A slight sheen, indicative of petroleum, can be seen on the surface of the water

The Iowa Department of Natural Resources (DNR) is investigating an oil spill that entered the West Nishnabotna River from a truck stop near Avoca. The spill follows a complaint of discharged petroleum at the same Eagles Landing Flying J Truckstop from this spring that the DNR was still investigating and working to help clean up when the June 24 spill was observed.
