Hetch Hetchy Water and Power reported May 12, 2016 as follows:
The peak release from Hetch Hetchy has now passed and flows began to ramp down this afternoon. The warm clear weather has triggered an onset of flows in the high country. We have a slight cooling pattern ahead of us for the weekend, but
warmer weather looks like it may try to return the middle of next week. We still have not seen the first “hot spell” of the spring. Below is a table of estimated releases from HHWP facilities. There are of course other accretions to add to these flows to estimate
the flow at Lumsden. Be aware that Lake Eleanor is now spilling, so the weather will affect flows from Eleanor.
Also, please be aware that on 5/17, 5/18 and 5/19 we are performing valve maintenance at Hetch Hetchy. This will cause a variation flow throughout the day, however it is captured by the range listed below.
Enjoy the higher flows this weekend and be safe.
