Feasibility studies by the Bureau of Reclamation have been completed to the point of definitely establishing the engineering and financial feasibility and layout of the basic East Side Division, but the final feasibility report has not yet been submitted, and only reconnaissance-grade designs and estimates have been made for the Initial Plan enlargement and extension to Wheeler Ridge. The opportunity exists for worthwhile cost savings to both the East Side development and the Pacific Southwest Plan through incorporation of the proposed enlargement. However, the need for additional water in the East Side Division is urgent, and the proposed East Side development has widespread and unified support within the San Joaquin Valley. The additional investigations needed for final refinement of the proposed combined development, therefore, are a matter of the utmost urgency, both to avoid any delay to East Side and for realization of the potential savings to the Pacific Southwest Water Plan. Cedar Springs-Perris Aqueduct The proposed conduit from Cedar Springs Reservoir to Perris Reservoir with connection to the Colorado River Aqueduct is planned for conveying 550,000 acre-feet annually of the supply imported through the enlarged California Aqueduct. This conduit would be scheduled for completion to permit deliveries in accordance with the need for additional water in southern California, now estimated to be required in 1981. Preparation of the plans and cost estimates for this aqueduct has been greatly facilitated by work previously accomplished for the State Water Project, but more investigations are needed for final refinement. Cedar Springs-Hayfield-Imperial Aqueduct Approximately 650,000 acre-feet annually would be conveyed from Cedar Springs Reservoir through the proposed conduit to the vicinity of the Colorado River Aqueduct a short distance westerly of the Hayfield Pumping Plant. From that location estimated costs are included in the plan for possible service extensions to Coachella and Imperial Canals. In accordance with current estimates, this proposed conduit from Cedar Springs Reservoir would need to be scheduled for completion by 1997 to maintain the guaranteed basic water supply of 7.5 million acre-feet or equivalent of water in the Lower Colorado River for consumptive use. Reconnaissance studies only have been made for this aqueduct. The route is such that no question exists concerning the practicability, but feasibility investigations are required to finalize layout and cost estimates. 25Epson Perfection 4870 Photo, 400 dpi, 8 bit, 13,830,144 byte
