Lake Montauk Harbor, NY Navigation Improvement Project

For more information please read the Fact Sheet.

 

 

October 2023 update:  The recommended plan for Lake Montauk Harbor is to deepen the channel and authorize a deposition basin utilizing the Corps’ Continuing Authorities Program, Section 107.  The recommended plan is the deepening of the navigation channel to -17 ft. MLLW and creation and maintenance of a deposition basin 100 ft. wide immediately east of the channel.  Material from the initial deepening will be placed on the eroded shoreline west of the inlet jetty.  A Project Partnership Agreement for project design and construction was executed September 2022 between the Corps and Town of East Hampton.  Project design is currently underway, and project construction of the channel deepening is scheduled for Late 2024, upon Town acquisition of real estate necessary for placement of dredged material west of the inlet.
