Fall Creek flows through both Cayuga and Tompkins Counties in New York before emptying into the south end of Cayuga Lake. This tributary supports populations of brown trout, rainbow trout, brook trout, and Atlantic salmon, making it a destination for anglers targeting migratory fish from Cayuga Lake. The creek varies from small intimate water in its upper sections to larger, deeper runs as it approaches the lake. Fall Creek receives annual stockings of brown trout, with approximately 2,520 fish stocked each spring in the Groton area, including both 9-10 inch and 12-15 inch specimens. The fishery offers both resident trout fishing and seasonal runs of lake-run fish that enter the system during specific times of the year.
