Frankenmuth Dam Fish Passage
The Frankenmuth Dam is located on the Cass River in the City of Frankenmuth, Mich., approximately 20 miles south of Lake Huron’s Saginaw Bay. The previously existing Frankenmuth Dam effectively prevented the upstream passage of fish and separates Saginaw Bay fish from valuable spawning habitat. This project included construction of a rock ramp structure to provide an approximate 3% grade up to the dam, allowing passage of the target species upstream. Providing fish passage at the Frankenmuth Dam opened up 1,763 miles of reproductive territory to the walleye.
