From the Bureau of Reclamation:

“As of June 5, 2025, the Fontenelle Reservoir pool elevation is 6489.87 feet, which amounts to 65 percent of live storage capacity. Inflows for the month of May totaled approximately 133,000 acre-feet (af) or 76 percent of average.

Spring releases have started at Fontenelle. Releases from the dam will increase throughout spring to meet elevation targets. Per the June final forecast, maximum total release rates are forecasted to occur in mid- to late June at approximately 3,500 cfs, subject to hydrology.

The June final forecast for unregulated inflows into Fontenelle for the next three months projects much below average conditions. June, July, and August Most Probable inflow volumes amount to 240,000 af (78 percent of average), 78,000 af (46 percent of average), and 45,000 af (69 percent of average), respectively.

What this means:

Water releases from Fontenelle Reservoir are currently around 1900 CFS.

Fishing has been quite good on the Wyoming Green lately. Streamers and nymphs are currently the most productive ways of catching fish, but some summer hatches of midges, pale morning duns, and caddis are beginning to show up.
