Banks, Director Department of Water Resources Sacramento, California Dear Sir: There is submitted herevrith Bulletin No. 39-56 entitled, "Water Supply Conditions in Southern California During 1955 and 1956", prepared piirsuant to Chapter 832, Statutes of 1929. The report contains a discussion of water supply conditions in southern California during the water years 1954-55 and 1955-56, and features nearly 6,150 depth to ground water measurements, and two seasonal values for each of over 350 precipitation stations. During 1955 and 1956, there was a continuation of the drought which has prevailed in southern California since 1944. Precipitation and surface runoff v;ere both subnormal, ground water levels continued to de- cline and in coastal basins sea-water intrusion generally continued unabated. The utilization of imported water increased greatly and for a period of time during the summer of 1956, the demand exceeded the existing capacity to deliver this supply with the result that some requests to purchase imported water could not be met. This problem was somewhat relieved in September of 1956 by the completion of some additional import facilities. In areas where there is no supplementsil supply or such supply is limited, and where ground water basins are small and have limited carry- over storage, piroblems of water supply were becoming very critical by the summer and fall of 1956.

During this period the demand for this supply was so great that curtailment of deliveries was required o However , this problem was relieved in September of 1956 when additional pumps were installed on the aqueduct which substantially increased the capacity of this faciiitye In some areas ^ problems of water supply were becoming very critical by the summer and fall of 1956. This is particularly true in areas where there is no supplemental supply or where such supply is limited such as in the northern portion of San Diego County, In these areas existing surface storage was nearly exhavpted and existing* g-r^ound water basins are small and the limited carry over storage is nearly depleted. Aiithorlaiation The Legislatures by Chapter 832, Statutes of 1929., directed that exploration and investigation be conducted for the furtherance of a coordinated plan for the conservation, development and utilization of the water resources of California o As a result of this legislation, the Division of Water Resources undertook a continuing hydrologic investigation of the southern California area. Effective July S, 1956, the responsibilities of the Division of Water Resources, Department of Public Works, were assigned to the Department of Water Resources -2. pursuant to Chapter 52, Statutes of 1956o Prior Reports As a part of the investigation. Bulletin No, 39 was published in 1932, containing "Records of Ground Water Levels at Wells", Since 1932, water levels at selected wells have been published annually in Bulletins Nos, 39-A through 39-W, which was the last of the lettered series reports. This report. Bulletin No, 39=56, is the first of the numbered series reports and follows Bulletin No. 39=W with no interruption in the continuity of datao The locations and descriptions of the wells referred to in the earlier bulletins were published in Bulletin No, 39, and are shown on Kaps 1 through 8, accoiripanying that bulletin. The locations and descriptions of wells in the San Jacinto and Antelope Valleys were first published in Bulletin No. 39°'^ } and are shown on Maps 9 through 11 included in that bulletin. Seasonal precipitation data from United States Weather Bureau records, as well as from records at stations not included in official publica- tions of that agency, were first published in Bulletin No. 39-A and have been incorporated in all subsequent publications of the series. Monthly records from a few key United States Weather Bureau stations were first published in Bulletin No, 39-Do A map showing the location of precipitation stations for which seasonal records are published was included in Bulletin No. 39-A» Numerous other bulletins have been pviblished by the Department of Water Resources or its predecessor the Division of Water Resources, from 1930 to date, which include data on water use, ground water levels, quality of water, value and cost of water for irrigation, water losses and evaporation data, underground geology, and evaluation of overdraft on groundwater basins in southern Californiao These bulletins includes California State Department of Public Works, Division of Water Resources, "South Coastal Basin, A Symposium", Bulletin No. 32 o 1930.

Commencing in 191489 a general water supply summary for the southern portion of the State was added, containing information on precipitation, ninoff , surface reservoir storage, importations, water quality, and changes in ground water levels » Previous reports of this series have been prepared on a calendar year basis, in that water levels were presented for the period January 1 through Decemoer 31 of a given year, and other data such as precipitation and runoff, which are based upon some other 12=month period, were published for the seasonal year ending within the calendar year consideredo The preponderance of the data published in these reports are gathered from various cooperating agencies during the sumniero To enable more rapid dissemination of data, the period considered in these reports has been changed, beginning with this report, to generally correspond with the period of data collectiono To initiate this modification there is included herein precipitation and runoff records for the 195U=55 and 1955-56 seasons, and water level data for the l8=month period January 1, 1955 through June 30s 1956o To give an indication of ground water conditions at the end of the water year, water levels through September 30, 1956, have been included for certain "key wells" for which depths to ground water are obtained each montho The data are presented under four chapter headings as follows? (1) Introduction, (2) Water Supply, (3) Records of Ground Water Levels, and (Ii) Precipitation Records ^ Seventeen tables summarizing water supply data are included with the text of Chapter 2, and two plates pertaining to ground water data are bound at the end of the report o CHAPTER II. WATER SUPPLY Precipitation Precipitation during the seasonal years 19$J4=55 and 1955-56 was subnormal for the tenth and eleventh years since 19U3"Ui vdth precipitation indexes for southern California stations averaging about 7U per cent and 78 per cent of the mean, respectivelyo This protracted drought has been inter° rupted only by the wet year 195l=52o In the four seasons subsequent to the wet year 1951=52 , rainfall in San Diego has averaged about 63 per cent of mean and the accumulated deficit rainfall for the foiir-year period was l6oOii inches » This deficiency of rain- fall has caused the water=supply situation in San Diego County to become extremely critical, particularly in the agricultural areas in the northern part of the Countyo In certain portions of Coastal Los Angeles and Orange Counties, rainfall during the 1955=56 season was above normal primarily because of one exceptional storm which occurred during the period January 2$ through 27, 1956o This storm, which deposited as much as eight inches of rain on some parts of Coastal Los Angeles County, was unusual in that the amounts of precipitation in the mountains were proportionally much less than amounts on the plain = While the heavy precipitation on the flat, relatively impervious, developed areas along the coast resxilted in a high percentage of runoff from, and considerable inundation of, these areas, there was very little runoff from the mountains,, For this reason this storm was not of great significance with respect to water supply o In Table 1 there is presented precipitation indexes for selected areas in southern California during the two seasons 195U=55 and 1955-56 These indexes are arithmetical averages of the precipitation indexes for several stations within the area^ and are based on means for the 50-year period l897-=98 through i9li6°?4?o Seasonal precipitation records for individual stations are tabulated in Chapter IV o TABLE 1 PRECIPITATION INDEXBS FOR SELECTED AHEAS IN SOUTHERN CALIFORNIA 195i4=55 and 1955=56 s Index Area s 195ii=55 o 1955-^6 Chino 71 79 Coastal Plain 78 97 Riverside 71 68 San Bernardino 7ii 76 San Diego* 70 Ui San Fernando Valley- 80 97 San Gabriel Valley 73 85 * United States Weather Bureau Station Lindbergh Field,, San Diego Runoff In correlation to rainfall, runoff in southern California streams was far below normal during the 195ii°55 and 1955=56 water years o The estimated seasonal discharges of Sespe Creek near Fillmore were 18 per cent and 32 per cent of mean, respectively^ while the unimpaired runoff of Santa Ana River near Mentone was 3$ per cent and 29 per cent of mean^ respectively, for the two water years o Despite subnormal runoff from mountain and foothill areas, over 75i>000 acre=feet of water was discharged to the ocean in Los Angeles River during 195U=55 and in excess of 96,000 acre-=feet during 1955=56<. However, this runoff occurred largely from inpervious valley floor areas. During the previously described storm of January 25°27> 1956, a maximum instantaneous flow of about [(6,000 second-feet, consisting primarily of runoff from valley lands, was discharged into the Pacific Ocean in this river. Estimated seasonal natural runoff at selected stations in southern California during 195U-55 and 1955-56 is presented in Table 2, together VJith a comparison of mean, maximun., and minimuiti runoff for each station for the 53-year period, 189U-95 through 19i46-U7. -9- ■p o o o o O o o 9 § vO CM O ^O CM On C-- o CMIA OsfH NO O O f- o »\ w o\ o» o» e iH f^ On CA AJ o < H .§ «« iH r-l On 0\ On iH rH U^ c c lAlA CNOv C>v lA lA tA •H o IE y 1 O O CO CO C 1 1 S CO CO o O -CI CO ■LA^A OS CA On v^ \A 'LA (D On On oO co OO On CJn CN W iH iH fH r-l en a ■LA o o a o 8 o o 2 •4 o c t O O CO o o o W M M -:?

This constituted an over J4O per (jent increase during the two-year periodo Following in Table 3> there is presented the quantities of Colorado River water imported to various areas in southern California for the water years 1953-5ii through 1955=56, together with the percentage increase during each succeeding year» =11- TABLE 3 QUANTin AND PERCENTAGE INCREASE IN DELIVERIES OF COLORADO RIVER WATER TO COASTAL SOUTHERN CALIFORNIA i953=5a ^0 1955-56 Seasonal imports, g _ Fe r cent increase in acre-^fae t % 1953^5k % 195U- Area % % % s to s to g 1953° 5U § 195ii=55 § 1955°56 % 195ii°55 t 1955-56 Los Angeles County 160,.002 Yi^^'^.S'l 231,/730 11 30 San Diego Co-oTity 72 .,821 . lil<,5ll* lJ4."^06it 53 27 Orange County 62^009 S$M9 26,83U -10 -52 Riverside=San Bernardino Area _ 8j,?8it 21^31 .JLilii iM _i2 TOTALS 303^616 366,631 J432,o526 21 18 It will be Koted that aJ.l areas shoxred substantial increases in the utilisation of imported water^ ^^XmX the exception of Orange Countyo The primax=y reason for the dscreass in this Cou^^iity was a curtailment of spreading of untreated water in the f orebay areao TMs curtailment resulted from a rapid expansion of water demand which brcaght direct utilisation of Colorado River water to the approximate capacity of tne esrilsting aqueduct facilities diiring the Slimmer of 1956 and thus, substantially redueed the quantity of water avail- able for spreading o In addition^ deliveries to several cities in Orange County were curtailed daring Ar«gust of 1956 in order to protect District supplies, which r-esulted in volimtary rationing in the vicinity of Newport Beacho However, this problem was relieved in September^ 1956, when additional pumping units were installed and brought into serviceo Thj.s action increased the delivery capacity of the aqueduct from 600 to 1,<,000 second-feet in the reach between Parker Dam and San Jacinto Tunnel <> Problems of curtailment were also experienced in San Diego County daring the sujnmer and fall of 1956 because of -12= insufficient capacity of the San Diego Aqueduct, This problem was and continues to be particularly critical in agricultural areas in the northern part of the Cour.iy. Two major districts annexed to The Metropolitan Water District of Southern California during 1955 and 1956, and two districts annexed to the San Diego County Water Authority, Annexing to The Metropolitan Water District were the Central Basin Municipal Water District in Los Angeles County, which includes the Cities of Bell, Huntington Park, Lakewood, Lynwood, Maywood, Montebello, Signal Hill, South Gate, Vernon, and Whittier, and the Western Municipal Water District of Riverside County, vdiich comprises an area of about 317 square miles and includes the Cities of Corona, Elsinore, and Riverside, Annexing to the San Diego County Water Authority were the Otay Municipal Water District which comprises an area of approximately 86 square miles lying south and east of the City of San Diego, and the Valley Center Municipal Water District, comprising an area of about 83 square miles located east of the Rain- bow and Bueno Colorado Municipal Water Districts, In addition, there were several areas which annexed to constituent members of The Metropolitan Water District, or the San Diego County Water Authority. Annexing to the West Basin Municipal Water District were the Culver City-County territory areas comprising about 6U square miles, including Culver City, and the ABC territory consisting of small areas in the vicinity of Torrance. The Capistrano Beach-San Clemente area which annexed to the Coastal Municipal Water District added about 10 square miles to this District, including the City of San Clemente. In San Diego County, the KL Cajon Valley-Dry Island area comprising nearly 20 sqxiare miles previously annexed to the Helix Irrigation District, annexed to the San Diego County Water Authority, In addition, the Island area comprising several small tracts annexed concurrently to the Helix Irrigation District and the Authorityo =13. Approximately seven square miles of area annexed to the Bueno Colorado Municipal Water Districts three square miles annexed to Rio San Diego Municipal Water District, and five square miles in the vicinity of Sweetwater Reservoir annexed to the South Bay Municipal Water Districtc Storage in Siirface Reservoirs In most cases, there were only meager amounts of water in storage in southern California reservoirs during 1955 and this condition was only slightly improved in 1956c Usable storage in the eleven City of San Diego reservoirs on September 30 of both 1955 and 1956 was 130)4 per cent and lIioO per cent of capacity, respectively, and a large portion of this storage consisted of Colorado River water which was delivered to San Vicente and Hodges Reservoirs through the San Diego Aqueducts Storage in Lake Hemet on September 30 of both 1955 and 1956 was I08 and 2o8 per cent of usable capacity, respectively, while storage in Bear Valley Reservoir on these dates was l6o2 and 1<,6 per cent of visable capacityo With the exception of a short period in early 1956 Lake ELsinore has been dry for the past two and one=half years o Storage in Lake Mead increased slightly from l^Uoli per cent to kl'O per cent of usable capacity in the period between September 30. 1955 and September 30, 1956c The water surface elevation of Salton Sea was 23U08 feet below sea level on September 30, 1955, or Oo3 feet higher than a year previous. No change in elevation occurred in the period between October 1, 1955 and October 1, 1956..
