FONDA, Iowa (AP) — Officials are investigating a fish kill on Big Cedar Creek in northwest Iowa.
The state Department of Natural Resources says officials in Pocahontas County reported Monday that they discovered brown water that smelled like manure. They also found dead carp and minnows in the stream.
DNR officials found high levels of ammonia and traced it to an underground tile line. They followed the tile line to a small hog confinement nursery in rural Varina.
Officials are investigating the incident, and a fish kill county is being conducted.
Big Cedar Creek is located about seven miles northeast of Fonda.
