Onsite Comments

The loss of fish occurred as a result of a discharge of cattle manure from an open feed lot. Received a call this afternoon of dead fish in the Willow Creek at a bridge located at 450th Street and 180th Avenue in Clay County. I investigated and found approx 400 dead minnows, 25 dead bullheads, and 1 dead northern pike. The other fish were stressed and swimming towards to surface. Pictures were taken. Field test kit showed no D.O., ammonia of 12.5 mg/l, and water temp of 12 C at the bridge located at 450th Street and 180th Avenue.
