This shapefile is the official boundary of the Western Native Trout Initiative. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2013 to reflect revisions from the Western Native Trout Initiative, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

Fishes of the Upper Colorado River Basin have one of the highest levels of endemism in the United States. The range and abundance of these fish has declined over the last century and continues to decline as a result of legacy impacts from past management practices, current water management, interactions with non-natives, and other impacts. Seven of these fish are considered imperiled by the American Fisheries Society and four are listed as endangered by the U.S. Fish and Wildlife Service. We applied a complementarity-based approach to develop priority ranks (0 – 1; low to high) for catchments in the Upper Colorado River Basin. We used methods and a framework that we had previously developed for the Lower Colorado...

The historic range of California golden trout (CGT) includes two watersheds draining the Kern Plateau of the southern Sierra Nevada Mountain Range in California. CGT are native to Golden Trout Creek (GTC) and the South Fork of the Kern River (SFKR), an area encompassing approximately 593 square miles (1,536 sq. km). They historically occupied GTC from the headwaters, with the possible exception of the upper reaches of some tributary streams and headwater lakes, downstream to a series of waterfalls near the mouth. In the SFKR, CGT were present from the headwaters downstream at least to the southern end of the present-day Dome Land Wilderness (Figure 1) and perhaps downstream of Lake Isabella. They may also be found...

Historically, Rio Grande Cutthroat Trout occupied all cool waters in the Rio Grande drainage, including the Chama, Jemez and Rio San Jose drainages, along with suitable waters of the Pecos and Canadian drainages. They currently live in only about 100 headwater streams, occupying 10 percent of their former range. They have a yellowish green-gray to gray body with scattered black spots, and a densely spotted tail. Adults grow up to 12-13 inches long. The Rio Grande Cutthroat has officially been designated as the New Mexico State Fish.
