Hawarden, Iowa — According to the Iowa Department of Natural Resouces, their staff investigated a complaint of a manure spill northeast of Hawarden on Wednesday.
They tell us they traced the spill to a broken manure application hose which they say released an unknown but significant amount of manure early Wednesday morning. The manure flowed into an underground tile line, then into an unnamed stream moving several miles before entering Six Mile Creek, a tributary of the Big Sioux River.
DNR officials say manure from the Van Voorst Dairy in Sioux Center was being land applied by Pro Pumping of Mitchell, South Dakota, when the hose broke. The applicator shut down the pumps after discovering the break.
DNR staff did not see any fish in the stream.
The DNR says they will monitor the cleanup and consider appropriate enforcement action.
