MEMORANDUM
TO: CITY COUNCIL
FROM: BILL ROBESON. PUBLIC WORKS DIRECTOR
BY: SHANE TAYLOR, UTILITIES MANAGER
SUBJECT: MONTHLY WATER SUPPLY AND DEMAND UPDATE AND
PRESENTATION
DATE: FEBRUARY 27, 2018
SUMMARY OF ACTION:
The update reports the water supply and demand for January 2018. Current Lopez
Reservoir level and projected levels are provided in the attachments.
IMPACT ON FINANCIAL AND PERSONNEL RESOURCES:
Approximately two (2) hours of staff time is required to prepare the report.
RECOMMENDATION:
It is recommended the City Council receive a presentation and file the Monthly Water
Supply and Demand Report.
BACKGROUND:
On April 25, 2017, the City Council, by resolution, rescinded the Stage 1 Water
Shortage Emergency and related water conservation measures and restrictions. During
the public hearing, the City Council requested staff to continue preparing the monthly
water supply and demand updates. The Council also urged citizens to remain
cognizant of how they use water, and stated that the previously adopted water saving
measures are still in effect.
In January 2018, the City’s water use was 12% below 2013. The State’s previously
mandated water use reduction was based on the 2013 water usage. There is currently
no required reduction imposed by the State Water Resources Control Board. The City
however, is still required to report monthly statistics to the State. As a comparison for
the recent month, water usage was 27% higher in 2018 than 2017. The Per Capita use
was 91 gallons per day per person.
ANALYSIS OF ISSUES:
The United States Department of Agriculture (USDA) Drought Monitor, as of February 6,
2018, shows San Luis Obispo County in a moderate to severe drought. Rain fall to date

(July 1, 2017 to February 14, 2018) is 3.1 inches at the Corporation Yard gauge. Lopez
Lake, as of February 14, 2018, is at 50.5% capacity (24,953 acre-feet of storage).
At the County of San Luis Obispo Board of Supervisors meeting on May 23, 2017, the
Board rescinded the drought emergency proclamation. However, as recommended by
Zone 3 Advisory Board, the Board of Supervisors kept the Low Reservoir Response
Plan in place. This will allow carryover water to be available until March 30, 2018 to all
contractors. The new water year began on April 1, 2017 and the current total available
supply from Lopez is 2,290 acre-feet, our normal entitlement, plus 1,249 acre-feet of
carryover. In addition, we have 1,323 acre-feet of ground water entitlement from the
Santa Maria Basin and 200 acre-feet from the Pismo Formation.
Based on the projected water use of 2,500 acre-feet, we will meet the demand in water
year 2017/18, using only 50% of current supply.
