Cass River Rock Dam

Located in the heart of Frankenmuth, at the Cass River Dam, Frankenmuth’s Fish Passage project reconnects the fish of the Saginaw Bay to more than 73 miles of historically significant spawning areas. While the focus of the project is on fish passage, the project maximizes opportunities to benefit Frankenmuth’s local economy – keeping the river profile as it is today and adding opportunities for recreation that sustain the tourism industry and employment center through eco-tourism. Regionally, the project benefits the Saginaw Bay Watershed, supporting local and regional efforts to improve the premier water resource, creating a desirable recreation center, and a successful and sustainable tourism destination.
