From email from Reclamation (Kara Lamb):
Northern Water is ending the non-charge program on Wednesday, May 11–tomorrow morning. As a result, the pump up to Carter Lake will go back on and inflows to Horsetooth Reservoir will pick up. The delivery of water through the concrete chute at the mouth of the Big Thompson Canyon will also end.
By tomorrow afternoon, upwards of 220 cfs will be flowing into Horsetooth Reservoir. Both it and Carter Lake are expected to begin rising again.
Meanwhile, the warm days over the weekend have generated a little melting snow coming into Lake Estes up in Estes Park. As a result, we have been bumping up releases from Olympus Dam to the Big Thompson River. Tonight, May 10, at midnight, releases will bump up again to about 200 cfs.
We are also updating our webpages as we move into the spring run-off season. When you visit us on-line, be sure to check the menu on the left side of the page for updates on other features around Reclamation’s Eastern Colorado Area Office. We are also tracking snow pack and reservoir levels.
