Nonindigenous Occurrences: Introduced into the Santa Clara River in the Upper Virgin drainage in Utah (Miller 1952).

Ecology: Flannelmouth Suckers are generally found in pools and deep runs of medium to large rivers within the Colorado River basin, with young fish found in aread of slower water velocity than adults (Bezzerides and Bestgen 2002).

Means of Introduction: Introduced in Utah as discarded bait (Miller 1952). Introduced to lower Colorado River by Arizona Game and Fish Department for black fly abatement (Mueller and Wydoski 2004).

Status: Established.

Impact of Introduction: Unknown.

Remarks: Abundance and distribution of Flannelmouth Suckers in the Colorado River basin have been greatly reduced from their historical distribution.  Only occurs in 25% of historical habitat in lower Colorado River basin. Extirpated from the Gila River basin, and the majority of the mainstem lower Colorado River below the Grand Canyon. Occupies 50% of historical distribution in upper Colorado River basin (Bezzerides and Bestgen 2002).

The species was translocated to the lower Colorado River near Bullhead City, Arizona, in 1976 (Mueller and Wydoski 2004), as a reintroduction effort (Minkley and Marsh 2009).
