The onslaught of rain across California this week has pushed up
the state’s reservoir water storage levels
even more since the weekend, according to state data, though levels for most reservoirs are still below the historical average for this time of year.

Statewide reservoir storage, which has declined significantly over the past three years thanks to drought and diminished snowpack, is now up to
84% of average
as of midnight on Jan. 10, according to the state department of water resources. Just five days ago, average storage levels were at only 78%, and
one month ago, at 68%.

While nearly all of the state’s largest reservoirs remain below their historical average for this time of year, the series of storms continue to push water levels up, even compared with just last week. Lake Shasta, which is the state’s largest reservoir by volume, rose from 35% to 42% of its total 4.5 million acre-foot capacity over the last five days — both up from 31% a month ago. The additions bring the reservoir to 70% of its historic average for this time of year.

Lake Oroville similarly jumped up from 41% five days ago to 47% as of Jan. 10, bringing it to 88% of its historic average.
