Lake Palmdale is an artificial lake completed in 1924 along with the nearby Littlerock Reservoir and the Littlerock Dam. It is part of the California State Water Project and is fed by the California Aqueduct. It is located in the city of Palmdale near the city's southern edge, in the small Anaverde Valley between the San Andreas Fault and the base of Mount Tenhi.
Lake Palmdale is 2,980 feet (908.3 m) above sea level and is ringed by the hills of the San Andreas Fault and Mount Tenhi, except for a small pond on the lake's east side called Una Lake from which it is separated by the Palmdale Dam and Sierra Highway. The lake is 1.05 miles (1.69 km) in diameter at its greatest point (northwest to southeast), by 0.54 miles (0.87 km) in width (southwest to northeast). The lake has a surface area of 586.3 acres (237.3 ha) and contains 2 small islands.
Lake Palmdale is regularly stocked of fish and has a small pier-like dock that extends about .25 miles (0.4 km) into the lake from which members of the Palmdale Fin & Feather Club may use to fish from or take a small boat onto the lake. There are also many other small docks that run along the southwestern coast of the lake, also for use by the Fin & Feather Club. Use of Palmdale Lake for recreation is generally reserved for members of the Club. The nearby Littlerock Reservoir is a Los Angeles County operated park and is open to the public and can be used for boating, water skiing, fishing, and camping.
