Comments: Found in three springs in Pahrump Valley in Nye County, Nevada where it was the only native fish. Now exists only outside Pahrump Valley, where it was transplanted to prevent its extinction (Ref. 86798) Once common but extraction of water for irrigation eliminated species from native habitats. Protected as an endangered species (Ref. 86798). Also Ref. 5723, 27139. Status of threat: endangered; status same as 1989. Criteria: 1,4,5 (http://fisc.er.usgs.gov/afs/) (Ref. 81264).
