Federal Navigation Channel

Bookmark and Share Email Print

DESCRIPTION:  The existing Moriches Inlet Federal Navigation Project provides for a channel, 10 ft. deep, 200 ft. wide, extending from that depth in the Atlantic Ocean to Moriches Bay, at a length of approximately 0.8 mile, and a channel, 6 ft. deep, 100 ft. wide, to the Long Island Intracoastal Waterway, length approximately 1.1 miles.  In addition, the project includes a deposition area at the entrance of the channel, 14 feet deep plus 2 feet overdepth, 350 feet wide, and 3,000 feet in length.  This project is cost-shared with the State of New York.

AUTHORIZATION/PROJECT DESCRIPTION:  The Moriches Inlet Project was authorized by the Rivers and Harbors Act of 1960 and the 1985 Supplemental Appropriation Act.     COMMERCE:  Authorized critical Harbor of Refuge and critical USCG Search and Rescue Station inside the inlet.  USCG receives on average 1000 calls for help on the South Shore of Long Island each year.  Moriches is one of 6 coastal inlets providing access to the Atlantic Ocean.  

STATUS:  During this FY, continued monitoring of the conditions of the Federal channel will be performed and a Controlling Depth Report will be published.  Coordination with local stakeholders will also continue.   The inlet was used as a borrow source of sand to close the breach at Cupsogue Beach that was created by Hurricane Sandy.  Approximately 200,000 CY of sand were removed from the inlet for this effort.   The last maintenance dredging cycle occurred during the winter of 2009.  Approximately 460,000 CY of material was removed by Suffolk County Department of Public Works and placed at Cupsogue Beach, Smith Point and other areas.   Prior to this last cycle, maintenance dredging of the inlet was last performed by the USACE in February 2004 using Federal/non-Federal cost-share funds.  Approximately 250,250 cubic yards of material were removed from the channel and deposition basin and placed along the shoreline west of the jetty.    The most recent condition survey of the Inlet and Controlling Depth Report is located on the webpage below.
