River Flow Below Holm Powerhouse

In the tables that follow, each date is color-coded according to the kind of release scheduled for that day:

Color	Meaning
	No scheduled release planned for this day.
	Scheduled release: 1100 cfs total estimated releases from the HHWP project from 7am to 11am.

Note: All information provided by Hetch Hetchy Water and Power.
Note: In the tables that follow, the release times (7am to 11am) are from Holm Powerhouse, however the projected minimum flows (1100 cfs) are at Meral's Pool.  Since the Tuolumne and sidestreams also contribute flow, the releases from Holm Powerhouse will always be somewhat less than the scheduled flow at Meral's Pool.
Note: Things can change, especially during snowmelt.  See the current Dreamflows Bulletin Board thread as well as links on the flow reports for late-breaking news.

Water Management Issues:

2.  This is a relatively low-water year, so the "other streamflows releases" referred to in the previous item aren't expected to be huge, but they may nevertheless be significant, especially during May and early June.  Before heading out, be sure to check the relevant Dreamflows flow report and Bulletin Board thread to determine current and expected release trends.

3.  Users should be aware that sudden changes in powerhouse or dam releases may occur at any time due to emergency mechanical or electrical conditions.  Scheduled or unplanned rapid changes in water levels and flow rates can create hazards, and users are urged to use caution and to wear all appropriate personal protective equipment.
