Consumers Energy’s Gamble With Michigan’s Largest Dam: Delaying a Critical $350 Million Safety Fix While Lives Hang in the Balance
Hardy Dam on the Muskegon River is Michigan’s largest hydroelectric dam. It is also a high-hazard structure whose failure would put thousands of people and hundreds of millions of dollars in property at risk downstream, stretching into Muskegon County. After federal regulators updated flood estimates, Hardy no longer meets the standard requiring high-hazard hydropower dams to safely pass the probable maximum flood—the largest flood scientists consider physically possible at the site. The existing auxiliary spillway is undersized. A major storm could overwhelm it.
