| Yesterday, Hetch Hetchy Water and Power reported as follows:
"As of today, access is limited by the Forest Service due continuing effects of the Rim Fire. Public access to the Main Tuolumne/Merals Pool launch on Lumsden Road (1N10) as well as the Upper Tuolumne/Cherry Creek launch at Holm Powerhouse off of Cherry Lake Road (1N07) is limited to shuttle service only: 1-209-559-4605. A permit is required to float between Cherry Creek and Merals Pool and from Merals Pool to Ward's Ferry. Free permits can be picked up at the Groveland Ranger Station during business hours. The following link has additional details on the restrictions:

There is scheduled maintenance April 15 at Holm Powerhouse - no extra generation is scheduled for this day. Expect ~250 cfs in the Tuolumne.
Lake Eleanor is currently spilling at 220 cfs, and is expected to continue at this level tomorrow. To manage lake levels, HHWP will increase valve releases to 600 cfs on Saturday, April 12, for 6-10 hours. Ramping up and down will be between the hours of 9AM and 5PM. We expect Eleanor spill to drop after the increased release. Tuesday we will install the stop logs, which will further reduce spill.
The table below shows the days and times HHWP is scheduled to generate at Holm Powerhouse. As always, unanticipated events may reduce or eliminate generation. All generation times will be at full capacity: 950 cfs from Holm PH. An additional 35 cfs is being released from Hetch Hetchy, 12 from Eleanor, and 5 from Cherry.
| Day | Date | Release Times | Holm PH Release
| | Fri | Apr 11 | 7AM to 4PM | 950 cfs

"Rafting People!
One unit at Holm Powerhouse went down this morning at 7AM. We are sending people up to fix the problem, but do not expect a solution for at least 2 hours. Rafting flows may not occur at all today, depending on how the repairs go. We will generate full with one unit, and expect flows to stay at 550 cfs in Cherry Creek, and 625 cfs in the Tuolumne River.
We do not anticipate this problem extending to tomorrow, but will let you know as the repairs progress."
