Update on flows for May 31 to June 6:
1) On May 30 we reduced releases from Hetch Hetchy to 4800 cfs. We plan on keeping releases at 4800 cfs until June 12, at which point we will reevaluate inflows and storage conditions.
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.
4) Maintenance at Kirkwood Powerhouse will require reducing spill at Early Intake from 700 cfs to 0 cfs from 8PM tonight, May 31st through 5AM on June 2nd.
