basin No. 3, mile 4.7. Local interests donated the necessary land for the widening. Terminal facilities.-All terminal facilities on the lake front and in the entrance channel up to the Elgin, Joliet & Eastern Railway bridge are owned and operated by two steel companies, except a 450 linear-foot reservation owned by the Engineer Department. These facilities consist in part of two slips which are 2,900 and 1,300 feet long, respectively, and also of about 2,961 feet of wharfage facing on the entrance channel. These terminals are fully equipped and are considered adequate for existing commerce. Additional dockage exists on the lake front and along the entrance channel, but for various reasons it is not now suitable for terminal uses. Between the Elgin, Joliet & Eastern Railway bridge and The Forks there are about 50,500 feet of wharfage, including 14 slips and drydocks, of which about 31,300 feet are in use. These wharves are owned and operated by various private and industrial concerns handling ore, coal, grain, lumber, etc. About 3,600 fee: are in use for shipbuilding purposes. The ore, grain, and coal wharves are fully equipped and are considered adequate for existing commerce. There are no public wharves on the Calumet River. Operations and results during fiscal year.-New work.—Preparation of definite project report was carried on at a cost of $315.94. Maintenance.-Miscellaneous surveys were carried on at a cost of $10,749.47. A total of 158,735 cubic yards was removed by contract at a cost of $93,291.14, and 1,010 tons of riprap were placed along a portion of the crib breakwater at a cost of $5,571.82. The total cost was $109,928.37, of which $315.94 was for new work and $109,612.43 was for maintenance. The total expenditures were $21,296.52. Condition at end of fiscal year. The existing project was 61 percent complete. The work remaining to be done to complete the project is the construction of turning basins Nos. 2 and 4, dredg ing portions of the outer harbor, deepening, widening, and straightening the Calumet River, dredging an approach channel to the harbor through the shoals outside the detached breakwater. and closing the gap between the breakwaters. The timber breakwater (6,712 feet, completed in 1904; concrete superstructure completed in 1924) is in good condition, except that some riprap is required. The cellular type steel-sheet pile breakwater (5,007 feet. completed in 1935) is in good condition. Under permit from the Secretary of War, the Youngstown Sheet & Tube Co. and its predecessors have removed all the south pier (completed in 1897) and replaced it with a concrete dock wall 2,961 feet in length and 50 feet southerly of the pier's original location. Under permits from the Department, the Defense Plant Corporation has built two sections of bulkhead on the east side of the river between a point opposite the Semet Solvay slip and the new turning basin No. 3 at mile 4.7. The United States has widened and deepened the channel adjoining the new bulkhead except along the rock section, where the widening was done by the corporation. Depths in the entrance channel vary from 30 to 25 feet. The controlling depth in the river is 19.9 feet up to and including turning basin No. 5 at the head of the project. Depths are based on soundings completed in March 1945, and are referred to low water datum. The mean water level in June 1945 was 2.34 feet above datum. The head of navigation for deep-draft vessels in the river is at turning basin No. 5 at the entrance to Lake Calumet. Dredging in the outer harbor has produced the project depth of 26 feet over an area of 700 acres. Depths in the portions to be dredged vary from 2 to 25 feet. The total cost, all funds, was $8,189,091.17, of which $2,565,458.77 regular funds and $3,036,603.05 Public Works funds, a total of $5,602,061.82 was for new work and $2,587,029.35 for maintenance. Total expenditures were $8,100,115.16, including $3,036,603.05 Public Works funds. Proposed operations.-The balance unexpended at the end of the fiscal year ($173,786.07) plus an allotment of $12,000 made during July 1945, a total of $185,786.07, will be applied as follows: Accounts payable June 30, 1945.

Location.-Northeastern Illinois (Cook County), within the southeasterly limits of the city of Chicago, just west of and connected by a short channel with turning basin No. 5, the landward limit of the project known as Calument Harbor and River. (See U. S. Lake Survey Chart No. 755.) Existing project. This provides for dredging areas A and B in the south end of Lake Calumet, including an entrance channel 300 feet in width from turning basin No. 5 to a depth of 21 feet. The project depth is referred to low water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. Fluctuations in stage of the lake are practically those resulting from changes of water level in Lake Michigan. On Lake Michigan seasonal fluctuations in mean stage from low water in winter to high water in summer average about 1.2 feet. Local and temporary fluctuations of 0.1 to 0.5 foot, due to wind and difference in barometric pressures, occur daily. Seiches of 3 to 4 feet occur at infrequent intervals. The estimate of cost for new work, made in 1933, was $460,500. The estimated annual cost of maintenance is $10,000. The existing project was authorized by the River and Harbor Act of August 30, 1935 (H. Doc. No. 180, 73rd Cong., 2d sess.), which document contains the latest published maps of the Illinois waterway. Local cooperation.-Fully complied with. Terminal facilities.-There are no facilities at the present time. The proposed terminal development will have adequate facilities for operation of a satisfactory lake-river transfer terminal. Operations and results during fiscal year.-Miscellaneous surveys were carried on at a cost of $2,750, all maintenance. The total expenditures were $2,750. Condition at end of fiscal year.-The existing project was completed in 1937 at a saving of $55,489 under the estimated cost. Depths in the channel from Turning Basin No. 5 on the Calumet River to the dredged area in the lake vary from 18 to 21 feet. Depths in the dredged area, about 56.5 acres, at the south end of the lake vary from 15 to 18 feet. Depths are based on soundings completed in December 1944 and are referred to low water datum. The mean water level in June 1945 was 2.34 feet above datum. Except in the dredged area. depths in the lake vary from 1 to about 10 feet, but in general are so shallow that no navigation is possible in the undredged portion except by very light-draft vessels. The total cost of the work was $407,761.57, of which $405,011.57 was for new work and $2,750 for maintenance. The total expenditures were $407,761.57. Proposed operations.—An anticipated allotment of $3,000 will be applied to sounding, sweeping, and removal of obstructions, by hired labor during fiscal year 1946. The additional sum of $180,000 can be profitably expended during the fiscal year 1947 as follows: Maintenance: Sounding, sweeping, and removal of obstructions, by hired labor, $5,000 Dredging area at the south end of the lake and in the entrance Total Cost of new work to June 30, 1945 Cost of maintenance to June 30, 1945 Total cost of permanent work to June 30, 1945.

INDIANA HARBOR, IND. 2.750 2750 2, 750.00 2,750.00 180,000.00 Location.-Northwestern Indiana (Lake County), on southwest shore of Lake Michigan, 18 miles southeast of Chicago Harbor. (See U. S. Lake Survey Chart No. 755.) Previous project.-Adopted by River and Harbor Act of June 25, 1910. For further details see page 1943 of Annual Report for 1915, and page 1520 of Annual Report for 1938. Existing project. This provides for (a) A northerly rubble-mound breakwater, 2,520 feet long, an easterly reinforced concrete-caisson breakwater 1,507 feet long, an extension of this latter breakwater about 2,300 feet to the north and the construction and placing of a lighthouse crib. (b) An entrance channel generally 800 feet wide, with a depth of 28 feet at the outer end and 26 feet at the inner end. (c) Dredging the anchorage and maneuver basin in the outer harbor to a depth of 26 feet, and the channel between the bulkheaded fills in the outer harbor to a depth of 25 feet. (d) Widening the main stem of the Indiana Harbor Canal to a bottom width of 260 feet with a depth of 22 feet from the outer harbor to the forks, and dredging the Calumet River Branch from the forks to One Hundred and Forty-first Street to the same width and depth. |
