Oroville reservoir is 65% full. Since its lowest point on Sept. 30, 2021, the massive lake’s level has risen 182 feet, boosted by nine atmospheric river storms in January.
To fill completely to the top, Oroville’s water level would have to rise another 90 feet. When the massive Sierra snowpack, which Thursday was 206% of its historical average, begins to melt in the months to come, it is sure to increase storage levels at Oroville and other major reservoirs, experts say.
