Officials with the Iowa DNR said Tuesday, that they had received an anonymous complaint of an overflowing manure pit in Taylor County. When the DNR investigated, they found evidence of a manure spill at Barrans Farms, a small hog finishing farm about three miles southwest of Lenox. The outdoor pit that collects manure from buildings at the site was not overflowing during the investigation.

However, DNR field staff saw a path where manure flowed into an unnamed tributary of the East Fork of the One Hundred and Two River. Field tests showed elevated levels of ammonia in water flowing into the tributary, but DNR staff did not find any dead fish. The DNR is continuing to investigate the incident and will consider appropriate enforcement action.
