Abstract:
Littlerock Dam, located in the Angeles National Forest in southern California, was originally designed and constructed as a multiple-arch structure. Consisting of 28 arches, it has a maximum height of 190 ft (58 m) and a crest length of 720 ft (220 m). It was designed by John S. Eastwood, a pioneer in the design and construction of multiple-arch dams. When it was completed in 1924, Littlerock Dam was the highest multiple-arch dam in the United States. The dam provides a vital water supply ofr both the Palmdale Water District and the Littlerock Creek Irrigation District.
