Long Island Sound FactsGo Back
The Soundís surface water area is 1300 square miles.
The Sound is 21 miles wide at its widest point and 113 miles long.
Depths vary greatly in Long Island Sound, averaging 63 feet deep with a maximum depth of 320 feet at the Race.
The volume of water in Long Island Sound is estimated to be 18 trillion gallons.
There are 217 miles of direct shorefront on Long Island Sound, but including land fronting on the estuaries draining into the Sound and tidal wetlands, the entire coastal frontage measures 583 miles.
Of the stateís total frontage on Long Island Sound, 84.5 miles is sandy beach; the rest is bedrock, marsh, glacial drift, or artificial fill.
The maximum tidal range (difference between high tide and low tide) is 2.3 feet in Noank and 7.4 feet in Greenwich.
Since 1980, over 1,500 acres of tidal wetlands have been restored.
There are over 120 species of finfish in the Sound; at least 50 species spawn in the Sound.
Through implementation of the stateís Coastal Managment Program in 1980, approximately 11 miles of additional public access to Long Island Sound have been gained.
Based on the census, over 95% of the stateís population lives within 50 miles of Long Island Sound.
Almost 40% of the stateís population lives in Connecticutís 36 coastal towns and cities which occupy only 20% of the stateís land area.
Connecticutís coastal area extends to the head of salt water influence on Connecticutís tidal rivers to Shelton and Orange on the Housatonic River, Hamden and North Haven on the Quinnipiac River, Chester and Lyme on the Connecticut River, and Norwich on the Thames River.
The value of commercially harvested oysters from Long Island Sound was estimated to be $60 million in 1995 ranking Connecticut first in the nation in the total value of oysters harvested and second in oyster production among all coastal states. Norwalk is considered Connecticutís Oyster Capital based on weight of catch.
Approximately 750,000 recreational fisherman use the Sound.
500,000 boats are registered Sound-wide, and it is estimated that 30,000 to 50,000 boats are on the Sound on a nice summer day.
