The Lahontan cutthroat is native to drainages in the eastern Sierra. Introduced rainbow, brook, and brown trout have replaced the Lahontan cutthroat in most of its native range. Overharvesting, degraded habitats, and competition with introduced trout species are some of the factors that have led to the extirpation of these trout from their native waters. These trout are listed as threatened under the Federal Endangered Species Act. Angling opportunities for these trout are limited, but in time, as more populations are successfully restored, the Department hopes to open up more waters for anglers to experience catching one of these beautiful native trout.
