Last winter’s heavy snowfall is partly to blame for a fish kill that took out tens of thousands of walleye, bass, northern pike and other species on Grand Lake near Duluth. Dan Wilfond, Department of Natural Resources fisheries specialist for the Duluth area, said even bullhead were among the species affected — an indicator that the fish kill was fairly severe. He estimates roughly 35,000 fish died.
Minnesota officials on Monday were trying to determine what killed thousands of fish in Lake Owasso. There’s no evidence of a chemical spill or toxins, and tests show that oxygen levels are normal, said Harland Hiemstra, a spokesman for the Minnesota Department of Natural Resources. Lake Owasso lies within Shoreview and Roseville in the northern St. Paul suburbs. The lake is managed primarily for muskies, he said. Lake resident Les Hassler said he’s counted thousands of dead fish since it froze over last Tuesday. Hundreds of fish could be seen belly-up inches beneath the new ice on Sunday.
It’s a smell that comes with warmer temperatures and increased algae in the water. It’s also something you can see: dead fish floating on all the lakes in Minnesota. The experts call it a “fish kill,” and it has many wondering is the water safe. Dawn Summers of Minneapolis Park and Recreation says that this is a common occurrence.
The spring weather brought with it something pretty unsightly near St. Paul. Hundreds of fish recently died in Beaver Lake, and many of them ended up all along the shoreline.
The Minnesota Department of Natural Resources says high temperatures may be contributing to fish kills in lakes around the state.
The recent heat wave is blamed for killing thousands of fish in several southern Minnesota lakes. Most of the lakes are shallow, and thus more susceptible to summer fish kills, and most of the fish were northern pike, which prefer cold water.
They’re what Minnesota fishermen want to catch, so seeing hundreds of dead Northerns and Walleyes isn’t sitting well with many.
The Minnesota Department of Natural Resources (DNR) said a virus is to blame for the killing of 200-300 Minnehaha Creek carp in June.
