than satisfactory standards, and the situation likely will be aggra-
vated by other developments in the delta. The investigation is
oriented to providing substitute storage and conveyance works for
the areas not protected by the operation of the Central Valley project.
The Contra Costa County Water District has contributed $50,000
toward the cost of the investigation. The study is scheduled for
completion in fiscal year 1966.
East Side division, initial phase..
This investigation is designed to assist in solving the overdraft on
ground water supplies in San Joaquin Valley and the need for re-
placement of lands in specialty crops being lost to urbanization.
Although Central Valley project imported supplies have materially
assisted in preserving the area's agricultural economy, the overdraft
on this ground water supply is continuing. Urbanization of lands
previously devoted to citrus groves, truck crops, and forage crops in
Southern and central California areas is creating a demand for re-
placement acreage. The rapid increase in population is creating cor-
responding increases in demands for food products, especially perish-
able fruits, vegetables, and dairy products which depend on forage
products from nearby agricultural areas. Features of this division
will consist of multipurpose dams and reservoirs on the major tribu-
taries and an extensive conveyance system to transport excess waters
of the northern rivers, such as the American River, to the water-
deficient areas of the south. These latter areas embrace some
3,000,000 acres of land which will require a large amount of supple-
mental water to balance the ground water overdraft and achieve
optimum production. It is anticipated the initial phase will pro-
vide a supplemental water supply for about 780,000 acres and a full
supply for 160,000 acres of new land and include power generating
facilities with an installed capacity of 150,000 kilowatts. The pro-
posed report on the initial phase has been completed. The final
report is scheduled for completion in fiscal year 1964.
East Side division, ultimate phase...
As pointed out in connection with the initial phase, there are some
3,000,000 acres of land which will ultimately require a substantial
amount of supplemental water annually. The initial phase as now
contemplated will provide a water supply for some 940,000 irrigable
acres, but it is planned in such a manner that it can be extended or
enlarged to import additional water supplies from the Yuba River
and other areas of excess water as the need develops in future years.
The service area studies now completed on the initial phase are
concentrated on compact blocks of irrigable land. Between these
blocks there are about 2,000,000 acres which will have a supple-
mental water requirement. Some of the latter areas have already
expressed an interest in obtaining additional water.
It was originally proposed to examine these latter areas as part of
the planning on the ultimate phase when the demand for additional
importations developed in the future. In order to insure equal
opportunity for sharing in the benefits of the importations under the
initial phase, however, land capability studies of the remaining
service areas were initiated in fiscal year 1962 with completion sched-
uled for fiscal year 1966. These data ultimately will be required in
connection with the studies of facilities to extend and enlarge the
initial phase, although the latter studies, which involve some
$450,000 of the total costs shown here, are not scheduled to be under-ppy hon
taken until after fiscal year 1969.
