The U.S. Army Corps of Engineers may take another look at placing structures in the St. Clair River to boost water levels in Lakes Huron and Michigan.

The river is at the southern end of Lake Huron and has been dredged over the years to deepen the navigational channel. That allowed more water to flow out of the two lakes, which are connected.

The lakes are now at their lowest levels since record-keeping began in 1918.

Keith Kompoltowicz (Kom-POL-toe-witz) is watershed hydrology chief with the Army corps district office in Detroit. He says Congress authorized the corps long ago to put structures in the river to slow the outflow, but nothing happened. He says the corps may ask Congress for money to study whether such action should be taken.
