Trout are not the first fish most people think about when considering the fish found in Iowa, but the coldwater springs of the Driftless Area are perfect for native Brook Trout and stocked Rainbow and Brown Trout. Early agricultural practices that increased farming yield had a negative impact on stream erosion and water quality. Recent restoration efforts have helped trout populations rebound. Trout fishing fees help to maintain and restore high quality trout streams. Trout are confined to the upper pool, which is connected to the lower stream by a waterfall. The lower stream demonstrates the diversity of small fish species that also rely on healthy, coldwater, spring-fed streams.
