IMPROVEMENT OF ONTONAGON HARBOR, MICHIGAN.

Original estimates (see Report of the Chief of Engineers, 1867, page 20).. $363, 770 Appropriated 272, 600

The project for the improvement of this harbor consists in the construction of two parallel piers, 250 feet apart, extending from the mouth of the Ontonagon River in a north westerly direction to the 18-foot curve

5908 EN -115

in Lake Superior, with a channel between the piers affording a depth of 12 feet at low water, connecting the deep water in the lake with the deep water in the river.

Operations under this project were begun in 1867.

At the close of the fiscal year ending June 30, 1883, the work of extending the east pier was in progress, under a contract with Joel Rich, of Ontonagon, and 200 linear feet of superstructure had been built and one crib sunk by him at that date.

During the last fiscal year, under the same contract, the east pier was extended 250 feet, by sinking 5 cribs, each 50 feet long, 20 feet wide, and 123 feet deep; 200 linear feet of superstructure was built over cribs Nos. 51 to 54, which had been sunk the previous year in extension of the east pier, and the outer crib, No. 60, was planked over, completing the contract.

By hired labor and purchase of materials in open market planking was placed on cribs Nos. 56 to 59 (inclusive); a length of 200 feet of the east pier and 20 snubbing posts were placed in the east and west piers. The condition of the harbor is now as follows:

The east pier is 2,265 feet in length, and projects 200 feet further into the lake than the west pier, which is 2,275 feet in length.

On the outer 300 feet of the east pier six courses of superstructure are yet to be built, and on the outer 650 feet of the west pier two courses of superstructure are to be built. The necessity of completing this superstructure is urgent.

Soundings taken between the piers and on the outer bar in September, 1883, showed the existence of a channel about 12 feet deep at low water and with a least width of 100 feet.

As stated in the last annual report on the improvement of this harbor: The formation of a bar in the vicinity of the outer entrance to the piers reduces the available depth to something usually less than 11 feet. The dredging which has been done at this harbor was applied toward deepening the channel through the outer bar; the work was of but temporary relief. Rapid pier extension to the deep water of the lake seems to be the only permanent method of overcoming the difficulty.

It is highly probable that in the near future the pile-pier, or revetment, near the inner end of the west pier will require a sand-tight lining similar to that applied to the pile-pier at Ahnepee and Sturgeon Bay harbors; the present condition of the revetment is such as to permit large quantities of sand to pass into the channel between the piers, and this sand, carried by the current outward, probably hastens the formation of the outer bar.

It is proposed to apply the appropriation of $15,000 made in July, 1884, to pier construction.

The work contemplated during the fiscal year ending June 30, 1886, is the further extension of the piers.

IMPROVEMENT OF EAGLE HARBOR, MICHIGAN.

Modified estimate (see Report of the Chief of Engineers, 1876, II, 328, 1877, I, 98, II, 845).

Appropriated

$97,000 97,000

The modified project for the improvement of this harbor by blasting a channel 130 feet wide and 14 feet deep at low water, through the rocky reef which obstructed the entrance, and by sinking two guiding cribs to mark the new channel, was completed in 1879.

The balance of funds on hand will be applied, when necessary, to the preservation of the cribs and channels.

There were no operations during the year ending June 30, 1884.
