estimate of annual cost of operation and care of the locks and dams made in 1936 is $100,000. The existing project was authorized by the following river and harbor acts: The latest published maps are contained in H. Doc. No. 146, 67th Cong., 2d sess., and in H. Doc. No. 294, 68th Cong., 1st sess. 672607-46-pt. 1, vol. 2-32 1 Depth shown is on breast wall, which is controlling depth for upper pool. 2 Original structure built prior to assumption of control by the United States on Sept. 18, 1872. " Depth shown is on upper miter sill, which is controlling depth. 7 Unknown. Recommended modifications of project.-Legislation authorizing the abandonment of that part of the improvement of Wolf River above Fremont and the upper Fox River from the mouth of the Wolf to the Wisconsin River has been recommended in House Document No. 146, Sixty-seventh Congress, second session. Terminal facilities.-The wharf and landing facilities are in general adequate for the accommodation of existing commerce. Operations and results during fiscal year.-Maintenance.Operations consisted of stone paving and other miscellaneous repairs and improvements to canal banks at the following localities: Right bank below Kaukauna fifth lock; right and left banks below Kaukauna fourth lock; right bank above Kaukauna first lock; left bank above Cedars dam; left bank above Appleton fourth lock; left bank below Appleton first lock; and left bank above Menasha lock, by hired labor and use of Government plant, at a total cost of $16,362.40 for maintenance. Operating and care.-Operations consisted of making necessary repairs to locks, dams, canal banks, and lock houses, including painting of all steel work below water surface at De Pere lock; repairing lower gates at Kaukauna fifth lock; and rebuilding upper right wing wall at Little Chute Combined locks, at a cost of $13,702.76. The locks and dams were operated in accordance with the existing project and gages were read at a cost of $96,822.46. All work was done by hired labor and use of Government plant. The total cost of operating care was $110,525.22. The total cost of all work was $126,887.62. The total net expenditures were $135,816.01. Condition at end of fiscal year.-The existing project was about 44 percent complete (upper river, 25 percent; lower, 83 percent). Twenty-two original locks and nine original dams have been rebuilt; five additional locks and dams have been built by the United States. (See existing project for year of completion of each.) The structures and the dredging in pools have increased the original depths generally about 2 feet. The controlling depths at mean low water at the close of the fiscal year were as follows: Fox River: De Pere to 2 miles above mouth of Wolf River_ 2 miles above mouth of Wolf River to Eureka lock_. Eureka lock to Montello lock__ Montello lock to Governor Bend lock__ Governor Bend lock to Portage lock_. Wolf River: Mouth to 1 mile below Partridge Crop Lake_. 1 mile below Partridge Crop Lake to New London_. Harbors on Lake Winnebago.... Feet 6.0 4.5 3.0 2.5 2.0 4.0 2.5 5.5 The practicable drafts of vessels are about one-half foot less than the controlling depths which prevail throughout the year except when the rivers are frozen, usually from December 1 to April 1. The head of navigation for boat traffic is New London on the Wolf River and Portage on the upper Fox, except that during high water on the Wisconsin River boats can proceed from Portage to the Mississippi River. The work remaining to be done to complete the project is dredging in the upper Fox River and the upper portion of the Wolf River; also rock removal and deepening Neenah Channel on lower Fox River. Deepening Neenah Channel is no longer desired by navigation interests. The remaining rock removal is not needed unless there is a material increase in commerce. Additional dredging on the upper river is no longer considered necessary and is not justifiable from an economic standpoint. The costs under the existing project were $871,724.01 for new work and $3,741,215.72 for maintenance including $1,258,124.11 for operating and care, a total of $4,612,939.73. The total expenditures were $4,618,405.75. In addition, the sum of $3,795,495.53 (including $89,309.40 under previous projects) was expended between July 5, 1884, and June 30, 1935, on the operating and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes. Proposed operations.—The balance unexpended at the end of the fiscal year, including accounts receivable ($136,833.48), plus an ! additional amount anticipated to be allotted will be applied as follows: Operation of locks and dams and other works $151, 400.00 Ordinary maintenance and repairs Improvements and reconstruction 28, 856. 37 13, 000. 00 Total operating and care Grand total 193, 256. 37 218, 333. 48 Dredging is required for maintenance of project dimensions of channels. Repairs to canal banks are required. The completed locks and dams must be operated and maintained. The additional sum of $215,000 can be profitably expended during the fiscal year ending June 30, 1947, as follows: Maintenance: Operation of U. S. bucket dredge Winneconne, July $10,000 General repairs to canal banks by hired labor and 15,000 |
