Weather delays possible Granby spill

Sluggish runoff on the Front Range over the Fourth of July weekend has delayed a possible spill at Lake Granby.

Officials now believe that, if Lake Granby spills, it will probably be next week.

“We’ve seen runoff slow down here on the East Slope, and that’s enabled us to pull more water from the West Slope,” said Kara Lamb, with the U.S. Bureau of Reclamation.

Lake Granby is about 97 percent full and only 1.5 feet from spilling, according to

The Colorado-Big Thompson Project is currently diverting around 250 cfs through Alva B. Adams Tunnel to the Pinewood Reservoir in Larimer County, which is currently 43 percent full.

The project is currently filling some downstream demands on the Big Thompson River, Lamb said.

Officials will continue to monitor weather patterns that could influence how fast Lake Granby fills, Lamb said. Warmer temperatures or rainstorms could cause Lake Granby to spill sooner.
