Winter transforms Lake Kohlmier into a playground for ice fishing, skating, and snowmobiling. Yet, embracing these joys requires us to prioritize safety due to the unpredictable nature of the lake's ice cover. The Minnesota Department of Natural Resources (MN DNR) highlights that ice strength varies, and we shouldn't trust its safety by looks alone. Factors influencing strength include temperature shifts, lake size, and underwater currents. Ice that's new and clear is generally stronger—MN DNR advises a thickness of at least four inches for individuals.

Snow on the ice can be deceptive; it insulates and adds weight, making the surface less stable. It's critical to measure the ice's thickness every 150 feet while enjoying outdoor activities. The recommended guidelines provided by the MN DNR for various activities are as follows:

  • 4” for ice fishing or on foot
  • 5”-7” for snowmobile or ATV
  • 8”-12” for cars or small pickups
  • 12”-15” for medium trucks Remember, for white ice or snow-covered ice, these guidelines should be doubled. By following these parameters and staying informed about Lake Kohlmier's conditions, we can ensure a safe and enjoyable winter season.
