FOREWORD

MAILING ADDRESS ULARA Watermaster PO Box III. Rm. 1466 Los Angeles. C A 90051

As Watermaster for the Upper Los Angeles River Area (ULARA), I am pleased to submit this report of the water supply conditions in ULARA during the 1985-86 Water Year. It was prepared in accordance with the provisions of the Final Judgment, signed by the Honorable Harry L. Hupp of the Los Angeles Superior Court on January 26, 1979. On April 30, 1985, Judge Vernon G. Foster replaced Judge Hupp as Judge of Record for the San Fernando Judgment.

This report describes the water rights in each basin, lists the allowable pumping for the Water Year 1986-87, and indicates the water in storage to the credit of each party as of October 1, 1986. In addition, this report includes background information on the history of the San Fernando Case; information as to each basin and the ULARA in total on water supply, ground water extractions, ground water levels, quantities of imported water use, recharge operations including amounts thereof, water quality conditions; and other pertinent information occurring during the water year pursuant to the provisions of the Judgment.

During this past Water Year, I contacted Judge Foster regarding an amendment to the Upper Los Angeles River Area Judgment. This amendment would allow individuals other than those specified in the Judgment to pump water from the ULARA for the purpose of evaluation and cleanup of the basin. This amendment to the Judgment has been delayed in being implemented, but I do not anticipate any problems in obtaining this amendment. All parties to the Judgment are expected to stipulate to this amendment.

I wish to acknowledge and express appreciation to all parties that have provided information and data which were essential to the completion of this report.

Sincerely,

~I.~~ MELVIN L. BLEVINS

Senior Hydrologic Engineer and ULARA Watermaster (Reg. C.E. No. 12863)

I. INTRODUCTION

Upper Los Angeles River Area (ULARA) encompasses all the watershed of the Los Angeles River and its tributaries above a point in the river designated as Los Angeles County Department of Public Works (LACDPW) Gaging Station F-57C-R, near the junction of the Los Angeles River and the Arroyo Seco (Plates 1 and 2). ULARA encompases 328,500 acres, composed of 122,800 acres of valley fill, referred to as the ground water basins, and 205,700 acres of hills and mountains. ULARA is bounded on the north and northwest by the Santa Susana Mountains; on the north and northeast by the San Gabriel Mountains; on the east by the San Rafael Hills, which separate it from the San Gabriel Basin; on the south by the Santa Monica Mountains, which separate it from the Los Angeles Coastal Plain; and on the west by the Simi Hills.

ULARA has four distinct ground water basins. The water supplies of these basins are separate and are replenished by deep percolation from rainfall and from a portion of the water that is delivered for use within these basins. The four ground water basins in ULARA are the San Fernando, Sylmar, Verdugo, and Eagle Rock Basins (Plate 2).

The San Fernando Basin, the largest of the four basins, consists of 112,000 acres and comprises 91.2 percent of the total valley fill. It is bounded on the east and northeast by the San Rafael Hills, Verdugo Mountains, and San Gabriel Mountains; on the north by the San Gabriel Mountains and the eroded south limb of the Little Tujunga Syncline which separates it from the Sylmar Basin; on the northwest and west by the Santa Susana Mountains and Simi Hills; and on the south by the Santa Monica Mountains.

The Sylmar Basin, in the northerly part of ULARA, consists of 5,600 acres and comprises 4.6 percent of the total valley fill. It is bounded on the north and east by the San Gabriel Mountains; on the west by a topographic divide in the valley fill between the Mission Hills and the San Gabriel Mountains; on the southwest by the Mission Hills; on the east by the Upper Lopez Canyon Saugus formation along the east bank of the Pacoima Wash; and on the south by the eroded south limb of the Little Tujunga syncline, which separates it from the San Fernando Basin.

The Verdugo Basin, north and east of the Verdugo Mountains in ULARA, consists of 4,400 acres and comprises 3.6 percent of the total valley fill. It is bounded on the north by the San Gabriel Mountains, on the east by a ground water divide separating it from the Monk Hill Subarea of the Raymond Basin, on the southeast by the San Rafael Hills, and on the south and southwest by the Verdugo Mountains.

1

The Eagle Rock Basin, the smallest of the four basins, is in the extreme southeast corner of ULARA. It comprises 800 acres and consists of 0.6 percent of the total valley fill.

History of Adjudication

The water rights in ULARA were established by the JUDGMENT AFTER TRIAL BY COURT in Superior Court Case No. 650079, entitled The City of Los Angeles, a Municipal Corporation, Plaintiff, vs. City of San Fernando, it al., Defendants, signed March 14, 1968 by the Honorable Edmund M. Moor, Judge of the Superior Court. Pri-or to the judgment, numerous pretrials were held subsequent to the filing of the action by the City of Los Angeles in 1955 and before the trial commenced on March 1, 1966.

On March 19, 1958, an Interim Order of Reference was entered by the Court directing the State Water Rights Board, now known as the State Water Resources Control Board (SWRCB), to study the availability of all public and private records, documents, reports, and data relating to a proposed order of reference in the case. The Court subsequently entered on June 11, 1958 an "Order of Reference to State Water Rights Board to Investigate and Report upon the Physical Facts (Section 2001, Water Code)."

A final Report of Referee was approved on July 27, 1962 and filed with the Court. The Report of Refer~e made a complete study of the geology, insofar as it affects the occurence and movemen~ of ground water and the surface and ground water hydrology of the area. In addition, investigations were made of the history of the horizontal and vertical locations of the beds, banks, and channels of the Los Angeles River and its tributaries: the areas, limits, and directions of flow of all groundwater within the area: the historic extractions of ground water in the basin and their quality; and all sources of water, whether they be diverted, extracted, or imported, etc. Said Report of Referee served as the principal basis for geological and hydrological facts for the original Trial Court Judgment in 1968 and Decision of the Supreme Court in 1975 (14 Cal 3d 199, 123 Cal Rept 1) and the Trial Court Judgment on remand on January 26, 1979.

The City of Los Angeles filed an appeal from the Judgment of the Trial Court with the Court of Appeals, which held a hearing on November 9, 1972, and issued its opinion on November 22, 1972. The opinion, prepared by Judge Compton and concurred in by Judges Roth and Fleming, reversed, with direction, the original judgment handed down by Judge Moor. In essence, the City of Los Angeles was given rights to all water in ULARA including the use of the underground basins. The defendants, however, were given the right to capture "return water," which is water purchased from the Metropolitan Water District of Southern California (MWD) that percolates into the basin.

A petition for rehearing was filed on December 7, 1972, but was denied by the Court of Appeals. On January 2, 1973, the defendants filed a petition for hearing with the State Supreme Court. The Court on March 2, 1973 advised the parties it would hear the case. The hearing was held on January 14, 1975.

On May 12, 1975, the California Supreme Court filed its opinion on the 20-year San Fernando Valley water litigation. This opinion, which became final on August 1, 1975, upheld the Pueblo Water Rights of the City of Los Angeles to all ground water in the San Fernando Basin derived from precipitation within ULARA. The City of Los Angeles' Pueblo Water Rights were not allowed to extend to the ground waters of the Sylmar and Verdugo Basins.

The City of Los Angeles was also given rights to all San Fernando Basin ground water derived from water imported by it from outside ULARA and either spread or delivered within ULARA. The Cities of Glendale and Burbank each were given rights to all San Fernando Basin ground water derived from water that each imports from outside ULARA and delivered within ULARA. San Fernando was not a member of MWD until the end of 1971, and had never prior thereto imported any water from outside ULARA.

The Supreme Court reversed the principal judgment of the Trial Court and remanded the case back to the Superior Court for further proceedings consistent with the Supreme Court's opinion. On remand the ~ase was assigned to the Honorable Harry L. Hupp, Judge of the Superior Court of Los Angeles County.

The Final Judgment, signed by the Honorable Harry L. Hupp, was entered on January 26, 1979. Copies of the Final Judgment are available from th ULARA Watermaster, Post Office Box 111, Room 1466, Los Angeles, California 90051. The water rights set forth in the judgment are consistent with the opinion of the Supreme Court described above. In addition, the Final Judgment includes provisions and stipulations regarding water rights, the calculation of imported return water credit, storage of water, stored water credit, and arrangements for a physical solution for certain parties as suggested by the Supreme Court.

On August 26, 1983, the Wastermaster reported to the Court pursuant to Section 10.2 of the Judgment that the Sylmar Basin was in a condition of overdraft. In response to the Watermaster's letter and a Minute Order of this Court, the Cities of Los Angeles and San Fernando responded by letters to the Court, agreeing with the Watermaster's report on overdraft. On March 22, 1984, Judge Harry L. Hupp signed a stipulation ordering, effective October 1, 1984, that the Cities of Los Angeles and San Fernando shall be limited in their pumping to bring the total pumping within the safe yield of the basin, less any rights exercised by the private parties.

Summary of 1985-86 Operating Conditions

Table 1 compares statistics for this period of record and the prior water year.

Rainfall on the valley fill area was 128 percent of normal as compared to 67 percent of normal the year before. Surface runoff leaving the valley at Gage F-57C-R for 1985-86 was 155,090 acre-feet. The amount conserved by the LACDPW in its spreading basins was 26,917 acre-feet, an increase of 58 percent over last year. Total precipitation falling on the San Fernando Valley and its tributary hill and mountain areas was estimated to be 628,086 acre-feet for the 1985-86 water year. Of this total, approximately 106,720 acre-feet flowed from the valley as storm runoff and rising water, leaving 521,366 acre-feet which was beneficially used within the area (83 percent of the total).

Ground water extractions decreased in the San Fernando and Sylmar Basins and increased in the Verdugo and Eagle Rock Basins during 1985-86. Total ULARA extractions amounted to 102,752 acre-feet as compared to an allowable pumping of 116,192 acre-feet. Of this total, 113,001 acre-feet represents the 1985-86 extraction rights of parties in the San Fernando Basin (see 1985-86 Table 15) plus the safe yield values of Sylmar and Verdugo Basins. The remaining 3,181 acre-feet is non-consumptive use pumping (see Table 13). Extractions used within ULARA decreased by 6 percent (1,541 acre-feet) from last year.

For ULARA, gross imports decreased by 2,145 acre-feet, or less than 1 percent, while imports used within ULARA increased less than 2 percent (5,123 acre-feet). Exports of Owens River water decreased by 7,268 acre-feet, or 2 percent. The total amount delivered to water users within ULARA increased by 3,727 acre-feet, or about 1 percent.

Sewage export was 153,131 acre-feet in 1985-86, an increase of 20 percent. Total reclaimed water used in ULARA (cooling towers, irrigation, etc.) increased 6 percent (145 acre-feet), while the total water reclaimed increased from 15,853 acre-feet to 44,350 acre-feet, an increase of 180 percent. Most of the reclaimed water is discharged to the Los Angeles River.

A total of 28,350 acre-feet of water, 26,917 native and 1,433 Owens River, was spread during the year, which was a 26 percent increase from last year in spreading of imported and native water.

Ground water storage for the San Fernando and Sylmar Basins decreased by 7,980 acre-feet and 120 acre-feet, respectively, and increased in the Verdugo Basin by 130 acre-feet during 1985-86.

II. WATER SUPPLY CONDITIONS

The present water supply of ULARA consists of ground water recharge from imported water, hill and mountain runoff, and direct precipitation on the valley floor area. This includes runoff from precipitation falling on portions of the San Gabriel, Verdugo, Santa Monica, and Santa Susana Mountains; imports from the Mono Basin-Owens River system; imports from the Colorado River; imports from Northern California made available by the State Water Project; and reclaimed water.

Precipitation

ULARA has the climate of an interior valley and is hotter in summer and wetter in the winter than the coastal areas.

Precipitation varies considerably throughout ULARA, depending on topography and elevation. Mean seasonal precipitation ranges from about 14 inches at the western end of the San Fernando valley to 35 inches in the San Gabriel Mountains. Approximately 80 percent of the annual rainfall occurs from December through March.

The 1985-86 water year experienced above average rainfall. The Valley floor received 20.27 inches of rain, whereas the mountains received approximately 24.54 inches. Tpe weighted average of both valley and mountain areas was 23.27 inches, an increase of 9.96 inches from last year. The 100-year (1881-1981) average precipitation for the valley and mountains is 16.48 inches and 21.91 inches, respectively. Table 3 presents a record of rainfall at 17 key precipitation stations which were used to develop the lOa-year average rainfall and are described in the Report of Referee.

In the safe yield evaluation, precipitation on the valley is determined separately from that on the hills and mountains. The valley is made up of the four ground water basins, whereas the hills and mountains comprise the remaining areas in ULARA. Precipitation in the hills and mountains is evaluated to relate the runoff from the watersheds of Big Tujunga, Pacoima Creek, and Sycamore Canyon to the runoff records which are included in this report and also to calculate the ground water recharge. See Plate 5 for location of precipitation stations.

Runoff and Outflow from ULARA

The drainage area of ULARA contains 328,500 acres, of which 205,700 acres are hills and mountains. The drainage system, in turn, is made up of the Los Angeles River and its tributaries. Surface flow originates as storm runoff from the hills and mountains; storm runoff from the impervious areas of the valley; operational spills of imported water; industrial and sanitary waste discharges; and rising water.

A number of stream-gaging stations are maintained throughout ULARA, either by LACDPW or United States Geological Survey (USGS). The Watermaster has selected six key gaging stations which, in effect, record runoff from hydrologic areas in ULARA.

Table 4 summarized the monthly runoff for these gaging stations and compares the 1984-85 water year with the 1985-86 year. The changes in runoff reflect the increase in rainfall in the valley and in the mountains.

Station F-57C-R registers all surface outflow from ULARA.

Station F-252-R registers flow from Verdugo Canyon plus flows from Dunsmore and Pickens Canyons.

Station E-285-R registers flow from the westerly slopes of the Verdugo Mountains and some flow east of Lankershim Boulevard. It also records any releases of reclaimed wastewater discharged by the City of Burbank.

Station F-300-R registers all flow east of Lankershim Boulevard plus outflow from Hansen Dam that is not spread. These records also include releases from Sepulveda Dam, which may include extractions from Reseda wells.

Station F-168-R registers all releases from Big Tujunga Dam, which collects runoff from Tujunga Canyon northeast of the dam. Runoff below this point flows to Hansen Dam.

Station 118B-R registers all releases from Pacoima Dam that originate in Pacoima Canyon. Runoff below this point flows to the Lopez and Pacoima spreading grounds and on down to the Los Angeles River through lined channels.

The locations of these key gaging stations are shown on Plate 5. The mean daily discharge rates for these six gaging stations during 1985-86 are summarized in Appendix B.

The Watermaster has computed the surface flow of the Los Angeles River at Gaging Station F-57C-R as to the sources, i.e. storm runoff from precipitation, Owens River water, rising water, and industrial and reclaimed wastewater discharges. The Watermaster utilized the procedures outlined in the Report of Referee for estimating the approximate flow rates and sources of water passing Gaging Station F-57C-R. A similar calculation was made for Station F-252-R. A summary of the procedures used follows, and a tabulation of the computed flows is shown in Table 5.

The base low flows were separated from the surface runoff by the use of the hydrographs of Station F-S7C-R. Base flows consist of rising water and industrial waste plus reclaimed water. Separation of base flow from surface runoff is based on the following assumptions:

Rising water equals base low flow minus the sum of industrial discharge water and reclaimed water. Industrial discharge waters are estimated from City of Los Angeles waste permits, Los Angeles-Glendale and Tillman reclamation plant discharges, and low flows in the Burbank-Western storm drain which include wastewater from the Burbank reclamation plant.

When the City of Los Angeles diverts water at the Headworks spreading grounds, most of the rising water is diverted.

When there is no diversion, a portion of the rising water may percolate upstream from Station F-S7C-R.

Historically, the surface runoff obtained from the hydrographs of Station F-S7C-R consisted primarily of storm runoff and Owens River water. The last releases of Owens River water into the Los Angeles River occurred in February 1971 due to the San Fernando earthquake. Releases in the future are expected to be minimal, but if they do occur, separation of surface runoff will be based on the following assumptions:

Net storm runoff equals surface runoff minus Owens River water.

If the Headworks diversion structure is used, all releases of Owens River waters are diverted to the Headworks spreading grounds. If the Headworks diversion structure does not divert water, all releases of Owens River waters are considered as passing Station F-S7C-R.

Ground Water Recharge

Local precipitation can have a marked influence on the ground water supply and water in storage. However, there is a wide variation in the annual amount of runoff as a result of changes in both precipitation and retentive characteristics of the watershed.

Urban development during the past years in ULARA has resulted in much of the rainfall being collected and routed into paved channels, which discharge into the Los Angeles River, and subsequently being carried out of the basin.

To somewhat overcome the increased runoff due to urbanization, Pacoima and Hansen Dams, originally built for flood protection,

I I I I I I I I I I I I I I I I I I I

I I I I I I I I I I I I I I I I I I I

were utilized to regulate storm flows to recapture the flow in downstream spreading basins operated by LACDPW, as well as the City of Los Angeles. Operation of Hansen Darn for the purpose of spreading water for recharge has become increasingly more difficult due to the sand and gravel that has accumulated within the forebay of the darn.

LACDPW operates the Branford, Hansen, Lopez, and Pacoima spreading grounds. The City of Los Angeles, in turn, operates the Tujunga and Headworks spreading grounds. Plate 2 shows the locations of these spreading basins. The spreading grounds operated by LACDPW are utilized for spreading native water and imported water under contract. The spreading grounds operated by the City of Los Angeles are utilized to spread OWens River and native waters, ground water, and the discharge from the Reseda wells. Table 6 summarized the spreading operations for the 1985-86 water year.

Ground Water Table Elevations

During the 1985-86 water year, the Watermaster collected and processed data to determine prevailing ground water conditions in ULARA during the spring and fall of 1986. Plates 7 and 8 show these conditions. Change in ground water surface elevation from fall of 1985 to fall of 1986 as presented in Plate 9 reflects the effects of variations in spreading, ground water extractions, and replenishment from rainfall. Plate 10 provides a di~gramrnatic sketch of the direction travel time for ground water flow in the San Fernando and Verdugo Basins in 1980.

Figures 1 and 2 depict water levels at key wells with their approximate locations indicated by numbers shown on Figure 2 map.

Water Reclamation

Water reclamation presently provides a source of water for irrigation, industrial and recreational uses, and ground water recharge which occurs in the unlined section of the Los Angeles River. Six wastewater reclamation plants are in operation in ULARA. A tabulation of operating water reclamation plants is shown on Table 7.

Water Quality

Water resources management must take into account water quality as well as water supply. The total dissolved solids (TDS) concentration in water is the quality indicator that is generally used. A comparison of the TDS content in the various water sources is shown in Figure 3. Representative mineral analyses of imported, surface, and ground waters for 1985-86 are contained in Table 8.

An Interagency Coordinating Committee has been formed to coordinate the implementation of the Groundwater Quality Management Plan -San Fernando Valley Basin - in order to deal with the organic contaminants TCE and PCE found in the groundwater •. Table 9 shows the total number of wells for 1985-86 exceeding the California DOHS action levels for these contaminants.

Imported Water

A.

B.

C.

Owens River-Mono Basin water is sodium bicarbonate in character and is the highest quality water available to ULARA. Its TDS concentration averaged about 210 milligrams per liter (mg/l) for 30 years before 1969, the highest record being 320 mg/l on April 1, 1946, and the lowest 150 mg/1 on September 17, 1941. Average TDS concentration for 1985-86 was 185 mg/1, which was 2 percent higher than the 165 mg/1 for 1984-85.

Colorado River water is predominantly sodium-calcium sulfate in character, changing to sodium sulfate after treatment to reduce total hardness. Samples taken at the Burbank turnout between 1941 and 1975 indicated a TDS concentration high of 875 mg/1 in August 1955 and a low of 625 mg/1 in April 1959. The average TDS over the 34-year period was approximately 740 mg/1. Tests conducted at Lake Matthews showed an average TDS of 522 mg/1 for 1985-86, a decrease of 10 percent from last year.

Northern California water (State Water Project water) is sodium bicarbonate-sulfate in character. It generally contains less TDS and is softer than local and Colorado River water. Since its arrival in Southern California in April 1972, the water had a high TDS concentration of 390 mg/1 and a low of 247 mg/1. Tests of Northern California water are taken at the Joseph Jensen Filtration Plant. Average TDS concentration during 1985-86 was 313 mg/l, an increase of 8 percent over last year.

D. Colorado River and Northern California water were first blended at the Weymouth Plant in May 1975. In the 1985-86 period, TDS had an average value of 367 mg/1 which was a 31 percent decrease from 1984-85. Blending rations vary at the Weymouth Plant and tests are taken from the effluent.

Surface Water

Surface runoff contains salts dissolved from rocks in the tributary areas. Surface water is sodium-calcium, sulfate­bicarbonate in character. In 1985-86, low flows in the Los Angeles River at Colorado Boulevard had an average TDS content of 668 mg/l and a total hardness of 295 mg/1, an increase and decrease over last year of 6 and 23 percent, respectively.

Ground Water

Ground water in ULARA is moderately hard to very hard. The character of groundwater from the major water-bearing formations is of two general types, each reflecting the composition of the surface runoff in the area. In the western part of ULARA, it is calcium sulfate-bicarbonate in character, while in the eastern part, including Sylmar and Verdugo Basins, it is calcium bicarbonate. TDS increased in the western part of the San Fernando Basin by 4 percent from 1982-83 to 1983-84~ increased by 2 percent in the eastern part over 1984-85~ increased by 2 percent in the Sylmar Basin from 1982-83~ and increased by 13 percent from 1981-82 to 1984-85 in the Verdugo Basin.

Groundwater is generally within the recommended limits of the United States Public Health Service Drinking Water Standards, except perhaps for wells in the western end of the San Fernando Basin having excess concentrations of sulfate and those in the lower part of the Verdugo Basin having abnormally high concentrations of nitrate.

Groundwater Quality Management Plan

During 1985-86, the Interagency Coordinating Committee (ICC) continued to implement the recommendations of the Groundwater Quality Management Plan - San Fernando Valley Basin (GWQMP) which are to protect the groundwater basin and to reduce concentrations of trichloroethylene (TCE) and tetrachloroethylene (PCE). There were seven active subcommittees operating during 1985-86 to implement the GWQMP recommendations. More than 20 state and local agencies are participating in the subcommittees. Several noteworthy accomplishments, described below, resulted from subcommittee activities.

Underground Tanks - The cities of Los Angeles and Glendale, and Los Angeles County have developed and are implementing guidelines to enforce ordinances to regulate underground storage tank construction and monitoring.

Private Sewage Disposal System -

The City of Los Angeles bureau of Sanitation is implementing the ordinance adopted in 1985, requiring the proper abandonment of Private Sewage Disposal Systems (PSDS) and connection to the public sewer system. A survey of the number of PSDSs that require abandonment was preformed. A total of 460 Notices to Connect to available sewers were issued to property owners.

As part of the above effort, the Bureau of Engineering is continuing work on 18 sewer construction projects in unsewered areas of the City. Once the sewer construction projects are completed, existing PSDSs can be abandoned, and commercial building waste-water discharges can be routed to the public sewer system.

27

Monitoring - Recent legislation, A.B. 3525 (1984), has required the State Water Resources Control Board (SWRCB) to conduct an evaluation of the impact of solid waste disposal sites upon air and water quality within the state. Under this program, a designated number of owners of disposal sites are required to prepare and submit Solid waste Assessment Test (SWAT) Reports indicating the extent of their impact of these sites upon the groundwater and air. The City of Los Angeles as owner of the Sheldon-Arleta, Toyon, Lopez, and Branford landfills must submit SWAT Reports for these facilities to the Regional Water Ouality Control Board in the 1987-89 period. DWP has assisted in the selection of the contractors to prepare these reports and has provided technical information. The DWP has provided water quality, Tujunga Spreading Grounds data, and water level information to assist the Los Angeles City Bureau of Sanitation in performing the SWAT.

Cities and agencies in the Upper Los Angeles River Area continued to monitor the volatile organic contamination in their production well fields. Table 9 shows the results of this monitoring and the scope of the contamination by summarizing the number of ULARA wells that are contaminated at various levels above the California State Department of Health Services action levels of 5 ppb for TCE and 4 ppb for PCE.

Water Treatment - The LADWP has proceeded with the development of the North Hollywood-Burbank Aeration Facility.

"The South Coast Air Quality Management District (AQMD) has approved the air quality permit application, and DWP is proceeding with the preconstruction phase of the project.

The DWP continues its research into the combined use of ultraviolet radiation and ozonization as possible alternative to other technologies for the removal of organic chemicals from groundwater sources. James M. Montgomery, Consulting Engineers, Inc., in cooperation with Dr. William Glaze of UCLA, is currently conducting this research under a cooperative agreement between DWP and the U.S. EPA.

The LADWP continues work on the well packer project in 14 North Hollywood wells. The purpose of this project is to seal off the contaminated upper aquifer zone from the lower zone and to pump clean water from the lower aquifer zone.

The well packer project involves: 1) the removal of the well pumps; b) photo-logging the well casings; c) re-installation of the well pumps; d) installation of the packer on the pump discharge column at the selected depth; and e) testing of the packer, both inflated and deflated, to determine the level of improvement in the quality of extracted water.

U.S. EPA Superfunding - As part of a program to remove the TCE and PCE from the ULARA groundwater basins, the LADWP filed an application with the U.S. EPA Superfund Program for the funding of a remedial investigation. Four sites, the North Hollywood, Crystal Springs, Pollock, and Verdugo areas, were officially designated as cleanup sites by the U.S. EPA and have been included on the National Priority List as the first step in the Superfund process. The next step in the process required a Remedial Investigation to determine the scope of the problem. In December 1985, DWP submitted a final application for funding of the Remedial Investigation to the U.S. EPA.

In order to expedite cleanup of a particularly important site, the U.S. EPA has approved a special DWP Fast Track Plan for the North Hollywood-Burbank site. This site will be administered separately from the other Superfund sites in the Upper Los Angeles River Area and will have the highest priority in the current program.

The U.S. EPA approved an advanced match of $300,000 in March 1986 for the North Hollywood-Burbank Aeration Facility.

Due to delays in u..S. EPA funding, the DWP Board of Commissioners authorized $2.5 million for a groundwater remediation program to proceed prior to the receipt of federal funds. The U.S. Congress authorized a $9 billion Superfund Program in October 1986. The U.S. EPA is seeking to obtain the necessary funding for the' San Fernando Valley Groundwater Quality Remedial Programs.

Leaking Underground Tank Investigations - During 1985-86, underground tank leak investigations with the potential for impacting ground water were active at four sites. The investigative sites, Centralab, Lockheed, Riker Lab-3M, and Rockwe11-Rocketdyne, are under the direction of the California Regional Water Quality Control Board. As part of the investigations, wells have been drilled and ground water has been extracted for the purpose of well development and testing. The following is the amount of water pumped by these non-parties during 1985-86:

The ULARA Administrative Committee approved on October 17, 1985 the extraction of ground water for testing and site investigations associated with potential ground water contamination. The above non-parties submitted estimates of anticipated pumping to the ULARA Watermaster and received approval. A stipulation allowing parties with no pumping rights to extract high-level TCE ground water for evaluation and cleanup is currently being drafted.

Other Activities - The DWP began construction of a new production well field in the Sun Valley area of the San Fernando Valley to provide a safe and adequate water supply to its customers. Rinaldi-Toluca Well Nos. 1 through 6 have been completed, and drilling of Rinaldi-Toluca Well Nos. 7 through 11 and construction of a collector line is scheduled for the upcoming year.

III. WATER USE AND DISPOSAL

Water delivered for use in ULARA is either imported water, local ground water, local surface diversions, reclaimed, or a mixture of local and imported water, depending on the area and water system operation. During the 1985-86 water year, the total amount delivered to water users in ULARA was 370,805 acre-feet. Of this total, 25,609 acre-feet was ground water, 342,559 acre­feet was imported, and 1,433 acre-feet was reclaimed water. Refer to Figure 5 for a monthly breakdown. The basin contains 542 wells, of which 132 are active and 410 are inactive, observation, test, capped, etc.

The original trial court adjudication of ground water rights in ULARA (no longer in effect) restricted all ground water extractions, effective October 1, 1968. On that date, extractions were restricted to approximately 104,000 acre-feet per water year. This amounted to a reduction of approximately 50,000 acre-feet below the previous six-year average. The State Supreme Court's opinion, as implemented on remand in the Final Judgment entered on January 26, 1979, provides a similar restriction in ground water pumping. Refer to the previous section entitled "History of Adjudication" for details of allowed pumping.

Spark letts Drinking Water Corporation and Deep Rock Water Company are the only parties that extract water from the Eagle Rock Basin.

Figure 4 illustrates the annual ground water extractions and total water imported in ULARA, beginning with the 1944-45 water year. Note the change from 1968-69 through the present.

It can also be noted that for 10 years before pumping was restricted, imports exceeded extractions from 50,000 to 90,000 acre-feet per year and that, for the water years 1968-69 to 1985-86, the difference has increased to between 110,000 and 260,000 acre-feet.

Figure 5 provides an analysis of the monthly relationship between rainfall, ground water extractions, and imported supply. Data relates to all ULARA and not to anyone specified ground water basin. The precipitation values were obtained from stations on the valley floor (Table 3).

Ground Water Extractions

Appendix A is the record of groundwater extractions for the 1985-86 water year, and Plate 6 shows the approximate location of the well fields which pumped this water. A total of 90,833 acre-feet was pumped from the .San Fernando Basin compared to an allowable pumping of 103,523 acre-feet. Of this total, 99,651 acre-feet is extraction rights by parties in the San Fernando Basin (see 1984-85 Table 15), with its remaining 3,872 acre-feet

being nonconsumptive use pumping (see Table 13). A total of 6,242 acre-feet was pumped from the Sylmar Basin and 5,493 acre­feet from the Verdugo Basin. The respective safe yield values for these three basins are 90,680, 6,210, and 7,150 acre-feet. Pumping in the Verdugo Basin is less than safe yield due to water quality problems. Construction of water blending facilities in the Verdugo Basin by the City of Glendale was completed in September 1981. This allows poorer quality Verdugo Basin ground water to be blended with MWD water and now enables Glendale to pump its prescriptive right in the Verdugo Basin.

Imports and Exports of Water

Residential, commercial, and industrial expansions in ULARA require the importation of additional water supplies to supplement that provided by the ground water basins.

The imported supplies to ULARA are from the City of Los Angeles' Owens-Mono Basin aqueduct and through the MWD distribution system, which consists of California and Colorado River Aqueduct waters.

Exports from ULARA, exclusive of sewage, are limited to the City of Los Angeles, which exports imported and ground water. Table 10 summarized the nontributary imports and exports from ULARA. Ground water imports and exports in and out of ULARA are listed in Table 12.

Physical Data by Basins

The Watermaster has collected and summarized data in Table 12 which show the water supply and disposal in each of the basins.

The information for Table 12 was submitted by the parties. In instances where estimates were made by the parties, such as water delivered to hill and mountain areas, sewage exported, etc., these were based upon methods consistent with previous estimates computed by SWRCB for the San Fernando Valley reference. The Watermaster also made computations of subsurface outflows based on similar computations made by SWRCB.

Pumping by private parties is summarized in Table 13.

San Fernando Basin Allowable Extractions

Table 14 lists San Fernando Basin extraction rights for the Cities of Burbank, Glendale, Los Angeles, and San Fernando for the water year 1986-87. Table 15 shows San Fernando Basin stored water as of October 1, 1985 and October 1, 1986. All rights are based on the City of Los Angeles vs. City of San Fernando, et al., judgment, dated January 26, 1979.

Sylmar Basin Allowable Extractions

Table 16 shows Sylmar Basin stored water as of October 1, 1985 October 1, 1986. All rights are based on the March 22, 1984 stipulation between the City of San Fernando and the City of Los Angeles and filed with the Superior Court.

Facts Relevant to Ground Water Storage Capacity*

San Fernando Basin. The total ground water storage capacity of San Fernando Basin is approximately 3,200,000 acre-feet, with a regulatory storage capacity of 350,000 acre-feet required by the judgment. As of 1954-55, the temporary surplus in the basin had been exhausted by the overextraction of approximately 520,000 acre-feet.

Sylmar Basin. Sylmar Basin consists of confined aquifers with ground water storage space of approximately 310,000 acre­feet.

Verdugo Basin. The ground water storage capacity of Verdugo Basin is approximately 160,000 acre-feet.

Change in Ground Water Storage

San Fernando Basin. The change in storage for 1985-86 was -7,980 acre-feet, and the cumulative change in storage from 1954-55 through 1985-86 was -186,780 acre-feet. A comparison is made between the annual precipitation and the cumulative change in storage since the commencement of watermaster activities for the San Fernando Basin. The average precipitation for the period 1968-69 through 1985-86 was 18.61 inches, compared to a long-term average of 16.48 inches of rainfall. During that time, the basin gained approximately 260,000 acre-feet of stored water. Of this total, 240,000 acre-feet was stored through spreading and in-lieu recharge activities. Thus, the natural change in storage due to an above normal rainfall period was 20,000 acre-feet. Refer to Table 11 for the annual precipitation and change in storage.

Sylmar Basin. The change in storage for 1985-86 was -120 acre-feet, and the cumulative change in storage from 1954-55 through 1985-86 was -23,300 acre-feet.

verdu¥o Basin. The change in storage for 1985-86 was +130 acre- eet, and the cumulative change in storage from 1954-55 through 1985-86 was +19,620 acre-feet.
