Granville, Iowa — DNR staff are investigating a manure release from a dairy barn about three miles south of Granville in Sioux County.
According to the Iowa Department of Natural Resources, about 8 a.m. Monday, owner Nate Zuiderveen saw a manure discharge flowing from the barn into an underground tile line. Manure had backed up in the barn after a pump plugged. Zuiderveen immediately stopped the pump, ending the flow.
The DNR says it’s unknown how much manure reached a tributary of Deep Creek, but Zuiderveen reportedly said he saw manure two miles downstream.
DNR staff will look downstream for environmental impacts and determine the extent of the manure flow.
The DNR says they will monitor clean up and consider appropriate enforcement action.
