Nonindigenous Occurrences: The Longnose Sucker was introduced into the Rio Grande and Colorado drainages of Colorado in the 1860s and 1870s (Woodling 1985) and Rocky Mountain National Park, Larimer County and Bent's Old Fort National Historic Site, Bent County, Colorado (Tilmant 1999), the Housatonic drainage of Connecticut (Whitworth 1996), and into Big Sandy Creek in the Upper Green River drainage and Yellowstone Lake in Wyoming (Brown and Graham 1954; Baxter and Simon 1970; Lee et al. 1980 et seq.; Hubert 1994). Stocked into Oliver and Bennett Reservoirs (also known as West and East Kimball Reservoirs, respectively) in Kimball County, Nebraska in 1956 (Jones, 1963).

Means of Introduction: Bait bucket release and contamination of trout stock (Brown and Graham 1954; Woodling 1985). Beckman (1952) reported a recent intentional introduction of this species into the Colorado River drainage in Colorado. No method of introduction given for Connecticut. First found in that state in 1992 (Whitworth 1996).

Status: Established in Colorado and Wyoming. Collected in Connecticut.

Impact of Introduction: Hybridization between native flannelmouth and bluehead sucker, and non-native white sucker Catostomus commersoni, Longnose Sucker C. catostomus, and Utah sucker C. ardens is occurring. Some combinations are fertile and will lead to introgression (Wyoming Game and Fish Department 2010).

Remarks: Tyus et al. (1982) gave a distribution map of the this species in the upper Colorado basin.
