CHICAGO RIVER, ILL. Location. Cook and Lake Counties, Ill., the navigable portions being wholly in Cook County and the city of Chicago. (See U. S. Lake Survey Chart No. 752.) For description see page 1467 of Annual Report for 1932. Previous projects.-Adopted by the River and Harbor Act of June 3, 1896, modified by acts of March 3, 1899, and June 13, 1902. For further details see page 1942 of Annual Report for 1915, and page 1513 of Annual Report for 1938. Existing project. This provides for maintenance dredging to 21 feet below the hydraulic grade line, corresponding to low-water datum in Lake Michigan, of the main river from Rush Street to the junction of the North and South Branches (0.7 mile), the North Branch from the junction to North Avenue (2.22 miles), the North Branch Canal (1.04 miles), and the North Branch Turning Basin, the channels and turning basin to be maintained to project depth to within 20 feet of existing docks. The width of channel in main river varies from 200 to 300 feet, in North Branch from 50 to 150 feet, and in the North Branch Canal from 70 to 110 feet. All depths are referred to low-water datum for Lake Michigan which is 578.5 feet above mean tide at New York, with due allowance for hydraulic grade resulting from the drainage canal. The estimate of cost for new work, made in 1899, was $810,600.) exclusive of amount expended on previous project. The latest (1928) approved estimate of annual cost of maintenance is $20,000. The existing project was authorized by the following river and harbor acts: Acts Work authorized Documents The latest published map is in the Annual Report for 1914, opposite page 2928. Recommended modification of project.-On April 17, 1944, the Chief of Engineers recommended that the project for the Chicago River be modified to provide for a channel 9 feet deep between North Avenue and Addison Street; the channel between North and Belmont Avenues to extend to within 30 feet of existing bulkheads and river banks; and then to Addison Street with a bottom width of 50 feet, at an estimated cost to the United States of $28,000 for construction and $15,000 annually for maintenance in addition to the amount now required, subject to the condition that local interests furnish assurances satisfactory to the Secretary of War that they will hold and save the United States free from damages which may result from construction and maintenance of the improvement (H. Doc. No. 767, 78th Cong.; 2d sess.). Local cooperation. Fully complied with. Terminal facilities. In the Chicago River and its branches there is a total wharfage, including numerous slips, of about 150,000 feet, about 15,000 feet of which is used by private interests for shipping purposes. These terminals are owned and operate! by steamship lines, grain, coal, and lumber companies, and various other industries. They are more than adequate in extent for existing commerce. Except for the State of Illinois barge termina and elevator at Damen Avenue on the South Branch (mentioned in terminal facilities on the Illinois River), and the frontage along Wacker Drive, owned by the city, there are no publicly owned docks, wharves or other terminal facilities on the main river or its branches. Operations and results during fiscal year.-Miscellaneous surveys were carried on at a cost of $3,146.61, of which $419.91 was a minus adjustment from the previous year. Net cost was $2,726.70. Adjustment in yardage dredged resulted in a reduction 5,733 cubic yards at a reduced cost of $2,884.54. Total expendires were $77,176.46. Condition at end of fiscal year.-The existing project was comleted in 1914. The controlling depths are as follows: In the ain river, 21 feet; in the North Branch of the river up to the orth Branch Turning Basin, 21 feet; in the North Branch Canal, 1 feet. Depths in the turning basin are generally 21 feet to withà 40 feet of the docks, decreasing to about 10 feet at the docks. epths are based upon soundings taken in July and August 1944, nd are referred to low-water datum. The mean water level in une 1945 was 2.34 feet above datum. The heads of navigation or deep-draft vessels are Belmont Avenue on the North Branch nd Leavitt Street on the West Fork of the South Branch, 5.97 nd 5.52 miles, respectively, from the Michigan Avenue Bridge. The total cost was $1,545,262.45, of which $544,678.70 was for ew work and $1,000,583.75 was for maintenance. The total exenditures were $1,545,262.45. Proposed operations.-The balance unexpended at the end of he fiscal year ($4,939.15) plus an additional amount anticipated o be allotted will be applied to maintenance, sounding, sweeping, nd removal of obstructions by hired labor, fiscal year 1946, 7,209.15. The additional sum of $5,000 can be profitably expended during The fiscal year 1947 for sounding, sweeping, and removal of obtructions by hired labor.

Location.-Northeastern Illinois (Cook County), near the southern end of Lake Michigan, 1211⁄2 miles south of Chicago Harbor, and known on the Great Lakes as South Chicago Harbor, it being in the southerly part of and within the corporate limits of the city of Chicago, except for a part of the breakwaters and of the anchorage behind same, which are in Indiana. The Calumet River is within the Chicago city limits. (See U. S. Lake Survey Chart No. 755.) For description, see page 1471 of Annual Report for | 1932. Previous projects.-The original project for Calumet Harbor was adopted by River and Harbor Act of July 11, 1870, and modi-! fied August 11, 1888. Work was continued under these projects until 1896. The original project for Calumet River was adopted by River and Harbor Act of July 5, 1884, and modified August 5, 1886. For further details, see page 1943 of Annual Report for 1915 and page 1515 of Annual Report for 1938. Existing project. This provides for the following work: (a) For an outer harbor protected by a breakwater extending! eastward from the shore about 4,400 feet and thence southeasterly about 8,100 feet to the harbor entrance. (b) For an approach channel 3,200 feet wide and 28 feet deepthrough the shoals outside the breakwater. (c) For an outer harbor channel and anchorage area 3,000 feet wide and 26 feet deep. (d) For an entrance channel to the river 350 feet wide and 26 feet deep to the Elgin, Joliet & Eastern Railway bridge. (e) For a channel in Calumet River of 200-foot minimum width. 25 feet deep to the Semet-Solvay wharf near One Hundred and Eleventh Street, thence 23 feet deep through the rock section to near One Hundred and Fourteenth Street, thence 21 feet deep to One Hundred and Twenty-second Street, and thence 21.5 feet deep to and including turning basin No. 5. (f) For widening and straightening the river channel, except through the rock cut, to within 20 feet of bulkhead lines now or hereafter established. (g) For five turning basins spaced along the river channel, of suitable size for turning the largest lake cargo vessels and each of the same depth as the adjacent channel. The project depths are referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. Fluctuations in stage of the river 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, revised in 1945, is $9.110.000. exclusive of amounts expended on previous projects. The latest 1945) approved estimate of annual cost of maintenance is 140,000. The existing project was adopted by the following river and arbor acts: ane 25, 1910 ept. 22, 1922 Provided for shape and dimensions of turning Consolidated the 2 projects for Calumet Harbor ug. 30, 1935 Detached breakwater; dredging the outer harbor far. 2, 1945 Documents Annual Report, 1896, pp. 2584 et seq., and H.

(Contains latest published map of the harbor.) 1Included in Public Works Administration program Sept. 6, 1933, and Dec. 16, 1933. Local cooperation. The act of March 3, 1905, required as a condition precedent to Federal expenditures upon any one of the five turning basins the donation to the United States of the land necessary for that turning basin and have either provided any necessary bulkheads or have released the United States from all damage to adjacent lands by reason of the excavation. As a result the land needed for turning basins Nos. 1, 3, and 5 has been conveyed to the United States. The total area thus conveyed is 17.85 acres, and the value of the land at the time of its conveyance was approximately $35,700. The act of August 30, 1935, provided that the widening of the channel at any locality or the future excavation of a turning basin shall not be commenced until local interests have furnished, free of cost to the United States, the lands or easements necessary for such widening or excavation and have either provided any necessary bulkheads, or have released the United States from all damages to adjacent lands by reason of the excavation. The Republic Steel Corporation has dredged a new turning basin on the east side of the Calumet River just north of One Hundred Twenty-second Street, to replace the original turning basin No. 3, and has constructed a bulkhead along the channel side of the original basin No. 3, and reclaimed the area to provide land for plant expansion. The corporation has also built a bulkhead along two portions of the east side of the river between a point opposite the Semet Solvay slip and the new turning basin No. 3, and has widened and deepened the east side of the rock section between the United States east channel line and its bulkhead. The United States had widened and deepened two portions of the east side of the river between the south end of the rock section and turning |
