(Ramsey County, MN) -- The Minnesota Department of Natural Resources is blaming too much oxygen in the water at Lake Owasso with killing off hundreds of fish last week. The "Star Tribune" reports bass, walleyes, muskies and crappies have been dying off, with a DNR specialist calling it a "freaky thing." Fisheries specialist Donn Schrader added most often, fish are killed in lakes over the winter due to a lack of oxygen. DNR officials don't know what caused the spike in oxygen levels, but believe the event is over.
