The state is warning people to avoid an area downstream of the Corunna Dam on the Shiawassee River in mid-Michigan, saying the structure is at risk of failing.

The state Department of Environmental Quality announced Monday that it planned an emergency drawdown of water behind the dam, located east of Owosso and about 30 miles northeast of Lansing. The department says inspections in recent months determined the structure could fail suddenly.

Repairs are planned.

The department says there's a breach in the dam's spillway. The DEQ says that could lead to a sudden failure that would release water and sediment downriver.

The emergency drawdown of water behind the dam was expected to start Monday. A full drawdown of the water behind the dam is expected by August 12.
