From email from Reclamation (Kara Lamb):
[September 13] Late tonight/early tomorrow morning, we will be cutting back releases from Olympus Dam to the Big Thompson River. Currently, flows are around 215 cfs. By early tomorrow morning, September 14, they should be under 100 cfs.
Starting last weekend, we began bumping up releases from the dam to the river in order to deliver Colorado-Big Thompson Project water to water users while a section of the Charles Hansen Feeder Canal was down for inspections. Now that the work is wrapping up, we can begin moving C-BT water back through its system again, reducing the amount of water down through the canyon.
This time of year, releases from Olympus Dam typically reflect inflows to Lake Estes. Whatever the Big T brings into Lake Estes, we pass through Olympus Dam down the canyon. Inflows to Lake Estes are currently about 61 cfs.Unless we have a significant rain event, it is likely releases from Olympus Dam will be around 61 cfs by tomorrow.
