Little is known about the current circulation on small bodies of water. Previous data on surface currents in Douglas Lake were published by Gannon and Fee (1970). That investigation revealed an eastward drift which dominates the surface movements in the lake with clockwise eddies east of Fairy Island and in South Fishtail Bay. They hypothesized that "the set-up of water over the lake due to the westerly wind is most likely dissipated as surface seiche activity and possibly as subsurface returen currents ins ome areas." A subsurface return current in South Fishtail Bay was revealed in a study by Gannon and Brubaker (1969). This paper deals with an investigation of the surface and epilimnion circulation patterns in North Fishtail Bay that was conducted from June through August, 1972 and 1973.
