The Menomonee River Ecosystem Restoration Project began in September 2014 in an effort to restore fish passages and access to historic spawning habitats. The project consisted of removing 2,900 feet of concrete that had lined the channel along the Menomonee River since the 1960's. Once removed, a natural riverbed was placed. This natural riverbed has opened access to over 37 miles and 125 acres of high value, upstream, shallow wetlands that various fish species use for spawning. The project also provides connectivity between previously restored sections of the Menomonee River, while reducing the risk of flooding. A recreational sport fishery, has also been restored through this project, which extends along 17 miles of river and 20 miles of tributary in one of Wisconsin’s most populated and diverse watersheds.
