Moapa dace-Wildlife and Habitat









 The unique geology of the Moapa Valley National Wildlife Refuge makes it an important location for native wildlife. There are five major thermal springs in Moapa valley, three of which are located within refuge boundaries. The warm springs habitat supports many unique species. Moapa Dace, White River Springfish, Moapa Pebblesnail, and Moapa Riffle Beetles are all endemic to Moapa Valley, which means they are found here and nowhere else in the world.

    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.
