COLDWATER, Mich. (AP) — Officials in southern Michigan say the Coldwater River’s Blackhawk Dam is failing, which may lead to flooding if the crews aren’t able to adequately repair the structure.

The Kalamazoo Gazette reported Sunday that local officials were dispatching repair materials and equipment in hopes of repairing the dam.

But Branch County Emergency Management Coordinator Tim Miner warned that the effort may not be able to stop “significant” flooding in the area.

Officials announced that the dam was failing in a statement released around noon Sunday.
