Sanford Lake is a man-made reservoir located in Midland County, Michigan. It was formed by the damming of the Tittabawassee River near the town of Sanford, Michigan. The dam is owned and operated by Boyce Hydro,LLC. The main body of the lake stretches for about 6 miles (9.7 km) north of the dam, but the water remains deep enough for small boat navigation up past the town of Edenville, Michigan ten miles (16 km) north of the dam.
