Cumulative Precipitation to Date: The accumulated six-station precipitation index for water year 2014 is 18.2 inches, which is 51.1% of the average annual water year total, or 55.7% of the average annual-to-date. Hetch Hetchy received 2.85 inches of precipitation in April, for a water year total of 19.6 inches. The cumulative Hetch Hetchy precipitation is shown in Figure 3 in red.

The index is computed as the average of the six stations and is expressed in inches and in percent. 3

The instream release schedule at Hetch Hetchy Reservoir for the month of April was Year Type C (dry conditions). This year type is based upon accumulated precipitation and runoff in water year 2014, starting October 1 st, The instream release requirement from Hetch Hetchy Reservoir for the month of April was 35 cfs. As of May 1 st, 2014, the water year type is B, under which 80 cfs is required below Hetch Hetchy Reservoir during May. A power draft of 33,802 acre-feet was made from Cherry Reservoir during the month of April to manage forecasted inflow and reservoir conditions. A total of 12,682 acre feet of water was transferred from Lake Eleanor to Cherry Reservoir during the month of April. The required minimum release for the month of April at Cherry Reservoir was 5 cfs, and was 20 cfs at Lake Eleanor. Local System Treatment Plant Production The Harry Tracy Water Treatment Plant average production rate for the month of April was 20 MGD. The Sunol Valley Water Treatment Plant was in standby mode for the month with no water production into the regional transmission system. Local System Water Delivery The April delivery rate was 197 MGD which is a 5% increase over the March delivery rate of 187 MGD. 4
5 Local Precipitation Rainfall totals for the month exceeded the monthly average totals. Year-to-date rainfall totals remain below average. The April rainfall summary is presented in Table 3. Reservoir Table 3 Precipitation Totals at Three Local Area Reservoirs for April 2014 Percentage of Water Year Month Total Average for the to Date 7 (inches) Month (inches) Percentage of Average for the Year-to-Date 7 Pilarcitos % % Lower Crystal Springs % % Calaveras % % 7 WY 2014: Oct through Sep Figure 4: Water Year conditions for the Tuolumne River at La Grange and for the 80% water supply forecast range (triangles represent the 90% and 10% forecasts, the open diamond represents the median forecast). Snowmelt and Water Supply Warm temperatures throughout the month of April brought on snowmelt in the high country. However, a storm event during the last week in April added 1.25 to 2.0 inches of additional snow water equivalent. The late month event brought with it low snowlines. The May 1 st snow surveys indicate the snowpack is near 22% for conditions at the time. While well below normal conditions exist, conditions in the Tuolumne Basin are much better than other watersheds in the Sierra. The Tuolumne Basin Water Supply Forecast model was executed using the measured snow course, precipitation, and runoff data. The forecast indicates that the median amount of runoff that may occur this year is about 43% of the long-term median (Figure 4). The median forecast of April-through-July runoff is about 465 TAF, compared to 5
6 the long-term median runoff for the April-through-July period of 1,080 TAF. For natural flow at La Grange, there is an 80 percent chance that the April-to-July natural runoff will be between 365 TAF and 600 TAF. As a result of the shallow snowpack and limited precipitation, water available to the City is well below the normal volume. At this time 18,890 acre-feet has been available this water year (Figure 5). Figure 5: Calculated unimpaired flow at La Grange and the allocation of flows between the Districts and the City. 18,890 acre-feet of water has become available to the City during water year 2014 to date. cc HHWP Records Gibson, Bill Levin, Ellen Rydstrom, Todd Briggs, David Graham, Chris Mazurkiewicz, Adam Sandkulla, Nicole Carlin, Michael Hale, Barbara Meier, Steve Tsang, Michael Chester, John Hannaford, Margaret Moses, Matt Williams, Mike DeGraca, Andrew Kelly, Harlan Patterson, Mike Sandkulla, Nicole Dhakal, Amod Jue, Tyrone Nelson, Chris Dufour, Alexis Kehoe, Paula Ramirez, Tim Gambon, Paul Lehr, Dan Ritchie, Steve 6
