1. CHEFUNCTE RIVER AND BOGUE FALIA, LA.

Location. The Chefuncte River rises in the upper portions of Tangipahoa and Washington Parishes, La., and flows southerly into Lake Pontchartrain, opposite New Orleans. (See U.S. Coast and Geodetic Survey Chart No. 1269, Corps of Engineers, Mis- sissippi River Commission alluvial-valley map, and Covington quadrangle.) Previous projects. Authorized by the River and Harbor Act of June 10, 1872. For further details of previous projects, see page 731, Annual Report for 1913, and page 783, Annual Report for 1938. Existing project. This provides for a channel 10 feet deep at mean low gulf level over a bottom width of 125 feet from that depth in Lake Pontchartrain to mile 3.5 of the Chefuncte River and 8 feet deep, mean low Gulf, to Washington Street, Covington, La. The total length of the improvement is 14 miles. Under ordinary conditions the mean range of tide at the mouth is about 10 inches, and near Covington about 3 inches, and the extreme range about 14 inches and 5 inches, respectively. The variation of water surface in the upper Chefuncte River and Bogue Falia, RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 549 due to floods, is about 8 feet; that in the lower Chefuncte River at Lake Pontchartrain, due to winds, is about 3 feet. The cost of new work for the existing project, completed in fiscal year 1959, was $53,121. The average annual maintenance cost during the past 5 years was $5,537.

The existing project was authorized by the following:

Local cooperation. Local interests are required to: (a) Pro- vide without cost to the United States all lands, easements, rights- of-way, and spoil-disposal areas necessary for the construction of the improvements and for subsequent maintenance, when and as required; and (b) hold and save the United States free from damages due to construction and maintenance of the project. Assurances furnished by the St. Tammany Parish Police Jury were approved by the district engineer and accepted on June 4, 1959. No rights-of-way have been requested. Terminal facilities. There are no terminal facilities on the Bogue Falia. On the Chefuncte River the town of Madisonville and the State of Louisiana, through the Department of Public Works, constructed facilities at Madisonville. The State of Louis- iana also constructed boathouse facilities for the Coast Guard Auxiliary at the mouth of the Chefuncte River. Wharves used in connection with the two boatyards have been constructed at Madisonville and Houltonville and these, in addition to small wharves constructed by owners of pleasure boats, are adequate for navigation needs. On both waterways additional sites are available if needed. Operations and results during fiscal year. Hired-labor forces prepared plans and specifications to dredge the modified channel at a cost of $2,820 and the leased dredge Pontchartrainremoved 127,100 cubic yards of material in constructing the 10- by 125- foot channel for a distance of 1.54 miles over the bar and into Lake Pontchartrain, between miles 1.35 to -0.19, during the period March 30 to April 8, 1959, at a cost of $30,959. The total cost for the new work during the fiscal year was $33,779. Condition at end of fiscal year. Because of the maintenance work performed under a previous project, the work under the project adopted in 1930 was completed in 1929, and the modification of the project adopted in 1958 was completed on April 8, 1959, between miles -0.19 to 1.35 as adequate dimensions are 550 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 available in the river from mile 1.35 to mile 3.5. The obstructions in the Chefuncte River and Bogue Falia were originally removed in 1886, and the channel through the bar was originally dredged in 1903. The controlling depths, mean low gulf (March 1959), were: Over the bar at the mouth of Chefuncte River and in the river to mile 1.35, 10 feet; to mile 11.0, 14 feet; and to mile 14.0, 5 feet. Overhanging trees cover 20 percent of water surface between miles 12.5 to 14.0. The total cost of the existing project to the end of the fiscal year was $130,281, of which $53,121 was for new work and $77,160 was for maintenance. Cost and financial statement

2. GULF INTRACOASTAL WATERWAY BETWEEN APALACHEE BAY, FLA., AND THE MEXICAN BORDER (NEW ORLEANS DISTRICT) Location. The section of the Gulf Intracoastal Waterway within the New Orleans District extends from Lake Borgne Light No. 41, near the mouth of the Rigolets, to the Sabine River, La., and Tex. The section from Lake Borgne Light No. 41 to the Mississippi River follows the Rigolets and Lake Pontchartrain to the lake end of the State-owned Inner Harbor navigation canal, thence by way of this canal to the Mississippi River, a distance of 40.5 miles. By Public Law 675, 77th Congress, approved July 23, 1942, the project was modified to provide for a landcut through the marsh from the Rigolets to a point on the Inner Harbor Navi- gation Canal about 2.25 miles from the Mississippi River, elim- inating passage through Lake Pontchartrain and five drawbridges, a distance of 30.8 miles to the Mississippi River by this route. From the Inner Harbor navigation canal to the entrance to Harvey lock, the route follows the Mississippi River for a distance of 5.5 miles. The section from the Mississippi River to Atchafalaya River, La., leaves the Mississippi River through Harvey lock about 3.3 miles above Canal Street and follows Harvey Canal No. 1 and Bayou Barataria to Bayou Villars, a landcut south of Lake Salva- dor to Harvey Canal No. 2, Harvey Canal No. 2 to Larose, La., and a landcut to Houma, La., thence over a landcut south of Bayou Black and Bayou Cocodrie, thence through Bayou Cocodrie and a landcut to Bayou Black; thence through Bayou Black, Bayou RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 551 Chene, and Bayou Boeuf to the Atchafalaya River, about 0.5 mile south of Morgan City, La., a total distance of 95.5 miles. The alternate connection with the Mississippi River in the vicinity of Algiers, La., about 10.3 miles below Harvey lock, consisting of a lock and landcut about 9 miles in length intersecting the Intracoastal Waterway at about mile 6, is complete. An alternate route from the Mississippi River at Plaquemine, La. (113 miles above New Orleans), follows Bayou Plaquemine passing Indian Village, La., and continuing on through lower Grand River to and through a lock at Bayou Sorrel in the East Atchafalaya basin protection levee, thence through the levee borrow pit to Berwick Bay; and thence through Berwick Bay to Morgan City, La., a total distance of 56 miles. This alternate route is being enlarged from the vicinity of Morgan City to Indian Village, La., and is being extended from Indian Village, La., through Bayou Grosse Tete and a new landcut to and through a new terminal lock and entrance channel to the Mississippi River in the vicinity of Port Allen, La., a total distance of 65 miles. The section from the Atchafalaya River to Vermilion River, La., begins at the western end of the Mississippi-Atchafalaya section and follows the Atchafalaya River about 2.5 miles, portions of Little Wax Bayou, Possum Bayou, cutoffs, a landcut passing through North Bend Plantation to Bayou Bartholomew, Bayou Bartholomew to Little Bay, a landcut skirting the north edge of Cote Blanche Island and the west edge of Weeks Island to Vermilion River, about 24 miles below Abbeville, La., a total distance of about 63.6 miles. Franklin Canal, St. Mary Parish, La., extends southwesterly from Franklin, La., on Bayou Teche, for 5.15 miles to Bayou Portage, a section of "The Inland Waterway from Franklin to the Mermentau River, La.," and through the bayou for 0.75 mile to the Gulf Intracoastal Waterway, 121 miles west of Harvey lock. The section from Vermilion River to Mermentau River, La., begins at the western end of the Atchafalaya-Vermilion section and follows Vermilion River 1.3 miles, a part of the Schooner Bayou cutoff canal, and a landcut running in a general northwesterly direction to Mermentau River at a point about 0.5 mile above its entrance into Grand Lake and about 16 miles below the town of Lake Arthur, La., a total distance of about 42.7 miles. Vermilion lock has been constructed about 1.75 miles west of Vermilion River to prevent the ingress of salt water from Vermilion Bay. The section from Mermentau River to Calcasieu River, La., begins at the western end of the Vermilion-Mermentau section and follows the Mermentau River upstream for about 1.5 miles, a landcut running in a west-southwesterly direction to Lake Misere, passing north of the lake and Bayou Misere, westerly to Sweet Lake, south and west of Sweet Lake, northwesterly to Bayou Tete Bois, through Bayou Tete Bois, Black Bayou, and 552 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959

cutoffs to a point on Calcasieu River about 16.6 miles below the city of Lake Charles, La., a total distance of about 37.1 miles. Calcasieu lock has been constructed near the intersection of Calcasieu River and Intracoastal Waterway, mile 238 west of Harvey lock, Calcasieu Parish, approximately 16.6 miles below Lake Charles, La. The section from the Calcasieu River to Sabine River, La., and Tex., begins at the western end of the Mermentau-Calcasieu section, and follows the Calcasieu River upstream about 1.6 miles, a landcut running in a southwesterly direction 2.8 miles, thence west 22 miles to Sabine River at a point about 3 miles below Orange, Tex., a total distance of about 27.1 miles.

Previous projects. Previous projects for the different sections of this improvement were adopted by the following River and Harbor Acts: August 11, 1888; March 2, 1907; March 3, 1909; June 25, 1910; February 27, 1911; July 25, 1912; August 8, 1917; July 18, 1918; March 2, 1919; and September 22, 1922. For further details, see pages 878-895 of Annual Report for 1924. Existing project. This provides for a waterway 384.1 miles long within the district which is 12 feet deep and 125 feet wide at mean low Gulf, except in the section between Lake Borgne Light No. 41 and New Orleans (via landcut through the marsh and Industrial Canal), 33.1 miles long, where a width of 150 feet is provided; an alternate route 9 feet deep by 100 feet wide between Lake Borgne Light No. 41 and New Orleans (via Rigo- lets, Lake Pontchartrain, and Industrial Canal), 40.5 miles long; an alternate connection with the Mississippi River below Algiers, 12 feet deep and 125 feet wide about 9 miles long; a channel 12 feet deep and 125 feet wide for the Plaquemine-Morgan City alternate route from the Mississippi-Atchafalaya section of the waterway, in the vicinity of Morgan City, through Lower Atcha- falaya River (Berwick Bay) and the borrow pit of the East Atchafalaya protection levee to and through Bayou Sorrel lock which was constructed under the existing project "Flood control, Mississippi River and tributaries," thence through Lower Grand River to Indian Village, and thence by way of Bayou Grosse Tete and a new landcut to and through a new terminal lock and entrance channel to the Mississippi River in the vicinity of Port Allen, La., opposite the lower limit of the Port of Baton Rouge; a channel 9 feet deep and 100 feet wide from Indian Village on the RIVERS AND HARBORS NEW ORLEANS, LA., DISTRICT 553 Plaquemine-Morgan City alternate route through Bayou Plaque- mine and Plaquemine lock to the Mississippi River at Plaquemine, La.; improvement of Franklin Canal as a connecting channel from Gulf Intracoastal Waterway (mile 121) to Franklin, La., to afford a channel 8 feet deep and generally 60 feet wide with a width of 100 feet in its upper 300 feet; and a salt water guard lock (Calcasieu lock) in the waterway at mile 238 west of Harvey lock. The project also provides for the following: widening at bends; passing places; mooring basins; locks or guard locks; such railroad bridges over artificial cuts as are necessary; purchase of pipeline dredge; construction and operation of new drainage canals and pumping facilities to restore parish drainage systems where intercepted; construction of movable bridges at Missouri Pacific Railroad and State Highway Nos. 31 and 996 (in lieu of the State Highway Bridge No. 31, a tunnel was constructed, and the additional cost over estimated cost of bridge was borne by local interests) ; fixed-trestle bridges for crossing of proposed landside drainage canals; lift bridges at Louisiana Highway No. 168, Port Allen, La., at Texas & Pacific Railway, Port Allen, La., and at Texas & Pacific Railway, Morley, La.; and for annual payments to the Board of Commissioners of the Port of New Orleans for use of a portion of the Inner Harbor Navigation Canal. The length of the waterway within the district is 384.1 miles via the northerly or Port Allen route, and 299.4 miles via the southerly or Harvey Canal route. Under ordinary conditions the mean range of tide is about 10 inches and the extreme range is 14 inches. A severe storm may cause a high tide of from 6 to 9 feet. The estimate of cost for new work, exclusive of amounts expended on previous projects, is $59,650,700 Federal funds, and $4,435,000 non-Federal funds (July 1959), divided as follows: Algiers lock and canal, $16,100,000, Federal funds, and $2,185, 000, non-Federal funds (July 1959); Plaquemine-Morgan City route, $27,700,000, Federal funds, and $2,250,000, non-Federal funds (July 1959), and the remainder of the waterway, $15,850,700 (1956). Construction of bulkheads and jetties at Lake Borgne and Chef Menteur, La., is considered to be inactive and is excluded from the foregoing cost estimate. The cost of this item was last revised in 1956 and estimated to be $440,000. The construction of a double-leaf bascule, four-lane highway bridge provided for under this project has become unnecessary due to the fact that the portion of the project over which the bridge was to be constructed has been incorporated in the project "Mississippi River- Gulf Outlet" which provides for a larger bridge. The average annual maintenance cost during the past 5 years was $1,753,849. 554 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959

Bayou Sorrel lock and Bayou Boeuf lock were constructed and are being maintained and operated with "Flood control, Mississip- pi River and tributaries," funds. Therefore, construction, maintenance, and operation costs are not included in the approved estimates referred to hereinbefore.

1 Permanent Appropriation Repeal Act. 2 Not mentioned in authorizing act. Local cooperation. All assurances required for the project have been furnished. For the construction of the Plaquemine- Morgan City alternate route, the local agency is required to con- vey to the United States fee title to 7 tracts and perpetual and temporary easements in an estimated 330 tracts. Deeds of conveyance have been furnished covering the seven fee tracts and 314 easement tracts all of which have been accepted. Certifi- cates of title have been furnished covering 328 tracts, all of which have been examined and curative material requested. Curative material has been completed by the local agency and final title certificates furnished covering 251 tracts. Final title was forwarded to the Chief of Engineers covering 102 tracts. Title to 10 tracts has been acquired by the United States through declaration of taking filed in Federal Court. Terminal facilities. The terminals at New Orleans which are most generally used by Intracoastal Waterway traffic are those controlled by the State of Louisiana on the Inner Harbor Naviga- tion Canal. Since April 1, 1944, the portion from the Mississippi River to its intersection with the New Orleans-Rigolets section of the Gulf Intracoastal Waterway has been under lease to the United States and is now operated by the United States, toll free, 24 hours per day. Except for the terminal facilities at New Orleans, facilities are in general confined to privately owned piers, wharves, or oil docks. At Morgan City on the Atchafalaya River there are 2 large and 3 small wharves open to all without charge. The facilities are considered adequate for existing commerce. Operationsand results during fiscal year. a. New work by hired labor: (1) For the Algiers lock and RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 557 canal: Acquisition of rights-of-way, programing and related work, soil borings and analyses, and preparation of plans and specifications for berm protection and for drainage gaps and permanent spoil areas were accomplished at a cost of $19,514. Three drainage gaps were excavated in the permanent spoil area to permit draining of impounded water in the temporary spoil area, lily booms were constructed to retain waterlilies within spoil area, and small ditches excavated to complete the drainage; 190 concrete station markers were erected on the crown of east and west levees of Algiers Canal; and the temporary spoil area was restored to its original condition. The cost of this work was $23,850. (2) For the Plaquemine-Morgan City alternate route: Acquisition of rights-of-way, preparation of plans and specifications, engineering and design, programing, and hydraulic studies were accomplished at a cost of $90,676.

The canal extends from Hanson lock to Bayou Teche through Hanson Canal and Bayou Portage to the Intra- coastal Waterway, and along the Intracoastal Waterway to mile 161, west of Vermilion Bay. (See U.S. Coast and Geodetic Sur- vey Chart No. 1116; Corps of Engineers, Mississippi River Com- mission alluvial valley map, and Foster, Bayou Sale, Jeanerette, and Derouen quadrangles; U.S. Geological Survey maps, Abbe- ville.) Existing project. This project, as modified by the River and Harbor Act approved July 24, 1946 (S. Doc. 231, 79th Cong., 2d sess.), provides for a waterway from Bayou Teche at or near Franklin, La., to the western end of Vermilion Bay, having a depth of 5 feet below mean low Gulf and a bottom width of 40 feet, with appropriate side slopes; also the purchase of the Hanson Canal. This project, reported in the Annual Report for 1924 under the headings, Intracoastal Waterway, Franklin to Mermentau, La., RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 563 and Intracoastal Waterway from Vermilion River to Schooner Bayou, La., has been superseded for most of its length by the project "Gulf Intracoastal Waterway (New Orleans District)." The River and Harbor Act approved July 24, 1946 (S. Doc. 231, 79th Cong., 2d sess.), authorized the incorporation of the existing project "Inland Waterway from Franklin, La., to the Mermen- tau River," west of Vermilion Bay, in the modified Flood Control, General, project "Mermentau River, La." Under ordinary conditions the mean range of tides is about 10 inches and the extreme range about 14 inches. A severe storm may cause a high tide of from 6 to 9 feet. The estimate of cost for new work (revised in 1950) is $125,000. The average annual maintenance cost during the past 5 years was $1,995. Data regarding the lock are as follows:

The Mississippi River between Baton Rouge and the Gulf of Mexico flows in a general southeasterly direction through the southeastern portion of the State of Louisiana. At the Head of Passes, 233.1 miles below the Louisiana Highway Commission bridge at Baton Rouge, the river is broken up into 3 main passes: Southwest Pass, South Pass, and Pass a Loutre, 2 of which, Southwest Pass and South Pass, are improved under the existing project. The distances from Head of Passes to the mouths of Southwest and South Passes are 20.1 miles and 13.5 miles, respectively. The mouth of Southwest Pass is 141 miles west of Mobile, Ala., and 349 miles east of Galveston, Tex. The RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 565 mouth of South Pass is 18.5 miles northeast of the mouth of Southwest Pass. (See U. S.

The estimate of cost for new work is $34,900,000 (July 1959). The average annual maintenance cost during the past 5 years was $1,712,317. Local cooperation. None required, except for modification of project in connection with Mississippi River to Gulf Outlet, which will be reported separately. Terminal facilities. Some 100 piers, wharves, or docks serve the Port of New Orleans. Practically all wharves on the east or left bank parallel the riverbank forming nearly a continuous covered quay about 10 miles long. A foreign trade zone is located in the Port of New Orleans. Public wharves controlled by the Board of Commissioners of the Port of New Orleans (the Dock Board) cover 62 percent of the improved waterfront. The board also controls the terminal facilities on the Inner Harbor navigation canal (the Industrial Canal) which connects the Mississippi River with Lake Pontchar- train and turning basin (1,000 by 1,000 feet). Since April 1, 1944, the portion of the Inner Harbor navigation canal from the Mississippi River to its intersection with the New Orleans-Rigo- lets section of the Gulf Intracoastal Waterway, exclusive of terminal facilities, but inclusive of the lock and the bridges at St. Claude Avenue and at Florida Avenue, has been under lease to the United States and is now operated by the United States on a toll-free basis, 24 hours per day. From the turning basin to the river the canal has a controlling depth of 30 feet. A quay wharf of reinforced concrete, 265 feet wide by 2,400 feet long, owned by the Dock Board is located on the west bank of the canal. All public port facilities are served by paved roadways (generally city streets) and by the Public Belt Railroad, municipally owned and operated, which connects with all 12 trunk lines entering New Orleans. The existing terminal facilities include a shipside grain eleva- tor, general cargo and cotton wharves, fruit landings, bunkering facilities, terminal warehouses, railroad terminals, marine railways, and drydocks. They are considered adequate for present commerce. (For further details see Port Series No. 20, "The Port of New Orleans, La." 1947.) Modern terminal facilities were installed by the city of Baton Rouge in 1926. A reinforced concrete dock for deep-sea vessels, 308 feet in length, has covered shed area of approximately 20,000 square feet and is equipped with a 12-ton locomotive crane. At- tached to the downstream end of the wharf is a floating wharf boat 231 by 401/2 feet, of 2,000-ton capacity. The facilities are 568 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 served by a transfer boat and municipal terminal, having a capacity of 40 cars per day. Private terminals for handling oil and other products are located at points on both sides of the river between New Orleans and Baton Rouge. The facilities are considered adequate for the 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 by the president, Mississippi River Commission and Port Series No. 19, Vol. 1, "Port St. Joe, Fla., Pensacola, Fla., Baton Rouge, La., Panama City, Fla., Pascagoula, Miss., Lake Charles, La., Gulf- port, Miss.," revised 1957.) Operations and results during fiscal year. Hired-labor forces are preparing design memorandum, which is scheduled for completion on August 31, 1959, and submitted for approval on May 22, 1959, preliminary plans and specifications for contraction work between miles 2 to 3, which work is scheduled to be advertised about November 1, 1959. The cost of this new work was $76,684. Maintenance work performed on the project was as follows: a. Baton Rouge to New Orleans: Maintenance work consisted of removing 935,198 cubic yards of material by hired labor and U.S. dredges Langfitt and A. Mackenzie at two crossings between Baton Rouge and New Orleans. The distance actually dredged was 9,600 feet, and the following work was performed: Red Eye Crossing, mile 223.0 above Head of Passes, 888,531 cubic yards, and Granada Crossing, mile 203.0 above Head of Passes, 46,667 cubic yards. Reconnaissance surveys were made of Red Eye, Medora, Gran- ada, Alhambra, Philadelphia, Bayou Goula, Belmont, and Fair- view Crossings by hired labor, as required. Costs for this work were as follows: Maintenance by hired labor: Dredging ---- $181,291 Surveys- - - -- 12,904

The distance actually dredged was 50,472 feet and the following work was performed: On November 17, 1947, contract was entered into with the Board of Commissioners of the Port of New Orleans for a more efficient and expeditious use of dredges to provide navigable depths in the project channel in the port of New Orleans, and within the 100-foot limit along the left bank wharves. On No- vember 17, 1957, a supplemental agreement extended the contract for a period of 5 years. During the fiscal year under this reciprocal agreement 98,520 cubic yards were removed by leased dredge Pontchartrainfrom within the 100-foot line and 39,355 cubic yards were removed by the Board of Commissioners outside the 100-foot line. River traffic signal lights in the vicinity of Westwego, La., Gretna, La., and Governor Nicholls Street in New Orleans, to govern the movement of vessels during flood stages on the Mis- sissippi River in the vicinity of Algiers Point, port of New Or- leans, were in operation from July 27 to August 17, 1958.

The total costs for the fiscal year were $1,731,712, of which $76,684 was for new work and $1,655,028 was for maintenance. Condition at end of fiscal year. The existing project is 74 (revised) percent complete, exclusive of the Mississippi River- Gulf outlet. a. Baton Rouge to New Orleans, New Orleans Harbor, and New Orleans to Head of Passes: This portion of the project was completed in 1940 and maintenance dredging is required at river crossings above New Orleans and in the New Orleans Harbor. Minor deficiencies in project dimensions at the lower end of Du- maine Street and Governor Nicholls Street wharves in the New Orleans Harbor were not corrected because of the presence of revetment mattresses at these points. Existing depths opposite these locations are adequate for present and anticipated future commerce. The normal width of channel between 35-foot contours within the limits of the port of New Orleans varies from 1,600 to 2,400 feet. Thalweg depths exceed 100 feet. Shoals along edges of the channel which develop at various points during high-river stages, make dredging necessary as the river stages fall, to maintain project depths to wharves along the east bank. Dredging by leased dredge was in progress in the New Orleans Harbor and by hired labor and U.S. dredge Langfitt at Red Eye Crossing at end of fiscal year. A natural channel of project dimensions or greater was available throughout the remainder of this portion of the project. b. Southwest Pass: Deepening of the pass and bar channel from 35 to 40 feet, mean low Gulf, as approved by act of March 2, 1945, is yet to be performed. Model and prototype studies are complete. The east and west jetties require additional stone placed in low sections in the jetty system and this restoration because of settlement will have to be resumed in fiscal year 1960. Replacement of approximately 896 feet of concrete capping on west jetty, Southwest Pass, that was dislodged and toppled from the jetty by strong winds and wave action of November 18, 1957, is scheduled for fiscal year 1960. The east and west headland spur dikes and various permeable pile dikes in the Southwest Pass are in effective operating condition. Preliminary plans and specifications for contraction work between miles 2 to 3, Southwest Pass, were submitted for approval on May 22. This work is scheduled to be advertised on or about November 1, 1959. Wave-wash erosion continued in that sector of Southwest Pass above mile 12 (below Head of Passes). At several areas where the narrow batture ridge along the pass is no longer present, there is communicating flow between the pass channel and adjacent open marsh areas when the low banks are submerged at high tide and high river stages. In fiscal year 1961, it is planned to initiate work over and above the routine maintenance of the permeable pile dike struc- 572 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 tures and the outlets. This will involve rewrapping, screening, and tying the structures into the existing banks plus construction of additional spur dikes to build up the banks of Southwest Pass. Also, the program will include strengthening of all outlets of the pass with stone where necessary to fully protect the outlets from further damage by erosion from high river stages. To increase bank stability and lessen overbank flow, a hydraulic fill should be placed on the existing land areas to build them up on the bay sides. For last complete report on the existing works of this pass, see pages 545 and 546 of the Annual Report of 1958. Channel conditions on June 30, 1959, were as follows:

1 This width at mile 17.8 in lower jetty channel. c. South Pass: A good channel, though narrow in width in vicinity mile 13.2 BHP, was available throughout the length of the pass during the fiscal year with dredging required only on the bar. Repairs were made by hired labor to outlet 7.9 west. Repairs to outlet 10.0 west, now under contract, should com- mence in early fiscal year 1960. The condition of the banks and outlets in South Pass are similar to those described in the South- west Pass portion in b above. Settlement of the jetties will require some restoration and all outlets should be reinforced with stone to prevent further erosion.

5. MISSISSIPPI RIVER-GULF OUTLET, LA.

Location. The work covered by this improvement is located in the State of Louisiana and extends from the existing Inner Harbor Navigation Canal at a point 7,500 feet north of the existing lock and approximately 11,000 feet from the Mississippi River, to a turning basin south of Micheaud, La., and then as a land and water cut from the turning basin south of Micheaud, La., southeasterly to and along the south shore of Lake Borgne and through the marshes to and through Chandeleur Sound to the 38-foot contour in the Gulf of Mexico. (See U.S. Coast and Geodetic Survey Charts Nos. 1115, 1116, 1267, 1268, 1269, 1270, and 1271.) Existing project. This improvement provides for a seaway canal, 36 feet deep and 500 feet wide, extending 76 miles as a land and water cut from Micheaud southeasterly to and along the south shore of Lake Borgne, and across Chandeleur Sound to Chandeleur Island and increasing gradually to a width of 600 feet and depth of 38 feet in the Gulf of Mexico, with protective jetties at the entrance, a permanent retention dike through Chande- leur Sound, and a wing dike along the islands as required. It also provides for an inner tidewater harbor consisting of a 1,000- by 2,000-foot turning basin 36 feet deep at the landward end of the seaway canal, and a connecting channel 36 feet deep and 500 feet wide extending westerly along the Gulf Intracoastal Water- way from the turning basin to the Industrial Canal, including construction of a suitable highway bridge with approaches to carry Louisiana State Highway 47 (formerly 61) over the channel. The plan further provides for the future construction of a channel and lock at Meraux to furnish an additional connection between the tidewater harbor and the Mississippi River. The estimate of cost for new work (July 1959) is $106,000,000, Federal, and $2,300,000, non-Federal. In addition the U.S. Coast Guard is to provide navigation aids at an estimated cost of $490,000. This improvement was authorized by the River and Harbor Act of March 29, 1956 (Public Law 455, 84th Cong., 2d sess.). The latest published map is in the project document (H. Doc. 245, 82d Cong., 1st sess.). Local cooperation. Local interests are required to: (a) Fur- nish free of cost to the United States all lands, easements, rights- of-way, and spoil-disposal areas for the initial construction, and when and as required for subsequent mainternance; (b) accept ownership of the highway bridge and approaches upon completion of construction, together with maintenance, operation, and future replacement or alteration as may be required; (c) provide and maintain any other bridges required over the waterway, and 574 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 accomplish all necessary utility and other highway relocations and alterations and the maintenance thereof; (d) construct, maintain, and operate terminal facilities commensurate with requirements of the expanded port; and (e) hold and save the United States free from all claims for damages due to construction, maintenance, and operation of the project. Assurances furnished by the Board of Commissioners of the Port of New Orleans have been approved by the Chief of Engi- neers and accepted on behalf of the United States. Right-of-way requirements from Inner Harbor navigation canal to Bayou Yscloskey have been finalized and the local agency has been requested to make these rights-of-way available. Right-of-way requirements beyond Bayou Yscloskey have not yet been requested. The local agency has furnished an acceptable right-of- entry for construction of reaches from Inner Harbor navigation canal to Bayou Yscloskey. The method of conveyance of title proposed by the port commission has been approved by the Chief of Engineers. Operations and results during fiscal year. Hired-labor forces carried on soil and geological studies, including borings, noncooperative stream gaging, engineering and design, current direction and velocity studies and gage observations, conducted real estate activities, and prepared plans and specifications, all at a cost of $217,681. Tools and equipment in the amount of $6,928 were purchased for the project use. Hired-labor forces constructed the foundation for the project's temporary field office in the vicinity of Paris Road and Gulf Intracoastal Waterway during the period September 22 to Octo- ber 24, 1958, at a cost of $14,461. A prefabricated metal office building, 36- by 20-feet, was furnished and erected on this foundation by contract during the period January 6 to February 25, 1959, at a cost of $4,765. Fish and wildlife studies were made by the U.S. Fish and Wild Life Service and general alinement studies of Chandeleur Sound were made by the Beach Erosion Board. The costs for these studies were $1,380. Work accomplished by the Waterways Experiment Station in previous fiscal year was overestimated in the amount of $123. Construction of the first segment of the Mississippi River-Gulf Outlet from station 0+00, at confluence of the Inner Harbor navigation canal and the Gulf Intracoastal Waterway, to station 130+00, Orleans Parish, initiated under continuing contract in previous fiscal year, was completed on December 29, 1959.

6. BARATARIA BAY WATERWAY, LA. Location. This waterway is in Jefferson Parish, La., and extends about 37 miles in a general southerly direction from the junction of the Gulf Intracoastal Waterway and Bayou Barataria near Lafitte Post Office. From its origin it extends southerly through Bayou Barataria, Bayou Dupont, a landcut (known as Dupre Cutoff) through marsh area, Bayou Cutler, Bayou St. Denis, and Barataria Bay to the east end of Bayou Rigaud. At its southerly terminus it also connects with Barataria Pass and through that pass with the Gulf of Mexico. (See U.S. Coast and Geodetic Survey charts Nos. 1050, 1116, and 1237, U.S. Geo- logical Survey maps Barataria, Bay Dogris, Wilkinson Bay, and Barataria Pass.) Previous project. The previous project was adopted by the River and Harbor Act of March 2, 1919 (H. Doc. 200, 65th Cong., 1st sess.). For further details, see pages 974 and 975 of the Annual Report for 1950. Existing project. This provides for a channel approximately 37 miles long with a 12-foot depth and 125-foot width from its beginning at the Gulf Intracoastal Waterway to Grand Isle, La., following the route of the previous project to mile 15.5 in Bayou St. Denis; thence by a relocated channel along the western shore of Barataria Bay and through Barataria Pass to the 12-foot depth contour in the Gulf of Mexico, with an extension of the project to include the westerly 3.2 miles of Bayou Rigaud. Under ordinary conditions the mean range of tide is 6 and 30 inches, respectively. In the coastal area, hurricanes have driven Gulf waters over the marshlands to an elevation of over 6 feet. The estimate of cost for new work (July 1959) is $1,680,000, Federal, and $590,000, non-Federal. In addition the U.S. Coast Guard is to provide navigation aids at a cost of $50,000. The existing project was adopted by the River and Harbor Act of July 3, 1958 (H. Doc. 82, 85th Cong., 1st sess.). The latest published map is in that document. Local cooperation. Local interests are required to: (a) Pro- vide without cost to the United States all lands, easements, rights- RIVERS AND HARBORS-NEW ORLEANS, LA., DISTRICT 577 of-way, and spoil-disposal areas necessary for the construction of the project and for subsequent maintenance, when and as required; (b) accomplish and maintain without cost to the United States all alterations to pipelines, cables, and any other facilities necessary for the construction of the project; and (c) hold and save the United States free from damages due to construction and maintenance of the project. The Jefferson Parish Council was requested on November 20, 1958, to furnish the assurances of local cooperation required by Public Law 500, July 3, 1958. Representatives of Jefferson Par- ish have held joint meetings with Louisiana Department of Public Works to determine the cost to Jefferson Parish for its participation in the project. The Department of Public Works was requested by the parish to estimate right-of-way cost based on actual right-of-way requirements by the U.S. Army Engineers. Right-of-way maps are to be delivered to Jefferson Parish on July 15, 1959. Assurances will not be given until the parish can estimate its cost for furnishing rights-of-way and guarantee of title to the easements. Terminal facilities. Six privately owned wharves at Lafitte; 3 privately owned facilities at Grand Isle; and the wharfage in Bayou Rigaud at Grand Isle constructed by the shrimping indus- try are available to all boats without charge. About 7 miles below Lafitte there is an extensive oil terminal for transferring the production of the 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.

Keystone lock was operated throughout the fiscal year, and the lock, dam, structure, and grounds were maintained, as necessary, with costs of $18,309. The total cost for the fiscal year was $94,285, of which $75,976 was for maintenance and $18,309 for operating and care. Condition at end of fiscal year. The existing project is approximately 66 percent complete. Keystone lock and dam was completed in 1913. The dredging and snagging done in 1916 completed that part of the existing project for the 6- by 50-foot channel from Arnaudville to Key- stone lock. The contract dredging done in 1918-20 completed that part of the previous project for a 6- by 50-foot channel from Keystone lock to mile 39.7 above the mouth. The 8- by 80-foot channel from New Iberia to the mouth is 98 percent complete. From the mouth to mile 5.8 a channel 8 by 80 feet, or greater, already existed, and a new channel has been excavated, 8 by 80 feet, from this point to mile 50.06, about 3.65 miles below New Iberia, and 8 by 60 feet from this point to New Iberia. Keystone lock is in good condition and the pool level was raised by 1.5 feet above the dam by contract during the period September 19, 1956, to March 27, 1957. The controlling depths, mean low gulf, were: (Feb. 1959), mile 0 to East Calumet approach, east end, 5 feet; to Wax Lake Out- let (200-foot shoal), 3.5 feet; to mile 6.5, 4 feet; to Franklin, La., 6 feet; to mile 22, 7 feet; to Charenton Canal, 6 feet; (July 1958), to mile 37, 5.5 feet; to mile 39, 5 feet; to mile 40, 3.5 feet; to mile 43, 5 feet; to mile 55, 3.5 feet; to mile 60 (Loreau- ville Canal), 3 feet; to mile 69, 5 feet; to mile 72 (Keystone lock), 4 feet; (May 1959), to mile 75, 7.5 feet; to mile 85, 7 feet; to mile 99.5, 6.5 feet; and to mile 106, 5 feet.

8. MERMENTAU RIVER, LA. Location. The work covered by this project is located 35 to 70 miles southeast of Lake Charles, La., along the lower Mermentau River below Grand Lake, mile 25, to the Gulf of Mexico; the In- land Waterway from Vermilion Bay to White Lake, White Lake to Grand Lake, and from Schooner Bayou to the Intracoastal Waterway-Gulf section (Schooner Bayou cutoff); the North Prong of Schooner Bayou; and the waterway from White Lake to Pecan Island, La., an artificial canal, extending from the 5-foot- depth contour in White Lake, almost due south for a distance of approximately 1.8 miles to Pecan Island. (See U. S. Coast and Geodetic Survey Charts Nos. 1277 and 1278, and U. S. Geological Survey maps.) Previous project. Authorized by Flood Control Act of August 18, 1941. For further details, see page 1034 of Annual Report for 1946. Existing project. The plan of improvement covers flood control, navigation, irrigation, and salinity control in the coastal marsh of the lower Mermentau River Basin and provides for channel enlargement of the lower Mermentau River below Grand Lake, mile 25, to a minimum section of 3,000 square feet below mean low Gulf level for discharge of floodflows; construction of a sector gated control structure at Catfish Point, mile 24 above mouth of Mermentau River, for discharge of flood flows and control of tidal flows and salt-water intrusion in the Mermentau River; channel enlargement and realinement of the Inland Water- way from Vermilion Bay to White Lake, 12.04 miles, and from White Lake to Grand Lake, 6.14 miles, to a minimum section of 3,000 square feet below mean low Gulf level or interflow between lakes and discharge of flood flows; construction of a sector gated control structure in the enlarged channel immediately north of the abandoned Schooner Bayou lock reservation for discharge of floodflows and control of tidal flows and salt-water intrusion; channel enlargement of North Prong of Schooner Bayou and Schooner Bayou cutoff, 6.69 miles, to 6 by 60 feet, mean low Gulf level, for navigation purposes; and maintenance of the existing 5- by 40-foot, mean low Gulf level, waterway from White Lake to Pecan Island, La., 1.8 miles long, for navigation. In addition, the project provides for the incorporation of that section of the project, "Inland Waterway from Franklin, La., to Mermentau River," west of Vermilion Bay, a waterway that included the Schooner Bayou lock. The project was reclassified as an "Operation and Maintenance, General" project under the category, "Navigation (Locks, Dams, Reservoirs, and Canals) " by authority by the Office, Chief of En- gineers, in first indorsement April 23, 1956, on letter of the divi- 582 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 sion engineer, Lower Mississippi Valley Division, March 6, 1956, subject: "Classification of the Mermentau River and Bayou Teche and Vermilion River, Operation and Maintenance, General Projects." Because of the failure of both east and west gates, Schooner Bayou lock has been closed by a dike across the east approach channel and traffic has been routed through the new control structure. Under ordinary conditions the mean range of tide on the Mermentau River near the mouth is 1.6 feet and near the head about 3 inches. The variation of the water surface near the mouth may be as much as 7 or 8 feet, due to hurricanes on the Gulf, and near the head from 8 to 12 feet, due to freshets. The cost of new work completed in 1956 was $4,631,910. The average annual maintenance cost during the past 5 years was $91,093. The existing project was authorized by the following:

Schooner Bayou and Catfish Point control structures were operated as required during the fiscal year to conserve fresh water by maintenance of normal lake stages and to prevent uncontrolled tidal inflow during the rice irrigation season; to release promptly flood waters during abnormal stages; and to limit minimum stages in the interest of navigation. The costs were $26,568 and $39,184 for operation of Schooner Bayou and Catfish Point control structures. During the period July 23 to November 12, 1958, a residence and hurricane shelter, consisting of a timber frame building on foundation piling with asbestos siding, was erected at Catfish Point control structure by contract at a cost of $46,943. The total cost for the fiscal year was $137,287, of which $71,536 was fordmaintenance and $65,751 was for operating and care. Condition at end of fiscal year. Construction of the project commenced April 21, 1947, and was completed July 10, 1952. New work dredging on the existing project was accomplished during the period April 21, 1947, to June 21, 1952. Catfish Point control structure was constructed during the period November 6, 1948, to August 16, 1951. The reservation comprises 9.7 acres. Schooner Bayou lock and control structures: Schooner Bayou lock and dam were completed in 1913 and 1914, respectively, and the lockmaster's house in 1917. The lock was closed to navigation May 7, 1951, and abandoned by authority of the Chief of Engineers on October 9, 1951. Permanent closure of the lock channel and tie-in dikes was completed on September 22, 1951. Construction of the control structure and dikes was accomplished during the period August 8, 1949, to May 22, 1951. The reservation comprises 6.9 acres. The controlling depths, mean low gulf, were: (April 1958) Gulf Intracoastal Waterway to Grand Lake, 5.5 feet; to mile 30, 2 feet; to Catfish Point control structure, 2.5 feet; through the control structure, 8 feet; to upper Mud Lake, 8 feet; through upper Mud Lake, 5.5 feet; to Grand Chenier, 6.5 feet; to lower Mud, Lake, 7.5 feet; through lower Mud Lake, 4.5 feet; to mile 0, 8.5 feet, over bar, 5 feet.

9. CALCASIEU RIVER AND PASS, LA. Location. Calcasieu River has its source in southwestern Louisiana, and flows in a general southerly direction to the Gulf of Mexico. About 25 miles from the Gulf it debouches into Cal- casieu Lake, which lake is about 18 miles long. The connection between the lake and the Gulf, about 7 miles long, is known as Calcasieu Pass. (See U. S. Coast and Geodetic Survey Charts Nos. 591 and 592; U. S. Geological Survey maps, Edna, Thomp- son Bluff, Hecker, Moss Bluff, Lake Charles, West Lake, Moss Lake, Hackberry, Sweet Lake, Brown's Lake, Holly Beach, Grand Bayou, and Cameron quadrangles; and Corps of Engineers navigation maps of Intracoastal Waterway and Atchafalaya River system.) Previous projects. The original project for this improvement was adopted by the River and Harbor Act of June 10, 1872. Ap- propriations were made by the River and Harbor Acts of March 3, 1881, August 2, 1882, July 5, 1884, and August 11, 1888. The project was modified by the River and Harbor Acts of September 19, 1890, July 13, 1892, and September 22, 1922. For further details, see Annual Report for 1936, page 719, and Annual Re- port for 1938, page 819. Existing project. This provides for a channel 35 feet deep and 250 feet wide (49.5 miles long) from the wharves of the Lake Charles Harbor and Terminal District by way of Calcasieu River, including Clooney Island Loop, to the head of Choupique Cutoff; thence by a land-and-water cut along the west shore of Calcasieu Lake; thence to and through Calcasieu Pass by a designated route to the Gulf of Mexico, subject to such change in alinement as is approved by the Chief of Engineers; the reconstruction and extension of the existing jetties initially to the seaward end of the east jetty, and further extension to the 15-foot depth contour The existing project was authorized by the following:

Total length of improvement is 102.1 miles. Under ordinary conditions, the mean range of tide is 10 inches at the mouth, diminishing to zero at Phillips Bluff, the extreme range being 14 inches and zero, respectively. The estimate of cost for new work, including $5,551,000 for the extension of the jetties to the 15-foot depth contour (revised in 1956), is $14,399,800. The average annual maintenance cost during the past 5 years was $376,253. Local cooperation. Fully complied with except for furnishing title evidence covering three tracts for which attorney's title opinions were furnished but which have now been determined to be inadequate. Under date of January 5, 1922, a permit was granted by the Assistant Secretary of War to the police jury of Calcasieu Parish to enlarge this river where necessary between Lake Charles and the eastern end of the Calcasieu-Sabine section of the Intra- coastal Waterway to a depth of 30 feet over a bottom width of 125 feet. Terminal facilities. Terminal facilities at the Port of Lake Charles are owned by the Lake Charles Harbor and Terminal Dis- trict and operated by a board of commissioners. In addition to the municipally owned terminals, there are several privately owned and operated wharf structures located on the existing ship channel. (For further details, see Port Series No. 19, vol. 1, "Port St. Joe, Fla., Pensacola, Fla., Baton Rouge, La., Panama City, Fla., Pascagoula, Miss., Lake Charles, La., Gulfport, Miss." revised 1957, and Folio of Navigation Maps, Intracoastal Water- way, New Orleans to Port Arthur, 1958, published by Missis- sippi River Commission, Corps of Engineers, U.S. Army.) Operations and results during fiscal year. Real estate activities, investigations, studies, surveys, and aerial photography were carried on by hired labor at a cost of $29,493. Funds in the amount of $472 were transferred to the U.S. Geological Survey as the project's pro rata share of costs for operation of the cooperative stream-gaging program. During the period January 21 to 28, 1959, approximately 966,123 cubic yards of shoaled material were removed by the U.S. Dredge Langfitt in restoring the bar channel of Calcasieu River and Pass, La., at a cost of $31,533. The main channel of Calcasieu River between miles 21.5 to 15.4 was restored to project dimensions during the period Sep- tember 18 to December 19, 1958, when the contract dredge Diesel removed a total of 2,619,573 cubic yards of shoaled material. The cost of this contract dredging was $431,316. A continuing contract was awarded on June 26, 1959, for removal of shoaling in Calcasieu River and Pass, between miles 25.2 to 30.0 and 34.0 to 35.3, Clooney Island Loop. Work under the contract has not been initiated. 586 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 The total cost for the fiscal year was $492,814 for maintenance. Condition at end of fiscal year. The project as modified is 54 percent complete, including extension of the jetties seaward to the 15-foot depth contour; if and when found necessary. Dredging under the existing project, prior to the modifications adopted by the River and Harbor Acts of March 2, 1945, and July 24, 1946, was completed in 1941, and the 30- by 250-foot ship channel was formally opened to deep-draft traffic on July 12, 1941. Work on the modified project of deepening the 250-foot channel to 35 feet from Lake Charles to the 37-foot depth contour in the Gulf of Mexico was initiated on September 7, 1948, and completed on April 25, 1953.

The Calcasieu Pass jetties, initiated under the previous project and completed in May 1942, extend to the 10-foot depth contour and are in good condition. The east jetty, approximately 8,620 feet long, has been built to approximately 6 feet above mean low Gulf, and extends seaward from the existing Gulf shoreline a distance of 6,820 feet. The west jetty, 8,050 feet long, has been built to approximately 4 feet above mean low Gulf and extends seaward from the existing Gulf shoreline a distance of 6,795 feet. The jetty structure is considered complete unless at a later date it is found necessary to extend the jetties seaward to the 15-foot depth contour, as provided for in the project.

10. EXPANDED PROJECT FOR AQUATIC PLANT CONTROL Location. Lakes and streams in the State of Louisiana. Existing project. This provides for the control and progres- sive eradication of the water hyacinth, alligatorweed, and other obnoxious aquatic plant growths from the navigable waters, tributary streams, connecting channels, and other allied waters in the States of North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, and Texas, in the combined interests of navigation, flood control, drainage, agriculture, fish and wildlife conservation, public health, and related purposes, including continued research for development of the most effective and economic control measures. The estimate of cost (April 1959) for the expanded program in the New Orleans District, is $5,040,000, of which 70 percent, or $3,530,000 shall be borne by the United States and 30 percent, or $1,510,000, by local interests. The existing project was authorized by the River and Harbor Act of July 3, 1958 (H. Doc. 37, 85th Cong., 1st sess.). The latest published maps are in the project document. Local cooperation. Local interests are required to: (a) Hold and save the United States free from claims that may occur from such operations; and (b) participate in the project to the extent 3f 30 percent of the cost of the additional program. The State of Louisiana, Department of Public Works, and the Louisiana Wild Life and Fisheries Commission furnished a joint assurance of local cooperation, which was approved on April 29 and accepted on May 4, 1959. Under the provisions of a continuing contract for approximately 5 years, the local agencies will perform work in kind approximating 30 percent of the cost of the additional program. 588 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959

The average annual maintenance cost during the past 5 years was $229,274. Local cooperation. None required. Terminal facilities. The terminal facilities of the various streams from which hyacinths were removed are described in the report for the improvement of these streams. Operations and results during fiscal year. A well-balanced combination of mechanical and chemical methods of destruction was undertaken to take the maximum advantages of funds available. Economics in effect resulted in curtailed operations and limited the work to only those main waterways over which the major portion of navigation moves. Preventive maintenance work in secondary streams and feeder areas was sharply curtailed with a resultant increase in vegetation in these areas. Some momentary inconvenience was caused at times when this vegetation disgorged into the main streams after a heavy squall. Feeder areas previously freed of the hyacinth and placed on a patrol maintenance basis have now become heavily infested with alligator weed which has not proved susceptible to chemical treatment. A total of 21,924,799 square yards (4,529.9 acres) of vegetation was destroyed by chemicals and 1,415,500 square yards (292.5 acres) by machinery in Bayou Black, Lake Cataouatche and feeder streams, streams of the Lake des Allemands Basin, the Lake Dauterive area, the Intracoastal Waterway, Bayou Lafourche, streams of the Lake Maurepas Basin, the Bayou Penchant-Bayou Copassaw area, the Plaquemine Waterway, and in Bayous Teche, Misere, and Lacassine. Operations were conducted on a curtailed schedule with the work being confined to the main navigational channels on a re- curring basis. Some handicap to navigation resulted. No permanent results can be expected on this basis as work must be accomplished in feeder areas and secondary streams if complete reinfestation of the main channels is to be avoided. Operations were conducted only in areas where severe hardship would have resulted if the work had not been undertaken. SThe total cost for the fiscal year was $253,228 for maintenance. Condition at end of fiscal year. From 1900 to 1902 a boat with suitable machinery for destroying the hyacinth by crushing was operated. From that time until 1937 hyacinths were destroyed through the use of a solution of arsenic and caustic soda which was sprayed on the vegetation, removal by hand crews and controlled in their movements by means of booms and barricades. The use of arsenic has been discontinued and hand removal has been supplanted by use of mechanical equipment in conjunction 590 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 with the chemical spray (2,4-dichlorophenoxyacetic acid). Pres- ent methods of control are by means of mechanical rotary saw- type destroyers, chemical treatment, and the use of booms and barricades. Excellent results are being obtained on water hyacinths by these methods. The total cost to the end of the fiscal year was $5,128,450 for maintenance.

14. RED RIVER BELOW DENISON DAM, NEW ORLEANS DISTRICT Location. The work covered by this project is located on the Red River and its tributaries below Denison Dam, in Oklahoma, Arkansas, Texas, and Louisiana. (See U. S. Geological Survey State maps and folio "Maps of Red River"-1958 edition.) Existing project. The Flood Control Act approved July 24, 1946, approved the general plan for flood control on Red River below Denison Dam, Tex. and Okla., which provides for the construction of six flood-control reservoirs in combination with existing or authorized Federal and non-Federal levee improvements, modified as required, and channel stabilization at locations where levee setbacks are impossible or uneconomical. This act further authorized the incorporation of the several separate existing projects for flood control along the Red River below Denison, above the jurisdiction of the Mississippi River Commission, into this project. By Public Law 780, 83d Congress, 2d session, September 3, 1954, as amended by Public Law 218, 84th Congress, 1st session, August 3, 1955, the plan of improvement was amended to include additional projects as indicated in the following lists of the reservoirs and local protection works considered in the general flood-control plan for the Red River below Denison Dam, and the existing flood-control projects incorporated into the project in the New Orleans District:

15. MCKINNEY BAYOU AND BARKMAN CREEK, TEX., AND ARK. Location. McKinney Bayou rises in the northeastern part of Bowie County, Tex., and flows easterly an original distance of 76 miles, passing 8 miles north of Texarkana, Tex., and entering Red River at mile 386. Flows from the upper 20 miles of this stream were diverted into Red River at mile 494.3 by levee and channel construction across McKinney Bayou below the mouth of Barkman Creek, a right-bank tributary, which rises in the hills to the south. Existing project. The plan of improvement provides for channel clearing, realinement, and enlargement of McKinney Bayou below mile 50; the enlargement of the existing hillside floodway levee between miles 12 and 14 and the extension thereof upstream to the mouth of Red Chute, mile 27, thence up Red Chute for 2 miles; the construction of a new levee and closure of high water outlets between miles 31 and 43, and the construction of appurtenant drainage works including a floodgate; all of which would reduce flood damage on approximately 26,000 acres of cropland. It also provides for channel clearing, realinement, and enlargement, along Barkman Creek below the mouth of Jones Creek, mile 11, and along the canal for its diversion into Red 594 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 River at mile 494, with construction of a supplementary new floodway levee and appurtenant drainage works which would reduce flood damage on approximately 4,000 acres of cropland. The estimate of cost for new work (July 1959) is $1,390,000 Federal, and $432,000 non-Federal. The existing project was authorized by the Flood Control Act approved August 3, 1955 (H. Doc. 488, 83d Cong., 2d sess.). The latest published map is in the project document. Local cooperation. Local interests are to provide without cost to the United States all lands, easements, and rights-of-way, and make alterations and relocations of highways and related facilities, and utilities except railroads necessary for the construction; hold and save the United States free from damages due to the construction; and maintain and operate all works after completion, and preserve channel capacities by preventing encroachment, in accordance with regulations prescribed by the Secretary of the Army. Assurances furnished by Miller County Improvement and Drainage District and approved by the division engineer were accepted by the district engineer on June 6, 1959. These assurances cover only that portion of the project which lies in Arkan- sas. Negotiations are continuing with Bowie County Levee Dis- trict No. 1 for assurances for proposed improvement of McKinney Bayou in Texas. The levee district is being reorganized and members expect to meet shortly to name a new chairman, when assurances for McKinney Bayou are expected to be adopted. No local agency has yet agreed to furnish assurances for Barkman Creek improvement. There is disagreement among local landowners as to the method of improving Barkman Creek and no local group can reach agreement about assuming local cooperation responsibilities. For the purpose of assurances, McKinney Bayou is considered separately. Miller County Improvement and Drainage District has acquired and made available rights-of-way for the first reach on McKinney Bayou from mile 0.0 to mile 16.8. Rights-of-way for the next reach have not been requested. Operations and results during fiscal year. Hired-labor forces carried on surveys, studies, noncooperative stream gaging, and real estate activities; completed plans and specifications for McKinney Bayou channel improvement and appurtenant work between miles 0.0 to 16.8; initiated work on plans and specifications for channel improvement of the bayou between miles 16.8 to 46.5 and for the Barkman Creek floodway levees, pertinent drainage and channel improvement, miles 0.0 to 9.4; and commenced negotiations for modification of the St. Louis Southwest- ern Railway trestle. A continuing contract was awarded on June 23, 1959, for channel excavation, clearing and snagging, levee construction, and drainage ditch excavation from mile 0.0 to mile 16.8, McKinney Bayou, Ark., and for construction of a drainage structure.

16. MANIECE BAYOU, ARK. Location. The Maniece Bayou drainage area of 88 square miles is located on the left bank of Red River in Lafayette County, Ark. 'The drainage area which is from 3 to 5 miles in width and about 25 miles in length roughly parallels the Red River. Maniece Bayou enters Red River at mile 366.5 (1950-51 mileage). Maniece Bayou, below mile 5, flows through a deterio- rated bed of an ancient Red River meander, characterized by a typical alluvial ridge on each side of the stream. The main line Red River levee ties into the right bank ridge at about mile 3.6. Atthis point the channel lies along the base of the escarpment. Above mile 8 the bayou is poorly defined and traverses a low swamp area. The inadequate outlet capacity of Maniece Bayou results in impoundment in the swamp for extended periods during the rainy season with resulting impairment of drainage on the surrounding improved lands and periodic overflow of these lands during moderate storms. Existing project. The plan of improvement provides for the diversion of Maniece Bayou through enlarged existing channels anid lan d cuts to enter Red River at mile 362.3, for snagging and clearing of the existing channel between Red River and mile 047, and for channel enlargement and realignment between miles0.47 to 8.0. The cost of constructing the project, completed in 1959, was $128,274... The existing project was authorized by the Flood Control Act approved August 3, 1955 (H. Doc. 488, 83d Cong., 2d sess.).

24. AMITE RIVER AND TRIBUTARIES, LA.

Location. The Amite River rises in southwestern Mississippi and flows south and southeasterly 170 miles to Lake Maurepas, FLOOD CONTROL-NEW ORLEANS, LA., DISTRICT 611 in southeastern Louisiana. Elevations in the basin range from sea level near Lake Maurepas to about 400 feet in the head- waters. The principal tributaries of the river are the Comite River and Bayou Manchac, which enter from the right bank at miles 54 and 35.75, respectively, and Colyell Bay from the left bank at mile 29.5. Cypress Bayou and Hurricane Creek are right bank tributaries of the Comite River. Existing project. This provides for the construction of a new channel to divert flood flow from the Amite River near French Settlement, La., to Blind River, a distance of approximately 10.6 miles, from mile 25.3 on the Amite River to mile 4.8 on Blind River, with intermittent clearing and snagging on Blind River below that point to Lake Maurepas; enlargement and realinement of Amite River from mile 25.3 to the mouth of Bayou Manchac, mile 35.75; intermittent clearing and snagging on Amite River from the mouth of Bayou Manchac to the mouth of Comite River, mile 54; a major bridge crossing of the diversion channel at State Route 22, and suitable modification of the existing highway bridge at Port Vincent; removal of channel obstructions on Bayou Manchac between its mouth and Ward Creek, mile 8.4; and channel enlargement and realinement of Comite River from its mouth to Cypress Bayou at mile 10, with suitable modification of two existing bridges. In order to prevent excess diversion of low-water flow into the diversion channel, connection with the river would be made by a 1,500-foot side channel control weir with crest at mean sea level. The estimate of cost for new work (July 1959) is $3,360,000, Federal, and $1,964,000, non-Federal, including contributed funds in the amount of $1,070,000 or equivalent work. The existing project was authorized by the Flood Control Act of August 9, 1955 (H. Doc. 419, 84th Cong., 2d sess., which also contains the latest published map.). Local cooperation. The project document states that local interests are required to (a) provide without cost to the United States all lands, easements and rights-of-way necessary for construction of the project; (b) construct at their own expense all new highway bridges and highway bridge changes, including approaches made necessary by the improvement; (c) provide at their expense all relocations or modifications to telephone and power lines, pipelines and other public utilities required by the construction; (d) maintain and operate all works after completion; (e) hold and save the United States free from all damages to the construction; (f) provide a cash contribution or its equivalent in construction work as follows: (1) for Amite River and Bayou Manchac area a contribution now estimated at $892,000, equivalent to 24.7 percent of actual construction cost; and (2) for the Comite River area a contribution now estimated 612 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959

at $67,000, equivalent to 18.6 percent of actual construction cost. All assurances of local cooperation were approved by the division engineer on January 9, 1957, and accepted by the district engineer. All rights-of-way required for the diversion channel construction have been made available by the local agencies. Advertise- ment of Amite River realinement and enlargement between miles 25.3 to 31.5 is delayed due to right-of-way difficulties. Local interests expect to give right-of-entry for this reach early in fiscal year 1960. Operations and results during fiscal year. Acquisition of rights of-way and preparation of plans and specifications were carried on by hired labor at a cost of $11,692. Funds in the amount of $1,100 were transferred to the U.S. Geological Survey for the project's pro rata share of cost for operation of the cooperative stream-gaging program. The continuing contract initiated on June 24, 1957 for construction of the Amite River diversion channel between stations 170+ 00 to 306+00 was completed on July 16, 1958, with 78,781 cubic yards removed by dredge Moreland II in completing the channel to project grade over a distance of 0.13 mile. The length of the channel constructed under the contract is 2.58 miles. The continuing contract awarded in previous fiscal year for construction of the diversion channel between stations 306+00 to 559+00 continued. The channel is 94 percent complete with 5,417,630 cubic yards removed to date and 3,175,087 cubic yards removed this fiscal year as indicated below:

To date 3.92 miles of the channel to be dredged under the contract has been completed to project grade and the remaining channel has been dredged partially. Construction of the diversion channel between stations 0+00 to 24+00 under continuing contract, was accomplished during the period July 8, 1958, to January 27, 1959, with the contractor's dragline removing 231,699 cubic yards during the period July 8 to October 22, 1958, and the subcontractor's dredge Plaquemine removing 154,366 cubic yards between November 1, 1958, to January 27, 1959, over the length of the channel, or 0.45 mile. The remaining drainage ditch was completed by dragline this fiscal year. Plans and specifications for channel enlargement and realinement of Amite River between miles 25.3 to 31.5 by the removal of approximately 2,865,000 cubic yards will be forwarded for approval on July 10 and are scheduled to be advertised on or about August 15, 1959.

2. OUACHITA AND BLACK RIVERS BELOW CAMDEN, ARK. Location. Ouachita River rises in Polk County, Ark., and flows about 600 miles in a general southeasterly and southerly direction through Arkansas and Louisiana. It is joined by the Tensas and Little Rivers at Jonesville, La., below which place it is called Black River, and enters Red River 35.5 miles above its mouth. (See El Dorado, Shreveport, Jackson, and Natchez sheets of the U. S. Army Map Service, Corps of Engineers' map of the United States, scale 1:250,000, and Moro Bay, Ingalls, Strong, Felsen- thal, Haile, Drew, Monroe, Columbia, Fort Necessity, Harrison- burg, Manifest, Tooleys, and Deer Park quadrangle maps), also folio of maps of the Ouachita-Black Rivers, Ark., and La., from Blakely Mountain Reservoir to Mississippi River including Old River and portion of Red River, scale 1:62,500. Previous projects. The project was adopted by the River and Harbor Acts of March 3, 1871, June 10, 1872, August 14, 1876, and July 5, 1884. A separate project for work in the Ouachita River between Camden and Arkadelphia was adopted by the 617 618 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959

River and Harbor Act of August 11, 1888. For further details, see page 1869 of the Annual Report for 1915, and page 900 of the Annual Report for 1938. Existing project.. This provides for a navigable depth of 61/2 feet at low water from the mouth of Black River, La., to Camden, Ark,; a distance of 351 miles, by the construction of 6 locks and dams, with necessary dredging, and for removal of logs, wrecks and overhanging trees, etc., between mouth of Black River and Arkadelphia, Ark., 417 miles, and for a channel 7 feet deep and of suitable width from the improved channel of the Ouachita River above dam No. 6 to the vicinity of the railroad bridge over Lake St. Mary, thence a canal of the same depth and 70 feet in width along the south side of the railroad embankment to high ground with a suitable turning basin near Felsenthal, a distance of 3,600 feet. The project also provides for operation and care of all locks and dams included therein.

The existing project was authorized by the following:

C/I 620 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 Floods ordinarily caused fluctuations of stage from 25 to 45 feet between high and low water. Extreme floods occasionally increase this range about 10 feet. The latest approved (1959) estimate of cost for new work is $21,700,000. The average annual maintenance cost during the past five years was $541,089. Local cooperation. Fully complied with for completed portions of the project. Total estimated costs for all requirements of local cooperation under terms of the project authorization, including required non-Federal contributions, amount to $1,440,000, based on July 1959 price levels. Terminal facilities. At Camden, Ark., there is a privately owned loading dock with a gasoline-operated crane. At Calion, Ark., there is a privately owned conveyor and dock for unloading logs. At Champagnolle Landing, Ark., there is a privately owned dock for unloading liquid sulfur and for loading or unloading petroleum. At Sterlington, La., there is a privately owned dock for loading and unloading chemicals. At West Monroe, La., there is one privately owned warehouse. Terminal facilities are being expanded as required to meet the need of barge traffic. Operations and results during fiscal year. Advance engineering and design for the modified project were continued. The revised review report on Ouachita River and tributaries with respect to Ouachita River navigation, which was submitted to higher authority February 24, 1958, was returned for further revisions and resubmitted May 18, 1959. Maintenance dredging was done in the channel of the stream at 34 locations between Camden, Ark., and the mouth of Black River. A total of 316,932 cubic yards of material was moved by the U.S. cutterhead dredge Nelson. The six locks and dams were maintained and operated throughout the fiscal year by hired labor. Cost of advance engineering and design during the fiscal year was $23,430 for new work. The total cost of maintenance was $567,711, of which $264,906 was for maintenance dredging, and $302,805 was operation and care of locks and dams. Condition at end of fiscal year. The project providing for a depth of 6.5 feet has been completed and is being maintained. New work under the modified project has not been started. The six locks and dams embraced in the existing project for slack-water improvement of the Ouachita River were completed in 1924 and provide navigation to Camden, Ark. (See table under existing project.) Construction of the canal to Felsenthal, authorized in 1937, has not been started. RIVERS AND HARBORS-VICKSBURG, MISS., DISTRICT 621 The head of navigation is Arkadelphia, Ark., to which point boats may occasionally run during high water if snags, overhanging trees, or similar obstructions do not interfere. From Janu- ary to June the gage at Monroe generally exceeds pool stage (13.3 feet), caused by the river above, and minimum depths exceeding 7 feet are usual between the mouth of Black River and Camden, Ark., a distance of 351 miles. At intervals during this period, the reading of the Camden gage exceeds 15 feet, and minimum depths of 7 feet may be expected between Camden and Arkadel- phia. During the remainder of the year the pools furnished by the six dams, with moderate dredging in Black and Ouachita Rivers, provide depths of 6.5 feet between the mouth of Black River and Camden, Ark., and depths of only a few inches may be expected between Camden and Arkadelphia, Ark. At the end of the fiscal year project depth of 6.5 feet below mean low water was available between Camden, Ark., and the mouth of Black River. The total costs to the end of the fiscal year under the existing project were $4,773,942 for new work, $5,524,017 for maintenance, and $4,248,180 for operation and care of locks and dams, totaling $14,546,139. In addition, the sum of $2,940,952 was expended between Janu- ary 25, 1913, and June 30, 1936, on the operation and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes.

4. OUACHITA RIVER AND TRIBUTARIES, ARK. AND LA. Location. Ouachita River rises in Polk County, Ark., and flows about 600 miles in a general southeasterly and southerly direction through Arkansas and Louisiana. It is joined by the Tensas and Little Rivers at Jonesville, La., below which place it is called Black River, and enters Red River 35.5 miles above its mouth. (See U. S. Geological Survey State maps; McAlester, Little Rock, El Dorado, Shreveport, Jackson, and Natchez sheets of the U. S. Army Map Service, Corps of Engineers' map of the United States, scale 1 :250,000; and Mississippi River Commission, Corps of Engineers, U. S. Army, Alluvial Valley quadrangle maps FLOOD CONTROL-VICKSBURG, MISS., DISTRICT 623 and folio of maps of the Ouachita-Black Rivers, Ark. and La., from Blakely Mountain Reservoir to Mississippi River including Old River and portion of Red River, scale 1:62,500.) The Ouachita River Basin embraces about 25,000 square miles. Headwater streams drain about 3,500 square miles of rugged terrain of the Ouachita Mountains (including some 1,500 square miles of the Ouachita National Forest). Downstream the basin comprises about 21,500 square miles of hilly uplands and broad plains. Below Riverton, La., approximately 1,490 square miles are in the Red River backwater area. Existing project. The River and Harbor Act of May 17, 1950 (S. Doc. No. 117, 81st Cong., 1st sess.), approved the general plan for flood control on Ouachita River and tributaries, Arkansas and Louisiana, which provides for the construction of one multiple-purpose and one flood-control reservoir; protection works for three localities and channel improvement at several points. This act further authorized the incorporation into the general plan of the several separate existing projects for flood control along the Ouachita River and tributaries in the basin above the lower end of the levees on the east bank of Ouachita River. The total estimated cost of the project (1959) is $88,018,823 for new work, as itemized in the following tables:

The work covered by this project is located on Caddo River (mile 8), a tributary of the Ouachita River, in a narrow, rocky gorge, in Clark and Hot Spring Counties, approximately 10 miles north of Arkadelphia, Ark. (For latest published map, see H. Doc. 117, 81st Cong., 1st sess.) Existing project. The plan of improvement provides for the construction of a multiple-purpose flood-control, power and water- supply reservoir on Caddo River as a feature of the comprehensive plan for flood control on the Ouachita River and tributaries. The reservoir will provide a gross storage capacity of 739,400 acre-feet and power installation totaling 40,000 kilowatts (two units at 20,000 kilowatts each). The water supply feature will provide 250 million gallons per day for municipal and industrial use. The latest approved (1959) estimate of first cost is $33,700,000 for new work. The project was authorized by the River and Harbor Act approved May 17, 1950 (S. Doc. 117, 81st Cong., 1st sess.), and modified for the inclusion of water-supply storage under the general authority provided by the Water Supply Act of 1958. Local cooperation. None required for the flood control and power features. For the water-supply feature, local interests are required to bear all costs of the project allocated to water supply. Not to exceed 30 percent of the total estimated cost of the project may be allocated to anticipated future demands when States or local interests give reasonable assurances that they will contract for the use of such storage within a period of time which will permit paying out the costs allocated to water supply within the life of the project. Local interests are also required to give reasonable assurances prior to initiation of construction that they will contract for all costs allocated to water supply storage in excess of 30 percent of the total estimated project cost. In addition, local interests will be required to bear the share of project costs allocated to water supply both for operation and maintenance annually and for major replacements when incurred. The Ouachita River Water District, formed by Clark County, Ark., Circuit Court order of January 28, 1959, is empowered under law of the State of Arkansas to meet the requirements of local cooperation. No progress toward fulfillment will be made until a cost allocation report is approved. 628 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959

Wolf River rises near the western edge of Tippah County, Miss., and flows generally northwesterly about 117 miles, through Shelby County, Tenn., emptying into the Mississippi River within the corporate limits of the city of Memphis, Tenn. (See Mississippi River Commission alluvial valley maps, scales 1:62,500, 1:250,000, and 1:500,000.) Previous projects. The River and Harbor Act of August 18, 1894, authorized dredging at the mouth of Wolf River as an item in the improvement of Memphis Harbor, the work being carried out under the supervision of the Mississippi River Commission. Existing project. This provides for a channel 9 feet deep at low water from its mouth to Hindman Ferry Road (5.5 miles) with bottom widths of 250 feet from the mouth to Keel Avenue (mile 1.75) and 200 feet from Keel Avenue to North Second Street Road (mile 3.5), and thence 125 feet wide from North Second Street Road to Hindman Ferry Road. The portion of the project from the river mouth up to mile 3.0 is completed and maintained. The average annual maintenance cost during the past 5 years was $118,002. The work of improvement up to mile 3.0 under the existing project was authorized September 6, 1933, by the Public Works Administration. The existing project was adopted by the River and Harbor Act approved August 30, 1935 (Rivers and Harbors Committee Docs. 26, 72d Cong., 1st sess. and 45, 74th Cong., 1st sess.) Sketch maps are printed in the project documents. Modification of the upstream portion of the authorized project between miles 3.0 and 5.5 is provided in the Mississippi River 633 634 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 and tributaries project, as amended by the Flood Control Act of 1958, subject to the receipt of assurances from local interests that they desire that flood-control improvement be constructed in lieu of the upstream navigation extension above mile 3. (See report of the Mississippi River Commission, pages 1910 and 1937. Local cooperation. The work under the existing project is subject to the condition that local interests shall furnish, free of cost to the United States, all rights-of-way required for channel enlargement and straightening, and suitable areas with retaining levees where needed for disposal of dredged material during initial construction and future maintenance as and when needed, and shall furnish assurances satisfactory to the Secretary of Army saving the United States free from damages resulting from the work. The work is also subject to the provision that no works shall be undertaken on any section of the channel through or above any bridge until such bridge has been altered in a manner satisfactory to the Secretary of Army, without cost to the United States. The conditions as pertaining to the improvement up to mile 3.0 have been complied with. Terminal facilities. There are 24 terminals in the lower 3 miles of Wolf River. Five terminals are operated by common carriers, 3 by contract carriers, and 16 are operated privately. Operations and results during fiscal year. Maintenance dredging during the fiscal year 1959 was conducted with one leased dredge, the Burlington, which moved a total of 575,709 cubic yards of material in maintaining a channel of project dimensions. The total cost for the year was $98,418. Condition at end of fiscal year. The portion of the existing project to mile 3.0 is complete and at the end of the fiscal year ample depths existed in the channel below a point 900 feet above Hall Street. Project depth at low water is maintained by dredging as required.

The plan of improvement provides for the construction of a system (eight sections) of levees, floodwalls, and bank protection, consisting of the following features: about 22,000 feet of earth levee and 2 concrete railroad floodgates along the right bank of Nonconnah Creek, extending from high ground near Tennessee Chute south of Riverside Park to high ground at Bodley Avenue east of Prospect Street; about 15,600 feet of concrete floodwall, and 31,500 feet of earth levee along the left bank of Wolf River, extending from downtown Memphis to high ground near Douglas Park; construction of 6 new pumping stations and 8 storage reservoirs with appurtenant works for the disposal of interior drainage; and the construction of a culvert under North Bellevue Boulevard near Cypress Creek for the enlargement of the Cypress Creek Reservoir. The project will provide protection, with 3 feet freeboard, for the city of Memphis and adjacent areas against a Mississippi River flood of 54.5 feet 636 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 stage, or 4.1 feet higher than the maximum flood of record, which occurred in February 1937. The project was adopted by the Flood Control Act approved August 28, 1937, and so modified by the War Department Civil Appropriation Act approved June 28, 1939, that the cost of providing pumping stations and outlet works for interior drainage shall be borne by the United States, and further amended by the Flood Control Act approved July 24, 1946, to increase the total estimated cost of the project by $1,500,000. The current (1959) estimated cost of construction, is $11,200,000. Local cooperation. General assurances given by the city of Memphis and Shelby County, Tenn., were approved by the Secre- tary of War on August 2, 1938. All rights-of-way for the project have been provided by local interests. Operations and results during the fiscal year. Work was completed on sections 1-E and 5 of the floodwall. The cost for the year was $629,645, all for new work. Condition at end of fiscal year. Except for the levee in section 5, all works have been completed and turned over to local interests for maintenance and operation. The total cost to June 30, 1959, was $11,131,119, all for new work.

See House Document 669 (76th Cong., 3d sess.) for report of Chief of Engineers dated February 27, 1940, containing a general plan for improvement of the Mississippi River between Coon Rapids Dam and the mouth of the Ohio River for purposes of navigation, power development, the control of floods, and the needs of irrigation. Terminal facilities. Most of the water terminal and transfer facilities of the district are described in volumes 1 and 4 of the 4-volume report of the Board of Engineers for Rivers and Har- bors, entitled "Survey of Terminals and Landings on the Inland Waterways of the United States". Operations and results during fiscal year. Construction works were carried on by contract and by hired labor with Government plant, weather conditions and river stages being favorable for construction during the year. Regulating works were maintained, and project dimensions of channels were secured by dredging. Construction was initiated on dam No. 27, Mississippi River, Chain of Rocks, in February 1959. 642 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 New work: Regulating works-costs incurred were $15,690 for engineering and design, and $80,456 for other distributive costs. Work by contract consisted of $108,545 for revetment and $897,163 for construction of dikes. Total costs of regulating works were $1,101,854. Dam No. 27-costs incurred were $37,792 for engineering and design, $21,280 for other distributive costs, $8,521 for acquisition of lands, and $672 for real estate management. Work by contract consisted of $38,365 for engineering and design, $300,000 for revetment, and $158 for acquisition of lands. Total costs for dam No. 27 were $406,788. Total costs for new work were $1,508,642. Maintenance: Dikes (8,065 linear ft.) and revetment (3,890 linear ft.) were repaired by U.S. plant and hired labor at a cost of $616,284. Channel dredging was performed at 43 localities, removing 3,575,349 cubic yards of material from the main channel at a cost of $915,748. The channels dredged had a combined length of 23.7 miles, an average width of 285 feet, and an average gain in depth of 3 feet. Hydrographic surveys were made covering 197.9 miles of river costing $72,865. Channel was patrolled and aids to navigation were inspected at a cost of $68,237. Other costs were: Distrib- utive costs, $20,746; flood forecasting and discharge observations, $15,137; cooperative hydroclimatic network (rain gages), $80; cooperative stream gaging (river gages), $21,909; noncooperative stream gaging (river gages), $7,838; lock No. 27 lift-gate chains, $1,461; cathodic protection lock gates, $2,878; collection of damages to Government structures, -$2,669; damage repairs, $2,253; stores, -$3,592; other credits to operation, -$4,133; inspection and reports, $1,207; and miscellaneous reports and programing, $14,438. The cost of operating and care of lock No. 27 and canal was $203,673. Costs of maintenance including operating and care were $1,954,360. Deferred maintenance: $1,963 for distributive costs. Work by contract consisted of $25,875 for painting bridges. Total deferred maintenance costs were $27,838. Total costs of maintenance for the fiscal year were $1,982,198. Condition at end of fiscal year. Construction on the existing project was initiated in 1881, and the project has been in beneficial use practically from its conception. Work under the project is about 78 percent complete. The quantities required to complete the project are estimated at 86,400 linear feet of pile dike, 93,465 linear feet of revetment, 280,000 cubic yards of rock removal, construction of rockfill dam, and minor items of work at Chain of Rocks. Dikes and revetments were in poor condition along some reaches of the river due to critical damage inflicted RIVERS AND HARBORS-ST. LOUIS, MO., DISTRICT 643 by heavy ice flows during the years 1950-51, 1957-58, and by floods in spring and summer of 1951. The channel as a whole has been greatly improved by the work that has been completed to date. Dredging is required at low stages to remove temporary shoals and maintain the required channel depths. The project dimensions of channels have generally been maintained throughout the navigation season. The navigation season formerly extended from the middle of February to the middle of December, the river being generally closed by ice the remainder of the year. However, in recent years increased demands of commerce and the use of steel-hull boats have combined to extend the navigation season throughout the year except when blocked by heavy ice or gorges. The river is generally above the 10-foot stage, St. Louis gage, for 6 months of the year, latter part of February to latter part of August, during which time project channel depths generally prevail without dredging. The mean stage of the river, St. Louis gage, was 5.48 feet for the fiscal year 1958 and 8.10 feet for the fiscal year 1959. Cost and financial statement

20. KASKASKIA RIVER, ILLINOIS Location. The Kaskaskia River rises in Champaign County, Ill., about 5 miles northwest of Urbana, in the east central part of the State. It flows in a general southwesterly direction approximately 325 miles and empties into the Mississippi River about 8 miles above Chester, Ill., or approximately 118 miles above the mouth of the Ohio River. (See Nashville and Cincin- nati sheets of map of United States published by the Army Map Service, scale 1:500,000; also U.S. Geological Survey quadrangle maps, scale 1:62,500.) Existing project. The plan of improvement provides for the construction of a dam at Carlyle and five levee projects between Carlyle and New Athens authorized by the Flood Control Act of June 28, 1938, and constructing a dam at Shelbyville, six levee projects along the river between Cowden and Vandalia, and a local protection project at New Athens, all authorized by the Flood Control Act of July 3, 1958. Under the plan, the Carlyle and Shelbyville Reservoirs would be operated as a multiple- purpose project for local and Mississippi River flood control, domestic and industrial water supply, releases in the interest of FLOOD CONTROL - ST. LOUIS, MO., DISTRICT 661 navigation on the Mississippi River, fish and wildlife conservation, and recreation. The 11 levee projects would provide protection to approximately 54,610 acres of land. In view of the inclusion of the previously authorized Carlyle Reservoir and the levees between Carlyle and New Athens in the recommended plan, the general comprehensive plan for flood-control and other purposes in the upper Mississippi River basin, approved by the Flood Control Act of June 28, 1938, was modified by deleting therefrom the Carlyle Reservoir and levees between Carlyle and New Athens. The estimated cost (1959) of construction is $40,700,000 and $18,500,000 for the Carlyle and Shelbyville Res- ervoirs, respectively, $7,590,000 for levees between Carlyle and New Athens, $5,453,00 for levees between Cowden and Vandalia, and $1,680,000 for protection of New Athens, a total of $73,923,000. Local cooperation. With reference to the construction of the 11 proposed levee districts and protection for the village of New Athens, local interests would be required to furnish all lands, easements, and rights-of-way; bear the cost of all property damage; provide necessary relocations and alterations to highways, roads, and bridges; relocate and adjust all utilities; construct drainage ditches; hold the United States free from any damage due to construction works; and maintain and operate the projects after completion. In addition, local interests would be required to contribute varying amounts which total 39.3 percent of the Federal construction cost for the six levee projects between Cowden and Vandalia as determined from enhancement of property values and increased yields. Levees below Carlyle were authorized without the provision of local contribution for enhancement. Local interests would be required to contribute toward the cost of the reservoirs for the water-supply benefits provided, an amount equal to 7.85 percent of the cost of the Carlyle Reservoir and an amount equal to 7.06 percent of the cost of the Shelby- ville Reservoir, plus an appropriate share of the annual maintenance and operation costs for the Carlyle and Shelbyville Reser- voirs; for the recreation and fish and wildlife benefits provided, an amount equal to 5.75 percent of the cost of the Carlyle Reser- voir, to be paid at the time the Shelbyville Reservoir is built, and an amount equal to 9.65 percent of the cost of the Shelbyville Reservoir, and for the benefits due to increased net returns to lands, an amount equal to 6.86 percent of the cost of the Shelby- ville Reservoir. With respect to the dam at Carlyle which is now under construction, the State of Illinois, under authority of its Senate bill 137, 70th general assembly, and represented by the department of public works and buildings, has executed a contract with the United States providing for payment of: (1) 7.85 percent of all allocations made by the Government for construction of this portion of the project, and (2) a sum equal to 8.62 percent of actual Federal costs for operation and maintenance. The percentages 662 REPORT OF THE CHIEF OF ENGINEERS, U. S. ARMY, 1959 set forth were determined by the separable cost-remaining benefits method. The aforesaid contract, signed by the district engineer as contracting officer, has been approved by the Secretary of the Army. The State of Illinois is currently making payments thereunder. Operations and results during fiscal year. Costs incurred were $253,933 for engineering and design, $55,344 for other distributive costs, $79,623 for land acquisition, $780 for leasing program, and $1,100 for relocations. Work by contract consisted of $200,000 for dam construction, and $355,841 for acquisition of lands including $105,681 of contributed funds. Total costs for the fiscal year were $946,621. Total costs to June 30, 1959, were $1,895,135, including $105,681 of contributed costs. Condition at end of fiscal year. Construction was initiated on the dam at Carlyle. Real estate memorandum for the reservoir and design memoranda for availability of construction materials and for relocation of pipelines, power and telephone lines, were submitted during the fiscal year. Construction on the first stage of the main dam, Carlyle (comprising about 2,000 linear feet of embankment and appurtenant work) was initiated in November 1958, and is scheduled for completion in December 1959. Con- struction of access roads and an administration and shop building at the right abutment of the main dam and relocation of electric and telephone lines and an oil pipeline in the vicinity of the main dam are scheduled for initiation in the latter part of fiscal year 1960. To date 2,221 acres have been acquired, which include all lands needed for construction of the dam.
