Hetch Hetchy Water and Power reports as follows:
As the snow melts out, our release are correspondingly changing. Here are some short to medium term anticipated releases:
1)
Hetchy releases are at 2000 cfs this afternoon. We anticipate remaining at 1500-2000 cfs until the reservoir fills and spills this weekend. After fill, combined
releases (valves and spill) will follow inflows. I expect combined spill and valve releases remain less than 3000 cfs, trending down in the coming weeks.
2)
Eleanor has filled and is being managed to maintain full storage. Releases will match inflows, currently ~400 cfs. I anticipate release to decline from 400
cfs in the coming weeks.
3)
Cherry lowering continues. We are currently releasing 2000 cfs, and anticipate this to continue until the afternoon of August 6
a.
August 6 to August 30 (end date tentative) we will be closing the face valves for some preliminary valve work. During this period releases from Cherry Valley Dam < 20 cfs
b.
After August 30, releases will increase back to 2000 cfs
4)
Kirkwood Powerhouse will continues spilling 700 cfs until inflows to Hetchy drop below 1500 cfs. We anticipate 1-3 more weeks.
5)
Holm Powerhouse will continue full generation (950 cfs) through Labor Day
