† Populations may not be currently present.
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.
