Dam removal improves river, saves community festival

Project Summary: The failure of a dam in northern Michigan led to a solution that restored fish passage in an important Lake Huron tributary and saved a popular community festival in the process.

 

Project name: Chesaning Dam removal.

Location: Chesaning, Mi.

Description: The Chesaning Dam was built in 1863 to power a grist millage in the village of Chesaning, located about 40 miles northwest of Detroit. The dam on the Shiawassee River was a community fixture and the pond it created was the site of the popular Chesaning Showboat Festival, an annual event that began in 1837. The partial collapse of the dam in 2005 created a safety hazard, lowered water levels in the impoundment and jeopardized the Showboat Festival. Faced with the prospect of losing the dam and the festival, community leaders and state officials worked with engineers to develop a unique solution that restored natural conditions in the river while maintaining water levels that were sufficient to support the Showboat Festival. The dam was removed and replaced with manmade rapids that were comprised of a series of rock ramps and boulder arch weirs in the river. The step-down structure restored fish passage, giving walleye and sturgeon in the Saginaw River and Lake Huron access to 37 miles of the Shiawassee River above the former dam, and preserved water levels upstream that were sufficient to support the Showboat Festival. The manmade weirs also created whitewater rapids that attracted kayakers and became a new point of pride for the community.

Approximate cost of project: $1,410,400, which was provided by the state of Michigan’s Clean Michigan Initiative, the U.S. Fish and Wildlife Service and several local organizations.

Resource challenges addressed: Degraded fish habit and the loss of ecological connectivity between 37 miles of the Shiawassee River and Lake Huron.

Key partners (public and private): Village of Chesaning and Chesaning Township, Saginaw County, Wade Trim, Ellen River Partners, Saginaw Bay Watershed Initiative Network, Friends of the Shiawassee River, the Saginaw Community Foundation, Michigan Department of Natural Resources, Michigan Department of Environmental Quality, U.S. Fish and Wildlife Service and the U.S. Army Corps of Engineers.

Types of jobs created: Civil engineers, biologists, ecologists, heavy equipment operators and general laborers.

Results and accomplishments: The project gave walleye and lake sturgeon in the Saginaw River and Lake Huron access to 37 miles of spawning habitat in the Shiawassee River and saved the popular Chesaning Showboat Festival.
