Deer Creek averages about 50 feet in width. The upper river is low in gradient and shallow with rocky riffles and runs and scattered deep pools. The habitat is excellent for the stocked trout. One area of interest that is unlike any other in Rocks State Park is along Route 24 upstream of Rocks-Chrome Hill Road. The River flows through large boulders and falls at least 10 to 12 feet with white water not unlike that seen at Great Falls on the Potomac River. It is a scenic view of Deer Creek you don't want to miss. The lower river is low in gradient with rocky riffles, sandy runs and scattered sandy pools. The large, slow pools and runs are attractive resting areas for the spring migratory hickory shad and river herring.
