Improvement of Fremont Channel and McLeod H. Doc. No. 581, 62d Cong., 2d sess. Lake, at Stockton. A 26-foot channel up to Stockton. June 25, 1910 July 25, 1912 Jan. 21, 1927 Aug. 30, 1935 * Aug. 26, 1937 The widened 30-foot channel up to Stockton The original 30-foot channel up to Stockton. H. Doc. No. 554, 68th Cong., 2d sess.1 Rivers and Harbors Committee Doc. 1 Contains latest published maps. 2 Included in the Public Works Administration program Sept. 6, 1933. Local cooperation.-Local interests are required to furnish, free of cost to the United States, suitable areas for the disposal of dredged material during initial construction and future maintenance, and necessary rights-of-way, and shall assume the maintenance of levees. All requirements for work done to date have been fulfilled. Terminal facilities.-There are a number of privately owned river freight warehouses along the river and in the delta region. Freight is handled on the bank, except at and below Antioch, where extensive wharves and warehouses exist. The city of Stockton port terminal has 3,400 linear feet of public wharves served by 32 miles of public belt railroad. All except two oil terminal piers and a 508-foot wharf have transit sheds. In addition to privately operated grain and lumber terminals, a cotton compress and warehouse, a bean-cleaning plant, oil refinery, and storage tanks, a large storage tank for crude molasses, and bank of silos for cement storage, there are numerous publicly and privately owned shallow-draft wharves at Stockton. Certain facilities at the Stockton port terminal are in use for military purposes. A naval supply depot (Stockton Annex), about 50 percent complete, is under construction on Rough and Ready Island, bounded by the Stockton Deep Water Channel on the north side, San Joaquin River on the east side, and Burns Cut-off on the south and west sides. In New York Slough there are 13 wharves, including 1 for deep-sea vessels. One wharf has a spur track and 2 have oil pipe lines. The facilities are considered adequate for existing commerce. Operations and results during fiscal year-New work.-None. Maintenance.-The 30-foot channel to Stockton was partially restored to project dimensions at the confluence of the main river and Stockton Channel and vicinity by the excavation of 188,000 cubic yards by the pipe line dredge Alamitos under rental contract, at a cost of $12,865.48, including surveys and inspections. Total cost for the fiscal year was $12,865.48, for maintenance; total expenditures were $7,533.47. Condition at end of fiscal year.-The existing project was 95 percent complete, the work remaining to be done being the dredging of a 9-foot channel in Mormon Channel to Center Street, Stockton; completion of restoration of levee on north side of Venice Island Cut; and setting back of levees and bringing levees to grade and section where needed. The controlling depth from mouth of the river in Suisun Bay to Mormon Channel, 41 miles, is 29 feet (30-foot depth is being restored); thence to Edison Street, three-quarters of a mile, 22 feet; and thence to head at El Dorado Street, one-half mile, 10 feet. A 3-foot depth is available in Mormon Channel and 7 feet in Fremont Channel and McLeod Lake. The river, from its junction with Stockton Channel to Hills Ferry, usually has a controlling depth of 4 feet from April to June, inclusive. Navigation in this section above the San Joaquin bridge (Southern Pacific R. R. crossing) is impracticable in the low stages after June. All depths are referred to mean lower low water. The total expenditures were $5,524,531.90, including $1,158,347.99 from Public Works funds, of which $207,197.64 was for the 30-foot channel in Suisun Bay. In addition, $1,307,500 was expended from contributed funds for new work and $1,250 for maintenance. Proposed operations. The balance unexpended June 30, 1945, amounting to $143,170.39, and an additional allotment to be made will be applied as follows: Accounts payable Maintenance: Dredging 9-foot channel in Stockton Channel, above Edison Dredging 30-foot channel in Stockton Channel and in San Snagging in main river, above and below Stockton Channel, $6, 157. 73 27,000.00 102, 000.00 15, 100.00 3,000.00 Surveys and miscellaneous inspection and maintenance, July to December 1945 Total for maintenance Total application of funds $5, 012. 66 152, 112. 66 158, 270. 39 The additional sum of $261,000 can be profitably expended during the fiscal year 1947, as follows: New work: Dredging Mormon Channel from its mouth to Center Street, Stockton, to a depth of 9 feet, by pipe-line dredge and other excavating plant, by contract, April to June 1947 Maintenance: Dredging 9-foot channel in Stockton Channel, above Edison Total for maintenance Grand total $150,000 $5,000 84, 000 12,000 5, 000 5, 000 111, 000 261, 000 Cost and financial summary Cost of maintenance to June 30, 1945 Cost of new work to June 30, 1945 Total cost of permanent work to June 30, 1945 Minus accounts payable June 30, 1945 Net total expenditures Unexpended balance June 30, 1945 Total amount appropriated to June 30, 1945 Outstanding liabilities June 30, 1945 $6, 847. 73 40, 260.00 $47, 107.73 Balance available June 30, 1945 Amount (estimated) required to be appropriated for completion of existing project 96, 062.66 150,000.00 Amount that can be profitably expended in fiscal year ending June 30, 1947: In addition $1,307,500 for new work and $1,250 for maintenance were expended from contributed funds. 2 Exclusive of available funds. 2. STOCKTON AND MORMON CHANNELS (DIVERTING CANAL), CALIF. Location. This is an artificial cut located about 2 miles northeast of Stockton. (See U. S. Geological Survey sheet, Stockton quadrangle.) Existing project. This provides for diverting the waters of Mormon slough before reaching Mormon and Stockton Channels by means of a dam in the slough 3 miles east of Stockton, and a canal 150 feet wide, with average cut of 7.9 feet, thence to the north branch of the Calaveras River, 4.63 miles; by the enlarg ment of the cross section of this branch to 1,550 square feet, thence to its mouth at the San Joaquin River, 5 miles; and by the construction of a levee along the west side of the canal and the south side of the north branch of the Calaveras River from the material excavated. The height of the levee is limited by necessary railway and highway crossings to about 3 feet above the contemplated flood surface. The canal is empty during the greater part of the year, but at times of extreme flood there is a depth of about 12 feet, and at ordinary flood a depth of about 10 feet. The estimate of cost for new work, revised in 1906, was $280,395. The latest (1918) approved estimate for annual cost of maintenance is $5,000. The existing project was authorized by the River and Harbor Act of June 13, 1902 (H. Doc. No. 152, 55th Cong., 3d sess., and Annual Report for 1899, p. 3188). The latest published map is in House Document No. 256, Sixty-third Congress, first session. Local cooperation.-Fully complied with. Terminal facilities.-See report on San Joaquin River, Calif. Operations and results during fiscal year.-Clearing brush from the channel was done at a cost and expenditure of $3,016.30, including inspections, for maintenance. Condition at end of fiscal year. The existing project was completed in 1910. Most of the silt formerly deposited in Stockton and Mormon Channels is diverted therefrom by this canal, obviating serious inconveniences to navigation and the expensive annual dredging. 3 The total cost was $362,530.41, of which $253,151.03 was for new work and $109,379.38 for maintenance. Total expenditures were $362,530.41. Proposed operations.-The balance unexpended June 30, 1945, amounting to $8,660.47, will be applied to maintenance, including removal of brush, overhanging trees, and other obstructions from the channels and banks of both sections of the diverting canal, by contract, from July to December 1945, along with miscellaneous inspections. The additional sum of $5,000 can be profitably expended during the fiscal year 1947 for maintenance, as follows: Removal of brush, overhanging trees, and other obstructions from the channel and banks of both sections of the diverting canal, by hired labor and Government plant, July to September 1946 Dredging deposits of silt from the Calaveras section of the diverting canal, by contract, December 1946 Miscellaneous inspections, during entire fiscal year Total for maintenance $2,500 2,000 500 5,000 Amount that can be profitably expended in fiscal year ending June 30, 1947, for maintenance1 1 Exclusive of available funds. 5,000.00 3. MOKELUMNE RIVER, CALIF. Location. This river rises near the crest of the Sierra Nevada and empties into the San Joaquin River 20 miles above the mouth of the latter. (See U. S. Geological Survey topographic map of the Sacramento Valley, Calif.) |
