Investigators with the Iowa Department of Natural Resources say they are still unable to determine the source of Monday’s fish kill in Carroll County. The dead fish were discovered in Elk Run Creek, four-miles Northwest of Lidderdale, as officials with the D-N-R were checking on a complaint about a dead cow. Investigators were initially unable to estimate the number of fish killed, because heavy rains earlier in the week muddied the waters. They were eventually able to determine more than 13-hundred minnows, 91-stonerollers and 10-suckers were lost. According to the D-N-R’s Alison Manz, investigators believe runoff from an open feedlot is the cause of the kill, but the exact location is still a mystery. To help track the source, they began dye testing the water, Wednesday. Manz says anyone seeing red dye should give the D-N-R a call, but you should not become alarmed. Water from the creek flows into the North Raccoon River, and officials downstream in Des Moines are aware of the problem.
