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.

* HUCs are not listed for states where the observation(s) cannot be approximated to a HUC (e.g. state centroids or Canadian provinces).

Means of Introduction: Reportedly used as bait in 1951 in lower Colorado River (Miller 1952; La Rivers 1962). Transplanted from White River below Adams-McGill Reservoir to Railroad Valley in 1957 by Nevada Department of Wildlife (La Rivers 1962; U.S. Fish and Wildlife Service 1994e).

Status: Extirpated from sites where introduced in California and Nevada.

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: Listed as federally endangered species (U.S. Fish and Wildlife Service 1994e). Species has been adversely affected by introduced fishes including brown trout Salmo trutta, brook trout Salvelinus fontinalis, rainbow trout Oncorhynchus mykiss, cutthroat trout O. clarki, largemouth bass Micropterus salmoides, guppies Poecilia reticulata, mosquitofish Gambusia affinis, and goldfish Carassius auratus (U.S. Fish and Wildlife Service 1994e).
