Whitehorse Basin cutthroat trout

The Willow-Whitehorse Basin cutthroat trout refers to a population segment of the cutthroat trout complex (Oncorhynchus clarkii) from the streams of the Whitehorse Basin (or the Coyote Basin ), southeastern Oregon. It is alternatively considered as a part of the Lahontan cutthroat trout subspecies (Oncorhynchus clarkii henshawi), or of the Humboldt cutthroat trout (O. c. humboldtensis) whose main range is in Nevada. These fish have adapted to live under extreme conditions, and can withstand water temperatures as high as 85 °F for short periods of time.
