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: Smith (1985) suggested that its presence in the Susquehanna River drainage, New York, may have been by way of dispersal through the Chenango Canal. However, this species was not reported from the Susquehanna drainage in a review of the species' distribution by Bailey (1954), and the Chenango Canal has been inactive since the late 1800s. Thus it is more likely due to a bait bucket introduction; Smith (1985) reports that the Brassy Minnow is frequently used as a baitfish. According to Etnier and Starnes (1993), the Tennessee record was based on a single specimen taken in 1973; they considered it a bait bucket introduction. Records in Colorado also may be the result of bait bucket releases. There is no information for means of its introduction into Utah.

Status: Reported from Colorado, New York, Tennessee, and Utah.

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: Pflieger (1997) noted that small populations of this species found in two tributaries of the upper Mississippi River in Missouri may be the result of recent bait bucket releases.
