Southwest Wyoming Fishing Report

From the Bureau of Reclamation:

“As of May 7, 2026, the Fontenelle Reservoir pool elevation is 6478.92 feet, which amounts to 46 percent of live storage capacity. Inflows for the month of April totaled approximately 45,915 acre-feet (af) or 54 percent of average.

Current releases are 800 cfs. This release is expected to remain constant through May.

The May final forecast for unregulated inflows into Fontenelle for the next three months projects much below average conditions. May, June, and July Most Probable inflow volumes amount to 65,000 af (37 percent of average), 165,000 af (54 percent of average), and 79,000 af (47 percent of average), respectively.

What this means:

Water releases from Fontenelle Reservoir are currently around 633 CFS.

The flows are low, but consistent. Sow bugs, baetis, worms, and midges have been working best. On some days there have been windows of dry fly activity with terrestrials. The streamer fishing continues to produce with sculpin, baitfish, and crayfish patterns.

Current water year to date precipitation in the Upper Green River Drainage is 98 percent of normal. Current water year to date precipitation in the Lower Green River Drainage is 92 percent of normal.

Weber River Fishing Report

Releases out of Rockport Reservoir are currently at 196 CFS.

The river near Coalville is currently flowing at 258 CFS.

Releases out of Echo Reservoir are currently at 304 CFS.

River flows by Mountain Green are at approximately 314 CFS.

Summer hatches have not yet started on the Weber River, but I would be on the lookout for a few remaining Mother’s Day Caddis. If you are nymphing, try caddis, worms, sow bugs, and scuds. Now that we are seeing more water in the Weber, fishing streamers tight to the bank might be effective as well.

The current water year to date precipitation is the Weber River Drainage is at 87 percent of normal.

Small Stream Fishing Report

Now is a great time to target many of Utah’s small streams. Most high mountain access roads are open for the season and the fishing is heating up. Depending on where you are at in the state, you can run into salmon flies, cicadas, green drakes, caddis, midges, pale morning duns, and some early season terrestrials. Get it while the getting is good.

Southwest Wyoming Fishing Report

From the Bureau of Reclamation:

“As of February 09, 2026, the Fontenelle Reservoir pool elevation is 6480.97 feet, which amounts to 49 percent of live storage capacity. Inflows for the month of January totaled approximately 32,146 acre-feet (af) or 106 percent of average.

Current releases are 800 cfs. This release is expected to remain constant throughout the winter base flow period, pending significant hydrologic changes or emergencies. The winter base flow is typically from mid-November to mid-March, pending icing conditions on the Green River downstream of the dam this coming spring.

The February final forecast for unregulated inflows into Fontenelle for the next three months projects below average conditions. February, March, and April Most Probable inflow volumes amount to 25,000 af (88 percent of average), 50,000 af (88 percent of average), and 75,000 af (89 percent of average) respectively.

What this means:

Water releases from Fontenelle Reservoir are currently around 850 CFS.

Fish have moved into their winter holding lies. Look for trout in deeper, slower runs. Even with the warmer temperatures, there has been minimal midge activity. As with most winters on the Wyoming Green, the fishing is better the closer you are to the dam. The streamer fishing has been consistently decent as of late. I have found silver, ginger, pearl, white, gold, and black to be the best colors, with olive occasionally making an appearance.

Current snowpack in the Upper Green River Drainage is sitting at 71 percent of average. Snowpack in the Lower Green River Drainage is sitting at 41 percent of normal. Current water year to date precipitation in the Upper Green River Drainage is 106 percent of normal. Current water year to date precipitation in the Lower Green River Drainage is 96 percent of normal.
