to the public. There are two commercial wharves on Annisquam River on the east bank. These facilities are considered adequate for the existing commerce of the port. For full description see Port and Terminal Facilities at the Ports of Northern New England, 1941. Operations and results during fiscal year. A condition survey, by hired labor, to determine the extent of shoaling in the 8-foot channel in the Annisquam River was completed during the fiscal year. Costs were $1,916, all for maintenance. Condition at end of fiscal year. The existing project was about 77 percent complete. The existing project was completed in 1936 except for dredging the anchorage area in Lobster Cove in the Annisquam River. The removal of all ledges and boulders in Gloucester Harbor between Harbor Cove and Pews Wharf, and other obstructing rocks was completed in 1894; and the removal of a pinnacle rock in the outer harbor in 1896. The breakwater, which was completed in 1905, was repaired in 1940 and is in good condition. The removal of all ledges to project depth was completed in 1916. The improvement of Annisquam River was completed in 1936 at a cost of $33,976. The controlling depths over the ledges in the outer harbor in 1916 were from 18 to 25 feet; over ledge C in the inner Harbor in 1931, 14 feet; and over ledges A and B in the inner Harbor in 1940, 13 and 15 feet respectively; 7 feet in the channel from Ipswich Bay to Gloucester Harbor with the exception of encroachments on the west side of the channel abreast Pearce Island having a depth of 0 feet, and on the east side of the channel just north of Rust Island having a depth of 2 feet (1953), 5 feet in the northwesterly third and +5 feet in the remaining part of the Lobster Cove anchorage. The costs under the existing project have been $713,110, of which $535,154 was for new work and $177,956 was for maintenance. Other new work data: Estimated additional amount needed to be appropriated for completion of existing project........... Includes $21,000 for new work for previous projects. $169,846 12. BOSTON HARBOR, MASS. Location. This harbor includes all the expanse of tidewater lying within a line from Point Allerton to Point Shirley and extending from that line westward to the mainland. This comprises an area of about 47 square miles, exclusive of the islands. (See U. S. Coast and Geodetic Survey Charts Nos. 246 and 248.) Previous projects.

Local cooperation. Fully complied with. Terminal facilities. There are 183 wharves and piers in the Harbor, not including the Mystic River, Weymouth Fore River, and Town River, which are reported elsewhere. In addition, there are 4 ferry slips and 2 car floats. Of the terminals, 28 are publicly owned, 3 are open to public use, 77 have mechanical handling facilities, and 57 have railroad connections. The facilities are considered adequate for the present requirements of commerce. (For the latest full description of Terminal Facilities, see Port Series No. 3-the Port of Boston, Mass., revised 1946.) Operations and results during fiscal year. Maintenance dredging, by contract, to restore project depth in the 30-foot Chelsea River channel, in progress at the beginning of the fiscal year, was completed on July 28, 1953. During the period a total of 35,076 cubic yards of ordinary material were removed. Snagging operations, by hired labor, were carried on throughout the year. Miscellaneous inspections and reports were made on the project during the year. The total costs were $52,384, all maintenance funds. Condition at end of fiscal year. The existing project is about 84 percent completed, the remaining portion consisting of dredging the extension of President Roads Anchorage 700 feet to the north and 500 feet to the west at a depth of 40 feet, and dredging an area to 35 feet lying west of the anchorage; and the completion of the 40-foot main ship channel to project width for a distance of about 4,000 feet along the east side at the upstream end of the project. The seawalls have a total length of about 3.75 miles and have been built and maintained on Great Brewster, Lovells, Gallups, Long, Rainsford, Deer, and Georges Island and on Point Allerton.

Location. Dorchester Bay is situated at the mouth of Neponset River, in Boston Harbor. Neponset River rises in Foxboro, Mass., and flows in a northeasterly direction about 25 miles, emptying into Dorchester Bay. (See U. S. Coast and Geodetic Survey Chart No. 246.) Existing project. This provides for a channel 25 feet deep and 300 feet wide from the Boston Harbor main ship channel to Commercial Point, thence 15 feet deep and 100 feet wide to the Neponset Highway Bridge. The project depths refer to mean low water. The mean range of tide is 9.6 feet and the extreme range is 13.7 feet. The estimate of cost for new work (1954) is $770,000. The latest (1950) approved estimate for annual cost of maintenance is $7,000. The existing project was authorized by the following River and Harbor Acts: The act of March 2, 1907 (H. Doc. 83, 59th Cong., 2d sess.), provided for the 15-foot channel, and the act of March 2, 1945 (H. Doc. No. 394, 77th Cong., 1st sess.), provides for the 25foot channel. The latest published map is in the last project document. Local cooperation. Conditions were imposed by the act of March 2, 1907, that the portion of the river from Neponset Highway Bridge to Milton Mills should be dredged and maintained by the Commonwealth of Massachusetts or other agency to the depth of 6 feet at mean low water, 100 feet wide up to the Granite Street Bridge, 1.15 miles; 75 feet wide thence to Godfreys Wharf, 1.25 miles; and thence 50 feet wide to the railroad bridge at Milton, a distance of 250 feet. These conditions were accepted by resolves of the Legislature of Massachusetts, approved June 24, 1907, and March 5, 1908. The river was dredged by the Commonwealth of Massachusetts in 1910 and has been maintained periodically by the Commonwealth since that date. Terminal facilities. There are 16 wharves located on these waterways which are used for commercial purposes. |
