The Iowa Department of Natural Resources (DNR) is considering enforcement actions against a Crawford County farmer for allegedly dumping hundreds of gallons of milk that found its way into a nearby waterway. County officials notified DNR staff late Wednesday afternoon of cloudy water in Willow Creek about four miles southwest of Denison. An investigation determined Harold Chapman, a dairy farmer, had released an estimated 400 gallons of milk after he discovered a cooler had failed. The milk flowed for about a quarter mile before entering the creek near the intersection of 220th Street and Q Avenue. State officials say spills like this are dangerous to aquatic species because bacteria in the stream breaks down the organic products, drastically reducing the water’s oxygen levels. The DNR says stream flows were high and they did not locate any dead fish. However, samples were collected from the site for additional analysis.
