The Iowa Department of Natural Resources has been investigating a fish kill in Poweshiek County.  The fish kill was reported September 11 at Little Bear Creek, a mile west of Malcom.  DNR investigators found high ammonia levels in storm water runoff from Fremont Farms northwest of Malcom…and a second source of storm water runoff was found at the nearby Jerry Axmear farm.  It turns out the manure storage at the egg-laying facility was too full…and that caused a leak in one of the buildings.  So the manure was exposed to rainfall and while the manure was blocked at the farm, the high ammonia levels flowed into the creek.  DNR staff found dead fish for about three miles along the creek bank.  Work is underway at both Fremont Farms and the Axmear farm to prevent more runoff from reaching the creek.
