These are considerably higher than previous estimates of the cost of con- struct~o!l' due part~y to increases in the cost~ of materials and labor, and partly to reVISlOns made III the plans of constructIOn. It may be noted that the esti- mates of the State Division of Water Resources in Bulletin 25 on the State Water Plan for the capital cost of the complete initial development of some- what similar units of the Central Valley Project was $157,900,000 in 1930, and that the proposed revenue bond issue of $170,000,000 voted upon in 1933 was expected to finance units whose capital cost was estimated to total $167 954 500 including a 30 per cent donation toward the cost of materials and lab~r by the Federal Government, and interest at 4 per cent on the remainder of the cost. Estim~tes submitted in connection with hearings on the appropriation bills have mcreased from $170,000,000 in 1940 to $228,000.000 in 1941, to $265,000,000 m 1942, and to $333.000,000 m 1943. The 1942 estimate of $265,000,000 was based on pre-war prices and took into account most of the increased costs due to design changes in various project features. The 1943 f:SOZOO (6) .., <C' estimate is based on wartime conditions which involve increased costs of labor and materials and added expense that will result from an accelerated wartime program. Aside from the marked differences in costs of materials and labor in 1943 as contrasted to 1933, the increased estimates of cost have been due to several extensive changes in plans. Shasta Dam, originally planned for a height of 420 feet and a s~orage. capacity of 2,940,000 acre feet, has been raised to a height of 602 feet mcludmg an extra 122 feet due to excavation necessary to obtain a satisfactory foundation. Storage capacity was increased to 4,500,000 acre feet, with corresponding increases in other dimensions of the dam, area cov- ered by wat<:r, cost o~ relocating: the railroad and other utili~i~s, and a larger power capaCIty. The 10creased SIze of Shasta Dam, the addItIon of Keswick pam, other ad~ed power generation and transmission features, and changes In costs have mcreased the estimated cost of this part of the project to $194,251,500 compared to $95,000,000 for the units contemplated in 1933. When the original Central Valley Project was advocated for State con- struction in 1933, only preliminary engineering studies had been made of the Delta Cross Channel, and the estimated cost was $3,867,300 compared to the present maximum estimate of $37.118,700. Alternative plans under study may cost less. In the ongInal proposal, the cost of mOVIng water up the San Joaquin Valley to Mendota were estimated at $22,269,300. Present estimates are nearly double that amount, or ~1,078,200. Here the plans have been altered to pro- VIde future capacity for IrrIgahon of 100,000 acres of new land. Estimates for the Madera and Kern Canals are about the same as in 1933, but modified plans presented in 1943 call for a considerable reduction in the use of scarce mate- rials for these units. Friant Dam, estimated in 1933 as costing $13,646,800, is now eshmated as $19,635,500, and its capacity, on the recommendation of the Army Engineers, raised from 400.000 acre feet to 520,000 acre feet. . These fig;.rres, with. su~h qualifi~atio~s as ,:re. ne~essary in making any direct companson! are sIgmfica.nt chIefly ~n theIr IndIcation of the changed aspect of the project, and are Important m the effect they will have on the annual carrying costs which will be necessary to amortize the cost of the project from .its water, power, and other revenues, over the next 40 years. Alth~ugh deSIgn changes on various features. of th~ project and expense due to pnce Increases have added matenally to ItS e'sttmated cost the increased stora~e capaci,ty in .the reservoirs and the greatly increased electric generating capacIty prOVIded m the Shasta Power Plant, at Keswick Dam and in other features over and above the original State plan, has added to the benefits created by the project and will provide increases in project income. Present Status of the Project The 'project as a whole is somewhat less than half completed, although constructlOn work has been under way for the past six years and over $125,000,000 has been expended. Aside from the limited Use of ';"ater from ~me ca~al in Contr~ Cost~ County, it is as yet not far enough along to be of Imf!1edIate y;;e for Its deSIgnated purpos~s of navigation, flood control, irri- gahan, sallmty control, and hydro-electrIC power production. Although the project was mtended to be prImarIly a supplemental water supply project for relIef of ~ntlcal w~ter shor~ages In ~he Cen~ral Valley farming areas, those phases of Its operatton are stIll some distance 10 the future.
