Nonindigenous Occurrences: The leatherside chub was introduced into Strawberry Reservoir, Utah, circa 1948 and into the Price River (Colorado drainage) prior to 1963 (Sigler and Miller 1963; Tyus et al. 1982). It also has been introduced into the Dirty Devil River (a Colorado River tributary) in southeastern Utah (specimens as NCSM) (W. Starnes, personal communication), and the Fremont River, a tributary of the Dirty Devil (Tyus et al. 1982). It may have been introduced into the Snake River drainage and the Bonneville basin, Idaho (Wydoski and Whiney 1979; see remarks); and the upper part of the Snake River in Wyoming, where it first was collected in 1934 (Sigler and Miller 1963).

Means of Introduction: Probably bait bucket introductions.

Status: Established in Utah; locally established in Wyoming. Presumably established in Idaho.

Impact of Introduction: Unknown.

Remarks: Although Simpson and Wallace (1978) listed this species as native to the upper South Fork of the Snake River in Idaho, we believe it is possible that it was introduced because of the fact that it was not collected from the upper Snake until the 1930s. In their list of fishes found in Idaho, Wydoski and Whitney (1979, Appendix 7) seemed to suggest that this species was introduced into the Snake River drainage and Bonneville basin in Idaho. However, Sigler and Sigler (1987) listed it as native to the eastern Bonneville basin which includes Idaho.
