8. Harbor of refuge at entrance of Sturgeor, Bay Canal, Wisconsin.— Before the construction of this harbor was undertaken, the Lake Michigan entrance to the Sturgeon Bay and Lake Michigan Ship Canal was entirely unprotected from storms ranging from northeast to southwest. The project of constructing a harbor of refuge at this point was adopted in 1873, and modified in 1879 and 1880. The modified project, as carried out, consists of two piers, each 1,344 feet long, 850 feet apart at the shore line, protecting the lake entrance of the canal, and converging so as to make the harbor entrance 335 feet wide, inclosing an area of about 10 acres, with a depth of at least 16 feet. The total expenditure at this harbor up to June 30, 1890, was $164,903.34, resulting in the entire completion of the piers as projected, and in the dredging of 139,822 cubic yards of material, giving a channel nearly 16 feet deep at the entrance and 14 feet or more thence to the canal, making a depth of 14 feet over the greater part of the sheltered area. During the fiscal year ending June 30, 1891, $66.31 has been expended in care and maintenance of harbor. July 1, 1890, balance unexpended .....

(See Appendix L L 8.) 9. Ahnapee Harbor, Wisconsin.-Previous to the improvement of this harbor the depth of water at the mouth of the Ahnapee River was only about 2 feet. The project of improvement adopted in 1875 and modified in 1884, provided for the formation of a small artifici..I harbor, connected with the lake by a channel 100 feet wide and 12 feet deep, formed by the construction of two piers extending to the 18-foot contour, with a 200foot entrance between the pier-heads. The total amount expended up to June 30, 1890, was $158,772.20, resulting in the construction of two piers, the north one 1,102 feet long, and the south one 1,125 feet, and in the removal of 29,876 cubic yards of rock, and 107,638 cubic yards of sand. During the fiscal year ending June 30, 1891, $2,436.46 has been expended in building 200 feet of superstructure of the north pier. In November, 1890, there was a channel 60 feet wide and 114 feet deep. July 1, 1890, balance unexpended.......... Amount appropriated by act approved September 19, 1890.

(See Appendix L L 9.) 10. Kewaunee Harbor, Wisconsin.-The natural entrance to this harbor was through the Kewaunee River. The river mouth was not more than 20 feet wide, with a depth of about 2 feet at its shoalest point, and was obstructed by submerged bowlders. The project of improvement was adopted in 1881. Its design was to cut a channel 14 feet deep through a neck of land between the river and the lake at a point about 2,000 feet south of the river mouth, and to continue this channel to deep water in the lake by the construction of two parallel piers 200 feet apart, extending from each side of the cut lakeward to the 18-foot contour. The total amount expended on this harbor up to the close of the fiscal year ending June 30, 1890, was $54,777.37, in addition to which the local harbor commissioners had expended $8,042.72. At that time 1,000 feet of the north pier and 1,075 feet of the south pier had been constructed, and a channel 60 feet wide and 12 feet deep had been dredged, 133,291 cubic yards of material having been removed by the Government dredges. During the fiscal year ending June 30, 1891, $9,107.77 has been expended in dredging 77,790 cubic yards of material from the channel. Extension of the pier under contract dated December 13, 1890, is in progress.

Two Rivers Harbor, Wisconsin.-Previous to the improvement of this harbor the natural channel was obstructed by a bar covered by but 2 or 3 feet of water. The project of improvement adopted in 1870 provided for the forma tion of a channel of navigable width and not less than 12 feet deep, to be accomplished by the construction of two piers extending from the mouth of Two Rivers lakeward to the 18-foot contour in Lake Michigan and dredging a channel between them. The amount expended up to the close of the fiscal year ending June 30, 1890, was $199,948.59, resulting in the construction of two parallel piers, as follows: A north pier 1,810 feet long, the inner 1,060 feet of which consists of pile pier, and the outer 750 feet of crib pier; a south pier 1,710 feet long, 960 feet of which is pile pier, and the outer 750 feet crib pier; the crib sections of the two piers begin at points opposite each other and are 230 feet apart; the pile sections are 270 feet apart; 253,372 cubic yards of material has been removed by dredging. During the fiscal year ending June 30, 1891, $2,690.43 has been ex pended in bulkhead protection to the ends of the piers and in the removal of 22,495 cubic yards of material from the channel.

Manitowoc Harbor, Wisconsin.-Previous to the improvement of this harbor but 3 feet of water existed at the shoalest point over the bar at the mouth of the Manitowoc River. The original project adopted in 1852 provided for the construction of two parallel piers, 220 feet apart, extending from the mouth of the river to the 12-foot contour in Lake Michigan. In 1881 this was modified so as to secure a deeper channel by extending the piers to a depth of 181 feet and dredging to not less than 14 feet. The total amount expended up to June 30, 1890, was $299,112.39, resulting in the construction of two piers, the north one 1,970 and the south one 1,900 feet long, 228 feet apart at the shore line and 250 feet at the outer ends, and in the removal of 184,997 cubic yards of material by dredging. During the fiscal year ending June 30, 1891, $3,694.02 has been expended in rebuilding 400 feet of superstructure of the north pier and in dredging 9,464 cubic yards of material from the channel.

(See Appendix L L 12.) 13. Sheboygan Harbor, Wisconsin.-Previous to the improvement of this harbor the natural channel had a depth not exceeding 4 feet on the bar at the entrance of the river. The original project for the improvement of this harbor was adopted in 1852 and had for its object the formation of a 12-foot channel entrance to the mouth of the Sheboygan River. This was modified in 1873 so as to secure a deeper channel by further pier extension and dredging. Both projects were completed within their estimated cost and a channel This amount includes $8,000 required for preservation of piers and for maintenance of channel. was formed 100 feet wide with a depth of 15 to 16 feet between the piers. This was further modified in 1881, the present project having for its object to deepen the channel still further by extending the piers to the 20-foot contour in the lake and dredging to a depth of 18 feet between their outer ends, the depth decreasing to 14 feet at the shore line. The total expenditures up to June 30, 1890, amounted to $302,157.82, resulting in the construction of a north and a south pier, 2,044 and 2,260 feet long, respectively, and the removal by dredging of 207,193 cubic yards of material. There was then a navigable channel 14 feet deep. During the fiscal year ending June 30, 1891, $3,705.46 has been expended in dredging 25,325 cubic yards of material and in riprapping and refilling the south pier.

Port Washington Harbor, Wisconsin.-The natural channel at the mouth of the Sauk River was narrow and at the shoalest point had a depth of but 1 foot. The original project for the improvement of this harbor was adopted in 1869 and provided for two parallel piers extending to 10 feet of water in Lake Michigan and the excavation of an interior basin. This plan was modified in 1870 and again in 1876, and now provides for the excavation of two interior basins with a combined area of 5 acres, with a depth of 12 feet, and a channel of the same depth connecting the basins with the lake. The total expenditure up to June 30, 1890, was $172,468.95, and resulted in the construction of a north and south pier, respectively, 920 and 1,226 feet long, with 400 feet of 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 22 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; 282,219 cubic yards of material was removed by dredging. During the fiscal year ending June 30, 1891, $2,004.25 has been expended in dredging 9,485 cubic yards of material from channel entrance and basins; the north basin has the required depth of 12 feet over nearly its entire area; the south basin, a depth of 8 feet, with a narrow channel of 12 feet on its north side, and the channel entrance, a depth of 12 feet for a width of 80 feet.

Harbor of refuge at Milwaukee Bay, Wisconsin.-The project for the work was approved in 1881 and contemplated the formation of an artificial harbor by inclosing a portion of Lake Michigan, forming Milwaukee Bay within an outer breakwater of cribwork 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 12foot contour. The actual length of the breakwater when completed will be 7,250 feet. Work began in 1881, and up to June 30, 1890, there had been expended $394,901.72, resulting in the completion of 3,650 feet of substructure and 3,100 feet of superstructure, leaving 3,600 feet of the former and 4,150 feet of the latter to complete the work. During the fiscal year ending June 30, 1891, $9,220.09 has been expended in repairing damages caused by the steamer City of Traverse running into the breakwater and the damages caused by winter storms. The harbor is now used to a considerable extent as a shelter from northeast storms, and its value will rapidly increase as the breakwater is extended. July 1, 1890, balance unexpended..........

(See Appendix L L 15.) 16. Milwaukee Harbor, Wisconsin.-The original depth of water at the mouth of the Milwaukee River was not more than 3 feet. The original project was adopted in 1852, and was directed to securing 12 feet of water at the entrance to the river and to protecting the channel by parallel piers. In 1868 this was modified so as to secure a channel 18 feet deep, by extending the piers 600 feet 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 of the depth of the channel by dredging. Up to the close of the fiscal year ending June 30, 1890, there had been expended on this harbor $298,843.95, in addition to $321,355.66 expended by the city of Milwaukee, resulting in the completion of the modified project of 1868. During the fiscal year ending June 30, 1891, $192 has been expended in contingent expenses. Proposals have been invited for removing about 26,000 cubic yards of material from the channel between the piers to restore it to its depth of 18 feet. |
