Nonindigenous Occurrences: This species was collected from the White River (Rio Blanco County) in Colorado (Wick et al. 1981; Tyus et al. 1982; Woodling 1985). It also was introduced into the San Luis Valley (Rio Grande headwaters) in Colorado (Zuckerman and Behnke 1986). The Plains Topminnow has also been introduced into the Kansas drainage in Frenchman Creek, a tributary of the Republican River in Hitchcock County, Nebraska (Cross 1967; Cross et al. 1986), and the Cheyenne drainage in Wyoming (Gorges 1994).

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: Unknown.

Remarks: Voucher specimens: Nebraska (KU 4856).
