Officials say a dam has failed on a man-made lake in Roscommon County, forcing closure of part of a two-lane highway called Old 27.
Rex Ainslie of the Michigan Department of Natural Resources says the agency owned the earthen dam that held back a shallow lake on Wolf Creek, a tributary of the Muskegon River.
Flooding from heavy rains and melting snow continues to threaten homes and disrupt traffic in many areas of Michigan.
The National Weather Service reports that the Muskegon River has risen to a record level in Osceola County, cresting at 15.55 feet and surpassing a record of 15 feet set in 1989.
The river has risen above major flood stage near Croton Dam in Newaygo County.
Authorities are asking people living below the dam to evacuate.
