The DNR is investigating three manure discharges caused by the recent heavy rainfall in northwestern Iowa.
ROCK RAPIDS, Iowa -- The DNR responded to Gaylon Rozeboom Feedlot where the effluent basin is overflowing and reaching a nearby unnamed tributary of Mud Creek, which is out of its banks due to the excessive rainfall. The owner has been land applying manure, but the ground is saturated from the rain and the applied manure is running off into the same flooded unnamed tributary in a different location. Water samples have been collected by the DNR. In the meantime, the owner will turn the pumps on and off more frequently to minimize the discharge.
ROCK VALLEY, Iowa – The DNR responded to Remmerde Farms’ where the effluent basin is overflowing and reached an unnamed tributary of Dry Creek. The owner will pump as often as possible to try to eliminate the discharge.
ROCK VALLEY, Iowa -- DNR staff observed a discharge at Van Essen Feedlot in Rock Valley. The manure discharge is coming from a leaking pipe near the effluent basin. DNR staff is working with the owner to determine the cause of the discharge and to get it stopped. The manure discharge was entering an unnamed tributary of Dry Creek.
All facilities are covered by NPDES discharge permits; however, the DNR will consider enforcement action if appropriate.
No fish kills were reported or observed from these discharges.
