The Iowa DNR says summer heat has led to a fish kill in northeast Iowa.
Theresa Shay, fisheries technician with the DNR, says dead fish in the unnamed tributary to Otter Creek that flows through Oelwein is the result of a natural kill caused by extremely warm water temperatures and low flow conditions on the stream.â€
Just over two miles of stream was affected by the warm water and less than 1,000 fish were killed. Species primarily affected include smaller minnows, dace and suckers. Â
Shay said investigators saw live fish of multiple species in the same locations that appeared in good condition.Â
