Dams and Hydros

The water treatment services unit operates and maintains four dams located on the Huron River: Barton, Argo, Geddes, and Superior. Two of the dams (Barton and Superior) generate hydroelectric power.  At peak power production these two dams can create enough electricity to power 1500 homes. All four dams are operated to maintain pond levels. Each of the dams has an automatic controller designed to maintain the pond level within a 0.1 foot range.​

Barton Dam Embankment Remediation Project: Feb. 25, 2025-June 2027

The Barton Dam embankment construction work is now underway, as of Feb. 25, 2025. The dam is adjacent to Barton Pond, Barton Nature Area, Bird Hills Nature Area and trails to and along the Huron River. Public access is now restricted in designated areas. When visiting this area, please note the posted safety restrictions, barricades and signage on site and use caution in areas that remain open, such as the parking lot, pathway and other areas west of the Huron River, as some of these open areas will be shared by construction operations and construction traffic. Thank you for your patience. This project is required for Federal Energy Regulatory Commission (FERC) compliance and will include stabilizing a berm on the downstream slope of the right embankment to address seepage and stability concerns. The anticipated completion date is June 2027. For details, please see:  Jan. 22, 2025, news release​  | Feb. 26, 2025, news release |  Map of restricted areas (PDF)​
