The Carpentersville Dam on the Fox River is slated for removal in 2022, a move that state and local officials say will have a big effect on the river’s biodiversity and safety.

According to the IDNR, 34 dams have been removed or altered on the Fox, Des Plaines, Kankakee, Chicago and DuPage rivers and their tributaries since 2003. Seven new removal/remodification projects are in the works, including the one in Carpentersville, and are to be completed between 2020 and 2022,officials said.
