IMPROVEMENT OF HARBOR AT DUNKIRK, NEW YORK.

REPORT OF OPERATIONS.

At the beginning of the fiscal year work of repairing structures had been commenced with hired labor and materials purchased. The work continued to December 19, 1907, when it was suspended, $12,977.09 having been expended during the season.

The repairs made were as follows:

Breakwater. Rebuilding timber back wall and deck on 860 linear feet, wrecked by storm of January 20, 1907, and also placing 660 cubic yards filling stone in this section; replacing with concrete 71 linear feet of wrecked and damaged timber lake slope; replacing broken deck plank on 481 linear feet of timber breakwater.

West pier. Rebuilding 167 linear feet of timber pier at shore end; replacing broken back wall timbers and deck plank of superstructure on the 110-foot timber section; replacing broken deck plank on the 265-foot timber section at outer end of pier.

In June, 1908, preparations were made for further repairs, and at the close of the fiscal year work had been commenced.

These repairs will consist of replacing with concrete about 80 linear feet of wrecked slope timber on breakwater, placing 435 cubic yards of filling stone in breakwater and pier, and repairing crib substructure on 50 linear feet of timber pier.

CONDITION OF THE WORKS.

Both the west pier and the breakwater are in poor condition and need repairs annually. They were damaged by storm January 20, 1907, and are liable to further damage by severe storms.

The entrance channel and harbor basin are in fair condition.

PROPOSED OPERATIONS AND REMARKS.

The work outlined in the adopted project for Dunkirk Harbor has been completed, except maintenance, which will be required indefinitely.

It is estimated that this will cost $5,000 per year, and $10,000 should be appropriated for two years' maintenance.

The commerce of Dunkirk is small and is not increasing.

Extension of Stony Point section of breakwater. This extension to have a length of 1,000 feet, running in a northwesterly direction Total... h end of the present Stony Point section, at an angle from the axis of said section, and built of stone; it is

'h entrance arm."

This was raised to a height of 12 feet below mean lake level with stone excavated from Lake Erie entrance to Black Rock Harbor and Erie Basin, and a contract was made with the Canal Quarry Company, of Buffalo, May 31, 1906, for completion of so much of it as the funds then available, approximately $130,000, would allow. Work under this contract has been in progress during the fiscal year and is now only about one-fourth completed.

Stone superstructure, sea slope, and riprap on South Harbor section of breakwater.-Contract of C. M. Handy for this work called for completion December 31, 1906, but this time limit was waived, and the work completed October 2, 1907, at a cost, exclusive of office and engineering expenses, of $101,805.43, the amount of $621.66 having been deducted for expenses incurred by reason of delay in completion.

Under this contract 723 linear feet of wrecked timber breakwater was rebuilt in permanent rubble mound form.

Repairs to breakwater damaged by storm of January 20, 1907.-A severe wind storm on January 20, 1907, damaged the old section of the breakwater for a distance of 1,910 feet, the timber superstructure being practically destroyed. Damage was also done to the decks and walls on other portions of the timber breakwater.

An appropriation of $350,000 was made by the river and harbor act of March 2, 1907, to repair this damage.

A project was submitted and approved for placing a stone-concrete superstructure on the 1,910-foot section of the old breakwater, and a contract was made May 31, 1907, with the Great Lakes Construction Company, of Buffalo, the lowest bidder, for this work.

Work under this contract has been in progress during the fiscal year. Fourteen thousand eight hundred and eighty-five cubic yards capping stone and 4,443.5 cubic yards rubblestone have been placed, none of the superstructure being fully completed.

The storm wrecked the middle and banquette decks on the Stony Point section of the breakwater. The wrecked timberwork was removed by day's labor to the level of the banquette on the outer 900 linear feet of structure, and a covering of large rubblestone was laid on the cribwork behind the parapet.

"An emergency contract was made with the Canal Quarry Company July 15, 1907, for depositing 8,000 tons of this large stone on the Stony Point section and as riprap along the lake side of the old section of breakwater, the work to be completed December 1, 1907.

At the date for completion the contractors had deposited only 4,605.4 tons of stone, and as the time limit had not been waived nor application for extension made, the contract became terminated by its own terms.

Repairs to decks of the timber portions of breakwater damaged by the storm were made July 1 to October 11, 1907, at a cost of $7,502.98 for material and labor.

Dredging at south end of harbor.-The river and harbor act of March 2, 1907, appropriated $25,000 for dredging at entrance to canals at South Buffalo, in outer harbor.

A project for this work was submitted and approved and contract was made with the Buffalo Dredging Company, the lowest bidder, June 12, 1907, for the work.
