Racine Harbor, Wisconsin.-The entrance to this harbor originally varied in depth from absolute closure after storms to about 6 feet. The original project was adopted in 1842 or 1843 and contemplated a channel 12 feet deep. In 1866 the project was modified to providing a channel 15 feet deep. There has been expended on this harbor up to June 30, 1890, $241,762.91, resulting in the construction of a north and south pier 1,460 and 1,070 feet long, respectively, and a dredged channel 16 feet deep. During the fiscal year ending June 30, 1891, $399.71 has been expended. Four thousand and eighty-nine cubic yards of material has been removed from the channel under an agreement calling for the restoration of the channel by the removal of 14,000 cubic yards. The constant shoaling at the entrance to this harbor shows that the piers will have to be extended several hundred feet in order to maintain the intended depth. Some 500 feet of the superstructure of the piers should be rebuilt. July 1, 1890, balance unexpended............. Amount appropriated by act approved September 19, 1890..

(See Appendix L L 17.) 18. Kenosha Harbor, Wisconsin.-The original depth of water at the mouth of Pike Creek varied from absolute closure to 3 feet. The original plan of improvement was adopted in 1852 and was directed to securing a channel 12 feet deep by constructing parallel piers and dredging between them. This plan was modified in 1866 so as to secure 15 feet of water by extending the piers and dredging deeper. There was expended upon this harbor up to June 30, 1890, $228,018.34, resulting in the construction of two piers, north and south, 1,600 and 800 feet in length, respectively, 150 feet apart, with a channel of vary. ing depth. In 1875 and 1876 the channel was dredged to 15 feet, but the subsequent appropriations have not been sufficient to maintain this depth, so that the periodical dredging has only provided an available channel of about 12 feet. During the fiscal year ending June 30, 1891, $2,886.20 has been expended, of which $2,500 was spent in dredging the inner harbor in ac cordance with a clause in the river and harbor act of September 19, 1890; an area of about 3 acres was dredged to a depth of 14 feet, about 21,000 cubic yards of material being removed; 5,400 cubic yards was dredged from the channel and good progress made in the pier extension under contract.

Waukegan Harbor, Illinois.-Previous to improvement there was no navigable channel or natural harbor at this place, the adopted project contemplating the construction of an artificial harbor. A project was adopted in 1852 which provided for the construction of a breakwater parallel to the shore in 20 feet of water. One crib was placed in position but was carried away by a storm, and the work was then abandoned. In 1872 another project was submitted for a breakwater in 24 feet of water. No action was taken on this. The present project was adopted in 1880, and provides for the construction of an exterior basin of sufficient capacity for local trade by inclosing a portion of Lake Michigan with pile piers, the entrance channel between the piers and the inclosed area to be dredged to 12 feet. There has been expended on this harbor up to the close of the fiscal year ending June 30, 1890, $110,916.38, resulting in the construction of 2,285 feet of pile pier and the removal of 80,874 cubic yards of material. During the fiscal year ending June 30, 1891, $13,556.82 has been expended in repairs to pile-driver, purchase of materials and extension of north pier, 192 linear feet of this extension being completed at the close of the fiscal year.

Fox and Wisconsin rivers, Wisconsin.-The works for the improvement of the Fox and Wisconsin rivers were purchased by the United States from the Green Bay and Mississippi Canal Company in 1872. With the exception of one stone lock they were all temporary structures and were in bad condition. There was no low-water navigation on the Upper Fox, and on the Lower Fox navigation was uncertain. The adopted project for the improvement of the Fox River contemplated the replacing of the temporary structures with permanent works, the construction of five additional stone locks on the upper river, and widening and deepening the channels throughout the river and canals to 6 feet depth and 100 feet width. The method adopted for the Wisconsin River was to contract the channel way by stone and brush wing dams, in order to give increased depth by concentration and scour. The estimate for both rivers, made in 1874 and 1876, was $3,745,663. The general project of the improvement of the Fox and Wisconsin rivers was referred to the Board of Engineers, who, after systematic observations of the effect of the dams on the improved section of the Wisconsin River, submitted a report, contained in House Ex. Doc. No. 65, Forty-ninth Congress, second session, recommending that no further work be done on wing dams in the Wisconsin River with a view to improving its navigation. The original project, therefore, as far as it relates to the Wisconsin. River, has been abandoned, and the work confined to the Fox River, under the modified project of a Board of Engineers, submitted September 17, 1884, published in the Annual Report of the Chief of Engineers for 1885, approved by the Secretary of War, December 10, 1885, as further modified by authority of the Chief of Engineers, May 14, 1886. The modified project applies only to the Fox River and its needs, and provides for the renovation of eleven old locks and the deepening and widening of the channel of the Fox River from Montello to Green Bay to 6 feet depth and 100 feet width, and that from Portage to Montello 4 feet of water at low water be maintained, the estimate for which was $602,000. The amount expended on the Fox and Wisconsin rivers from 1867 up to the close of the fiscal year ending June 30, 1890, including outstanding liabilities and $145,000 paid to the Green Bay and Mississippi Canal Company for works of improvement under act of June 10, 1872, was $2,912,752.18. The result of this expenditure was: On the Fox River.-The construction of 14 new locks of stone; 17 dams, 4 of which are temporary; 12 cutoffs; 10 miles of canals dredged and deepened. Over 2,000,000 cubic yards of material were dredged from the Upper Fox, and all temporary structures repaired and maintained in working order. Throughout the season of 1890 navigation was continuous with the exception of 17 days in July and August, when it was suspended through the fourth lock at Appleton in consequence of repairs necessitated by the carrying away of the upper gates by a steamer running into them. Under the modified project there remains to be done 2,800,000 cubic yards of dredging and rock excavation, mainly on the Upper Fox. On the Wisconsin River.-One hundred and eight thousand five hundred and twelve linear feet of wing dams had been constructed over a distance of 50 miles, of which a section 9.2 miles in length below Portage had been completed. The result was an increased depth of navi gation wherever the works had been applied. On account of the shifting nature of the sand bars there was never any regular navigation on the river. During the fiscal year ending June 30, 1891, $39,059.54 has been expended and the following work done: A head wall and feeder at the old first lock at Appleton, a wing dam of brush and stone as a shore protection to the Portage Levee, a new tugboat and 2 dump scows built, channels dredged at Grignon Rapids, mouth of the Fond du Lac River, and between De Pere and Green Bay.

Operating and care of locks and dams on Fox River, Wisconsin.— Under the continuous appropriation for operating and care of canals and other works of navigation, it is proposed to maintain existing navigation by timely repairs to old locks until they are replaced by new, and to continue repairs of works that have already been completed and used, injured by floods or otherwise. The amount expended under the indefinite appropriation provided by section 4 of the river and harbor act of July 5, 1884, up to the end of the fiscal year ending June 30, 1890, was $308,779.71. During the fiscal year ending June 30, 1891, $68,989 has been expended, the detailed statement appended to the report of the local engineer officer showing the items of expenditure.

IMPROVEMENT OF CHICAGO AND CALUMET HARBORS, ILLINOIS, OF CALUMET RIVER, ILLINOIS AND INDIANA, AND OF ILLINOIS RIVER, ILLINOIS; ILLINOIS AND MISSISSIPPI CANAL. Officer in charge, Capt. W. L. Marshall, Corps of Engineers; Division Engineer, Col. O. M. Poe, Corps of Engineers. 1. Chicago Harbor Illinois.-The present project was adopted in 1870 and modified in 1878, and contemplates: a. The formation of an outer harbor or basin, by inclosing a portion of Lake Michigan just south of and adjoining the entrance to Chicago River, for the purpose of increasing the harbor facilities of Chicago. b. The construction of an exterior breakwater in deep water north of the entrance to Chicago River and about 1 mile distant, to shelter the approach to the river and outer harbor entrance, and to form a harbor of refuge at the southern end of Lake Michigan. There has been expended upon this project since 1870 $1,616,435.52, which expenditure has resulted In the completion of the outer harbor, except 267,000 cubic yards of dredging, to attain 16 feet of water.at low water throughout the required basin. In the completion of the exterior breakwater 5,413 feet in length; in keeping the entrance to Chicago Harbor dredged; in maintaining the various piers and breakwaters, and in maintaining in serviceable condition the plant pertaining to the work. During the past fiscal year the work consisted in a. Exterior breakwater.-In placing a heavy decking over about twothirds of the width of the exterior breakwater, composed mainly of material on hand suitable for no other purpose. b. Outer Basin and North Pier, Chicago Harbor.-Under contract rebuilding superstructure over easterly breakwater, outer basin, and north pier, Chicago Harbor, was commenced, and at the close of the fiscal year about 1,700 linear feet of superstructure over easterly break. water, except decking and stone filling, had been completed. This work includes 749,240 feet B. M., pine timber, and 70,573 pounds iron drift bolts, placed in the work. The superstructure over the southerly breakwater, outer basin, and for about 1,225 feet of south pier, entrance to Chicago River, now needs renewal, and there is 267,000 cubic yards of dredging needed to complete the outer basin. The outer basin has never fulfilled the purposes of its construction on account of the litigation that has existed for many years as to the riparian ownership along the lake front, and the dredging in that basin may well be postponed until the lake front is in demand for harbor and dock purposes, when the material will be valuable for filling docks.

Calumet Harbor, Illinois.-This improvement is to furnish a safe and practicable entrance to Calumet River and the port of South Chicago, by parallel piers, 300 feet apart, extending from shore to deep water in the lake, and by dredging between them to 16 feet in depth at low water. The work commenced in 1870, and at the close of the fiscal year 1891 there had been expended $411,457.46, as the result of which 3,640 linear feet of the North Pier and 2,020 linear feet of the South Pier have been completed and 413,434 cubic yards of material dredged, giving a channel 16 feet in depth instead of 7 feet, as originally existed. During the past fiscal year under contract for dredging 29,088 cubic yards of material has been removed from the channel, which had de |
