AGENDA REPORT
Meeting Date: September 28, 2015
To: Citizens Advisory Committee
From: Marc Marcantonio, General
Manager
Prepared By: Damon Micalizzi, Public
Information Manager
Subject: Update on Conservation Efforts and Monthly Water Supply Report
SUMMARY:
Since the State Mandates began June 1, 2015 Yorba Linda Water District Customers have cut
consumption by 38% in June, 43% in July and 41% in August. Initial September data is trending in
a similar fashion. Exceeding the mandated 36% in these warmer months is crucial as it will be
harder to achieve 36% conservation in the fall and winter months when consumption is typically
lower.
Attached is the Metropolitan Water District of Southern California's September Water Supply Report

DATE: September 11, 2015
TO: Member Agencies — MWDOC Division One
FROM: Brett R. Barbre, Director— Division One
SUBJECT: Monthly Water Usage Data, Tier 2 Projection & Water Supply Information
The attached figures show the recent trend of water consumption in Orange County (OC),
an estimate of Tier 2 volume for MWDOC, and selected water supply information.
Fig. 1 OC Water Usage, Monthly by Supply OCWD Groundwater water was the
main supply in July.
Fig. 2 OC Water Usage, Monthly, Comparison to Previous Years Water usage in
July 2015 was well below average compared to past usage. Lower usage is
primarily due to unusual rainfall for July produced by the remnants of
Hurricane Delores and strong conservation and mandatory restrictions set by
the governor.
Fig. 3 Historical OC Water Consumption OC water consumption was 571,000 AF in
FY 2014-15. This is about 50,000 AF less than FY 2013-14 but is about
16,000 AF higher than FY 2010-11 (Fiscal year with lowest usage). Water
usage per person was the lowest it has been for Orange County at 164
gallons per day. Although OC population has increased 20% over the past
two decades, water usage has not increased, on average. A long-term
decrease in per-capita water usage is attributed mostly to Water Use
Efficiency (water conservation) efforts. High Temperature, precipitation and
the economy all remain indicators to O.C. water consumption.
Fig. 4 MWDOC "Firm" Water Purchases, 2015 "Firm" water above the Tier 1 limit
will be charged at the higher Tier 2 rate. Our current projection of Tier 2
purchases is zero in 2015.
Water Supply Information Includes data on: Rainfall in OC; the OCWD Basin overdraft.,
Northern California and Colorado River Basin hydrologic data-, the State Water Project
(SWP) Allocation, and regional storage volumes. The data has implications for the
magnitude of supplies from the three watersheds that are the principal sources of water for
t"
OC. Note that a hydrologic year is Oct. 1 st through Sept. 30 .
• Orange County's accumulated rainfall through August was below average for this
period. This continues the impact of the previous three hydrologic years' below-
normal rainfall in reducing those local supplies that are derived from local runoff. In
July the Southern California area did receives significant measurable rainfall due to
the remnants of Hurricane Dolores. Santa Ana received about a half inch of rain
which is extremely rare for July. NOAA is predicted that there is a 90% chance of El
Nino conditions for this winter and 85% chance of El Nino next spring.
• Northern California accumulated precipitation in July was around 75% of normal for
this period. The Northern California snowpack was 5% of normal as of April 1St, the
date used for year-to-year comparison. This follows three below-average hydrologic
years. The State of California has been in a declared Drought Emergency since
January 2014. The State Water Project Contractors Table A Allocation is only 20%
as of the end of July.
• Colorado River Basin accumulated precipitation in August was 94% average for this
period. The Upper Colorado Basin snowpack was 64% of average as of April 15t"
However, this follows two below-average hydrologic years, and this watershed is in a
long-term drought. Lake Mead and Lake Powell combined have about 59% of their
average storage volume for this time of year. Lake Mead is the largest reservoir in
the United States and as of now the Lake is at its lowest levels since filling in the late
1930's. If Lake Mead's level falls below a "trigger" limit at the end of a calendar
year, then a shortage will be declared by the US Bureau of Reclamation (USBR),
impacting Colorado River water deliveries for the Lower Basin states. As of Late July
Lake Mead Levels were hovering around the "trigger" limit but fortunately levels are
expecting to increase from the large amounts of precipitation that hit the Colorado
River Basin this summer and spring. The USBR predicts that the "trigger" level will
not be hit by the end of 2015.

Notes
1. "Firm"includes Full Service(both Treated and Untreated)and Barrier water.
2. Basin Pumping Percentage(BPP)is the percentage of a retail water agency's total water demand that they are limited to pump from the OCWD-managed groundwater basin. BPP pertains to Basin agencies only. For
example,if a Basin agency's total demand is 10,000 AF/yr and OCWD sets the BPP at 72%,then the agency is limited to 7,200 AF of groundwater that year. There may be certain exceptions and/or adjustments to that
simple calculation. OCWD sets the BPP for the Basin agencies,usually as of July 1st. Import demands for Jan.-Jun.were with BPP of 72%for Basin agencies; for Jul.-Dec.they are projected with BPP of 70%.
