Inflows did not reach expected capacity for Flaming Gorge Reservoir during April and May, therefore the Bureau of Reclamation has decided to decrease flows to 6600 CFS for the next couple of weeks. Expect flows to increase again around the end of the month.
The Green River below Flaming Gorge Dam has higher than average flows this spring. Release flows jumped up to 8600 CFS today. There’s a nice BWO hatch on, and streamer fishing has been good. A heavy nymph rig typically does well in high water. Wading will be difficult and is not recommended; fishing from a drift should be good though! Get out there and stay safe!
Snowpack levels are above average and near 200% this year. Expect higher than average water flows through at least March 2017. See info from the Bureau of Reclamation below (to read the full article click the link here):
“(Last Updated:February 13, 2017)
Releases are currently 1,800 cfs and will be increasing within the allowable parameters of the Record of Decision, limiting increases to 50 cfs/day through the end of February. Releases will be increased to 3,000 cfs through March 2, 2017, according to the linked schedule. The February water supply forecast of the April through July unregulated inflow volume into Flaming Gorge Reservoir is 1.65 million acre-feet (169 percent of average). Additional storms throughout the basin increased the current projection to 2 maf (~200 percent of average). Current snowpack is 180 percent of median and we have received 124 percent of the seasonal peak for the Upper Green Basin with additional storm systems anticipated through February.
Flaming Gorge will be operated with the utmost caution to address the forecasted runoff. Extended bypass releases will be required to manage the runoff this year. Reclamation is advising all its stakeholders early of the extended bypass releases so that planning for the season may occur.
The Yampa River Basin has not seen commensurate snowpack accumulation to the Upper Green. The February final forecast for Yampa River flows during the April-July period is 1.4 maf (113 percent of average), with the most recent raw model guidance decreasing to 1.377 maf. Yampa River flows are largely uncontrolled, which means the current forecast provides potential relief to forecasted peak magnitude flows this spring as compared against 2011. There is always the potential of increased snow accumulation within the Yampa River Basin, so please plan accordingly.
Unregulated inflow into Flaming Gorge Reservoir during the month of January was 49,000 af, or 122 percent of average. The reservoir elevation is 6,022.9 (82 percent of live capacity) and decreasing.
The February final forecast for inflows for the next three months projects above average conditions: February, March and April forecasted inflow volumes at 50,000 af (112 percent of average), 135,000 af (132 percent of average), and 225,000 af (169 percent of average), respectively. “
Salt Lake Tribune and Channel 13 News both released stories today asking visitors on the Green River below Flaming Gorge Dam to exercise caution during spring runoff flows. Several visitors have needed rescuing during the 8600 CFS flows, and with water temps in the 40’s hypothermia is a concern. Read the tribune story here.
Once the high water flows end the dry fly fishing is expected to EXCEPTIONAL. The fish are strong from fighting the powerful currents and are putting up a good fight. We look forward to their SLAM on some dries when the CFS stabilizes to average summer flows. If you were jonesing for the (absent) Cicada hatch this year – the dry fly fishing to come could give you that top of the water eat you were looking for. Contact firstname.lastname@example.org to book ASAP- we still have some dates open!
New flow chart of Green River spring 2015 high water runoff. Watch for 8600 cfs for about 10-14 days after intial increase starting on May 11, 2015. Should be good nymphing once the run off stabilizes- around the 14th.
