The Iowa Department of Natural Resources says several hundred thousand gallons of manure was spilled in a northwest Iowa creek, resulting in a fish kill. According to a news release, the spill occurred near Mud Creek, northwest of Rock Rapids in Lyon County. DNR staff said Bernie Baker of Rock Bottom Dairy reported the spill Wednesday. The liquid manure flowed across fields, including some with cover crops or pasture, before reaching Mud Creek. Officials with the DNR said in the release that livestock producers who depend on the creek as a water source should check stream conditions for the next few days. DNR staff was monitoring the cleanup and assessing the extent of the fish kill. The DNR will consider appropriate enforcement, the release stated. The spill was one of two reported on Wednesday. Officials with the DNR said a manure spill occurred about 2 miles north of West Bend in Kossuth County, where Precision Pumping, a commercial manure application company, spilled 10,000 gallons of manure into a creek when a hose came off a pump. A large number of dead or dying fish were found in Lotts Creek, which flowed into the East Fork of the Des Moines River. Appropriate enforcement was being considered.
