FISH KILL IS COMMON DURING THE SPRING THAW

2/26/2021

As the season changes from Winter to Spring it can be common for fish kills to happen.  Winter kill is the most common type of fish kill.  Lakes with excessive aquatic vegetation and soft bottoms are prone to experiencing this problem as deep snow on the ice surface reduces sunlight for the plants.  Stress from rapid changes in water temperature due to unseasonable warm/cold temperatures can also be a factor in fish kill.

Fish kill may not be noticed until a month after the ice has thawed as the dead fish are temporarily preserved by the cold water temperatures.  This could very well be the case this year with the near record cold temperatures and large snowfalls we have experienced.
