Long Island Sound - West Chart

Long Island Sound - East Chart

Long Island Sound averages 60 ft in depth, with the greatest depth of over 300 ft at the eastern end. Tidal effects are strongest at the narrow western end, where all the inrushing water flow piles up and makes tidal variations of up to 7 ft. Strong tidal currents are also prevalent, and visibility tends to be poorer than the open ocean, especially at depth.


Beach Jetties

Dozens of jetties up and down the coast have been cut-though at the base like this one, making them inaccessible to fishermen, but not divers !
