DNR watching water levels at the Cheboygan Dam
April 07, 2026
Michigan Department of Natural Resources Parks and Recreation Division officials are closely monitoring water levels in the Mullett Lake Watershed after recent weather events, including rain, snow and melting.
“We are experiencing very high water levels. All the dam gates are open, and we are passing as much water through the dam gates as we can,” said Rich Hill, DNR Gaylord District supervisor.
The DNR is working with local officials to manage the situation. A comprehensive plan is in place to help keep the public safe should high water conditions persist.
The outflow from Mullett Lake and the Black River feed the Cheboygan River behind the Cheboygan Dam, before the river flows through the town of Cheboygan and north to its mouth at Lake Huron.
The DNR has been checking water levels at Mullett Lake, along the Cheboygan River and at the dam over several days. The water level at the dam today measured 21.5 inches below the top of the dam.
Normal spring runoff, a significant recent snowstorm and rains have all contributed to the high water. Rain or snow are forecasted for the area tomorrow.
The Cheboygan Lock and Dam Complex is comprised of the Cheboygan Lock and Dam, as well as a privately owned hydroelectric facility. The complex is regulated by the Federal Energy Regulatory Commission.
The watershed covers approximately 1,455 square miles.
