California Water Condition Updates
Media Briefing packet for scheduled announcement 2/20/09 on WY 2009 CVP Water Supply Allocation
Given this winter’s dry conditions and resulting low reservoir storages, Central Valley Project (CVP) operations and water delivery in Water Year (WY) 2009 will be very challenging. The Bureau of Reclamation made the first official 2009 CVP water allocation announcement on February 20, 2009.
Water conditions over the past several years have been dry. WY 2007 and WY 2008 were critically dry for both the Sacramento and San Joaquin River Basins. Precipitation in Northern California in WY 2008 was about 70 percent of average, and the CVP carried over only 3.9 million acre-feet (MAF) from WY 2008 into WY 2009, just 35 percent of storage capacity (Reclamation’s WY runs from October 1 to September 30). Carry over from WY 2007 to WY 2008 was 5.3 MAF. The 2-year combined total Northern California precipitation for WY 2007 (37.2 inches) and 2008 (34.9 inches) is 72.1 inches, the 9th driest 2-year period on record and only about 70 percent of average.
The Bureau of Reclamation is comparing the current storage of certain CVP reservoirs with the storage on the same day in 2008 and 2007, 1992 and 1977 (drought years), and the 15-year average.
