Taxonomic CommentsThree subspecies (cataractae, dulcis, and smithi) have been described; other populations probably deserve taxonomic recognition (Page and Burr 1991). Hybridizes with Rhinichthyes osculus, Gila pandora, and Campostoma anomalum (Sublette et al. 1990).

Range Extent CommentsWidest range of any North American minnow; generally distributed north of 40 degrees north latitude from coast to coast; north to the Arctic Circle in the Mackenzie River drainage; south in the Appalachian Mountains to northern Georgia, south through the Rocky Mountains into the Rio Grande drainage of Texas and northern Mexico, and south along the Atlantic coast to Virginia; common in northern U.S., fairly common in west but absent from Alaska and from western drainages south of the Columbia and Coos river drainages (Page and Burr 1991). Subspecies cataractae: east of the Continental Divide. Subspecies dulcis: Pacific basin. Subspecies SMITHI: formerly in hot springs in Banff National Park, Alberta.
Occurrences CommentsThis species is represented by a large number of subpopulations and locations.
Threat Impact CommentsSee Lanteigne (1988) for discussion of extinction of subspecies smithi due to introgressive hybridization with subspecies cataractae (marsh created by Cave and Basin Hotsprings, 1.7 km SW Banff, Alberta, Canada); initial decline of smithi is attributed to introductions of non-native fishes, periodic cessation of spring flow related to public use of hot springs, and periodic spillage of sewage from the public facilities (Miller et al. 1989).
