View of Mulholland Dam and Hollywood Reservoir (also known as Lake Hollywood) both designed and built by engineer William Mulholland, for which the Dam is named after. Construction of these began on August 1923, and they were completed just one year later, in December 1924. The man-made reservoir, which holds more than 2.5 billion gallons of water, was filled in 1925 it is part of the Owens River Aqueduct system and provides Los Angeles with most of its drinking water. The Dam is located in Weid Canyon, east of Cahuenga Pass it is 210 feet high, 933 feet long, and 16 feet wide at the crest with a maximum depth of 183 feet. 172,000 cubic yards of concrete were used for the construction of the Mulholland Dam. Today, the surrounding area is open to hikers and joggers, however, since the lake provides drinking water, swimming and boating is restricted.
