YNP Report - July 3, 2025

Welcome to the first Yellowstone Park report of July—and the beginning of what many consider the best fishing of the season. Over the next few weeks, anglers will be treated to the full array of iconic hatches across all of our favorite waters in the Park.
Cicadas on the Scene
One hatch that's turning heads this season is the cicada. While not always present in strong numbers, these buzzing terrestrials are especially prolific throughout YNP this year. Roll your windows down as you drive through the Park, and you’ll hear the telltale drone of male cicadas serenading their mates. Like grasshoppers, cicadas only end up in the water by accident—but when they do, Yellowstone trout are more than willing to take advantage. You won’t find them everywhere, but it’s a smart move to carry a few cicada imitations for the coming weeks. Two of our go-to patterns are the Category 3 Churnobyl UV and the Woomfa—both high-floating, visible, and trout-approved.
Yellowstone River – Caldera Stretch
The iconic waters of the Yellowstone River in the Caldera stretch (between Chittenden Bridge and the limit below Fishing Bridge) opened for the season on July 1, and anglers were greeted with very fishable flows, prolific Salmonflies, and willing Yellowstone Cutthroat Trout. This section will likely be the crown jewel of Park fishing over the next few weeks as the parade of hatches continues with Green Drakes, Grey Drakes, PMDs, Caddis, Flavs, and Golden Stones all joining the lineup.
Northeast Corner – Slough, Soda Butte & Lamar
The Northeast Corner has officially awakened. We’re seeing varying degrees of good fishing on all three of the famed Cutthroat Triumvirate: Slough Creek, Soda Butte Creek, and the Lamar River. Green Drakes, PMDs, Caddis, and Salmonflies are all in play and driving solid dry fly opportunities.
-
Slough Creek is currently offering the best water clarity and the most consistent action.
-
Soda Butte and the Lamar are still dealing with fluctuating turbidity due to recent rains. Keep a close eye on USGS flows and don’t hesitate to call or stop by the shop before making the drive across the Park.
We expect Slough Creek to fish well through the weekend, while conditions on Soda Butte and the Lamar may deteriorate if storms continue.
Gallatin River
The Gallatin continues to show off both its abundance of wild trout and its remarkable hatch diversity. Salmonflies, Green Drakes, PMDs, Caddis, Flavs, and Golden Stones are all active, with afternoon and evening sessions offering the best dry fly windows. With a forecast calling for unsettled weather over the next few afternoons, be ready for thick emergences of PMDs, Green Drakes, and Flavs—especially in the periods right before and after thunderstorms.
Gardner River
Salmonflies are on the way out on the Gardner, but there’s still plenty of fun to be had. Prospecting the river’s pocket water stretches with a Golden Stone or Cicada pattern can produce, and morning PMDs and evening Caddis hatches offer bonus opportunities for dry fly anglers willing to put in the time.
Hoot Owl Restrictions in Effect:
Due to an overabundance of caution, the Park Service has kept in place Hoot Owl angling restrictions on the Firehole, Madison, and Gibbon Rivers. Fishing on these rivers is closed daily from 2:00 p.m. until sunrise the following morning. This unprecedented early-season move reflects how quickly water temperatures have climbed into the stress zone for trout.
We recommend giving the Madison River in YNP a complete break for now. Even early in the day, water temps are creeping beyond safe levels, and those fish deserve a rest until cooler weather returns in the fall.
For the Firehole and Gibbon, consider fishing only the furthest upstream stretches, where cooler water persists. Specifically, focus on the meadows below Biscuit Basin on the Firehole, or the upper meadow sections of the Gibbon.
Currently, these are the only waters in the park under restriction, but conditions can change quickly. Be sure to stay tuned for updates from the Park Service here.
As always, check in with the shop for the latest conditions, fly recommendations, and river updates. We’re here to help you stay dialed in for your next adventure!
