This is the terminus of the Los Angeles-Owens River Aqueduct, which brings water 338 miles from the eastern slopes of the Sierra Nevada to the City of Los Angeles. Begun in 1905, the great aqueduct was completed November 5, 1913. The Mono Craters Tunnel project, completed in 1940, extended the system 27 miles to its present northernmost intake near Tioga Pass.
