Nonindigenous Occurrences: Introduced into the North Fork of the Feather River, Sacramento River Drainage, California (Moyle 2002); Lake Mead, Nevada (Miller 1952); and into the Duchesne, Price, and Strawberry River drainages in Utah (Sigler and Miller 1963).

Means of Introduction: Hypothesized as stocked for bait or bait bucket release for introduced populations in Utah and Nevada (Miller 1952; Sigler and Miller 1963). Population in Sacramento River drainage, California, likely resulted from a water diversion from the LIttle Truckee River for irrigation (Moyle 2002).

Status: Common in the Duchesne River drainage, and established in the Price River drainage, Utah (Sigler and Sigler 1996).

Impact of Introduction: Unknown.

Remarks: Sigler and Miller (1963) identify the specimen from Lake Mead listed by Miller (1952) as bluehead sucker (Catostomus discobolus; given as Pantosteus delphinus in Sigler and Miller 1963).
