A winter fish kill in Wisconsin’s Silver Lake, likely due to ice blocking oxygen, prompts DNR investigation and a spring recovery survey.
A fish kill in Silver Lake, Manitowoc County, Wisconsin, has led the DNR to investigate low oxygen levels, particularly in the southwest corner, where underwater cameras found 5–10 dead panfish per site.
No pollution or runoff was detected, and the event is likely linked to winter fish kill patterns from ice cover limiting oxygen exchange.
The DNR ruled out contamination and plans a spring survey after ice melts to assess recovery, with full population restoration expected in up to seven years.
