Flint Creek is a creek located between Canandaigua and Seneca Lake that runs from the Potter area to Phelps. Flint Creek is part of the Canandaigua Lake watershed which is part of the Oswego River drainage basin, which drains into Lake Ontario. Flint Creek flows through the hamlets of Potter, Gorham, and Seneca Castle, and ends in the village of Phelps.
A part of Flint Creek known as Phelps Run is used for whitewater rafting and kayaking and has class II, III, and IV rapids. The run is only three miles and has an average gradient of 50 feet per mile.
A very large area of muckland used for vegetable crop farming was created by clearing and draining a swamp along Flint Creek located in the Town of Potter. Flint Creek flows through the middle of the area and is used for irrigation. Known as The Muck, a large portion is run by Torrey Farms of Elba.
