February 24, 2023 - Increases in Release

Increase in Release (#4)

11:45 pm USBR INCREASED Release of Water to 25,000 cfs

United States Bureau of Reclamation (Reclamation) advised SYRWCD that due to continued aggressive storm runoff and the forecast of additional of storm cells over the watershed at Lake Cachuma, they adjusted spillway releases to 25,000 cfs at 11:45 pm. They will continue to monitor reservoir elevation and runoff as the storm develops.

Reclamation also answered questions that had been raised regarding the transit time of increased water to The Narrows and Lompoc.  They advised that as their experience with "89-18" water rights releases shows, it is not easy to predict the exact transit time from Bradbury Dam to The Narrows, but the gate testing on 2/8/2023 had a transit time of 23 hours. Since the transit time tends to shorten with higher flows,  the current transit time is anticipated to be between 4 and 23 hours.
