From the Bureau of Reclamation:

“As of November 09, 2025, the Fontenelle Reservoir pool elevation is 6488.56 feet, which amounts to 63 percent of live storage capacity. Inflows for the month of October totaled approximately 33,393 acre-feet (af) or 74 percent of average.

Current releases are 800 cfs. A winter base flow release will be set in mid-November after receiving the November forecasts. The winter base flows are set to a constant release rate from mid-November to approximately mid-March, depending on winter icing conditions. Pending hydrology, winter releases will be approximately 800 cfs.

The November final forecast for unregulated inflows into Fontenelle for the next three months projects below average conditions. November, December, and January Most Probable inflow volumes amount to 32,000 af (77 percent of average), 25,000 af (78 percent of average), and 23,000 af (77 percent of average), respectively.

Please refer to the following link for Green River flow projections, through Green River, WY, provided by the Colorado River Basin Forecast Center: CBRFC Green River, WY Projection..”

What this means:

Water releases from Fontenelle Reservoir are currently around 850 CFS.

Brown trout are currently spawning on the entire Green River system. Please be mindful of spawning fish to ensure the future of the fishery.

There are currently less weeds than normal for this time of the year on the Wyoming Green due to a spike in river flows to 5,600 CFS in early November. Fish are beginning to move into their winter holding lies. Look for trout in deeper, slower runs. The streamer fishing has been more productive than usual this Fall due to the lack of moss in the water. I have found ginger, white, gold, and black to be the best colors lately.

Current snowpack in the Upper and Lower Green River Drainage is sitting at 62 percent of normal. Current water year to date precipitation in the Upper Green River Drainage is 112 percent of normal. Current water year to date precipitation in the Lower Green River Drainage is 120 percent of normal.
