Alternative Plans for Delivering 1,200,000 Acre-Feet Additional Water to Southern California Seven alternative reconnaissance plans for conveyance of an additional annual yield of 1,200,000 acre-feet of water to southern California are presented in this section. A tabular summary comparing these plans is attached. In brief, these alternative plans all rely on conserving the additional 1,200,000 acre-feet of water in two proposed reservoirs on the Trinity River system with diversion to Sacramento River. As indicated in the discussion of the alternative plans, these proposed reservoir storage systems on Trinity River and appurtenant diversions should be authorized for construction and operation by the Bureau of Reclamation. The additional water supply is considered to be conveyed to southern California through the following alternative routes: (a) Enlargement of California Aqueduct along west side of San Joaquin Valley through Tehachapi pumping plants and tunnels, and thence to Perris Reservoir (Alternative Plans 2 and 3). (b) Enlargement of East Side Division on easterly side of San Joaquin Valley; thence connecting with California Aqueduct immediately north of Tehachapi Mountains, from which location the California Aqueduct would be enlarged to its terminus at Perris Reservoir (Alternative Plan 1). (c) Sierra Nevada tunnel diversions of East Side San Joaquin Valley streams to connect with California Aqueduct south of Tehachapi Mountains, and thence through enlarged aqueductEpson Perfection 4870 Photo, 400 dpi, 8 bit, 14,399,488 byte
