Be Cautious - Thin ice - Practice Ice Safety

  • Factors that Affect Ice Thickness

    • Sudden drops in temperature weaken ice
    • Slushy snow or water on top of ice may hide cracks in it
    • Snow cover over ice may warm the ice up sufficiently to weaken it - even on a cold day
    • Wildlife may contribute to weakening of ice
    • Any objects (logs, rocks) sticking out from the ice weaken it
    • Warm weather, especially springtime, makes ice unpredictable as the ice thaws
      • Stormwater lakes and ponds can be warmer, more turbulent and melt ice faster than natural bodies of water
      • Salt flowing into the ponds and lakes from roads can also help to speed up ice melt
      • Constantly flowing water means water will not freeze; most stormwater lakes and ponds will not freeze through to the bottom
      • Most stormwater ponds are connected, with as many as 10 or 12 in a row, exacerbating melting conditions downstream
      • Stormwater lakes and ponds retain groundwater year round. As a result, the water underneath the surface is constantly moving, which means it does not freeze as evenly as natural bodies of water. Therefore, it is not safe to use stormwater lakes or ponds for recreational purposes
