DNR expects hot weather to cause fish kills in northwestern Wisconsin

Warmer weather could lead to fish kills in northwestern Wisconsin in the coming weeks.

Department of Natural Resources biologists say the Columnaris bacteria becomes active and starts impacting the fish population when water temperatures top 65 to 70 degrees.

That bacteria doesn't hurt human beings, but it can kill fish. It erodes their skin, causes bodily fluids to leak and results in death pretty quickly.

Bluegill, bullheads, crappies and yellow perch are affected the most.

State wildlife officials warn of the potential for fish kills in Polk, Barron, Washburn and Burnett counties.

Though we could see a lot of dead fish, the overall fish population won't be affected dramatically.
