Littlerock Reservoir
To serve the irrigation needs of the orchards, Littlerock Dam was built in 1924. The dam is an Eastwood cement multiple arch buttress dam and is one of several built in the Western U.S. It is considered a historical architectural monument. It is located in the
Angeles National Forest
adjacent to Littlerock and serves as a recreational facility for off-road vehicles, fishing, boating, equestrian trails and camping. This is a popular retreat and can be enjoyed year-round.

Littlerock Dam
In late 1917 plans for a large storage dam on Little Rock Creek were first announced in the “Antelope Valley Ledger Gazette.”
Between 1918 and 1922, engineer John S. Eastwood created three different designs for a dam at two possible locations on Little Rock Creek.
On June 26, 1922, Bent Bros signed a contract with the Palmdale Water Company to construct the dam; the next day the Littlerock and Palmdale Irrigation Districts approved the contract, and Bent Bros began assembling the necessary equipment.
Final approval of the design for Eastwood’s multiple arch dam at its current location was given on November 4, 1922, and work began immediately; that same day it was reported that “mixer plant equipment and crusher" had already been installed, and that "spouting equipment" for pouring concrete was on the site.
Seventeen months later, Littlerock Dam, the highest reinforced concrete multiple arch dam of its time, was declared complete April 1, 1924. No joke! It filled to capacity for the 1st time in early April 1926, after heavy rains, and water poured over the small spillway.
