From email from Reclamation (Kara Lamb):
As inflows to Lake Estes continue to decline and the reservoir elevation behind Olympus Dam drops slightly, we will curtail releases from Olympus Dam to the lower Big Thompson River. Earlier this morning, we closed four of the five gates at the dam. Our releases to the lower Big Thompson are now about 580 cfs and could drop further.
