From email from Reclamation (Kara Lamb):
Earlier this afternoon [October 9], we reduced releases from Green Mountain Dam to the Lower Blue River by about 50 cfs. The reason for the change is because inflows to Green Mountain Reservoir continue to decline. We are doing our best to balance inflow and outflow at the reservoir. The change was made around 1 p.m., dropping releases from 320 to about 270 cfs.
