A manure spill and small fish kill in Jasper County south of Laurel is being investigated by the Iowa Department of Natural Resources.
The DNR was alerted late Wednesday morning by a farmer who spotted dead small fish and crawdads as well as a manure odor coming from a tributary of Alloway Creek south of Laurel. Environmental specialists found some smaller dead fish and crawdads that looked to have already begun decomposing.
After detecting slightly higher than normal ammonia levels in the water, environmental specialists for the DNR were able to track the manure spill back to a 4000-head hog facility owned by Clinton Vos of Newton. It was determined that manure was leaking from a sidewall of the hog confinement and pooling outside of the building.
Although manure was not going into the creek when the environmental specialists arrived, it was apparent that manure had run to the creek through a soybean field during a recent rainfall event.
By late afternoon, the owner had repaired the hole in the side of the building and had constructed a berm to contain the manure that was pooled.
