Local cooperation. The act of March 2, 1945, provided that local interests furnish, free of cost to the United States, suitable spoil-disposal areas for the initial work and for subsequent maintenance as required for dredging the turning basin between the city and the Bushman docks. Negotiations for compliance are in progress.

Terminal facilities. As the canal and connecting channel is a through waterway, the only terminal facilities are in the city of Sturgeon Bay, 4 miles from the west end of the revetted portion of the canal. These facilities consist of four coal wharves, four shipbuilding yards, and one package-freight wharf. The city of Sturgeon Bay has provided a public wharf. There is also an inactive large stone wharf located about 5 miles northwesterly from the city of Sturgeon Bay.

Operations and results during fiscal year.–Operations consisted of dredging 32,500 cubic yards of material for restoration of project depth at a cost of $9,264.35. Placing 983 tons of stone as riprap along the north pier, in progress at the close of the previous fiscal year, was completed at a cost of $2,126.26. Repairs to south revetment, including reinforcing and rebuilding of the substructure where necessary, and backfilling, in progress at the close of the fiscal year, cost $27,914.63. All work was done by hired labor and use of Government plant. The total cost was $39,305.24 for maintenance. The total net expenditures were $44,387.62.

Condition at end of fiscal year. The project in effect prior to the modification of March 2, 1945, was completed in 1942. No work has been done on the last modification of the project providing for a turning basin between the city and the Bushman docks. The harbor entrance piers were completed in 1880, and the canal revetments in 1903. Dredging and rock removal at the easterly entrance to the canal and dredging the channel in the westerly section of the canal was completed in 1940. Deepening and widening the middle section of the canal was completed in 1942.

Pile revetments require repairs and backfilling. The entrance piers are in good condition.

The controlling depth at low-water datum at the close of the fiscal year was 22 feet. The costs under the existing project were $725,303 for new work and $1,077,595.24 for maintenance, a total of

$1,802,898.24. The total expenditures were $1,811,724.93. In addition, the sum of $425,259.17 (including $189,319.35 under previous projects) was expended between April 25, 1893, and June 30, 1917, on the operating and care of the works of improvement under the provision of the permanent indefinite appropriation for such purposes.

6. ALGOMA HARBOR, WIS. Location.—Algoma Harbor is on the west shore of Lake Michigan, distant about 68 miles from Green Bay via Sturgeon Bay Canal and about 115 miles northerly from Milwaukee. (See U.S. Lake Survey Chart No. 703.)

Previous projects.-Adopted by the River and Harbor Act of March 3, 1871, and modified by River and Harbor Acts of March 3, 1873; March 3, 1875; July 5, 1884; and March 3, 1899. For further details see page 1935 of Annual Report of 1915 and page 1445, Annual Report for 1938.

Existing project.This provides for an outer harbor 14 feet deep enclosed by a north pier, 1,102 feet long, extending approximately normal to the shore, and a south breakwater, 1,530 feet long, extending from the shore at a point about 1,000 feet south of the remaining 481 feet of the pier on the south side of the channel at the mouth of Ahnapee River, and for a channel of same depth as outer harbor, except where rock is encountered at less depth, extending from that depth in the lake up the river a distance of 1,000 feet from its mouth, a total length of about 2,100 feet; this channel varies in width from 175 to 80 feet at Second Street Bridge. The piers are formed of stone-filled timber cribs and piling and the breakwater of stone-filled timber cribs, concrete caissons, and piling. The north pier and south breakwater have been provided with concrete superstructure.

The project depth is referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage and extreme fluctuations of a temporary nature, due to wind and barometric pressure, of about 112 feet above or below the mean lake level prevailing at the time.

The estimate of cost for new work, made in 1907, was $140,000, exclusive of amounts expended on previous projects. The latest (1917) approved estimate for annual cost of maintenance is $3,500.

The existing project was authorized by the following river and harbor acts:

Terminal facilities. These consist of a coal wharf and several fishing wharves. The facilities are considered adequate for existing commerce.

Operations and results during fiscal year.-Operations consisted of taking soundings, by hired labor and use of Government plant, at a total cost and expenditure of $79.83 for maintenance.

Condition at end of fiscal year.—The existing project was completed in 1909. The north pier was completed in 1890, the south pier and breakwater and dredging in 1909. The north pier and south breakwater are in good condition. The south stub pier at the river mouth is in a dilapidated condition. The controlling depths at low-water datum at the close of the fiscal year were 14.6 feet in the entrance channel to the outer end of south stub pier, decreasing to 11.5 feet to the coal wharf at the inner end of the north pier, thence 9 feet in a narrow channel to Second Street Bridge. The Ahnapee River is navigable for a distance of about 2 miles from its mouth for vessels drawing not more than 4 feet. The costs and expenditures under the existing project were $99,236.15 for new work and $245,362.07 for maintenance, a total of $344,598.22.

Proposed operations.—The balance unexpended at the end of the fiscal year ($4,500) plus an additional amount anticipated to be allotted will be applied as follows: Maintenance: Riprap breakwater and piers with United States plant, July 1945, 1,000 tons at $4.50

7. KEWAUNEE HARBOR, WIS. Location. On the west shore of Lake Michigan, distant about 105 miles northerly from Milwaukee and about 78 miles from Green Bay, via Sturgeon Bay Canal. The harbor is at the mouth of the Kewaunee River. (See U. S. Lake Survey Chart No. 73.)

Previous projects.—The original project was adopted by the River and Harbor Act of March 3, 1881. For further details, see page 1936 of Annual Report for 1915 and page 1447 of Annual Report for 1938.

Existing project.—This provides for a converging north breakwater and shore connection about 3,130 feet long, removal of about 1,400 feet of the total length of about 1,850 feet of the north pier, a south pier about 1,850 feet long, an entrance channel of a general width of 525 feet, about 2,800 feet long and 20 feet deep, leading to an interior turning basin of the same depth; also for removal of the outer south shoal to a depth of 22 feet. The parallel piers are formed of stone-filled piling and are capped with concrete superstructure. The north breakwater is formed of concrete caissons and the north-shore connection is a rubble mound.

The project depth is referred to low-water datum for Lake Michigan, which is 578.5 feet above mean tide at New York. The fluctuations of water level are seasonal changes of about one-half foot above or below the annual mean stage, and extreme fluctuations of a temporary nature, due to wind and barometric pressure,
