IMPROVEMENT OF HARBOR AT CHATHAM, MASSACHUSETTS.

Chatham Harbor is at the eastern end of Nantucket Sound, about 15 miles east of Hyannis, Mass. Its outer anchorage, known as Chatham Roads, is a capacious, deep, unobstructed harbor of refuge from northerly and easterly gales.

The inner harbor, locally known as “Stage” Harbor, is small, but well land-locked. It is about one-half mile long, 500 to 600 feet wide, and has 8 to 12 feet depth at mean low water. Its entrance is obstructed by three bars, on which the depth at mean low water does not exceed 4 feet. The mean rise or fall of the tide is 5 feet.

The project for the improvement of the inner harbor was submitted December 19, 1890, and was based on a survey made in October, 1890. It proposed to dredge a channel 6 feet deep at mean low water through the three obstructing bars, 100 feet wide at the inner bar, 150 feet wide at the middle bar, and 200 feet wide at the outer bar, at an estimated cost of $10,000.

But one appropriation has been made for this improvement, viz, by the act of September 19, 1890, $5,000.

This sum it is proposed to expend in dredging a channel 100 feet wide and 6 feet deep through the three bars.

Bids for this work were invited by public advertisement, dated January 10, 1891, and the proposals received were rejected as excessive.

The work was again advertised under date of July 10, 1891, and on August 10, 1891, the two bids received were opened. An abstract of them will be found in the annexed table.

The lowest bid was not in accordance with the specifications and was rejected. A contract was entered into with Mr. Charles W. Anthony, of Fall River, Mass., on August 26, 1891.

Operations under this contract were commenced in October, and the work was satisfactorily completed in December, 1891. Eight thousand seven hundred and ninety-four cubic yards of material were removed from the middle and inner bars, and at the date of this report the improved channel across them is 6 feet deep at mean low water and 100 feet wide. At least 5 feet at mean low water can now be carried into the inner harbor.

To complete the improvement will require an appropriation of $5,000, all of which could be expended to advantage during the fiscal year ending June 30, 1894. .

Chatham Harbor is in the collection district of Barnstable, Mass., of which Barnstable is the port of entry; the nearest light-house is Hardings Beach Light.

The accompanying commercial statistics have been furnished by the collector at Barnstable, Mass.:

This office has been assisted by Assistant Engineers Edward Parrish, John H. Rostock, and Superintendent Walter C. Simmons. Very respectfully, your obedient servant,

HARBOR OF REFUGE AT HYANNIS, MASSACHUSETTS.

The harbor of Hyannis lies on the south shore of the peninsula of Cape Cod, about 15 miles to the westward of the heel of the cape, and is an important harbor of refuge. (For map see page 592, Annual Report of 1884.)

The mean rise and fall of the tide is about 38 feet.

ORIGINAL CONDITION.

Before improvement it was an open roadstead, exposed to southerly storms, with depths varying from 10 to 20 feet in the inner harbor.

In the years 1827–1838 a breakwater of riprap granite, 1,170 feet long, was constructed, covering an anchorage of about 175 acres, the entrance to which had a depth of about 154 feet. In the years 1852–1882 extensive repairs were made in increasing the width of its base and the size of the stone forming its sides and top. About $124,000 was spent on this work, completed in 1882.

PLAN OF IMPROVEMENT.

The depth of water immediately inside the breakwater being insufficient for many vessels that now seek the harbor of refuge, the present project of 1884 for the improvement of the harbor, published in the Report of the Chief of Engineers for 1885, volume 1, pages 560 and 619-621, contemplates dredging the area protected by the breakwater to a depth of 15 feet at mean low water, at a total cost, as estimated in 1884, of $45,743.20, including the $81.20 then left over from past appropriations.

APPROPRIATIONS.

Upon the present project appropriations have been made as follows: On hand 1881, $81.20; 1886, $10,000; 1888, $10,000; 1890, $8,000. Totals up to June 30, 1891, $28,081.20.

AMOUNT EXPENDED AND RESULTS TO JUNE 30, 1891. The total amount expended on the present project (including $3,237.03 of outstanding liabilities) up to June 30, 1891, was $26,066.20. The 154foot anchorage area had been increased by about 11 acres, about onethird of the entire area to be dredged.

OPERATIONS DURING THE LAST FISCAL YEAR.

Value of United States plant, $8,400. Including $5.60 of outstanding liabilities the expenses of the year were $2,015.

At the beginning of the last fiscal year work was in progress with plant consisting of the dredge Texas and two scows belonging to the United States, and a hired tug. Six thousand three hundred and sixty cubic yards were excavated during the year, which added about 1.1 acres to the 15-foot anchorage area. Work in the field was stopped on July 16, and the plant was then transferred to other localities.

This work was in the local charge of Mr. C. O. Abell as superintendent.

WORK REQUIRED TO COMPLETE THE EXISTING PROJECT.

The work required to complete the existing project is the completion of the dredging to a depth of 154 feet over 23 acres more in the area limited on the west by a line running due north from the western end of the breakwater, and on the north by a line running parallel to the breakwater, and distant 1,500 feet from it, leaving a berm of 100 feet along its northern side.

OPERATIONS CONTEMPLATED FOR THE FISCAL YEAR ENDING JUNE

30, 1893.

It is proposed to apply the balance on hand and the funds asked for to the execution of the project above referred to—of deepening the anchorage area inside the breakwater.

Hyannis Harbor is in the Barnstable collection district, and Barnstable is the nearest port of entry. The amount of revenue collected at Barnstable in the last calendar year was $1,528.78.

The main value of the harbor is for a harbor of refuge. The nearest light-house is Hyannis Light; the nearest fortification is the fort at Clarks Point, New Bedford, Mass.
