Lake Estes and Olympus Dam
In anticipation of a jump in runoff tonight in the Big Thompson River, we will increase releases out of Olympus Dam to 175 cfs. This is a tiny increase that should not have any impact on any activities along the Big Thompson Canyon.
At 9:00 p.m. tonight, releases will increase to 225 cfs to the Big Thompson Canyon to pass inflow. At midnight, we will begin a series of increases, in 50 cfs steps, until reaching 425 cfs. The flow will be noticeable, but it does not present any ...concern.
Additionally, the Big Thompson Powerplant and the Wasteway will be returning another 550 cfs at the mouth of the Big Thompson Canyon. That water is taken away from Lake Estes through the Olympus Tunnel and the southern arm of the system to generate power, which helps to keep the canyon flows lower.
It is highly likely that the releases from Olympus Dam will go higher as the week progresses. We will do everything we can to keep those releases as low as possible.
