Colorado-Big Thompson Project update: 340 cfs in the Big Thompson below Olympus dam


From email from Reclamation (Kara Lamb):

As our maintenance work continues into November, folks along the river and Horsetooth Reservoir have likely noticed a few more changes.

After releases from Olympus Dam to the Big Thompson River went up Thursday and Friday last week, they briefly cut back again for some maintenance work at the Dille Diversion Dam in the lower part of the canyon. That work was completed yesterday. As a result, releases from Oly Dam went back up and we are now sending about 340 cfs down the Big T from the dam. We anticipate this release to continue for about two weeks.

With maintenance complete at the Dille Diversion, we are now using it to capture about 300 cfs from the river to send north to Horsetooth Reservoir. With about 300 cfs coming in, Horsetooth’s water level elevation has started to rise again. It’s gone up about six inches since yesterday and is at an elevation of 5400.40 feet.

From email from Reclamation (Kara Lamb):

The ramping down of releases from Green Mountain Reservoir that started last week continued through the weekend and into today

By yesterday, releases had been cut back in 50 cfs intervals to 400 cfs. Today, we followed the same pattern the past few days have seen and cut releases by 50 cfs at 8 a.m. and again at 5 p.m. resulting in a flow of about 300 cfs in the Lower Blue.
