Line 4:
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 15,000 [[Before Present|BP]] and subsequent refreshening, as [[sea level rise|rising sea levels]] and [[isostatic rebound]] of land depressed by the former weight of ice sheets adjusted to one another.
