Bureau, DWR Increase 2012 Water Supply Allocations

Citing an unusually wet spring and good carryover storage, state and federal agencies increased water supply allocation estimates for 2012.

Customers of the State Water Project will receive 60% of requested supplies this year, the Department of Water Resources announced today. This is up from the 50% delivery estimate announced in February.

Most Central Valley Project contractors will also see increases in their 2012 water supply allocation, according to an April 13 announcement by the federal Bureau of Reclamation.

Agricultural contractors north of the Delta will see the biggest increase, receiving 100% of their requested supplies, up from an initial 30% allocation. Municipal and industrial users north of the Delta will also receive a full allocation, up from 75% initially projected, as will Sacramento River settlement contractors.  

South of the Delta contractors will see a more modest increase, with agricultural contractors poised to receive 40% of requested supplies, up from 30%, and municipal and industrial users’ allocation remaining unchanged at 75%. San Joaquin River exchange and settlement contractors will receive a full allocation, up from 75%.

On April 13, precipitation in the Sacramento River Basin was 81% of the seasonal average to date, precipitation in the San Joaquin River Basin was 58% of the seasonal average to date, and the snow water content ranges from 81% of the April 1 average for the Northern Sierra to 32% for the Southern Sierra.

Lake Oroville in Butte County, the SWP's principal reservoir, is at 110% of average for the date (88% of its 3.5 million acre-foot capacity). Lake Shasta north of Redding, the CVP's largest reservoir with a capacity of 4.5 million acre-feet, also is at 110% of average (93% of capacity).
