Glacial '''Lake Connecticut''' formed over what is now [[Long Island Sound]] and coastal [[Connecticut]] at the fore edge of the ice sheet of the [[Wisconsin glaciation]], as the lobe of the [[Laurentide ice sheet]] began to retreat, some 18 to 20,000 years before present. It was dammed by the [[terminal moraine]] that now forms the spine of [[Long Island]] and [[Fishers Island]]. About 15,000 [[Before Present|BP]], the moraine dam that impounded Lake Connecticut failed; the outlet, known as The Race for its tidal [[rip current]]s, lies between the [[North Fork, Suffolk County, New York|North Fork]] of Long Island and Fishers Island. For a time, much of the lake bed was exposed to wind-driven erosion: the cue is found in soundings that reveal regional [[Unconformity|unconformities]] in the sediment bed of Long Island Sound.▼

The fore-edge lake formed by glacial meltwater expanded to be about the same size as present-day Long Island Sound; it may have been connected at times with similar freshwater lakes in [[Block Island Sound]] and [[Buzzards Bay]], while sea level was low. The fairly shallow average depth of 78 feet (24 m) of today's Long Island Sound is the result of fine lake-bottom sediments deposited as glacial outwash slowed in Lake Connecticut. Suspended as [[rock flour]], the fine sediments would have rendered Lake Connecticut a turquoise blue-green.
The end of Lake Connecticut was marked by a series of intervals of salt water incursion after about
