General lake Ice information

  • General ice thickness guidelines
    • For new, clear ice only
    • UNDER 4" - STAY OFF
    • 4" - Ice fishing or other activities on foot
    • 5" - 7" - Snowmobile or ATV
    • 8" - 12" - Car or small pickup
    • 12" - 15" - Medium truck

Many factors other than thickness can cause ice to be unsafe.

White ice or "snow ice" is only about half as strong as new clear ice. Double the above thickness guidelines when traveling on white ice.
