​​​​​​​​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.
