TO: CITY COUNCIL
FROM: BILL ROBESON, PUBLIC WORKS DIRECTOR
BY: SHANE TAYLOR, UTILITIES MANAGER
SUBJECT: MONTHLY WATER SUPPLY AND DEMAND UPDATE
DATE: MARCH 24, 2020
SUMMARY OF ACTION:
The update reports the water supply and demand for February 2020. 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 and file the monthly Water Supply and
Demand Report.
BAC KGROUND:
On April 25, 2017, the City Council, by resolution, rescinded the Stage 1 Water Shortage
Emergency along with related emergency 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 urged citizens to continue to
practice every day water saving measures, and reiterated that the previously adopted
water saving measures were to remain in effect.
In February 2020, the City’s water use was 177.4 acre-feet with a per capita use of 113
gallons per day/per person. There was a total of 0.0” of rainfall in February 2020. The
water use for the current “rolling” water year from March 2019 to February 2020 was 2,213
acre-feet, which equates to a per capita use of 112 gallons per day/per person. There
was a total of 12.2” of rain fall for this period.
ANALYSIS OF ISSUES:
The United States Drought Monitor, as of March 11, 2020 shows San Luis Obispo County
in an abnormally dry condition. Rainfall to date (July 1, 2019 to February 29, 2020) is 7.1
inches at the Corporation Yard rain gauge. Lopez Lake, as of March 11, 2020 is at 51.0%
capacity (25,206 acre-feet of storage).

MONTHLY WATER SUPPLY AND DEMAND UPDATE
MARCH 24, 2020

The new water year began on April 1, 2019 and the current total available supply from
Lopez is 2,290 acre-feet, our normal entitlement. 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. The projected water use for 2019/20 is 2,200 acre-feet. In conclusion, based
on average rainfall for the next two years, the current supply will meet the projected
demand.
