Frankenmuth Dam Fish Passage

Construction sign about the Frankenmuth Fish Passage ProjectThe 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 existing Frankenmuth Dam effectively prevents the upstream passage of fish and separates Saginaw Bay fish from valuable spawning habitat. The project includes 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 will open up 1,763 miles of reproductive territory to the walleye.
