Flaming Gorge Dam







Current Yampa River at Deerlodge flows are 770 cfs, Green River at Jensen, Utah average daily flow is 2,700 cfs and Flaming Gorge average daily release is approximately 1,700 cfs.  Yampa River flows are forecasted to decrease to 300-400 cfs beginning July 28, 2014.  The targeted average daily base flow on the Green River at Jensen, Utah is 2,400 cfs through September 30, 2014

Therefore, in order to maintain 2,400 cfs daily average flow on the Green River at Jensen, Utah, Flaming Gorge releases will be increased to an average daily release of 2,000 cfs.  The increase will begin on Tuesday, July 29, 2014, according to the linked schedule.  After the final change on Sunday, August 3, 2014, releases will remain at an average daily release rate of 2,000 cfs until further notice.

Below are links to the Colorado Basin River Forecast Center daily updated forecast for the Yampa River at Deerlodge Park, CO and Green River at Jensen, Utah.




Unregulated inflow into Flaming Gorge Reservoir during the month of June was 427,000 acre-feet (AF), or 121 percent of average. Observed inflows are averaging 2,000 cfs.  Flaming Gorge releases are currently 1,675 cfs average daily release with hourly fluctuations for hydropower.  The base flow target is to maintain 2,400 cfs on the Green River measured at Jensen, UT.  Releases will be increased through September 30th as the Yampa River decreases this summer to maintain flows of 2,400 cfs.

The final determination of the hydrologic classification, based on the May final forecast of the April-July unregulated inflow into Flaming Gorge Reservoir, is average (above median) for the spring flow period as outlined in the February 2006 Record of Decision - Operation of Flaming Gorge Dam Final Environmental Impact Statement

The June final forecast of the April-July unregulated inflow volume into Flaming Gorge Reservoir is 1,320,000 AF (135% of average). Inflows for the next three months are projected to be above average: with June, July and August forecasted inflow volumes at 640,000 AF (164% of average), 219,000 AF (104% of average), and 92,000 AF (104% of average), respectively.  

On May 16, 2014, the Flaming Gorge Technical Working Group (FGTWG) published the Proposed Flow and Temperature Objectives for 2014. Additional information regarding the FGTWG hydrology summaries and meeting summaries are also available online on the Technical Working Group page.

As in the last three years, Reclamation again will be involved in a cooperative experimental program (Larval Trigger Study Program or LTSP) this year where the capture of endangered larval razorback sucker is the “trigger” to increase releases from Flaming Gorge Dam this spring. Reclamation plans to coordinate with scientists involved in real-time monitoring on the river to determine the first appearance of larval razorback sucker. Biologists will begin sampling light traps in the middle Green River today, Monday, May 12, to determine the initial presence this year.  The U.S. Fish and Wildlife Service (FWS) will be regularly sampling for larval Razorback Sucker and data will be processed and shared when available.  Upon detection of larval presence, Reclamation will increase releases from Flaming Gorge in an effort to entrain larvae in backwaters where they have a better chance of survival.  Reclamation anticipates at least 3 days notification in the event larval presence is reported and Flaming Gorge Dam releases are increased.  Reclamation will determine the appropriate level of releases from Flaming Gorge Dam to achieve the goals of the experimental program, and is planning on releasing above powerplant capacity (~4,600 cfs) to full bypass (8,600 cfs) to achieve those goals.


The next Flaming Gorge Working Group meeting is scheduled for August 21, 2014, at the Utah Department of Natural Resources building in Vernal, Utah.  The Flaming Gorge Working Group is an open public forum for information exchange between Reclamation and the stake holders of Flaming Gorge Dam. The public is encouraged to attend and comment on the operations and plans presented by Reclamation at these meetings. Meeting notes from past Working Group meetings are posted on the Working Group webpage.  For more information on this group and these meetings please contact Ed Vidmar at 801-379-1182.

The April 24, 2014 Flaming Gorge Working Group has been posted online. Past working group meeting summaries and can be accessed on the Working Group pages.
