ITEM NO. 4.2 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 ATTACHMENTS: Description: Type: Water Supply Report- BB.pdf September Water Supply Report MWD Backup Material MLJNICIRAL WATER DISTRICT OF ORANGE --- -- --- COUNTY Memorandum 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.
