Lake Katherine waterfalls in Palos Heights, Illinois on June 23, 2012. The waterfall tumbles over four separate falls, travels a distance of over 300 feet consisting primarily of rapids and small pools, and descends approximately 30 feet in height before joining the lake itself on the east side. This man-made waterfall attracts a wide variety of animals and plants, and benefits the lake by aerating the water before it joins the lake, supporting the plant and fish life in the 20-acre lake.
