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: Unknown; possible bait bucket release.

Status: Established in Georgia.

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: It is uncertain whether this species is native to, or was introduced into, the upper Savannah drainage (Lee et al. 1980 et seq.; Dahlberg and Scott 1971b). Page and Burr (1991) apparently considered it native to the upper Savannah. According to Gilbert (personal communication), Notropis hypsilepis is not a common species and occurs in a very specific type of habitat (i.e., over shifting-sand substrate), thus, it would not be a species that would frequently enter bait buckets. Gilbert (personal communication) visited the site in the upper Savannah drainage (Timpson Creek) where the fish had been collected and noted that the site was not the species' typical habitat. Consequently, Gilbert favored the idea of introduction, although he cannot rule out the possibility of stream capture. The Timpson Creek site is very close to headwaters of the Chattahoochee River, and not particularly far from localities in the fish has been found (see Lee et al. 1980 et seq.).
