percent of the April 1 average. The numbers for the southern Sierra are 48 percent of average for the date and 15 percent of the April 1 average. DWR and cooperating agencies conduct manual snow surveys around the first of the month from January to May. The manual measurements supplement and check the accuracy of real-time electronic readings. Results of today's manual readings by DWR off Highway 50 near Echo summit are as follows: %of Long Term Location Elevation Snow Depth Water Content Average Alpha 7,600 feet _inches _inches Not Yet Available Phillips Station 6,800 feet 21.3 inches 4 inches 33 Lyons Creek 6,700 feet _inches _inches Not Yet Available Tamarack Flat 6,500 feet inches inches Not Yet Available Historic Comparison The average January 1 snowpack water content at Phillips Station is about 12 inches; the April 1 average 27.6 inches. Phillips had its lowest early-January water content reading of 0.1 inch in 2012, in a snow depth of only 0.6 inches. On January 3, 2014, Phillips had 2.3 inches of water content in 9.3 inches of snow. Besides that reading and the similar one in 2012, the driest January readings at Phillips were in 1987 (0.9 inches of snowpack water content), 1981 (2 inches), 1976 (2.7 inches) and 2000 (3 inches). Records at Phillips go back 50 years. DWR currently estimates it will be able to deliver only 10 percent of the slightly more than 4 million acre- feet of State Water Project (SWP) water requested for calendar year 2015 by the 29 public agencies that collectively supply more than 25 million Californians and nearly a million acres of irrigated farmland. It is hoped the initial 10 percent delivery estimate will increase as winter storms develop. The final SWP allocation for calendar year 2014 was 5 percent of the slightly more than 4 million acre- feet requested. In 2013, it was 35 percent, and in 2012, the final allocation was 65 percent. It was 80 percent in 2011, up dramatically from an initial allocation of 25 percent. The final allocation was 50 percent in 2010, 40 percent in 2009, 35 percent in 2008, and 60 percent in 2007. The last 100-percent allocation —difficult to achieve even in wet years because of Delta pumping restrictions to protect threatened and endangered fish —was in 2006. DWR weather watchers note that it's early in the season with plenty of time for the snowpack to build. The concern, however, is that irrigation-dependent San Joaquin Valley farms and some other areas will be hard hit if Water Year 2015 ends as the fourth full year of drought. Storage in key reservoirs has increased due to heavy December rainfall but is still far below normal levels for the date. Lake Oroville in Butte County, the State Water Project's (SWP) principal reservoir, today is at only38 percent of its 3.5 million acre-foot capacity (61 percent of its historical average for the date). Shasta Lake north of Redding, California's and the federal Central Valley Project's (CVP) largest reservoir, is at 41 percent of its 4.5 million acre-feet capacity (66 percent of average for the date). San Luis Reservoir, a critical south-of-Delta reservoir for both the State Water Project and Central Valley Project, is a mere 39 percent of its 2 million acre-foot capacity (58 percent of average for the date) due both to dry weather and Delta pumping restrictions to protect salmon and Delta smelt. Delta water is pumped into the off- stream reservoir in winter and early spring for summer use in the Bay Area, San Joaquin Valley, Central Coast and Southern California. Continuing dry weather prompted Director Cowin on December 13, 2013 to mobilize DWR's drought management team "to offset potentially devastating impacts to citizen health, well-being and our economy."
