Colorado-Big Thompson update: Reclamation is moving water through the Adams Tunnel

From email from Reclamation (Kara Lamb):

Just a quick note to let you know that we are finishing up our annual maintenance on the east slope of the Colorado-Big Thompson Project. That means, we have begun to once again divert water through the Adams Tunnel from Granby and Shadow Mountain reservoirs on the West Slope.

We began the trans-basin diversions last week. With water starting to come back through the tunnel, the water level at Lake Estes began to rise. Tonight, the reservoir is at an elevation of about 7470 feet. That’s roughly five feet down; pretty average for this time of year.

Yesterday, 12-12-12, we began sending water through Olympus Tunnel to Pinewood Reservoir. Today, the reservoir started at an elevation of about 6563 feet and is on the rise.

This morning, we turned the pump on to Carter Lake. With the hot and dry summer and fall, the water level elevation at Carter dropped to 36% of its full content; an elevation of 5686 feet, or about 73 feet down from full. With the pump back on, water levels should start slowly ticking up again.

Likewise, we are once again sending water to Horsetooth; although with the pump on to Carter, inflows to the reservoir will likely fluctuate between 100-200 cfs. Horsetooth got down to a water level elevation of roughly 5377 feet, or 44% full. It’s water level will now slowly start rising, too.
