igan 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, 1891, was $164,969.65, resulting in the completion of the piers as projected, and in a dredged 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, 1892, there was expended $1,803.75 in repairs to piers and in dredging, which resulted in a channel 16 feet deep and 120 feet wide from the 16-foot contour in Lake Michigan to the canal entrance.

Soundings taken in April, 1892, show that the governing depth has been reduced by deposits of material to about 12 feet.

The restoration of the channel to a depth of 16 feet was begun June

21, 1892, and is in progress at the close of the fiscal year.

10. 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 artificial 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, 1891, was $161,208.66, 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, 1892, $4,032.14 has been expended in placing a double row of sheet piling along 352 feet of the north pier and removing 652 cubic yards of rock and 28,205 cubic yards of sand and gravel from the channel. The rock was used for refilling and riprapping the piers.

Soundings made in October, 1891, showed a depth at the entrance of 16 feet, and thence to the west end of the piers 12 feet.

The Ahnapee and Western Railroad to connect with the Green Bay and Western Railroad is expected to be completed and in operation this season.

11. 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, 1891, was $63,885.14, 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 there was a channel 120 feet wide and 14 feet deep.

During the fiscal year ending June 30, 1892, $10,736.79 was expended in extending both piers, the north pier being now 1,250 feet long and the south pier 1,125 feet long. This work was completed September 17, 1891.

Soundings taken in April, 1892, show the governing depth in entrance. channel to be about 11 feet.

The completion in October, 1891, of a railroad between Kewaunee and Green Bay, forming with existing railroads and a line of steamers plying across Lake Michigan between Kewaunee and Frankfort, Mich., a through route of transportation between the Missouri River and the • Atlantic seaboard, has greatly increased the importance of this harbor. Two steamers for the carriage of twenty-four cars each between Kewau nee and Frankfort are to be completed and delivered September 1. They are 256 feet over all, 54 feet beam, and are expected to draw 12 feet of water.

12. 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, 1891, was $202,639.02, which was expended in the construction of two parallel piers, the north and south piers being 1,810 and 1,710 feet long, respectively, in dredging, and in repairs to the piers.

There was no work done during the last fiscal year.

A survey completed in May, 1892, showed a channel about 50 feet wide and 9 feet deep.

13. 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, 1891, was $302,806.41, resulting in the construction of two piers, the north one 1,970 feet and the south one 1,900 feet long, 228 feet apart at the shore line and 250 feet at the outer ends; renewal of superstructure of piers, and in the removal of 194,462 cubic yards of material by dredging.

During the fiscal year ending June 30, 1892, $4,260.97 has been expended in rebuilding 342 feet of superstructure of the north pier and in dredging 2,429 cubic yards of material from the channel.

Soundings taken in April, 1892, showed a depth of water at entrance of 16 feet, and a navigable channel, midway between the piers, about 141 feet deep.

14. 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 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, 1891, amounted to $305,863.28, resulting in the construction of a north and a south pier, 2,120 and 2,387 feet long, respectively, and the removal by dredging of 232,518 cubic yards of material.

[ocr errors]

In April, 1891, there was a channel about 50 feet wide, with a least depth of 14.3 feet. Dredging was begun in June and completed in August, 1891. Seventeen thousand and thirty cubic yards of material was removed during the fiscal year.

There was expended during the fiscal year ending June 30, 1892, $12,392.75 in pier extension and dredging. The north and south piers are now 2,270 and 2,387 feet long, respectively.

A survey, made in April, 1892, showed a governing depth of water in the channel to be about 13.7 feet.

15. 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 53 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, 1891, was $174,473.20, and resulted in the construction of a north and south pier, 920 and 1,226 feet long, respectively, 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 2 and 3 acres, respectively. The north basin had a depth of 12 feet over nearly its entire area, and a narrow channel 12 feet deep from abreast the inner end of the north pier to the upper end of the west basin, although the average depth did not exceed 8 feet.

There was expended during the fiscal year ending June 30, 1892, $2,901.34 in dredging 14,360 cubic yards of material from the entrance channel and basins, and refilling and riprapping cribs of the piers with about 40 cords of stone.

Soundings taken in May, 1892, indicated a ruling depth of water in the entrance channel of 10 feet.

16. 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 a 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. The actual length of the breakwater when completed will be 7,250 feet.

Work began in 1881, and up to June 30, 1891, there had been expended $404,121.81, 3,650 feet of substructure, and 3,325 feet of superstructure being completed.

During the fiscal year ending June 30, 1892, 500 additional feet of substructure and 525 feet of superstructure were added at an expenditure of $65,022.71, including cost of care, repairs, and lighting. There remain to be constructed 3,100 feet of substructure and 3,400 feet of superstructure to complete the work.

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.

17. Milwaukee Harbor, Wisconsin.-The original depth of water at the mouth of the Milwaukee River was not more than 33 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 expendi tures 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, 1891, there had been expended on this harbor $324,627.85, 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, 1892, $5,752.62 has been expended for dredging between the piers to a depth of 18 feet for a width of 162 feet.

Soundings taken in May, 1892, show that a deposit of material has
