Update: From email from Reclamation (Kara Lamb):
This morning [October 2] around 9 a.m., we made an adjustment to the release from Green Mountain to the Lower Blue, dropping it back by 50 cfs from 370 to 320 cfs.
The reason for the change is to keep in balance with both declining inflows to the reservoir and the declining Colorado-Big Thompson Project diversions that occur further upstream on the Colorado River, out of Granby Reservoir.
Additional changes are possible, depending on downstream demands and weather. But, there is a slight possibility the 320 cfs could hold through the weekend.
From email from Reclamation (Kara Lamb):
This morning, Monday, Oct. 1, we saw releases from Green Mountain to the Lower Blue River bounce back up. Substitution releases from Williams Fork and Wolford Mountain reservoirs decreased today by a total of about 160 cfs. Green Mountain is now releasing that water to its downstream customers. As a result, flows in the Lower Blue increased from 210 to 370 cfs.
