A Preston-area cattle producer has to pay a $10,000 penalty after digging a trench to send manure down a ditch and into Copper Creek.
James Carstensen also agreed to stop manure discharges or get a permit for them in the future, according to an order filed with the Iowa Department of Natural Resources.
The James Carstensen feedlot at 45436 45th St., Preston, is about a third of the mile from Copper Creek and is north of Highway 64 between Preston and Miles. It has two settling basins with a capacity for 700 head of cattle.
On May 24, the Iowa Department of Natural Resources learned that Carstensen had dug a trench to a ditch that feeds into the creek. A DNR field officer could see manure in the creek.
