Location. In Jefferson Parish, La., and extends about 37 miles generally southerly from junction of 0 ulf Intracoastal Waterway and Bayou Barataria near Lafitte Post Office. From its origin it extends ndotherly through Bayou Barataria, Bayou Dupont, a andcut (known as Dupre Cutoff) through marsh area, ayou Cutler, Bayou St. Denis, and Barataria Bay to also end of Bayou Rigaud. At its southerly terminus it connects with Barataria Pass and through that pass with the Gulf of Mexico. (See Coast and Geodetic Survey Charts 1050, 1116, and 1237, Geological Survey maps Barataria, Bay Dogris, Wilkinson Bay, and Barataria Pass.) Previous project. For details see page 562 of Annual Report for 1963. Existing project. A channel about 37 miles long with a 12-foot depth and 125-foot width from its beginning at Gulf Intracoastal Waterway to Grand Isle, La., following route of previous project to mile 15.5 in Bayou St. Denis; thence by a relocated channel along western shore of Barataria Bay and through Barataria Pass to 12-foot depth contour in the gulf, with an extension of project to include westerly 4.3 miles of Bayou Rigaud. Normal range of tide is 30 inches at mouth and 6 inches at head. Elevation of water surface near mouth, due to hurricanes, has been over 6 feet. Existing project, adopted by 1958 River and Harbor Act (H. Doc. 82, 85th Cong., 1st sess., contains latest published map), was completed at a cost of $1,499,648. Local cooperation. Fully complied with. Terminal facilities. Six privately owned wharves at Lafitte; three privately owned facilities at Grand Isle; and wharfage in Bayou Rigaud at Grand Isle constructed by shrimping industry are available to all boats without charge. About 7 miles below Lafitte there is an extensive oil terminal for transferring production of Lafitte field to barges. Adjacent to Bayou Barataria and along Bayou Rigaud adequate sites are available for future use. Operations and results during fiscal year. Condition and operation studies were conducted by hired labor. Restoration of project channel, by contract initiated in previous fiscal year,. was completed April 28, 1968, with 1,457,923 cubic yards excavated during the year as follows: The dredge Tchefuncta removed 125,443 cubic yards from Bayous Villars and Barataria at the entrance Y to the Gulf Intracoastal Waterway; the dredge Paul F. Jahncke removed 441,566 cubic yards between miles 7.75 and 10.6; the dredge Conical removed 453,779 cubic yards between miles 3.90 and 7.75; the dredge Tennessee removed 437,135 cubic yards from Bayou Rigaud between miles 0.70 and 4.34. Condition at end of fiscalyear. Construction was initiated in May1960 and completed in November 1963. Total cost of existing project to June 30, 1969, was $2,871,555, of which $1,499,648 was for new work, and $1,371,907 for maintenance. Controlling depths, 387 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 mean low gulf: (Apr. 1969) Gulf Intracoastal Waterway to gulf, 12 feet; bar channel, 14 feet; (Apr. 1969) Barataria Pass to Buoy 8, 11 feet; to Buoy 18, 12 feet. 4. BAYOU GROSSE TETE, LA. Location. This bayou rises in Pointe Coupee Parish, La., and extends generally southeast, entering Bayou Plaquemine 8 miles below Plaquemine lock. (See Corps of Engineers, Mississippi River Commission alluvial valley map, and New Roads, Fordoche, Osca Bayou, and Grosse Tete quadrangles.) Existing project. This provides for improving the stream for a distance of 29 miles from its mouth to a point 5 miles above Maringouin, La., by removing snags and trees and by dredging a channel 60 feet wide on bottom and 5 feet deep at mean low water. Mean low water is 2 feetabove mean low Gulf level. Under ordinary conditions the mean range of tide is about 3 inches at the mouth and nothing at the head, and the extreme range about 6 inches at the mouth. The variation of water surface due to flood conditions may be from 2 to 8 feet. Cost of new work, completed in 1916, was $29,392. Portion remaining has been classified inactive. The existing project was adopted by the River and Harbor Act of July 25, 1912 (H. Doc. 348, 62d Cong., 2d sess.). The latest published map is printed opposite page 2540 of the Annual Report for 1917. Terminal facilities. There are no wharves on the bayou. The banks are firm and high. The boats operating on the stream unload their cargoe.s at any desired point, carrying the freight by hand into the stores, which are generally on the bank of the bayou. The facilities are considered adequate for existing commerce. Operations and results during fiscal year. Clearing and snagging of the bayou was accomplished by hired labor during the period October 28, 1968, to March 14, 1969. The work consisted of removing fallen trees, logs and other debris from the channel and both banks between miles 0 and 24. Condition at end offiscalyear. A channel 5 feet deep at mean low water, and 60 feet wide on the bottom was completed in 1914 to mile 10.3, and from that point to the head of the project a 5- by 40-foot channel was dredged in 1916. Enlargement of the channel to 60 feet above mile 10.3 has been delayed due to lack of spoil disposal areas and this portion has been classified as inactive. Controlling depths, mean low gulf: (Aug 1968) miles 0 to 2.1, 12 feet; (Aug. 1958) miles 2.1 to 4, 4.5 feet; miles 4 to 11, 3 feet; and miles 11 to 14.5, 2.5 feet. 5. BAYOU LAFOURCHE AND LAFOURCI E JUMP WATERWAY, LA. Location. Prior to 1902 Bayou Lafourche was an outlet of Mississippi River, its head being at Donald' sonville, La., 80 miles above New Orleans. It floSw generally southerly 107 miles to Gulf of Mexico. (See Coast and Geodetic Survey Charts 1116 and 127; Mississippi River Commission alluvial valley ma; Donaldsonville, White Castle, Napoleonville, Thi bodaux, and Lac des Allemands quadrangles; and Geological Survey maps Houma, Cutoff, Lake Felicity, Mink Bayou, Leeville, and Belle Pass quadrangles.)

Condition at end of fiscal year. Construction of existing project was initiated in fiscal year 1939 and is 17 percent complete. Dredging between Larose, La., and Gulf of Mexico,was completed in 1939 and that segment between Lockport and Napoleonville, La., is in an inactive status due to lack of right-of-way and spoil area. Jetties at mouth of Belle Pass were completed in 1939, and later damaged by storm action, which required placement of additional stone adjacent to both sides of steel sheet pile jetties in 1940, and repair and extension of jetties in 1941. During fiscal year 1948 stone jetties were repaired and extended inland about 700 feet from shoreline; and steel sheet pile section was strengthened for about 250 feet gulfward of stone jetties, by placement of stone on both gulf and bayou sides. On May 31, 1949, an automatic tide gage for recording hurricane and storm tides was installed. Modification of July 14, 1960, was initiated in February 1963 and is 13 percent complete, with 12- by 125-foot channel completed in September 1963 from Leeville to 12-foot contour in Gulf of Mexico, and the 9- by 100-foot channel completed in August 1966 from Golden Meadow to Leeville and the 9- by 100-foot channel from Golden Meadow to Leeville completed in August 1966.

(See U. S. Coast and Geodetic Survey Chart No. 1116 and U. S. Geological Survey quadrangles Lake Arthur and Gueydan.) The stream is 50 to 110 feet wide and about 60 miles long. The section under improvement is 14 miles long, measured through the proposed cutoffs, and extends from the mouth to the Southern Pacific Railroad bridge at Riceville, La. The stream is tidal. The watershed is about 285 square miles. The discharge at low water is about 40 second feet. Existing project. Provides for the removal of obstructions from its mouth to the Southern Pacific Railroad bridge at Riceville, La., and for dredging 10 cutoffs, aggregating 1,765 feet in length, reducing the distance from the mouth of the bayou to the bridge to about 14 miles. No channel dimensions were specified. Under ordinary conditions the mean range of tide is about 5 inches at the mouth and nothing at the head, and the extreme range about 10 inches and nothing, respectively. During severe rains there is at times a rise of 6 feet. New work under the project was completed in 1923 at a cost of $33,355. The existing project was adopted by the River and Harbor Act of July 25, 1912 (H. Doc. 609, 61st Cong., 2d sess.) The latest published map is printed opposite page 2466 o0f the Annual Report for 1916. Local cooperation. Fully complied with. Terminal facilities. There are no terminal facilities on the bayou other than a warehouse and a sall wharf at mile 6, which is used principally for shiP ping rice. Landings at the pumping plants are gened ally made on the banks. The terminals are considered adequate for existing commerce. There are no public wharves open to use of all carriers on equal teras. (For a full description of terminal facilities, see Doc. 652, 66th Cong., 2d sess.) Operations and results during fiscal year.

CYPRESS BAYOU AND WATERWAY BETWEEN JEFFERSON, TEX., AND SHREVEPORT, LA. Location. Cypress Bayou rises in northeast Texas and flows southeasterly to Caddo Lake, through this lake to Big Willow Pass, and through Big and Little Willow Passes, Soda Lake, Twelve Mile.Bayou, new diversion canal, and Cross Bayou to Red River at Shreveport, La., a distance of about 132 miles. (See Geological Survey State maps and quadrangle maps.) Cypress Bayou proper ends where it enters Caddo Lake, but the name is frequently applied to the whole waterway described above. Existing project. Dredging and straightening channel, removing obstructions, and clearing banks for 66 393 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 miles from Red River at Shreveport, to Jefferson, and a 3,400-foot long, fixed, on pile foundation, dam at foot of Caddo Lake, La. and Tex., about 23 miles above mouth of Jefferson-Shreveport Waterway and 2 miles below Mooringsport, La. Dam was completed December 21, 1914, at cost of $100,553. Cost of new work, excluding modification of August 13, 1968, was $202,817. Reconstruction of dam authorized by 1965 Flood Control Act. (See report under flood control feature.) (See table 11-B for authorizing legislation.) Local cooperation. None required. Terminal facilities. None at Shreveport, La. Two publicly owned brick warehouses, 50 by 150 feet, at Jefferson, Tex., and three oil company facilities at Mooringsport, La., a covered dock, 60 by 60 feet opened to all small boats, a pipe rack not decked, and boatways. Warehouse at Jefferson has not been used for several years, since no commerce has moved in that vicinity. Facilities considered adequate for present commerce. Operations and results duringfiscalyear. None. Condition at end of fiscal year. Dam at foot of Caddo Lake was completed in December 1914, completing project. Its construction and maintenance insure a 4-foot navigable depth at low water from that point to Jefferson, head of navigation, but prevent possible navigation to Shreveport, except for such light draft boats as may pass over dam at high stages. Below dam, navigation is largely dependent upon backwater from Red River. A stage of from 15 to 24 feet on Red River gage at Shreveport, depending on runoff from Cypress Bayou drainage area, is necessary to provide a 4-foot depth up to dam. Such stages are short in duration and irregular in occurence. A reconnaissance survey, May 1961, with 0.7 foot of water running over crest of dam, showed following controlling depths from Mooringsport, La., to Jefferson, Tex.: Caddo Lake, mile 34 to 35 (at channel Marker III), 5.7 feet; Cypress Bayou, mile 39 to 40 (Government cut), 5.6 feet; mile 65 to 66 (head of navigation), 5.8 feet. Replacement of Caddo Dam, authorized by Flood Control Act of 1965 (S.Doc. 39, 89th Cong., Istsess.), is under construction and is reported separately as Caddo Dam, La. 13.

(See Table I1 -E for estimated cost of new work.) In addition, the Coast Guard is to provide navigation aids at an estimated cost of $94,000. Construction of bulkheads and jetties at Lake Borgne and Chef Menteur, La., is considered inactive and excluded from foregoing cost estimate. Estimated cost (1956) of this item is $440,000. Construction of a double-leaf bascule, four-lane highway bridge provided for under this project has become unnecessary because portion of project over which bridge was to be constructed was incorporated in project 'Mississippi River-Gulf Outlet' which provides for a larger bridge. Bayou Sorrel and Bayou Boeuf locks were constructed and are being maintained and operated with flood control, Mississippi River and tributaries, funds. Therefore, construction, maintenance, and operation costs are not included in approved estimates referred to before. Locks on Gulf Intracoastal Waterway in New Orleans District are set forth in table at end of chapter. (See also Table 1 I1-B for authorizing legislation.) Local cooperation. Algiers lock and canal: All assurances required for construction were furnished. Local agency has failed to convey all fee and easement tracts with acceptable title evidence to the United States. However, authority has been received to accept the interests conveyed as best available from local agency with the understanding that the United States rely upon assurances of local cooperation should any claims against the United States occur as a result of failure of local agency to complete transfer of title. Plaquemine-Morgan City alternative route: All assurances required for construction were furnished. Title by United States has been acquired to all but 35 tracts, for which local agency failed to comply fully with curative requirements in title certificate. Authority was given to accept the tracts conveyed as best available from local interests and to rely upon assurances of local cooperation furnished by local agency should any claims against the United States occur as a result of failure of local agency to complete transfer of title. Modification authorized by River and Harbor Act of 1962: Local interests must furnish lands, rights-ofway, and spoil-disposal areas for enlargement and future maintenance of project, make alterations to utilities; construct, maintain, and operate all bridges desired in connection with bypass channel around Houma, La.; and hold the United States free from damages. Assurances were requested in April 1963; however, none of 11 local agencies involved has furnished assurances requested. Main objection to participation is requirement that local interests be responsible for alteration of utilities. Assurances of local cooperation for the replacement of the existing Vermilion 397 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Lock were requested of the Vermilion Parish Police Jury on September 10, 1968. The Police Jury, by letter dated April 9, 1969, has indicated its willingness and capability of providing the requirements of local cooperation for the project, when funds are available. Terminal facilities. Extensive terminal and transfer facilities, suitable for receiving and shipping commodities by barge, are available at principal cities in Louisiana; namely, New Orleans, Baton Rouge, Harvey, Morgan City, and Lake Charles. Facilities at New Orleans are on Inner Harbor navigation canal. Canal and facilities were leased from Board of Commissioners, Port of New Orleans, April 1, 1944, and are now operated by the United States, toll free, 24 hours per day. At Morgan City, on Atchafalaya River, there are two large and three small wharves open to all without charge. Otherwise facilities are confined to privately owned piers, wharves, or oil docks. Facilities considered adequate for existing commerce. Operations and results duringfiscal year. New work by hired labor: Surveys and engineering studies were initated for preparation of general design memorandum for replacement of Vermilion lock. Maintenance by hired labor: Real estate activities, condition and operation studies, non-cooperative stream gaging, investigation and surveys, condition surveys, and channel patrol continued. Locks, bridges, and waterways were operated and maintained. Fender systems were repaired at Calcasieu, Harvey, Inner Harbor navigation canal, Port Allen, and Vermilion locks. Bulkhead, residence, and roads were repaired at Vermilion lock. Algiers lock was repaired and sector gates painted between September 9 and October 18, 1968, during which time the lock was closed to navigation. The waterway from mile 15.0 to 29.5 west of Harvey was cleared by the removal of debris and sunken logs during the period February 10 to March 28, 1969. Maintenance by contract: New gates were procured for Vermilion lock and delivered to lock site on June 2, 1969. At Inner Harbor navigation canal lock, mooring dolphin No. 2 was removed and new dolphin constructed. Work was initiated November 11, 1968, and substantially completed on June 30. The northwest dolphin was repaired between July 5 and 25, 1968. Dredging included restoring 7.2 miles of the main stem channel from mile 1.7 to mile 58.8 west of Harvey during the period December 4, 1968, to March 22, 1969, by the dredges Tchefuncta and Paul F. Jahncke. Shoal was removed from the forebays at Inner Harbor navigation canal and Port Allen lockS. The dredge Vicksburg removed 71,550 cubic yards between July 17 and 23, and the dredge Arkansas re moved 25,620 cubic yards between October 14 aed 17, 1968, from Inner Harbor lock forebay. dredge Holland removed 241,122 cubic yards betwee July 18 and August 3, 1968, and 97,500 between June 14 and 21, 1969, from Port Allen lock forebay Dredging below Bayou Sorrel lock consisted of le moving 25,703 cubic yards by the dredge Holl during the period August 4 to 8, 1968. Levee work consisted of raising the east levee alo91 Algiers alternate connection by the placement of l.a 733 cubic yards of embankment during the pe July 1, 1968, to June 13, 1969. Condition at end offiscalyear. Construction was il tiated July 1929 and project as modified is 61 percent complete. For information on completion of segments o a terway, see 1965 Annual Report, pages 523 and 524. Work remaining to complete the project consists nofr enlarging waterway as provided by 1962 River aCo Harbor Act, and replacement of Vermilion lock.

ERMENTAU RIVER, BAYOU NEZPIQUE, AND BAYOU DES CANNES, LA. Loocation. Mermentau River is formed by junction eraayous des Cannes and Nezpique, 2.25 miles above Iern~entau, La., flows southwesterly, and empties the Gulf of Mexico. Bayou Nezpique rises in ageline Parish, flows southerly and empties into Mermentau River. Bayou des Cannes rises in Evangeline Parish, flows south-southwesterly and empties into Mermentau River. (See Coast and Geodetic Survey Charts 1116and 1278, and Geological Survey maps, Evangeline, Hathaway, Mermentau, Jennings, Lake Arthur, Gueydan, Thornwell, Latania Lake, Catfish Lake, Grand Cheniere, and Bayou Labauve quadrangles.) Previous project. For details see page 637, 1961 Annual Report. Existing project. Provides a 12- by 125-foot channel in Mermentau River from Gulf Intracoastal Waterway to Lake Arthur; a 12- by 200-foot channel through Lake Arthur and a 12- by 125-foot channel from upper end of Lake Arthur to junction of the Mermentau River and Bayous Nezpique and des Cannes; replacement of existing Lake Arthur highway bridge over Mermentau River with new bridge constructed to current highway standards and with vertical and horizontal clearances of 50 and 200 feet, respectively; and enlargement and realinement of Bayous Nezpique and des Cannes, to provide a 12- by 125-foot waterway from Interstate Highway 10 to the Mermentau River. Mean range of tide on Mermentau River near mouth is 10 inches and near head about 3 inches, extreme ranges being 14 and 5 inches, respectively. Variation of water surface near mouth may be as much as 7 or 8 feet, due to hurricanes on gulf and near head from 8 to 12 feet, due to freshets. Under ordinary conditions, range of tide on Bayous Nezpique and des Cannes is about 3 inches at mouth and nothing at head. Estimated cost for new work (July 1969) is $4,850,000 Federal and $1,286,000 non-Federal, including a cash contribution of $610,000. In addition the Coast Guard is to provide navigation aids at a cost of $51,000. Existing project authorized by 1965 River and Harbor Act (H.

Local interests shall agree to: provide all lands for construction and maintenance and spoil-retaining works or the costs of such works; hold the United States free from damage due to the project; design and construct a replacement highway bridge at Lake Arthur, La.; bear 17.1 percent of the costs ($610,000 cash contribution), and operate and maintain the bridge; provide and maintain terminal facilities; and accomplish and maintain all modifications to utilities. The improvement of the Mermentau River or of Bayou Nezpique or Bayou des Cannes, may be undertaken independently as the local cooperation therefor 399 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 is provided, concurrent with, or subsequent to, replacement of the Lake Arthur highway bridge. Assurances have been furnished by the Acadia and Jefferson Davis Parish Police Juries and the Louisiana Department of Highways. The Vermilion Parish Police Jury, by letter dated April 9, 1969, gave assurance of its capability and willingness to provide the requirements of local cooperation for that portion of the project in Vermilion Parish, whenfunds are available. The Cameron Parish Police Jury, in its letter of April 18, 1969, reaffirmed its previous position that it did not desire to execute assurances for the project. Terminal facilities. Several small, privately owned wharves at Grand Cheniere and a public terminal at town of Lake Arthur. Privately owned terminals for transferring crude oil to barges are: One on Lake Arthur near town of Lake Arthur; one on Mermentau River near town of Mermentau; two on Bayou Nezpique near Jennings; and four on Bayou des Cannes; one near Evangeline, one at Mermentau, and two near Jennings. Facilities are considered adequate for existing commerce. Operations and results during fiscal year. Hired labor forces and an architect-engineer firm continued studies and investigations for preparation of general design memorandum, which is essentially complete. Agreement was reached with the Louisiana Department of Highways on the draft ofthe reimbursable contract for the design and construction of the Lake Arthur, La. bridge replacement. Condition at end of fiscal year. Construction not initiated. 18. MERMENTAU RIVER, LA. Location. Work covered by this project is 35 to 70 miles southeast of Lake Charles, La., along lower Mermentau River below Grand Lake, mile 25, to Gulf of Mexico; Inland Waterway from Vermilion Bay to White Lake, White Lake to Grand Lake, and from Schooner Bayou to Intracoastal Waterway-gulf section (Schooner Bayou cutoff); North Prong of Schooner Bayou; and waterway from White Lake to Pecan Island, La., and artificial canal, extending from 5-foot depth contour in White Lake, almost due south for about 1.8 miles to Pecan Island. (See Coast and Geodetic Survey Charts 1277 and 1278, and Geological Survey maps.) Existing project. Flood control, navigation, irrigation, and salinity control in coastal marsh of lower Mermentau River Basin and channel enlargement of 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 floodflows; con" struction of a sector gated control structure at Catfish Point, mile 24 above mouth of Mermentau River, for discharge of floodflows and control of tidalflows and salt-water intrusion in Mermentau River; channel enlargement and realinement of Inland Waterway from Vermilion Bay to White Lake, 12.04 miles, and from White Lake to Grand Lake, 6.14 miles, to a minimu' section of 3,000 square feet below mean low gulf level or interflow between lakes and discharge of floodflows; construction of a sector gated control structure in enlarged channel immediately north of abandoned Schooner Bayou lock reservation for discharge.of floodflows and control of tidalflows and salt-water in trusion; channel enlargement of North Prongof Schooner Bayou and Schooner Bayou cutoff, 6.69 miles, to 6 by 60 feet, mean low gulf level, for navigation purposes; and maintenance of existing 5- by 40 foot, mean low gulf level, waterway from White Lake to Pecan Island, La., 1.8 miles long, for navigation. In addition, project provides for incorporation of tfal section of project, 'Inland Waterway from Franklia' La., to Mermentau River,' west of Vermilion Bay, a waterway that includes Schooner Bayou lock. Project was reclassified as an 'Operation and Maintenance' General' project under category, 'Navigation (LockS'ief Dams, Reservoirs, and Canals)' by authority of Chlef of Engineers, April 23, 1956.

Plane of reference through New Orleans and below is mean low gulf. General plan of improvement of Southwest Pass provides for constructing pass to uniform cross section with about 1,420-foot surface width by means of jetties, spur dikes and bulkheads; for channel improvement by dredging and retaining dredged material between dikes, bulkheads, and jetties; for dredging a channel through outer bar inclining to left of jetty axis; for construction of small revetted openings through narrow portions of banks of pass for purpose of strengthening these banks; for closure of minor outlets not required for maintenance of banks; for construction of sills to prevent enlargement of Jump and Cubits Gap; for dredging to elevation minus 40 feet in river 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 width of river above Head of Passes; for construction of a submerged deflecting dike above Head of Passes; and for other minor work. East jetty is about 24,950 feet long and west jetty 19,- 699 feet. Jetties are composed of a substructure of brush mattresses, originally built to about elevation of mean low gulf, surmounted with a superstructure of concrete blocks and large riprap and for stone rubble mound of core and cover stone. Spur dikes are complsed of cribwork of round piling filled with willows and stone, or with a curtain of round piles along upstream face. General plan of improvement of South Pass provides for construction and maintenance of jetties and spur dikes; maintenance of a sill across Pass a Loutre; for dredging a channel 40 feet deep and no specified width through shoals of river between Cubits Gap and Head of Passe,, 3.5 miles, and for seaward 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 head of South Pass to bottom elevation 401 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 of minus 45 feet and revetment of new bank line and construction and maintenance of east and west headland structure at head of Passes. East jetty foundation is 12,070 feet long; inner east jetty is 11,170 feet long; west jetty is 7,820 feet long; and inner west jetty is 4,710 feet long. Jetties are composed of a substructure of brush mattresses surmounted by a superstructure of stone and/or concrete blocks and large riprap. Spur dikes are composed of cribwork of round piling filled with willows and stone. Plane of reference is mean low gulf. Variation of water surface is 16 inches at mouths and 10 inches at heads of the passes, due to tides. Extreme range of tides at mouths of passes due to hurricanes is about 10 feet. At New Orleans extreme range of water surface is about 20 feet due to floods. At Baton Rouge extreme range is about 45 feet due to floods. Estimated cost of existing project (July 1969) is $34,227,000 Federal and $18,000 non-Federal. In addition, Coast Guard is to provide navigation aids at an estimated cost of $28,900. (See table 11-B for authorizing legislation.) Local cooperation. None required, except for modification of project in connection with Mississippi River-Gulf Outlet, which is reported separately. Terminal facilities. Some 100 piers, wharves, or docks serve Port of New Orleans. Most wharves on east or left bank parallel riverbank forming nearly a continuous covered quay about 10 miles long. Public wharves controlled by Board of Commissioners, Port of New Orleans (the Dock Board), cover 62 percent of improved waterfront. These facilities include a shipside grain elevator, general cargo and cotton wharves, fruit landings, bunkering facilities, terminal warehouses, railroad terminals, marine railways, and drydocks and.are considered adequate for present commerce. (For further details see Port Series No. 20, 'The Port of New Orleans, La.' 1958.) A foreign trade zone is located in Port of New Orleans. City of Baton Rouge has a reinforced concrete dock for deep sea vessels with mechanical-handling facility. Attached to downstream end of wharf is a floating wharf boat 23 1 by 40 1/2 feet, of 2,000-ton capacity. Facilities are served by a transfer boat and municipal terminal having a capacity of 40 cars per day. Private terminals for handling oil, grain, bauxite ore, and other products are at points on both sides of river between New Orleans and Baton Rouge. Facilities are considered adequate for existing commerce. (For further details, see 'Port Facilities' included in 'Flood Control and Navigation Maps of the Mississippi River, Cairo, Ill., to the Gulf of Mexico, Louisiana,' published in 1968 by Mississippi River Commission, and Port Series 14No 19, Vol. 1, 'Port St. Joe, Fla., Pensacola, Fla., BatOl Rouge, La., Panama City, Fla., Fascagoula, Miss., Lake Charles, La., Gulfport, Miss.,' revised 1957.) Operations and results during fiscal year. New work: Work remaining is construction of lateral permeable pile dikes, miles 1.8 to 2.8 east bank, miles 10.1 t 14.4 west bank, and miles 19.1 to 20.2 west bank, to stabilize Southwest Pass and prevent further bank erosion by high river stages and wave action fro passing ships. Construction is deferred to await results of river action since completing the 40f0oof channel. Maintenance: (a) Baton Rouge to New Orlean U.S. dustpan dredge Jadwin removed 4,826,395 cubic yards at five crossings. (See table 1 1-G at end of chap' ter on maintenance: Baton Rouge to New Orleans.) Reconnaissance surveys were made of Red Eye , Medora, Granada, Bayou Goula, Alhambra, Philadelphia, Belmont, and Fairview Crossings by hired l bor, as required. Maintenance by hired labor: dredge Jadwin $580,500 and surveys, $25,100. (b) New Orleans Harbor: Leased dredges Tchefuncta, Vicksburg, Arkansas, and Tennessee removed 2,165,833 cubic yards within harbor beyon 100-foot line from face of wharves along left ban from the Henry Clay Avenue wharf intermittently downstream to and including the Murphy Oil Corp wharf Meraux, La. (See Table 1 I1-H on maintenance: New Orleans Harbor.) On November 17, 1947, contract was entered into with Board of Commissioners for the Port of New Of leans, for a more efficient and expeditious use o dredges to provide navigable depths in project cha . nel in Port of New Orleans and within 100-foot licit along left bank wharves. This contract was renewed in 1967 for a period of five years. During fiscal year u der this reciprocal agreement, 87,875 cubic yarot were removed by leased dredge, from within 100.fo line, and 124,432 cubic yards were removed by the Board of Commissioners outside the 100-foot line. River traffic control signal lights to govern move* ment of vessels within Port of New Orleans during flood stages were operated during periods: February 5, 1969, to March 19, 1969; and April 8, 1969, to Jun 30, 1969.

(See Table I I-L at end of chapter on average ieCharges in percentages of total discharge of river at d of Passes during flood cycles; also see Table 1 1- on channel conditions on June 30, 1969.) Condition at end of fiscal year. The existing project Gulpercent complete, exclusive of Mississippi Riverulf Outlet. Orla) Baton Rouge to New Orleans Harbor, and New leans to Head of Passes: The Coast Guard cutter "hire Alder, sank December 7, 1968 at mile 195.2 tP, is not considered a hindrance to navigation at ethpree sent time. Survey of June 24, 1969, shows 50 feet of water over the vessel. Removal by private interests of sunken vessels Genevieve and Letitia Lykes nurrican 'Betsy') from channel on left descending nk at mile 115 AHP continued until April 5, 1969, en partially raised Genevieve Lykes sank below the water surface. Due to river stages further attempt to raise vessel was discontinued. The sunken dredge Indiana, on right descending bank, mile 102.4 AHP, is not considered a 'hindrance to general navigation at this time. The S/S Union Faith, which sank April 7, 1969, at mile 95.3 AHP, just below the greater New Orleans Bridge in mid-channel, is an obstruction to navigation. Private interests are expected to submit plans for removal by September 1969. Private interests removed sunken barge at mile 46 AHP on January 30, 1969. The Governor Nicholls traffic control tower in the Port of New Orleans will be raised in elevation so that light operators can see above ships that dock in front of the structure. Annual maintenance is required after each high water period. Dredging is in progress on crossings between Baton Rouge and New Orleans, by U.S. dredge Jadwin and in New Orleans harbor by leased plant. A natural channel of project dimensions or greater was available between New Orleans and Head of Passes. (b) Southwest Pass: Annual maintenance is required after each high water period and is in progress by contract dredge and U.S. dredge Langfitt. East and west jetties, east and west headland structures, permeable pile dikes, and parallel stone dikes require continued maintenance due to settlement and wave action from open sea and passing ships. A contract for repairs to East Jetty was completed on February 21, 1969, after placing 52,941 tons of stone. Plans include repairs to West Jetty in fiscal year 1970. Continued watch and study is required for protection and preservation of narrow existing land area between Southwest Pass and West Bay in Gulf of Mexico. Parallel stone dikes preventing bank erosion from passing traffic and placing dredge spoil on bank are proving most effective. So as to also explore plans for reduction of shoaling in Southwest Pass, the Waterways Experiment Station has submitted proposal for constructing a model at a cost of about $1,100,000. Data collection, construction and testing will require about four to five years. The proposed model will reproduce a portion of the Gulf of Mexico adjacent to the entrance to Southwest and South Passes, all of Southwest and South Passes, portions of Pass a Loutre and Cubits Gap and the Mississippi River to about mile 14 above the Head of Passes. Linear scale ratios are 1:400 horizontally and 1:100 vertically. The model will be equipped with all necessary appurtenances for reproducing tidal.phenomena, density currents, fresh water inflow, and 403 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 channel shoaling and will be of the fixed-bed type except for a small section at the Head of Passes area which will have a movable bed for special studies of sediment distribution among the major passes. Construction of the model was approved on March 26, 1969. (c) South Pass: A good channel is available throughout the pass except between miles 9.4 and 9.8 BHP where a depth of 29 feet exists. Shoaling will be removed in July 1969. Controlling channel conditions on June 30, 1969, were 31 feet over bar channel at gulf entrance to pass. Minimum width of channel was 150 feet vicinity mile 10.8 below Head of Passes. Dredging will be accomplished by U. S. dredge Langfitt. Annual maintenance is required on the outlets on each side of pass and the parallel stone dike along the west bank. Contractor has yet to remove two sunken barges from west bank, vicinity mile 11 BHP. Total costs of existing project to end of fiscal year were $110,953,469, of which $33,187,008 was for new work and $77,766,461 was for maintenance. 20. MISSISSIPPI RIVER-GULF OUTLET, LA. Location.

In addition, Coast Guard is to provide navigation aids at an estimated cost of $20,000. Existing project was autho- 9zed by River and Harbor Act of 1968 (S. Doc. 97, 0th Cong., 2d sess., contains latest published map.). Local cooperation. Local interests must provide Without cost to the United States, all lands, easements, and rights-of-way required for construction and sub- Sequent maintenance of the project and for aids to navigation upon the request of the Chief of Engineers, including suitable areas determined by the ief of Engineers, to be required in the general pub- 'lanterest for initial and subsequent disposal of spoil, and also retaining dikes for disposal of spoil from maintenance dredging, if required; accomplish with- Out cost to the United States such utility or other reloations or alterations as necessary for project pur- Poses; and hold the United States free from damages due to the construction and subsequent maintenance of the project, including any erosion beyond the rights-of-way furnished. Assurances of local cooperation were requested by letter dated January 10, 1969, of the Board of Commissioners of the Port of New Orleans. Such assurances were executed on February 3, 1969, and accepted on behalf of the United States on February 24, 1969. Terminalfacilities. There are no public wharves located in the area; however, the developer of the area states that the corporation has retained a tract of land at the north end of the Michoud Canal for construction of a public wharf for seagoing and other marine traffic, which would be avilable to industries without frontage on waterways. Several private facilities are located on the canal and others are anticipated in the future. The Gulf Intracoastal Waterway intersects the Mississippi 'River-Gulf Outlet approximately 1.5 miles westward from the Michoud Canal. This outlet provides a direct tidewater route for ocean shipping. Operations and results during fiscal year. Assurances of local cooperation were acquired. Condition at end of fiscal year. No work other than real estate activities has been initiated. Planning for construction of project will be started in fiscal year 1970. 22. MISSISSIPPI RIVER OUTLETS, VICINITY OF VENICE, LA. Location.

RED RIVER WATERWAY, LA., ARK., OKLA., AND TEX. Location. In east central and northwest Louisiana, southwest Arkansas, northeast Texas, and 'southeast Oklahoma along Old and Red Rivers from the Mississippi River to Denison Dam, Texas, and along Twelvemile and Cypress Bayous from Shreveport, Louisiana, to the vicinity of Daingerfield, Texas. Existing project. Three existing projects, Red River Below Denison Dam, Red River Below Fulton, Ark., and Cypress Bayou and Waterway between Jefferson, Tex., and Shreveport, La., were modified to provide bank stabilization and navigation improvements as follows: Bank stabilization and recreational facilities by realining and stabilizing the banks of Red River from the Mississippi River to Denison Dam, Tex.; a 9- by 200-foot slackwater navigation channel from the Mississippi River through Old and Red Rivers to Shreveport, La., and through Twelvemile and Cypress Bayous to vicinity of Daingerfield, Tex.; and construction of 9 navigation locks, 84 feet wide by 600 feet long, and 7 new dams. Two existing dams, Caddo and Ferrells Bridge, will be utilized in the improvement. The authorization provides that, prior to construction of the navigation features in the reach from Shreveport to Daingerfield, the transportation economics be reanalyzed. It also provides for deauthorization of Mooringsport Reservoir. Estimated cost for new work (July 1968) is $572,000,000, Federal, and $61,000,000 non-Federal, including cash contribution of $27,983,000. In addition, Coast Guard is to provide navigation aids at an estimated cost of $1,- 000,000. Existing project was authorized by River and Harbor Act of 1968 (H. Doc. 304, 90th Cong., 2d sess., contains latest published map). Local cooperation. Provide without cost to the United States all lands, easements, and rights-of-way required for construction and subsequent maintenance of the project and for aids to navigation upon the request of the Chief of Engineers, including all additional land required to assure public control of the recreational development; hold the United States free from damages; maintain all project works after completion; provide a proportioriate share of the cost of bridge alterations over existing channels and assume all obligations of owning, maintaining, and operating all railway and highway bridges altered or constructed as part of project; provide without cost to United States such alterations and maintenance as required in pipelines and utility facilities; provide and maintain at local expense adequate public terminal and transfer facilities; obtain without cost to United States any necessary water rights; where the appraised value of the land provided for recreational development amounts to 50 percent of the total first costs of the recreational development, make additional contributions sufficient to bring the non-Fed eral share to at least that level; operate, maintain, a d assure access to recreational development to all 0o equal terms; and for the reach from Index, Ark., t Denison Dam, provide a cash contribution for land enhancement amounting to 21.1 percent of the estl mated Federal cost of construction. Louisiana: Assurances of local cooperation were executed by the. Red River Waterway Commission on February 26, 1969, and accepted April 15, 1969, on behalf of the United States. Oklahoma: By letter dated December 6, 1968, the District Engineer, U. S Army Engineer District, Tulsa, Okla., was notifie that the New Orleans District had initiated action to secure assurances in Louisiana, Texas, and Arkansas' Arkansas: Through contacts with the Governor ard the Attorney General of the State of Arkansas, it was learned that no existing local agency had authority to furnish local cooperation for the project. Latest Information indicates that the Arkansas Soil and Water Conservation Commission will be authorized to execute the assurances of local cooperation. Texas: the meeting in February 1969, representatives of the Texas Water Development Board stated that they would take favorable action on assurances for the navigation channel from Shreveport to Daingerfield and that favorable action might be taken on the bank stabilization from Shreveport to the head of the levee system. However, they felt the Board would not tae action on any assurances from the head of the levee system to Denison Dam because of the large cash conl tribution required. Breakdown of costs for the project by states is now being prepared and will be furnished together with a formal request for assurances to the State of Texas and to the proper agency in the State of Arkansas when authorized. Operations and results during fiscal year. Initiated action to secure assurances of local cooperation. Condition at end of fiscal year. No work other than real estate activities has been initiated. Planning for construction of project will be started when funds be" come available. 408 NEW ORLEANS, LA., DISTRICT 27. REMOVING WATER-HYACINTH (LOUISIANA) Location. Lakes and streams tributary to the gulf Coast. Existing project. Removal of plants from navigable waters 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 construction eration of and op- boats equipped with suitable machinery for bSouochm sr etmo opvraelv; enat nd construction and operation of plants drifting from one stream to another. (See Table 1 I-B for authorizing legislation.) Localcooperation. None required. Operations and results during fiscal year. A well-balanced conbination of mechanical and chemical methods of destruction was undertaken to take maximum advantage of funds available. Work accomplished in main waterways and their principal tributaries over which major portion of navigation moves. Preventive maintenance work carried out in secondary streams and feeder areas whenever practicable. Feeder areas previously freed of hyacinths and placed on a patrol maintenance basis have become infected with alliga- tOrweed which has not proved to be as susceptible to approved chemical treatment as water-hyacinth. A toal of 7,412 acres of vegetation was treated by chemicals and 25 acres of vegetationwas destroyed by machinery in Bayou Black, Lake Cataouatche, and feeder Streams of Lake des Allemands Basin, Lake Dauterive area, Bayou Penchant-Bayou Copasaw area, Gulf Intracoastal Waterway, streams of Maurepas-Pontcharai Basin, Plaquemine Waterway, Caddo Lake, Bayou Lacassine and Bayou Teche. Operations were bbaassiisso nducted in main navigable streams on a recurring No permanent results can be expected until vegetation in secondary streams and feeder areas has been destroyed. boaCt ownidtition at end offiscalyear. From 1900 to 1902 a bat ith suitable machinery for destroying hyacinth by crushing was operated. From that time until 1937 byacinths were destroyed through use of a solution of tioenic and caustic soda which was sprayed on vegeta- 'on, removal by hand crews, and controlled in their ovements by means of booms and barricades. Use O arsenic was discontinued and hand removal sup- Planted by use of mechanical equipment in conjunction with chemical spray (2,4-dichlorophenoxy-acetic acid). Use of booms and barricades has been discontinued. Present methods of control are by means of mechanical rotary saw-type destroyers, and chemical treatment. Excellent results are being obtained on water- hyacinths by these methods. 28. TANGIPAHOA RIVER, LA. Location.

Flood Plain Management Services Unit: Talks were given to officials of Federal, State and local agencies, and to private organizations on flood plain management activities and flood plain management techniques. Numerous responses were made to request for flood plain information data. Literature on the FPMS program was provided to libraries and interested parties. Meetings were held with planners, private individuals, news reporters, city engineers, consultants, land developers, and attorneys to discuss the various aspects of the FPMS program and flood plain management techniques and to offer assistance in drafting flood plain ordinances. Completed flood plain information reports were provided local officials and reports and pamphlets distributed. A special Michigan State Senate Committee hearing was held 17 December 1967 to discuss the types of new legislation that would be necessary to secure the kind of total flood plain regulation calculated to serve all aspects of the public interest. The District Engineer and FPMS Chief attended this hearing and presented statements on the Corps role in flood plain management. Michigan Senate Bill 960 was subsequently passed and signed by Governor Romney 17 June 1968. The Bill gives the Water Resources Commission power to establish rules for occupation or fill in flood plains. The Bill is now Michigan Act 167, dated 17 June 1968, with immediate effect. Informal meetings were held with members of the Water Resources Commission to discuss, and offer advice and guidance on possible rules and regulations to be established by the Water Resources Commission to implement Act 167. Corps' technical publications were provided the Michigan Water Resources Commission. These publications are to be used as reference sources under rules and regulations to be established by the Commission and were distributed to Michigan County Highway and Drain Commissioners. The Michigan Water Resources Commission established rules and procedures to implement the Subdivision Control Act of 1967 enacted by the Michigan State legislature and in connection with this Act, assistance was provided the State in the technical implementation and review of flood hazard potentials. A special Michigan State Senate Committee hearing was held to discuss the type of new legislation that is necessary to secure the flood plain regulations calculated to serve all aspects of the public interest. Corps representatives attended this hearing and presented a statement on the Corps' role. Total costs were $39,334. b.

The Corps owns a wharf adjacent to Black Rock lock which is private. Eight terminals have railroad connections and six mechanical-handling facilities. Facilities considered adequate for existing commerce. (Port Series No. 41, revised 1960, Corps of Engineers.) Operations and results during fiscal year. Maintenance: U. S. hopper dredge Lyman removed 121,948 cubic yards, bin measure of shoaled material from Black Rock Canal, and Niagara River Channel, for restoration of project depth of 21 feet. Repairs to approximately 100 linear feet of Bird Island pier were made by Government plant and hired labor. Operation and care (Black Rock lock): Lock was in continuous operation 333 days and closed for underwater cleaning and repairs March 5 through April 5, 1969. Ordinary maintenance and repair of structures and grounds were accomplished throughout year by Government plant and hired labor. Total costs of $413,995 were distributed as follows: operation and care: operation of lock, $120,600; ordinary maintenance and repair, $69,800; lock, guards, and maintenance of grounds, $62,900; miscellaneous inspection and condition surveys, $20,900. Maintenance (Repair and dredging) (hired labor): removal of shoals from project channel, $100,100; snagging and clearing in project channels, $36,200; and repairs to Bird Island pier, $3,495. Condition at end of fiscal year: Existing project is about 89 percent complete. Channel from Buffalo Harbor north entrance to opposite Sixth Avenue, 967 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 North Tonawanda, is complete. Different sections of this channel were completed to project depth as follows: Lake Erie section in 1909; Black Rock Canal section in 1915; Niagara River section from lock to deep water pool above Tonawanda, in 1913; and Tonawanda section, including turning basin, 1921. Channel was further widened as follows: Triangular area at Lake Erie entrance to canal was completed in 1922 and transferred from Buffalo Harbor project in 1945; Lake Erie section was widened at bend opposite foot of Georgia Street, Buffalo, in 1924; Black Rock Canal section, just south of International Bridge at Buffalo, in 1928, and opposite foot of Maryland Street, Buffalo, in 1930; and Niagara River section near westerly end of Rattlesnake Island shoal in 1928. Rock shoals extending above a depth of 21.4 feet were removed from Lake Erie entrance to canal and in canal south of Ferry Street Bridge, in 1937. Rock shoals extending above a depth of 22 feet were removed from Lake Erie entrance to canal, in Black Rock Canal, and in Niagara River portion of canal in 1948- 49. Widening Lake Erie entrance to canal was completed in 1958. Tonawanda Creek Channel was completed in 1902. Tonawanda Inner Harbor Channel was completed in 1904. Enlargement of Tonawanda turning basin and extension of Bird Island pier were completed in 1936. Lock, including wing walls and retaining walls above lock, was completed in 1914, and 100-foot east wing wall extension in 1927. Guide pier connecting with west lower wing wall was completed in 1916, except for 200-foot northerly extension and construction of concrete platform in the angle. Upstream 300 linear feet of lower west guide pier were repaired 1951-59. Lock-operating houses were completed in 1924. Work remaining to complete project is improvement and extension of guide pier as authorized by 1935 River and Harbor Act, which is considered inactive, and deepening lower 1,500 feet of Tonawanda Inner Harbor as authorized by 1954 River and Harbor Act, which is to be restudied. All structures are in poor condition. Bird Island pier is badly deteriorated and requires considerable annual maintenance. Several sections of pier fail yearly, requiring removal of stone and debris from channel and repair of structure. Operating equipment and controls for Black Rock lock are antiquated, inefficient, and require substantial repairs periodically. East channel face of lock wall was repaired in 1953, and west channel face in 1954. Upper wing wall of lock has shifted laterally about 2 feet at maximum point, and concrete superstructure on lower guide pier is badly cracked, indicating a possible failure of the timber crib. Controlling depths at low-water datum are: Black Rock Channel 21 feet, 20 feet in Niagara River section of channel and in Tonawanda turning basin, Tonawanda Inner Harbor 14 feet, and Tonawanda Creek Channel 12 feet. Costs of existing project were $10,457,093 (including $1,760,000 emergency relief funds and $6,000 expended for deferred portion of project) for new work; $3,673,253 for maintenance $6,578,230 for operating and care; a total of $20,708,576.

Region in which operations are conducted lies within States of Vermont, New York, Pennsylvania, Ohio, Michigan, Indiana, Illinois, Wisconsin, and Minnesota. For additional details see Annual Report for 1962. Previous projects. In the region described, previous projects of Lake Survey. have specified provision of complete navigation charts designed to suit needs of existing use of waters. These projects, in addition to hydrographic and topographic surveys, contemplated establishment of requisite horizontal and vertical control where not already in existence, and measurement and analysis of other factors pertaining to navigation. A comprehensive statement concerning prior projects on the Great Lakes, and formulation of 'a general project covering to completion the operations of the Survey' appeared in Annual Report for 1907, pages 844 to 850. Responsibilities under prior projects in Great Lakes portion of the region covered, apart from charting and navigational aspects, consisted of those pertaining to lake levels, hydrology, and hydraulics of connecting and outflow rivers. The 1907 Annual Report, referred to above in connection with charting and navigational portions of the project, also discussed prior and existing responsibilities in these respects. A board appointed by the Division Engineer, Great Lakes Division, to study and clarify U. S. Lake Survey activities in this second category formulated a report which included definite recommendations. The board report was presented to the Chief of Engineers and approved January 21, 1935, as basic description of such responsibilities. Existing project. Portion of existing project concerned with charting provides for general maintenance of chart coverage. Various classes of charts are issued consisting essentially of general charts employing small scales; coastal, river, and sectional charts employing medium scales; harbor and confined locality charts employing large scales; and special charts such as those for recreational use employing scales suitable for purposes intended. Number of charts and individual chart scales and coverages are not fixed, project being made purposely flexible to permit alterations to keep abreast of changing needs. Essential to charting, and pertinent to lake levels and hydraulics as well, is the portion of project relating to maintenance of horizontal and vertical control coverage. Original control was established under early projects in connection with initial surveys by U. S. Lake Survey on the Great Lakes and by other Government agencies in the other areas of the district. Original control has been preserved wherever possible; where destroyed, it has been replaced as needed; and where necessary, it has been augmented by additional control for use in connection with later surveys and other Corps work. *All cost and financial statements for projects are listed at the end of this chapter. All other tables are referenced in text and also appear at the end of this chapter. 999 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Project includes publications with information for benefit of navigation in addition to that provided by charts. These consist of such publications as the Great Lakes Pilot and supplements thereto and various lake and river level bulletins. The Pilot, issued annually, supplies full descriptions of physical conditions of waters charted and particulars of constantly changing conditions not adapted to adequate or prompt representation on charts. The supplements, issued monthly during the Great Lakes navigation season, provide corrections and additions to the Pilot. Lake and river level bulletins permit maximum utilization of navigational depths in Federal projects and elsewhere. Since 1859, lake level gages installed and operated by U. S. Lake Survey have provided a continuous record of water levels of the Great Lakes and their connecting rivers. Present project provides for continued operation of a comprehensive gage network. In the fields of applied hydraulics and hydrology, present project provides for continuing studies of all aspects thereof required for discharge of Corps of Engineers responsibilities on the Great Lakes. In addition to the foregoing, the Lake Survey Great Lakes Research Center makes scientific investigations of all aspects of fresh-water oceanography relating to development and utilization of water resources of the Great Lakes system, in conjunction with which field surveys and observations are accomplished, data collected and analyzed and reports published. For additional details of existing project, see Annual Report for 1962. Regulation Representatives. Each Thursday the outflow to be released from Lake Ontario was coordinated for the ensuing week with the Canadian Regulation Representative, and the Power Authority of the State of New York was informed of the quantity. Regulation Plan 1958-D, which was developed as a cooperative project by the Canadian and U. S. Regulation Representatives, was used for the determination of the outflow. Collaboration with Canada in the collection of Lake Ontario and St. Lawrence River data needed for regulation was continued. The District Engineer or a member of his staff attended two meetings of the Board's Operations Advisory Group. Supply forecasts and reports for the Board's information concerning the effects of certain probable supply sequences on the levels of Lake Ontario were made monthly. Operation of Iroquois Dam was requested and authorized on six occasions during the fiscal year. St. Lawrence Committee on River Gaging. Field inspection of the St. Lawrence River water-level gages used by the St. Lawrence River Board of Control was made jointly with the Hydro-Electric Power Commission of Ontario, and monthly random checks were made of the power entities water-level record reductions. Field inspection was made in conjunction with the Inland Waters Branch, Department of Energy; Mines and Resources, Canada, of the procedures for determination of flow through the structures of Lake St. Lawrence, and random check of the flow through the several structures was made for one day each month. The 28th and 29th progress reports of the Committee were prepared and presented to the Board of Control. International Great Lakes Levels Board and Working Committee. The District Engineer or members of his staff attended two meetings of the Board, four meetings of the Working Committee and one meeting of the Subcommittee Chairmen. The District Engineer and/or members of his staff attended four meetings of the Regulation Subcommittee during the year. In addition, close liaison between personnel engaged in the studies for the Working Committee and the Board was maintained through frequent telephone discussions and exchanges of study material. The Regulation Subcommittee during the reporting period forwarded to the Working Committee a report on the basic data being employed in the study, a report on the St. Clair-Detroit River flows and a report on consumptive use of water within the basin. Currently under study are regulation plans for all of the lakes and for various combinations of the lakes. In conjunction with these studies, work has continued on preparation of reports on the hydraulics and hydrology of the system. A member of the staff attended nine meetings of the Regulatory Works Subcommittee Work accomplished by this Subcommittee consisted of review of studies undertaken, a field project to determine the practicability of operating the Sault Ste. Marie compensating works during the winter months, development of methodology for evaluating the cost of channels and structures in the St. Clair and Detroit Rivers and the evaluation of costs of channel changes required for a regulation plan covering all of the lakes. In addition, the staff member participated in the Subcommittee's 1968-69 winter gate tests at the compensating works and started work on a report covering these tests. A member of the staff attended 1000 U. S. LAKE SURVEY various work meetings of the Shore Property Subcommittee which is engaged in evaluating effects of regulation on shore property interests.

The following paragraph contains a narrative summary of Lake Survey activities on the Great Lakes in the fields of hydraulics and hydrology, hydrographic surveys, chart printing, research and related phases of this District's mission. ENGINEERING Hydraulics & Hydrology The following reports on the results of discharge measurements were completed: 1966 Detroit River, Fort Wayne Section and 1966 St. Clair River, Bay Point Section. Reports were started on the results of the following discharge measurements: 1967 Niagara River, Tonawanda Channel; 1967 Niagara River Maid-of-the-Mist-Pool; 1968 Detroit River, Ft. Wayne Section; 1968 St. Clair River, Bay Point Section; and 1969 cooperative measurements with Water Survey of Canada of flow through St. Marys River compensating works. Application of ADP for reducing discharge measurements, as developed by the Lake Survey, was used for providing Water Survey of Canada the results of its portion of the cooperative discharge measurements in the Niagara River during 1967, Stella-Niagara Section in the lower Niagara 1001 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 River and the Chippawa Channel Section in the upper river. Similar computation was provided for the Water Survey of Canada's 1968 measurements of the upper Niagara River at Austin Street Section. During May 1969 cooperative measurements of the flow through the St. Marys River compensating works were conducted in conjunction with the Water Survey of Canada. One set of measurements was obtained above the structure simultaneously with another set measuring flows through. the gates of the works. Channel design for the St..Clair and Detroit Rivers was completed for two trail regulation plans for the Great Lakes Levels Board studies on Lake regulation. The monthly flows of record in the St. Clair and Detroit Rivers were determined for the Regulation Subcommittee of the afore-mentioned Board. Through its membership on the Regulatory Works Subcommittee, the Lake Survey participated in the Subcommittee's 1968-1969 winter test program for increasing the flow in the St. Marys River under ice conditions. A report on the Lake Superior Outflows was completed for the Coordinating Committee on Great Lakes Basic Hydraulic and Hydrologic Data by the River Flow Subcommittee. For the International Niagara Working Committee, a comprehensive hydraulic report was prepared on 'Effects of Power Operation on the Niagara River and Lake Erie'. This report contains the results of the 1967-68 discharge measurements and the design and operation of a mathematical model of the upper Niagara River. Studies were started to define the vertical velocity distribution using the data obtained in 1968 from the eleven simultaneous meter measurements on the St. Clair and Detroit Rivers. During the year, effects of the following proposed channel changes were determined for Detroit and Buffalo Districts: fill in Maumee Bay at Toledo; fill to proposed harbor lines in the Saginaw River and fill and excavation in St. Lawrence River at Ogdensburg, N. Y. Data gathered during FY 1968 from a submerged, continuously-recording current meter were reduced and analysis of results was started to explore the possibility of obtaining 'continuous measurements of discharge. Fluorescent dye experiments for measurement of discharge were conducted and a report is being prepared for publication. Fifty studies were completed relative to the afore-mentioned projects plus other reports. (Note that the foregoing operations do not include certain operations conducted specifically for international boards and committees. These operations are described later in a separate section herein. Note, however, that some of the foregoing operations are pertinent to the work of the international groups as well as to the basic Lake Survey mission.) ENGINEERING Hydrographic Surveys. Inshore hydrographic and sweeping surveys were made in Lake Michigan off the Chicago Lake Front, offPentwater, Michigan, and in Manitou Passage. Horizontal control was established where needed in these areas. Revisory surveys on Lake Michigan begun in FY 68 were completed, and similar surveys on Lake Huron and Superior and along the St. Marys River were started. Surveys required for the maintenance of vertical control at harbors and gage sites along these waters were accomplished. Thirty-three special waterlevel gages, established earlier in selected harbors on Lakes Michigan, Huron, and Superior, were continued in operation through September 1968. These gages were required to obtain data for verifying or establishing vertical control. Sixty-six similar gages were installed at harbors on Lakes Michigan, Huron, Superior, Erie and Ontario in May 1969. Field work for the re-evaluation of International Great Lakes Datum (1955) was continued with instrumental level lines of high-order accuracy being completed along portions of the south shore of Lake Ontario, the St. Lawrence River and the Lower Detroit River. Gravity measurements were taken over bench marks in the reach between Olcott and Massena, New York. ENGINEERING Chart Printing. Ninety Lake Survey Charts were printed; consisting of 58 new editions, of which 2 were Recreational Books of Charts, 2 were folded Small Craft Charts and 1 was the new Mercator Projection Chart of Lake Michigan, and 32 were reprints of current editions for a total of 220,000 copies. In addition, 81,500 copies of the Lake Survey Monthly Bulletin of Lake Levels were printed. Work for other Districts consisted of 36 Status Maps, 207 Project Maps, 12 Flood Plain Maps, 61 miscellaneous maps for a total of 427,876. Changes in critical chart data, including aids to navigation, were made by hand on 105,148 charts to insure accuracy to the date of distribution. This activity totaled 1,088,078 separate operationswhereby certain chart features were deleted and new items added. GREAT LAKES RESEARCH CENTER Water Motion.

On California coast, 65 miles northwest of Los Angeles Harbor and 345 miles south of San Francisco. (See Coast and Geodetic Survey Charts 5007 and 5202.) Existing project. A harbor for light-draft vessels, on coast of southern California about a mile northwest of existing harbor of Port Hueneme, and beach erosion control works. Ventura County, sponsor of project, requested modification of document plan of harbor improvement and submitted a modified plan that was adopted and approved by Chief of Engineers in 1957. The harbor, which provides facilities for berthing and servicing about 640 small craft and commercial fishing boats, includes an entrance channel 20 feet deep, 300 feet wide, and 1,650 feet long protected by two parallel entrance jetties 1,270 and 1,300 feet long; an entrance basin 20 feet deep, 300 to 750 feet wide, and 1,750 feet long; an inner basin 10 feet deep, 900 to 1,400 feet wide, and 1,200 to 2,000 feet long; and a side basin 10 feet deep, 100 to 250 feet wide, and 900 feet long. About 6,238,000 cubic yards of dredged material from entrance channel, interior basins, and sandtrap were deposited in feeder-beach area to restore downcoast shoreline. A 2,300-footlong offshore breakwater was placed to form a sandtrap in conjunction with jetties. About 2,000,000 cubic yards of material are to be dredged each biennium from sandtrap formed by jetties and breakwater. This material will also be deposited along the downcoast shoreline as long as the area remains under Federal ownership and requires beach erosion control. Plane of reference is mean lower low water. Range between mean lower low water and mean higher high water is 5.4 feet. Extreme range is about 8.5 feet. Federal first cost of new work on project as modified was $5,123,- 345 (excluding $1,361,668 Navy funds and cost to Coast Guard for installation of aids to navigation). Existing project was adopted by 1954 River and Harbor Act (H. Doc. 362, 83d Cong., 2d sess.).

Deepening tidal canal from 18 to 25 feet and Federal participation in reconstruction of Fruitvale Avenue Highway Bridge to be restudied and are excluded from foregoing cost estimate. Estimated cost of tidal canal deepening (1954) is $489,069. Estimated cost of Federal participation in reconstruction of Fruitvale Avenue Highway Bridge (1960) is $1,750,000. (See table 34-B for authorizing legislation.) Local cooperation. Act of January 21, 1927, requires that future maintenance by the United States of north channel in Brooklyn Basin be contingent upon removal by local interests of all sewers emptying therein, or, in lieu of such removal, upon contribution of one-half the cost of maintenance. This requirement 1049 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 has not been fulfilled. In compliance with a 1910 license issued by Secretary of War pursuant to provisions of act of June 25, 1910, local interests replaced bridges at Park Street and High Street and are operating and maintaining them. They operated and maintained a combined highway and railroad bridge at Fruitvale Avenue until 1942 when California Court of Appeals ruled that it was illegal for County of Alameda to use appropriated funds for sole benefit of a private corporation. Southern Pacific Railroad Co. operated trains over combined bridge until June 1951 when a separate railroad bridge, constructed for its use by the Federal Government, was placed in operation. (Railroad and highway bridges at Fruitvale Ave. are maintained and operated by the United States.) All other requirements have been fully complied with. Only fragmentary records are available of costs to local interests in meeting requirements of local cooperation. Recorded expenditures are in excess of $11 million. Act of October 23, 1962, requires that local interests provide lands and rights-of-way for construction and maintenance; hold the United States free from damages to wharves, piers, tubes, and other marine and submarine structures due to initial dredging and future maintenance; alter sewer, water supply, drainage, and other utility facilities; provide and maintain adequate public terminal and transfer facilities, open to all equally; deepen and maintain slips and berths; and if required furnish spoil-disposal areas including necessary dikes, bulkheads and embankments for initial dredging and future maintenance. State of California, on September 12, 1961, furnished assurances that it will hold the United States free from liability for damages to Posey and Webster Street Tubes due to initial dredging and subsequent maintenance. Required assurances of cooperation for all other items provided by Port of Oakland and city of Alameda. Port of Oakland is negotiating for spoil-disposal areas with various Federal and State agencies concerned with, or having jurisdiction over, filling of bay tidelands. Terminal facilities. See Port Series No. 31, 'The Ports of Oakland, Alameda, and Richmond, and Ports on San Pablo Bay, Carquinez Strait, and Mare Island Strait,' revised 1962. Facilities will be adequate for existing commerce upon completion of 7th Street Terminal under construction to provide an additional nine deep-water berths. Operations and results during fiscal year. New work: Advance engineering and design for deepening inner harbor channels continued by hired labor. Maintenance: Engineering and design, including dredging surveys, and U.

All other tables are referenced in text and also appear at the end of this chapter. 1075 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 downstream from Mossdale State Highway Bridge, or 13.5 miles above mouth of Stockton Channel, and flows westerly and northerly 32 miles to its lower confluence with main river 23 miles above its mouth in Suisun Bay. Existing project. For description of improvement and authorizing act, see Annual Report for 1967. Total first cost for completed portion $26,785 ($23,185 was Federal and $3,600 non-Federal for lands, damages, and public landings). Uncompleted portion of project is considered inactive and excluded from foregoing cost estimate. Estimated cost of this portion $63,815, of which $62,815 (July 1954) was Federal and $1,000 non-Federal (1939) for lands, damages, and public landings. Local cooperation. Fully complied with for completed portion. Terminal facilities. Holly Sugar Co. refinery and terminal near Tracy has a large wharf and an unloading basin with three mechanical unloading and conveying units connecting with a warehouse; there is also a passing basin one-half mile downstream. There are about 100 private bank landings along project channels; some have sheds for storage. These are all privately owned and operated. Existing commerce does not indicate a need for provision of public landings. Operations and results during fiscal year. Maintenance: Condition studies and miscellaneous inspections and reports by hired labor. Dredging shoals in Doughty Cut to Sugar Canal by contract suction dredge, $48,978. Condition at end of fiscal year. New work was accomplished in fiscal year 1939 in Old River channel from its head in San Joaquin River to Grant Line Canal and in channels of Grant Line Canal, Crocker Cut, and Doughty Cut. Existing commerce does not indicate a need for completion of remaining channel construction. Channel is navigable all year. The two heads of navigation are at head of Old River in San Joaquin River, and at Holly Sugar Factory wharf, 2 miles north of Tracy. Controlling depths: From mouth of river to Orwood, 11 miles, 10 feet; thence to lower end of Grant Line Canal, 10 miles, 10 feet; thence; (a) to Holly Sugar Factory near Tracy, 7 feet (low-water season), or (b) to head of Old River in San Joaquin River, 5 feet (low-water season). All depths refer to mean lower low water. 2. SACRAMENTO RIVER, CALIF. Location. Rises in Trinity Mountains in north-central California, flows generally southerly about 374 miles and empties into Suisun Bay, an arm of San Francisco Bay, at Collinsville, Calif. (See Geological Survey topographic map of Sacramento Valley, Calif.) Previous projects. For details see page 1985 of Annual Report for 1915, and page 1708, Annual Report for 1938. Existing project. Provides for construction of Sacramento River Deep Water Ship Channel from deep water in Suisun Bay to Washington Lake, 1.5 miles west of Sacramento River at city of Sacramento, a distance of 43 miles, construction of a harbor and turning basin at Washington Lake, and a connecting canal with navigation lock from harbor to Sacramento River. Project also provides for a shallow-draft channel 10 feet deep at mean lower low water 150 to 200 feet bottom width, from Suisun Bay to Sacramento, Calif., 60 miles; a depth of 6 feet at low water between Sacramento and Colusa, 85 miles; a depth of 5 feet at low water between Colusa and Chico Landing 50 miles; and such depths as practicable between Chico Landing and Red Bluff, 53 miles, a total distance of 248 miles. (See table 35-C on tidal and flood conditions prevailing.) Deep water channel was formed by widening and deepening existing channels for first 18 miles above Suisun Bay.to 6 miles above Rio Vista and dredging a new channel for remaining 25 miles to Washington Lake, to 30 feet deep at mean lower low water with a bottom width of 200 to 300 feet. Triangular harbor and turning basin was formed by deepening and wid" ening Washington Lake to 30 feet deep at mean lower low water, 2,400 by 2,000 by 3,400 feet, with provision for future enlargement. The 1 1/2-mile long canal 13 feet deep and 120 feet wide between harbor and Sacramento River, together with navigation lock provides for transfer of barges between the two different water surface elevations. A 135-foot span single leaf combination highway and railroad bascule bridge crosses the canal at harbor end of navigation lock. (See table 35-D for principal features of lock.) Approved estimates (July 1969) of new work for project (exclusive of terminal facilities for deep water ship channel) are set forth in table 35-E. In order to permit passage of oceangoing vessels, California reconstructed bridge across Sacramento 1076 SACRAMENTO, CALIF., DISTRICT River at Rio Vista at estimated cost of $3,200,000. Salinity control (reclamation of tidal areas) is considered inactive and excluded from foregoing cost estimate. Estimated Federal cost of this project unit (July 1960) is $2 million plus Government costs, for construction.( See table 35-B for authorizing legislation.) Local cooperation. Fully complied with for deep Water ship channel project. None required on shallow- draft feature. Terminal facilities. Piers, wharves, and docks at Port of Sacramento for shallow-draft navigation are Open-pile structures with timber decks, some of which are designed to meet extreme high waters at flood stages. All main wharves at Sacramento have rail connections. Three of above facilities are owned by city of Sacramento and remainder by private are interests; all privately operated. For full description see 'Port and Terminal Facilities at the Ports of Stockton and Sacramento, Calif., 1962.' Deep water terminal facilities comprise wharves and piers, administration and torage buildings, and belt railroad facilities. Majority of these facilities are owned and operated by Sacramento- Yolo Port District; remainder are privately Owned and operated. Facilities are considered adequate for existing commerce. Operationsa nd results duringfiscaly ear. New work, Deep Water Ship Channel: Engineering and design in connection with channel were continued. (See table 35-F for major items of work included in maintenance.) Condition at end of fiscal year. Construction of 7-foot shallow-draft channel below Sacramento was initiated in September 1899 and completed in 1904. Modified 10-foot shallow-draft channel up to Sacramento was initiated in fiscal year 1928 and completed in 1931. Shallow-draft channel above Sacramento began in April 1946 and new work is about 49 percent complete. Work remaining to complete shallow-draft Portion of projects is provision of a 5-foot depth between Colusa and Chico Landing (50 miles). Completion of shallow-draft channel is indefinite. Construction of 30-foot deep water ship channel was initiated in July 1949; improvement dredging by continuing Contracts resulted in provision of an operational facility for oceangoing vessels during June 1963. Bascule bridge was completed in April 1960, barge lock in August 1961, and barge canal in November 1961. Entire deep water ship channel is about 96 percent complete. Controlling low-water-season depths for shallowdraft channel were: From mouth of Cache Slough to Sacramento, 10 feet; thence to Colusa, 6 feet; thence to Sidds Landing, 3 feet; and thence to Red Bluff, head of navigation, 1.5 feet. Channel is navigable all year; however, there is no regular navigation above Colusa, 145 miles above river mouth. Deep-draft channel will have a controlling depth of 30 feet for deep-draft vessels after annual maintenance dredging. Project will not be completed until certain items deferred due to site conditions or uncertainty as to requirements have been completed. Items comprise: (a) Final shaping ship channel levees to provide design height, without which levee fills already placed could be washed out by floodflows in Yolo Bypass; foundation conditions were such that shaping could only be done in stages; (b) patrol roads on ship channel levees to facilitate maintenance inspection of levees; and (c) bank protection where required to control or prevent erosion of channel banks; specific requirements cannot be entirely determined until project operation discloses where erosion is to be expected. 3.

Location. On Chowchilla River about 36 miles 1080 SACRAMENTO, CALIF., DISTRICT above its mouth and about 16 miles northeast of city of Chowchilla, Calif. (See Geological Survey quadrangles for area.) Existingproject. Provides for construction of a 205- foot high rockfill dam to create a reservoir with gross storage capacity of 150,000 acre-feet for flood control, irrigation, recreation, and fish and wildlife. In conjunction with dam, project plan provides for about 5 miles of downstream levee and channel construction on Ash Slough to accommodate a project design flow of 5,000 cubic feet per second within slough. Operation and maintenance of dam and reservoir will be re- Sponsibility of the Federal Government. Approved cost estimate (July 1969) for existing project is $18,- 250,000, of which $18,000,000 is Federal cost, including $1,070,000 for basic recreation facilities, and $250,000 non-Federal costs for lands and damages, including relocations for downstream levee and channel improvements. Local interests have contracted With Bureau of Reclamation for irrigation service. For future non-Federal reimbursement, see Local Cooperation paragraph. Local interests have also, over a period of years, expended about $500,000 for construction of low levees and clearing downstream channels to provide some local flood protection in project area. This work is inadequate during major floods. Existing project was adopted by 1962 Flood Control Act (S. Doc. 98, 87th Congress, 2d sess., contains latest published map). Local cooperation. California officially adopted pro- Ject by chapter 1203 of statutes of 1963, and by chapter 1438 of those statutes authorized State Reclamation Board to furnish assurances that requirements for supplemental channel improvements will be met. With respect to the dam and reservoir, local interests must reimburse the Federal Government the portion of first cost and annual operation and maintenance costs allocated to irrigation functions of the project. These costs are estimated at 44.3 percent of the jointuse first cost and 41.9 percent of joint-use annual costs. Project authorization provides for project to be financially integrated into the Central Valley project of the Bureau of Reclamation. Irrigation repayment contracts were executed with the Chowchilla and La Branza Water Districts by the Bureau of Reclamation May 28, 1968. Local interests sponsoring any permanent pool in the reservoir for fish and wildlife or recreation must settle all claims for water rights pertaining to establishment and use of a permanent pool for these purposes. With respect to supplemental channel improvement work, section 3, Flood Control Act of June 22, 1936, applies. Local interests must also preserve, or restore and thereafter maintain, the other channels of Chowchilla River and Ash and Berenda Sloughs, from Buchanan Dam downstream to Chowchilla Canal, at capacities existing in 1960. Formal assurances for supplemental channel improvements have not been requested. Operations and results during fiscal year. New work: Plans and specifications for dam and appurtenances were essentially completed. Test quarry and test fill were completed at contract cost of $29,799. Acquisition of real estate was continued. Had the project been in operation, damages preliminarily estimated at $1,- 300,000 from the January-February 1969 floods would have been prevented. Condition at end of fiscal year. Preconstruction planning is complete. 10. CALAVERAS RIVER AND LITTLEJOHN CREEK AND TRIBUTARIES, INCLUDING NEW HOGAN AND FARMINGTON RESERVOIR, CALIF. Location.

(See Geological Survey quadrangles for area.) Existingproject. Provides for construction of a 163- foot high earthfill dam to create a reservoir with gross storage capacity of 90,000 acre-feet for flood control, irrigation, recreation and other purposes. In conjunction with the dam, the project plan provides for about 7 miles of downstream levee and channel improvements on Fresno River from Fresno River bypass to 1083 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Chowchilla Canal to accommodate project design flow of 5,000 cubic feet per second. Operation and maintenance of dam and reservoir would be responsibility of Federal Government. Approved estimated (July 1969) cost for existing project is $21,000,000, of which $20,700,000 is Federal cost, including $1,280,- 000 for basic recreation facilities, and $300,000 non- Federal cost for lands and damages including relocations for downstream levee and channel improvements. Local interests have contracted with Bureau of Reclamation for irrigation service. For future non- Federal reimbursement, see Local Cooperation paragraph. Local interests have also, over a period of years, expended about $300,000 for construction of low levees and clearing downstream channels to provide some local flood protection in the project area. This work is inadequate during major floods. Existing project was adopted by 1962 Flood Control Act (S. Doc. 37, 87th Cong., 1st sess., contains latest published map). Local cooperation. California officially adopted project by chapter 1202 of statutes of 1963, and by chapter 1438 of those statutes authorized State Reclamation Board to furnish assurances that requirements for supplemental channel improvements will be met. With respect to the dam and reservoir, local interests must reimburse the Federal Government the portion of first cost and annual operation and maintenance costs allocated to irrigation function of project. These costs are estimated at 21.7 percent of the joint-use first cost and 15.9 percent of joint-use annual costs. Project authorization provides for project to be financially integrated into the Central Valley project of the Bureau of Reclamation. Irrigation repayment contract was executed by the Bureau with the Merced Irrigation District August 5, 1968. Local interests sponsoring any permanent pool in the reservoir for fish and wildlife or recreation must settle all claims for water rights pertaining to establishment and use of a permanent pool for these purposes. With respect to supplemental channel improvement work, section 3, Flood Control Act of June 22, 1936, applies; relocations include relocation of highway facilities and utilities. Local interests must also preserve, or restore and thereafter maintain, the Fresno River channel from Hidden Reservoir downstream to the authorized channel work at the capacities prevailing in 1959. Formal assurances for supplemental channel improvements have not been requested. Operationsa nd results duringfiscaly ear. New work: Engineering continued. Acquisition of real estate was initiated. Had the project been in operation, damages from the January-February 1969 floods preliminarily estimated at $1,300,000 would have been prevented. Condition at end of fiscal year. Preconstruction planning is complete. 13. ISABELLA RESERVOIR, KERN RIVER, CALIF. Location.

Estimated Federal cost (July 1969) for new work is $22,036,000, including $11,600 for recreation facilities. For future non-Federal reimbursement see Local Cooperation and Licenses paragraphs. Estimated Federal cost (July 1969) of recreation facilities for Isabella Reservoir, to be funded from Code 710 appropriations is $2,555,000, exclusive of recreation facilities previously provided by regular funds above. Operation and maintenance of dam and reservoir is Federal responsibility. Local cooperation. California officially adopted project by chapter 15 14 of statutes of 1945, State of Cali - fornia. Local interests, represented by North Kern, Buena Vista, and Tulare Lake Basin Water Storage Districts and La Hacienda Water District, were required to reimburse the Federal Government the portion of first cost and annual operation and maintenance costs allocated to irrigation functions of project. These costs based on a cost allocation study con' pleted in December 1955, are $4,573,000 of first cost and 21.7 percent of annual operation and maintenance costs. For the years 1956 through 1964, an interim contract between Bureau of Reclamation and local water users provided for storage and payment of irrigation water. Under provisions of this interim contract, local interests paid $1,936,229 through December 31, 1964. A long-term contract between the Bureau and local water users was executed October 23, 1964. Balance due on allocated first cost of $4,- 573,000 was paid by the water users on March 31, 1965. Kern County assumed administration of recreation and development and maintenance of public use areas at project in accordance with a 25-year license 1084 SACRAMENTO, CALIF., DISTRICT February 13, 1955. The agreement with Kern County provides for joint operation and development by the Corps and Kern County. Permits have been granted to concessionaires by the county to provide certain services not rendered by the county. Total cost of present recreation facilities developed by the county and its concessionaires is about $1 million; $235,000 of this was a grant from the California Wildlife Conservation Board and about $340,000 is investment by concessionaires. This investment provided partial development of 21 recreation sites around the reservoir. Licenses. In accordance with Federal Power Commission Docket No. E-6578, issued April 1, 1963, payment of $377,426 was made to the Federal Government by Pacific Gas and Electric Co. ($108,352) and Southern California Edison Co. ($269,074) for headwater benefits to downstream existing plants from Isabella Dam to cover benefits from April 15, 1954, to December 31, 1962. Subsequent to 1962, the power companies have in the aggregate made annual payments of $44,650 for headwater benefits. That amount will be paid each year until changes in operation, development, or costs indicate some modification to be advisable. Cumulative use charges collected by the Federal Power Commission and returned to the U.S. Treasury through period ending June 30, 1968, amounted to $645,326. Operations and results duringfiscal year. New work, regular funds: Minor engineering continued. Code 710 funds: Engineering studies and plans and specifications for recreation facilities were continued. Restrooms and sanitary facilities at Boulder Gulch, Hungry Gulch, and Live Oak campgrounds were completed by contract, $170,859. Provided additional campground facilities at Main Dam campground by contract and hired labor, $25,108. Maintenance: Maintenance and operation activities continued with condition and operation studies at a cost of $52,549 and major maintenance costs as follows: dam and reservoir $58,760; service facilities $27,804; and recreation facilities $214,922. Structures were maintained in good condition. Runoff of Kern River above Isabella Reservoir for the year was the highest ever recorded. Snowmelt season runoff approaching 402 percent of normal resulted in a maximum storage of 569,663 acre-feet on June 30, 1969, only 367 acrefeet below the spillway crest. After 16 years of operation at Isabella Dam, the storage is nearing the gross pool level for the first time. Maximum bihourly inflow to Isabella Reservoir was 32,400 cubic feet per second on January 25, 1969, and maximum outflow of 7,023 cubic feet per second occurred June 5, 1969. Release of water for irrigation and spreading uses totaled 1,090,000 acre-feet. Water released for flood control during the snowmelt flood period amounted to 446,- 000 acre-feet, of which 31,000 acre-feet reached the Buena Vista Lakebed area and 216,000 acre-feet reached Tulare Lakebed area. Isabella Reservoir completely contained the January-February 1969 floods which, if uncontrolled, would have inundated parts of Bakersfield and adjacent suburban area and also would have flooded areas of agricultural cropland. Project prevented an estimated $27,600,000 in damages from the January-February 1969 rainfloods and the May-June 1969 snowmelt runoff. Condition at end of fiscal year. Construction began in March 1948 and was completed in June 1968. Main dam, Borel Canal outlet works and appurtenances, and auxiliary dam were completed in April 1953. Storage impoundment began December 1952. Project is operating to provide flood protection and irrigation benefits for which it was designed. Additional recreation facilities are to be provided by Code 710 funds. 14. KAWEAH AND TULE TERMINUS AND VOIRS, CALIF. RIVERS, INCLUDING SUCCESS RESERLocation. Terminus Reservoir is on Kaweah River about 20 miles east of Visalia, Calif. Success Reservoir is on Tule River about 5 miles east of Porterville, Calif. (See Geological Survey quadrangles of area.)

Terminus Reservoir: A rolled earthfill and rock shell main dam structure 250 feet high and 2,375 feet long, and auxiliary earthfill dam 130 feet high and 870 feet long, and an ungated spillway in left abutment of dam. Reservoir has a gross storage capacity of 150,000 acre-feet. Spreading facilities of capacity contemplated in authorizing document, comprising a complex system of channels, basins, and other irrigation facilities, have been constructed by local interests since preparation of survey report. Such spreading development is fully adequate for project purposes. Success Reservoir: A rolled earthfill main dam structure 142 feet high and 3,490 feet long, an auxiliary rolled-earthfill dam or dike 40 feet high and 7,650 feet long across Frazier Valley about 3 1/2 miles northwesterly from main dam, and 1085 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 an ungated spillway. Reservoir has a gross storage capacity of 85,000 acre-feet. Estimated Federal cost (July 1969) of new work for Terminus Reservoir is $19,298,000, including $207,000 for basic recreation facilities. In addition, spreading works contemplated for Terminus Reservoir were constructed by local interests at an estimated (July 1957) cost of about $750,- 000. Estimated Federal cost (July 1969) of new work for Success Reservoir is $14,257,000, including $193,- 000 for basic recreation facilities. For future non- Federal reimbursements, see Local Cooperation paragraph. Federal construction of spreading facilities for Terminus Reservoir is considered inactive and excluded from foregoing Federal cost estimate. Estimated cost of this project unit (July 1957) is $750,000 for construction. Estimated (July 1969) Federal cost of recreation facilities, to be funded from Code 710 appropriations is $793,000 for Terminus Reservoir and $740,000 for Success Reservoir. Operation and maintenance of reservoirs is Federal responsibility. Flood Control Act of 1944 authorized existing project and $4,600,000 for initiation and partial accomplishment of construction of Success and Terminus Reservoirs. Additional monetary authorization for completion of this comprehensive plan was provided by Public Law 85-500 (H. Flood Control Committee Doc. 1, 78th Cong., 2d sess., & H. Doc. 559, 78th Cong., 2d sess., contains latest published map). Lake formed by Terminus Dam was designated 'Lake Kaweah' by Public Law 87-568. Local cooperation. California officially adopted projects by chapter 1514 of statutes of 1945, State of California. Local interests for Terminus Reservoir are represented by Kaweah Delta Water Conservation District. Local interests for Success Reservoir are considered to be represented by the Vandalia, Porterville, and Lower Tule River Irrigation Districts, the Tulare Lake Basin Water Storage District, and Pioneer Water Co., which represent over 90 percent of irrigated land and water-right holders along Tule River below damsite. Local interests must reimburse the Federal Government the portion of first cost and annual operation and maintenance costs allocated to irrigation functions of projects. These costs are estimated at 14.1 percent of first and annual costs for Terminus Reservoir and 9.5 percent of first and annual costs for Success Reservoir. Local interests for Terminus Reservoir also stated they will continue to operate and maintain spreading works and downstream channel systems to provide required capacity for disposal of floodwaters. Local interests for Success Reservoir also stated they will continue to maintain downstream channel systems to provide required capacity for disposal of flood waters. Repayment contracts between Bureau of Reclamation and local water users for irrigation supply from Terminus and Success Reservoirs were executed January 11, 1965, and April 30, 1965, respectively. Reservoirs are being operated for irrigation storage as well as flood control and incidental recreation use. Tulare County acquired water for recreation pools at the projects. Local interests paid the follow" ing total amounts for irrigation services through June 30, 1968: Terminus Reservoir, $441,705 and Success Reservoir, $188,171. Tulare County was granted a 25-year license for planning, development, and management of public recreation areas at Success Reservoir July 10, 1960, and at Terminus Reservoir, June 5, 1961. Basic public-use facilities constructed by Corps at Success Reservoir were transferred to jurisdiction of Tulare County on January 18, 1962; facilities at Terminus were transferred June 20, 1962. In March 1967, an amendment to the license agreements was approved by the Assistant Secretary of the Army. Under these amended licenses, Tulare County retained administration of only specified land areas and operation and maintenance of recreation facilities in these areas. In addition, they continued their program of water safety, boat inspection, and law enforcement at both Terminus and Success Reservoirs. The Corps took over the administration of the remainder of the project land areas and the operation and maintenance of recreation facilities in these areas. California Department of Fish and Game expended funds to improve fishery resources of Terminus Reservoir. Tulare County, by expenditure of county funds and by a lease to a concessionaire, has partially developed five recreation sites around the reservoir. Estimated cost of facilities installed by the county is $53,000. California Department of Fish and Game expended funds to improve fishery resources of Success Reservoir, and, in conjunction with Tulare Sportsman's Council, developed a habitat for upland game birds. County of Tulare, by expenditure of county funds, by leases to concessionaires, and with assistance from California Department of Fish and Game and Tulare Sportman'S Council, has partially developed six areas, some of which were provided with temporary facilities. Estimated cost of these facilities is $307,000. Operations and results during fiscal year. New work: 1086 SACRAMENTO, CALIF., DISTRICT Terminus Reservoir, regular funds: None. Code 710 funds: Continuation of engineering. Success Reservoir, regular funds: Minor hired labor. Code 710 funds: Continuation of engineering. Provided additional sewerage facilities at Tule Campground by contract, $31,611. Maintenance: Terminus Reservoir: Maintenance and operation activities continued with condition and operation studies at a cost of $41,348 and major maintenance costs as follows: dam and reservoir $39,- 070; service facilities $15,741; and recreation facilities $43,130. Structures were maintained in serviceable condition. Runoff of Kaweah River above Terminus Reservoir was much above normal for the year. Rain in late January 1969 resulted in a maximum Storage of 139,900 acre-feet, 10,100 acre-feet below the uncontrolled spillway crest. After subsequent evacuation, until late February 1969, another rainflood resulted in a maximum storage of 117,300 acrefeet. Again after evacuation at maximum channel capacity rates, snowmelt season runoff approaching 306 Percent of normal resulted in maximum storage of 158,800 acre-feet on June 26, 1969, surcharged 4.68 feet above spillway crest by means of a temporary barrier constructed in the spillway notch. Maximum bihourly inflow to Terminus Reservoir on January 25, 1969, was about 35,100 cubic feet per second. Maximum outflow from reservoir occurred on June 7, 1969, and was 5,589 cubic feet per second. Water released for flood control during the three flood periods amounted to 910,300 acre-feet, of which 355,000 acre-feet reached the Tulare Lakebed area. Operation of Terminus Dam and Reservoir prevented flooding in Visalia and other communities in flood plain as Well as adjacent agricultural lands. Project prevented an estimated $10,800,000 in damages from the January- February 1969 rainfloods and May-June 1969 Snowmelt runoff. Success Reservoir: Maintenance and operation activities continued with condition and operation studies at a cost of $36,977 and major maintenance COsts as follows: dam and reservoir $45,597; service facilities $16,382; and recreation facilities $41,917. Structures were maintained in serviceable condition. Runoff of Tule River above Success Reservoir was above normal during the year. Rain occurring late in January and in late February produced a peak storage of 83,800 acre-feet, only 1,600 acre-feet below the uncontrolled spillway crest. Maximum bihourly inflow to Success Reservoir was 22,500 cubic feet per second on January 25, 1969, and maximum outflow of 3,208 cubic feet per second occurred on February 28, 1969. After subsequent evacuation at channel capacity rates, snowmelt season runoff approaching 397 percent of normal resulted in maximum storage of 95,300 acrefeet on June 20, 1969, surcharged 3.92 feet above spillway crest by means of a temporary barrier constructed on the spillway sill. Release of water for irrigation and spreading totaled 40,100 acre-feet. Water released for flood control during the three periods amounted to 368,600 acre-feet, of which 196,000 acre-feet reached the Tulare Lakebed area. Operation of Success Dam and Reservoir prevented flooding in Porterville and suburban areas. Project prevented an estimated $6,600,000 in damages from the January- February 1969 rainfloods and May-June 1969 snowmelt runoff. Condition at end of fiscal year.

LOWER SAN JOAQUIN RIVER AND TRIBUTARIES INCLUDING TUOLUMNE AND STANISLAUS RIVERS, CALIF. Location. (a) New Melones Reservoirs: (See Improvement No. 34). (b) Tuolumne River Basin: Cherry Valley Reservoir-on Cherry Creek in upper Tuolumne River watershed, about 12 miles above junction with Tuolumne River, in northwest corner of Yosemite National Park, Calif. New Don Pedro Reservoir- on Tuolumne River, a tributary of San Joaquin River, in Tuolumne County, Calif., about 32 miles east of city of Modesto. (c) Lower San Joaquin River and tributaries: On lower reaches of San Joaquin River and of Stanislaus and Tuolumne Rivers. (See Geological Survey quadrangles of area.) Existing project. Tuolumne River Basin: A Federal contribution for flood protection to be afforded by local interests' construction and operation of Cherry Valley and New Don Pedro Reservoirs for municipal water supply, power generation, irrigation, and flood control. Ultimately the flood protection will be derived from operation for flood control of at least 340,- 000 acre-feet of storage in New Don Pedro Reservoir. First phase of development by local interests was construction, for municipal water supply, power generation, and other purposes, of Cherry Valley Reservoir in upper Tuolumne River watershed, completed in December 1955 for interim flood control storage. Second phase of development will be construction of New Don Pedro Dam on Tuolumne River. Improvement will comprise a rock and earthfill dam, 565 feet high, to create a reservoir capacity of 2,030,000 acrefeet for purpose of municipal water supply, power generation, irrigation, and flood control. Approved cost estimate (July 1969) is $71,236,000 comprised of $56,200,000 non-Federal cost; $14,464,000 Federal contribution, including payments totaling $9,000,000 made to local interests toward first phase; and $572,- 000 Federal engineering and administrative costs, including $236,000 expended for initial phase. Lower San Joaquin River and tributaries: Levee and channel improvements, for flood control, along San Joaquin River from mouth of Merced River to San Joaquin Delta near Stockton, and on lower reaches of Stanislaus and Tuolumne Rivers by raising 1089, REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 and strengthening existing levees; construction of new levees; revetment of river banks where required; removal of accumulated snags in main river channel; and acquisition, by local interests, of flowage rights on natural overflow lands where necessary to insure continued effectiveness of channel storage on San Joaquin River. Project was modified to permit local interests to construct levees and channel improvements upstream from Merced River, where required in lieu of acquiring flowage easements. This project is an integral unit of overall plan for flood control and other purposes on San Joaquin River and tributaries and supplements reservoir units of overall plan involving flood control storage on Tuolumne and Stanislaus Rivers and in existing Friant Reservoir on upper San. Joaquin River, by providing required channel capacity for regulated flows. Cost estimate (July 1969) for existing project is $19,370,000, of which $13,070,000 is Federal cost and $6,300,000 non-Federal cost for lands and damages including relocations. Local interests constructed levee and channel improvement works in area adjacent to river above mouth Merced River in lieu of acquisition of flowage easements. Estimated cost of this work (July 1969) is $24,000,000. Left bank levee in Tuolumne River to Merced River reach is now considered active and is included in foregoing cost estimate. Existing project was adopted by 1944 Flood Control Act (H. Flood Control Committee Doc. 2, 78th Cong., 2d sess., contains latest published map); as modified by Public Law 327, 84th Congress, and 1962 Flood Control Act (H. Doc. 453, 87th Cong., 2d sess.). The 1944 Flood Control Act authorized $8 million for partial accomplishment of project. Further monetary authorizations of $2,500,000, $5 million, $13 million, $2 million, and $17 million were provided for this project by Public Laws 235 and 780, 83d Congress, and 85-500, 90-17, and 90-483, making a total monetary authorization of $47,500,000 available. Local cooperation. Tuolumne River Basin: In consideration of a Federal contribution toward first costs of construction, local interests must construct, maintain, and operate New Don Pedro Reservoir allocating 340,000 acre-feet of storage space therein for flood control, and operate such flood control reservation as prescribed by Secretary of the Army. A contract was negotiated in 1949 with local interests, comprising City and County of San Francisco and Turlock and Modesto Irrigation Districts, whereby they agreed to provide the above flood control storage in New Don Pedro Reservoir when constructed in exchange for Federal contribution. Construction of Cherry Valley Reservoir, and provisions of interim flood control storage therein as well as in existing Don Pedro and Hetch Hetchy Reservoirs, provided about 75 percent of flood control requirements for overall development, and Federal payments totaling $9 million made to local interests for this first phase. Second and final phase consists of construction of New Don Pedro Reservoir, operation of the flood control reservation in that reservoir, and cessation of operation of upstream reservoirs for flood control. Local interests have initiated construction of New Don Pedro Reservoir; bond issues for project received overwhelming approval of voters in elections held in November 1961 in Modesto, Turlock, and San Francisco. Federal Power Commission issued a license for project March 10, 1964. The irrigation districts approved acceptance of the FPC license May 23, 1966. Main dam contract was awarded in August 1967. Lower San Joaquin River and tributaries: Assurances were accepted by District Engineer January 6, 1956. Local interests fully complied with requirements for all Federal work completed or under contract, and indicated they will be able to fulfill local cooperation requirements for remaining work as scheduled. Ninety seven miles of the project total of 103 miles of levee construction have been transferred to and accepted by the State. Expenditures by local interests toward fulfillment of these requirements through May 31, 1969, were about $5,814,560. State revised their plan to include a bypass in lieu of improvement of existing levees along upper river reaches, thereby eliminating about 175 miles of levee construction along main San Joaquin River. Completed State project included construction of about 193 miles of levees, along with 18 major bridges and 7 control structures. Work extends along San Joaquin River from mouth of Merced River upstream to about 45 miles below Friant Darn near Fresno. Total cost of this plan is estimated (July 1969) at $24,000,000. Operationsa nd results duringfiscayl ear. New work: Tuolumne River Basin, including Cherry Valley and New Don Pedro Reservoirs-Engineering continued on New Don Pedro. Initial Federal contribution of $900,000 was made to the City and County of San Francisco and Turlock and Modesto Irrigation Districts. Project prevented an estimated $4,400,000 in damages from the January-February 1969 rainfloods 1090 SACRAMENTO, CALIF., DISTRICT and May-June 1969 snowmelt runoff. Lower San Joaquin River and tributaries Minor levee work on right and left banks, San Joaquin and Stanislaus Rivers was completed. Left bank levee in Tuolumne River to Merced River reach, previously inactive, was reclassified as 'active' in June 1969. Project prevented an estimated $10,800,000 in damages from the January- February 1969 rainfloods and May-June 1969 snowmelt runoff. Condition at end of fiscal year. Tuolumne River Ba- Sin: Cherry Valley Reservoir-first phase, completed in 1950; New Don Pedro Reservoir--second phase, con- Struction began in August 1967. Lower San Joaquin River and tributaries: Construction began in July 1956 and project is about 94 percent complete. Remaining work is recently reactivated improvement on left bank levee in Tuolumne River to Merced River reach. State of California construction on non-Federal portion of project above mouth of Merced River, initiated in fiscal year 1960, is complete. 18. MARTIS CREEK RESERVOIR, MARTIS CREEK, NEV. AND CALIF. Location. Reservoir to be on Martis Creek, a tributary of Truckee River, near Truckee, Calif.; intermittent channel improvements would be on Truckee River in Reno, Nev. (See Geological Survey quadrangles for areas.) Existing project. Provides for construction of 113- foot high rolled-earthfill dam to create a reservoir with gross storage capacity of 20,000 acre-feet, for flood control and future municipal and industrial water SUpply. In conjunction with the dam, the project provides for construction by local interests of intermittent channel improvements in Reno, Nev., necessary to provide a flood-carrying capacity of 14,000 cubic feet per second through the city. Approved cost estimate (July 1969) for existing project is $8,000,000, of Which $7,900,000 is Federal cost including $170,000 for basic recreation facilities, and $100,000 non-Federal cost for channel improvement in Reno, Nev. In addition, local interests have, over a period of years, expended about $200,000 for construction of flood control channels within city of Reno. This work is inadequate during major floods. Existing project was authorized by 1962 Flood Control Act (H. Doc. 435, 87th Cong., 2d sess., contains latest published map). Local cooperation. Local interests must provide a channel capacity of 14,000 cubic feet per second in Truckee River through Reno, Nev., including necessary modification and relocations of existing structures and facilities. Local interests must maintain completed channel as required to preserve channel capacity of 14,000 cubic feet per second; establish effective regulations to prevent any encroachment within channel in Reno, and insure that all bridges or other structures to be built or rebuilt across channel in Reno afford an adequate and unrestricted waterway; maintain channel of Truckee River between Reno and the California-Nevada State line clear of all floatable debris and other drift large enough to restrict bridge openings in Reno during floods; and adequately inform interests affected that project (reservoir and related channel improvements) does not provide protection against maximum floods. Formal assurances requested from the Carson-Truckee Water Conservancy District September 8, 1967 were furnished November 13, 1967. Operations and results duringfiscal year. New work: Land acquisition required for main dam was completed, $826,540. Engineering was continued including completion of plans and specifications for dam and appurtenances.

For description of completed improvements and authorizing act, see Annual Report for 1962. Improvements consist of Mariposa, Owens, Burns, and Bear Reservoirs and diversions from Black Rascal Creek to Bear Creek and from Owens Creek to Mariposa Creek. Total first cost for project was $3,- 899,259, of which $2,751,259 was Federal and $1,- 148,000 non-Federal for lands including relocations and channel improvement. Local cooperation. Fully complied with. 1091 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Operations and results during fiscal year. Maintenance: Ordinary maintenance and operation of the four completed reservoirs continued at costs as follows: Mariposa $5,379; Owens $3,481; Bear $3,434; and Burns $2,088. Structures were maintained in a serviceable condition. Runoff from drainage areas above Merced County stream group reservoirs was above normal for the year. (See table 35-K for maximum inflow storage and outflow for projects.) Outflows were less than channel capacity rates in the project streams. Projects prevented an estimated $9,000,- 000 in damages from the January-February 1969 floods. Condition at end of fiscal year. Construction was initiated March 1948, with construction of Mariposa Dam and Reservoir, which was completed in November 1948. Construction of Owens Dam and Reservoir, initiated in March, was completed in October 1949, and Burns Dam and Reservoir, initiated in July 1949 was completed in January 1950. Bear Dam and Reservoir, initiated in April, was completed in December 1954. Black Rascal and Owens Creek diversion channels and stream-gaging stations were completed in April 1956. Local interests completed channel enlargement and restoration of channel capacities of Miles, Burns, Owens, and Mariposa Creeks in 1956 at their expense. Improvement of Bear Creek and Black Rascal Slough, below their confluence, was deferred pending possible improvements downstream, outside limits of project. 20..MERCED RIVER, CALIF. Location. A tributary of San Joaquin River, northeast of town of Merced, Calif. (See Geological Survey topographic maps of the area.) Existing project. Federal interest in development is in flood protection afforded by multiple-purpose New Exchequer Reservoir, constructed on Merced River about 23 miles northeast of city of Merced by Merced Irrigation District of California as a part of a threereservoir multiple-purpose project. Project provides for enlargement of Exchequer Reservoir from existing 281,000 acre-feet for irrigation and power to 1,026,000 acre-feet for flood control, irrigation, power, and recreation uses. Dam is on Merced River about 62 river miles above the mouth. New Exchequer Dam is rockfill incorporating the former concrete structure at its upstream side. Powerplant at dam has installed capacity of 80,000 kilowatts with provision for future enlargement to 125,000 kilowatts. Af* terbay dam with capacity of about 9,730 acre-feet was provided about 6 miles downstream. Recreation facilities will be provided at both New Exchequer Reservoir and at the afterbay. Afterbay powerplant has a capacity of 9,000 kilowatts. Federal Government is contributing toward construction costs of New Exche" quer Dam and Reservoir only, exclusive of recreation and power generating facilities, in recognition of flood control accomplishments, to be provided. Ultimate Merced Irrigation District project will include construction of Bagby Reservoir (415,000 acre-feet) about 16 miles upstream from Exchequer Dam and Snelling Reservoir (190,000 acre-feet) about 10 miles downstream from Exchequer Dam and operation of the three reservoirs as a coordinated unit by Merced Irrigation District. Flood control operation of New Exchequer Reservoir will control flows to downstream channel capacity (6,000 cubic feet per second) and provide maximum flood control space of 400,000 acre-feet. Cost estimate (July 1968) for existing project is $27,910,000, of which $10,560,000 is Federal cost, comprising $10,450,000 direct Federal contribution to local interests and $110,000 incidental Federal cost for engineering and administration of funds. Amount is based upon cost allocation studies approved by the President of the United States April 27, 1964. Total Federal contribution is based on 37.6 percent of actual construction cost of New Exchequer Dam and Reservoir, including all necessary relocations, but exclusive of cost of power, and recreation facilities; however, the Federal contribution is limited to $19,400,000. Non-Federal cost included in the above amount is $17,350,000. Existing project was adopted by 1960 Flood Control Act (H. Doc. 322, 88th Cong., 2d sess.). Local cooperation. In consideration of a Federal contribution toward first cost of New Exchequer Reservoir, a formal agreement based upon cost allocation studies approved by the President of the United States April 27, 1964, was consummated with Merced Irrigation District April 28, 1964, and approved by the Secretary of the Army June 23, 1964. Agreement provides for operation of New Exchequer Reservoir to provide flood control benefits upon which monetary contribution is predicated and operation of flood control reservation in accordance with rules and regulations prescribed by Secretary of the Army. State of California adopted the Merced Irrigation District 1092 SACRAMENTO, CALIF., DISTRICT plan. Irrigation District was issued a Federal Power Commission permit (Project 2179) for project. State Water Rights Board approved Irrigation District application for water rights necessary for operation of project by decision D979 in August 1960. A revenue bond issue of $130 million was approved by voters in June 1961 to finance construction of the project. On July 15, 1964, the Irrigation District sold first block bonds of in amount of $36 million. Federal Power Commission issued a license effective March 1, 1964 (Project 2179), to Irrigation District for construction, operation, and maintenance of a single reservoir plan of development (New Exchequer Dam and afterbay including recreation as a project feature). Contract between Pacific Gas & Electric Co. and the Irrigation District on sale of power was completed June 1964. Main construction contract was awarded July 28, 1964. Closure was accomplished and the reservoir began operating for flood control in April 1966. Reservoir project was completed in September 1966. Operations and results during fiscal year. Engineering continued. Federal contribution of $923,157 was made to Merced Irrigation District. Runoff of Merced River above New Exchequer was much above normal for the year. Maximum storage of 1,018,600 acre-feet occurred June 30, 1969, as a result of the large snowmelt season runoff of 230 percent of normal. Maximum daily inflow to New Exchequer Reservoir was 33,500 cubic feet per second on January 21, 1969, and maximum daily outflow was 8,269 cubic feet per second on June 5, 1969. Project prevented an estimated $1,780,000 in damages from the January-February 1969 rainfloods and May-June 1969 snowmelt runoff. Condition at end of fiscal year. Merced Irrigation District initiated construction in June 1964; closure began in March 1965 and was completed in April 1966. Dam was completed in September 1966. As of June 30, 1969, total Federal contribution of $10,075,- 000 was made to Irrigation District. 21. MORMON SLOUGH, CALAVERAS RIVER, CALIF. Location. A distributary of Calaveras River, heads near town of Bellota, about 17 miles east of city of Stockton, Calif. Flows southwesterly to about 4 miles upstream from Stockton where it is diverted into Calaveras River through Stockton Diverting Canal. (See Geological Survey Sheet, Stockton quadrangle.) Existing project. Provides for improvement of Calaveras River System, between town of Bellota and San Joaquin River for flood control purposes. Improvements consist of minor channel enlargement of Mormon Slough below Bellota; channel enlargement of diverting canal and that reach of Mormon Slough immediately above diverting canal; levees along north bank of diverting canal, and along left bank of Calaveras River upstream of diverting canal for about one-half mile along both banks of Mormon Slough from diverting canal upstream to near Potter Creek, and along left bank of Potter Creek; and three drainage pumping plants on right bank of diverting canal. Plan provides for about 10 miles of new levees, 22 miles of enlargement of existing levees, 14 miles of channel enlargement, and 4.6 miles of channel clearing. Project will be coordinated with flood control operation of New Hogan Reservoir (see Sacramento District Improvement No. 10). Approved cost estimate (July 1969) is $5,380,000, of which $2,690,000 is Federal cost and $2,690,000 is non-Federal cost. Local interests also expended about $200,000 for construction of low levees in intermittent reaches along Mormon Slough, the diverting canal, and Calaveras River to provide some local flood protection. This protection is inadequate during major floods. Improvement was adopted by 1962 Flood Control Act (H. Doc. 576, 87th Cong., 2d sess., contains latest published map). Local cooperation. Local interests must furnish lands and rights-of-way, including spoil-disposal areas for construction; make relocations and alterations of roads, bridges, utilities, and other structures (except railroad facilities). However, since such costs are now estimated to exceed construction cost of project, Public Law 738, 74th Congress, permits local interests to be reimbursed for one-half of their excess expenditures over said estimated construction cost. In addition, local interests must hold the United States free from damages; maintain and operate completed works, including lower Calaveras River; and prescribe and enforce regulations designed to prevent encroachment of any type that would impair flood control effectiveness of work. State of California officially adopted project by chapter 915 of statutes of 1963, and by chapter 1438 of those statutes authorized the State Reclamation Board to furnish required assurances. Formal assurances requested from the State Reclamation Board in March 1966 were accepted by the District Engineer August 15, 1966. 1093 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Operations and results duringfiscal year.

Reservoir is on Kings River, about 25 miles east of Fresno, Calif., and channel improvements are on Kings River downstream from Lemoore weir, about 25 miles south of Fresno. (See Geological Survey quadrangles of area.) Existing project. Improvement is a unit in comprehensive plan for flood control and other related purposes for Sacramento-San Joaquin Basins. Project consists of a 429-foot-high concrete gravity dam, including a gated overflow section with a maximum discharge capacity of 391,000 cubic feet per second, creating a reservoir with a gross storage capacity of 1 million acre-feet, for flood control, irrigation, and related purposes. Outlet provisions for future power development are included in dam, but Federal construction of power-generating facilities is not authorized. Improvement also includes a limited amount of channel improvement on Kings River and its distributaries on valley floor about 25 miles south of Fresno. Channel improvement work will enlarge channel capacities and regulate flows in lower branches of the Kings River. There are nine public-use and recreation areas: one maintained by the Corps, four by Forest Service, three jointly by the Corps and concession, and one by Fresno County. Also, five boat access-only areas are maintained by the Corps on the south side of reservoir. Approved cost estimate (July 1969) is $41,250,- 000, of which $40,700,000 is Federal (including $14,- 000 for basic recreation facilities) and $550,000 non- Federal for rights-of-way for downstream channel improvements.

Estimated Federal cost of recreational facilities for Pine Flat Reservoir, to be funded from Code 710 appropriations is $905,100 (July 1969) exclusive of recreation facilities previously provided at a cost of $14,000. In addition, Federal cost of recreation facilities for Pine Flat Reservoir, funded from Public Works Acceleration Executive Act of 1962 appropriations, was $239, 235 (July 1963), exclusive of recreation facilities provided from regular project and Code 710 funds. Operation and maintenance of dam and reservoir is Federal responsibility. Existing project was adopted by 1944 Flood'Control Act (H. Doc. 630, 76th Cong., 3d sess., contains latest published map). Local cooperation. Local interests must reimburse the Federal Government for first costs allocated to irrigation functions of reservoir portion of project in accordance with Reclamation Law. Under provision of War Department Civil Appropriations Act of 1947, the Secretary of War, with concurrence of Secretary of the Interior, determined allocation of cost to irrigation should be set at an amount not to exceed $14,250,000. In addition, local interests must pay 37.4 percent of annual maintenance, operation, and replacement costs of dam and reservoir allocated to irrigation function. Repayment contracts between Bureau of Reclamation and the local water users for the irrigation use of the reservoir were executed December 23, 1963. Bureau is administering the contracts in accordance with reclamation law; however, local interests are testing in court the validity of reclamation law in regard to the Pine Flat contracts. Prior to execution of the final contracts, the Bureau provided conservation water to local interests under an interim contract. Irrigation interests paid $10,054,138 for irrigation services through June 30, 1968. With respect to the downstream channel improvements, section 3, Flood Control Act of June 22, 1936, applies. Kings River Conservation District represents local interests; assurances were accepted November 20, 1959. Local interests have furnished all requirements for construction rights-of-way for construction of channel improvements required to date. Three concessionaires (one each at Deer Creek, Lombardo's Fishing Village, and Trimmer area) provided public-use facilities in accordance with lease agreements with Secretary of the Army. Estimated cost of facilities installed by these concessionaires is $132,000. Fresno County developed public-use facilities on an 85-acre tract immediately downstream from dam for picnicking, camping, swimming, and playground activities, at an estimated cost of $41,000 under provisions of a license agreement. Forest Service operates a picnic area at upper end of reservoir and two campgrounds and a picnic area at sites along reservoir perimeter. Total cost of development of these sites is about $36,500. 1096 SACRAMENTO, CALIF., DISTRICT Licenses.

Operation and maintenance of dam and powerplant will be the responsibility of the Federal Government. Approved cost estimate (July 1969) for existing project is $166,- 000,000 all of which is Federal cost, including $2,- 400,000 for basic recreation facilities. For future non- Federal reimbursement, see Local cooperation paragraph. Existing project was adopted by 1966 Flood Control Act. (H. Doc. 501, 89th Cong., 2d sess.). Local cooperation. With respect to the dam and reservoir, local interests, represented by the State of California, must (a) reimburse the Federal Government the portion of joint use first costs allocated to water supply (36.0 percent) and to power (10.3 percent) in addition to specific power costs (presently estimated at $21,800,000), (b) pay, contribute in kind, or repay (which may be through user fees) with interest, onehalf of the separable cost of the project allocated to recreation and fish and wildlife, and (c) bear all costs of operation, maintenance, and replacement of recreation and fish and wildlife lands and facilities. (Public Law 89-72, The Federal Water Projects Recreation Act.) On 29 June 1966, the California Resources Agency stated its intention to provide necessary leadership in furnishing the assurances of local cooperation required by the Federal Water Project Recreation Act. Operation and results during fiscal year. New work: Preconstruction engineering studies and design mernoranda were continued. Condition at end of fiscal year. Preconstruction planning was continued. 34. NEW MELONES RESERVOIR, CALIF. Location. On Stanislaus River about three-quarters mile downstream from existing Melones Dam and about 35 miles northeast of city of Modesto. (See also Improvement No. 17 for Tuolumne River Basin and Lower San Joaquin River and tributaries.) (See Geological Survey quadrangles of the area.) Existing project. Provides for construction of (a) a dam to create a reservoir with gross storage capacity of about 2,400,000 acre-feet for flood control, irrigation, power, general recreation, fish and wildlife, and other purposes, and (b) a powerplant below the dam with an installed capacity of 150,000 kilowatts. Upon completion of construction of dam and powerplant by the Corps, the project shall become an integral part of Central Valley project and operated and maintained by Secretary of the Interior pursuant to Federal reclamation laws, except that the flood control operation of the project shall be in accordance with rules and regulations prescribed by Secretary of the Army. Maintenance of Stanislaus River channel from Goodwin Dam to San Joaquin River to a capacity of at least 8,000 cubic feet per second will also be Corps responsibility. Approved estimated (July 1969) Federal cost is $145 million. For future non-Federal reimbursement, see Local Cooperation paragraph. In addition, local interests expended $300,000 for levees along lower reaches of Stanislaus River. Existing project was adopted by 1962 Flood Control Act (H. Doc. 453, 87th Cong., 2d sess., contains latest published map). This act modified original authorization adopted by 1944 Flood Control Act. (H. Flood Control Committee Doc. 2, 78th Cong., 2d sess., contains latest published map), as modified by Public Law 327, 84th Congress. The 1944 Flood Control Act authorized $8 million for partial accomplishment of project. Further monetary authorizations of $2,500,000, $5 million, $13 million, $2 million and $17 million were provided by Public Laws 235 and 780, 83d Congress, 1102 SACRAMENTO, CALIF., DISTRICT and 85-500, 90-17, and 90-483, ma4kig a total monetary authorization of $47,500,000 available for the basin plan comprising Lower San Joaquin River and tributaries, including Tuolumne and Stanislaus Rivers, Calif. Local cooperation. Based on approved preliminary cost allocation studies (July 1965) local interests will be required to pay 35.2 percent of first cost and 12.7 percent of annual operation and maintenance costs allocated to irrigation. In addition, 31.1 percent of first cost and 62.5 percent of annual cost would be allocated to power. Local interests must also maintain existing private levees along Stanislaus River from Goodwin Dam to San Joaquin River and prevent encroachment on channel and floodway between levees so as to preserve safe carrying capacity throughout that reach of at least 8,000 cubic feet per second. Recovery of costs allocated to irrigation and power will be responsibility of Bureau of Reclamation. Reimbursement of costs will be in accordance with Bureau of Reclamation's policies and procedures for the Central Valley project. State of California officially adopted project by chapter 918 of statutes of 1963, and by chapter 1438 of those statutes authorized State Reclamation Board to furnish required assurances. The Board by letter dated December 13, 1963, stated it will furnish required assurances when formally requested to do so. Operations and results duringfiscal year. New work: Engineering studies pertaining to preparation of de- Sign memoranda were continued. Plans and specifications were continued for relocations, dam and appurtenances, powerplant, and diversion facilities. Total engineering costs, including contracts, were $906,- 657. Land acquisition activities were continued at cost of $94,623. Scaling contract was completed at cost of $578,245. Miscellaneous minor construction work in connection with dam and roads was continued by hired labor at cost of $33,323. The 1969 flood season in the Central Valley was climaxed by serious snowmelt flood runoff in the southern San Joaquin Basin during May-June 1969. If New Melones Reservoir had been completed and in operation during the January-February 1969 rainfloods and the May-June 1969 snowmelt runoff, flows would have been completely controlled to non-damaging stages and damage amounting to an estimated $3,- 000,000 would have been prevented. During fiscal year 1966-1969 period, about $750,000 of Federal funds was expended for flood fighting and emergency repairs, snagging and clearing on Stanislaus River below damsite. Condition at end of fiscalyear. Construction was initiated in August 1966; project is about 6 percent complete. General Investigations 35. SURVEYS See table 35-Q. 36. COLLECTION AND STUDY OF BASIC DATA Flood plain information studies were made at fiscal year costs of $ 134,339.

COLLECTION AND STUDY OF BASIC DATA International water studies. The Columbia River Treaty between Canada and the United States relating to International Cooperation in Water Resources Development of the Columbia River Basin was signed at Washington, D.C. on January 17, 1961. Implementation of the Treaty by the Entities under the guidance of the Permanent Engineering Board and the Coordinating Committee has continued. An operating program has been agreed to and established for Canadian storage operation through June 1971. The Entities have established two permanent committees, a Flood Control Operating Committee and a Hydrometeorological Committee. All present International Task Forces are to be disbanded when the Flood Control Plan has been completed, except for portions affecting Libby project in Montana, and Mica project in British Columbia pending possible modification of the International Joint Commission Orders for Kootenai Lake. Costs during fiscal year were $32,516. Flood Plain Information Studies. Field surveys and other means were used to collect basic flood data to compile channel cr6ss sections, water surface profiles, stage hydrographs and flooded-area maps for inclusion in two flood plain information reports currently near completion. A narrative including a description of the flood situation along each stream studied, also, was prepared for publication in both reports. The reports and corresponding streams are identified below: 1. Milwaukie - Oak Grove - Lake Oswego area, Oregon, Flood Plain Information Report - Willamette River and Johnson, Kellogg and Mr. Scott Creeks. 2. Oregon City - Gladstone - West Linn area, Oregon, Flood Plain Information Report - Willamette, Tualatin and Clackamas Rivers and Abernathy Creek. Final preparation work was accomplished on three additional reports listed as completed in table 37-P. Costs for these studies during the fiscal year were $135,688. Total costs for collection and study of basic data were $168,203. 63. SURVEYS 65. RESEARCH AND DEVELOPMENT Fiscal year costs were $771,181 of which $72,891 Water quality investigation. Program of observing 1162 PORTLAND, OREG., DISTRICT Water temperatures and monitoring dissolved oxygen at key Willamette Basin reservoirs was continued. The Federal Water Pollution Control Administration and Fish Commission of Oregon were active in monitoring. Interim report on District Water Quality Activities for 1968 was submitted to higher authority. Stored water in Willamette Reservoirs was released in substantial quantities in summer of 1968 to alleviate a fishery problem caused by low levels of dissolved oxygen in the lower Willamette River. The Portland District assisted in financing a special river temperature investigation in the lower Columbia River, a program to study the feasibility of using Columbia River water as a coolant for a nuclear power plant. The turbidity problem at Hills Creek was studied in depth during the summer of 1968. No firm decision as to problem source or solution to the problem has been determined. Investigation is being continued as a joint interagency program. Hydrologic studies. Reservoir temperatures are being continuously analyzed and procedures for making synthetic reservoir temperature studies are being refined. A consulting firm was retained to study a specific project for the purpose of enhancing the program. Programs for using the computer to make hydrologic studies are being expanded and refined. An automated reporting hydrologic network is being studied for the Willamette Basin to eliminate the manual collection and processing of a vast amount of basic stream, reservoir and weather information collected daily throughout the basin. Procedures for maximization of benefits from storage projects are being investigated. Civil Works Investigations. A concrete test panel with an epoxy mortar coating in both a 3/8-inch and a 3/4-inch thickness was installed in the Detroit Test Conduit (ES 825) and testing was begun in July 1968. The test was terminated after several hours of operation because of failure of the test panel. In April of 1969 three additional concrete test panels were poured. During the month of May one of these test panels was given a 3/8-inch-thick epoxy mortar coating and the other was given a 3/4-inch-thick epoxy mortar coating. Testing of one of these panels was initiated in the latter part of June. No tests were conducted in the Detroit Test Chute (ES 826) during the year and work consisted essentially of analysis of test data obtained previously. Computer programs. Continued with the development, modification, and utilization of programs to make water resource system analysis, flood forecasting, flood routings, and derivation of design floods. Also, computation of horizontal and vertical control in survey work is a continuing program. The conversion of programs for use on the IBM 360 Model 50 installed at the North Pacific Division is continuing. In addition, Fortran programs have been written in the Engineering Division in the.fields of Structures, Economic Studies, and Water Control. Total research and development costs were $93,170. 1163 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 COST AND FINANCIAL STATEMENT See Section in Text Project Funding Total to FY 1965 FY 1966 FY 1967 FY 1968 FY 1969 June 30,1969 Appropriated Cost Maintenance: Appropriated Cost Rehabilitation: Appropriated Cost 9.

Existing project. Plan of improvement provides for construction of a revetted levee approximately 1,200 feet long, and channel renovation. Protection will be provided against a flood of 8,800 cfs which has an estimated exceedence interval of about once in 200 years. Project was adopted by Chief of Engineers March 11, 1968 under authority of section 205, 1948 Flood Control Act, as amended. Estimated costs (July 1969) are $113,500 Federal and $1,750 non-Federal for rights-of-way. Local cooperation. Section 3, Flood Control Act of June 22, 1936, as amended, applies. A letter of intent to meet requirements of local cooperation has been received from village of Kendrick. Operations and results during fiscal year. Preparation of plans and specifications was completed. Condition at end of fiscal year. Project is ready for construction. 3. BLACKFOOT RESERVOIR, BLACKFOOT RIVER, IDAHO Location. On Blackfoot River in Caribou County, Idaho, about 40 miles southeast of city of Blackfoot. (See Geological Survey quadrangle sheets Paradise Valley, Cranes Flat, Portneuf, and Henry for location and surroundings in immediate vicinity of project). Existing project. Blackfoot Dam and Reservoir is owned and operated by Fort Hall Agency of Bureau of Indian Affairs, Department of Interior. Main dam which is 52 feet high, is a rockfill structure with a concrete core. China Hat Dam, an earthfill structure, closes an arm of reservoir near its upstream end to minimize storage loss due to seepage in pervious formation of that area. Existing main dam structure includes a 3,800-cubic-foot-per-second spillway on the right abutment and an outlet tunnel in left abutment with a capacity of 2,700 cubic feet per second. Reservoir has a usable storage capacity of 413,000 acre-feet at design maximum water surface elevation 6124. However, due to experience with seepage losses from southern end of reservoir, operating level has been limited to about elevation 6120, or about 340,000 acre-feet storage capacity. Water stored in reservoir is used to irrigate lands in Fort Hall Indian Reservation in vicinity of Blackfoot and south. Recommended modifications of the project would provide 38,000 acre-feet additional storage capacity for flood control. Modifications would permit operation of reservoir for flood control to a maximum water surface elevation of 6126. The spillway capacity would be increased to 15,800 cubic feet per second by lowering crest elevation from 6118.5 to 6111.7 and increasing spillway width from 52 feet to 93 feet. Spillway would be equipped with new gates. Outlets works would be modernized and rehabilitated for flood control operation. China Hat Dam would be raised 8 feet and Idaho State Highway No. 34 would be raised in grade for approximately 1/2 mile along with grade raising of two existing bridges. Recommended modification was authorized by Flood Control Act of 1962. Construction to be accomplished by the Corps, with continued operation of project by Bureau of Indian Affairs. Estimated Federal cost of proposed modifications (July 1969) is $2,240,000. Local cooperation. None required. Operations and results during fiscal year. Preparation continued of a general design memorandum which incorporates design changes required for increased spillway design flood. Condition at end of fiscal year. Modification of Blackfoot Dam and Reservoir in interest of increased flood control for Blackfoot River Basin was first presented as a potential project in review report for Upper Snake River Basin dated 1961, which was prepared jointly by Walla Walla District and Regional Office of Bureau of Reclamation in Boise, Idaho. That review report was authorized by a Senate Resolution adopted March 19, 1954, which requested a review of House Document 531, 81st Congress, 2nd session, with particular reference to Upper Snake River Basin above Weiser, Idaho. In referenced review report, modification of Blackfoot Dam and Reservoir was presented as one of the potential projects warranting early consideration for construction. Interim report on modification of Blackfoot Dam and Reservoir, dated March 1962, included additional information and analysis of February 1962 floods and confirmed project economic feasibility. It is on this latter report that congressional authorization is based. Design memorandum for hydrology is complete. Foundation exploration drilling at China Hat Dam and at Black" foot Dam is complete. General Design Memorandum is 95 percent complete and is scheduled for submission in July 1969. 1214 WALLA WALLA, WASH., DISTRICT 4.CATHERINE CREEK RESERVOIR, OREGON Location.

Improvement will pro- Vide for flood control, irrigation, municipal and industrial water supply, water quality control, fish and Wildlife, recreation, and downstream hydroelectric power. Project was authorized by 1965 Flood Control Act. Estimated Federal cost (July 1969) is $10,800,000. Local cooperation. The Water Supply Act of 1958 as amended applies. The city of Union, Oregon, by letter dated September 27, 1961, has provided assurances of Willingness and ability to meet requirements. Reimbursable costs are presently estimated to be $347,000 for construction and $1,000 annually for operation, maintenance, and replacement. The Federal Water Project Recreation Act of 1965 applies. This requirement for local cooperation was added after submittal of the Survey Report. Negotiations are now underway to obtain a letter of assurance from a responsible non-Federal public body. Reimbursable costs are estimated to be $337,000 for construction and $31,000 annually for operation, maintenance, and replacement. In accordance with reclamation law, local irrigation interests will be required to repay portion of first costs and annual operation, maintenance, and replacement costs of dam and reservoir allocated to the irrigation function, currently estimated at $1,561,000 and $12,- 300, respectively. Portion of construction cost beyond ability of irrigators to repay will be returned to reclamation fund from revenues derived from disposition of power marketed through the Bonneville Power Administration. Irrigation districts now being organized Will contract for repayment of cost allocated to irrigation. Operations and results during fiscal year. Preparation of the general design memorandum was started with emphasis on gathering basic field information and coordination with the Bureau of Reclamation and other agencies. Mapping and foundation explorations were carried on to the extent of available funds. Condition at end of fiscal year. Preconstruction planning is approximately 14 percent complete and no construction has been done. 5. COLUMBIA RIVER BASIN, LOCAL FLOOD PROTECTION PROJECTS Location.

Construction (cofferdam) started in July 1965. Entire project, including land acquisition, is estimated to be 15 percent complete. 26. LOWER MONUMENTAL LOCK AND DAM, SNAKE RIVER,WASH. Location. On Snake River at head of Ice Harbor pool, about 45 miles northeast of Pasco, Wash. Existing project. Provides for construction of a dam, powerplant, navigation lock, relocation of railroads and highways above proposed pool level at elevation 540 feet mean sea level, and appurtenant facilities, creating a slack water pool about 30 miles long extending to site of Little Goose lock and dam. The dam, located at upper end of pool created by Ice Harbor dam, will raise water surface about 100 feet, and concrete gravity with earthfill and rockfill abutments is 135 feet high (above streambed), and 3,800 feet long (including abutments, spillway, navigation lock and powerhouse). Fish ladders will be provided, one at each end of the dam. Powerhouse will have three 135,000-kilowatt units installed initially, and a substructure for three additional units, for an ultimate total of six 135,000-kilowatt units, or 810,000 kilowatts. Spillway will be 508 feet long, and overflow crest at elevation 483 feet above mean sea level will be surmounted by 8 radial gates, each 50 feet wide and 60.5 feet high. Deck is at elevation 553 feet, and provides a service road and track for gantry crane. Navigation lock is single-lift type, with lock chamber 86 by 67k feet, providing a minimum depth of 15 feet over lock sills. Reservoir capacity at elevation 540 is 376,000 acre-feet. Existing project was authorized by 1945 River and Harbor Act (P.L. 14, 79th Cong., 1st sess.). Estimated total cost for new work (July 1969) is $177,102,000 including $177 million Corps fundS, $87,000 Coast Guard funds for navigation aids, and $15,000 for value of public-domain lands. Local cooperation. None required. Operations and results duringfiscal year. New work, hired labor: Engineering and design work continued. New work, contract: Relocations of highways and railroads were completed, except for deferred con* struction which covers a period of five years. Construction of Marmes Rockshelter protective works 1224 'WALLA WALLA, WASH., DISTRICT Was completed on schedule, and the creation of the reservoir began on February 21, 1969. Prior to raising pool, all essential clearing below pool level was ac- Complished in the reservoir area, and the first-stage development of recreation and public-use areas was Initiated. Maximum operating pool elevation 540 was reached February 26. Upstream navigation floating guidewall was completed and installed. Assembly of turbines, generators, and associated mechanical and electrical equipment continued. Permanent fish ladder became operative on February 27, and the first vessel passed through the lock on April 15. The first generator went on-the-line May 28. Operation and maintenance: Routine operation and maintenance expenditures, payable from Operation and Maintenance, General funds, began on May 1, 1969 following placing navigation lock in operation. Approximately 96,606 megawatt hours of electrical energy were delivered to Bonneville Power Administration, the marketing agency. Condition at end offiscalyear. Final design work is about 98 percent complete. Construction started in fiscal year 1961. The entire project is about 92 percent Complete. Completed items include majority of land acquisition, relocations (except deferred construction), dam, spillway, lock, fish ladders, Marmes Rockshelter protective works, upstream floating guidewall, and the first of three generators. Work continued on powerhouse and installation of mechanical and electrical equipment. The first-stage development of recreation and public-use areas is 98 percent complete. Reservoir clearing is substantially complete except for removal of the piers on the Snake River bridge at Riparia. 27. MCNARY LOCK AND DAM, COLUMBIA RIVER, OREGON AND WASHINGTON Location. On Columbia River 292 miles above mouth, near Umatilla, Oregon, and 3 miles above mouth of Umatilla River. Existing project. A dam, powerplant with 14- POwer-unit generating installation, navigation lock, fishways, attendant buildings and grounds, levees, drains, pumping plants, incidental irrigation, and modification of railroad bridges over Columbia and Snake Rivers in order to eliminate hazards to navigation. For more detailed description see page 1990 of Annual Report for 1962. Existing project was authorized by 1945 River and Harbor Act (H. Doc. 704, 75th Cong., 3d sess.). Estimated total cost for new work (July 1969) is $296,212,000, consisting of $297,000,000 Corps of Engineers funds, a net reduction of $851,000 for cost and property transferred from project, and $63,000 for Coast Guard navigation aids. Construction of additional recreation facilities for completed project is estimated to cost $1,720,- 000, raising total project cost to $297,932,000. Local cooperation. None required. Operations and results duringfiscal year. New work: Work was continued under an agreement with NP Railway Co. which provides that they design and reconstruct their Snake River Bridge No. 3. Alteration of bridge substructure was begun during fiscal year. Draft of an agreement with Union Pacific Railroad for them to prepare preliminary plans, cost estimates, and cost apportionment for modification of their Columbia River bridge was disapproved because of stipulated life of existing bridge. Negotiations with railroad company were resumed to consummate an agreement providing a lesser remaining life. Code 710 Activity: Planning was continued for further development of recreation facilities in reservoir area and for acquisition of additional land at Cold Springs site. Design for Cold Springs area is complete. Operation and Maintenance: Normal operation and maintenance of project continued. Approximately 6,495,404 megawatt hours of electrical energy were delivered to Bonneville Power Administration, the marketing agency. Installation of equipment at McNary powerhouse for remote control of lower Snake River dams continued in conjunction with Ice Harbor Dam now on remote control. A contract for $141,000 was completed for construction of an additional pumphouse at Pasco Levee 12-1. A contract for $38,308 was awarded for resurfacing project roads. Electrical failure of generating unit No. 13 resulted in an abnormal maintenance cost of $52,800. Condition at end of fiscalyear. Construction of existing project started May 1947 and is 97 percent complete (June 1969). Project was placed on a permanent operating basis and pool raised to normal operating elevation 340 in December 1953. Except for maintenance interruptions, all 14 power units have been in commercial operation since February 1957. Modification to two railroad bridges over Columbia and Snake Rivers remains to complete project. Northern Pacific Railway Co. is proceeding with reconstruction of its Snake River Bridge No. 3, and 1225 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 has awarded a contract under which work is progressing on bridge substructure. Modification involves funding by two projects - McNary Lock and Dam and Lower Monumental Lock and Dam. When Northern Pacific Snake River branch of the railway was condemned in conjunction with Lower Monumental Lock and Dam project, traffic was :subsequently rerouted over Northern Pacific Snake River Bridge No. 3. In order to provide for increased traffic, load bearing capacity of bridge is therefore to be upgraded concurrently with navigation modification. Negotiations are in progress with Union Pacific Railroad Co. to enter into an agreement whereby the railroad company would design, modify, and supervise work on its Columbia River bridge. Progress, however, has been slow due to difficulties in resolving differences of opinion regarding determination of remaining life of existing bridge. 28. SNAKE RIVER DOWNSTREAM FROM JOHNSON BAR LANDING, OREG., WASH., AND IDAHO Location. On Snake River downstream from Johnson Bar Landing, river mile 231. Snake River, which is largest tributary of Columbia River, rises in Yellowstone National Park, in western part of Wyoming, flows generally westerly for about 1,000 miles and empties into Columbia River near Pasco, Washington, 324 miles from Pacific Ocean. Previous projects. For details see Annual Reports, page 1981 for 1962, page 1991 for 1915, page 2246 for 1903, and page 1986 for 1906. Existing project. River and Harbor Act of 1945 (P.L. 14, 79th Cong., Ist sess.) authorized construction of such dams as are necessary and open channel improvements for purposes of providing slackwater navigation and irrigation between mouth of Snake River and Lewiston, Idaho. This authorization modifies previous authorizations only for that portion of improvement below Lewiston, Idaho. Acts of June 13, 1902, and August 30, 1935, as they pertain to open river improvement from Lewiston, Idaho, to Johnson Bar Landing are part of existing project. Improvements included in existing project and estimated Corps cost are Ice Harbor Lock and Dam, river mile 9.7, $157,250,000, including $1,350,000 for recreation facilities on completed project; Little Goose Lock and Dam, $152,000,000; Lower Granite Lock and Dam, $216,000,000; Lower Monumental Lock and Dam, $177,000,000; and Open-river improvement, Lewiston to Johnson Bar Landing, $34,613. Total estimated cost is $702,284,613. Local cooperation. None required. Terminalfacilities. Six privately owned grain facilities on Snake River. Four of these are on open river and limited in use.for waterway shipping due to shallow channel depths. Two are on Ice Harbor pool.There are three privately owned terminals below Ice Harbor Lock and Dam - one grain and two petroleum. In addition, there are four publicly owned mareinas and 17 small boat launching ramps, all open to public use. Facilities are adequate until slackwater navigation is available and shipping volume increases following completion of dams now under construction above Ice Harbor. Operations and results during fiscal year. See individual reports for Lower Granite, Little Goose, Lower Monumental and Ice Harbor locks and dams. On Snake River from Lewiston, Idaho, to Johnson Bar Landing reconnaissance and condition surveys were conducted. Navigation aids were repaired and channel was improved at Cottonwood Rapids. Condition at end of fiscal year. Costs of existing project were $451,522,844 for new work and $5,697,767 for maintenance, a total of $457,220,611 regular funds. Additional cost of existing project was $82,500 for new work from contributed funds for artificial spawning channel at Ice Harbor Lock and Dam project. (See table 39-H for summary of status of work on existing and previous project authorization.) 29. OTHER AUTHORIZED MULTIPLE PUl" POSE PROJECTS See table 39-I. General Investigations 30. SURVEYS Total cost of surveys during fiscal year was $219, 173. Of that amount $976 was for navigation studies, $189,361 for flood control studies, and $28,836 for cooperative studies with Soil Conservation Service and Bureau of Reclamation. 31. COLLECTION AND STUDY OF BASIC DATA During fiscal year flood hazard information waS 1226 WALLA WALLA, WASH., DISTRICT provided to agencies from states of Idaho, Oregon and Washington, and to numerous Federal agencies. Private organizations were also provided flood hazard information for locations where data were readily available. Flood plain information reports were completed for Walla Walla River tributaries in Walla Walla County, Washington; South. Fork of Palouse River and Missouri Flat Creek in Pullman, Washington; and Payette River in vicinity of Payette, Idaho. Flood plain information report of Canyon Creek at Canyon City and John Day, Oregon was complete at end of fiscal year but will not be presented to local people until first quarter of fiscal year 1970. Flood plain informnation reports for Portneuf River at Pocatello, Idaho, and Umatilla River in vicinity of Pendleton, Oregon, are 60 to 70 percent complete. Total fiscal year costs were $98,176. (See table 39-J on completed flood plain studies.) 32. RESEARCH AND DEVELOPMENT Hydrologic investigations to improve forecasting procedures with respect to floods and seasonal runoff volumes were continued. Studies were made of cause of floods and of flood frequencies for various size areas. Fiscal year cost of these studies was $5,206. Engineering studies consisting of finite element analysis of gravity lock walls were alsqperformed during fiscal year at cost of $1,629. Combined fiscal year costs of all research and development were $6,835. 1227 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 TABLE 39-A COST AND FINANCIAL STATEMENT See Section Total to in Text Project Funding FY 65 FY 66 FY 67 FY 68 FY 69 June 30, 1969 i $ 4,541 $ 9,400 3,763 1,458 46,000 24,000 25,978 38,230 - - $ 850 9,479 10,000 11,428 2.

Anchorage is in south-central Alaska on southeast shore of Knik Arm and north of Turnagain Arm near junction with Cook Inlet. (See Coast and Geodetic Survey Charts 8553 and 8557.) Existing project. Provides for a deepwater harbor by dredging adjacent to existing and proposed municiPal docks to a depth of 35 feet below mean lower low Water and constructing two jetties of other protective Works where required, along northerly and southerly ends. Tidal range between mean lower low water and mean higher high water is 28.1 feet and extreme range is 40.7 feet, based on pre-earthquake data. Large ice masses in winter months form into floe ice making it extremely hazardous for small-boat navigation during that period. Cost estimate for new work (1968) is $7,200,000. Existing project was adopted by 1958 River and Harbor Act (H. Doc. 34, 85th Cong., Ist sess.). Local cooperation. Local interests must provide easements, rights-of-way, and spoil-disposal areas; hold the United States free from damages; and construct wharf facilities adequate for handling of cargo. Terminal facilities. Four wharves capable of handling ocean going vessels and open for public use consist of two owned by the city, of which one is an oil handling and bunkering facility, and two are privately owned. Five additional wharves are privately owned and used for industrial purposes. A government owned wharf, damaged by the 1964 earthquake, has been reduced in size through removal and deterioration and is unuseable. Expansion of the existing city dry cargo wharf is underway.

Tidal range between mean lower low water and mean higher high water is 9.9 feet. Extreme range is about 18 feet. (See table 40-B for authorizing legislation.) Local cooperation. City of Sitka agreed to meet all 1237 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 necessary requirements and will also provide bulkheads to retain spoil material. Terminal facilities. There are 13 piers, wharves, and floats in Sitka Harbor. Four privately owned and operated wharves are open for public use. City of Sitka owns three float systems which are open for public use for mooring and servicing small craft. Former Navy facilities are being used by Alaska Native Service. Remaining facilities are used for industrial purposes. Facilities are considered adequate. Operations and results during fiscal year. Regular funds, new work: On site studies were continued to determine the cause and extent of damage to the moored boats in the small-boat harbor. Condition at end of fiscal year. Indian Rock and an isolated boulder were removed and channel was completed on easterly side of Harbor Rock in 1937. During design stage the basin area was enlarged to 15 acres to accommodate expanded vessel activity, and the breakwater design was revised. Project depth was available in channel in May 1948. Construction of breakwater protecting Crescent Bay smallboat basin and dredging of Forest Service Basin was initiated July 30, 1964 and was completed December 24, 1965. 10. STIKINE RIVER, ALASKA Location. Rises in northwestern Canada and flows southwesterly through Canada for about 200 miles, then about 30 miles westerly across Panhandle of Alaska to Sumner Strait. Mouth of river is on coast of mainland about 3 miles north of Wrangell. (See Coast and Geodetic Survey Chart 8201.) Existing project. Snagging Stikine River from its mouth about 30 miles to Canadian border. No data available concerning stages of high and low water in river. At mouth, tidal range between mean lower low water and mean higher high water is 13.9 feet, and maximum range is about 25 feet. Tidal effects have been reported at a distance of 20 miles from the mouth. Existing project was adopted by 1935 River and Harbor Act (H. Doc. 210, 72d Cong., 1st sess., contains latest published map of locality.) Local cooperation. None required. Terminalfacilities. None along Alaskan portion of river. Vessels operating on Stikine River are dependent on terminal facilities at Wrangell Harbor. Two privately owned wharves serving general cargo and passenger terminals, one of which includes a coldstorage facility, are open for public use for mooring and servicing small craft, and two privately owned floats serve oil-handling facilities. Small-boat harbor facilities accommodate about 200 vessels. Operations and results during fiscal year. Clearing of 35.7 acres of trees along the river bank to eliminate potential snags was accomplished with regular maintenance funds by contract during June 1969 at a cost of $6,370. Condition at end of fiscal year. Removal of snags from the river between its mouth and the Canadian border was accomplished as needed by contract under maintenance funds from 1938 to 1964 when annual snag removal was initiated. Removal of snags and clearing of trees on shore as potential snags was accomplished October 1967 through May 1968 and again in June 1969. 11. WRANGELL HARBOR, ALASKA Location. Wrangell Harbor is located, on the west side of the northern end of Wrangell Island, 824 miles from Seattle and 160 miles from Juneau. (See U. S. Coast and Geodetic Survey Charts Nos. 8164, 8161, and 8201.) Existing project. This provides for a rubblemound breakwater 300 feet long to protect the southern portion of the outer harbor; dredging a mooring basin 600 feet long, 400 feet wide, and 10 feet deep below mean lower low water within the protected area; an inner basin in the tide flat area east of Shakes Island, 325 feet wide and 550 feet long and a connecting channel 120 feet wide and approximately 530 feet long from the outer mooring basin all at a depth of 10 feet at mean lower low water; and construction of a rock mound breakwater 320 feet long on the reef north of Shakes Island. The range between mean lower low water and mean higher high water is 15.7 feet. The extreme tidal range is 26 feet. Heavy swells, dangerous to small fishing boats, are caused by the wind, which causes an additional rise of about 1 foot. Construction of the breakwater north of Shakes Island was placed on inactive status as material to be used from the inner basin was unsuitable and the breakwater considered unnecessary for safe moorage of vessels. The cost of this portion was last revised in 1956 was estimated to be $6,500. (See table 40-B for authorizing legislation.) Local cooperation. Fully complied with. Terminal facilities. There are eight wharves and floats in Wrangell Harbor. Two privately owned 1238 ALASKA DISTRICT Wharves serving general cargo and passenger terminals, one of which includes a cold storage facility, are Open for public use. The remaining wharves serve Various industrial purposes. One of the floats is publily Owned and is open for public use for mooring and servicing small craft, and two privately owned floats serve oil-handling facilities. Additional mooring floats to accommodate 200 small boats are required. Operations and results during fiscal year. Regular funds, maintenance: Maintenance dredging in the northern portion of the inner basin connecting channel and along the easterly side of the outer basin was accomplished Sept and Oct 1968 with the removal of 13,644 cu yds of material at a cost of $53,050.

The Board comprises 7 senior engineer officers. Normally the Chairman is the Deputy Chief of Engineers. Five members are Division Engineers Statutory duties of the Board as set forth in the act of June 13, 1902, and subsequent acts and amendments are: (a) to conduct an independent review of SUrvey reports covering projects for river and harbor, flood control, and multiple-purpose improvements prepared by the Corps in response to an act of the Congress or a resolution of the House or Senate Public Works Committees, and to report its conclusions and recommendations thereon to the Chief of Engineers, who forwards the reports with his conclusions and recommendations to the Secretary of the Army for transmission to the Congress; (b) to conduct an independent review of all special reports ordered by the Congress and report thereon in the same manner as for survey reports when directed by the Chief of Engineers; (c) to consider and approve general plans for major modification and reconstruction of any lock, canal, canalized river or other work for the use and benefit of navigation. All functions of the former Beach Erosion Board pertaining to review of reports concerning erosion of the shores of coastal and lake Waters, and the protection of such shores, were transferred to the Board under section 3, Public Law 88- 172. An additional statutory duty was assigned the Board under the terms of the Merchant Marine Act of June 5, 1920. Under this act, the Board, in cooperation with the Maritime Administration, collects, compiles, and publishes information on characteristics of U.S. ports. Physical characteristics of the ports are the responsibility of the Corps, and administrative characteristics are the responsibility of the Maritime Administration. In addition to its statutory duties, the following duties are the more significant among those assigned by the Chief of Engineers: review Corps policies and procedures as directed; review reports of other Federal agencies pertaining to water resources development; conduct investigations and studies of economics of ports and waterways; and conduct a year-long program of in-service training for planners at GS-12 and GS-13 levels in all aspects of Federal water re- (rotative basis) from continental U.S. divisions. The seventh officer is assigned full time as Resident Member and directs the staff. Appointments are made by the Chief of Engineers for unspecified periods. The Board meets on call of the Chairman. sources development to assist in meeting the needs of the Corps for increased numbers of qualified personnel in this field. Also, the Resident Member is alternate for the Secretary of the Army on the Foreign- Trade Zones Board, first alternate for the Chief of Engineers on the National Capital Planning Commission, and ex-officio secretary of the American Section, Permanent International Association of Navigation Congresses, a quasi-official organization. (See separate section on PIANC). On June 30, 1969, the Board was composed of the following members: Maj. Gen. Robert G. MacDonnell, President, Mississippi River Commission (was Deputy Chief of Engineers until December 1, 1966), Chairman; Maj. Gen. Frederick J. Clarke, Deputy Chief of Engineers; Maj. Gen. Thomas J. Hayes III, Division Engineer, U. S. Army Engineer Division, South Atlantic; Brig. Gen. C.Craig Cannon, Division Engineer, U. S. Army Engineer Division, Missouri River; Brig. Gen. William M. Glasgow, Jr., Division Engineer, U. S. Army Engineer Division, South Pacific; Brig. Gen. Robert M. Tarbox, Division Engineer, U. S. Army Engineer Division, North Central; and Col. Alvin D. Wilder, Resident Member. In addition to the foregoing, the following officers were also assigned for various periods during the year to membership on the Board: Brig. Gen. Francis P. Koisch, Division Engineer, U. S. Army Engineer Division, North Atlantic; and Brig. Gen. Elmer P. Yates, U. S. Army Engineer Division, North Pacific. A summary of investigations authorized by the Congress from establishment of the Board in 1902 to the end of fiscal year 1969, the number of authorizations completed, the number of authorizations remaining to be reported on, and the number of reports submitted under continuing authorizations are set forth in table 41-A underBoad of Engineers for Rivers and Harbors. From 1902 through June 30, 1969, the Board took final action on 7,961 reports, recommending favorably on 3,526 and unfavorably on 4,435. By Public * All other tables are referenced in text and also appear ,at the end of this chapter. 1249 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Law 85-500, Congress eliminated preliminary examinations. During fiscal year 1969, the Board held five meetings of 1 to 2 days' duration in Washington. No public hearings were held. The Board considered 46 reports, acted favorably on 20, unfavorably on 17, deferred action on 2, and returned 7. The Board recommended construction of projects totaling $537,761,- 000, of which $502,694,500 was the estimated U. S. cost and $35,066,500 the cost to local interests for work and cash contributions. Of the 17 unfavorable reports acted on by the Board, 3 involved construction costs estimated at $2,683,000 consisting of $2,012,- 000 Federal, and $671,000 non-Federal. The remaining 14 reports contained no cost estimates as they dealt with improvements that were obviously unfavorable or no longer necessary. The Board's staff submitted reports or comments on reports as follows: Eight reports by other Federal agencies on water resources development; 47 reports prepared under special, continuing authorities for beach erosion control, small flood control and small navigation construction projects; and 21 special reports on civil works planning, including the review and submission of comments on revisions to procedures published or to be published in Engineer Regulations. Studies prescribed by various River and Harbor Acts and Section 8, Merchant Marine Act of 1920, continued, and the results were published in the series of reports titled 'Port Series' (See Table 41-B). 1250 BOARD OF ENGINEERS FOR RIVERS AND HARBORS BOARD OF ENGINEERS FOR RIVERS AND HARBORS Authorities Received Prior to July 1, 1968 Authorities Received During Fiscal Year Authorities Completed Prior to July 1, 1968 Authorities Completed During Fiscal Year Authorities Remaining to be Reported on Flood Control and River and Harbor Acts, Exclusive of 1909 River and Harbor Act River and Harbor Act of 1909- Continuing Authority for Major Modification Congressional Resolutions Exclusive of Great Lakes Harbors Congressional Resolutions Multiple Great Lakes Harbors Studies PL 71-84-1 Authority for Multiple Hurricane Studies River and Harbor Act, July 3, 1930 (PL 520-71), Cooperative Beach Erosion Studies Total 5,167 4,323 2 9,495 13 4,848 71 3,054 84 7,904 1251 TABLE 41-A.

Rock Island District: Mississippi River (sec. 6) levees from upper limits of St. Louis District to Rock Island, Ill. (1,437 miles AHP). MISSISSIPPI RIVER AND ALLUVIAL VALLEY BELOW CAPE GIRARDEAU, MO. Location and description. Mississippi River rises in Lake Itasca, Minn., and flows generally southerly for 2,340 miles through central portion of United States to empty into Gulf of Mexico about 115 miles below New Orleans. It is improved for barge navigation for about 1,832 miles to Minneapolis, Minn. The Mississippi River and its major tributaries, the Missouri, Ohio, St. Francis, White, Arkansas, Yazoo, and Red- Old Rivers, drain 1,245,000 square miles in all or part of 31 States between the Rocky and Appalachian Mountains and part of two Canadian Provinces. Below Cape Girardeau, Mo., 53 miles above Ohio River, river bottom lands widen abruptly into an alluvial valley of about 35,460 square miles which was originally subject to flood overflow. A major part of alluvial valley has been protected from floods by levees which confine floodflows within a flood plain having an average width of about 5 miles. (See map of alluvial valley of Mississippi River, scale 1:500,000.) Observations made by Mississippi River Commission to June 30, 1969, show approximate maximum and minimum discharges between levees as follows: Cairo' to White River, 2,000,000 and 70,000 cubic feet per second; thence to Red River, 2,150,000 and 90,000 cubic feet per second; thence to the Gulf of Mexico, 1,500,000 and 80,000 cubic feet per second in Mississippi River and about 660,000 and 11,000 cubic feet per second in Atchafalaya River. As 1927 floodflow was not confined between levees, maximum discharges recorded do not include entire flow of 1927 flood, maximum of record below White River. High water and flood stages usually occur in late winter or early spring, but great floods such as that of 1937 occurred as early as January. Low water stages generally prevail from August to December. Extreme ranges in stages recorded at representative gages are about 60 feet at Cairo, 55 feet at Memphis, 58 feet at Red River Landing, and 23 feet at New Orleans (Carrollton). River is nontidal above Red River Landing where tidal amplitude rarely exceeds 0.1 foot during extreme low water. Previous projects. For details see page 1944, Annual Report for 1932, and page 1682, Annual Report for 1937. Existing project. For the Mississippi River and tributaries in alluvial valley between Head of Passes, La., and Cape Girardeau, Mo., provides for protection thereof from floods by means of levees, floodwalls, floodways, reservoirs (in Yazoo and St. Francis Basins), bank stabilization, and channel improvements in and along the river and its tributaries and outlets insofar as affected by backwater of Mississippi River, including levee work on main stem between Cape Girardeau and Rock Island. When completed, 23,621 square miles will be protected from theMississippi River project flood. Project also provides for a 12- by 300- foot navigation channel between Baton Rouge, 1254 MISSISSIPPI RIVER COMMISSION La., and Cairo, Ill.; for salinity control structures; and for channel realinement and improvement including bank stabilization and dikes to reduce flood heights, control natural tendency of river to lengthen by meandering, and protect levees from being destroyed by caving banks. Locations of major Mississippi River project improvements for flood control and navigation, including main stem levees and appurtenant drainage structures and spillways, channel realinenient and dredging, bank revetment, and dikes are Shown in table 42-A. Construction of existing project began in 1928 and has continued throughout ensuing Years. Based on the estimated cost of $2,705,871,300 (July 1, 1969 price levels) and actual expenditures through June 30, 1969 of $1,576,508,800, the entire project is about 58 percent complete. Locations of levee work done under provisions of section 6, Flood Control Act of 1928, are shown in table 42-N. Project provides for harbor improvements on main stem at Baton Rouge (Devils Swamp), La., Vicksburg, Miss., Greenville, Miss., and Memphis, Tenn. Locations of these improvements on tributaries and outlets in designated basins are listed in table 42-B. Table 42-C contains data pertinent to dams and reservoirs. (See above-mentioned tables at end of chapter.) (See also tables 42-D and 42-E for authorizing legislation.) Recommended modifications. None. Local cooperation. The Flood Control Act of 1928, as amended, applies. Such requirements have, in general, been complied with by local interests. Terminal facilities.

Project cost. Total monetary authorizations, including the modifications to June 30, 1969, are $1,684,- 922,600. Total allotted for flood control, including maintenance charges through August 18, 1941, chargeable under authorizations to June 30, 1969, Was $1,587,298,100. (See table 42-S.). (See also table 42-F on summary of presently estimated first cost of authorized improvements.) Operations and results during fiscal year. Commis- Sion activities: The 278th session was held, October 7-12, 1968, on board the U. S. MV Mississippi en route on the Mississippi River from Cape Girardeau, Mo., to Old River, La., on Old River to the Atchafalaya River, and on the Atchafalaya River to Morgan City, La. The 279th session was held, April 28-May 3, 1969, on board the U. S. MV Mississippi en route on the Mississippi River from Cairo, Ill., to the Head of Passes, La. On these river trips, major features of the project were inspected, including bank protection works, contraction works, levees, and general channel conditions, to the extent permitted by river stages. Public hearings were held, at which representatives of local governmental agencies, navigation, levee, commercial, and other interests presented problems pertaining to flood control and navigation. During the 278th session, some members of the Commission inspected the East Atchafalaya guide levee from Krotz Springs to Morgan City, La The President, Mississippi River Commission, and his engineering assistants made periodic inspections of flood control, navigation, and related works tinder the existing project along the Mississippi River and tributaries in the alluvial valley from Cape Girardeau, Mo., to the Gulf of Mexico. District Engineers held flood-fight planning conferences with local interests. A favorable review report, 'Eastern Rapides and South-Central Avoyelles Parishes, Louisiana,' dated July 19, 1968, was forwarded to the Chief of Engineers. The favorable report, 'Yazoo River (Lower Tributaries), Mississippi - Interim Report on Steele Bayou Basin,' dated April 30, 1969, was forwarded to the Chief of Engineers. A favorable review report, 'Western Tennessee Tributaries, Tennessee and Kentucky,' dated April 30, 1969, was forwarded to the Chief of Engineers. Alluvial valley mapping: Contoured quadrangles and general maps of the alluvial valley are available for departmental use and public distribution under prescribed regulations. Road-map-type information folders of principal portions of overall project were published along with papers on subject of flood control and navigation. Preparation and publication of quadrangle maps (scale 1:62,500) continued. The 1968 (36th) edition of the folio of flood control and navigation maps, scale 1:62,500, covering Mississippi River from Cairo, Ill., to Gulf of Mexico was compiled and printed. Some 10,688 flight-line miles of aerial photography (various scales) and 17 hours of oblique photography were flown along Mississippi River and tributaries and other areas in New Orleans, Vicksburg, and Memphis Districts. Work accomplished in the districts: New Orleans District Series conversions of the Belle Isle, Morgan City, Napoleonville, New Orleans, and Spanish Fort maps were completed and are now ready for printing. 1255 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Work was initiated on the Bonnet Carre, Chef Menteur, Covington, Hahnville, Ponchatoula, Rigolets, St. Bernard, and Yscloskey maps. New Orleans and Baton Rouge maps, scale 1:250,000, were revised and printing completed. Surveying, mapping, and scribing of hydrographic and topographic maps of Red River are in progress.

Surveys, gages, and observations: Routine hydrographic surveys, construction surveys, and special surveys and inspections were made as required. Gages were maintained and discharge observations made. Results thereof are presented in detail in annual pamphlets issued by the districts. Floods: Memphis District - Mississippi River crest stage of 47.27 feet at Cairo gage and maximum discharge of 1,135,000 cubic feet per second occurred on Feb. '12, 1969, due to moderate to heavy rains that fell, during the week of Jan. 27 to Feb. 2, from northeastern Texas to the Ohio River Valley and spread over the rest of the east by the weekend. Totals from southwestern to northeastern Arkansas ranged from 6 to 8 inches. Considerable flooding occurred in Arkansas and the Ohio River Valley. Vicksburg District - Stages on the Mississippi River were about normal with minor fluctuations during the year. Principal rises occurred in February and the latter part of April and early May. Stages on the Ouachita River were low from July through November 1968. Heavy rains occurred during January, producing unusually high stages on tributaries in the upper Ouachita River Basin. The crest stage occurred at Arkadelphia on January 31 at 28.0 feet, 11 feet above flood stage. The river crested at Camden on February 3, at 39.2 feet, about 13 feet above flood stage. Relatively high stages occurred on the Saline and Caddo Rivers. The Black River at Jonesville was moderately high from February through May, cresting about 3 1/2 feet below bankfull in March. Flood control works reduced crest stages about 4 feet at Arkadelphia and about 2 feet at Camden. Stages on Tensas River were well below bankfull throughout the year. Stages on the Coldwater-Tallahatchie-Yazoo Rivers were moderately high, December through May 1969. Principal rises were in December, February, and April. The crest stage at Swan Lake occurred in February and was 1.4 feet above flood stage. Operation of flood control works effected reductions averaging about 5 feet on the Coldwater and Tallahatchie Rivers, about 10 feet at Greenwood, and 6 feetat Yazoo City. The major rise on the Big Black River occurred in April when crest stages were 5 to 11 feet above bankfull. New Orleans District - No flood stages were recorded in the lower Mississippi and Red River Basins. Investigations and reports: Surveys and reports prescribed under existing project, and called for by congressional or departmental directives, were made as required. Memphis District expended $27,122 on one navigation study, $242,117 on seven flood control studies, and $40,111 on collection and study of basic data. Vicksburg District expended $45,523 on one navigation study, $251,088 on four flood control studies, and $60,486 on collection and study of basic data. New Orleans District expended $33,289 on four flood control studies. Surveys were made and gages operated and maintained. In addition, $311,556 was expended on the West Texas and Eastern New Mexico Water Import Study to determine the advisability of improvements for exporting, by the most feasible means, surplus water, if any, in the Mississippi River system to water-deficient areas. This investigation is being made in cooperation with the Bureau of Reclamation in its current reconnaissance studies of measures for importing water into west Texas and eastern New Mexico. The Southwestern Division, Corps of Engineers, will make studies for that portion of the area within its boundaries. MISSISSIPPI RIVER--LEVEES Operations and results during fiscal year. Enlargement of dikes and restoration of eroded portions of existing levees; enlargement of existing levees to approved grade and section, 10.4 miles in New Orleans 1256 MISSISSIPPI RIVER COMMISSION District, and 4.2 miles in Memphis District; construction of levee berms, 7.3 miles in Vicksburg District, and 3.4 miles in Memphis District; surfacing material placed on 15.4 miles of levee roads in Memphis District; and construction of 1.7 miles of new levee wave- Wash protection along the lower Mississippi River below Baton Rouge. Restoration of damaged wavewash and foreshore protection was accomplished as required. For further details see tables 42-K, 42-L, and 42-M. Condition at end offiscalyear. There are 1,597 miles of levee now authorized for the Mississippi River below Cape Girardeau, of which 1,565 are in place with 1,390 built to approved grade and section. (Above figures include 72 miles on completed separable features.) The Main Stem Levee System consisting of 2,192 miles, of which 1,870 have been completed, includes additional levees and structures along the south bank of Arkansas River (85.4 miles); along the south bank of Red River (59.8 miles, with 51.6 completed); and 449.2 miles in the Atchafalaya River Basin, with 343.1 completed. Graveled or hard-surfaced roads have been constructed on 970 miles of these levees. (Tables 42-K, 42-L, and 42-M.) Below Baton Rouge, in New Orleans District, about 136 miles of levee are protected against river wavewash by timber structures or levee-slope pavement. Foreshore protection works extend along 92 miles of levee. In order to insure adequacy of main stem levees, including those on south banks of Arkansas and Red Rivers, additional levee construction is recommended to provide a standard 3-foot freeboard, adequate levee cross section, construction of berms for levee stabilization and seepage Control, levee wavewash protection where necessary, drainage structures, and roadways for proper inspection and maintenance. Status of levees authorized under provisions of section 6, 1928 act is summarized in table 42-N. MISSISSIPPI RIVER-.CHANNEL IMPROVEMENTS Operations and results during fiscal year. Engineering studies: Continued a research program for development of materials and more effective and economical procedures for placing and stabilizing Mississippi River in a suitable alinement. Bank revetment and dikes: Construction of 9.1 miles of new bank revetment and 3.0 miles of reinforcement of existing revetment was completed by Government plant and hired labor, and construction of 14.1 miles of new dikes and reinforcement of 0.4 mile of existing dikes were completed by contract. Further data concerning this work are shown by districts in tables 42-H, 42-I, and 42-J. Dredging: Work included dredging 45,946,000 cubic yards for channel and harbor maintenance and channel construction and revetment. Minimum channel depth of 9 feet was maintained. Dredging shown in table 42-G was done with the following plant: New Orleans District, two contract cutterhead dredges and one Government-owned dustpan dredge (on loan); Vicksburg District, one Government-owned dustpan dredge and one leased cutterhead dredge; and Memphis District, three Government-owned dustpan dredges and two leased cutterhead dredges. (See also tables 42-0, 42-P, and 42-Q). Other work performed in interest of navigation, supplementing maintenance dredging on Mississippi River between Cairo, Ill., and Baton Rouge, La., included removal of snags, wrecks and obstructions; weekly channel patrols during low water season and periodic channel patrols during high water season; issuance of navigation bulletins by the Coast Guard, Memphis, Vicksburg, and New Orleans Districts, providing steering directions, information on available channel depths and high-water velocities at selected locations; buoyage of crossings during low water for Coast Guard on a reimbursable basis; (on May 1, 1966, the Coast Guard assumed buoyage work between Cairo and Memphis (miles 953.8-735.0) and from Vicksburg to Artonish Light (miles 435.8- 322.5); placing and maintaining dike and high water buoys during the high water season; maintaining bulletin boards showing daily gage readings at regular MRC gages; and contact pilot service furnishing navigation with latest information and advice on channel conditions and obtaining their views as to needs of navigation interests. Cost of this work is given in table 42-R. Condition at end of fiscal year. In carrying out authorized channel improvement program between Baton Rouge and Cairo, 16 cutoffs were developed between 1933 and 1942. These, combined with chute channel development and alinement improvements, decreased channel length between these cities by about 180.miles. Effect of this channel shortening, in increasing its flood-carrying capacity, is stated on page 1811, Annual Report for 1943. Much progress has been made in advancing overall channel stabilization program, involving construction of bank revetment, dikes, and improvement dredging, to prevent river from regaining its former length due to its natu- 1257 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 ral tendency to meander. There are now in place 596 miles of operative bank.revetment and 103 miles of dikes on Mississippi and lower Ohio Rivers as listed on tables 42-H, 42-I, and 42-J. A navigation channel 9 by 300 feet is maintained by dredging as required during low-water season. Due to growing effectiveness of channel improvement program, average maintenance dredging requirements are steadily being reduced, and an increase in navigable depth is being obtained. A long-range plan has been developed and recommended to bring about desired program of channel improvement between Cairo and Head of Passes including additional bank revetment, dredging, contraction works, and foreshore protection. ATCHAFALAYA BASIN, LA. Operations and results duringfiscal year. New work by hired labor: Real estate activities and planning for construction were continued.

U.S. Army Coastal Engineering Research Center was established under authority of Public Law 172, 88th Congress, which abolished the former Beach Erosion Board (organized under authority of sec. 2, 1930 River and Harbor Act), as amended (33 USC 426) and directed that its functions o ther than review of reports of investigations made concerning erosion and protection of shores of coastal and lake waters, be vested with Coastal Engineering Research Center. The report review function Was transferred to Board of Engineers for Rivers and Harbors, putting reports on beach erosion control and shore protection studies under the same review procedures as reports in other phases of the water resources study program of the Corps. The authorizing act also provided that the functions of Coastal Engineering Research Center be conducted with guidance and ad- Vice of a Coastal Engineering Research Board, to be COnstituted by the Chief of Engineers in the same manner as the former Beach Erosion Board. During Fiscal Year 1969 the following served as members of Coastal Engineering Research Board: rig. Gen. Charles C. Noble, U. S. Army and Brig. Gen. Francis P. Koisch, U. S. Army, President; Maj. Gen. Charles M. Duke, U. S. Army, Division Engineer, North Atlantic Division; Maj. Gen. Thomas J. Hayes III, U. S. Army, Division Engineer, South Atantic Division; Brig. Gen. William M. Glasgow, Jr., ., S. Army, Division Engineer, South Pacific Divi- Sion; Dr. Thorndike Saville, Consulting Engineer to the State of New York; Dean Morrough P. O'Brien, bean Emeritus of College of Engineering, University of California; Dr. Arthur T. Ippen, Professor of Hydraulics, Massachusetts Institute of Technology, and Dr. Robert G. Dean, Chairman of the Department of Coastal and Oceanographic Engineering, University of Florida. Lt. Colonel Myron Dow Snoke was Executive Secretary to the Board and Director of the Center. The Coastal Engineering Research Center is the Principal research and development facility of the Corps in the field of coastal engineering. Its general functions are: (a) conceive, plan, and conduct research and development to provide better understanding of shore processes, winds. waves, tides, surges, and currents as they apply to navigation improvements, flood and storm protection, beach erosion control, and Coastal engineering works; (b) furnish technical assistance as directed by the Chief of Engineers in the conduct of studies made by other elements of the Corps with the view of devising effective means of Preventing erosion of shores of coastal and lake waters by waves and currents; and (c) publish information and data concerning coastal phenomena and research and development projects which are useful to the Corps and the public. Other functions assigned by the Chief of Engineers are: (a) assist the Chief of Engineers in planning and designing coastal works, including determination of probable effects of such works on adjacent shore lines, establishment of hurricane protection criteria, evaluation of effectiveness of proposed coastal navigation improvements; and in review for technical adequacy of studies, plans and specifications for beach erosion control and other coastal engineering works; (b) provide staff support to Coastal Engineering Research Board in conduct of its functions; (c) maintain liaison through appropriate Army and governmental agencies with domestic and foreign institutions which have the same interests in order to evaluate the effect of other efforts on the U.S. coastal research program; and (d) provide consulting services on coastal engineering problems to other elements of the Corps and other governmental agencies as directed. Operations and results during fiscal year. Staff of Coastal Engineering Research Center reviewed 30 reports for technical adequacy, of which 12 were navigation, 13 beach erosion control, one flood control, and 3 combined beach erosion control-hurricane reports. An additional 3000-copy printing of Technical Report No. 4 'Shore Protection, Planning and Design' was ordered, and about 2700 copies are currently available through U. S. Government Printing Office. In keeping with the responsibility for publishing information and data concerning coastal phenomena, 14 technical reports' by staff members were published by CERC or in other technical journals during the year and 6 others are currently in press; 3 abstracts were published in technical journals, and 1 is in press. Three Technical Memorandums were issued by Coastal Engineering Research Center, 1 is in press and 7 more are in preparation to go to press. Three technical manuscripts were published in the 'Miscellaneous Papers' series. Ten additional reports are in preparation. The staff worked on ten major research or engineering projects for various agencies and prepared 6 repots thereon. A number of lesser studies were made and reported on. A training course in coastal engineering was given to a group of trainees from the Board of Engineers for Rivers and Harbors, invited lectures were given at four universities, and a number of descriptive presentations were made by staff members to technical and non-technical groups. Members of the staff participated in a number of committees and panels of the National Council on 1293 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Marine Resources and Engineering Development, and various technical societies. Plans for the eventual relocation of CERC to Fort Belvoir, Va. with expanded facilities were developed, submitted to, and approved. Research to supplement staff activities was carried out at 16 universities under 25 contracts, and with 9 commercial concerns. Funds were also provided the Waterways Experiment Station to assist in construction of the generalized tidal model basins and initiate work on mathematical modelling of harbor oscillation and underwater soil mechanics, and to the Sandy Hook Marine Laboratory for study on effects of offshore dumping. The basic structure for a prototype experimental groin at Pt. Mugu. California was completed. At the end of the year, studies by the staff were in progress on: characteristics of ocean waves by actual measurement at a number of localities; development of new types of wave gages; methods of bypassing sand at inlets; sources of beach material; propagation and effect of secondary waves; relation of littoral drift rate to incident waves; amount of suspended sand in the surf zone; model-scale effects; adaptations of the wave spectrum analyzer to laboratory and full field use; methods of analyzing waves, and their relative meanings; use of radioactive and fluorescent tracers in beach studies; sand dune growth and stabilization by sand fences and vegetation; beach deformation under wave action; use of offshore borrow material for beach fills; test of riprap protection for earth dams; reexamination of completed shore protection projects; corrosion and life of steel piles; effect of groins; estuarine erosion; use of synthetics in coastal structures; air-sea interaction; accumulation of material on geomorphology, littoral materials, and beach characteristics of various areas; use of middle-ground shoal area as deposition trap in sand bypassing; and the ecological effects resulting from engineering projects in the coastal zone. Research work at the Coastal Engineering Research Center or sponsored at universities is, in general, fi" nanced by Coastal Engineering Research and Development funds, General Expense Funds, and Engineering Studies funds. Appropriated and allotted funds in the three categories for fiscal year 1969 amounted to $2,800,000, $222,000 and $57,000, respectively, a total of $3,079,000. Reimbursable projects provided other funds amounting to about $100, 000 for inhouse use. 1294 CALIFORNIA DEBRIS COMMISSION* This Commission, consisting of three Corps officers appointed by the President with the consent of the Senate, created by act of March 1, 1893 (27 Stat. L., p. 507), was organized in San Francisco, Calif., on June 8, 1893, and has jurisdiction and duties extending Over drainage area of Sacramento and San Joaquin Rivers, comprising great central valley of California and extending from crest of Sierra Nevada on the east to that of Coast Range on the west, and from Mount Shasta and Pitt River Basin on the north to Tehachapi Mountains on the south. These rivers empty into head of Suisun Bay ultimately discharging into Pacific Ocean through connecting bays and straits and the Golden Gate. Duties of the Commission comprise regulation of hydraulic mining in drainage area of Sacramento and San Joaquin Rivers, Calif., so that debris will not be carried into navigable waters or otherwise cause damage; jurisdiction over construction and control of water storage facilities for domestic, irrigation and power development purposes; and direction of improvements for control of floods on Sacramento River.

Condition at end of fiscal year. The Commission received 1,292 applications for hydraulic mining licenses; 3 mines are licensed, none of which use storage behind Government debris dams. Work remaining is, in general, continuation of above or similar operations. 2. SACRAMENTO RIVER AND TRIBUTARIES, CALIFORNIA (DEBRIS CONTROL) Location. Project reservoirs are to be constructed in watersheds of Yuba, Bear, and American Rivers, Calif. (See Geological Survey sheets for basin areas, seven in number.) Existing project. Designed to permit resumption of hydraulic mining on a substantial scale and provides for construction of reservoirs for purpose of retaining mining debris. North Fork Reservoir is on North Fork of American River about 5 miles northeast of city of Auburn and 40 miles northeast of Sacramento. Dam is 155 feet high, 620 feet long, and reservoir has a debris-storage capacity of 26 million cubic yards. Harry L. Englebright Reservoir is on Yuba River about 20 miles northeast of city of Marysville. Dam is 280 feet high, 1,142 feet long, and reservoir has a debris storage capacity of 118 million cubic yards. Completed reservoirs are also utilized for recreation purposes; initial facilities were provided in fiscal year 1959. Recreation areas at Harry L. Englebright Reservoir are maintained by the Corps. Recreation areas at North Fork Reservoir are maintained and operated by Auburn Recreation Park and Parkway District. Total Federal cost of new work for construction of these reservoirs was $4,646,872, including $40,000 for recreation facilities. Cost of recreation areas at North Fork Dam was $57,500. It is estimated (July 1969) that improvements to recreation areas will cost $1,173,000 for Harry L. Englebright Dam. Reservoir project sites on Middle Fork of American River and on Bear River are considered inactive and excluded from foregoing cost estimate. Estimated cost of this portion is $1,820,000 (1935). Existing project was adopted by River and Harbor Act of 1935 (Rivers and Harbors Committee Doc. 50, 74th Cong., Ist sess.). For latest published map, see project document. Act of November 6, 1945, provided that dam constructed at Upper Narrows site on Yuba River, Calif., should thereafter be Harry L. Englebright Dam. Local cooperation. Satisfactory assurances were furnished the Secretary of the Army for repayment of capital cost of reservoir from taxes on material hydraulically mined, under licenses, and impounded in these reservoirs. These funds are paid to Director of Internal Revenue then credited by Treasurer of the United States to Hydraulic Mining in California Debris fund. Improvements made to facilities at North Fork Dam and Reservoir by Auburn Recreation Park and Parkway District under a lease agreement with Secretary of the Army and Auburn Boat Clubs (concessionaire) at an estimated cost of $36,000 since September 1953. Licenses. Under provisions of Contract No. W-1105-eng-2998 with Pacific Gas and Electric Co., payment is to be made to the Federal Government of $18,000 per year for the first 30 years (December 29, 1942-1972) and $48,000 per year between December 29, 1972, and December 29, 1992, in return for use of head at Englebright Dam and generation of hydroelectric power. Total payment through June 30, 1969, amounts to $468,100; these funds are paid to California Debris Commission and deposited for credit by Director of Internal Revenue to 'Debris Fund.' Operations and results during fiscal year. New work: Englebright Reservoir, Code 710 funds--Engineering continued. Condition at end of fiscal year. Construction of darns was initiated in 1937; North Fork Dam and Reservoir was completed and in use at end of fiscal year 1939; and Harry L. Englebright Dam and Reservoir was completed in January 1941. The two debris-conf trol structures are in good condition. Public use of these reservoir recreation areas greatly overtaxes present capacities. 3. TREATMENT OF YUBA RIVER DEBRIS SITUATION-RESTRAINING BARRIERS, CALIFORNIA Location. Works are on Yuba River between Marysville and where the river emerges from the foothills, near Hammonton, some 10 miles easterly from Marysville, or about 9 miles below the NarroWS. (See Geological Survey Topographic map of Sacramento Valley, Calif.) Existingproject. Provides for storage of mining debris within riverbed of Yuba River, a nonnavigable stream, to keep such debris from passing into Feather and Sacramento Rivers to detriment of navigation therein. Improvement consists of a debris barrier, a 40-foot wide reinforced concrete stepped slab with upstream and downstream cutoff walls; training walls 85,100 feet long which provide a 600-foot wide chan* 1296 CALIFORNIA DEBRIS COMMISSION nel above and a 500-foot wide channel below dam; dikes across overflow channels; and protective works downstream to maintain Yuba River in its confined channel to its junction with Feather River at Marys- Ville. Total cost of new work was $723,259, of which $361,482 was U.S. funds and $361,777 required contributed funds by State of California. (For details of project in its original form, see Annual Report, 1917, P. 1810.) In February 1963, center section of dam failed and major rehabilitation of structure was completed in December 1964. Total cost for required rehabilitation was $1,660,000, of which $830,000 was Federal cost and $830,000 required contribution by State of California toward rehabilitation cost. During the December 24, 1964 floodflows on the Yuba River, the rehabilitated Daguerre Point Dam sustained considerable damage. (See 1965 Annual Report, p. 1647 'Operations and results during fiscal year'.) The re- Constructed portion of the dam completed earlier in December 1964 was undamaged by the flood. Permanent repair of Daguerre Point Dam abutment and fish facilities was completed in October 1965 at a cost of $447,808 with Federal and required State contributed funds on a matching basis. Existing project was adopted in a rather indefinite form by River and Harbor Act of 1896 and in its more definite form by River and Harbor Act of 1902 (H. Doc. 431, 56th Cong., 1st Sess.). (For latest published map, see Geological Sur- Vey topographic map of Sacramento Valley, Calif.) Local cooperation. Fully complied with for new Work and major rehabilitation work. Total first cost to local interests for new work was $361,777, all of Which was required contribution by State of California. In addition, training walls were built on each bank below Daguerre Point for 11,250 feet and just above Daguerre Point, on the south bank, for 11,000 linear feet by two gold-dredging companies in connection with their dredging operations. It was estimated (1902) that it would have cost the United States $450,000 to build these training walls. Flood channels Were also built by gold-dredging companies within the confines of the project works. It was estimated (1926) that cost of equally effective works to restrain debris movement would have been more than $776,- 000 to the United States. Total costs to local interests for initial and permanent major rehabilitation works Were $830,000 and $224,350, respectively, all of Which was required contribution by State of California. State of California must contribute annually an amount equal to the Federal allotment for maintenance. Operations and results during fiscal year. Maintenance: Operations included condition and operation studies, and preparation of plans and specifications, by hired labor. In addition, bank restoration and stone protection was accomplished, by contract, along right and left banks Yuba River, various locations upstream from Marysville. Contract cost for this work was $48,067 with Federal and required State contributed funds on a matching basis. Condition at end of fiscal year. Construction of project works was initiated in November 1902. Construction of Daguerre Point Dam was completed in May 1906; diversion of river over dam was completed in 1910; training walls and dikes were completed in 1935. About 140 million cubic yards of debris are held in lower 7 miles of Yuba River between Marysville and downstream end of training walls. About 20 million cubic yards are confined in river channel by Daguerre Point Dam. Additional millions of yards of loose material are.in mine tailings fields adjacent to project training walls in upper 7-mile reach of project. Initial rehabilitation of Daguerre Point Dam, begun in July 1963, was completed in December 1964. Contract for permanent rehabilitation of structure was initiated in July and completed in October 1965. Flood Control 4. SACRAMENTO RIVER, CALIF. Location. Works covered by this improvement are on Sacramento River andtributaries in north-central California from Collinsville to Ord Bend, a distance of 184 miles. Previous project. For details see page 1815 of Annual Report for 1917, page 1995 of Annual Report for 1938, and page 2262 of Annual Report for 1907. Existing project. Sacramento River flood control project is a comprehensive plan of flood control for Sacramento River and lower reaches of its principal tributaries. Improvement extends along Sacramento River from Ord Bend in Glenn County, Calif., 184 miles downstream to its mouth at Collinsville at upper end of Suisun Bay, and comprises a system of levees, overflow weirs, drainage pumping plants, and flood bypass channels or floodways designed to carry surplus floodwaters without inundation of valley lands. About 980 miles of levee construction with an average height of 15 feet, and 98 miles of ban': protection are involved in project. For further details, see Annual Report for 1962, page 2115. (See table 44-B for authorizing legislation.) 1297 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 Approved estimated (July 1969) cost for existing project (exclusive of above supplemental levee improvements), including new work and maintenance, is $163,630,000, of which $68,630,000 is Federal cost and $95 million non-Federal ($90,050,562 for lands and damages and relocations and $4,949,438 required contributed funds for levee construction, bank-protection works, and levee setbacks). Of this amount $4,939,752 was for new work and $9,686 for maintenance. In addition to project requirements, local interests constructed several pumping plants for drainage of agricultural and urban land protected by project levees. Also, some channel-clearing work was accomplished by State of California and other local interests to supplement project levee construction. Dredging below Cache Slough and reconstruction of Cache Creek settling basin weir are considered deferred and excluded from foregoing cost estimate. Estimated cost (July 1962) of these project units is $2,- 560,000 and $520,000, respectively, a total of $3,- 080,000, plus U.S. costs, for construction. Operation and maintenance of completed project will be responsibility of local interests; as units of project are completed they are transferred to agencies of State of California for operation and maintenance. Existing project was adopted by 1917 Flood Control Act (H. Doc. 81, 62d Cong., 1st sess., as modified by Rivers and Harbors Committee Doc. 5, 63d Cong., 1st sess.), and modified by 1928 Flood Control Act (S. Doc. 23, 69th Cong., 1st sess.), River and Harbor Act of 1937 (S. Committee print 75th Cong., 1st sess.), and 1941 Flood Control Act (H. Doc. 205, 77th Cong., 1st sess.). Local cooperation. Local interests have fully complied with requirements for all work completed or under contract, and indicated they will be able to fulfill requirements for remainingwork as scheduled. Local interests' costs from required contributed funds for project work total $4,949,438 for levee construction, bank-protection works, and levee setbacks, of which $4,939,752 was for new work and $9,686 for maintenance. Operations and results during fiscal year. Regular funds: Engineering continued. Project prevented an estimated $12,000,000 in damages from the January- February 1969 floods. Condition at end offiscalyear. Construction of existing project began in fiscal year 1918 and is about 99 percent complete. Channel improvement to date has produced a channel with a capacity of 579,000 cubic feet per second in Sacramento River below Cache Slough. In addition, discharges up to 21,000 cubic feet per second can be diverted from Sacramento River through Georgiana Slough. Completed major project items include about 977 miles of levees; five weirs with a combined discharge capacity of 602,000 cubic feet per second; two cutoff channels; two sets of outfall gates; channel improvement and clearing in Sacramento River, Butte Creek, Putah Creek, and Sutter and Tisdale Bypasses; construction of two main bypasses or floodways and secondary bypasses at Tisdale and Sacramento weirs and at Wadsworth Canal; construction of Knights Landing ridge cut and of Cache Creek settling basin; installation of gaging stations; and enlargement of Sacramento River below Cache Slough. Cutoffs at Collins Eddy and between Wild Irishman and Kinneys Bends were made in 1918 and 1919, respectively. Sacramento weir was completed in 1917, Fremont weir in 1924, Tisdale and Moulton weirs in 1932, and Colusa weir in 1933. Outfall gates at Knights Landing were constructed in 1930 and at mouth of Butte Slough in 1936. Pumping plants on Sutter Bypass were completed in 1944. Work items with reference to clearing, snagging, rectification of channels, and bank protection on Sacramento River and tributaries in Tehama County and from Red Bluff southerly, provided for by 1941 Flood Control Act were accomplished in fiscal years 1947, 1948, 1949, and 1951. Work remaining comprises completion of levee stage construction, Yolo Bypass and Cache Slough. (See table 44-C for total cost of existing project to June 30, 1968.)

REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 AUTHORIZING LEGISLATION Acts Work Authorized Documents 1. Regulation of Hydraulic Mining and Preparation of Plans 4. Sacramento River, Calif. Mar. 1, 1893 Created California Debris Commission and authorized: (a) Hydraulic mining under its regulation in drainage areas of Sacramento and San Joaquin Rivers, if possible without injury to navigability of these river systems or to lands adjacent thereto; and (b) Preparation of plans by Commission for improvement of navigability of these river systems, and flood and debriscontrol therein. Feb. 27, 1907 Authorized California Debris Commission to permit hydraulic mining without construction of impounding works, provided there is no injury to navigability of above river systems or lands adjacent thereto. June 19, 1934 Amended Act of Mar. 1, 1893, which provides for construction of debris dams or other restraining works by California Debris Commission and collection of a 3- percent tax on gross proceeds of each mine using such facilities, so as to eliminate this tax and substitute an annual tax per cubic yard mined, obtained by dividing total capital cost of each dam, reservoir, and rights-ofway, by total capacity of reservoir for restraint of debris; and authorized revocation of Commission orders permitting such mining, for failure to pay this annual tax within 30 days after its due date; and also authorized receipt of money advances, from mineowners to aid such construction, to be refunded later from annual payments of yardage taxes on material mined. June 25, 1938 Added at end of Sec. 23 of above Act, a provision that Secretary of the Army is authorized to enter into contracts to supply storage for water and use of outlet facilities from debris-storage reservoirs for domestic and irrigation purposes and power development, upon such conditions of delivery, use, and payment as he may approve, these payments are to be deposited to credit of such reservoir project, reducing its capital cost to be repaid by tax on mining operations Dec. 22, 1944 Additional levee construction and reconstruction, inand May 17, cluding levee protection of Upper Butte Basin, and 1950 multipurpose reservoirs. 2 July 3, 1958 Bank protection and incidental channel improvements, Sacramento River from Chico Landing to Red Bluff, and local interests flood-plain zoning above Chico Landing.2 July 14, 1960 Bank protection works at critical locations, Sacramento River.

The Chief of Engineers, by letter dated June 18, 1929, to the President of the Mississippi River Commission, directed establishment of an hydraulic laboratory in the alluvial Valley of the Mississippi. This institution is the Water- Ways Experiment Station with installations at Vicksburg and Jackson, Miss. It was initially established in 1929, under jurisdiction of President, Mississippi River Commission. By General Order 9, Office, Chief of Engineers, July 29, 1949, the station was transferred to direct jurisdiction of Chief of Engineers, effective August 10, 1949. Colonel Levi A. Brown, Corps of Engineers, is director. The organization is the principal field agency of the Corps for the conduct of scientific and engineering research, development, and investigational activities in technical fields of hydraulics, ground mobility, flexible pavements, soils other than those phases involving seasonal frost and permafrost, nuclear and con- Ventional weapons effects on structures, terrain and Waterways, and concrete other than those phases directly relating to design. and construction of rigid pavements. On a reimbursable basis, Waterways Experiment Station performs experimental studies and applied research, and provides consulting services pertaining to problems encountered throughout the Corps as are within its broad capabilities in its as- Signed fields. Such services include model and prototype studies, engineering and analytical design studies including blast and shock effects, laboratory research concerning portland cement and bituminous concrete mixture proportioning, laboratory testing, and field Investigations. Field investigation services include planning, accomplishment, and analysis of: comprehensive exploration of soil and rock formations; comprehensive examination and inspection of portland- Cement concrete structures in service, including use of nondestructive testing procedures; instrumentation Systems to measure water velocities and directions and to determine pressures, deflections, and strains in engineering structures; telemetry systems, principally for hydrologic data; and field inspection services, including establishment of control laboratories and training field personnel. Subject to approval by Chief of Engineers, studies can also be undertaken for other agencies. Waterways Experiment Station also operates for the Corps a central agency for analysis and dissemination of technical information, particularly in, but not necessarily limited to, fields covered by Hydraulics, Soils, and Concrete Divisions. In connection with this fact-disseminating service, the station maintains an extensive scientific and engineering reference library and issues publications of general interest, which can aid materially in eliminating duplication of effort throughout the Corps in the conduct of experimental studies. During Fiscal Year 1969, two annual summaries, 173 reports of individual studies conducted at Waterways Experiment Station, 10 translations, 14 contract reports, and 25 miscellaneous publications for Waterways Experiment Station and other offices were distributed to Corps offices and interested outside agencies. In addition, editing and printing units completed about 2,400 miscellaneous assignments for Waterways Experiment Station and other offices. Operations and Results During Fiscal Year. Work accomplished at Waterways Experiment Station is, in general, initially financed by a revolving fund, reimbursement being obtained directly from agencies for whom work is performed. Cost for operation of station for fiscal year 1969 was $20,308,904, of which $18,192,411 was charged to establishments served for research investigations and related services, and $2,- 116,493 for permanent improvements and equipment. Of the reimbursable work, $5,847,729 was charged to civil funds, $12,232,270 to military funds, and $112, 412 to nongovernmental agencies. work includes $1,439,204 performed by contract. Total cost incurred for operation of Waterways Experiment Station to June 30, 1969, was $242,304,349, of which $227,427,461 represents reimbursable cost and $14,- 876,888 the unamortized cost of permanent improvements and equipment. 1303 PERMANENT INTERNATIONAL ASSOCIATION OF NAVIGATION CONGRESSES The United States by act of June 28, 1902, appropriated $3,000 a year for support and maintenance of the Permanent International Commission of Navigation Congresses and for payment of the actual expenses of properly accredited national delegates of the United States to meetings of the Congresses and Commission. An increase in the appropriation of $5,- 000 annually was authorized by 1948 River and Harbor Act. The 1965 River and Harbor Act authorized an appropriation of $22,000. Of this amount, $2,375 is paid by the American Section directly to the International Association with headquarters in Brussels, lelgium. The objective of the Association--to promote the progress of inland and maritime navigation--is met by holding International Congresses and publishing technical bulletins and other documents. The Congresses are held in various member countries, usually at 4-year intervals. The Association is supported principally by member governments, but membership also extends to corporations and individuals. Member governments are represented at the Congresses and at meetings of the Permanent International Commission by delegates, the number of official delegates being based on the amount of the annual subsidy paid by the government, but not to exceed 10 in number. Corporate members may send one official representative to the Congresses. Individual membership is of two classes--Annual and Life, depending on the method of payment of dues. The affairs of the Association are managed by the Permanent International Commis- Sion composed of delegates from the supporting governments. U. S. members of the Permanent International Commission comprise the National Commission, which is the governing body of the American Section. Director of Civil Works, Office of the Chief of Engineers, U. S. Army; and Resident Member, Board of Engineers for Rivers and Harbors, are ex officio Chairman and Secretary, respectively, of the National Commission. The Secretary handles all administrative matters of the American Section. During fiscal year 1969, U. S. members of the Permanent International Commission were Brig. Gen. Charles C. Noble, USA, until January 1969, then Brig. Gen. F. P. Koisch, USA, ex officio Chairman of the National Commission; Col. A. D. Wilder, CE, USA, ex officio Secretary; Mr. Jerome O. Ackerman, Chief, Engineering Division, U. S. Army Engineer Division, Missouri River; Col. Carl H. Bronn, USA (Ret.), Executive Director, National Reclamation Association; Mr. Braxton B. Carr, President, The American Waterways Operators, Inc.; Mr. Mark S. Gurnee, Chief, Operations Division, Directorate of Civil Works, Office, Chief of Engineers; Mr. J. W. Hershey, President, American Commercial Lines, Inc.; Mr. Joseph H. McCann, Administrator, St. Lawrence Seaway Development Corporation; Mr. Duane Orr, Port of Corpus Christi; and The Honorable Theodore M. Schad, Executive Director, National Water Commission. Brig. Gen. Herbert D. Vogel, USA (Ret.), Consulting Engineer, Resource Development, and Mr. Carl B. Jansen (Ret.) are honorary members of the Commission. The annual meeting of the Permanent International Commission and the XXIInd International Navigation Congress were held in Paris, France, 14- 28 June 1969. Membership of American Section on June 30, 1969, totaled 709, consisting of 649 individuals and 60 corporate members. Federal funds from annual appropriation were expended as follows: Annual U. S. contribution to Association, $2,375; expenses of representatives to meetings in Paris, $15,- 502; translations, $200; publications, $25; total obligations, $18,102. 1305 INVESTIGATIONS AND SUPERVISION OF PROJECTS UNDER FEDERAL WATER POWER ACT Federal Water Power Act of June 10, 1920, created the Federal Power Commission, composed of Secretaries of War, Interior, and Agriculture, with authority to grant permits and licenses for hydroelectric developments in all waters over which Congress has jurisdiction. The act further required that work of the Commission be performed by and through the Departments of War, Interior; and Agriculture, and their engineering, technical, and other personnel except as may be otherwise provided by law. By act of June 23, 1930, entitled 'An Act to reorganize the Federal PoWer Commission,' sections I and 2 of Federal Water Power Act of 1920 were amended. A commission Was provided for to be composed of five commissioners to be appointed by the President, by and with the advice and consent of the Senate. Necessity of performing work through the Departments of War, Interior, and Agriculture was removed and the Commission authorized to appoint such officers and employees as necessary in executing its functions. By title II, Public Utility Act of 1935, original Federal Water POWer Act was made part I of Federal Power Act, and Parts II and III added to that act. The law also pro- Vides that no waterpower license affecting navigable capacity of any navigable waters of the United States Shall be issued until plans of the dam or other structures affecting navigation have been approved by the Chief of Engineers and Secretary of the Army. There is further provision whereby any person or corporation intending to construct project works in any stream over which Congress has jurisdiction, other than navigable waters, shall file a declaration of intention for purpose of ascertaining whether or not jurisdiction of the Federal Power Commission will attach. The following work of an engineering nature was assigned and accomplished during the fiscal year: 25 plans approved by Chief of Engineers and Secretary of the Army in accordance with sec. 4 (e) of the Federal Water Power Act; 56 reports submitted on applications for preliminary permits or licenses or amendments thereto and reports on licensed projects subject to recapture; and 9 licenses and permits under supervision. Necessary expenses in excess of nominal amounts for transportation and subsistance of personnel engaged in investigations and cost of supervision under provisions of Federal Power Act are paid from appropriations made for Federal Power Commission. All other costs of administration of laws in question are paid from funds available for general expense of the Corps of Engineers. No expenses were paid from appropriations made for Federal Power Commission during the fiscal year. 1307 MISCELLANEOUS CIVIL WORKS IMPROVEMENTS TABLE OF CONTENTS Page 1.

In order to carry out United States obligations under international agreements, the Office of the Chief of Engineers and several Divisions and Districts of the Corps with jurisdiction over areas bordering Canada, have representation on' numerous Boards and Committees. The majority of these Boards are established by the International Joint Commission (IJC) as empowered in accordance with the provisions of the Boundary Waters Treaty of 1909 between the United States and Great Britain (Canada). Their Boards fall into two broad categories: boards of control, which are more or less permanent; and engineering or technical boards, which are usually dissolved after completing their assignment. In addition to Boards created by the Commission, other boards and committees are created by treaties or other informal arrangement in matters concerned with the water resources, 1309 Page REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 and the members report directly to the Government or establishing agency. A listing of the Boards having Corps of Engineer membership follows: 2A. THE INTERNATIONAL ST. CROIX RIVER BOARD OF CONTROL Constitution and duties. The Board was organized pursuant to conditions in the orders of the International Joint Commission approving the maintenance and operation of the dam built by the St. Croix Water Power Co. and the Sprague Falls Manufacturing Co., Ltd., across the St. Croix River at Grand Falls, Maine, and subsequent agreements reached between the Governments of the United States and the Dominion of- Canada. The Board is charged with the duty of formulating and administering rules under which the power plant and accessories are to be operated to prevent as nearly as possible a level of water at the dam higher than 203.5 (mean sea level datum), and to secure the users of water below Grand Falls the flow of water to which they are entitled. The Board is also charged with the supervision of the operation of all fishways on that portion of the St. Croix River that forms the international boundary. On October 2, 1934, the International Joint Commission issued an order approving the reconstruction of the dam by the Canadian Cottons, Ltd., extending across the St. Croix River from Milltown, New Brunswick, Canada, to Milltown, Maine, which contained the following conditions: (a) Reconstructed dam to be operated to insure that the forebay levels rise to no higher elevation than that which was obtained in the operation of the dam now being replaced; (b) during floods the sluiceways of the dam shall be sufficiently open to insure passage of the river flow; and (c) operation of the dam, insofar as is necessary to insure the observance of the provisions of this Order, be under the supervision of the International St. Croix River Board of Control. On November 19, 1965, the Commission directed the Board of Control, in addition to the duties previously assigned, to carry out the duties contained in the Order of Approval dated October 15, 1965, for the construction of the storage dam at Vanceboro and requested that future reports be submitted semiannually. Members of the Board of fiscal year. Colonel Frank P. Bane, Division Engineer, New England Division, United States Department of the Army, at Waltham, Massachusetts, United States Member, appointed October Ist, 1968; and Mr. John E. Peters, District Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, at Ottawa; Ontario, Canadian Member, appointed November 16, 1955. Operations during fiscal year. Supervision was maintained and inspections were made by the Canadian and the United States members to ensure that the Orders of Approval of the International Joint Commission were carried out. On July 9, 1968, the Board of Control made its Annual Inspection of the St. Croix River Basin and met with officers of the New Brunswick Electric Power Commission at Milltown, New Brunswick, and the Georgia Pacific Corporation in Woodland, Maine. The International Joint Commission held a Public Hearing in St. Stephen, New Brunswick, on September 17, 1968, pertaining to the application of the St. Croix Paper Company to reconstruct the dam at Forest City and on the pollution of St. Croix River. Mr. J. W. Leslie, represented the United States Member, and Mr. J. E. Peters, the Canadian Member, were present on behalf of the International St. Croix River Board of Control. Mr. Peters expressed the responsibilities of the Board and presented the operating rules for the regulating dam at Forest City. Subsequent to the meeting, the application of the St. Croix Paper Company was approved by the International Joint Commission but was terminated owing to the inability of the applicant to accept the conditions set out in the I.J.C. Order of Approval dated October 11, 1968. The New Brunswick Electric Power Commission continued its work on the installation of its No. 6 generating unit in Milltown Station. A similar seventh unit is planned to be in operation by September 1969. The Georgia Pacific Corporation reports all the work planned on the Grand Falls Dam for 1968 was completed in November 1968. This work included grouting and placing reinforced steel into the buttresses, where required. This structure is now considered in excellent condition. Routine inspections were made by field staffmembers to verify the accuracy of the data submitted by the reporting companies. The Georgia Pacific Corporation has recorded its intention to install pollution abatement measures at its Woodland mill. Design of these measures is presently underway. Proposed operations. Such correspondence and inspection as may be necessary to carry out the Orders of Approval of the International Joint Commission will continue. 1310 MISCELLANEOUS CIVIL WORKS 2B. INTERNATIONAL LAKE MEMPHREMAGOG BOARD Constitution and duties. Lake Memphremagog is in northern Vermont and southeastern Quebec and has as its outlet Magog River in Canada. In 1920, a petition filed by the city of Newport and towns of Derby, Coventry, and Barton, Vt., alleged they had been harmed by high lake levels attributable to construction and operation of power plants on the Magog River. As a result, an international body composed of one engineer each from the United States and Canada, entitled 'International Lake Memphremagog Board,' was appointed to consider the matter and submit a joint report to each Government as to the level or levels at which Lake Memphremagog should so far as possible be maintained. At the request of local interests, consideration of the problem was suspended until 1931 when a survey was made. Subsequently a joint report by the two members of the Board, dated May 14, 1934, was submitted to their respective Governments. This report recommended that the levels of the lake under normal flow conditions range between an upper elevation of 682.70 feet above mean sea level (Geodetic Survey of Canada, 1923, adjustment), and a lower limit of 678.85 feet above the same datum. During flood conditions, the sluiceways of the dam shall be so operated as to reduce the flood water elevations to the normal regulated level of 682.70 as rapidly as possible. The Board was reactivated in August 1960 as a result of a complaint on July 20,1959, by a resident of Newport, Vt., concerning high lake levels due to alleged improper operation of the power plant. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Staff Officer, Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, for Canada and Col. Harvey L. Jones, District Engineer, New York District, U. S. Army Corps of Engineers for the United States. Operations duringfiscalyear. None. Table 48-B contains data based on daily readings of the elevation of Lake Memphremagog at Newport, Vt., from July 1, 1968 to June 30, 1969, furnished by the Water Resources Branch of the U. S. Geological Survey. Datum of the gage is 673.00 feet above mean sea level, U. S. Geological Survey 1929 adjustment which is 0.3 feet greater than Geodetic Survey of Canada 1923 adjustment. 2C. INTERNATIONAL LAKE CHAMPLAIN BOARD OF CONTROL Constitution and duties. The Board was organized pursuant to the provisions of the orders, dated June 10, 1937, of the International Joint Commission, approving construction and operation of certain remedial works in Richelieu River at Fryer's Island, Quebec. The Board is responsible for insuring compliance with provisions of the order of approval insofar as they relate to the regulation of the levels of Lake Champlain. Members of the Board for fiscal year. Mr. N. P. Persoage, Inland Waters Branch, Department of Energy, Mines and Resources, for Canada, and Col. Harvey L. Jones, District Engineer, New York District, U. S. Army Corps of Engineers, for the United States. Operations and results during fiscal year. Construction of the dam at St. Ours on Richelieu River was essentially completed early in 1969. Studies have been continued by the Canadian Department of Transport to determine the best method of maintaining navigation between the Chambly Basin and St. Johns, Quebec, in view of the rapidly deteriorating condition of the Chambly Canal. Further experiments may be carried out with low head at the Fryers Island dam whereby some water will be impounded to improve conditions at Ile Ste. Therese. The effect of any such operation will not extend upstream of the rapids located between Ile Ste. Therese and St. Johns. 2D. INTERNATIONAL ST. LAWRENCE RIVER BOARD OF CONTROL Constitution and duties. The International St. Lawrence River Board of Control was established December 16, 1953 pursuant to the provisions of the Order of Approval dated October 29, 1952, of the International Joint Commission for the construction of certain works for the development of power in the International Rapids Section of the St. Lawrence River. The Commission instructed the Board to perform the duties assigned to it by the Order of Approval of October 29, 1952. These responsibilities include the following items: (a) The Board of Control is to determine the gages, measurements and other services to be provided by the Power Authority of the State of New York and the Hydro-Electric Power Commission on Ontario in order to furnish accurate records relating to water levels and the discharge of water through the works and the regulation of the flow of water 1311 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 through the International Rapids Section; (b) Upon completion of the works the duties of the Board shall be to insure that the provisions of the Commission's Orders relating to water levels and the regulation of the discharge of water from Lake Ontario and the flow of water through the International Rapids Section are complied with, and the Hydro-Electric Power Commission of Ontario and the Power Authority of the State of New York shall duly observe any direction given them by the Board of Control for the purpose of insuring such compliance. The Board of Control shall report to the Commission at such times as the Commission may determine; and (c) In addition to the reports to be made by the Commission in accordance with the terms of the Orders of Approval, the Board was requested to report at the Commission's semi-annual meetings and also to keep the Commission currently informed with .regard to the discharge of water from Lake Ontario and the flow through the International Rapids Section of the St. Lawrence River. At a meeting of the International Joint Commission in Toronto on January 25, 1957, studies of the regulation of Lake Ontario in furtherance of such studies accomplished by the International Lake Ontario Board of Engineers, were assigned to the International St. Lawrence River Board of Control. Members of the Board. The Canadian members of the Board for Fiscal Year 1969 were: Mr. T. M. Patterson, Special Advisor to the Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, Chairman of the Canadian Section until his retirement on March 20,1969 when he was succeeded as Chairman by Mr. D. M. Ripley, Director, Marine Hydraulics Branch, Department of Transport and former Vice-Chairman of the Board; Mr. J. B. Bryce,. Hydraulic Engineer, Hydro-Electric Power Commission of Ontario; Mr. Y. DeGuise, Commissioner, Hydro- Electric Power Commission of Quebec; and Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources. Mr. Clark was appointed to succeed Mr. Ripley as Vice-Chairman of the Canadian Section of the Board. The United States members of the Board were: the Division Engineer, U. S. Army Engineer Division, North Central, Chairman, ex-officio, U. S. Section; Mr. Thomas M. Crum, Deputy to the Chief, Division of Licensed Projects, Federal Power Commission; Mr. J. B. McMorran, Commissioner, Department of Transportation, State of New York; and Mr. F. F. Snyder, Hydraulic Engineer, Office, Chief of Engineers, U. S. Army Corps of Engineers (Retired). Brigadier General Robert M. Tarbox was Division Engineer, U. S. Army Engineer Division, North Central during Fiscal Year 1969. Activities of the Board during fiscal year. During the fiscal year the Board presented its Thirtieth and Thirty-First Progress Report to the International Joint Commission. The Board also testified at the November 19, 1968 public hearing held at Cornwall, Ontario by the Commission on the matter of the application of the Raisin Region Conservation Authority for approval of 25 cubic feet per second of water from the International Rapids Section of the St. Lawrence River into the Raisin River near Cornwall, Ontario. The Board of Control approved the Twenty-Eighth and Twenty-Ninth reports by the Committee on River Gaging, a Committee of the Board which provides and maintains a comprehensive program for recording river levels and flows. The Power Entities of both countries have installed the necessary gages requested to date and the required records are being obtained. The Committee on River Gaging keeps the Board of Control advised regarding the gaging program. During the year the levels and outflows have continued to be regulated in accordance with the International Joint Commission directive of April 8, 1960 that, commencing on April 20, 1960, the St. Lawrence project be so operated as to conform to the criteria and other requirements of the Commission's Orders of Approval dated October 29, 1952, and July 2, 1956. Regulation Plan 1958-D is the plan currently approved by the Commission for use by the Board in consulting with the Power Entities and other interests concerned in compliance with the criteria and other requirements of the Order of Approval. The Commission approved the request for diversion of 25 cubic feet per second of water from Lake St. Lawrence by the Raisin Region Conservation Authority. In accordance with Condition (4) of the Commission's Order of Approval, dated December 31, 1968, the Board will set up procedures for recording and reporting the water withdrawals. The supplies to the Great Lakes have remained generally favorable during the reporting period. There were no violations of the approved range of stage during the reporting period. Under its discretionary authority, with continuing guidance from the International Joint Commission and with advice from the interests involved, the Board of Control has regulated the Lake Ontario outflow to best meet the requirements set forth in the Order of 1312 MISCELLANEOUS CIVIL WORKS Approval. In some instances this has involved storage of water by flowing less than minimum flows under the present regulation plan; in other instances water has been taken from storage. Peaking tests were continued throughout the period and ponding was authorized during the non-navigation season. There has been no system emergency requiring additional flow during the winter season. During the winter no problems related to ice formation were encountered. 2E. INTERNATIONAL NIAGARA BOARD OF CONTROL Constitution and duties. The Board was established August 19, 1953 by directive of the International Joint Commission to supervise the construction, maintenance and operation of the Niagara Remedial Works, recommended by the International Joint Commission in its 1953 report on the 'Preservation and Enhancement of Niagara Falls.' Members of the Board. The United States Members of the Board were the Division Engineer, U. S. Army Engineer Division, North Central, Corps of Engineers, Chairman, ex-officio, U. S. Section; and Mr. Thomas M. Crum, Deputy to the Chief, Division of Licensed Projects, Federal Power Commission. Brigadier General Robert M. Tarbox was Division Engineer, U. S. Army Engineer Division, North Central, during Fiscal Year 1969. The Canadian Members of the Board during the year were Mr. T. M. Patterson, Special Advisor to the Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, Chairman of the Canadian Section until his retirement on March 20, 1969 when he was succeeded as Chairman by Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources; and Mr. Gerald Millar, Chief Engineer, Harbors and Rivers Engineering Branch, Department of Public Works. Activities during fiscal year. The Board met in Ottawa on October 7, 1968; presented its Thirty-First Progress Report to the International Joint Commission on October 8, 1968; met in Sault Ste. Marie, Ontario on February 12, 1969, in Washington, D. C. on April 22, 1969; presented its Thirty-Second Progress Report to the International Joint Commission on April 22, 1969 and met again in Niagara Falls, Ontario on June 17; 1969. A report on the effectsof power operations on the Niagara River and Lake Erie is presently being prepared for the Board by its Working Committee. The report will include the results of recent discharge measurements on the Niagara River. The Lake Survey District, Corps of Engineers and Inland Waters Branch, Department of Energy, Mines and Resources made flow measurements on each side of Grand Island during May, June, August and November 1967 to check the existing discharge equations. Although the study of means of preserving or enhancing the scenic beauty of the American Falls is primarily a function of the American Falls International Board, some aspects of that study are pertinent to the International Niagara Board of Control because of possible effects on levels of the Maid-of-the- Mist pool, Grass Island pool, etc. The temporary cofferdam across the head of the American Channel between Goat Island and the U. S. mainland for dewatering the Falls was constructed by June 12, 1969. The ice boom in the outlet from Lake Erie, referred to in previous reports, was fully reinstalled on December 4, 1968 and removed by April 3, 1969. Over the past five winters the ice boom has functioned successfully. Not only has it very substantially improved the utilization of water for the production of power and resultant dependability but has also greatly reduced ice damage to other interests. By letters dated June 13, 1968 the Power Entities have recommended that a later date be considered for removal of the Niagara River-Lake Erie ice boom than specified by the IJC Order of Approval. Although the late season broken ice runs this year were relatively minor, and no serious problems were encountered, the potential for major ice runs certainly exists. The International Joint Commission scheduled a hearing in Buffalo, New York on July 29, 1969 to consider later removal of the ice boom. During the past year the gates in the control structure have been operated to maintain the pool within the limits set by the Board. On days when there are ice runs or storms the normal operating limits for the Chippawa-Grass Island Pool may be suspended temporarily and, under such circumstances, the Power Entities diverting water from the pool are expected to use their best judgment in controlling the flow. The Board has closely observed the operation of the control structure to assure that operation was in accordance with instructions. No unusual maintenance problems have occurred during the year. 2F. INTERNATIONAL NIAGARA COMMITTEE Constitution and duties. The Treaty of 1950 between Canada and the United States concerning the 1313 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 uses of waters of the Niagara River was signed on February 27, 1950. By its provisions, limitations on the diversions of Niagara River water for power in accordance with Article V of the Treaty of 1909 are terminated and temporary international agreements for the allocation of waters of the Niagara River for power purposes are replaced. In accordance with provisions of Article VII of the 1950 Treaty, a representative was appointed by each government who, acting jointly, shall ascertain and determine the amounts of water available for the purposes of this treaty, and shall record the same and shall also record the amounts of water used for power diversions. By an exchange of notes during January 1955, the two Governments officially designated the representatives appointed in conformance with Article VII of the 1950 Treaty as the International Niagara Committee. With regard to flows and diversions, the Treaty of 1950 became effective October 10, 1950. Under terms of the treaty, all waters in excess of certain minimum flows which are required to maintain the scenic spectacle at Niagara Falls are available for diversion for power and, with the exception of the 5,000 cubic feet per second authorized October 1940 for diversion by Canada, are to be allocated equally between both countries. Minimum flows over the Falls shall be not less than 100,000 cubic feet per second between 8 a.m. and 10 p.m. E.S.T. from April 1 to September 15, and 8 a.m. to 8 p.m. from September 16 to October 31. At all other times the flow over the Falls shall be not less than 50,000 cubic feet per second. A brief history regarding the measurement and supervision of diversion of waters from the Niagara River prior to the designation of the representatives appointed under Article VII of the 1950 Treaty as the International Niagara Committee is included in the Annual Report for 1955. Members of the Committeeforfiscal year. The Committee consists of two members, one .representing Canada and one representing the United States. The Canadian representative was Mr. T. M. Patterson, Special Advisor to Assistant Deputy Minister (Water), Department of Energy, Mines and Resource, Ottawa, until his retirement on March 20, 1969 when he was succeeded by Mr. R. H. Clark, Special Advisor to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, and the U. S. Representative, ex-officio, was the Division Engineer, U. S. Army Engineer Division, North Central, Corps of Engineers. Brigadier General Robert M. Tarbox was Division Engineer, U. S. Army Engineer Division, North Central during Fiscal Year 1969. Operations during fiscal year. The Committee received daily reports of operation of the hydro-electric generating stations on the Niagara River which diverted water from the river above the Falls, and the DeCew Falls Plant, which diverts water from Lake Erie through the Welland Canal. These reports, submitted in the form prescribed by the Committee and showing for each hour the quantities of water diverted by each plant, were checked by the Committee. Monthly and annual summaries were prepared. The Committee included with each monthly summary an explanation of any treaty violation which may have occurred during the month. The Committee has computerized its monthly report in the interest of accuracy and efficiency. Bi-weekly and intermittent inspections of all plants were made by representatives of the Committee jointly and individually to obtain independent watt meter readings of power output.'Records of water levels in the Niagara River above and below the Falls were obtained by means of self-registering gages. It was brought to the attention of the International Niagara Committee that in the past there have been minor differences between the data developed from the Lake Survey District's gage and the telemeter gage of the Power Entities, both of which are located in the same Ashland Avenue gage installation. Although the differences were not large, certain inconsistencies in the records were created. Representatives of the Committee and the Power Entities met on February 9, 1968 to discuss these differences. Agreement was reached to use, in general, the data from the Power Entities telemeter gage subject to continuing checks for accuracy. Specific procedures established will eliminate differences in the data used for record purposes at the Ashland Avenue gage in the Maid-of-the- Mist Pool. In May 1969 the International Niagara Committee approved the new procedures for computing Niagara River flow, including the continued use of the Power Entities' telemeter gage for official record purposes. Other pertinent information. In July 1968 the Governments of Canada and the United States initiated discussions concerning the construction of a temporary cofferdam between Goat Island and the United States mainland and the use of the diverted American Falls flow for power purposes. In separate exchange of notes on March 21, 1969, the Governments of the United States and Canada authorized the construction of the cofferdam and provided an agreement for additional temporary diversions from the Niagara 1314 MISCELLANEOUS CIVIL WORKS River for power production purposes. This agreement became effective upon confirmation by the U. S. Senate of the agreement concerning the use of the water diverted from the American Falls by placement of the cofferdam. The cofferdam is to be removed no later than December 31, 1969. The notes for additional diversion permitted for power purposes state that minimum flows over the Falls stipulated in Article IV of the Niagara River Treaty of 1950 shall be reduced from 100,000 to 50,- 000 cfs, respectively, to 92,000 and 41,000 cfs, respectively, during the hours designated in that treaty. Any water in excess of these new temporary minimums may be diverted for power purposes; provided that when the 41,000 cfs minimum applies, at least 9,000 cfs of the waters thus diverted shall be either passed through the low-head plants or released to the Horseshoe Falls so as to maintain a minimum flow of 50,- 000 cfs into the Maid-of-the-Mist Pool at all times. The Power Authority of the State of New York and the Hydro-Electric Power Commission of Ontario had agreed that each would contribute in cash or in services a total estimated value of $385,000, if the additional diversion were permitted during the original computed basis of period from April 30, 1969 to December 31, 1969. The contribution will be based on actual diversion on the same basis as the $385,000 figure was determined. The requirement for the cofferdam to dewater the American Falls channel is explained in the activities of the American Falls International Board. 2G. INTERNATIONAL LAKE SUPERIOR BOARD OF CONTROL Constitution and duties. The Board, established in pursuance of orders issued by the International Joint Commission May 26 and 27, 1914, is charged with the supervision of the operations of all compensating works and all power canals and appurtenances with a view to so controlling the outflow from Lake Superior as to maintain its level as nearly as may be between elevations 600.5 and 602.0 feet above mean water level at Father Point, Quebec (International Great Lakes Datum-1955) and to so control the outflow as to prevent the level of the St. Marys River below the locks from exceeding elevation 582.9. Members of the Boardfor fiscalyear. Mr. T. M. Patterson, Special Advisor to the Assistant Deputy Minister (Water), Department of Energy, Mines and Resources was the member of the Board for Canada, until February 17, 1969 when he resigned and was succeeded by Mr. R. H. Clark, Special Advisor to the Director, Inland Waters Branch, Department of Energy, Mines and Resources. The Division Engineer, U. S. Army Engineer Division, North Central was the member ex-officio, for the United States. Brigadier General Robert M. Tarbox was Division Engineer, during fiscal year 1969. Operations during fiscal year. The Board observed conditions pertaining to the regulation of Lake Superior through representatives of Canada and the United States by field inspection and by means of regular and systematic reports of the water levels on Lake Superior, in the St. Marys River above and below the Sault Locks and control works and on Lake Huron. Records of discharge at Sault Ste. Marie through the rapids, navigation canals and power plants were also systematically reported to the Board. Changes in the rate of outflow from Lake Superior are directed by the Board as indicated by the rule curve currently in use. During the past year the Board has continued the use of the modified plan of operation under the rule curve of 1949 for the regulation of Lake Superior. During the month of July 1968 the Lake Superior Board withheld about 11,000 cfs-months of water in Lake Superior, in relation to the outflow requirements of the current plan of regulation, in order to compensate for the additional water which would be discharged later from the lake in carrying out a winter test program of the International Great Lakes Levels Board. The winter test operations were conducted at the control works as part of the Great Lakes Levels Study to determine the feasibility of increasing the maximum winter outflow under the present regulation plan for Lake Superior from 85,000 cfs to 95,000 cfs. The winter tests have been carried out satisfactorily and no problems have arisen with regard to the winter operation of the gates or with any ice jamming on the Lower St. Marys River under the increased flows. Detailed arrangements were made for continuous monitoring of the water levels in the Lower St. Marys River so that at the first sign of any impending ice build-up or flooding, immediate preventive action would be taken. Approval from the Great Lakes Power Corporation, which owns the Canadian portion of the control structure, was obtained for the operation of the gates for the winter test program. As a result of high supplies to the Lake Superior basin beginning in the spring of 1968, Lake Superior water levels increased to about 0.7 foot above average by the end of the calendar year 1968 and maximum 1315 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 outflows with all 16 gates fully open were discharged during practically all of the period, August through December 1968. Closure of the control gates to their winter settings was delayed until December 20 from the normal December 1 closing date in order to alleviate the high lake water level as much as possible. As a result an additional 20,400 cfs months of water was discharged during the month of December above the 1949 rule curve requirement of the regulation plan. Several letters written on behalf of property owners on the United States side of Lake Superior were received by U. S. representatives concerning the high water conditions. Appropriate replies were communicated in each case. No similar correspondence was experienced by the Canadian Section of the Board. 2H. INTERNATIONAL LAKE OF THE WOODS CONTROL BOARD Constitution and duties. The Convention between the United States and Great Britain proclaimed July 17, 1925, provides for the regulation of the level of the Lake of the Woods in order to secure to the inhabitants of the United States and Canada the most advantageous use of the waters thereof, and of the waters flowing into and from the lake on each side of the boundary between the two countries. The Convention also provides for the Government of Canada to establish and maintain a Canadian Lake of the Woods Control Board to regulate and control outflow of waters of the lake, and for establishment and maintenance of an International Lake of the Woods Control Board, composed of two engineers, one representing the United States and the other representing Canada, to whose approval the rate of total discharge shall be subject whenever the water level rises above elevation 1061 or falls below elevation 1056, sea level datum. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, represented Canada and Colonel Richard J. Hesse, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. Maintained supervision to insure that every effort was being made to comply with the provisions of the Convention. Three engineers of Col. Hesse's staff attended the July 1968 meeting of the Canadian Lake of the Woods Control Board in Winnipeg. On October 7, 1968 Col. Hesse and a staff engineer attended meetings of the Canadian Control Board in Ottawa: The Board members and two engineers on their staffs also met with resort owners at Warroad in March 1969 to discuss levels on Lake of the Woods. Since the snowfall for the winter was almost double that of normal and because of the extremely wet preceding fall, the Board warned the property owners to expect higher than normal water levels if even normal precipitation occurred. They were also warned that in case of abnormal precipitation to expect abnormally high stages on the lake. 21. INTERNATIONAL RAINY LAKE BOARD OF CONTROL The Convention between the United States and Canada, ratified by U. S. Senate August 30, 1940, provides in part that: 'The International Joint Commission ... hereby clothed with power to determine when emergency conditions exist in the Rainy Lake watershed, in the event the Commission shall determine that such emergency conditions exist.' On June 8, 1949, the Commission issued an order to the owners of dams at outlets of Namakan Lake and Rainy Lake, which provided for a method of regulation as recommended by International Rainy Lake Board of Control. Order provides for certain levels during the various seasons of the year as well as control of outflows, with view to securing most advantageous use of water in total to the various interests. A supplementary order dated October 1, 1957 modified regulations for Namakan Lake to provide for some variation in operation based on anticipated spring runoff. This supplementary order was extended to October 1967 and again to October 1972, by action of the International Joint Commission on October 2, 1962 and April 5, 1967, respectively. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, represented Canada, and Col. Richard J. Hesse, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. Basic data were compiled and engineering reports were submitted to the Commission. The members of the Board with members of their staffs met with resort and other property owners at International Falls in April 1969 to discuss existing water level of Rainy Lake and Namakan Chain of Lakes. Since the snowfall for the winter was also almost double that of normal the Board warned that with normal precipitation both Namakan and Rainy Lakes would more than fill. Also, abnormally high water levels would result if slightly over normal 1316 MISCELLANEOUS CIVIL WORKS precipitation occurred during spring thaws. As a result of this information, several of the property owners indicated a desire for lower maximum operating levels. Runoff during the winter was the highest of record. An unprecedented high outflow occurred from Namakan Lake where the dam outlet was opened fully on February 5, 1969 and remained open to date. Even so, Namakan Lake reached maximum rule curve level on 4 June and has remained at substantially this level to the end of the fiscal year. Rainy Lake also reached maximum rule curve on 4 June when the dam outlet was opened wide. This level has also remained at substantially this level to the end of the fiscal year. On August 9, 1968 the International Rainy Lake Board of Control met at St. Paul with Mr. P. O. O'Leary, an attorney, and his clients who were bringing suit against the Boise Cascade Paper Company, charging negligence in the operation of the Kettle Falls Dams at the outlet of Namakan Lake. On October 8, 1968 the International Rainy Board of Control met with the International Joint Commission in Ottawa to discuss the advisability of an early examination and further measures of regulating that part of Lake of the Woods pertaining to the Rainy River Basin. On April 24, 1969 the same Board presented a report to the International Joint Commission suggesting revised rule curves and proposed new orders. The International Joint Commission took the revisions under advisement and scheduled a Public Hearing at International Falls on June 24, 1969. As a result of this meeting they are considering the proposed new rule curves. 2J. INTERNATIONAL PRAIRIE PORTAGE BOARD OF CONTROL The International Prairie Portage Board of Control was formed by International Joint Commission for purpose of furnishing it with technical advice regarding suitability of dam structure at Prairie Portage, Lake County, Minn. After approval of plans by Department of the Army and International Joint Commission, the Board was retained to advise the Commission further regarding progress of construction and any other matters which might arise concerning this project. Members of the Board for fiscal year. Mr. J. D. McLeod, Senior Engineer, Inland Waters Branch, Department of Energy, Mines and Resources, represented Canada, and Col. Richard J. Hesse, District Engineer, U. S. Army Engineer District, St. Paul, represented the United States. Operations during fiscal year. U. S. Forest Service constructed a cofferdam before World War II but postponed work on the project during the war. On June 12, 1968 after a period of heavy rains the cofferdam was washed out, resulting in lowering the lake levels of Birch, Sucker, Moose, Newfound and Ensign Lakes. This caused considerable difficulty for boating, as shallow water exists at the outlet of the lakes. By November 10, 1968 the U. S. Forest Service completed reconstruction of the Prairie Portage cofferdam which has been functioning satisfactorily at the control dam for the lakes. The reservoir was refilled by December 25, 1968. Although there was exceedingly heavy snow in the basin last winter, the runoff this spring was not excessive due to ideal melting conditions. Levels only slightly above normal resulted in the Spring. 2K. INTERNATIONAL KOOTENAY BOARD OF CONTROL LAKE Constitution and duties. The Board was organized to secure compliance with the provisions of the orders of the International Joint Commission dated November 11, 1938, and August 5, 1949, relating to the construction and operation of control works by the Consolidated Mining and Smelting Co., of Canada, Ltd., through the West Kootenay Power and Light Co., Ltd., in and adjacent to the channel of the Kootenay River, and regulation of the levels of Kootenay Lake in the Province of British Columbia.

Operations during fiscal year. The Board did not meet. An annual report was submitted to the Commission. 2M. INTERNATIONAL SKAGIT RIVER BOARD OF CONTROL Constitution and duties. The International Joint Commission approved on January 27, 1942 an application by the city of Seattle to raise Ross Dam to impound Skagit River water to a maximum elevation 1725 feet above mean sea level at the international boundary, subject to a binding agreement being entered into between the city of Seattle and the Government of British Columbia providing for indemnifying British Columbia for any injury that may be sustained by reason of the city's operations on the Skagit River. This Order of Approval provided for the appointment of the International Skagit River Board of Control, to consist of two members, one from the engineering services of Canada and the other from the engineering services of the United States, but the Commission did not establish the Board at that time. On January 10, 1967, the Province of British Columbia and the city of Seattle entered into a 99 year agreement permitting flooding of the lands of the Skagit River watershed in British Columbia up to elevation 1725 feet, North American Datum (1927) as established by the Geodetic Survey of Canada. In a directive to the International Skagit River Board of Control dated July 31, 1967, the Commission stated that the Board was established on April 4, 1967. Members of the Board for fiscal year. H. T. Ramsden, District Engineer, Water Survey of Canada, Department of Energy, Mines and Resources, Vancouver, British Columbia, for Canada, and Col. R. E. McConnell, District Engineer, U. S.

The water surface at the international boundary reached a maximum elevation of 1603.37 feet on August 3, 1968, as recorded by the gaging station, Skagit River, at the international boundary near Hope. On October 28, 1968, the board members visited the Skagit River at the international boundary. Seattle City Light officials briefed the Board on some tentative plans to increase the height of Ross Dam as permitted in the Commission's Order of Approval dated January 27, 1942. The board members made no other visits to the area during the year. An annual report was submitted to the Commission. 2N. INTERNATIONAL SOURIS-RED RIVERS ENGINEERING BOARD Constitution and duties. The Board was established April 1948 by the International Joint Commission to investigate and report on the water resources of a broad area along the international boundary extending from the Milk River drainage basin in the west up to and including the drainage basin at the Red River of the North on the east. The Board reported in 1959 to the Commission that, with the possible exception of the Pembina River there were no significant problems on international streams within the terms of the January 12, 1948 Reference and assignment.

Subsequently, the Commission prepared a separate report, dated October 1967, which was furnished to the Governments of Canada and the United States. No action has been taken by either Government to date. 2P. INTERNATIONAL SAINT JOHN RIVER ENGINEERING BOARD Constitution and duties. The Board was established September 28, 1950 by the International Joint Commission to determine if the waters of the Saint John River system could be more beneficially conserved and regulated. The Board's report was submitted to the Commission in April 1953. It outlined several projects, the development of which would be practical and in the public interest. The Commission submitted its interim report to the two governments in April 1954. Since then the services of the Board have been retained to advise the Commission, keeping the latter informed at least annually on any resource developments being undertaken or proposed by entities in either country. Members of the Board for fiscal year. The Board consists of four members, two from each country. The Canadian representatives were Mr. J. D.

The Board did not meet during the year, but it reviewed developments within the basin and reported to the International Joint Commission. The State of Maine passed a bill during the 1969 session which classifies the main stem of the Saint John River for beneficial uses. Also the State developed water quality standards for the Saint John River. 2Q. INTERNATIONAL GREAT LAKES LEVELS BOARD Constitution and duties. The Governments of Canada and the United States, by Joint Reference dated October 7, 1964, requested the International Joint Commission to determine whether measures within the Great Lakes Basin can be taken in the public interest to regulate further the levels of the Great Lakes or any of them and their connecting waters so as to reduce the extremes of stage which have been experienced, and for the beneficial effects in these waters. The Reference further stated that the two Governments will upon request make available to the Commission the services of engineers and other specially qualified personnel of their governmental agencies and such information and technical data as may have been acquired by them during the course of the investigation. 1319 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 At a meeting on December 2, 1964, the International Joint Commission established the International Great Lakes Levels Board to undertake the necessary investigations and studies and to advise the Commission on all matters which it must consider in making a report or reports to the Governments under the Reference. At the first meeting of the Board on January 6, 1965, a Working Committee was selected. The International Great Lakes Levels Working Committee met on July 7, 1965 and set up four Subcommittees to investigate and report on the separate areas of study involved - Shore Property, Navigation, Power and Regulation. A Subcommittee on Regulatory Works was subsequently established by the Working Committee in September 1967. The International Study program is being considered in two broad phases: the first phase consists of the collection and compilation of basic data, the development of methodology for evaluating regulation plans in respect of their effects on the various Great Lakes interests, the investigation of regulation techniques .and the preparation of preliminary plans. Work during the fiscal year was mainly in this phase. In the second phase, information assembled under the work programs pertaining to shore property, navigation and power will be used, together with the results of the regulation plans, to establish regulation criteria and to develop improved plans. The second phase will also consider the cost and design of any associated regulatory works and preparation of the Board's final report to the Commission. Members of the Board for fiscal year. The Board consists of six members, three representing the United States and three representing Canada. U. S. members were Mr. L. G. Feil, Chief of Planning Division, Civil Works, Office, Chief of Engineers, U. S. Army, Chairman of the United States Section; Mr. Mark Abelson, Regional Coordinator, Northeast Region, Department of the Interior, (acting member to replace Mr. C. H. Stoddard who resigned); and Mr. B. T. Jose, Assistant Administrator, St. Lawrence Seaway Development Corporation, Department of Transportation. Canadian Members were Mr. T. M. Patterson, Special Advisor to Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, Chairman of the Canadian Section; Mr. C. K. Hurst, Chief, Maintenance and Operations, Harbors and Rivers Engineering Branch, Department of Public Works; and Mr. R. H. Smith, Chief, Hydraulics Study Division, Department of Transport. The Working Committee consists of seven members, four representing the United States and three representing Canada. U. S. Members of the Working Committee were Brigadier General R. M. Tarbox, Division Engineer, U. S. Army Engineer Division, North Central, Corps of Engineers, Chairman, ex-officio, U. S. Section; Mr. Mark Abelson; Mr. A. J. Buchar, Director of Field Service, Chicago Field Office, Department of Commerce; and Mr. J. H. Spellman, Deputy Regional Engineer, New York Regional Office, Federal Power Commission. Canadian Members of the Working Committee were Mr. R. H. Clark, Special Adviser to the Director, Inland Waters Branch, Department of Energy, Mines and Resources, Chairman of the Canadian Section; Mr. D. W. Quinlan, Chief Engineer, Planning, Department of Public Works; and Mr. John Bathurst, Special ProjectsEngineer, Department of Transport. Membership on the subcommittees is drawn from agencies participating in the study and represented on the Board and Working Committee. Activities during fiscal year. Basic data have been complied by the Subcommittees on Shore Property, Navigation, and Power, and a preliminary plan developed by the Subcommittee on Regulation was tested for the effects on the various interests. The Subcommittee for Regulatory Works has initiated investigations for providing regulatory works necessary in the outlet river of the lake to be regulated. The effects of the preliminary test regulation plan on the shore property, navigation and power interest will be evaluated. The results of the evaluation of a four-lake regulation plan and a three-lake regulation plan have been reviewed and compared with results of earlier plans. Optimization techniques are being used to establish the maximum net benefits which could be expected from regulation of these lakes. A computer program has been developed for this purpose and will be used in the testing and design of future regulation plans. An investigation for increasing the flexibility of Lake Superior was undertaken, specifically, to determine the ability to pass winter flows in excess of 85,- 000 cfs. If the tests prove the feasibility of higher winter flow, regulation plans will be developed with higher maximum winter outflows. A comparison will be made between the cost of operating control gates in winter to achieve the higher flows and the economic benefit which would ensue therefrom. 1320 MISCELLANEOUS CIVIL WORKS An experimental winter operation of the gates of the Lake Superior Control Works at Sault Ste. Marie was completed for the 1968-69 winter. Three additional gates were opened providing a total flow of 95,- 000 cfs. Sufficient knowledge and experience was gained to verify that the guides could be deiced to permit gate movement under adverse conditions. Under the conditions prevailing during the experiment, the tests have demonstrated that a winter flow of 95,000 cfs is possible through the gates and St. Marys River without ice jamming problems. It is planned to continue the tests during future winters to verify the feasibility of passing a flow of 95,000 cfs under a variety of winter conditions. Development of preliminary criteria for regulation is underway. The preliminary criteria will be subject to considerable subsequent modification as a result of future economic evaluations and further considerations in regard to the requirements of the various interests concerned with lake regulation. Work has been completed on the general format and schedule for the Final Report of the Board to the Commission. The Board has selected a project period for each of the lakes for the purpose of benefit and cost evaluation. The Levels Board studies are being coordinated with the Provinces and States which border on the Great Lakes and their outflow rivers. Personnel of the appropriate Provincial and State Agencies are cooperating, with those of the participating Federal Agencies. 2R. AMERICAN FALLS INTERNATIONAL BOARD Constitution and duties. In a Reference dated March 31, 1967, the Governments of the United States and Canada, pursuant to Article IX of the Boundary Waters Treaty of 1909, requested the International Joint Commission to investigate and report upon measures necessary to preserve and enhance the beauty of the American Falls at Niagara. The American Falls International Board was established July 24, 1967, by directive of the International Joint Commission to carry out the investigations required under the Reference. Members of the Board for fiscal year. The U. S. members of the Board were: the Division Engineer, U. S. Army Engineer Division, North Central, Corps of Engineers, Chairman, ex-officio, of the U. S. Section; and Mr. Garrett Eckbo, Chairman, Department of Landscape Architecture, University of California, Berkeley, California. Brigadier General Robert M. Tarbox was Division Engineer, U. S. Army Engineer Division, during fiscal year 1969. Canadian Members were: Mr. T. M. Patterson, Special Advisor to Assistant Deputy Minister (Water), Department of Energy, Mines and Resources, Chairman of the Canadian Section, and Mr. H. S. M. Carver, Chief Advisory Group, Central Mortgage and Housing Corporation, Ottawa, Canada (Retired). Activities during fiscal year. The International Joint Commission approved generally the Board's Plan of Study on July 24, 1968. This document describes by what measures the Board intends to carry out the investigations by utilizing a temporary cofferdam between Goat Island and the United States mainland. This would be done in order to dewater the American Falls to permit exploratory work in the unwatered area of the American channel, on the face of the Falls, and of the fallen rock at the base. The proposal to temporarily divert water from the American Falls was submitted during FY 1968 by the Commission to the two Governments for consideration. The Board directed that the Buffalo District office of the Corps of Engineers should act on its behalf in completing arrangements for construction of the cofferdam and in the conduct of the geologic investigations within the study area. The International Joint Commission requested the American Falls International Board to provide an evaluation of the ecological factors involved during the dewatered period of the proposed study. A consulting ecologist conducted an on-site investigation in September 1968 and presented his findings and recommendations in a report. The Board concluded from the material presented in the report that the dewatering will cause no lasting detrimental effect on aquatic insects, fish and attached algae. The Commission agreed with this conclusion. The Board's plans include measures to protect terrestrial vegetation on the shore and smaller islands by installing water pipelines along both sides of the channel from the cofferdam at the head of Goat Island to the crest of the Falls, and to tap these lines as necessary to provide supplementary irrigation water. The Rochester Shale underlying the crest of the Falls will also be kept wet in order to prevent drying out and possible deterioration of this strata during the dewatered period. 1321 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 The Board at an executive session with the International Joint Commission on April 9, 1968, discussed the scope of the aesthetic studies under the American Falls Reference. The Board prepared a report as directed by the Commission outlining the scope and cost of three alternative aesthetic study programs for treatment of the American Falls in terms of environment to be considered. It concluded that the proposed environmental study might be carried out in three stages, the Commission to review the matter on completion of stage one of the study, to determine the desirability of proceeding with the second and/or third stages. The Commission recommended to the two Governments that this proposed study be undertaken. Discussions between the two Governments started in July 1968 concerning the construction of a temporary cofferdam between Goat Island and the United States mainland and the use of the American Falls diverted flow for power purposes. In separate exchange of notes on March 21, 1969, the Governments of the United States and Canada authorized the construction of the cofferdam and provided an agreement for additional temporary diversions from the Niagara River for power production purposes. This agreement became effective upon confirmation by.the U. S. Senate of the agreement concerning the use of the water diverted from the American Falls by placement of the cofferdam. The time required for the completion of the exchange of notes between the two Governments and a shortage of U. S. appropriated funds delayed the beginning of the cofferdam construction until early in June 1969 instead of the original mid-April 1969 date. The Power Entities subsequently indicated their willingness to participate, in cash or in service, on the basis of a shorter period of diversion and use of the American Falls normal flow for power generation. The notes for additional diversion permitted for power purpose state that minimum flows over the Falls stipulated in Article IV of the Niagara River Treaty of 1950 shall be reduced from 100,000 and 50,000 c.f.s., respectively, to 92,000 c.f.s. and 41,000 c.f.s., respectively, during the hours designated in that Article. Any water in excess of these new temporary minimums may be diverted for power purposes; provided that when the 41,000 c.f.s. minimum applies at least 9,000 c.f.s. of the waters thus diverted shall be either passed through the low-head plants or released to the Horseshoe Falls so as to maintain a minimum flow of 50,000 c.f.s. into the Main-of-the-Mist Pool below the Falls at all times. The Power Authority of the State of New York and the Hydro-Electric Power Commission of Ontario had agreed that each would contribute in cash or in services the value of $385,000, if the additional diversion were permitted during the original computed basis of period from April 30, 1969 to December 31, 1969. The contribution will be based on the shorter period of additional diversion on the same basis as the $385,000 figure was determined. One possible alternative to enhance the beauty of the Falls proposes the placing of a structure at the outlet of the Maid-of-the-Mist Pool to raise the water levels in the Pool, to restore the approximate 15 foot loss in pool level that resulted from diversion of water allowed in the 1950 Treaty for power generation, and thereby decrease the apparent height of the talus. A river bottom topographic survey was accomplished in the Maid-of-the-Mist Pool by the Hydro-Electric Power Commission of Ontario under contract to the Department of Energy, Mines and Resources; to determine if there are any suitable locations for the disposal of the accumulated talus; to determine the feasibility and site of a possible control structure. During the fall of 1968, certain instruments were installed for recording hydrostatic pressure at the flank of the Falls and water levels upstream of the proposed cofferdam site, Maid-of-the-Mist Pool and the Whirlpool section of the Niagara River. The Board submitted to the Commission a proposed Public Information Program describing three alternative public exhibit programs of a minimum, moderate, and maximum cost. Basically, the same display material would be used on each side of the boundary. Due to the shortage of funds, the Niagara Parks Commission (Ontario) and the Niagara Frontier State Park Commission (New York) agreed to undertake a minimum display showing material describing the investigation and study. A contract was awarded by the Buffalo District, Corps of Engineers on April 29, 1969 totaling $445,- 412.00 for dewatering and support operations. The building of the cofferdam, closing the American Falls flow, commenced at 8:30 P.M. on 9 June and closure was made on 12 June at 10:30 A.M. The sprinkler system for irrigation and wetting the Rochester Shale during the dried up period was put in operation on 12 June. The area will be sounded and mapped to determine the river bottom topography. The geological studies to be undertaken during the dewatered period will cover a broad range of investigations, drilling, 1322 MISCELLANEOUS, CIVIL WORKS undermining, jointing, talus, permeability, stratigraphy laboratory testing, rock mechanics, etc. The results obtained from the teams of core drillers, survey crews, photographers, geologists, engineers and landscape architects will be coordinated with the studies of the aesthetic group to determine what measures are desirable and feasible to preserve and enhance the scenic beauty of the American Falls. The cofferdam is planned to be removed in December 1969. Widespread national and international interest has taken place in the project from writers, magazine, newspaper, television and radio medias. It has been reported that a dramatic increase in park attendance on the U. S. side had been notedsince placement of the cofferdam. 1323 REPORT OF THE CHIEF OF ENGINEERS, U.S. ARMY 1969 MISCELLANEOUS CIVIL WORKS: APPROPRIATIONS AND EXPENDITURES TABLE 48-A.
