GRAND LAKE — Pumps at the Alva B. Adams Tunnel fired up again last week, moving water from Lake Granby to East Slope reservoirs.
The Bureau of Reclamation stopped pumping in mid-September after heavy rains in Estes Park and the Front Range. Crews were working to repair damage and dredge sediment loads from reservoirs caused by the ensuing floods in the Estes Park area. As of Wednesday, Nov. 27, the Bureau began running around 60 cubic feet per second through the tunnel. Most years, it runs around 550 cfs by mid-December to refill Horsetooth and Carter reservoirs. According to public information officer Kara Lamb, the Bureau of Reclamation is still hoping to meet that schedule this season.
Currently, Lake Granby is at about 72 percent full.
“We’re probably going to see that tick down a little bit as we starting running more (water) through the tunnel,” Lamb said. “But right now, Lake Granby is staying pretty even since we’re not taking that much.”
