The heavy snow melt has triggered more water releases from Lake Oroville this week. The first release through the Spillway in four years happened in March with 15,000 cubic feet per second (cfs) were released. The California Department of Water Resources upped this amount this week. On Wednesday, 18,000 cfs were released — and 20,000 cfs on Thursday…. As of Thursday, Lake Oroville was at 91% capacity….The DWR said despite the increase, the Sacramento River will remain at its normal conditions, so there is no concern for flooding.
