LOVELAND, Colorado – The Bureau of Reclamation expects to fill Green Mountain Reservoir in late June, leading to increased flows on the Blue River below Green Mountain Dam and in the Colorado River below the Blue River confluence near Kremmling. 

Reclamation will increase Blue River flow below Green Mountain Dam by mid-June. Green Mountain Dam release will increase to approximately 750 cubic feet per second. In addition, Reclamation will discontinue Elliot Creek diversion to reduce spillway releases. Overall, Reclamation anticipates flows in the Blue River below Green Mountain Dam could range from 500 to 1,500 cubic feet per second from mid-June through mid-July.  

“Thanks to an abundance of precipitation on the Front Range this spring, cities and irrigators are using less water from transbasin diversions and water managers have prioritized filling east slope reservoirs with water available from rivers on the Front Range,” said Reclamation’s Eastern Colorado Area Manager, Jeffery Rieker. “As a result, many east slope reservoirs have filled, and additional water will remain in the Colorado River.” 

Green Mountain Reservoir, a feature of the Colorado-Big Thompson Project, provides stored water for beneficial use within the Colorado River basin upstream of the Gunnison River confluence in Grand Junction, Colorado. Green Mountain Reservoir stores more than 100,000 acre-feet for use by West Slope project beneficiaries. This allocation is commonly referred to as the “Power Pool” and includes the 66,000 acre-foot Historic Users Pool.
