Fish Kill on Lake Francis Case

Quote:

Officials are trying to determine the reason for a fish kill on Lake Francis Case south of Chamberlain, SD.

The Game, Fish and Parks Department said hundreds of dead carp, catfish and paddlefish were found from the mouth of the White River downstream several miles to the Elm Creek area. The GF&P and the state Department of Environment and Natural Resources are investigating.

Fish kills can occur naturally because of high water temperature, low oxygen levels or bacterial and viral infections. They also can be caused by toxic substances entering the water from human activity, such as industrial or agricultural runoff.
