The U.S. Fish and Wildlife Service operates the Ash
Meadows Fish Conservation Facility (AMFCF), which supports the recovery of the
endangered Devils Hole pupfish. The facility includes a 100,000-gallon tank
that mimics the natural environment of Devils Hole. The AMFCF is located in close
proximity to Devils Hole within the Ash Meadows National Wildlife Refuge. However,
it is not part of the wildlife refuge.
