United States Bureau of Reclamation (Reclamation) advised SYRWCD that the Cachuma Reservoir was past the peak inflow of 31,000 cfs and maximum discharge of 25,000 cfs generated by the unexpectedly severe February storm event. As of February 25, at 4:30 pm, releases at the dam were 14,500 cfs and expect to be reduced each hour in compliance with National Marine Fisheries Service reviewed ramp down tables.
Reclamation anticipates reaching a controlled discharge of 2,000 cfs no earlier than 9:00 am on Sunday 2/26, but may pause the ramp down for an hour at a time if reservoir inflow is higher than the planned reduction. Once reservoir discharge reaches 2,000 cfs, they plan to hold releases steady, as needed, to establish sufficient storage volume to drink in the persistent runoff from the past storm as well as the rainfall anticipated in the next few days. Current estimates have the approximate reservoir elevation of 751 ft.
