1)
On June 5 we increased releases from Hetch Hetchy from 4800 to 6000 cfs. Inflows to Hetch Hetchy were higher than expected, requiring the move to increased releases today.
a.
While we do not have plans currently for additional valve moves this week, additional valve moves may be required if inflows are substantially different from forecasted.
2)
Eleanor continues to spill – inflows remain fairly high, and spill has remained steady at 200 cfs (for a total release of 950 cfs including the valves). Spill will follow inflows while the lake is full – for the next week, I expect that
inflows will maintain some spill at Eleanor.
a.
The Eleanor gauge appears to be correct.
3)
Cherry releases remain at 1000 cfs for reservoir control.
