Hetch Hetchy Water and Power reports as follows:
A couple of changes to flows this week:
1)
Eleanor continues to spill – inflows remain fairly high, and spill has remained steady at 300 cfs (for a total release of 1000 cfs including the valves). Spill will follow inflows while the lake is full – for the next week, I expect
that inflows will maintain at this high level.
a.
Note that the Eleanor stream gauge is back up and running. However, it is currently over reporting by 300 cfs (we are working on it).

2)
High inflows to Hetch Hetchy have necessitated a valve move to
1500 cfs today. We expect to remain at 1500 cfs through May 1
3)
May 1, we are planning a valve move to 3000 cfs at Hetch Hetchy.
