Colorado-Big Thompson Project update: 200 cfs in the river below Olympus dam


From email from Reclamation (Kara Lamb):

As we move into fall, we’re seeing some of our late season demands come on downstream of the Big Thompson River. As a result, we’ve been moving some water down from Pinewood, Flatiron and Lake Estes. Each reservoir has seen a slight drop in water elevation.

We have also increased releases from Lake Estes through Oly Dam. Monday night, we bumped releases up 75 cfs. Last night, we bumped up another 50 cfs. Consequently, this morning the Big Thompson through the canyon is flowing at about 200 cfs.

It is possible we could go up another 25 cfs late tonight. But, it is also likely flows will drop back down to below 100 cfs by Saturday morning when it is anticipated delivery of water down the Big T will drop off.

Also from Reclamation (Kara Lamb):

Flows on the Colorado River continue to drop. That means, calls for water along the 15 Mile Reach of critical habitat for the endangered fish are up slightly. As a result we have increased our release from Green Mountain to the Lower Blue. Yesterday around 5 p.m. we released another 50 cfs. That means the Lower Blue is currently around 650 cfs.
