IMPROVEMENT OF RIVERS AND HARBORS IN THE DULUTH, MINN., DISTRICT This district comprises northeastern Minnesota, northwestern Wisconsin, and the northern portion of the Upper Peninsula of Michigan embracing the United States waters of Lake Superior west of the head of St. Marys River and the Lake of the Woods with their tributary drainage basins. It includes Isle Royale in Lake Superior. District Engineer: Col. Schenk H. Griffin, Corps of Engineers. Division Engineer: Col. H. A. Montgomery, Corps of Engi neers. Navigation 1.

Location. The harbor is located on the south shore of Isle Royale, 55 miles northerly from the Upper Entrance to Keweenaw Waterway, Mich., and 185 miles northeasterly from Duluth, Minn. (See U. S. Lake Survey Chart No. 981.) Existing project. This provides for an entrance channel 75 feet wide and 14 feet deep, connecting the outer and inner harbors. The project depths are referred to low-water datum for Lake Superior, which is 601.6 feet above mean tide at New York. The ordinary seasonal variation of water level extends from 0 to +1 foot above low-water datum. The harbor is subject to extreme fluctuations of water level of a temporary nature, due to wind and barometric conditions, of about 1 foot above or below the mean lake level prevailing at the time. The estimated cost for new work, made in 1945, is $41,000. Annual maintenance is not required. The existing project was authorized by the River and Harbor Act approved March 2, 1945 (H. Doc. No. 446, 78th Cong., 2d sess.). Terminal facilities.-There are two small privately owned fishing wharves. Operations and results during fiscal year.-None. Condition at end of fiscal year.-No work has been done or funds expended on the existing project. A controlling depth of 6 feet for a width of 50 feet exists in the entrance channel. Proposed operations.-No funds are available and no work is contemplated during the fiscal years 1946 and 1947. Cost and financial summary Cost of new work to June 30, 1945_ Cost of maintenance to June 30, 1945. Total cost of permanent work to June 30, 1945. Net total expenditures_ Total amount appropriated to June 30, 1945. Amount (estimated) required to be appropriated for completion of existing project 2. GRAND MARAIS HARBOR, MINN. $41, 000 Location. The harbor is situated on the north shore of Lake Superior, 106 miles northeasterly from Duluth, Minn. (See U. S. Lake Survey Chart No. 9.) Existing project. This provides for rock-filled timber crib breakwater piers 350 feet in length from the east and west points of the bay to narrow the entrance; for constructing concrete sea walls across the ledge at the southeast corner of the harbor; and for dredging an anchorage area of 36.5 acres to a depth of 16 feet with depths near the entrance of 18 and 20 feet. All depths are referred to low-water datum for Lake Superior, which is 601.6 feet above mean tide at New York. The ordinary seasonal variation of water level extends from 0 to +1 foot above low-water datum. The harbor is subject to extreme fluctuations of water level of a temporary nature, due to wind and barometric conditions, of about 1 foot above or below the mean lake level prevailing at the time. The estimate of cost for new work, revised in 1935, was $209,000. The latest (1935) approved estimate of cost for annual maintenance is $6,500. The existing project was authorized by the following River and Harbor Acts: Local cooperation.-Fully complied with. Terminal facilities.-There are two general merchandise wharves, one oil wharf, and several fish wharves, all privately owned. These facilities are considered adequate for existing com merce. Operations and results during fiscal year.Maintenance surveys were made at a cost and expenditure of $100. Condition at end of fiscal year.-The existing project was completed in 1937. Project depth of 16 feet is available in the anchorage basin dredged by the United States and by private parties under permit. Under permits to private parties, 420,795 cubic yards have been dredged since 1922 without cost to the United States. No private dredging was done during the fiscal year. Project depths of 18 and 20 feet are available in the entrance channel. The concrete sea walls are in excellent condition. The breakwaters are in good condition. The gravel spit along the eastern side of the harbor is too low to prevent waves from rolling into the harbor during severe storm periods. The total costs of the existing project at the end of the fiscal year were $209,819.91 for new work and $123,961.60 for maintenance, a total of $333,781.51. The total expenditures were $333,781.51. Proposed operations.-The amount of $400 anticipated to be allotted during fiscal year 1946 will be applied to maintenance surveys during the fiscal year. An additional sum of $1,000 can be profitably expended during the fiscal year 1947 for maintenance surveys with Government plant and hired labor. Amount allotted from War Department Civil Appropriation Act approved Mar. 31, 1945_. Gross amount expended.. Amount that can be profitably expended in fiscal year ending 3. LUTSEN HARBOR, MINN. $100.00 100.00 1,000.00 Location. The harbor is located at the mouth of the Poplar River on the north shore of Lake Superior, 87 miles northeasterly from Duluth, Minn., and 19 miles southwesterly from Grand Marais, Minn. (See U. S.
