1. CHIPPEWA HARBOR, ISLE ROYALE, MICH. 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 harometric 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.

2. GRAND MARAIS HARBOR, MINN. 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:

[blocks in formation]

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 commerce.

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.

3. LUTSEN HARBOR, MINN. 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. Lake Survey Chart No. 97.)

Existing project. This provides for two converging breakwaters extending from the shore on either side of the mouth of the Poplar River 150 feet apart at their outer ends, having lengths of 240 feet and 425 feet for the east and west breakwaters respectively; for a flared entrance channel between the breakwaters 12 feet deep with a minimum width of 60 feet extending from that depth in the lake to the mouth of the river; for an inner channel on the east, 100 feet wide and 8 feet deep, with a length of 215 feet; and for an inner channel on the west, 50 feet wide and 6 feet deep, with a length of 255 feet.

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 Federal cost for new work, made in 1945, is $66,800, and $66,785 is to be contributed by local interests. The latest (1945) approved estimate of cost for annual maintenance is $1,000.

The existing project was authorized by the River and Harbor Act approved March 2, 1945 (H. Doc. No. 446, 78th Cong., 2d sess.). This document contains the latest published map.

Local cooperation. The improvement authorized by the act of March 2, 1945, is subject to the requirement that local interests

(1) Contribute $66,785 in cash toward the cost of protective structures and dredging.

(2) Provide and maintain, without cost to the United States and in accordance with plans approved by the Chief of Engineers, a suitable and adequate public wharf for the accommodation of transient vessels.

(3) Establish a competent and properly constituted public body empowered to regulate the use, growth, and free development of harbor facilities (exclusive of Federal property) with the understanding that harbor facilities shall be open to all on equal and reasonable terms.

(4) Hold and save the United States free from damages due to the construction and maintenance of the works.

(5) Provide, without cost to the United States, all lands, easements, and rights-of-way necessary for the construction of the project, including suitable spoil disposal areas when and as required.

It is further provided that no work shall be done by the United States at this harbor until the prescribed requirements for local cooperation have also been complied with at the following additional project in this area: Beaver Bay Harbor, Minn.

None of the above requirements have been complied with.

Terminal facilities.—No terminal facilities have been constructed.

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 1 foot exists over the bar at the mouth of the Poplar River.

Proposed operations.—No funds are available and no work is contemplated during the fiscal years 1946 and 1947.
