<br />RIVER PROJECT 'the application provides for 3,500,000 acre-feet of storage
<br />. in the Oroville Reservoir; 16,000 acre-feet of storage in
<br />Crow Canyon reservoir near Haywardj 201100 acre-feet
<br />in a reservoir near Milpitas and 6,000 acre-feet of storage
<br />in Evergreen reservoir south of San Jose.
<br />
<br />A second applibation provides for direct diversion of
<br />11,000 second-fee.t and storage of 3,500,000 acre-feet per
<br />year to be used for power purposes at the Oroville dam
<br />and the afterbay power plants.
<br />A third applic~tion is supplemental to the first two and
<br />is designed to r$serve addit.ional unappropriated water
<br />for presently estimated ultimate water requirements in cer-
<br />tain areas to be served under the California Water Plan.
<br />
<br />The filing of the three appli.::ations by the State Director
<br />of Finance is the first step in assuring an adequate water
<br />supply for the project and is in accordance with the pro-
<br />cedure which was followed some years ago when the State
<br />filed applications for unappropriated water on the main
<br />streams of the Sacramento and San Joaquin Rivers. Some
<br />of these earlier applications were assigned to the Bureau
<br />of Reclamation and now involve waters being used in the
<br />Central Valley Project.

<br />STATUS OF WATER RIGHTS FOR THE PROGRAM
<br />
<br />IRRIGATION BENEFITS
<br />
<br />The ultimate consumptive irrigation use requirement of
<br />the Feather River Service Area, including the areas now
<br />having prior rights to Feather River water, is estimated to
<br />be 631,000 acre,feet per year over and above effective
<br />rainfall. Assuming an irrigation efficiency of 65 per cent,
<br />the gross requirement of the area would be 970,000 acre-
<br />feet per year.
<br />
<br />The study shows that with the available excess water in
<br />the Delta supplemented by releases from Oroville Reservoir
<br />it will be possible to obtain a continuous flow for diversion
<br />of 3,930 second-feet without deficiency, or about 2,845,000
<br />acre-feet annually.
<br />
<br />On August 25, 1951, it was announced that State Direc-
<br />tor of Finance James S, Dean had filled applications with
<br />the State Division of Water Resources for a total of
<br />3,156,000 acre-feet of water to carry out the purposes of
<br />the Feather River Project.
<br />
<br />The filings (subject to Sections 10505, 11460-11463 of
<br />the State. Water Code) included: 311,000 acre-feetfor the
<br />Feather River service area;
<br />
<br />POWER BENEFITS
<br />
<br />The incidental hydroelectric energy obtainable at gen-
<br />eration from the power plants at Oroville and Oroville
<br />Afterbay Dams is 232,000 kilowatts of dependable energy.
<br />
<br />127,000 acre-feet for the Santa Clara-Alameda county
<br />diversioni
<br />
<br />945,000 acre-feet for the West Side and southern part
<br />of the San Joaquin Valley; and
<br />
<br />1,773,000 acre-feet for areas south of the Tehachapi
<br />mountains.
<br />
<br />FLOOD CONTROL BENEFITS
<br />
<br />The Feather River and its tributaries are among the prin-
<br />cipal contributors to flood flows in Sacramento Valley.
<br />There have been a number of notable floods recorded with-
<br />in relatively recent years, which, if uncontrolled under pres-
<br />ent conditions, would have caused heavy damages, loss of
<br />property, and hazard to life and health. The Feather River
<br />and its tributaries on the Sacramento Valley floor are in-
<br />c1udedin the Sacramento River Flood Control Project.
<br />However, the degree of protection provided by existing
<br />leveed channels is not comparable with protection afforded
<br />
<br />13
<br />
<br />Under the application, water will be used for irrigation,
<br />domestic, municipal. industrial, recreation. flood control,
<br />salinity control and navigation control purposes.
