DESCRIPTION: Lake Montauk Harbor is located on the south fork of eastern Long Island, Suffolk County, NY. The harbor opens to the north into Block Island Sound through an inlet stabilized by two jetties. The existing Federal project at Lake Montauk Harbor provides for: a channel 12 feet deep at MLLW and 150 feet wide, extending about 0.7 miles from the 12 foot contour in Block Island Sound to the same depth in the yacht basin east of Star Island; a boat basin 10 feet deep, 400 feet wide, and 900 feet long, located northwest of Star Island; east and west jetties and; the addition of sport fishing facilities on top of both jetties. Local interests have expressed concerns about inadequate channel depths for the larger commercial fishing vessels and erosion effects in the vicinity of the inlet. The US Coast Guard has also had difficulties due to shoals in responding to emergencies from the station at Lake Montauk Harbor. Sediment transport phenomena, sand bypassing and sand management are issues to be addressed and must focus on both the inlet and adjacent shores.
