DNR warns slush weighs down ice

This month’s snowstorm that dropped heavy, wet snow across much of the state has significantly affected ice conditions, according to the Minnesota Department of Natural Resources.

Slush adds weight to the ice and its effects can be unpredictable. In some areas, slushy conditions are impacting travel on the ice, while in others — especially where ice was in the early stages of forming — the conditions are not adequate to support ice shelters and vehicles, resulting in breakthroughs.

When on the ice, people should check the thickness for themselves and not rely on tracks in the snow or what they’ve heard secondhand. When measuring the thickness of slush-covered ice, measure only the clear ice, not the slush or snow on top of it. While forecasted cold weather could help strengthen ice, it’s vital to check ice thickness regularly. The DNR recommends at least 5 to 7 inches of ice for snowmobiles, 7 to 8 inches for side-by-side all-terrain vehicles, and at least 20 inches for heavy-duty trucks pulling wheelhouses.

“There are many tools to help you determine whether the ice is safe — augers, drills, spud bars and tape measures — but the calendar isn’t one of them,” said Col. Rodmen Smith, director of the DNR Enforcement Division.
