Convict Lake is a stunning alpine lake in Mono County, California, within the Eastern Sierra Nevada near Mammoth Lakes. It is renowned for its crystal-clear turquoise waters, dramatic mountain backdrop, excellent trout fishing, and a colorful history tied to its name.
Physical Description and Geography
Convict Lake is a naturally formed glacial lake, carved by glaciers during the Pleistocene epoch and impounded by a terminal moraine. It sits in a narrow box canyon within the Sherwin Range of the Sierra Nevada, part of the Inyo National Forest and adjacent to the John Muir Wilderness.
- Elevation: Approximately 7,580–7,850 feet (2,310–2,393 m) above sea level.
- Size: Surface area of about 168–170 acres (roughly 0.68–0.69 km²). It is oblong in shape, with a maximum length of about 0.9 miles (1.4 km) and maximum width of 0.4 miles (0.6 km).
- Depth: One of the deeper lakes in the region, with a maximum depth of around 140 feet (43 m) and an average depth near 88–100 feet. This depth contributes to cold, stable water temperatures ideal for trout.
- Water Characteristics: Exceptionally clear, turquoise-blue waters with high transparency (Secchi disk depths up to 50+ feet reported in studies). It is oligotrophic (low nutrient levels), with cold temperatures, high dissolved oxygen, and near-neutral pH, supporting limited plankton and benthic life but pristine conditions overall.
The lake is fed primarily by snowmelt and glacial runoff from the surrounding watershed (about 16 square miles) and drains into Convict Creek. Steep granite walls and talus slopes rise sharply around it, creating a dramatic, enclosed setting.
It was like a scene from “Grumpy Old Men”, when a man walked into the store in a tuxedo while I am purchasing a fishing license.

Surrounding Landscape and Scenic Beauty
Convict Lake is often praised as one of the most picturesque and accessible lakes in the Eastern Sierra. It is boxed in by towering peaks, with Mount Morrison (12,241–12,279 feet / ~3,731–3,745 m), the prominent high point to the southeast, dominating the skyline. Other rugged granite features, such as Sevehah Cliff, add to the vertical drama.
The shoreline features a mix of forests (including aspens that turn brilliant gold in fall), meadows, and rocky areas. A popular ~3-mile (relatively flat, ~200 ft elevation gain) loop trail encircles the lake, offering continuous views and easy access for hikers, photographers, and anglers.
Seasonal Beauty:
- Summer: Vibrant turquoise waters reflecting blue skies and peaks; wildflowers and lush greenery.
- Fall: Stunning aspen colors against the mountains and lake reflections.
- Winter/Spring: Snow-capped peaks, potential frozen surfaces, and dramatic storm light.
Visitors and reviews frequently describe it as “breathtaking,” “peaceful,” “magnificent,” and one of the most beautiful drive-to lakes, with easy access just a couple of miles off Highway 395. It has appeared in commercials and ads due to its photogenic qualities. The combination of clear water, alpine scenery, and relative seclusion (despite accessibility) makes it exceptional.
History and Naming
The Northern Paiute (Mono) people traditionally knew the area and called the lake something like Wit-sa-nap (associated with legends of water babies or spirits). Early settlers referred to it as Monte Diablo (“Mountain of the Devil”).
Its current name stems from a dramatic 1871 incident: On September 17 (or 23 per some accounts), 29 convicts escaped from the Nevada State Prison in Carson City. A posse pursued one group led by Charlie Jones to the lake area. A shootout ensued, killing posse members including Robert Morrison (a Benton merchant) and Mono Jim. The lake and creek were renamed Convict Lake in memory of the event, while the tallest peak was named Mount Morrison. Most escapees were eventually recaptured.
A resort/camp has operated here since the late 1920s (originally Raymer’s Camp, later Convict Lake Camp), with current facilities including cabins, a restaurant, and boat rentals.
Wildlife, Recreation, and Ecology
The lake supports a robust fishery, primarily rainbow trout, brown trout, and brook trout, stocked regularly. Its cold, oxygenated, clear waters produce large, healthy fish (some in the 8-pound range). Shore fishing, boat/kayak/float tube angling, and the loop trail are popular.
Other recreation includes camping (Convict Lake Campground with ~85–88 sites), hiking into the backcountry, photography, and wildlife viewing. The area has bears, so proper food storage is required.
Ecologically, it remains relatively pristine with low productivity, though managed for recreation and stocking. Water quality is generally excellent.
Practical Information
Convict Lake is located at approximately 2000 Convict Lake Road, Mammoth Lakes, CA, easily reachable from U.S. Highway 395. It is open seasonally for many activities (typically late spring through fall for full access), with winter offering a different serene beauty. Facilities include parking, boat launch, resort amenities, and trails.
In summary, Convict Lake exemplifies the raw beauty of the Sierra Nevada: a deep, clear glacial lake nestled in a dramatic canyon, framed by towering peaks, and offering accessible yet profound natural splendor alongside a touch of Wild West history. It remains a favorite for locals and visitors seeking tranquility, adventure, and unforgettable scenery.
