The Lahontan cutthroat trout is the largest cutthroat trout species, and is the state fish of Nevada. The species is native to the Lahontan basin of central Nevada and mid-eastern California. The present distribution is restricted to a few lakes and streams within and outside the historic range. Dark olive backs and reddish to yellowish sides frequently characterize the Lahontans found in streams, while the sides of lake-dwelling Lahontans are often silvery. The largest recorded Lahontan trout weighed in at 41 pounds.
