The sediments in the southern half of Cayuga Lake are generally banded. The couplets are ca. 2 cm thick at a depth of 1.5 m in the sediment and contain finer laminae approximately 1 mm thick. Major bands can be correlated over a distance of 19 km and apparently correspond to recorded periods of unusually rapid runoff or high lake levels. It is concluded that the deposition of the couplets is controlled by annual variation in the supply of allochthonous organic detritus and clastic sediment. A total of 2 × 10 11 g dry weight of clastic sediment enters the lake annually through its tributaries. Turbidity currents apparently are responsible for the distribution of a large fraction of this material in the lake.
