Fly Fishing Report – Mid-Summer

What are the fish biting on today? Check back often for our latest Jackson Hole Fly Fishing Report update!

July 31, 2025

Snake River

The Upper Snake River here in Jackson Hole has been fishing well with smaller attractors, parachutes and dropper flies. Its the time of the year to go early and end around lunch so watch water temps, if it gets above 67-68 probably best to have a cold beer and relax in the shade.

PLEASE, FISH BARBLESS HOOKS AND TAKE CARE OF OUR PRIZED NATIVE CUTTHROATS!

Snake River Tributaries

Our Snake River tributaries are very low and many fish have settled back into the main river. Mornings are good with small attractors or mayfly parachutes. The Buffalo Fork is a bit better mid day so plan and go have an adventure!

Lava Creek Ranch

Fly Fishing for Trophy Rainbows and Tiger Trout with Grand Teton Fly Fishing!

Reports are mixed but getting some big trout on dry attractors and dropper combinations.

Small leech streamers also producing.

Give us a call if you want to reserve a day on this private trophy trout lake!

Salt River

Flows are low but the fishing is holding up and the big fish are held up in deep runs. Terrestrials are the way to go, ants and hoppers from 11am-5pm on the windy days.

Teton Park Lakes

JACKSON LAKE: Weekdays are best and try wind blown shorelines with large ants. Lake trout are more in the 40-80′ level and spread out in the full lake.

JENNY LAKE: No recent fishing report, update is there will be no boat access in 2025 due to construction. Flying Ants!

Green River

Flows are quite low and getting warm in the lower reaches by noon so plan accordingly. Overall the bite is technical with spooky trout on grassy flats and riffle runs or banks. Rusty spinners and beetles are a good option or try a dropper below a small (#16) black water walker, 10-11′ leader helps!

Yellowstone National Park

Lakes are slowing down for the dog days. Most hatches are now ending and the fish will spread out and drop a bit deeper to avoid the warm surface temps There is however a terrestrial bite that can happen in some areas where grass and wind place ants or hoppers on the lake regularly, still super fun and productive!

Many small streams on the west side are closed, the Yellowstone and Lamar Rivers are best wading options. Hoppers!
