28. Forming part of the West Branch California Aqueduct and named after a distinctly shaped rock-face, which reservoir was completed in 1973 and subsequently became a popular destination for recreation and water-sports?
From Quiz The County of Los Angeles
Answer:
Pyramid Lake
Pyramid Lake and the rest of the West Branch California Aqueduct are part of a massive water management system that takes water from northern California and redistributes it to the hotter, drier and far more populous areas of southern California. It might sound simple, but it includes over 1,100 kilometres (700 miles) of canals and pipelines, more than 20 dams, pumping stations capable of lifting water over the 880 metre (2,900 feet) high Tehachapi mountains and a hydroelectric power system.
Pyramid Lake was created in 1973 by the construction of Pyramid Dam on Piru Creek - a tributary of the Santa Clara River. The pyramid-shaped rock that it is named after is an earthwork created during the construction of US Route 99, part of which now lies under the lake. Recreational activities available at Pyramid Lake include various visitor centres, picnic areas, boating, jet-skiing and fishing.
Bicycle Lake is a dry lake in San Bernardino County, Dog Lake is in Yosemite National Park and Square Lake is a mountain lake in Tehama County.
