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: Authorized introductions for sportfishing. First introduced in Arizona in 1971 (Rinne 1995) and in Idaho in 1939 (Linder 1963). According to Marcuson (1984), Col. Sherman and his brother carried 13 specimens in a coffee pot from Mulkey Creek (tributary of South Fork Kern River) to Cottonwood Creek in CA in 1876.  E. H. Edwards then planted some of the Cottonwood Creek fish into Cottonwood Lakes in 1981.  A "spawning station" was established at the Cottonwood Lakes in 1917 which became the source of Golden Trout eggs.  Betweeen 1928 and 1938, the eggs were shipped to the National Fish Hatchery in Bozeman (but name is now the Fish Cultural Development Center).  Various lakes in MT were stocked with eggs from the Cottonwood Lake station (Marcuson 1984).

Status: Established populations recorded for California, Montana, Utah, and Washington. Populations in the high-elevation lakes in the Ruby Mountains, Nevada, no longer exist (Deacon and Williams 1984). Also extirpated in New Mexico.

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: The introduction into New Jersey (Stiles 1978) may have actually been based on stocking of "Golden Trout", a mutant form of rainbow trout raised in hatcheries (Behnke, personal communication).
