North America: Virgin and Gila River systems (both lower Colorado River drainage) in Utah, Nevada and Arizona, USA. Now believed extirpated in Gila River system. Listed as Vulnerable (VU - D2) in IUCN 2004 and listed in Appendix II of CITES.
Inhabits fast sandy runs of small to medium rivers, usually in warm turbid water. Sometimes in pools (Ref. 5723). Most commonly found in shallow, moderately flowing water over shifting sand substrates (Ref. 26186). Spawning in the Virgin river begins in April to May and continues through August (Ref. 26186).
