<br />ASSEMBLY IN'l'1!;l{Ul (JO.M.MITTI~E ON WATER
<br />
<br />of the desert area and the Colorado River areas of southeastern Cali-
<br />fornia. It can be seen that the area's needs are primarily agricultural,
<br />although there is a limited amount of municipal and industrial need.
<br />It is not expected that significant additional water will be required in
<br />this area during the next few decades.
<br />Projections in the revised Pacific Southwest Water Plan are shown
<br />in the following table:

<br />of this area to be served through 1990 by the State Water Project.
<br />Mojave Water Agency ______________________ 50,800 acre-feet maximum state
<br />entitlement in 1990
<br />Antelope Valley-East Kern Water Agency____ 138,400 acre-feet maximum state
<br />entitlement in 1990
<br />Source: Pacific Southwest Water Plan, January 1964, Table 13.
<br />Coastal areas of the southern California counties of r~os Angeles,
<br />Orangc, l~iverside, and San Diego, are inclnded in this table for illus-
<br />tration to show that of the total requirements of 4,820,000 acre. feet in
<br />the yeljr 2000 this represents an increase of 2,660,000 acre-feet over pres-
<br />ent requirements for coastal areas but represents an increase of only
<br />320,000 acre-feet for the Colorado River and desert areas during that
<br />same period. In addition, the desert areas shown in the Bnreau of Hecla-
<br />mati on estimates on this table include areas served by the Mojave Water
<br />Agency and the Antelope Valley-East Kern Water Agency, which in the
<br />aggregate, have contracts for nearly 200,000 acre-feet of water a year
<br />from the State Water Project.
<br />Thus, it can be seen that relatively small increases in water supply
<br />are going to be needed to serve the area of southeastern 'California,
<br />assnming no increase in irrigated agricultnre.
<br />'rable XVIII briefly summarizes the water supply from the Colorado
<br />River and shows that at the present with California permitted to take
<br />its entire contract entitlement, agricultural users may take up to a
<br />maximum of 4,150,000 acre-feet a year. Under conditions with Cali-
<br />fornia restricted to 4.4 million acre-feet a year the agricultural areas
<br />would be entitled to 3,850,000 acre-feet. The agricultural areas are not
<br />using the entire 4,150,000 acre-feet available to them at the present.
<br />Hepresentatives of the agricultural agendes served in that area ex-
<br />plained that increased quantities of water will be required in"future
<br />years as the salt content of Colorado River water increases. In fact,
<br />they have stated that the entire amount of water salvaged under Pacific
<br />Southwest Water Plan proposals could be utilized for that single
<br />purpose.
<br />No additional cutback in agricnltnral water would be suffered in
<br />the a.rea until California's diversions from the Colorado River per year
<br />dips below 3,850,000 acre-feet per year, an unlikely occurrence.
