Port Washington Harbor, Wisconsin.-The present project for the improvement of this harbor, adopted in 1869 and modified in 1870 and 1876, was for the formation by dredging of two interior basins, baving a combined area of about 53 acres, with a depth of 12 feet, and a channel of the same depth connecting them with the lake, the channel entrance to the basins to be north of the mouth of the Sauk River, inclosed between two piers. The natural channel at the mouth of the Sauk River was narrow, and at the shoalest point had a depth of but 1 foot. At the close of the fiscal year ending June 30, 1889, dredging was being done at this harbor, and on the above-mentioned date 3,510 cubic yards of material had been removed. The amount expended to June 30, 1889, is $169,161.54, and has resulted in the construction of a north and south pier 920 and 1,226 feet long, respectively, with 400 feet revetment along the north bank of the river, extending to the inner end of the south pier; in the formation of two interior dredged basins of 23 and 3 acres, respectively, with an average depth of about 9 feet in the north and 8 feet in the west basin, and in making a navigable channel between the piers of 11 feet. It is proposed to extend the appropriation asked for in completing the south pier and maintenance of works. July 1, 1888, amount available.... Amount appropriated by act of August 11, 1888.

Harbor of refuge at Milwaukee Bay, Wisconsin.-In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888. The project for the work was approved in 1881, and contemplated the formation of an artificial harbor by inclosing a portion of Lake Michigan within an outer breakwater of crib-work upon a stone foundation. This harbor will furnish 417 acres of safe mooring ground beyond the 18-foot contour and about twice this area beyond the 12-foot contour. Work began in 1881, and up to June 30, 1889, there has been expended $360,812.22, resulting in the completion of 3,550 linear feet of the substructure of the breakwater, over which 3,100 linear feet of superstructure has been built. During the fiscal year ending June 30, 1889, 250 feet of substructure has been built. The breakwater when completed will be 7,250 feet in length. There remains, then, to be constructed 3,700 linear feet of substructure and 4,150 linear feet of superstructure to complete the work. The funds asked for are to be applied to the extension of the breakwater. The harbor is now used to a limited extent as a shelter from northeast storms. Its value will rapidly increase as the east arm is extended.

Marshall, Corps of Engineers, until September 19, 1888. The present project was adopted in 1852, and was directed to securing 12 feet of water at the entrance to the river and to protecting this channel by parallel piers. Since that date a channel, 18 feet in depth and of sufficient width, has been formed by extending the piers and dredging. The project has been completed, and consequently the only expenditures now demanded are for the maintenance of the piers by timely repairs and the depth of the channel by dredging. The original depth of water at the mouth of the river was not more than 34 feet. The United States has expended on this harbor up to June 30, 1889, $294,103.87, in addition to $321,355.66 by the city of Milwaukee. During the fiscal year ending June 30, 1889, 340 linear feet of superstructure over the outer section of the south pier has been cut down and rebuilt. The stone superstructure of the north pier and the concrete paving need repairing. Repairs are also needed at the inshore ends of both piers. No dredging has been done at this harbor since 1880, and the channel has narrowed and shoaled somewhat. It will require the removal of some 30,000 cubic yards of material to restore the channel to its projected dimensions. It is intended to apply the appropriation asked for to the abovementioned repairs and dredging.

The entrance to this harbor originally varied in depth from absolute closure after storms to about 6 feet. The original project was adopted in 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, 1889, $238,706.55, resulting in a north and south pier, 1,460 and 1,070 feet in length, respectively, and a channel 16 feet in depth. During the past fiscal year the channel, which had shoaled to barely 12 feet, was dredged out to 16 feet, thus restoring it to the projected dimensions, 36,356 cubic yards of material being removed by contract. 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 of 16 feet. Some 500 feet of the superstructure of the piers needs rebuilding. It is proposed to expend the appropriation asked for in the above mentioned repairs and pier extension.

Marshall, Corps of Engineers, until September 19, 1888. The plan of improvement by parallel piers and dredging was adopted in 1852, and was first directed to securing a channel 12 feet deep. This was modified in 1866 so as to secure a channel 15 feet deep. The original depth was 4 feet or less; sometimes the mouth of Pike Creek was entirely closed. In 1875 and 1876 this harbor was dredged to 15 feet, but the appropriations have been insufficient 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, 1889, nearly 25,000 cubic yards of material has been dredged from the channel between the piers, by contract, thus restoring the channel to a uniform depth of 15 feet. The contract was completed November 30, 1888, and soundings made in May, 1889, showed that a bar had reformed across the front of the harbor with a least depth of 9.8 feet. Arrangements have been made for removing this bar. The only method of preventing this reforming of the bar is to extend the piers, and it is proposed to expend the appropriation asked for in this pier extension and in repairs to superstructure. There has been expended on this harbor up to June 30, 1889, $226,596.71, resulting in the construction of two piers, north and south, being respectively 1,600 and 800 feet in length, and a channel of varying depth.

Waukegan Harbor, Illinois. In charge of Capt. W. L. Marshall, Corps of Engineers, until September 19, 1888.-The present project was adopted in 1880, and, as since modified, consists in excavating a small basin in the low ground between the lake and the bluffs to form the harbor, and in dredging an entrance between piers from the lake to the basin. During the fiscal year ending June 30, 1889, by hired labor the south pier was extended 248 feet. A contract was entered into for dredging the entrance channel and interior basin and on the above-mentioned date 17,805 cubic yards of material had been removed. There has been expended on this harbor up to the close of the fiscal year $100,765.37, resulting in the construction of a total length of pile pier-work of 2,284.5 feet and the removal of the 17,805 cubic yards of material. The prolongation of the fore-shore on the north side of the harbor will necessitate a material extension of the entrance piers, and it is proposed to expend the appropriation asked for in pier extension and the further prosecution of the approved project.

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. These works were all, except one stone lock, temporary structures, all of them in bad condition. There was no low-water navigation on the Upper Fox, and on the Lower Fox navigation was uncertain. For the Fox River.-The adopted project contemplated the replacing of the temporary structures with permanent works, the construction of five additional stone locks on the Upper Fox, and widening and deepening the channels throughout the river and canals to 6 feet depth and 100 feet width. For the Wisconsin River.-The method adopted has been to contract the channel-way by wing dams of brush and stone, to give increased depth by concentrating the water and by scour due to the increased currents. The estimate, including the Wisconsin River, made in 1874 and 1876, was $3,745,663, since which time there has been appropriated $1,780,000, leaving for completion of the adopted project $1,965,663. The general subject of the improvement of the Fox and Wisconsin rivers was referred to The Board of Engineers, which, 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, 1884, 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 contemplates the renovation of eleven old locks and the deepening and widening the channel of the Fox River from Montello to Green Bay to 6 feet depth and 100 feet width, the estimate for which is $602,000. The amount expended on the improvement of the Fox and Wisconsin rivers, from 1867 to date, 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, is $2,754,873.13. The result of this expenditure has been: On the Fox River.-The construction of 14 new locks of stone; 13 dams, 4 of which are temporary; 12 cut-offs; 10 miles of canals dredged and deepened. Over 2,000,000 cubic yards of material has been dredged from the Upper Fox, and all temporary structures repaired and maintained in working order. The navigation has thus been continuous throughout the season from Portage to Green Bay, there being at an ordinary stage of water 24 feet navigation on the Upper Fox, and 54 feet on the Lower Fox, except at the entrance of Lake Winnebago, where there is only 4 feet. During the season from July to November, 1888, navigation was partially suspended from Lake Winnebago to Appleton, due to the mills drawing more water than the discharge of the Fox River, thus lowering the levels of the Lake Winnebago and Little Butte des Morts pools. Under the modified project there remains to be done 2,800,000 cubic yards of dredging and rock excavation, mainly upon the Upper Fox, and one dam at Appleton, with sluice-ways, the old works to be manitained under the continuous appropriation. During the fiscal year ending June 30, 1889, the following work has been done: On the Upper Fox.-The work was confined to the maintenance of the channel by dredging, and to timely repairs to locks, dams, and embankments. On the Lower Fox.-Dredging was continued in the Menasha Channel, to connect the deep rock cut with deep water in the lake. The various works on the Lower Fox were maintained in serviceable condition. Extensive repairs were made to dredging plant, and to Rapid Croche and Menasha locks. Good progress was made in the construction of the Appleton lower dam, and general repairs made to locks, dams, and canal banks. |
