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.

Nonindigenous Occurrences: This species was introduced into the spring-fed inlet to Lytle Pond on the Fort Carson Military Reservation, El Paso County, Colorado in July 1980 (Miller 1984).  Arkansas Darters were historically found in the Arkansas River at Canon City, Colorado in the same area.  Museum specimens were found from 1889 to 1913 (UMMZ 61589, UCM 406, USM 6336, USNM 63371.5).  This stocking was in a pond that was previously fishless (Miller 1984), as a conservation measure.

Means of Introduction: According to Miller (1984), the Lytle Pond introduction was carried out by the Colorado Division of Wildlife as part of an experimental transplant, apparently for the preservation of an imperiled or uncommon species. The introduction involved 34 specimens taken from a spring slough along Fountain (about 5 kilometers south of town of Fountain), El Paso County, Colorado.  This species was stocked as a conservation measure.

Status: Apparently established in Colorado in a single site within its native range, but in a non-native waterbody. Numerous small darters were observed in Lytle Pond in October 1982; one male and six females, in reproductive condition, were trapped in March 1983. Miller (1984) indicated that a quantitative census has yet to be made.

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: Prior to introduction, the inlet and Lytle Pond were unoccupied by fish (Miller 1984). All, or most of, the Fort Carson Military Reservation in El Paso County is within the Fountain Creek system (Arkansas River drainage).
