Consumers preparing to cut flow to Manistee River for dam inspection
Consumers Energy plans to temporarily reduce water flow in the Manistee River for dam inspections starting Sept. 21. The company says this is necessary to assess storm damage safely, but river advocates oppose the plan and question alternatives. The inspection may lower water levels by about a foot, with measures in place to protect wildlife. The company is also considering selling its dams to a private equity firm for $1 each, a deal facing regulatory opposition.
