At the beginning of the fiscal year the work of repairing 50 linear feet of the outer end of the west pier under contract with the Great Lakes Construction Co. was in progress, the wrecked cribwork having been removed and the foundation nearly prepared for sinking the new crib in place.

The foundation was completed and the crib sunk in place July 16, 1910; the mass concrete superstructure was placed and all work under the contract completed August 16, 1910, total cost $4,676.98, exclusive of engineering and contingencies. Minor repairs were made to decks of breakwater and pier during July and August, 1910, at a cost of $162.02 for labor and materials. No other work was done during the fiscal year.

Specifications for removal of rocky reef bordering on the inner entrance channel to a depth of 18 feet at mean lake level were prepared and approved, in anticipation of the construction of a suitable concrete dock by the local authorities, or other terminal facilities approved by the Secretary of War, this being the condition under which the funds were appropriated by the river and harbor act of June 25, 1910.

At the close of the fiscal year the conditions had not yet been complied with.

CONDITION OF THE WORKS.

The timber sections of the west pier, one 110 and one 216 feet long, and the old timber part, 1,341 feet long, of the breakwater are in poor condition and need repairs annually, owing to damage by

storms.

Examination made June 21-25, 1910, showed:

Outer entrance channel, from deep water in the lake to the elbow in the breakwater, not less than the required depth of 19 feet at mean lake level, for full width, except over a shoal area about 400 feet long on the west channel line, lakeward from Dunkirk Pierhead Light, and extending into the channel from that line about 150 feet. The least depth on the shoal is 15 feet, and the remainder of the channel along the easterly side of the shoal, 100 feet wide, is 19 feet deep at mean lake level.

Inner entrance channel, from the breakwater elbow to the harbor basin, not less than the required depth of 18 feet at mean lake level. Harbor basin, required depth of 18 feet at mean lake level, has shoaled so that the general depth is now 17 feet in the north half of the basin and 16 feet in the south half.

PROPOSED OPERATIONS AND REMARKS.

The project for improvement is completed, except the additional channel excavation provided for conditionally by the special appropriation in the river and harbor act of June 25, 1910.

Maintenance will be required indefinitely; but repairs to maintain the pier and breakwater in fair condition, unless damaged by severe storms, can be made with funds on hand.

No estimate of funds is therefore made for the fiscal year ending June 30, 1913.

APPROPRIATIONS AND ALLOTMENTS.

Extension of Stony Point section of breakwater.-Length, 1,000 feet, running in a northwesterly direction from the north end of the present Stony Point section, at an angle of 150° from the axis of said section, and built of stone; it is called the "south entrance arm."

The foundation, to a height of 12 feet below mean lake level, was made by dumping stone excavated from Lake Erie entrance to Black Rock Harbor and Erie Basin. The construction of the stone breakwater upon this foundation was begun in 1906 under contract with the Canal Quarry Co. to the extent permissible with $130,000, the amount. available at the time of making the contract. Work under this contract, time limit waived, was continued during the fiscal year until April 15, 1910, when permissible work was completed. Under this contract 616 linear feet of stone structure was completed and 184 linear feet additional built to varying heights up to 12 feet above
