Nonindigenous Occurrences: This species is known from the Virgin River in northwestern Arizona (Minckley 1973; Lee et al. 1980 et seq.) and from several areas in New Mexico including the Rio Grande Basin, Rio Hondo (Pecos drainage), the Mimbres River, Largo Creek (Little Colorado River drainage), and the Zuni River (Koster 1957; Minckley 1973; Lee et al. 1980 et seq.; Propst et al. 1987; Sublette et al. 1990).

Means of Introduction: Unknown; probable bait bucket releases. Introduced as early as the 1950s into parts of the Rio Grande basin of New Mexico. The Rio Hondo, Mimbres, and Largo Creek introductions all occurred in the 1960s (Sublette et al. 1990).

Status: The Largo Creek population was extirpated by 1990, but the New Mexico populations in Rio Hondo and the Mimbres remain established (Sublette et al. 1990). It is locally established in a portion of the Rio Grande basin (Sublette et al. 1990). Reported but not known to be established in the Zuni River, New Mexico, and in the Virgin River, Arizona (Lee et al. 1980 et seq.). The status of the Virgin River population is unknown.

Impact of Introduction: Unknown.

Remarks: Koster (1957) reported that the species is used as a baitfish.
