As a check on the accuracy of the damage analysis, a graph is provided of expected damage plotted against flood frequency for the combined Reaches I though IV (that is, the area of the Pawnee Creek overflow protected by the proposed improvements). Also shown on this figure is the total estimated damage which occurred along these reaches during the 1997 flood event, based upon damage estimates compiled by the Colorado Water Conservation District, the City of Sterling, and Logan County.
