Results from a field investigation of seasonal variations in turbidity are presented for a narrow (≈12 × ≈1 km) glacial Finger Lake south of Rochester, N.Y. The turbidity structure is primarily vertical in summer and under winter ice cover; during spring and fall mixing horizontal gradients dominate. Inflows from the large drainage area at the southern end of the lake show a Coriolis influence. Vertical mixing of this inflow correlates well with density. During most of the year turbidity seems to be associated principally with suspended inorganic material.
