DWR Director Mark Cowin said:
Stubbornly dry conditions this winter give us no choice but to roll back our water supply estimate. We continue to hope, however, that wetter conditions in the remaining winter weeks will allow us to boost deliveries back up.Reclamation's Mid-Pacific Regional Director Donald Glaser added:
Hydrologically, 2012 is shaping up to be a challenging year. December – traditionally one of our wettest months – ended up being one of the driest on record and this pattern continues today. The good news is that we started the water year with exceptional carryover storage – 9.3 million acre-feet – and storage in our reservoirs now stands at 103 percent of the 15-year average. This storage is the foundation for this initial allocation, and with almost two months remaining in California’s rain season, we continue to hope for improved precipitation.Today's announcements reflect the low precipitation levels experienced this year in California. As we reported earlier this month, the water content of this year's snowpack is well below normal, and major reservoirs are beginning to show the effects of the lack of rainfall. In November 2011, the State Water Project's (SWP) largest reservoir, Lake Oroville, was at 80 percent of capacity with 2,825,422 acre-feet in storage, or 130 percent of normal for the date. As of midnight yesterday, storage in Lake Oroville had been reduced to 2,543,581 acre-feet, 72 percent of capacity and just about 100 percent of normal for the date. The largest reservoir for the federal Central Valley Project (CVP), Lake Shasta, has fallen to slightly below normal for this time of year and is currently at 69 percent of capacity.
