DESCRIPTION: Two existing rehabilitated rock jetties, a rock revetment, and an entrance channel, 10 feet deep (MLW datum), 200 feet wide, from that depth in the Atlantic Ocean into the Shinnecock Bay, length approximately 0.7 mile; an inner channel, 6 feet deep, 100 feet wide, to the Long Island Intracoastal Waterway Channel, length approximately 1 mile; and a sand deposition basin that consists of a basin 20 feet deep (MLW datum), 600 feet wide and 600 feet long starting approximately 200 feet south from the southern end of the west jetty. It then widens through a 100-foot-long section up to an 800-foot-width, this 800-foot-wide section is approximately 2,100 feet long; with all dredged material from the periodic maintenance dredging of the navigation channel placed along the Atlantic shoreline west of the west jetty. This project is cost-shared with the State of New York. AUTHORIZATION: Adopted by the Rivers and Harbors Acts of 1960.
COMMERCE: Although it does not have any commercial navigation transitting this asset, the inlet is second only to Montauk as a NY commercial fishing center. Average 10 Million pounds of fish landings per year valued at $8 Million include 39 species, primarily bluefish, angler, and skate (Fishing Ports of the Mid-Atlantic 2000). The inlet is regularly used by 30-40 commercial fishing vessels, deep sea charter fishing boats, head boats. $250 thousand of boat slip revenues. Commerce not reflected in OMBIL. Critical Harbor of Refuge.
STATUS: During FY18, the project will be in caretaker status including monitoring of the channel shoaling conditions, coordination with the users and stakeholders. Funds will be used for caretaker activities and to begin preliminary Engineering and Design.
BACKGROUND: During FY2013, the channel was last maintenance dredged to full dimensions with all the sand dredged material used to restore the adjacent barrier island. Previously, the navigation channel was maintenanced dredged in FY2010 and FY2004 with all sand dredged material being placed at Tiana Beach to prevent loss of the barrier island there and for the beneficial use of continued down drift shoreline nourishment.
