Show -26- D. Specific Description, Physical Data and Costs as of November 30, 1956, of the Principal Additions to the Distribution System of the Colorado River Aqueduct Project. 1. San Diego Aqueduct: This supplies untreated Colorado River water to the constituents of the San Diego County Water Authority, and extends from the west portal of the San Jacinto Tunnel to the San Vicente Reservoir of the City of San Diego, a distance of 71.1 miles. The portion of this aqueduct operated by the M.W.D. lies between the San Jacmto Tunnel and the north end of the San Luis Rey River Siphon, a length of 36.3 miles, and includes the 1,400 acre-foot San Jacinto regulating reservoir. The original construction of the San Diego Aqueduct to a designed capacity of 85 c.f.s. was completed in November, 1947. This original construction included a 200 c.f.s. capacity section from the San Jacinto Tunnel to the San Jacinto Reservoir, 165 c.f.s. capacity tunnels in the 4.4 miles of the line where tunnels were required, and provisions for double-barreling the remaining pipeline sections when water demands necessitated. Increased demands prompted the construction of the deferred second barrel which was commenced in September, 1952, and completed in September, 1954. The San Diego Aqueduct now has a diversion capacity from the Colorado River main aqueduct of 200 c.f.s., a capacity of 180 c.f.s. from the San Jacinto Reservoir to the Fall-brook Turnout, and 165 c.f.s. south from this |
