July brings a smorgasbord of insects to the surface of the Yellowstone River. Caddis continue to be a steady food source for opportunistic trout. Salmonflies, golden stones, and green drakes offer the chance for fishing big bugs. Pale morning duns (PMDs), and yellow sallies round out the party and become more important as the month wears on, the water warms, and flows drop.
Grasshoppers and nocturnal stoneflies begin to appear in late July and into August.

The river will be high and off-color in early July but rainbow, brown, and cutthroat trout aggressively feed on insects and other forage caught in the flow. Hungry fish will jump on flies presented tight to the banks during these conditions. The trick is maintaining a drag-free drift amidst the swirling current and avoiding the various snags hidden below the surface.
Advanced anglers can expect dry fly opportunities while fishing Paradise Valley between Carbella and Loch Leven in early July. Salmonflies and golden stone hatches can be thick at this time, but demand precision casting.
Nymphing and streamer fishing are productive throughout the river, but fish tend to congregate in the slower water next to the bank. Flies need to be presented accurately and drifts managed effectively. Accurate casts and reach mends will give the flies a few seconds to sink and settle in soft water seams. Floating the Yellowstone River in high water is a great opportunity to master this essential fly fishing technique.
Dry fly fishing is the name of the game by mid-July when the river clears. Attractor dries imitating yellow sallies or caddis can be effective all day throughout much of the river. Dry/dropper rigs using large stonefly dry imitations and weighted searching nymphs are productive as well.
Anglers fishing single, large dries through skinny riffles in late July can hook into some of the largest Yellowstone River brown trout of the season.
As flows drop in July on the Yellowstone River, many braided channels that normally don't have enough water to hold fish will be fantastic areas to explore. Some of the larger brown and rainbow trout move into these temporary areas to feed. Fish a dry-dropper through drop-offs or along foam line banks. Try a pink Chubby Chernobyl with a Kyle’s Yellow Sally or PMD nymph 4-4.5 feet off the hook bend.
