Lake Granby releases increased again

Northern Water Conservancy District and the U.S. Bureau of Reclamation increased releases out of Lake Granby from 2,150 cubic feet per second to 2,400 cfs on Friday, June 12.

The increased flows are expected to fill the Colorado River below Granby Dam to bank-full capacity, according to officials with Northern Water. When the releases from the lake reached about 1,800 cfs, in conjunction with high flows in the Fraser River, the Colorado River near Hot Sulphur Springs was causing minor in the town campground.

About two weeks ago, releases from the lake were being made in coordination with releases elsewhere on the Upper Colorado River to help endangered fish near Grand Junction. Those releases were scheduled to end on June 10. The new, higher releases from Lake Granby are intended to make room to accommodate continued high inflows as area snowpack melts.

The Lake Granby pool elevation is increasing an average of 3 inches per day despite the releases, according to Northern Water.

According to Bureau of Reclamation data, Lake Granby was 96.5 percent full at an elevation of 8,277.5 feet as of Friday afternoon. The dam begins to spill on its own when the lake elevation exceeds 8,280 feet.
