Boaters heading to the launch on Clear Lake in Waseca have been wondering why there are hundreds of dead fish, and FOX 9 News found out that the sudden warm weather is causing an early fish kill that usually wouldn't be seen until late June or July.
Josh Lyman's fishing boat has been sitting idle in his Owatonna driveway ever since he came across dozens of dead fish at the launch.
"There's a bunch of dead fish -- small fish and big fish, just an awful smell," he said.
Lyman planned to go fishing on Saturday, but opted against once he saw all the dead fish and didn't know why so many had died.
"First thing we thought was, 'Some sort of problem with the fish,'" Lyman said.
On Sunday, FOX 9 News found Steve Cox fishing on the water, and he had no idea that so many fish had died until he came over to see why the cameras were rolling. Even though the Department of Natural Resources says it's still perfectly safe to eat any fish you catch from those waters, he admits the find put him off his appetite.
"It makes me not want to eat them," Cox admitted.
The DNR believes the unseasonably warm weather in the past few days is likely the culprit in the fish kill because it's sometimes hard for fish to acclimate to quick changes in water temperature.
