The Cascades are a registered State Histor-ical Landmark. They are where the 338-mile Owens River Aqueduct terminates, bringing fresh water to L.A. The aqueduct’s construction, which finished in 1913, is a fascinating—–and murky—–tale of government corruption and outright theft. It was made famous by the film Chinatown. Owens Valley residents, watching their water disappear into pipes bound for Los Angeles, successfully sued the city. Some of their water began returning in late 2006.
