From email from Reclamation (Kara Lamb):
If you’ve been out on the Lower Blue this morning [ed. October 12], you probably noticed that it’s running a little lower than yesterday. That is because this morning around 6:30, we dropped releases from Green mountain Dam by about 50 cfs. Currently, there is 850 cfs flowing below the dam. We will be making additional changes today. We will drop again at noon today, by 50 cfs, putting the Lower Blue around 800 cfs. Then around 5 p.m. today, we will drop another 50 cfs. By the end of the day, releases from Green Mountain Dam to the Lower Blue will be around 750 cfs.
The reason for the change is two fold: the 15-Mile Reach of critical habitat for endangered fish no longer needs additional water and the Shoshone Plant has some maintenance work. Reduction in flows will help both projects.
