Crews will begin lowering a spillway connected to a dam that failed last year and contributed to massive flooding in parts of mid-Michigan.

The Edenville Dam Tobacco River spillway will be lowered by more than 20 feet (6 meters) starting Feb. 24 to help prevent future flooding, according to Michigan’s Department of Environment, Great Lakes, and Energy.

Water levels are expected to drop about 12 feet (3.6 meters) behind the dam — and less upstream — by the second week in March, the agency said Wednesday.

A group responsible for offering new safety measures after two Michigan dams failed last summer destroying 150 houses and causing over $200 million damage delayed sending the governor its final recommendations, which include increased monitoring of dams and other risk reduction measures.

The Michigan Dam Safety Task Force has been working on recommendations that would require Legislature approval to reduce the threat of dam failures after two dams failed in Midland County last May, forcing the evacuation of 10,000 people.

Crews have started emergency construction work on a portion of a central Michigan dam that collapsed last spring and contributed to flooding that destroyed homes and forced the evacuations of about 10,000 people.

Excavation work will be done below the Edenville Dam in Midland County, according to state officials.

The dam failed during a steady rain in May, draining Wixom Lake and unleashing the Tittabawassee River, which then overwhelmed the Sanford dam, about 140 miles north of Detroit.
