The Sandusky River (Wyandot: saandusti; Shawnee: Potakihiipi [1]) is a tributary to Lake Erie in north-central Ohio in the United States.
It is about 133 miles (214 km) long[2] and flows into Lake Erie at the southwest side of Sandusky Bay.
The Ballville Dam, built on the Sandusky River in Fremont, Ohio, blocked migration for walleye and other fish.
As fish can swim farther upstream in the Maumee, they have access to more spawning areas and have developed a larger population than in the Sandusky River.
The Sandusky River begins at the juncture of Paramour Creek and Allen Run at the unincorporated community of Leesville in Crawford County west of Crestline,[6] and initially flows westwardly, passing through the town of Bucyrus.
