Update: From email from Reclamation (Kara Lamb):
Today, we adjusted releases from Green Mountain Dam to the Lower Blue River again.
The reason for the change was three-fold: increases in downstream contractor demand, increase in inflow, and increases in the amount required to compensate for the Colorado-Big Thompson Project diversions upstream on the Colorado River out of Granby Reservoir.
As a result, this afternoon we bumped releases up by 40 cfs. Flows in the Lower Blue are now around 190 cfs.
From email from Reclamation (Kara Lamb):
Just a quick message to let you know that the Shoshone Power Plant came back on-line today [December 19]. As a result, we bumped up our releases to about 150 cfs today around noon.
