We encourage our Michigan neighbors to be very careful when visiting areas near our 13 hydroelectric generating plants located on the Manistee, Muskegon, Au Sable, Kalamazoo and Grand Rivers.
In particular, watch for thin ice upstream and downstream of the dams. Ice conditions on the reservoirs next to these hydro plants can change rapidly due to unpredictable weather.
Water currents at a hydroelectric plant can be hazardous in winter, when a reservoir may or may not be covered with ice. Ice near a dam is not reliable and should be avoided by snowmobilers, anglers and anyone else.
Ice-covered water downriver from a hydroelectric facility should also be considered very dangerous, and is never a safe place to walk.
Built between 1906 and 1935, our hydros are an important contributor to renewable energy in Michigan and have a combined generating capacity of approximately 130 megawatts, which is enough to serve about 70,000 people.
