The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Means of Introduction: Probably bait bucket introductions.

Status: Established in Utah; locally established in Wyoming. Presumably established in Idaho.

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.

Remarks: Although Simpson and Wallace (1978) listed this species as native to the upper South Fork of the Snake River in Idaho, we believe it is possible that it was introduced because of the fact that it was not collected from the upper Snake until the 1930s. In their list of fishes found in Idaho, Wydoski and Whitney (1979, Appendix 7) seemed to suggest that this species was introduced into the Snake River drainage and Bonneville basin in Idaho. However, Sigler and Sigler (1987) listed it as native to the eastern Bonneville basin which includes Idaho.
