† Populations may not be currently present.
Means of Introduction: The species was introduced accidentally into the San Luis Valley by the Colorado Department of Wildlife (Zuckerman and Behnke 1986). It was introduced into Rio Blanco County via unknown means, probably bait bucket release. Probable bait bucket introduction in Nebraska (Cross 1967). This species was first captured below Enders Reservoir, an area commonly fished with bait minnows, in 1959. The fish likely came from the nearby Platte River (Cross 1967).
Status: Reported in White River drainage (Woodling 1985); extirpated in Rio Grande drainage, Colorado (Zuckerman and Behnke 1986). Established in Nebraska.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
