protective em- bankment to the mouth of the Trinity River near Anahuac, thence by way of a lateral canal of the same dimensions along the east side of the Trinity River to a turning basin near Liberty; and for cutoffs, pumping plant, siphons, intake structures, and alterations to highway bridges and utilities. The estimated federal cost of this portion of the comprehensive plan below Liberty is $7,750,000 (July 1949), exclusive of amounts expended on previous projects. The latest approved esti- mate for annual cost of maintenance and operation is $120,000 (July 1951). The latest published maps are contained in House Document No. 634, Seventy-ninth Congress. The estimated first cost to the United States of the approved comprehensive plan for canalization to Fort Worth is $96,000,000 (1939 prices), with $1,760,000 annually for maintenance and operation. Under ordinary conditions the mean tidal range in the bay is from about 0.6 foot to about 1.2 feet. The height of tide is de- pendent largely on the wind, and during strong northerly winds in the winter season the water surface may be depressed 1.5 feet below mean low tide. Local cooperation. The work recommended in House Docu- ment 403, Seventy-seventh Congress, is authorized subject to the conditions that local interests furnish necessary rights-of-way, suitable areas for disposal of dredged material, and make neces- sary changes in utilities crossing the natural river channel below Liberty; and give assurances satisfactory to the Secretary of the Army that they will provide adequate terminal and transfer fa- cilities on the waterway, and hold and save the United States free from claims for damages that may result from construction and operation of the improvements. Local interests have fully com- plied with conditions contained in House Document No. 634, Seventy-ninth Congress, second session, and have furnished assur- 942 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 ances, accepted by the Secretary of the Army February 9, 1949, that they will comply with the requirements set forth in House Document No. 403, Seventy-seventh Congress, first session for the channel between Anahuac and Liberty. All local cooperation for the project below Anahuac, Tex., has been complied with. Terminal facilities. The only wharves on this river are all in the first 20 miles above the mouth. They are four in number and range from 10 to 20 feet in length. All are privately owned, and usage is free at all except one. One has a hand derrick; the other three have no freight-handling facilities. They have no physical connection with any railroad. They are adequate for the existing commerce, and there is ample room for future enlargement. Operations and results during fiscal year. New work: A total of 690,573 cubic yards of material was removed by contract from 7,900 linear feet of channel and 13,567 cubic yards of material were placed in a protective embankment during the period July 1 -30, 1950, at a cost of $84,034.01. In addition, office studies and the preparation of a plan of construction between Anahuac and Liberty, Tex., were continued, and engineering and design work was accomplished at a cost of $21,965.55. Maintenance: Periodic surveys and inspections were made at a cost of $483.63. A total of 40,043 cubic yards of material was removed by contract from mile 9.9 to mile 10.3 during the period May 19-29, 1951, at a cost of $10,720.34. The total cost during the fiscal year was $117,203.53, of which $105,999.56 was for new work and $11,203.97 was for mainte- nance. The total expenditures were $218,541.48. Condition at end of fiscal year. The navigation channel below Liberty, Tex., is 13 percent complete. The original project,.was completed in 1925. The channel from its junction with the Houston Ship Channel to a point 1 mile below Anahuac, Tex., has been dredged to a depth of 9 feet below mean low tide over a bottom width of 150 feet. The controlling depth between the Houston Ship Channel and a point 1 mile below Anahuac, Tex., was 9.5 feet at mean low tide. The controlling depth between the mouth of the Trinity River and river mile 28.5 was 7.5 feet, and 3 feet thence to Liberty. Authorized construction remaining under the comprehensive plan consists of completing that portion of the navigation channel from 1 mile below Anahuac to Liberty, Tex., with cutoffs, pumping plant, siphons, intake structures, and al- terations to highway bridges and utilities. The total cost of the existing project to June 30, 1951, was $1,198,650.93 of which $1,034,552.16 was for new work and $164,098.77 was for mainte- nance. The total expenditures were $1,198,688.35. Proposed operations. The balance unexpended at the end of the fiscal year, amounting to $15,375.33, plus accounts receivable of $42.42, together with an allotment of $3,600.00 for the fiscal year 1952, a total of $19,017.75, will be applied as follows: RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 943 Accounts payable June 30, 1951............................... $5.00 New work: Surveys, tests, and engineering studies by hired labor, (July 1951-June 1952) .............................. 14,633.09 Maintenance: Establishment of permanent reference line and surveys to determine condition of the channel (July 1951- June 1952) ............................................ 4,379.66 Total for all work .................................... 19,017.75 The sum of $16,800 can be profitably expended during the fiscal year 1953 for maintenance dredging of shoaled reaches in Trinity River above Anahuac, by contract (February 1953).

CEDAR BAYOU, TEX. Location. This bayou is about 30 miles long. It flows to the south and empties into the northwest corner of upper Galveston Bay, about 11/2 miles below the mouth of San Jacinto River and about 281/2 miles north of Galveston, Tex. (See U. S. Coast and Geodetic Survey Chart No. 1282.) Previous projects. Adopted by the River and Harbor Acts of September 19, 1890, and July 13, 1892. For further details see page 869, Annual Report for 1938. Existing project. This provides for a channel 10 feet deep at mean low tide and 100 feet wide from the Houston Ship Channel to a point on the bayou, 11 miles above the mouth. The project also includes the jetties at the mouth of the bayou provided for under the previous project. Under ordinary conditions the mean tidal range is about 0.6 foot and the extreme range 1.2 feet. The height of tides is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be de- pressed 2 feet below mean low tide. The estimate of cost for new work is $42,000 (July 1951), exclusive of amounts expended on previous projects, and $25,000 to be contributed by local interests. The latest approved estimate for annual cost of maintenance is $20,000 (July 1951). 944 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 The existing project was adopted by the River and Harbor Act of July 3, 1930 (S. Doc. 107, 71st Cong., 2d sess.). The latest published map is in this document. Local cooperation. The River and Harbor Act, approved July 3, 1930, provides that local interests shall contribute 50 percent of the estimated first cost of the improvement, but not to exceed $25,000, and shall furnish, without cost to the United States, all necessary easements, rights-of-way, and dumping grounds. These conditions have not been completely met, but local inter- ests have complied with all the necessary requirements to complete the channel to the first bend in Cedar Bayou above the mouth. Terminal facilities. The terminal facilities consist of a few small wharves, privately owned, for local use located at various places along Cedar Bayou, an oil-loading wharf owned by the Atlantic Pipe Line Co. located one-half mile above the mouth of the bayou, and an oil-loading wharf owned by the Sinclair-Prairie Oil Co. located 11 miles above the mouth of the bayou. The present facilities are considered adequate for existing commerce. Operations and results during fiscal year. Maintenance: Peri- odic surveys and inspections were made at a cost of $34.31. A total of 299,700 cubic yards of material was removed from 18,000 linear feet of channel by contract during the period from Febru- ary 7 to March 26, 1951, at a cost of $51,584.12. The total cost for the fiscal year was $51,618.43. The total expenditures were $51,618.43. Condition at end of fiscal year. The existing project was about 37 percent complete. The channel was completed in 1931 to project dimensions from the Houston Ship Channel to the first bend in Cedar Bayou above the mouth. Two brush and stone jetties have been constructed at the mouth of Cedar Bayou. Work remaining consists of dredging the channel to project dimensions from the first bend above the mouth to point 11 miles above the mouth. The controlling depths at mean low tide were 10.0 feet from Houston Ship Channel to the first bend in Cedar Bayou above the mouth and 6.0 feet thence to a point in the bayou 11 miles above the mouth. The total cost of the existing project to June 30, 1951, was as follows: New work Maintenance Total Regular funds.. .-........... ------ ___------ $12,575.56 $311,299.31 $323,874.87 Contributed funds....--- ---------------------------- 12,575. 57 12,575. 57 Total ....--.....-------------------- __... 25,151.13 --------............ 311,299.31 336,450. 44 The total expenditures were $336,450.44, consisting of $323,- 874.87 from regular funds and $12,575.57 from contributed funds for new work.

CLEAR CREEK AND CLEAR LAKE, TEX. Location. Clear Creek has its source about 13 miles south of Houston, Tex., and flows southeast for a distance of about 25 miles, emptying into the west side of upper Galveston Bay at a point 24 miles northwest of Galveston, Tex. (See U. S. Coast and Geodetic Survey Chart No. 1282.) Existing project. This provides for a channel 7 feet deep at mean low tide and 75 feet wide from deep water in Galveston Bay to a new entrance to Clear Creek, and a channel 7 feet deep and 60 feet wide in Clear Creek and Clear Lake to the county highway bridge at League City. Under ordinary conditions the mean tidal range is about 0.8 foot and the extreme range is 1.4 feet. The height of tides is dependent largely on the wind and during strong "northers" in the winter season the water surface may be de- pressed 2 feet below mean low tide. The latest approved estimate for annual cost of maintenance is $10,000 (July 1951).

DICKINSON BAYOU, TEX. Location. This bayou enters Galveston Bay on the west side about 20 miles northwest of Galveston. (See U. S. Coast and Geo- detic Survey Chart No. 1282.) Existing project. This provides for a channel 6 feet deep at mean low tide and 60 feet wide along the present route from the natural 6-foot depth in Galveston Bay through Dickinson Bay and Dickinson Bayou to the Galveston, Houston & Henderson Rail- road bridge at Dickinson, Tex. Under ordinary conditions the mean tidal range is about 1 foot and the extreme range about 1.4 feet. The height of tides is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 21/2 feet below mean low tide. The latest approved estimate for annual cost of maintenance is $12,500 (July 1951). Authority for the original dimensions (4 by 50 feet) of this channel is explained in the Annual Report for 1931, page 1093. The River and Harbor Act approved June 20, 1938, authorized the present project dimensions (H. Doc. 568, 75th Cong., 3d sess.). The latest published map is in this document.

CHOCOLATE BAYOU, TEX. Location. The source of the bayou is about 25 miles southwest of Houston and the mouth is in Chocolate Bay, an arm of West Galveston Bay, about 12 miles north of San Luis Pass and 28 miles west of Galveston. It is tidal throughout its length, and the lowest stages occur during the winter season. The authorized section extends from the Gulf Intracoastal Waterway through Chocolate Bay to the mouth of the bayou, a distance of about 5.6 miles. Existing project. The existing project, adopted by the River and Harbor Act approved March 2, 1907 (H. Doc. 445, 56th Cong., 1st sess.), modified by the River and Harbor Act approved March 2, 1945 (H. Doc. 337, 76th Cong., 1st sess.), and further modified by the River and Harbor Act approved May 17, 1950 (H. Doc. 768, 80th Cong., 2d sess.), provides for a channel 4 feet deep at mean low tide and 100 feet wide through Chocolate Bay to the extent necessary to afford a connection between Chocolate Bayou and the Gulf Intracoastal Waterway. Under ordinary con- ditions the mean tidal range is about 1 foot and the extreme range about 11/2 feet. The height of tide is largely dependent on the 948 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 force and direction of the wind and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimate of cost of new work is $54,500 (July 1951). The latest approved estimate for annual cost of maintenance is $9,- 600 (July 1951). The latest published map is contained in House Document No. 768, Eightieth Congress, Second Session. Local cooperation. None required. Terminal facilities. The terminal facilities consist of small privately owned wharves located at various points along the bayou. They are considered adequate for existing commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. The existing project was 12 percent complete. The controlling depth of the channel from its confluence with the Gulf Intracoastal Waterway through Choco- late Bay to the mouth of the Bayou was 6 feet at mean low tide over a bottom width of 60 feet. The total cost of the existing project to June 30, 1951, was $71,097.40 of which $6,512.12 was for new work and $64,585.28 was for maintenance. The total expenditures were $71,097.40, all from regular funds. Proposed operations. No work is scheduled for fiscal year 1952. The sum of $750 can be profitably expended during fiscal year 1953 for surveys to determine channel conditions and for refer- ence line maintenance.

FREEPORT HARBOR, TEX. Location. This harbor is formed by the improvement of the Brazos River, Tex., from the mouth to Freeport, about 6 miles above. (See U. S. Coast and Geodetic Survey Chart No. 525.) The mouth of the Brazos River is about 47 miles southwest of Galveston Harbor .entrance and about 137 miles northeast of Aransas Pass (Port Aransas). Previous projects. Authorized by River and Harbor Act of June 14, 1880. For further details see page 1860 of annual report for 1915, and page 872 of annual report for 1938. RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 949 Existing project. This provides for a project depth of 38 feet at mean low tide in the outer bar channel from that depth in the Gulf of Mexico to a point within the jetties; thence 36 feet in the authorized channels and basins to and including the upper turn- ing basin about one-half mile below the Stauffer Chemical Co. plant, with two turning basins, one 700 by 700 feet at Brazosport and one 600 by 600 feet at the upper end of the channel, the channel to have a width of 300 feet seaward of the jettied en- trance, 200 feet from the jettied entrance to the Brazosport turn- ing basin, widened at the bend, and averaging 375 feet, thence to the upper turning basin; the widths in the approaches to the turning basins to converge within a distance of 800 feet from the width of the turning basin to the width of the channel; and for the extension of the channel with a depth of 30 feet and a width of 200 feet to and including the turning basin near the Stauffer Chemical Co. plant at Freeport, when required in the interests of commerce and navigation. The work is to be accomplished as may be found desirable, by dredging, by jetties at the mouth of the harbor, and by a diversion dam in the Brazos River, a di- version channel, and necessary auxiliary works in general ac- cordance with plan No. 6, as proposed by the district engineer, together with a lock in the diversion dam, approximately 200 feet long, 55 feet wide and 121/ feet deep over the miter sills. The River and Harbor Act of July 3, 1930, modified the act of March 3, 1925, so as to provide that when local interests shall have furnished assurances satisfactory to the Secretary of the Army that they will maintain the diversion channel, the United States shall assume the cost of maintenance of the navigable channel, estimated at $75,000 annually, including care and opera- tion of the lock, if provided (Rivers and Harbors Committee Doc. 18, 70th Cong., 1st sess.). Under ordinary conditions the mean tidal range is about 1.5 feet and the extreme range about 21/ feet. Freshets in the river, except under extreme conditions, do not cause a greater variation in the water surface than the tidal action. The estimated cost of new work is $1,633,000 (July 1951), ex- clusive of $758,302.79 contributed funds and $565,697.21 remain- ing to be contributed by local interests upon request. The latest approved estimate of cost of annual maintenance is $184,000 (July 1951). The existing project was authorized by the following river and harbor acts: 950 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Acts Work authorized Documents Mar. 3, 1899 Dredging and such other work as may be deemed Specified in act. most effective in the judgment of the Secretary of War in improving and developing the harbor; for taking over the jetties and other privately built works at the mouth of the river.

Other facilities privately owned are one sulfur-loading dock, two oil docks, an acid dock, and two shell unloading docks. The present facilities are considered ade- quate for existing commerce. Operations and results during fiscal year. Maintenance: Peri- odic surveys and inspections were made at a cost of $9,920.02. Detail hydrographic surveys of sea bar and jetty channels were made at a cost of $1,483.78. Final surveys and inspections were made on dredging between Quintana Point and the Brazosport turning basins by contract at a cost of $580.43. The Government hopper dredge Biddle removed 684,227 cubic yards of material from the sea bar and jetty channels during the periods July 16 to August 5 and August 12 to September 2, 1950, at a cost of $132,182.18. The total cost of work for the fiscal year was $144,- 166.41. The total expenditures were $241,776.13. Condition at end of fiscal year. The existing project was 69 percent complete. The work remaining consists of deepening the channel to and including the turning basin near the Stauffer Chemical Co. plant and constructing a lock in the diversion dam RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 951 in the old Brazos River. The controlling depths at mean low tide in the various channels and turning basins were as follows: Channel from deep water in the Gulf of Mexico to seaward end of jetty 31.0 feet; channel from seaward end of jetty to Brazos- port turning basin, 30.0; Brazosport turning basin, 34 feet; channel from Brazosport turning basin to upper turning basin, 30.0; upper turning basin, 30 feet; channel from upper turn- ing basin to turning basin at Stauffer Chemical Co. plant, 19 feet, and the turning basin at the Stauffer Chemical Co. plant, 20 feet.

CHANNEL FROM PASS CAVALLO TO PORT LAVACA, TEX. Location. The bar at Pass Cavallo is 125 miles southwest of Galveston entrance and 54 miles north of Aransas Pass. Port Lavaca lies 26 miles to the northwest of the pass, across Mata- gorda and Lavaca Bays. (See U. S. Coast and Geodetic Chart No. 1117.) Existing project. This provides for a depth of 9 feet and a width of 100 feet from Lynns Bayou at Port Lavaca, Tex., to deep water in Matagorda Bay near Port O'Connor, Tex., a distance of about 11 miles; for channel 6 feet deep and 100 feet wide from Port Lavaca via Lavaca Bay, Lavaca, and Navidad Rivers to Red Bluff about mile 3 on the Navidad River, a total distance of 20 miles; and for a harbor of refuge 9 feet deep near Port Lavaca with an approach channel 9 feet deep and 100 feet wide. Under ordinary conditions the mean tidal range is about 1 foot and the extreme range about 2 feet. The height of tide is dependent largely on the wind, and during strong "northers" in the winter season the water surface may be depressed 2 feet below mean low tide. The estimate of cost for new work, is $460,500 (July 1951). The latest approved estimate of cost for annual maintenance is $58,000 (July 1951).

RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 953 Local cooperation. Under the River and Harbor Act of March 2, 1945, local interests are required to furnish free of cost to the United States all necessary lands, easements, and rights-of-way, and suitable spoil-disposal areas for the initial construction and subsequent maintenance when and as required; hold and save the United States free from damages that may result from the con- struction and maintenance of the project; and provide necessary mooring facilities to which all vessels shall have free and equal access during storm periods, none of which has been complied with. Requirements under prior acts have been complied with. Terminal facilities. The terminal facilities consist of several privately owned piers and three privately owned slips at Port Lavaca, and a municipally owned wharf, turning basin, one oil dock, and refrigerated sea-food processing and packing plant at the mouth of Lynns Bayou. The municipally owned facilities are open to the general public and are adequate for existing commerce. In addition, there is a privately owned channel, turn- ing basin with private wharves, oil dock, and loading facilities owned by Aluminum Co. of America at Point Comfort, Tex. Operations and results during fiscal year. Maintenance: Peri- odic surveys and inspections were made at a cost of $1,438.12. The total expenditures were $1,435.68. Condition at end of fiscal year. The existing project was 27 percent complete. The channel from the 9-foot contour in Mata- gorda Bay to the mouth of Lynns Bayou was completed in 1939. The work remaining consists of dredging the channel through Lavaca Bay and the Lavaca and Navidad Rivers to Red Bluff on the Navidad River and dredging the harbor of refuge at Port Lavaca. The controlling depth at mean low water in the com- pleted channel was 8.7 feet. The total cost of the existing project to June 30, 1951, was $446,571.33, of which $125,494.49 was for new work and $321,076.84 was for maintenance. The total expen- ditures were $446,568.89. Proposed operations. The balance unexpended at the end of the fiscal year, amounting to $64.32, together with an allotment of $1,800 for the fiscal year 1952, a total of $1,864.32, will be applied to surveys to determine channel conditions and for reference line maintenance. The sum of $1,800 can be profitably expended during the fiscal year 1953 for maintenance consisting of surveys to determine channel conditions. 954 REPORT OF CHIEF OF ENGINEERS, U. S.

GUADALUPE RIVER, TEX. Location. This river has its source in southwestern Texas, approximately 32 miles south of Junction, Tex., flows in a south- easterly direction a distance of about 458 river miles and empties into the head of San Antonio Bay, 60 miles northeast of Corpus Christi and 140 miles southwest of Galveston. (See U. S. Coast and Geodetic Survey Chart No. 1285.) Previous project. Authorized in the River and Harbor Act approved March 2, 1907. For further details see page 1102 of the Annual Report for 1922. Existing project. The plan of improvement provides for a navigation channel 9 feet deep and 100 feet wide extending about 45.5 miles from the Gulf Intracoastal Waterway by way of Sea- drift to a point on the Guadalupe River 3 miles above Victoria, Tex. Under ordinary conditions the mean tidal range is about 1 foot and the extreme range is about 11/2 feet. The height of tide is dependent largely upon the strength and direction of winds. During strong north winds in the winter season the water surface is occasionally depressed 1 foot below mean low tide. In the river section the ordinary fluctuation is about 2 feet and the extreme fluctuation due to floods about 20 feet. The estimated Federal cost for construction is $13,400,000 (July 1951) ; the cost to local interests for lands and damages and relocations is $1,066,000, (1945), a total of $14,466,000 (July 1951). The latest approved estimate for annual cost of operating and maintenance is $82,000 (July 1951). The existing project was authorized in the River and Harbor Act approved March 2, 1945 (H. Doc. 247, 76th Cong., 1st sess.) The latest publised map is in the project document. Local cooperation. 'The navigation features of the project were authorized subject to the provisions that local interests furnish free of cost to the United States all lands, easements, rights-of- way, and spoil-disposal areas for construction and for subsequent maintenance as required, hold and save the United States free RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 955 from all claims for damages that may result from the construc- tion and maintenance of the channel, bear all costs of required bridge modification and give assurances satisfactory to the Secre- tary of the Army that they will provide adequate terminal facili- ties, including turning basins at Seadrift and Victoria, none of which has been complied with. Terminal facilities. Terminal facilities consist of small wharves located at Seadrift and other locations along the river. These facilities are privately owned but are used to some extent by the public on equal terms. They are considered adequate for existing commerce. Recommended modification of project. Under date of Decem- ber 22, 1949, the Chief of Engineers recommended modification of the existing project to provide a basin for a harbor of refuge for small craft at Seadrift 9 feet deep at mean low water, 200 feet wide, and 1,000 feet long with an entrance channel 9 feet deep and 100 feet wide from the authorized side channel to Seadrift, and surrounded by a protective levee with its top at elevation 20, with such modifications thereof as in the discretion of the Chief of Engineers may be advisable at an estimated cost to the United States of $52,000 for construction and $1,200 annually for mainte- nance in addition to that now required. (H. D. 478, 81st Cong., 2d sess.) Operations and results during fiscal year. Operations during the fiscal year consisted of field surveys and office studies neces- sary for preparation of the definite project report. Total cost during the fiscal year was $21,409.74, all for new work from regular funds by hired labor. Conditions at end of fiscal year. A channel 5 feet deep by 40 feet wide from deep water in San Antonio Bay to Victoria, Tex., was completed in 1912. The controlling depth at mean low tide in the channel across San Antonio Bay is about 2 feet. Navigation in the river is impossible due to logs, snags, and shoals. Modification of the channel to Victoria was 2 percent complete. Preliminary studies, subsurface investigations, and design for preparation of detailed plans was 99 percent complete. Total cost under the existing project to June 30, 1951, was $199,885.75 all for new work from regular funds by hired labor. Total expenditures were $199,833.00. Proposed operations. No work is scheduled for the fiscal year 1952. The sum of $40,000 can be profitably expended during the fiscal year 1953 for preparation of preconstruction engineering and survey work including preparation of plans and specifications covering Federal items of construction. 956 REPORT OF CHIEF OF ENGINEERS, U.

LITTLE BAY, TEX. Location. The improvements authorized in the vicinity of Little Bay are located adjacent to the town of Fulton, Tex., which is on the west shore of Aransas Bay, on the south central coast of Texas, 30 miles northeast of Corpus Christi, Tex., and 3 miles northeast of Rockport, Tex. Existing project. This provides for an entrance channel 8 feet deep at mean low tide and 100 feet wide extending from that depth in Aransas Bay to a turning basin 8 feet deep at mean low tide, 200 feet wide and 1,400 feet long opposite the town of Ful- ton, Tex.; and for a protective dike on the north side of the basin, 1,000 feet long, connecting the north end of the existing break- water with the shore of Aransas Bay. Under ordinary conditions the mean tidal range in Aransas Bay is about 1 foot and the ex- treme range about 2 feet. The height of tide is dependent largely on the wind and, during strong "northers" in the winter season, the water surface may be depressed as much as 3 feet below mean low tide, while hurricanes have raised the surface as much as 12 feet above mean" low tide. The estimate of cost for new work is $33,300 (July 1951). The approved estimate of cost for annual maintenance is $3,000 (July 1951). The existing project was authorized by the River and Harbor Act of May 17, 1950, House Document 114, Eighty-first Congress, first session. Local cooperation. Local interests are required to furnish as- surances satisfactory to the Secretary of the Army that they will furnish without cost to the United States all lands, easements and rights-of-way necessary for construction and maintenance of the project, when and as required; construct a suitable bulkhead or breakwater around the north end of the proposed basin extend- ing from the north end of the existing concrete sheet-pile break- water to the shore; hold and save the United States free from damages due to the construction and maintenance of the project; RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 957 and adequately maintain the entire breakwater and dike after completion, except for the bulkhead or breakwater which has been constructed by local interests around the north end of the proposed basin. Terminal facilities. The existing terminal facilities consist of several privately-owned wharves'adjacent to sea food processing houses. All land fronting on the proposed harbor improvements has been acquired in fee simple title by the Aransas County Navi- gation District No. 1 and will be open to all on equal terms. Con- struction of the authorized improvements will permit accomoda- tion of existing commerce and provide for expansion of facilities to accommodate prospective commerce. Operations and results during fiscal year. None. Condition at end of fiscal year. Work remaining consists of the improvements as authorized by the River and Harbor Act of May 17, 1950, House Document 114, Eighty-first Congress, first session. The controlling depths at mean low tide were about 5 feet in the entrance channel and about 1 foot in the turning basin. A portion of the entrance channel and turning basin has previously been im- proved by local interests to the extent of dredging an entrance channel 6 feet deep and 80 feet wide from deep water in Aransas Bay to and including a turning basin of the same depth, 80 feet wide and 710 feet long, and by constructing a breakwater 965 feet long on the east side of the authorized turning basin. Proposed operations. No work is scheduled for fiscal years 1952 and 1953. 18. PORT ARANSAS-CORPUS CHRISTI WATERWAY, TEX. Location. This is a consolidation of the old improvements of Port Aransas, Tex., and the channel from Aransas Pass to Corpus Christi, Tex. Aransas Pass is on the southern portion of the coast of Texas, 180 miles southwest of Galveston and 132 miles north of the mouth of the Rio Grande. Aransas Pass connects Corpus Christi Bay and Aransas Bay with the Gulf of Mexico. The water- way extends from deep water in the Gulf through the Aransas Pass jettied entrance, thence westerly 203/4 miles to and including a turning basin at Corpus Christi, thence westerly 13/4 miles through the Industrial Canal to and including the turning basin at Avery Point, thence westerly 41/4 miles to and including a turn- ing basin near Tule Lake. (See U. S. Coast and Geodetic Survey Charts Nos. 523, 1285 and 1286.) Previous projects. The original project for improvement of Aransas Pass (Port Aransas) was authorized by the River and Harbor Act of March 3, 1879. The improvement was taken over by the Aransas Pass Harbor Co. on June 30, 1890, under authority of the act of May 12, 1890. This company relinquished its rights to the United States on March 27, 1899. The channel from Aransas Pass to Corpus Christi was first improved under the River and Harbor Acts of March 2, 1907, and June 25, 1910. For further details, see page 1861 of Annual Report for 1915 and page 877 of Annual Report for 1938. 958 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Existing project.

The project also provides for two rubblestone jetties at Aransas Pass entrance, extending into the Gulf from St. Joseph and Mus- tang Islands, the project lengths of which are 11,190 and 8,650 feet, respectively. The project further provides for a stone dike on St. Joseph Island about 19,100 feet long connecting with the north jetty and extending up this island to prevent a channel being cut around the jetty. Under ordinary conditions the mean tidal range at Aransas Pass is about 1.1 feet and the extreme range about 2 feet, and at Corpus Christi the mean range about 1 foot and the extreme about 11/ feet. The heights of tides are dependent largely on the strength and direction of winds, and during strong "northers" in the winter season the water surface may be depressed as much as 3 feet below mean low Gulf level. The estimated cost for new work exclusive of amounts ex- pended on previous projects, and exclusive of $217,000 contributed by local interests, is $15,172,000 (July 1951). The latest approved estimate for annual cost of maintenance is $749,000 (July 1951).

Recommended modification of project. Under date of June 8, 1950, the Chief of Engineers recommended modification of the existing project to provide for an anchorage basin 12 feet deep at mean low water, from 300 to 400 feet wide, and 900 feet long in Turtle Cove adjacent to the existing channel and turning basin at Port Aransas, Tex., with such modifications thereof as in the discretion of the Chief of Engineers may be advisable at an esti- mated cost to the United States of $30,000 for new work and $1,000 annually for maintenance in addition to that now required (H. Doec. 654, 81st Cong., 1st sess.). 960 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Local cooperation. Fully complied with except for the provi- sions of the River and Harbor Acts of June 20, 1938, March 2, 1945, and June 30, 1948, local interests being required to deepen and maintain at their own expense the channel through and for a distance of 50 feet on each side of the bridge at the entrance of the Corpus Christi turning basin, furnish free of cost to the United States all necessary lands, easements, rights-of-way, and spoil-disposal areas for the initial work and for subsequent maintenance as and when required, and furnish assurances satis- factory to the Secretary of the Army that they will hold and save the United States free from damages dues to construction and maintenance of the improvement; and provided further, that construction of the extension from Avery Point to Tule Lake shall not be undertaken until and unless local interests furnish assurances satisfactory to the Secretary of the Army that bona fide arrangements have been made with various industries to guarantee additional tonnage sufficient to warrant the construc- tion and maintenance of that canal to any point up to and includ- ing the proposed turning basin near Tule Lake, none of which has been complied with. Terminal facilities. Terminal facilities located on Harbor Island at the head of Aransas Pass, Ingleside, Corpus Christi, and Avery Point are considered adequate for existing commerce. (See Port Series, No. 25, revised in 1948, Corps of Engineers.)

Condition at end of fiscal year. The existing project was 41 percent complete. The two jetties have been partially completed, the north jetty being 9,240 feet long and the south jetty 7,385 feet long. A stone dike 20,991 feet long connecting with the north jetty was completed on St. Joseph Island in 1916. The inner basin at Harbor Island has been dredged to 30 feet below mean low tide over an area 650 feet wide and about 1,000 feet long. The channel from the inner basin to town of Port Aransas was completed in 1914. The 34-foot project, except for the Tule Lake extension, was completed in 1946. In 1949 the Tule Lake extension was dredged to partial dimensions with contributed funds. The work remaining consists of extending the north and south jetties 1,950 and 1,265 feet, respectively; extending inner basin at Harbor Island; deepening the outer bar to 38 feet, the jetty channel to 36 and 38 feet, all other deep water channels, includ- ing the previously dredged part of the inner basin at Harbor Island, to 36 feet, widening to 400 feet from Port Aransas to the maneuvering basin at Corpus Christi; and completing channel from Avery Point turning basin to and including a turning basin near Tule Lake. Extension of the inner basin at Harbor Island and extension of the jetties are not required at the present time. The controlling depths below mean low tide in the various chan- nels and basins were as follows: Aransas Pass outer bar channel, 39 feet; Aransas Pass jetty channel, 36.5 feet; inner basin at Har- bor Island 31 feet; channel from inner basin to west end of Hum- ble Oil & Refining Co. basin, 38 feet; channel to town of Port Aransas, 7.5 feet; turning basin at Port Aransas, 9.0 feet; chan- nel from west end of Humble Oil & Refining Co. basin to Corpus Christi turning basin, 32 feet; Corpus Christi turning basin, 34 feet; Industrial Canal, 36 feet; Avery Point turning basin, 36 feet; and channel from Avery Point turning basin to a point near the proposed Tule Lake turning basin, 14 feet.

BRAZOS ISLAND HARBOR, TEX. Location. At the extreme south end of the coast of Texas, about 7 miles north of the mouth of the Rio Grande, and about 125 miles south of Port Aransas. The harbor is at the inner end of Brazos Santiago Pass, which lies between Brazos and Padre Islands, and is the natural outlet from the Laguna Madre to the Gulf of Mexico. (See U. S. Coast and Geodetic Survey Chart No. 1288.) Previous projects. Authorized by River and Harbor Acts of June 18, 1878, March 3, 1881, and March 2, 1919. For further details, see page 1017, Annual Report for 1932, and page 882, Annual Report for 1938. Existing project. This provides for depths of 38 feet in the channel from deep water in the Gulf of Mexico through Brazos Santiago Pass and 36 feet in all other channels and basins; and widths of 300 feet in the channel from deep water in the Gulf of Mexico through Brazos Santiago Pass, 200 feet in the channel across Laguna Madre, 200 feet in the Port Isabel channel includ- ing the "wye" junction with the Brownsville channel, 200 feet in the Brownsville channel for a distance of about 12.6 miles and 300 feet for a distance of about 1.4 miles; from 550 feet to 1,000 feet in the Brownsville turning basin from this point for a dis- tance of 2,640 feet over a bottom width varying from 550 feet to 1,000 feet; for a small boat basin 12 feet deep, 300 feet wide and 1,500 feet in length with a connecting channel 12 feet deep and 125 feet wide adjacent to the existing Brownsville channel; and for 36 feet in the Port Isabel turning basin for a distance of 2,900 feet over a bottom width varying from 200 feet at its en- trance to 1,000 feet, connecting with the existing turning basin. All depths refer to mean low tide. The project also provides for two jetties at the Brazos Santiago Pass entrance. Under ordinary conditions the mean tidal range is about 11/2 feet and the extreme range about 2 feet. The height of the tides is dependent, to some extent, on the wind, and during strong "northers" in the winter season the water surface in the southern end of the Laguna 964 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Madre may be raised 4 feet or more above the mean low tide in the Gulf. The estimate of cost for new work is $8,039,000 (July 1951), which is exclusive of $1,683,257 contributed by local interests and of amounts expended on previous projects. The latest ap- proved estimate of annual cost of maintenance is $239,000 (July 1951).

Terminal facilities. On the westerly side of the turning basin at Port Isabel is located a wharf, 500 feet long containing a sheet-metal transit shed 100 by 350 feet and a precooling plant RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 965 with a capacity of approximately 24 cars every 8 hours. A sheet- metal warehouse 100 by 200 feet is located about 70 feet west of the transit shed. About 200 feet south of this wharf is a dock, 600 feet long by 16 feet wide, used for unloading tropical fruits and equipped with facilities for supplying diesel fuel to ships at the rate of 200 gallons per minute. Along the north end of the turning basin are two docks, one 300 feet long and the other 100 feet long, both equipped with facilities for receiving and loading oil cargoes, and for bunkering ships. All of the above facilities, owned by the Port Isabel-San Benito Navigation District, are serviced by railroad and highway connections and are open to all on equal terms. All docks and wharves are equipped with facilities for servicing ships with fresh water and electric current. An oil refinery and two storage tank farms, all privately owned, are located near the Port Isabel turning basin. This refinery has a maximum capacity of 10,000 barrels of refined products and a combined tank storage capacity of 552,000 barrels. Adjacent to the turning basin and having access to the Gulf Intracoastal Waterway is a shallow draft channel, one and one-half miles long, on which is located about three-fourths of a mile of privately- owned, low-level, wharves equipped with facilities for handling tropical fruits, barge traffic and sea foods. Additional facilities on this channel include 3 marine filling stations, several marine ways for handling small craft and medium size barges and an ice plant for servicing boats handling sea foods. These facilities are privately owned and operated, and are available on an indi- vidual contract basis. Along the north side of the Brownsville turning basin the Brownsville Navigation District has constructed three concrete wharves. Two of these wharves are 440 feet long and 165 feet wide with a timber dock extension 100 feet long and 36 feet wide. A metal warehouse 120 by 400 feet is located on each con- crete wharf. The third wharf is 400 feet long and 165 feet wide and contains a 120- by 390-foot metal warehouse. Also on the north side of the turning basin is located a concrete dock 1,000 feet long and 140 feet wide with a 500- by 100-foot metal ware- house located on the dock. Along the west end of the basin is a concrete wharf 450 feet long and 165 feet wide containing a 400- by 120-foot metal warehouse. All of the above terminals have rail facilities. On the west end of the basin is a timber dock 400 feet long used for servicing small craft. Located on the south- west corner of the turning basin is a marine ways for servicing shrimp boats and other small craft and a repair shop operated in connection therewith, all of which are privately owned. On the south side of the turning basin, towards the west end, is located a concrete barge dock 300 feet long and 100 feet wide with a 400-foot unloading and storage apron, complete with rail- road spur track. Also located on the south side of the basin is a concrete dock 525 feet long and 20 feet wide, with two open steel sheds 32 by 280 feet located thereon. This dock is equipped with complete systems for handling tropical fruits and is served by two railroad spur tracks. On the west side of the south slip is located 966 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 a concrete open dock 500 feet long and 100 feet wide, equipped with a railroad spur track to the rear of the apron. On the east side of the turning basin is a timber wharf 10 feet wide and 800 feet long for docking and servicing shrimp trawlers. Back of this wharf are two 40- by 80-foot, privately owned shrimp processing plants. There are also four marginal timber docks, each 11 feet wide and 100 feet long, extending into the basin from shore at 52-foot intervals and equipped with facilities for servic- ing shrimp trawlers with ice and fuel. This entire area is served by an open, hard-surfaced road and parking area. On the north side of the channel and to the east of the turning basin are located three 500-foot oil docks with direct pipeline connections to the bulk-oil terminals and to the chemical refining and separating plants, also a 350-foot concrete oil-barge dock with direct pipeline connections to the chemical refining and separating plants. North of the general cargo terminal is a privately owned, high-density cotton compress, with a storage capacity of 46,000 bales, covering an area of 347,000 square feet. Also north of the general cargo terminal is a bonded warehouse having a storage capacity of 10 acres and equipped with rail facilities. On the southwest corner of the Navigation District property is located a privately owned cotton compress and warehouse having 320,000 square feet of storage space and a storage capacity of 60,000 bales. In addition, two cotton compresses are located in the city of Brownsville, Tex. These compresses have combined storage capacity of 90,000 bales and are serviced by direct rail and truck connections with port facilities. The Brownsville Navigation District employs one steam locomotive crane of 30-ton capacity and one rubber-tired mobile crane of 15-ton capacity on the terminal. All concrete docks and wharves have complete bunker facilities. All docks and wharves are equipped with facilities for handling and/or storing crude and refined oil. These docks all have direct pipeline connections to the various oil storage terminals. There are five privately owned terminals equipped with facilities for .handling petroleum products having a combined maximum storage capacity of 1,036,- 475 barrels. Two chemical refining and separating plants are located on Navigation District property to the east of the port proper, and have adequate facilities servicing the oil loading docks, including railroad and highway connections which are open to all on equal terms. Operations and results during fiscal year. Maintenance: Peri- odic surveys and inspections were made at a cost of $6,290.53. A total of 52,470 cubic yards of material was removed from the Port Isabel Turning Basin by contract during the period June 26-30, 1951, at a cost of $14,356.44. The total cost for the fiscal year was $20,646.97. The total expenditures were $14,448.48. Condition at end of fiscal year. The existing project is 66 per- cent complete. The 25-foot project channels and jetties were com- pleted in 1936. The deepening of the sea bar and jetty channels to the 31-foot depth and of the inside channels and basins to the 28-foot depth was completed in 1940. Widening and deepening the RIVERS AND HARBORS-GALVESTON, TEX., DISTRICT 967 Port Isabel turning basin as authorized by the River and Harbor Act of March 2, 1945, was completed in 1947. The 32-foot project channels and basins were completed in 1949. Work remaining consists of deepening the entrance channel to 38 feet at mean low tide from deep water in the Gulf of Mexico through Brazos Santi- ago Pass, deepening to 36 feet all other channels and turning basins, widening to variable widths certain sections of the chan- nels, extending the Brownsville and Port Isabel turning basins and constructing a small boat turning basin with a connecting channel adjacent to the Brownsville Ship Channel.

These improvements are located on Buffalo Bayou, a tributary of the San Jacinto River, in Harris County, west and northwest of the city of Houston, Tex. (See U. S. G. S. quadrangle sheets for Harris County.) Existing project. This provides for the improvement of Buf- falo Bayou and its tributaries above the turning basin (Houston) of the Houston Ship Channel to provide for the control of floods, the protection of the city of Houston from flood damages, and the prevention of the deposit of silt in the turning basin of the Hous- ton Ship Channel by means of detention reservoirs, enlargement and rectifications of channels, the construction of control works, and any diversions which may be found advisable. The authorized cost of Federal participation for construction is limited to $9,000,- 000. The current estimated Federal cost, approved in 1951, is $9,- 000,000 for construction and $13,305,400 for lands and reloca- tions; the current estimated cost to local interests approved in 1951, is $22, 130,700, a total of $44,436,100. The estimated annual cost for maintenance is $114,600 (July 1951). The existing project was authorized by the River and Harbor Act approved June 20, 1938 (H. Doc. 456, 75th Cong., 2d sess.), and the Flood Control Act approved August 11, 1939. Local cooperation. See pages 4-5 for requirements. The re- quirements are being complied with. The offer of the Harris County flood-control district to advance the sum of $2,900,000 to the Department for prosecution of the Buffalo Bayou project was accepted by the Secretary of War on December 18, 1940, and July 10, 1945. Operations and results during fiscal year. New work: Opera- tions during the fiscal year consisted of continuation of land FLOOD CONTROL--GALVESTON, TEX., DISTRICT 975 acquisition for Barker Reservoir, Addicks Reservoir, and Buffalo Bayou rectified channel at a cost of $203,333.56. Maintenance: Routine operations, maintenance, and care were carried on from July 1, 1950, to June 30, 1951, on Barker and Addicks Dams and the rectified channels at a cost of $78,668.78. Preliminary work and surveys for application of a seal coat by contract to a part of the stabilized crown of Barker Dam were done at a cost of $678.25. The total cost of all work for the fiscal year was $282,680.59, of which $203,333.56 was for new work and $79,347.03 was for maintenance. The total expenditures were $272,141.41.

The Neches River has its source 60 miles southeast of Dallas and flows generally southeast 416 miles to Sabine Lake 4 miles east of Port Arthur, Tex. The Angelina River flows south- east 200 miles to its confluence with the Neches River 126 miles above its mouth. The authorized features are located as follows: Rockland Dam on Neches River approximately 3 miles west of Rockland, Tex.; McGee Bend Dam on Angelina River approxi- mately 10 miles northwest of Jasper, Texas; Dam A on Neches River approximately 4 miles west of Horger, Tex.; Dam B on Neches River approximately one-half mile north of Town Bluff, Tex. (See U. S. Geological Survey Base Map, Northeast Texas, Scale 1:500,000). Existing project. The plan of improvement provides for dams and 'reservoirs to be located at the Rockland and McGee Bend dam sites on the Neches and Angelina Rivers, respectively, which will effect a large measure of flood protection to agricultural lands in the lower river valley and to the city of Beaumont, reduce the hazards to navigation resulting from floods, and provide a regu- lated flow in the lower river to supply municipal, agricultural, and industrial demands. In addition these proposed projects would permit the development of a large amount of firm power and afford opportunities for recreation. The plan also provides for construction of Dam A, located on the Neches River below Rockland Dam, for the development of power; and Dam B, located below the confluence of the Angelina and Neches Rivers, to regulate the daily fluctuations in discharge from the turbines in the upper projects and to develop a limited amount of power. Construction of Rockland and Dam A Reservoirs and of power facilities at Dam B is to be deferred until justified by future con- ditions.

RIVERS AND HARBORS-FORT WORTH, TEX., DISTRICT 983 The estimated cost of the project (July 1951) is $85,996,500 for construction and $12,840,700 for lands and damages, a total of $98,837,200, including $5,000,000 to be contributed by local interests. The existing project was authorized by the River and Harbor Act, approved March 2, 1945, for regulating the flow of Neches River and tributaries for the benefit of navigation, the control of floods, the conservation of water, and the development of hydro- electric power (See S. Doc. 98, 76th Cong., 1st sess.) The River and Harbor Act approved June 30, 1948 modified this project so as to provide that the local agency which gives assurances that upon completion of the entire project it will con- tribute toward the first cost of the work the sum of $5,000,000, will be permitted to withdraw from the pool of Dam "B" not to exceed 2,000 cubic feet of water per second for its own use (Pub- lic Law No. 858, 80th Cong., 2d sess.). Local cooperation. This project was adopted subject to the provision that before construction is started upon any element of the project, the State of Texas or other responsible local agency give assurances satisfactory to the Secretary of the Army that upon completion of the entire project it will contribute to- ward the first cost of the work the sum of $5,000,000. The Lower Neches Valley Authority has furnished assurances, approved by the Secretary of the Army on November 13, 1947, that at any time after Congress appropriates sufficient funds for construc- tion Dam B and its reservoir which, as estimated by the Corps of Engineers, United States Army, would by the addition of $2,- 000,000 be sufficient to complete Dam B and its reservoir, upon demand by the Secretary of the Army, the Authority will con- tribute $2,000,000 toward the construction of Dam B and its reservoir; and upon completion of the McGee Bend Dam and its reservoir the sum of $3,000,000 will be contributed toward the first cost of the project. To date $2,000,000 has been contributed toward the first cost of Dam B. Operations and results during fiscal year. Operations during the fiscal year consisted of continuation of land acquisition for Dam B; completion of contract for construction of earthen em- bankment and spillway, Dam B; and completion of reservoir clear- ing operations, Dam B. Review of the preliminary investigations and engineering studies for McGee Bend, with a view to reducing the size of this element of the project, was continued.

GRAPEVINE RESERVOIR, TEX. Location. The improvement is located in Tarrant and Denton Counties, Tex., on Denton Creek, 11.7 river miles upstream from its confluence with the Elm Fork of the Trinity River and about 20 miles northwest of the city of Dallas, Tex. Existing project. The plan of improvement, a unit of the com- prehensive plan for flood control in the Trinity River Basin, pro- vides for the construction of an earth dam approximately 12,675 feet in length, including an uncontrolled concrete spillway 500 feet in length, located in the left abutment. The dam has a maximum height of 137 feet above the stream bed. The reservoir will pro- vide a storage capacity of 238,200 acre-feet for flood control, 160,000 acre-feet for conservation purposes, and a sedimentation reservoir of 36,000 acre-feet. The reservoir extends 22.2 miles upstream. The estimated cost of the project, (July 1951) is $8,- 862,861 for construction and $2,801,139 for lands and damages, a total of $11,664,000, including $2,174,000 to be contributed by local interests.

SMALL FLOOD CONTROL PROJECTS UNDER AUTHORITY OF SECTION 205 OF THE FLOOD CONTROL ACT APPROVED JUNE 30, 1948, AS AMENDED Section 205 of the Flood Control Act approved June 30, 1948, as amended by section 212 of the Flood Control Act approved May 17, 1950, authorized the allotment from any appropriations heretofore or hereafter made for flood control, not to exceed $3,000,000 for any one fiscal year, for construction of small flood control projects not specifically authorized by Congress, and not within areas intended to be protected by projects so authorized which come within the provisions of section 1 of the Flood Con- trol Act of June 22, 1936, when in the opinion of the Chief of Engineers such work is advisable: Provided, That not more than $150,000 shall be allotted for this purpose at any single locality from the appropriations for any one fiscal year: Provided further, That the provisions of local cooperation specified in section 3 of the Flood Control Act of June 22, 1936, as amended, shall apply: And provided further, That the work shall be complete in itself and not commit the United States to any additional im- provement to insure its successful operation, except as may result from the normal procedure applying to projects authorized after submission of preliminary examination and survey reports. Pursuant to these authorities expenditures were made in the amount of $7,314.18 during fiscal year 1951 for a project report on emergency flood control measures for protection of the city of Socorro, N. Mex., and for emergency flood control measures for protection along Pinon Canon at Trinidad, Colo. Instrumental FLOOD CONTROL-ALBUQUERQUE, N. MEX., DISTRICT 1039 surveys, hydrologic studies, economic studies and investigations, engineering design, and cost estimates of the Socorro, N. Mex., project were completed; however, the report was not submitted for the reason that investigations revealed that a project pro- viding a higher degree of protection would be justified. It was recommended that the review report on the Rio Grande in the vicinity of Socorro, authorized by resolution of the Senate Com- mittee on Public Works adopted September 8, 1950, be submitted in lieu of the project report. Instrumental surveys and hydro- logic studies of the Pinon Canon project at Trinidad, Colo., were initiated and report will be completed in fiscal year 1952. Total costs for all work under this heading to the end of the fiscal year were $7,492.47. The expenditures were $7,314.18. The unexpended balance, $7,985.82, will be applied to accounts payable on June 30, 1951, in the amount of $178.29 and as required to complete the work authorized.

ARKANSAS RIVER AND TRIBUTARIES, ARK. AND OKLA., NAVIGATION FEATURES Location. The Arkansas River rises in the Rocky Mountains near Leadville, Colo., and flows southeastward for about 1,450 miles through the States of Colorado, Kansas, Oklahoma, and Arkansas to join the Mississippi River at a point about 575 miles above the Head of Passes, La. (See U. S. Geological Survey State maps, scale 1: 500,000). Previous projects. Previous projects were adopted by the River and Harbor Acts of July 3, 1832, April 8, 1876, March 3, 1879, June 14, 1880, July 5, 1884, August 5, 1886, August 11, 1888, June 13, 1902, and March 2, 1907. For further details see page 1066, Annual Report for 1932, and pages 744, 864, and 881, Annual Report for 1943. Existing project. The River and Harbor Act of July 24, 1946, approved the multiple-purpose plan recommended in the report of the Chief of Engineers dated September 20, 1945 (H. Doc. 758, 79th Cong., 2d sess.), and letter of the Chief of Engineers dated March 19, 1946, and limited appropriations thereunder to $55,- 000,000 for initiation and partial accomplishment of the project. The River and Harbor and Flood Control Acts of May 17, 1950, increased the authorization for appropriations to $135,000,000 and modified the multiple-purpose plan and the general compre- hensive plan for flood control by substitution of Keystone Reser- voir, located on the Arkansas River 538.9 miles above the mouth, for the approved Mannford Reservoir on the Cimarron River and by deletion of the approved Blackburn and Taft Reservoirs on the Arkansas River as recommended by the Chief of Engineers (Senate Doc. 107, 81st Cong., 1st sess.). Details concerning the Keystone Reservoir are shown under flood control, Tulsa district. The existing project provides for improvement of the Arkansas River and tributaries by construction of coordinated develop- ments to serve navigation, produce hydroelectric power, afford additional flood control, and provide related benefits in connec- tion with other activities such as recreation and wildlife propa- gation. The navigation features provide for a channel 9 feet deep following generally the Verdigris River from Catoosa, Okla., 52 miles downstream to the Arkansas River; thence along the chan- nel of the latter stream to mile 51 (1940 survey); thence by a land cut, designated as the Arkansas Post route, to the White River at mile 18.3; thence along the channel of the White River to mile 7.8; thence by a land cut to the Mississippi River at a point about 590.5 miles above the Head of Passes, La. The water- way would be canalized throughout its length by three navigation locks and dams on the Verdigris River and 16 navigation locks and dams and 4 navigation and hydroelectric power dams down- stream therefrom. The 4 navigation and power dams are the Webbers Falls, Short Mountain, Ozark, and Dardanelle projects. Lock chambers are 110 by 600 feet on the Arkansas and White Rivers and 83 by 600 feet on the Verdigris River. A minimum channel width of 150 feet is proposed for the Verdigris River section and 250 feet for the Arkansas and White River sections.

The active features of the project are reported individually on following pages. The existing project was authorized by the River and Harbor Act of July 24, 1946, as amended by the Flood Control Act of May 17, 1950. (See H. Doec. 758, 79th Cong., 2d sess., which contains the latest published maps.) Local cooperation. Local interests are required to provide adequate terminal and transfer facilities for navigation and bear the increased cost of maintenance and operation of all altered rail and highway routes, including bridges and appurtenances, utilities, and other existing improvements, other than Federally owned. Terminal facilities. Terminal facilities along the Arkansas River consist of a paved bank slope, under municipal control, at Little Rock; privately owned log slips at sawmills and stave mills at Little Rock; and sand and gravel derricks and elevators at Van Buren, Dardanelle, Little Rock, and Pine Bluff. These facilities, which are adequate for existing commerce on the river, are located at or near rail connections. RIVERS AND HARBORS--LITTLE ROCK, ARK., DISTRICT 1047 Operations and results during fiscal year. Under the direction of the Arkansas River Board, consisting of the district engineers of the Vicksburg, Little Rock, Albuquerque, and Tulsa districts, engineering studies made to date were summarized and a revised project estimate was prepared in the light of changes of plan and more adequate engineering data. Among the general items studied were navigation routes, type of navigation dams for the Arkan- sas River, design criteria, and sedimentation and degradation. Bank-stabilization studies were continued. One contract for bank stabilization in the reach from Dardanelle Rock to Reeds Ferry was completed. Bank stabilization in the reach from White Bluff to the Jefferson County free bridge and excavation of a pilot channel in the same reach were continued by contract.

The existing project was authorized by the River and Harbor Act approved July 24, 1946. (House Doc. 758, 79th Cong., 2d sess.) Local cooperation. See requirements for entire project. Operationsand results during fiscal year. Engineering studies and investigations including geological explorations, hydraulic studies, and related work leading to the development of a definite plan for navigation from Little Rock to the mouth, and the prep4- ration of a definite project report for a typical lock and dam (No. 7) was continued during the fiscal year. Extensive studies in connection with Lock and Dam No. 7 were made to select the type of navigation dam best suited for use on the Arkansas River. As a result of these studies the non-navigable-type dam was selected for estimating and planning purposes. For the purpose of preparing the revised project estimate the survey report loca- tions of locks and dams were reviewed in the light of latest approved criteria adopted by the Arkansas River Board, antici- pated degradation, recent data on regimen of the river, and present developments along the stream, particularly levee systems and the effect of the plan on interior drainage. As a result of these studies the major change from the survey report lay-out has been the elimination of three locks and dams in the lay-out established for the revised estimate. The costs during the fiscal year for new work were $13,108.16 for planning a typical navigation lock and dam (No. 7), and $57,772.26 for planning other navigation features. The unsegre- gated expenditures during the fiscal year for Dardanelle Dam and Reservoir, navigation locks and dams, and bank stabilization were $1,022,783.88 for new work. Condition at end of fiscal year. Subsequent to the preparation of the revised lay-out of locks and dams and completion of the cost estimate, studies leading to the development of a definite plan for navigation and the preparation of a definite project report for Lock and Dam No. 7 were discontinued due to the lack of adequate planning funds, and studies were placed in a stand-by condition as to the end of the fiscal year. Planning work for the Lock and Dam No. 7 definite project report was estimated to be 40 percent complete. The total cost to the end of the fiscal year for a typical navi- gation lock and dam was $76,786.18, and planning for other navigation features was $79,376.23 for new work. Unsegregated expenditures to the end of the fiscal year, including Dardanelle Dam and Reservoir and bank stabilization, were $1,516,068.67 for new work. Proposed operations.

All work was for maintenance with Government plant and hired labor at locks and dams 1, 2, and 3. Work during the fiscal year consisted of operation of the locks and routine maintenance of appurtenant river structures, buildings, and grounds. The United States der- rick boat No. 2001 during July 1950 removed 1,200 cubic yards of mud and sunken drift from the fleet harbor near lock 1 and from the lock upper gate recess. The costs during the fiscal year were $277.16 for maintenance and $31,227.10 for operation and care. The total expenditures were $30,205.17. Condition at end of fiseal year. The new work accomplished to the end of the fiscal year is the construction of three locks and dams mentioned under paragraph "Existing project." The proj- ect, as amended, is complete. The works, by aid of dredging, give all-year slack-water navigation for 4-foot draft from 1 mile below Batesville to Guion, which is 29 miles upstream therefrom.

FORT SMITH, ARKANSAS RIVER, ARK. Location. This project is located on the right bank of the Arkansas River at and in the immediate vicinity of Fort Smith, Sebastian County, Ark., just downstream from the mouth of the Poteau River (mile 362.0). (See U. S. Geological Survey map for Fort Smith (Ark.) quadrangle.) FLOOD CONTROL-LITTLE ROCK, ARK., DISTRICT 1065 Existing project. The plan of improvement provides for the construction of a compacted earth-fill levee, concrete flood wall, and two pumping stations on the right bank of the Arkansas River in the reach from the Missouri Pacific Railroad embank- ment at mile 361.8 to a point opposite mile 360. The length of the levee and flood wall is about 1.2 miles and 0.6 mile, respectively, or a total length of about 1.8 miles. Four new drainage structures, equipped with floodgates, have been built. One of the existing sewer lines intercepts the storm run-off from approximately 3,642 acres, and the sewage from about 50 percent of the resi- dential district of the city. In order to reduce the pump capacity which would be required 'for pumping the flow in this line, a storage area comprising an existing creek channel and borrow areas within the leveed area has been utilized for temporary ponding of run-off. The sewer line is connected to the storage area by means of a relief outlet. The project provides for the protection of the city of Fort Smith, Ark., with a levee and flood- wall having a 3-foot freeboard above a confined flood profile based on a flow of 800,000 cubic feet per second in the river. The Federal cost of the completed project, is $1,077,546 for construction and the estimated cost to local interests of land and damages is $138,279, a total of $1,215,825. The existing project was authorized by the Flood Control Act approved December 22, 1944, as amended by Sec. 3 of the Flood Control Act approved June 24, 1946. (See H. Doc. 447, 78th Cong., 2d sess.) Local cooperation. See pages 4-5 for requirements. The neces- sary assurance of local cooperation submitted by local interests were approved by the Secretary of War on June 24, 1946. All rights-of-way required for construction have been furnished. Operations and results during fiscal year. Raising the Missouri Pacific Railroad bridge was completed December 30, 1950.

This project is located on the left bank of the Arkansas River at and in the immediate vicinity of the city of Van Buren (mile 353.4), Crawford County, Ark. (See U. S. Geological Survey map for Fort Smith (Ark.) quadrangle.) Existing project. The plan of improvement provides for the construction of a compacted earth-fill levee, a concrete flood wall, an intercepting storm sewer and ditch, and a sanitary sewage pumping station on the left bank of the Arkansas River in the reach from high ground near the St. Louis-San Francisco Rail- way bridge (mile 353.7) to the city limits at a point on the exist- ing Crawford County levee opposite mile 352.7. The levee connects with the authorized project for Crawford County levee district. The total length of the levee and flood wall is about 1.3 miles, of which approximately 0.4 mile is new levee, 0.6 mile is riverside enlargement of the existing Crawford County levee, and about 0.3 mile is reinforced concrete flood wall. Four existing storm drains which discharge into the Arkansas River are provided with drainage structures in the levee and flood wall and are equipped with flood-gates. An intercepting sewer and ditch con- veys interior run-off occurring during high river stages to Ned Lake in the Crawford County levee district. The project provides for the protection of the city of Van Buren, Ark., with a levee and floodwall having a 3-foot freeboard above a confined flood profile based on a flow of 800,000 cubic feet per second in the river. The Federal cost of the completed project is $438,086.78 for construction and the estimated cost to local interests for lands and damages is $50,000, a total of $489,000. The existing project was authorized by the Flood Control Act approved December 22, 1944, as amended by Sec. 3 of the Flood Control Act approved July 24, 1946, and the Flood Control Act approved June 30, 1948.

CRAWFORD COUNTY LEVEE DISTRICT, ARKANSAS RIVER, ARK. Location. This project is located on the left bank of the Arkansas River from near the eastern limits of the city of Van Buren, Ark. (mile 352.7) to near the mouth of Frog Bayou (mile 331.9), Crawford County, Ark. (See U. S. Geological Survey map for Fort Smith (Ark.) quadrangle.) Existing project. The plan of improvement provides for the construction of a compacted earth-fill levee, approximately 19.8 miles long, extending from the downstream end of the Van Buren, Ark., project at mile 352.7 downstream to mile 332, near the mouth of Frog Bayou. This levee follows the present alinement of an existing levee except at the locations where encroachment of the river made it advisable to set the levee farther from the banks. Six new drainage structures, equipped with floodgates, have been built. The existing project for the Crawford County levee district, which is a modification of the previously authorized flood-control project, provides for the protection of approximately 15,060 acres of rural lands and communities with a levee having a 11/2-foot freeboard above a confined flood profile based on a flow of 800,000 cubic feet per second in the river. The modified project differs from the previously authorized project in that it provides for a levee grade about 7 feet higher and a compacted earth-fill em- bankment. The Federal cost of the project, revised in 1951, is $2,142,000 for construction and the estimated cost of local interests for lands and damages is $74,000, a total of $2,216,000. The existing project, authorized by the Flood Control Act ap- proved December 22, 1944, and modified by Sec. 3 of the Flood Control Act approved July 24, 1946, and the Flood Control Act approved June 30, 1948, is a modification of the project authorized by the Flood Control Act approved August 18, 1941. (See H. Doc. 447, 78th Cong., 2d sess.) Local cooperation. See pages 4-5 for requirements.

BLUE MOUNTAIN RESERVOIR, ARKANSAS RIVER BASIN, ARK. Location. The Blue Mountain Dam is located in Yell County, Ark., on the Petit Jean River about 74.4 miles above its conflu- ence with the Arkansas River, and about 12 miles south of Paris, Logan County, Ark. Blue Mountain Reservoir extends west- ward from the dam into Logan County. (See U. S. Geological Survey map for Magazine, Ark., quadrangle, scale 1:125,000.) Existing project. The plan of improvement provides for the construction of an earth-fill dam about 2,800 feet long and about 115 feet in height above the stream bed. Outlet works consist of a gate-controlled, concrete-lined tunnel through the right abut- ment, discharges from which are directed back into the Petit Jean River at a point about 3,000 feet below the dam. An un- controlled saddle spillway is located on the left abutment, about 1,200 feet downstream from the dam axis. The reservoir, which is one unit of a comiprehensive plan for flood control and other purposes in the Arkansas River Basin, controls approximately 46 percent of the total drainage area of the Petit Jean River. It provides storage capacity of about 233,000 acre-feet for flood control, and a permanent pool of about 25,000 acre-feet for recreational purposes and as a wildlife refuge. The estimated cost of the project, revised in 1951, is $4,365,- 907 for construction and $545,733 for lands and damages, total- ing $4,911,640. The estimated cost of annual maintenance, made in 1950, is $75,000. The existing project was authorized by the Flood Control Act approved June 28, 1938. Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies. Operations and results during fiscal year. Ordinary mainte- nance and operation of the project were continued. Construction of the administration building by contract was completed on April 6, 1951. Grading and landscaping around the administra- tion building and overlook shelter by hired labor are under way. Review of the master plan for reservoir development to deter- mine the scope and estimated cost of work required to complete the program is under way. FLOOD CONTROL--LITTLE ROCK, ARK., DISTRICT 1079 Six notable rises occurred on the Petit Jean River during the fiscal year. Flooding was prevented on an average of about 7,380 acres of improved land for each flood. The results of flow regulation on river stages at Danville are given in the following tabulation.

NIMROD RESERVOIR, ARKANSAS RIVER BASIN, ARK. Location. The Nimrod Dam is located in Perry County, Ark., on the Fourche La Fave River, 62.6 miles above its confluence with Arkansas River, and about 19 miles southeast of Danville, Yell County, Ark. (See U. S. Geological Survey map for Hot Springs, Ark., quadrangle, scale 1:125,000.) Nimrod Reservoir extends westward from the dam into Yell County. Existing project. The plan of improvement provides for the construction of a concrete gravity type dam 995 feet long and about 97 feet in height above the stream bed. It consists of a spillway section 198 feet long located above the river channel, and two non-overflow sections contiguous thereto and extending FLOOD CONTROL-LITTLE ROCK, ARK,, DISTRICT 1081 into the abutments. Seven gate-controlled conduits for regulat- ing and discharging flood flows are located through the base of the spillway section. In addition, two smaller valve-controlled conduits are provided through the spillway section for regulat- ing low flows. Penstocks and provisions for future spillway gates have been installed to provide for future power generation. The reservoir, which is one unit of a comprehensive plan for flood control and other purposes in the Arkansas River Basin, controls approximately 60 percent of the entire drainage area of the Fourche La Fave River. It provides storage capacity of about 307,000 acre-feet for flood control, and a permanent pool of about 29,000 acre-feet for recreational purposes and as a wildlife refuge. The estimated cost of the project, revised in 1951, is $3,087,- 090 for construction and $778,310 for lands and damages, total- ing $3,865,400. The estimated cost of annual maintenance, in July 1950, is $75,000. The existing project was authorized by the Flood Control Act approved June 28, 1938. Local cooperation.

EAST POPLAR BLUFF AND POPLAR BLUFF, MO. Location. This project is located on the left bank of the Black River in and adjacent to the eastern part of the city of Poplar Bluff, Butler County, Mo. (mile 210.9). (See U. S. Geological Survey may for Poplar Bluff, Mo., quadrangle, and Corps of Engineers map for Harviell, Mo., quadrangle.) Existing project. The plan of improvement provides for a new compacted earth-fill levee encircling that part of the city of Poplar Bluff lying east of the Black River. The levee will begin at a point opposite Black River mile 211.8, extend southeastward along Palmer Slough and across the Missouri Pacific Railroad, then southward to Black River at mile 208.4, thence up the left bank of Black River and along the city water front to the point of begin- ning. The plan will require construction of 3.2 miles of standard levee; raising of 1.4 miles of streets to serve as levee; construction of one large drainage structure and eight small culverts; installa- tion of a sewage pumping station; and excavation of 0.7 mile of ditch along the riverside of the east levee. The levee will have a 3-foot freeboard above the flow line of a project flood as modified by Clearwater Reservoir and confined by the levee. The discharge of the modified project flood is 37,000 cubic feet per second. Pro- tection will be provided for 410 acres within the city of Poplar Bluff and for 310 acres adjacent thereto. This plan of improve- ment is a modification of the original project plan and provides essentially the same degree of protection. The estimated Federal cost of the project, revised in 1951, is $290,000 for construction and the estimated cost to local interests for lands and damages is $26,000, a total of $316,000. The existing project was authorized by the Flood Control Act approved June 22, 1936. (See H. Doc. 102, 73d Cong., 1st sess.) FLOOD CONTROL-LITTLE ROCK, ARK., DISTRICT 1085 Local cooperation.

BLACK RIVER, POPLAR BLUFF, MO., TO KNOBEL, ARK. Location. This project is located on the right and left banks of Black River in Butler County, Mo., and Clay County, Ark., between Poplar Bluff, Mo., (mile 210.9), and latitude of Knobel, Ark. (mile 140). (See U. S. Geological Survey map for Poplar Bluff, Mo., quadrangle, and Corps of Engineers maps for Harviell, Mo., Rector, Ark.-Mo. and Knobel, Ark.-Mo. quadrangles.) Existing project. The plan of improvement provides for flood protection along Black River, Ark. and Mo., from a point near the Missouri Pacific Railroad in Poplar Bluff, mile 210.9, down- stream to the latitude of Knobel, Ark., mile 140. The plan of improvement for the Arkansas portion of the proj- ect between miles 140 and 173 provided for construction of levees and drainage structures. This work was completed at a cost of $445,600 and transferred to local levee districts for maintenance and operation in June 1941. The plan of improvement for the Missouri portion of the proj- ect provides for construction of a new levee along the right bank of Black River from Poplar Bluff to a point near the Missouri- Arkansas State line; enlargement of the Inter-River drainage 1086 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 district levee and the upper part of the Arkansas portion of the Poplar Bluff, Mo., to Knobel, Ark., levee, and the construction of a pumping station, for protection against Black River floods. The levee along the west or right bank of Black River will be a cohpacted-earth fill. It will extend from a point near the Missouri Pacific Railroad bridge in Poplar Bluff downstream to a cut-off to be made across the neck of the river loop between miles 210.6 and 209.9, thence along the right bank of the cut-off and along the natural river bank and the existing levee to river mile 208.4. It will extend from there downstream parallel to Black River to a point opposite Whitlow, Mo. From there it will parallel the existing levee, generally on the riverside, to the State line and thence extend southwestward to an open end at river mile 165.7. The grade of the upper 2.3 miles of levee will be 3 feet above the profile of the modified and confined design flood (37,000 cubic feet per second), and the grade of the remainder will be not less than 2 feet above the profile of that flood. The new levee will be 28 miles long and have an average height of 10.5 feet. The proposed enlargements along the left bank will make those structures equivalent in grade and cross section to the right bank levee. The total length of enlarged levees will be 35.4 miles, and the average height will be 8.5 feet. This plan is a modification of the original project plan and provides essentially the same degree of protection. The Federal cost of the Missouri portion of the project, revised in 1951, is $3,734,000 for construction and the estimated cost to local interests for lands and damages is $166,000, a total of $3,900,000. The existing project was authorized by the Flood Control Act approved June 22, 1936. (See H. Doc. 102, 73d Cong., 1st sess.) Local cooperation. See pages 4-5 for requirements. The neces- sary assurances of local cooperation, covering that part of the plan of improvement lying west of Black River in Missouri, submitted by local interests were approved July 11, 1947. Operations and results during fiscal year. Hydrologic studies and preparation of detailed plans were continued. Contract for design of pumping station was awarded April 30, 1951. The costs during the fiscal year were $2,281.80, all for new work. The expenditures were $1,835.40. Condition at end of fiscal year. Preparation of detailed plans for the levee is 65 percent complete. The definite project report on the pumping station has been completed and approved. The total costs to the end of the fiscal year were $481,035.42 and the expenditures were $481,044.80, all for new work (includ- ing the cost and expenditures of $445,584.54 for previous con- struction of the Arkansas portion only during the fiscal years 1938 to 1942, inclusive). Proposed operations. The balance unexpended June 30, 1951, including accounts receivable, $109,049.12, will be applied during fiscal year 1952 to continuation of planning by hired labor and to construction of the pumping station by contract. No work is scheduled for fiscal year 1953.

Stream gaging, field surveys, foundation explorations, compilation of land ownership data, plans and specifications, and studies in connection with the development of the general comprehensive plan were continued by hired labor during the year. One noteworthy rise occurred on the Upper White and North Fork Rivers during the fiscal year. Regulation of the rise on the North Fork River by the Norfork Reservoir and modification of the flow from the Upper White River in Bull Shoals Reservoir, which is under construction, resulted in protection of about 39,000 acres of improved land along the White River. Flood modification on the White River at Calico Rock, 17 miles downstream from the mouth of the North Fork River and 59 miles downstream from Bull Shoals Dam, and at Newport, 102 miles downstream from Calico Rock, is given in the following tabulation.

HUTCHINSON, ARKANSAS RIVER, KANS. Location. The work covered by this project is located on the Arkansas River and Cow Creek, a tributary of the Arkansas River, in the immediate vicinity of Hutchinson, Kans. (See U. S. FLOOD CONTROL-TULSA, OKLAHOMA, DISTRICT 1113 Geological Survey maps for Lyons and Hutchinson (Kans.) quad- rangles, scale 1:125,000.) Existing project. The plan of improvement consists of a 300-foot-wide leveed diversion canal approximately 1 mile west of the city limits of Hutchinson, intercepting Cow Creek at mile 14.9 above its mouth and carrying floodwaters from the creek south for about 2 miles to enter the Arkansas River at mile 822.3 above its mouth. The levee on the left bank of the diversion canal starts at the hills about 41/2 miles north of the canal to intercept all of Cow Creek floodwaters. The combined flow of the creek and the river is confined past the city by levees on both sides of the river, forming a 1,000-foot - floodway. The flanking levee on the right bank of the Arkansas River starts at mile 822.3 above the mouth of the river and extends downstream to mile 818.5. The flanking levee on the left bank of the Arkansas River starts at the diversion canal and extends downstream to mile 816.5, with an opening at the mouth of the present Harsha drainage canal. Protection against backwater of the Arkansas River up the existing canal is provided by increasing the height of the existing levees. Additional protection is provided to a rural area west of the diversion canal by a loop levee, and to the urban area of the Island Park Subdivision, northwest of Hutchin- son, by a ring levee. The project provides for the protection of of 17,460 acres of industrial, urban, and agricultural land, with grade elevation allowing a 3-foot freeboard above the flow of the design flood. The estimated Federal cost, revised in 1951, is $4,726,000, and the estimated non-Federal cost is $2,110,000. The existing project was authorized by the Flood Control Act approved June 22, 1936. Local cooperation. See pages 4-5 for requirements. Resolutions by the city of Hutchinson, agreeing to meet the requirements were submitted by the city under the dates of March 16 and 30, 1945, and were approved by the Secretary of War on July 4, 1945. The city of Hutchinson has acquired rights-of-way for only the portion of the project that would protect the city proper, and right of entry has been granted to the United States Govern- ment for construction of that portion. Right of entry has not been furnished for remainder of the project including the Island Park Subdivision ring levee, the rural area loop levee, and the right bank levee adjacent to the city of South Hutchinson. Operations and results during fiscal year. Preparation of con- tract plans and specifications for construction of levees was continued. Negotiations with railroad companies for alteration of their facilities within the area were continued. The cost during the fiscal year was $9,019.86 and the expendi- tures were -$944.03, all for new work. Condition at end of fiscal year.

WICHITA AND VALLEY CENTER, ARKANSAS RIVER, KANS. Location. The work covered by this project is located on the Arkansas River, and Little Arkansas River and Chisholm Creek, tributaries of the Arkansas River, in the immediate vicinity of Wichita and Valley Center, Kans. (See U. S. Geological Survey map for Wichita (Kans.), quadrangle, scale 1:125,000.) Existing project. The plan of improvement provides protection to people, city property and environs against floods from Chisholm FLOOD CONTROL-TULSA, OKLAHOMA, DISTRICT 1115 Creek, the Little Arkansas River, the Arkansas River, Big Slough and Cowskin Creek. Under the plan, Little Arkansas River will be diverted into the Arkansas River by means of a floodway beginning at a point about 2 miles northwest of Valley Center and extending southward to the Arkansas River (at river mile 785.7) about 9 miles northwest of Wichita. The flows of Chisholm Creek and its middle and west branch tributaries will be collected by a system of levees and channels north of Wichita and diverted across the Little Arkansas River into the Arkansas River (at mile 780). Each of the above leveed diversion channels are about 3 miles in length. The combined flows of the Little Arkansas River, Chisholm Creek and Arkansas River will be confined and diverted to the west of the city by a floodway, with existing stream channels being utilized to carry flood flows to the limit of their existing capacity. This floodway will begin at a point about 3.1 miles downstream from the Kansas State Highway 96 river crossing and will provide a channel having a normal bottom width of 80 feet and an average depth of 10.9 feet. Levees flanking the floodway will, in general, be spaced 900 feet center to center with an average height of 8.5 feet and a crown width of 8 feet or more. From the Arkansas River the floodway would extend southwest 2 miles to intercept Big Slough, along Big Slough for 5 miles, thence south and southeast 2.5 miles to intercept Cowskin Creek, along Cowskin Creek for 2 miles, thence east, and southeast about 5 miles entering the Arkansas River approximately 1 mile.north- west of Derby, Kans. (at river mile 760). Existing levees and drainage canals will be enlarged strengthened, or rectified as may be required. The completed system will include five control struc- tures and will provide about 91.2 miles of levee with a minimum of 3 feet freeboard above the flow of the design flood. The estimated Federal cost, revised in 1951, is $13,731,000 and the estimated non-Federal cost is $5,930,000 (June 1951). The existing project was authorized by the Flood Control Act, approved June 22, 1936. (See H. Doc. 308, 74th Cong., 1st sess., which contains the latest published maps.) Local cooperation. See pages 4-5 for requirements. The city of Wichita has furnished assurances of local cooperation for the entire project which were approved by the Secretary of War on February 25, 1946. Local cooperation requirements are fulfilled for the completed portion of the project consisting of the Wichita Drainage Canal and diversion of East Branch of Chisholm Creek. Right of entry for construction of the Big Slough-Cowskin flood- way portion has been granted, and local interests are in the process of acquiring rights-of-way for other phases of construc- tion. Operations and results during fiscal year. Negotiations cover- ing necessary relocation or alteration of railroad facilities were continued and construction operations covering the lower portion of the project were continued under continuing contracts. The cost during the fiscal year was $378,521.30 for new work. The expenditures were $395,256.36. 1116 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 Condition at end of fiscal year.

PENSACOLA RESERVOIR, ARKANSAS RIVER BASIN, OKLA. Location. Pensacola Dam is located on the Grand (Neosho) River, 77.0 miles above its mouth, and adjacent to the town of Disney, Mayes County, Okla. (See U. S. Geological Survey maps for Pryor, Wyandotte, Vinita (Okla.), and Siloam Springs (Ark.), quadrangles, scale 1:125,000.) Existing project. During the fiscal year 1941 the Grand River Dam Authority, an agency of the State of Oklahoma, under a license dated July 26, 1939, issued by the Federal Power Commis- sion, completed the construction of a reservoir for flood control and hydroelectric power at the Pensacola site in the Arkansas River Basin. The dam is of the concrete, multiple-arch type, 6,565 feet long and 147 feet above the stream bed. The existing dam and reservoir provides 1,653,000 acre-feet of storage to top of power pool and 245,000 acre-feet of flood-control storage. The flood-control storage lies between elevations 745 and 750. How- ever, under the terms of the Federal Power Commission license, the dam and appurtenant structures were constructed to a height which would allow storage of flood waters to elevation 755 (Pensa- colo datum) at the Pensacola Dam, when necessary lands or rights-of-way were acquired by the Federal Government. The Flood Control Act approved August 18, 1941, modified the general comprehensive plan for flood control and other purposes for the Arkansas River Basin to include the Pensacola, Markham Ferry, and Fort Gibson Reservoirs in the Grand (Neosho) River Basin in Oklahoma and Missouri, in accordance with recom- mendations of the Chief of Engineers in House Document No. 107, Seventy-sixth Congress, first session. The improvements recommended in that document included a reservoir for flood control at the Pensacola site which provided for 960,000 acre-feet of flood-control storage. FLOOD CONTROL-TULSA, OKLAHOMA, DISTRICT 1143 The existing project now provides for making available 278,- 000 acre-feet of flood-control storage between elevations 750 and 755 (Pensacola datum), in addition to the storage provided in the project as constructed by the Grand River Dam Authority. Flowage easements for certain portions of the necessary lands have been acquired by the Federal Government through the Southwestern Power Administration, Department of the Interior, and the Federal Works Agency. The acquisition of additional flowage easements necessary for operation of the reservoir to elevation 755 (Pensacola datum) at the Pensacola Dam is esti- mated to cost $1,555,000 (June 1951).

RED RIVER LEVEES AND BANK STABILIZATION IN ARKANSAS BELOW DENISON DAM Location. The improvements covered by this project within the Tulsa District are located along the left bank of Red River from the vicinity of Index, Ark. (Tex.), downstream to Fulton, Arkansas. Existing project. The plan of improvement provides for modi- fication of existing and authorized Federal and non-Federal levees and other flood-control improvements, and for the protection of the valley of the main stem of Red River by construction of revet- ment and other channel stabilization work where needed to pro- tect the banks from caving at locations where levee set-backs are impossible or uneconomical and to prevent the disruption to transportation facilities when threatened by caving banks. The existing work to date on the project has been confined to the vicinity of Index, Ark. (Tex.), and includes construction of about 5,500 linear feet of revetment along the left bank of Red River adjacent to the existing non-Federal levee of the Ogden Levee dis- trict where construction of a set-back levee was impractical. The estimated Federal cost for this bank protection, revised in 1951, is $207,000 and non-Federal costs, exclusive of costs to Ogden Levee district, are $20,000 cash contributions, of which $10,000 was furnished by the Arkansas State Highway Commis- sion and $10,000 by the Southwestern Gas & Electric Co. The Kansas City Southern Railroad furnished and hauled riprap stone without charge to the equivalent of a contribution of $50,- 000. The existing project was authorized in the 1946 Flood Control Act as set forth in House Document 602, Seventy-ninth Congress, Second Session. Local cooperation. All land, rights-of-way, easements and spoil areas required for the bank protection adjacent to Ogden levee have been furnished by the Ogden Levee District, Ark. Operations and results during the fiscal year. A total of 32,733 cubic yards of dumped riprap, revetment work, was placed on the left bank of the Red River adjacent to Ogden Levee (river mile 491.5). This work was completed, by contract, on December 20, 1166 REPORT OF CHIEF OF ENGINEERS, U. S. ARMY, 1951 1950, utilizing Federal funds and funds contributed by the Arkan- sas State Highway Commission and by the Southwestern Gas and Electric Company. The Kansas City Southern Railway furnished and transported riprap stone without charge; equivalent to a cash contribution of $50,000. The cost during the fiscal year was $153,461.40 from regular funds and $20,000 from contributed funds. The expenditures were $149,102.46 from regular funds and $20,000 from con- tributed funds. Condition at end of fiscal year. A field inspection of the com- pleted works was made on February 28, 1951, following a rise on the Red River. It was found that damage had occurred to the revetment at one point, as a result of the undercutting action of the river current. The total costs and expenditures to the end of the fiscal year were $178,956.65 of which $158,956.65 was from regular funds and $20,000 was from contributed funds. Proposed operations. There was no unexpended balance on June 30, 1951. However, from an allotment of $48,000 during fiscal year 1952, repairs to the existing works will be effected, by contract. No additional funds can be profitably expended in fiscal year 1953 covering this segment of the project and no stabilization work is scheduled for the remaining portions of the authorized project within the Tulsa District.
