Federal Navigation Channel- Maintenance of Infrastructure and Stewardship

Bookmark and Share Email Print

DESCRIPTION: Mattituck Inlet is located on the Long Island Sound in the town of Southold, NY.  The existing federal navigation project provides for a channel, 7 feet deep, from the Long Island Sound to the Village of Mattituck in the Town of Southold, 100 feet wide at the entrance and 80 feet wide thereafter.  There are two riprap jetties at the entrance. The east jetty was completed in 1906 with a length of 775 feet.  The original navigation channel construction was completed in 1914.  The west jetty was completed in 1938.

AUTHORIZATION: Adopted in 1896, modified in 1935 and 1964.

COMMERCE: Mattituck is a vibrant fishing, boating and recreation site along the Long Island Sound and provides safe navigation from the Long Island Sound through Mattituck Inlet.   It is also a Critical Harbor of Refuge. Two jetties are the aids to navigation currently in operation. As a result of past jetty construction, the west jetty fillet fills in rapidly while the down-drift beach is sand-deprived. Monitoring the conditions periodically is the minimal reasonable stewardship for this asset. 

STATUS: In April 2014, the Mattituck Inlet channel was used as a sand source for a beach nourishment project where approximately 100,000 cubic yards of sand was dredged and placed at Baillie Beach Park in Mattituck, NY. The Inlet channel was previously dredged in March 2004, with approximately 14,000 cubic yards of sand placed as beneficial use of material along the Baillie Beach Park shoreline.  During June 1996, the west jetty rehabilitation was completed.
