    The primary management objectives of the refuge are to restore the stream channels and springs to as near a natural condition as possible and to optimize available stream habitat for recovery and delisting of Moapa dace. The springs are thermal in nature and have an average annual water temperature of 90 degrees Fahrenheit at the point of discharge. Water quality is good, although high in calcium carbonate.
