GUTHRIE CENTER, Iowa (AP) - Environmental specialists with the Iowa Department of Natural Resources are investigating following the crash of ammonia tanks into a western Iowa creek.
The department says dead fish were discovered downstream from where two anhydrous ammonia tanks and a tractor fell into Brushy Creek north of Guthrie Center on Friday.
The tractor was pulling a disc and the two tanks when an old wooden bridge it was crossing collapsed and the equipment fell into the creek. Investigators determined that the valves of the tanks had been shut off and that there was no fuel leaking from the tractor, but that some ammonia leaked into the water.
Some dead fish and elevated ammonia levels were found as far downstream as Monteith, about five miles southeast of Guthrie Center.
