DNR investigates Lake Zumbro fish kill
The Minnesota Department of Natural Resources is trying to find out what killed hundreds of channel catfish in Lake Zumbro near Oronoco.
Area fisheries supervisor Kevin Stauffer says the DNR received several calls Monday about dead catfish. But only one catfish was found in good enough condition Tuesday to be tested.
The DNR estimates it found about 500 dead fish along the shore, but Stauffer says many more could have sunk, gone over the dam or been eaten by predators.
He says while it's a lot of fish, "this probably is not a huge percentage of the population" because the southeastern Minnesota ake is known for its channel catfish.
