Colorado-Big Thompson Project update: 124 CFS in the river below Olympus dam


From email from Reclamation (Kara Lamb):

The continuing heat is generating some early season run-off. With highs in the low 80s, we are anticipating some run-off tonight down the Big Thompson River and into Lake Estes. We will bypass that increase through the dam, on down the Big Thompson Canyon. Around midnight tonight, April 23, we anticipate bumping releases up to about 150 cfs.

Earlier this month, I e-mailed that we were increasing releases from Olympus Dam to the lower Big Thompson River for similar reasons. Since that time, releases from Olympus Dam have averaged about 127 cfs. They’ve gotten as high as 159 cfs and dropped down to about 112 cfs. Currently, we are releasing about 124 cfs.

It is likely these types of fluctuations will carry on into May.

Please keep in mind that we typically make our adjustments late at night; so, the river might look different in the morning than it did the night before.
