Description: A large area along the nearly dry Amargosa River which contains 

 many small desert springs, waterholes, and sloughs. Three fishes of very 

 restricted distribution are found here: Cyprinodon diabolis (the one pool which 

 contains the entire population of the species is now under disjoint control by 

 Death Valley National Monument); C. nevadensis (a highly differentiated spe- 

 cies with two recognized subspecies and numerous races found in the various 

 discontinuous waters); Empetrichthys merriami (probably extinct).

Encroachments: There have been past incidences of successful aquarium fish in- 

 troductions in these waters; one person attempted to establish an aquarium fish 

 hatchery in the area. There have also been attempts to divert water, and suc- 

 cessful introduction of large mouth bass in some spots.
