Honorable Harvey 0. 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.
Very truly yours,

WATER SUPPLY CONDITIONS
IN SOUTHERN CALIFORNIA DURING
1955 and 1956
CHAPTER I o INTRODUCTION
This report is the 25th of a series begxin in 1932 in recognition of
the need for collecting and publishing basic hydrologic data for use in the
continuing study of water problems in southern Calif orniao This report is
similar to previo\is reports of the Bulletin Noo 38 series in nearly all
respects o However, the report designation has been changed frpm a letter to a
niunber designation indicating the year for 'fcriiich the data are published, and
the period for which data are presented has been modified to facilitate more
rapid publicationo The data contained herein were collected by numerous
agencies and made available to the Department of Water Resources for
publicationo
In general, the protracted drought which commenced in southern
California in 19iiU=Ii5 continued through the seasonal years 1951i'=55 and 1955=56o
During each of these two years the rainfall at ten representative stations
throughout southern California showed a deficiency which averaged over five
and one-half inches » In correlation, runoff in southern California streams was
far below normal = Runoff in Arroyo Seco near Pasadena, for example, was 18 per
cent and 30 per cent of the long-time mean, respectively, for the two years »
The continuation of the drought combined with rapid development
resulted in an ever-increasing demand for water^ Local supplies continued to
be inadeq;xate, and storage in surface reseirvoirs not receiving imported water
was nearly depletedo In many areas draft on ground water aquifers was in
excess of recharge thereto, with the result that water levels continued to
decline and, in coastal areas, sea-water intrusion generally continued
unabatedo Supplemental water was iraiported from the Owens Valley through the
aqueduct of the City of Los Angeles to the present maximum practicable
capacity of the facility, which is about 320,000 acre^feet per yearo Importa=
tion of water from the Colorado River through facilities of The Metropolitan
Water District of Southern California increased approximately 65^000 acre-feet
per year during 19Sh~SS and 1955='56;, and during the summer of 1956 the aqueduct
was operated at the approximate capacity of then existing facilities. 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

Resources, "South Coastal Basin, A Symposium", Bulletin
No. 32 o 1930.

Scope of Report
The early reports of the Bulletin No, 39 series were limited to
publication of records of ground water levels in the Santa Ana, San Gabiriel,
and Los Angeles River Valleys, and the West and South Coastal Plainso
-h'
Subsequently^ precipitation records were added and the area covered by the
report extended to include the San Jacinto and Antelope Valleys. 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

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.

Importation
During the water year 195U~55i, (October 1 through September 30),
City of Los Angeles, Department of Water and Power imported 316,300 acre«=feet
of water from the Owens River=Mono Basin through the Los Angeles Aqueduct,
while during 1955"56, 321,1^25 acre-feet of water were imported from this
sourceo This import represented over 70 per cent of the total water used by
the City during these years » Except for short periods of shutdown for routine
maintenance and inspection, the Los Angeles Aqueduct was operated at full
capacity for the two-year periods
Importation of Colorado River water through facilities of The
Metropolitan Water District of Southern California amounted to about 366,600
acre=feet during the water year 19Sh=5b , and about 1^32,500 acre-feet during
1955-56 1. 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»

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.. Storage in selected
reservoirs in, or supplying water to, southern California on September 30 of
both 1955 and 1956 is presented in Table k'

Construction of Hydraulic Structures
Construction was completed on several important dam and reservoir
projects during 1955 and 1956;, and construction was initiated on others which
are now in various stages of completionr The majority of these facilities are
being built for water conservation and/or flood control purposesr In Table $,
there are listed the major resenroir projectein the southern California area
■vdiich have been under construction during the past two years together with
approximate dates of starting and completion^ and the agency responsible for
the workc
Several major facilities for the distribution of supplemental water
were under construction or implemented during 1955 and 1956o In January, 1956,
lining of Tscolote Tunnel was completedo This tunnel is part of the diversion
from Cachuma Dam to the coastal region near the Cities of Santa Barbara,
Goleta, MontecitOj, and Garpenteria, In June of 1956., Rainbow Municipal Water
District dedicated a |ljOOOc,000 distribution system near Fallbrook, This
system., which includes Davis and Griswold Heservoirs and 20 miles of pipe
line., serves an area of some 36^.500 acres in San Diego County,,
Many parts of the aqueduct and distribution system of The Metropolitan
Water District of Southern California were under construction or completed
during 1955 and 1956= In September of I9563 installation was completed on two
additional pumps for each pumping station on the aqueducts These additional
pumps increased the capacity of the aqueduct from 6OO to 1^000 second-feet.
Major distribution facilities under construction included the Middle Feeder, a
lOo 3-mile section extending from the softening plant at La Verne to Baldwin
Park in Los Angeles County, and the Lower Feeder which extends through the City
of Corona into Orange County^ In June of 1956, The Metropolitan Water District
obtained, through election, authorization to issue short-=term notes for

expansion. Major features of the expansion program will include installation
of the last three pTimps at each of the aqueduct's five pumping stations,
construction of 22 miles of additional siphons, and doubling' the capacity of
Lake Mathews, the terminal reservoir of the aqueducto
Quality of Water
Although there were some instances of localized pollution caused by-
improper disposal of sewage and industrial waste, the principal water quality
problem in the southern California area continued to be sea-water intrusion »
In many coastal ground water basins, including Oxnard Plain, West Coast Basin,
East Coastal Plain Pressure, Santa Margarita Valley, San Luis Rey Valley, and
Mission Valley, encroachment into ground water aquifers by sea water continued
unabated during 1954-55 and 1955-56. Mineral analyses of samples from selected
surface sampling stations and wells in southern California are presented in
Tables 6 and 7.

Changes in G:.'°ound tfater Levels
Characteristic of the past dej^ade, there was a continuing decline of
water levels in groxutxi water basins of southern California during 1955 and 1956,
and in many basijis^ levels observed during this period were the lowest of
recordo Summarized on the following pages are water level conditions for many
of the ground water basins delineated on Plate lo Also shown on Plate 1 are
locations of selected wells for which flvictuations of ground water levels are
shown on Plate 2o In Tables 8 through 17^ there are presented changes in ground
water level elevations from the fall of 195ii to the fall of 1955 5 and from the
fall of 1955 to the fall of 1956, for selected wells in the South Coastal Area
and Antelope Valley, together with the maximiun and minimum water levels of
record at such wells s
Antelo pe V alley
Consumptive use of ground water in Antelope Valley has exceeded
replenishment for more than a quarter centvry , with the result that there has
been a steady decline in gro^jTid water levels in this areao In the period
between the fall of 1951 and the fall of 1955s the average decline was 2 ,,6 feet,
while from the; fall of 1955 to the fall to 1956, the average decline exceeded
seven feet« New minimum elevations of record were reached at most of the wells
during 1955 or 1956 and in the vicinity of Palmdale depths to water as great as
300 feet were observed. To generally represent conditions in the Valley during
1955 and 19565 changes in ground water level elevations at 15 wells in the
Valley are presented in Table 80

Santa Clara River V alley
Oxnard Plain Basin » There was a sharp decline in ground water
levels throughout most of the Oxnard Plain Basin during the 195U'=55 season,
with levels in many instances approaching and in some cases exceeding the
record lows observed during the fall of 19510 The following season, however,
saw a small recovery due, at least in part, to increased direct use of water
imported from Santa Felicia Reservoir of the United Water Conservation Districto
Oxnaivi Forebay Basin o There was a general decline in ground water
levels, averaging about five feet per year, during both 195^4-55 and 1955-56
seasons despite water spreading by the United Water Conservation Districto
During 195Ii-55j water spread by this organization at its Saticoy spreading
grounds was approximately 12^000 acre"=feeto During 1955-56, this organization
spread a combined total of approximately 17,200 acre=feet at its Saticoy and
El Rio spreading grounds o
The general condition of decline in ground water levels prevailed in
other basins in Ventura County during this same period » This is shown by the
data presented in Table 9 entitled "Changes in Ground Water Levels in Ventura
County".

San Fernando Valley
There was a continued decline in ground water levels in this Valley
during the water years 195ii"55 and 1955=56, averaging nearly eight feet for
the two-year period., in all but the northwest portion of the area. In many
instances, levels recorded in the fall of 1956 constituted h-istoric minimum
observations. In the northwest portion of the valley, however, no significant
changes in 1 excels wers noted during the two=year period » The changes in
ground water levels at selected wells in the Valley during 195^1-55 and 1955-56
are presented in Table 10 <,

San Gabriel Valley
£.,
Raymond Basin e Grormd water IstsIs in the Western Unit of this Basin
declined about two feet during each of the two water years 19Sh-SS and 1955-56,
while in the Eastern Unit the declines averaged about 7 and 10 feet, respective-
ly. The use of ground water in the Raymond Basin Area has been controlled by
Court decree since July 1, 19i;Uo However, beginning July 1, 1955^ the Court,
by "Modification of Judgment" entered on April 29, 1955, permitted increased
extractions amounting to over 4O per cent in the Western Unit and over 35 per
cent in the Eastern Unite
Mai n San Gabriel j^sino Ground water levels declined an average of
about eight feet during the two years 1951=55 and 1955=56^ and new lows of
record were observed at many of the wells. Changes in ground water levels at
selected wells throughout the San Gabriel Valley for the period fall 1951^ to
fall 1955, and fall 1955 to fall 1956, are presented in Table ll.

Coastal Pl ain., Los Angeles County
Montebello Forebay Area o Ground water levels in this area declined
an average of about 15 feet during the water years 195ii-55 and 1955-56, and
historic low observations were recorded in many instanceso This decline
occurred despite the fact that 32,600 acre-feet of water was spread to recharge
the ground water aquifers of the areao
Central Coastal Plain Pressure Area . Pressure levels continued to
decline in the Central Coastal Plain Pressure Area during 195ii-55 and 1955-56,
and in the fall of 1956 were the lowest of recprd in nearly all cases » Pumping
depressions were definitely noticeable in the area north of Culver City and
north of Signal Hill, where levels dropped to lOii and 117 feet below sea level,
respectivelyo Average decline over the area was about 12 feet during the two
years o
West Coast Basin s There was a definite rise in piezometric levels
throughout most of the West Coast Basin diiring 195ii=55, particularly in the so=
called "trough area" located in the southeastern part of the Basino This rise
is attributed to an approximate 30 per cent reduction in extractions from the
Basin as a result of an "Interim Agreement" to curtail pumping among parties
pumping about 85 per cent of the annual extractions from the Basin, The
curtailment began on June 1, 1955? and the relief was s\ifficient to cause
water level recovery to begin in June rather than in late fall which is the
normal case,. This effect may be seen from inspection of the hydrograph of well
B=ll5g on Plate 2o Comparison of water levejLs on corresponding dates in the
fall of 1955 and 1956 would indicate a lowering. However, comparison of low
points of 1955 and 1956 indicates a slight rise in levelo
=39=
Changes in ground water level elevations occurring from 19Sh to 1956
at 16 wells in the Montebello Forebay Area^ Central Coastal Plain Pressure Area,
and West Coast Basin are presented in Table 12 »

Upper Santa Ana Valley
, Chino Basin o There was a general decline, averaging about five feet,
in ground ■water level elevations in Chino Basin over the two-year period fall
i 19Sh to fall 19565 and in many instances, low elevations of record were
established during this period. In the Upland=Clareinont-Ontario District
located in the northwest part of the Basing, depths to water ranging from ii50 to
nearly 600 feet were not uncommon j, and it is reported by local farmers that
such depths were approaching the economic pumping limit for prevailing
agricultural practices,
I Bunker Hill Has in » Declines of as much as 35 feet were noted in water
level elevations in this Basin during the period fall 195h to fall 1956o The
decline averaged over 20 feet for observed wells, and in nearly all instances,
historic low elevations were recorded in the fall of 1956<. Declines of this
magnitude suggest that ground water supply problems may be becoiTdng very
serious in this Basino
Changes in ground water level elevations for lli selected wells
throughout the Upper Santa Ana Valley are presented in Table 13 o

Coast al Pl ain<i Orange C otiaty
East Coagtal pLain Pressurgp Piesometric levels in the East Coastal
Plain Pressure declined about two feet in the period between the fall of 195U
and the fall of 1956. However, most of th2.s drop occurred during the first
yeare In general^, levels ranged from about 20 to over iiO feet below sea level,
and the existing landward hydraulic gradient is permitting the continued
intrusion of sea water, particularly in the Talbert zone.
Santa Ana For ebay Areae In general^- water levels in thj.s area
increased during 195ii-55 and decreased again during 1955=56o However, in most
parts of the area, levels remained below sea level during both years j the
fifth and six^-Ji consecutive years of this conditiono The fluctuations in
water levels described is undoubtedly closely related to cooperative spreading
operations of the Orange Co-jiity Water District, Orange County Flood Control
District J and the Orange Coi;nty Municipar. Mater District. During the 195U-55
season these agencies spread about 58sUOO acre^feet of water from all sources,
Hcwe''''er-s as stated previously, during the summer of 1956 the amount of
Colorado River water available for spreading was restricted, with the result
that only about 2658OO acre-feet of water was spread during the 1955"56
season. The effect of curtailed spreading is undoubtedly reflected in the
decrease in water levels experienced during 1955=$6o
Depths to ground water and net changes in ground water elevation
for five basins in the Coastal Plain of Orange County are presented in
Table li4.

San Jacinto Basin
During the period between the fall of 195U and the fall of 1956,
ground water levels in the San Jacinto Basin declined an average of about
seven feet, and minimuin elevations of record were observed at many of the
wells in the area. Because of limited runoff in the San Jacinto River during
the two-year period, only about lIiO acre^feet of water were spread at the
artificial recharge grounds of the Riverside County Flood Control and Water
Conservation Districto However, the water shortage problem in this Basin was
relieved to some extent in April, 1955, when importation of Colorado River
water through the facilities of the Eastern Municipal Water District was
initiated c Depths to ground water and changes in ground water elevations at
eleven selected wells in the Basin are presented in Table 15.

San Luis Rey Valley
In the vicialty of Oceanside, ■water levels declined to as much as 22
feet below sea level in the fall of 19,56, and sea=water intrusion continued to
be a major problem in this area,, The average decline in water levels through-
out the Valley in the period fall 195ii to fall 1956, was over six feet, and in
most instances, levels obserr^ed in the fall of 1956 were the minijnuiir of record.
In Table 16, there are presented depths to water and changes in elevation for
selected wells in both Bonsall and Mission Basins o

feet during the period between fall of 195U and fall of 1956, bringing the
ground water level elevations throughout most of the western half of the Basin
below sea level. Net changes in ground water elevations, as well as maxLraum
and minimum ground water level elevations of record are presented in Table 17o

CHAPTER III. RECORDS OF GROUND WATER LEVEI5
A tabulation of distance to water sxirface for approximately 1,000
wells in Los Angeles, San Gabriel, and Santa Ana River Basins and in Antelope
Valley is presented on the pages that follow. These records are a continua-
tion of those published in previous reports of the Bulletin 39 series.
As stated in Chapter I, records presented in this report are for the
calendar year 1955 and, in most instances, the first six months of 1956.
Records for certain "key wells", for which data are received monthly, have
been extended to September, 195^. This was done to give an indication of
condition prevailing at the end of the 1955-5^ water year.
Following is a list of abbreviations used in this report:
