DNR Investigates Fish Kill in Sioux County
Posted: 11/01/2012
SIOUX CENTER – The DNR has traced a fish kill in the West Branch of the Floyd River south of Sioux Center to a local business.

Pending lab results, it appears the likely source of the discharge causing the fish kill is Sioux-Preme Packing Company. The company is located just south of Sioux Center at 4241 U.S. 75 Avenue. The DNR continues to investigate the reason for the discharge.

DNR staff found elevated ammonia levels and thousands of dead fish, including game fish, for at least nine miles downstream of the plant. Fisheries staff conducted a second count of dead fish after fish continued to die on Tuesday and Wednesday, and are back on the site today.

Sioux-Preme Packing Company has hired a contractor to pump and land apply water pooled in a tributary to the stream where ammonia has concentrated. The DNR will continue to monitor cleanup.

The agency will pursue appropriate enforcement action and fish restitution.

The fish kill was reported to the DNR on Monday after a resident noticed stressed fish in the stream over the Oct. 27 weekend.

It’s important to call the DNR’s 24-hour spill line at 515-281-8694 as soon as possible after seeing a fish kill. The greater the delay between the event and the reporting, the less likely it is that the source of the pollution can be traced.
