The redside dace Clinostomus elongatus is a small, laterally compressed cyprinid commonly found in small streams with moderate to high gradients, clear and cool water, and substrates of clean gravel, sand, or bedrock. Fish surveys in Winnebago County, Illinois, and Rock County, Wisconsin, conducted from 1997-2000 and 2010-2011 discovered the dace at a single site in Illinois in East Fork Raccoon Creek (Pecatonica River - Rock River Drainage). This is the first documented record of this species in Illinois and raises the known total of state native fishes to 192. Based on these surveys, C. elongatus is expected to periodically occur in the Illinois portion of the Raccoon Creek basin, and therefore should be considered a peripheral species in Illinois.
