Thin Ice Warnings

The Minnesota Department of Natural Resources is reminding snowmobilers and others to stay off lakes because the ice is not safe yet.

According to the DNR, there have already been several ice rescues involving snowmobiles. There have been several drownings involving those venturing out on ice.

“We’re telling snowmobilers and others to please stay off of lakes until there is at least five inches of new, clear ice,” said Lt. Dave Olsen, DNR Enforcement, Grand Rapids “Early season riders are often tempted to ride on lakes. But they are not yet safe for snowmobiles, ATVs, or even walking, in most cases.”

The DNR is also warning ice anglers, snowmobilers, skiers and other outdoor enthusiasts to use caution when going onto any lake covered or partially covered with ice, especially those that feature aeration systems.
 
Aeration systems are generally operated from the time lakes freeze until ice break-up in the spring. They help prevent winterkill of fish, but they also create areas of open water and thin ice, which are significant hazards.
 
Two types of signs are used to post aerated lakes; “Thin Ice” and Warning” signs.
 
Area lakes which are aerated include Platte in Crow Wing County, and Alexander and Shamineau in Morrison County.
