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.

† Populations may not be currently present.

Means of Introduction: Most introductions apparently originated from bait bucket releases. In western Colorado, the species may have been introduced by bait bucket transfers or accidentally stocked as a contaminant with other species, although upstream expansion from Utah cannot be ruled out (Woodling 1985). It possibly spread downstream into the Big Horn River of Montana from Wyoming (Brown 1971). The species has been introduced widely since about the 1930s (Poss and Miller 1983).

Status: Established in many areas of the Colorado River above and below Glen Canyon dam (Poss and Miller 1983). Presumably established in other localities mentioned.

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: Poss and Miller (1983) discussed the introduction history of this species and provided a dot distribution map distinguishing native and introduced records. According to Lee et al. (1980 et seq.), many records represent natural occurrences (e.g., the Yellowstone River drainage records in Montana and Wyoming, the Cheyenne River records in Wyoming and South Dakota, the non-Pecos records in the Rio Grande Basin in Texas); however, Poss and Miller (1983) concluded these populations were introduced. Holton (1990) found the species to be more widespread in Montana than previously thought, inhabiting the Little Missouri and Yellowstone drainages and the Fort Peck Reservoir area; thus, he suggested that the species may be native to the state. Tyus et al. (1982) gave a map showing its distribution in the upper Colorado basin. The Plains Killifish has never been collected in North Dakota (Steinwand, personal communication) even though it has been collected in the Yellowstone River in Montana near the Montana/North Dakota state line (Elser et al. 1980). That area of western North Dakota has been intensively surveyed (Steinwand, personal communication), so it is not likely that the species was overlooked.
