COUNCIL AGENDA REPORT ITEM NUMBER:
FROM: William T. Hetland Prepared By:Gary Henderson, Water Division Manager
Utilities Director Ron Munds, Water Conservation Coordinator
Sue Baasch, Administrative Analyst
SUBJECT: The 1992 - 1993 Water Operational Plan
CAO RECOMMENDATION:
By motion,
1. Receive and file report, providing direction to staff, as necessary; and
2. Approve reduction of City's Safe Annual Yield from 7,860 acre feet per year to
7,735 acre feet per year, which includes coordinated reservoir operations and
500 acre feet per year of groundwater.
REPORT IN BRIEF:
The City of San Luis Obispo experienced a near normal rainfall year this past year, which
resulted in a significant increase in storage at Salinas Reservoir, currently at approximately
96% of capacity. Whale Rock Reservoir has not responded as quickly and is currently at
approximately 44% of capacity. The increase in storage, a 78% increase in total storage
from the end of January to the end of February, allowed the City to exit mandatory
conservation on March 3, 1992. The City had been in varying levels of mandatory
conservation since April, 1989, a period of 36 months. Although the drought situation has
eased, another year of continuing drought conditions may require a return to Stage 1, 15%
mandatory conservation, in the spring of 1993.
The City's Reservoir Storage Curve is updated monthly with current storage information.
Figure 6 shows the storage curve updated with February storage information and revised
assumptions related to groundwater and action levels for conservation. The model uses very
conservative rainfall and inflow estimates based on 1989 information. Using these worst case
assumptions of the continuation of drought conditions, the model predicts the City's water
supply could reach minimum pool in late spring of 1996.
Staff revised the City's Safe Annual Yield computer model. The prior adopted safe annual
yield figure of 7,860 acre feet per year (afy) was based on a six year dry cycle which
occurred in 1946-51. The revised safe annual yield of 7,735 afy is now based on the 1986-
91 drought which is worse than the previous 1946-51 period.
FISCAL IMPACT:
The identified programs, if not currently reflected in the 1991/93 Financial Plan, will be
presented individually for Council consideration. No additional appropriation is required to
support these activities at this time.
CONCURRENCES:
The Community Development Department has reviewed and approved this plan.

1992-1993 WATER OPERATIONAL PLAN
I. INTRODUCTION
The first Water Operational Plan Policy Statement was adopted in 1985 as a means of
monitoring the City's water supply and reviewing current programs to address possible
diminishing supplies. This 1992 - 1993 annual report reviews current and projected reservoir
storage situations both from the viewpoint of continuation of the drought and.from strategic
programming to promote long-term water use efficiency. While the spring rans and runoff
brought temporary relief to the water situation, it is important to remember that the drought
may continue and, even if rainfall returns to pre-drought levels, indoor and outdoor water use
efficiency will continue to be a high priority for the City.

Reservoir storage is augmented by groundwater. At this time, approximately half of the water
used within the City each month comes from wells. It is expected that this level of production
may decline as the groundwater basin is lowered. As is shown in Figure 2, groundwater
production has averaged about 1,950 feet in each of the year's of full production.

Water Consumption and Conservation
The City of San Luis Obispo has been outstanding in its efforts to cut water consumption.
Figure 3 on the next page illustrates the level of conservation in the community since the
program began. in 1988. Using consumption levels from 1987 as the base for comparison,
staff estimates that approximately 11,000 acre feet have been saved due to the community's
excellent conservation efforts.
The increase in storage due to February rains and inflow allowed the community to leave
mandatory conservation on March 3, 1992. Historically, during mandatory conservation the
community exceeded the mandated level by at least 10%. Following the relaxing of 35%
mandatory conservation last April to 15% mandatory conservation, the community continued
to conserve at 26 to 54% below 1987 levels. Figure 4 shows what our history has been over
the last year regarding water conservation.
Staff feels there are at least two reasons for the high level of conservation. Consumers are
still taking a very cautious approach to increasing water use and realize the drought is not
over. Secondly, it appears that conservative water use habits have been adopted by most of
the community. The retrofitting of toilets, shower beads, and more efficient irrigation
systems have increased water efficiency and will continue to conserve water, even after the
drought is over. The City is currently using about 400 acre feet per month (Figure 4).
What will be the level of consumption now that the community has left mandatory
conservation? That is the question that all water agencies who have recently left mandatory
conservation are asking. Some level of permanent conservation is expected, but a return to
pre-drought levels of consumption are expected to occur, probably over a period of years.

111. MULTI-SOURCE WATER SUPPLY PROJECTS
In November, 1990, the Council adopted a multi-source water supply policy. This policy
stated that the City would not rely on a single source of water to meet its permanent water
needs. At that time, staff also identified a supplemental water requirement of 6,540 AF to
serve the full build-out capacity of the City as represented in the General Plan and create a
water supply contingency. To this end, numerous short and long-term water supply projects
are under development at this time. The following is a status report on each of these
projects:
Salinas Reservoir Expansion
The initial feasibility study including seismic analysis and initial environmental review have
been completed. This work showed that the project was technically feasible, cost effective i
and environmentally sound. Staff has met with the staff of north county communities to
discuss the project and review concerns those communities may have. Formal public
presentations to the various north county councils and boards have been completed. Council
recently authorized the contract with Woodward/Clyde Consultants for the preparation of the
environmental impact report (EIR).
The draft EIR is scheduled to be completed by December 1992, with Council certification of
the final EIR in March 1993. The design and permitting phase is estimated to require a
year to complete. Construction is estimated to begin in the summer of 1994 with
completion of the project in the summer of 1995.
State Water Project
Much activity occurred in the State Water Project this past year. An advisory election was
held in San Luis Obispo in April, 1991, and the vote was of 52% (4,198 votes) to 4717o
(3,716 votes) in opposition to the project. Elections in Santa Barbara County resulted in a
number of communities choosing to join the State Water Project. This will result in the
State Water Project proceeding with design and construction. The Final Environmental
Impact Report for the Local Projects was recently completed. The County has stated that
San Luis Obispo City Council must make a formal determination on participation in the
State Water Project by May 1, 1992.
Nacimiento Diversion Project
The City of San Luis Obispo investigated the possibility of developing a Nacimiento water
supply project. This project became more attractive after the April advisory election on the
State Water Project indicated a citizen preference that the project not be approved. The
Nacimiento project is technically feasible for the City to pursue alone, but the City realized
the significant regional concerns and requested that San Luis Obispo County be the lead
agency and begin development of a regional project.
The County is currently in the process of initiating a contract with Boyle Engineering
Corporation to provide a feasibility study of the project The contract is divided into three
phases. The first phase will be a reliability assessment of the safe annual yield of the
reservoir which is expected to be done in May of 1992. The second phase will address
agency allotments, alternative project designs, and geotechnical studies. The second phase is

scheduled to be completed .eight months after the notice to proceed is issued by the County.
Phase three will involve the preparation of a final report which is to be completed within 10
weeks of the notice to proceed is issued for this phase. The above timeframes will result in
completion of all phase in the spring of 1993.
Groundwater Wells i
The current groundwater program utilizes seven municipal wells and two or more irrigation
wells. At this time, wells are producing approximately 160 acre-feet (af) per month which
represents about 45% of the total City water demand. Prior to this years rains, the wells
showed declines in pumping water elevation. After the February rains, the groundwater
levels rose to the levels that were encountered at the start of the City's Groundwater
Development Program in 1989. The City will continue to use well water as a key element
of our water resources.
Wastewater Reclamation
Reclaimed or recycled water is intended to be a long-term water source for the City. The
current quality of the effluent from the City's Wastewater Treatment Plant (WWTP) meets
secondary treatment standards. The $35 million WWTP upgrade that is underway will
improve the effluent quality to an advanced level, so that a full water reclamation program
can be implemented. At this advanced level of treatment, the reclaimed water can be used
for park and playground irrigation, landscape or recreational impoundments, industrial
applications, construction use and other beneficial non-potable uses. i
By using treated wastewater effluent for non-potable water demand such as landscape
irrigation, the City's potable water will be made available for uses that require a higher
quality of water. Staff has estimated that reclaimed water could offset 800 to 1200 acre feet
per year of existing potable water demand by existing non-potable uses.
The water reclamation program is in the conceptual phase of its development. In this phase
market research is being performed, regulations are being researched and a feasibility study
is being performed. This phase of the water reclamation program is due to be completed by
mid-1992-
Before reclaimed water can be delivered to customers, the following must be accomplished:
prepare and certify the environmental documents; prepare an engineering report and its
submittal to the Department of Health Services (DHS) and the Regional Water Quality
Control Board; establish user contracts; establish revenue program; perform a detailed design
of storage, pumping and distribution facilities; and construction of those facilities. Staff has
estimated that reclaimed water to meet the DHS requirements for unrestricted public contact
will be delivered to the first customers in late 1994.
Cloud Seeding
In January, 1991, the City Council approved an agreement with Atmospherics Incorporated
of Fresno, California to provide a three-year cloud seeding program. The program "target
areas" are the Salinas reservoir and Lopez Lake watersheds. The County of San Luis
Obispo participated in the project and agreed to pay 37.8% of the total costs. During this
years operational period which started November 1, 1991, seventeen airborne seeding flights

V. PROJECTED WATER SUPPLY SITUATION
Reservoir Storage Curve
The Reservoir Storage Curve is integral to the City's Annual Water Plan analysis. It is a
model to estimate the City's reservoir storage based on historical water use, reservoir data
and available groundwater supplies. The model is used to forecast the City's water supply
position and to make. certain water policy recommendations. The curve has been updated to
reflect the City's current storage.
i
The model predicts current water storage to last until the late spring of 1996, under a set of
worst case conditions. Total storage is approximately at the same level that the City was in
early 1987, but the storage at Salinas reservoir accounts for a much higher percentage of the
total current storage than was the case in 1987. This is significant as evaporation affects
Salinas storage more dramatically, impacting the steepness of the projected storage curve.
If drought conditions return next winter, the curve predicts that the City may again enter
mandatory conservation in April, 1993. However, a return to normal rainfall patterns next
year would increase reservoir storage, especially at Whale Rock. This would continue to
pull the City out of the drought and would decrease the necessity of again implementing
mandatory water conservation program. i
The current increase in reservoir storage does n= influence the City's safe annual yield.

SUMMARY
As is indicated by the storage-curve, the City is still in a very guarded situation in regards to
available water supply. In the worst case scenario of continued drought conditions, the City
could be back into mandatory water conservation at the beginning of next year. It will take the
voluntary cooperation of our water customers and the next year's rainy season to eliminate the
need for a mandatory program. It is evident from the curve that the City needs to continue an
aggressive water conservation program to extend and maximize existing water supplies. Since
no new water supply projects will be completed in the near future, it is possible, lacking
adequate rainfall, that the City will be faced with the prospect of water rationing for several
years.
I
SAFE ANNUAL YIELD
The safe annual yield of the City's water supply sources is a critical component of water
management and is used to determine if adequate water supplies are available for present and
future residents. The operation of the City's current water supply system is simulated over the
historical period to determine the maximum level of demand or safe annual yield which could
be met during the most severe drought period for which records are available. The safe annual
yield is the amount of water that can be counted on for supply and can be a constraint to
future growth (ie building permits) if supplies are not adequate.
The "safe annual yield" of an individual source of water supply is defined as the quantity of
water which can be withdrawn each and every year under critical drought conditions and not
run out of water or have to implement mandatory water rationing. Safe annual yield analyses
of water supply sources are based on the hydrologic conditions (ie. rainfall, evaporation, and
stream inflow) experienced during a certain historical period. The period used in the analysis
begins in 1943 and is considered appropriate for safe annual yield estimates since the period
covers several extreme drought periods, including 1946-51, 1959-61, 1976-77, and 1986-91. The
historical period used in the latest computer analysis to determine safe annual yield has been
from 1941 through 1991, which includes the recent drought period. Although future hydrologic I
conditions will obviously not occur in the precise sequence and magnitudes as have occurred
historically, this technique provides an estimate of the future water supply capability of the
existing sources if the long-term historical record is considered representative of future
conditions.
Previous Safe Annual Yield Studies
Previous studies of the critical historical drought.periods at Salinas and Whale Rock Reservoirs
had indicated the following safe annual yields were available to the City of San Luis Obispo:

TOTAL 7,860 afy
' City's share of Whale Rock safe annual yield
The safe annual yield analysis for the two reservoirs assumed independent operation and
historical data to the date of each report. The critical drought period for these previous studies
was 1946-51. The studies also assumed a minimum pool at Salinas and Whale Rock of 400 and
500 of respectively. Coordinated operations is a concerted effort to operate the two reservoirs
together for maximum yield. Since Salinas Reservoir spills more often than Whale Rock
Reservoir (ie larger drainage area and runoff characteristics) and also has higher evaporation
rates, the combined yield from the two reservoirs can be increased by first using Salinas to
meet the City's demand and using Whale Rock as a back-up during periods when Salinas is
below minimum pool or unable to meet all of the demand. This was a preliminary
conservative estimate of the additional safe annual yield which could be obtained under
coordinated operation of the two reservoirs.
In December of 1988, the City authorized a contract with the engineering firm of Leesdhill-
Herkenhoff, Inc. to prepare a detailed analysis of the City's water supplies and an evaluation of
the safe annual yield based on coordinated operation of the reservoirs. The report titled
"Coordinated Operations Study for Salinas and Whale Rock Reservoirs" was completed in
February 1989. The study used hydrologic data from 1941 to 1988 to evaluate the safe annual
yield. The study evaluated a number of minimum pool amounts at each reservoir and the
impacts of these assumptions on the yield. From this study, assuming coordinated operation,
2,000 of of minimum pool at each reservoir, and 500 afy of groundwater per year, the City's
total safe annual yield was estimated to be09, 80 af. Since the City was in a drought period,
this amount of safe annual yield was never adopted by Council for planning purposes. It
should be reemphasized that this estimate assumed that Whale Rock Reservoir is only used
when Salinas is below minimum. pool or can not meet the monthly City demand due to
conveyance system limitations and does not consider limitations on the use of Salinas water due I
to water quality constraints.
Revised Analysis
The computer model developed to determine safe annual yield uses only four items of actual
historical data. The four items are rainfall, evaporation rates, inflow amounts at each reservoir,
and 'five stream" releases. To determine the safe annual yield, the computer operator inputs a
value for safe annual yield and the model calculates whether the reservoirs can meet this
demand without going below minimum pool. During this iterative process, the program reveals
that certain historical periods of time are critical in the determination of safe annual yield (ie
reservoirs reach minimum pool). Prior to the recent drought this "controlling period" was from
1946 to 1951. After updating the model to account for the recent drought period, the
controlling period is now 1986-1991 for the determination of the City's safe annual yield. A
revised estimate of the City's safe annual yield has been performed utilizing data from this
controlling period. The City's total safe annual yield from Salinas and Whale Rock Reservoirs,
including 500 acre-feet (AF) of groundwater per year, has been estimated to be 7.735 AF The

computer model includes hydrologic information from 1941 to 1991 and uses the following
assumptions:
■ Minimum pool at each reservoir is 2,000 acre-feet.
■ 1,000 acre-feet per year is used from Whale Rock to account for periods of water
quality problems at Salinas Reservoir (ie. turbid water conditions following storms, etc.).
■ 500 acre-feet per year of groundwater is used as a base flow.
■ Both reservoirs are assumed full at the beginning of the analysis period. Per the
Leedshill report, "Following a series of three consecutive wet years from 1941 to 1943,
water supply reservoirs can be assumed to be full regardless of the scenario being
analyzed.
■ Full estimated storage capacity is available (ie future siltation not accounted for).
■ "Live stream" release rates were estimated using statistical analysis and input for the
entire time period to account for the fact that this policy has only been in affect since
1972.
I
The computer model, with this updated information, now predicts that the City's total safe
annual yield is 7.735 acre-feet. As stated previously, the critical period for the calculations is
1986 to 1991. The analysis indicates that if the City water demand was constant each year
(7,735 ay) since 1941, Salinas Reservoir would have reached minimum pool in June of 1989
and the City's share of Whale Rock Reservoir would have been 499 of on March 1, 1991. This
indicates that if the "Miracle March Rains" had not happened, the City would have run out of
water in March of 1991 considering the assumptions listed above.
RECOMMENDATION
Adopt new City policy reducing the combined safe annual yield by 125 afy, from 7,860 afy to
7,735 afy, utilizing coordinated reservoir operations and 500 of per year of groundwater.
