Clinton, IA – While doing a follow-up check on manure application just north of Clinton on September 12, an official with the Iowa Department of Natural Resources found manure in a tributary of Silver Creek flowing into Silver Creek and about three miles to the Mississippi River.

The manure came from an overflowing storage basin at a nearby dairy operation. The dairy has hired a manure applicator to land apply manure. The basin has stopped overflowing.

A DNR inspector found the basin had been overflowing for some time. An unknown amount of manure reached the creeks. There were no signs of a fish kill in the creeks.

Recent heavy rains have affected some manure storage structures in the state. However, the DNR recommends that livestock producers contact the local DNR field office for help when faced with issues because of rainfall. Exploring alternatives for manure application and storage before it’s a problem is better than dealing with a manure release.

The DNR will continue to monitor the situation and cleanup, and will consider appropriate enforcement action.
