AUTHORIZATION: Rivers and Harbors Act of 1913.
DESCRIPTION: It provides for a channel 10 ft. deep and at least 100 ft. wide, from East River to the dam at East 177th Street, including the widening of bends. The first dredging included a section from the East River to Randall Avenue 200 ft. wide, thence a section to Spofford Avenue 150 ft. wide, thence a section to Watson Avenue 125 ft. wide, thence a section to the railroad bridge near Westchester Ave 100 ft. wide, except to 140 ft. wide in south approach to the bridge; thereafter 100 ft. wide to head of navigation. Total length - about 3.3 miles, navigable for 2.6 miles.
COMMERCE: In 2016, 470,000 short tons of freight traffic (i.e. iron & steel scrap; sand & gravel) was transported through this navigation channel asset, compared to a five-year (2012-2016) annual average of approximately 366,000 short tons. There are two commercial facilities on this waterway, once of which, ships metal by barge and requires a 10 ft. depth (MLW). The other is a sand and gravel facility.
BACKGROUND: The channel was last dredged by the U.S. Army Corps of Engineers (USACE) in Fiscal Year (FY) 1991, when approximately 60,000 cubic yards (CYs) of maintenance dredged material was removed and disposed of at the former Mud Dump Site in the Atlantic Ocean.
STATUS: This navigation asset is currently in caretaker status, which means production of an annual hydrographic survey of the channel, and publication of a controlling depth report on the District’s website.
