Sign up for local alerts to keep up with the latest news and information

With Michigan Department of Natural Resources officials continuing to monitor spring runoff on the Cheboygan River today, the water level at the Cheboygan Dam and Lock Complex rose slightly overnight.

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 inches below the top of the dam, which represents a half-inch increase since Tuesday.

“We are watching the water level 24 hours a day, with the dam gates fully open,” said Rich Hill, DNR Gaylord District supervisor. “We are working closely with local, state and federal officials to keep abreast of any changing conditions.”

Spring runoff, a significant recent snowstorm and rains have all contributed to the current highwater conditions. Weather forecasted for the area includes rain or snow for today with sunnier skies expected Thursday.

A comprehensive plan is in place to help keep the public safe should water levels at the dam and lock increase significantly. People in the region are urged to sign-up for local alerts to keep up with the latest news and information.

If the water level reaches 12 inches before topping the dam, the county’s Emergency Action Plan will be activated, which initiates additional actions to notify local emergency, fire and police departments.

The plan is necessary to organize, coordinate and direct actions of the DNR, officials, city/county emergency services and the public to execute prepared plans of operation and to maintain the continuity of government.

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 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.
