A short-pulse ground-penetrating radar system was used to determine the extent and thickness of organic-rich lake-bottom sediments in Silver Lake in south-central Connecticut. Four miles of ground-penetrating radar profiles were obtained along traverses of the frozen lake during March 1984. The radar waves penetrated 6 inches of snow, 1 foot of ice, an average of 4 to 5 feet of water, and 5 feet of soft organic and inorganic deposits. A large area of the lake bottom is underlain by soft sediment that exceeds 5 feet in thickness. No radar reflections were obtained from the hard sub-bottom in these areas because the overlying sediment likely contains large proportions of silt and clay. Coring along two radar profile lines confirmed the depths of soft sediment calculated from the radar data. Boring logs around the perimeter of the lake indicate that the eastern side may be underlain by till or poorly sorted sand and gravel, and that the rest of the lake is probably underlain by fine sand and silt, with some discontinuous layers of sand and gravel.
