Rainbow Lake | Show Low

Rainbow Lake, located near Pinetop-Lakeside in Navajo County, Arizona, is a 116-acre manmade reservoir situated in the scenic White Mountains region at an elevation of approximately 6,760 feet. Originally constructed in 1903 by Mormon settlers, who dammed Walnut Creek for agricultural irrigation, the lake today serves as a recreational hub offering fishing, boating, and wildlife viewing amidst a tranquil forested landscape.

Geography and Physical Characteristics

The lake covers roughly 116 acres and has an average depth of about 7 feet, reaching a maximum depth of approximately 14 feet. Surrounded by mixed ponderosa pine forests and grasslands typical of the high-elevation Mogollon Rim area, Rainbow Lake provides a cool, natural retreat throughout much of the year. The water is primarily fed by Walnut Creek, and the lake’s reservoir functions both for irrigation storage and recreational use. While the lake is owned by the Pinetop-Woodland Lake Irrigation Company, public access is managed by the Arizona Game and Fish Department via a small public landing on the northwest shore.

Fishing Opportunities

Rainbow Lake is a popular fishing destination, especially prized for its trout population. The Arizona Game and Fish Department regularly stocks catchable-sized rainbow trout during spring and early summer, providing excellent angling for both novice and experienced fishermen. In addition to trout, the lake supports naturally occurring species such as largemouth bass, channel catfish, bluegill, black bullhead, and green sunfish. However, the lake has also seen the illegal introduction of northern pike, a predatory fish that can affect the balance of native species. Anglers aged 13 and older are required to hold an Arizona fishing license, with an additional trout stamp needed for trout fishing.

Recreational Amenities and Access

A designated public boat landing on the northwest side offers access for fishing boats and recreational boating, with regulations limiting motorized boats to 10 horsepower or less to preserve the lake’s quiet and safe environment. The nearby Lakeside Campground provides visitors with essential facilities such as potable water, restrooms, and firewood, making overnight stays convenient for outdoor enthusiasts. The surrounding area features scenic hiking trails, picnic spots, and natural habitats for birdwatching and wildlife observation.

Environmental Management and Conservation Efforts

Rainbow Lake has faced ecological challenges, notably the invasive spread of Eurasian watermilfoil, an aquatic weed that can disrupt native ecosystems and impede recreational use. In response, local environmental organizations like the Show Low Creek Watershed Enhancement Partnership and the Rainbow Lake Coalition have implemented control measures, including the introduction of sterile white Amur carp-an herbivorous fish species known for consuming invasive weeds. To protect surrounding water bodies, stringent precautions are maintained to prevent the escape of these fish beyond Rainbow Lake.

Seasonal Considerations

The best times to visit Rainbow Lake are from late spring through early fall when weather conditions are favorable, water levels are stable, and stocking activities enhance fishing prospects. Summers offer warm days balanced by cool nights typical of the high-altitude climate, while spring and early summer bring vibrant foliage and active wildlife. Winters can be cold and snowy, occasionally limiting access or recreational activities.

Nearby Accommodations and Community

Pinetop-Lakeside, a small resort town adjacent to the lake, provides a range of lodging options including vacation cabins, inns, and hotels. Visitors seeking more extensive services or amenities may find options in the nearby town of Show Low, about nine miles south.
