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.<br />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.
