available through www.itis.gov
Identification: La Rivers (1962); Sigler and Sigler (1987); Page and Burr (1991).
Size: 15 cm.
Native Range: Historically in the White River system, Nevada. Most populations
are extirpated, and the species now exists only at Flag Springs in Nye County,
Nevada (Page and Burr 1991; U.S. Fish and Wildlife Service 1994e).

† Populations may not be currently present.
* 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.
