Shasta Lake Rises 30 Feet: Winter Storms Fill California Reservoir

California's largest reservoir, Shasta Lake, experienced a dramatic rise of over 30 feet in just two weeks due to intense winter storms. This substantial inflow, with the reservoir climbing 10 feet in a mere three days around the New Year, brought its capacity to nearly 80%. This surge significantly improved the water outlook for the state.

This replenishment is welcome news for cities and farms statewide, as reservoirs are now running ahead of average. Michael Anderson, state climatologist, noted "over 100 hours of atmospheric river conditions" impacted California just before the new year, contributing to this improved situation.

Despite the recent gains, concerns remain about the snowpack in the northern Sierra and southern Cascades, which stands at only 67% of average. This snowmelt is vital for maintaining reservoir levels after the rainy season concludes, highlighting the need for continued precipitation.
