Heavy precipitation has filled California reservoirs that are at 118 percent of their average levels for late winter.  Shasta Lake (47 miles²in surface extent) is at 87 percent capacity and Lake Oroville (25 miles²) is at 82 percent.

In addition, storms have increased snowfall on the Sierra Nevada with the snow pack now at 86 percent of normal up from 28 percent a few weeks previously.  The Department of Water Resources has increased its allocation of supplies to 15 percent of full allotment, up from 10 percent in December.  The State Water Project will reassess allocations through March.

The extent of refilling aquifers that have been depleted is however important for long-term function of wells. Many egg complexes rely on subterranean water for their flocks, in addition to evaporative cooling and processing.
