From email from Reclamation (Kara Lamb):
There will be some slight changes across the C-BT this weekend, but most will not notice. We are testing some of our equipment in the power plants and temporarily slowing down the flow through the project.
April 24, we will slow the rate of flow from the Estes Plant into Lake Estes. Lake Estes is currently at an elevation of 7472–only 3 feet below full. It will not be affected and should see its water elevation remain close to 7472 through the weekend.
Our releases from Olympus Dam to the Big Thompson River are not changing and will remain about 50 cfs.
Pinewood is currently rising–it is at 6575 today. Tomorrow (Saturday), it will drop again, stabalizing Sunday around a water level elevation of 6572–about 8 feet down from completely full.
Carter Lake is completely full and will remain that way for some time.
Horsetooth will continue to rise, but beginning Saturday, the inflow to Horsetooth will slow down, slightly. It is currently filling at a rate of about half a foot a day. By Monday, it will be rising a quarter of a foot a day. Currently, Horsetooth is at an elevation of 5415.75.
