IMPROVEMENT OF PROVIDENCE RIVER AND NARRAGANSETT

BAY, RHODE ISLAND.

Providence River is an estuary of Narragansett Bay. The object of its improvement is to furnish a wide and deep channel for European and coastwise commerce from the ocean to Providence, a city which had in 1885 about 125,000 inhabitants, largely engaged in manufactures, and a port of entry for an extensive region of country, with which it is connected by railroads. The mean rise and fall of the lide is 4.7 feet.

ORIGINAL CONDITION.

Before the improvement of the river was commenced, in 1853, many shoals obstructed navigation, and at one point in the channel, a place called “The Crook,” the available low-water depth was but 4feet.

PLANS OF IMPROVEMENT.

There was expended between 1952 and the 30th of June, 1882, $290,459.34 in deepening the channel; first to 9 feet, then to 12 feet, then to 14 feet, and again to 23 feet, as the increasing size of vessels and the growing commerce of Provi. dence demanded. Bulkhead Rock was also removed during this period to a depth of 20 feet below mean low water.

The approved project of 1878, modified in 1882, under which we are now working, provides for a channel 25 feet deep and 300 feet wide, suitable for large ocean vessels, extending from Fox Point, in the city of Providence, 10 the deep water of Narragansett Bay, and for an anchorage basin between Fox and Fields Points of the following dimensions in cross sections, viz. :

300 feet wide, 25 feet deep.
600 feet wide, 20 feet deep.
725 feet wide, 18 feet deep.

940 feet wide, 12 feet deep.

1,060 feet wide, 6 feet deep. The 25-foot channel has been laid out in straight reaches (with enlargements at the angles) with a view to lighting them by range or leading lights, such as are used in similar cases in Chesapeake Bay, Delaware River, and other locali. ties, if it should be found necessary.

A plat of the Providence River, showing the improved channel, was published in the Annual Report of the Chief of Engineers for 1884, page 622.

AMOUNT EXPENDED AND RESULTS TO JUNE 30, 1890.

The amount expended on the present project up to the close of the fiscal year ending June 30, 1890, including liabilities outstanding at that date, was $283,600.63. At that date the 25-foot channel, 300 feet wide, had been completed. Bulkhead Rock had been removed. The excavation of the 20-foot anchorage area has been completed in Fox Point Reach, and of the same areas in the Sassafras Point and the Fields Point reaches, about three-fourths and onehalf respectively, had been finished.

The 18-foot area on the east side of Fox Point, and about three-fourths of the 18-foot area on the same side of Sassafras Point Reach had also been finished.

OPERATIONS DURING THE LAST FISICAL YEAR.

At the beginning of the last fiscal year no work was in progress.

By act of September 19, 1890, Congress appropriated $50,000 for continuing the improvement, and a project for the expenditure of this sum was prepared and was approved by the Chief of Engineers.

The project contemplates, first, the completion of the entire anchorage area in the Fox Point Reach, and, second, the expenditure of the remaining funds towards the completion of the anchorage area in Sassafras Point Reach, begin. ning with the unfinished portion of the 20-foot area; and if funds remain, dredg. ing in the 18, 12, and 6 foot areas, in the order named.

Advertisements for proposals for dredging under this project were issued November 21, 1890, and proposals opened December 22, 1990. All were rejected and the work was readvertised March 5, 1891. Proposals under this advertise. ment were opened March 25, 1891. Abstracts of proposals received under both The above advertisements and the terms of the contract will be found in the ap. pended tables.

Work under this contract was commenced April 29, 1891, and was in progress at the close of the fiscal year ; 140,673 cubic yards had been excavated up to June 30, 1891, completing the 18, 12, and 6 foot areas on the west side of the Fox Point Reach.

Work was also commenced on the 12-foot area on the east side of the same reach.

WORK REQUIRED TO COMPLETE THE EXISTING PROJECT.

There is required for the completion of the existing project the remainder of the excavation of the anchorage basin between Fox and Field Points.

OPERATIONS CONTEMPLATED FOR THE FiscAL YEAR ENDING JUNE 30, 1892.

It is proposed to apply the balance of the funds on hand and the appropriation asked for to continue the excavation of the anchorage area.

Providence River is in the collection district of Providence, which is a port of entry. The amount of revenue collected at Providence in the last fiscal year was $328,849.56. The nearest light-houses are the six ligbt-houses in Providence River. The nearest fortifications are fort on Dutch Island and Fort Adams, R. I.
