The exception to the “Giant Trout are impossible to catch” rule, where you stand a really good chance of catching a trout over 8 pounds, is a place called Pyramid Lake and it lies just northeast of Reno, Nevada. Located on the huge Paiute Indian Reservation, Pyramid Lake is populated by Lahontan Cutthroat Trout which can grow to over 40 pounds. The Pyramid Lake Trout is the largest freshwater trout in the world.
