The recent onslaught of El Nino storms only slightly increased the levels of California reservoirs that now stand at half of historic depths for this time of year, federal officials said Friday while releasing an initial water outlook for 2016.The U.S. Bureau of Reclamation says it is too early to determine specific water allocations in the valley.
The bureau said Lake Shasta — the state's largest reservoir, located in Northern California — is 68 percent full, while San Luis Reservoir in Central California is at 20 percent of its historical average for this time of year.....

The state Department of Water Resources, which manages part of California's vast water system, said in early December that it anticipated releasing 10 percent of supplies sought by farmers this year — half of the last year's allocation.
