CARSON, Iowa -- On April 15, 2019, at approximately 6:00 pm, the Iowa DNR Field Office 4 staff was notified about a potential discharge occurring at Cyclone Cattle Open Cattle Feedlot in Carson, Iowa.

Upon investigation, DNR staff made contact with the owner of Cyclone Cattle and he said he was land applying manure-laden water from an on-site settled open feedlot effluent basins (SOFEBs) to an adjacent property.  During the land application efforts, the manure-laden water from the pivot flowed through a grassed waterway in the application field and flowed into an unnamed tributary of the West Nishnabotna River.

A fish kill was not observed and water samples were collected for analysis. The center pivot was turned off at approximately 8:30 pm. The cause of discharge into the tributary remains under investigation, but is believed to be a mechanical issue, and appropriate enforcement will be considered.
