The Mammoth Lakes Basin (Twin Lakes, Lake Mary, Lake George and Lake Mamie), located above Mammoth Lakes, offers wonderful angling opportunities for Rainbow, Brook and Brown Trout. All four lakes are stocked regularly throughout the season. As a bonus, the Mammoth Lakes Basin also receives heavy summer plants of trophy-sized trout, some weighing in at 10 to 12 pounds. These prize fish are fun to catch and delicious to eat. All lakes offer boat rentals, with canoes, pontoon boats and tackle shops available at some locations.
