High in the Sierra, one of the rarest subspecies of cutthroat trout hangs on in a harsh, austere environment. Here, where feeder creeks to the famous Lake Tahoe meander through high-country meadows, some of the last remaining populations of Lahontan cutthroat swim. By protecting this habitat, Trout Unlimited hopes to keep this important stock of native trout intact, both as a recreational resource and as a potential brood stock for future restoration work that involves these rare fish.
