15 on225Q includes service to the San Joaquin Valley areas. As an integral part of this plan of development, therefore, an additional 3,000 c.f.s. increment would be added to bring an additional new supply of 1,400,000 acre-feet to the east side San Joaquin Valley. This would include conveyance through the California Aqueduct to Wheeler Ridge pumping plant, and from that location through the new canal to Tule River. In addition, off-stream reservoirs at Hungry Hollow site on Deer Creek, and Owens Mountain site on Little Dry Creek would be included for storage. . Estimated capital costs (reconnaissance) of the additional facilities proposed for east side service are $375,000,000. Annual OM&R costs are estimated at $1,450,000. Estimated costs of pumping the water for serving east side San Joaquin Valley areas are $9,400,000. Subsequent early authorization of additional works would be required to provide: increased East Side Division service through facilities on the east side of San Joaquin Valley from the Delta to connect at Tule River with the features proposed under this plan. The transfer of additional water of a high quality through the Sacramento-San Joaquin River Delta will require modification of the present channels, which were constructed as part of the extensive levee system to protect the low elevation Delta lands from flooding. To accomplish this, the Bureau has proposed that a new channel around the periphery of the Delta will provide the highest possible water quality--total dissolved solids will average less than 200 parts per million. In addition, the channel will provide maximum protection to the large resident and anadrornous fisheries that use the present Delta channels. The estimated capital cost of the Delta Peripheral Canal is $70,000,000, with an annual OM&R cost, including power, of $800,000. This facility should be authorized for Federal construction, with appropriate financial participation by the State of California. ., Further development of water in the Central Valley Basin and increased diversions from the Delta) either for use in southern California or within the Central Valley, also expands the urgency for the Kellog Unit to offset adverse effects which may occur to water supplies relied upon by Contra Costa County. These facili- ties are proposed as an integral part of the Central Valley Project pr~ncipally for water quality improvement, although other multiple- purpose functions would be served, for the urbanized and highly . industrialized Contra Costa County. This area is now being served in part by the Central Valley Project. This proposed unit also would provide operational flexibility for the Central Valley Project
