CURRENT CONDITIONS

River Flows: 3,500 CFS
Water Temperature: Mid 60’s°F
Overall Conditions: Good/Fair

The Missouri is fishing exceptionally well right now with stable flows and comfortable water temps. Things are warming up after lunch and the bite slows. Dry fly fishing has been excellent during morning and evening hours. The river’s in good shape, crowds are thinning a bit, and there are still plenty of opportunities to find good fish.

WHAT’S WORKING

Techniques:
DRY FLY – Fish the Trico Spinner fall. Tie on an Ant, or a hopper and roll. Great options on the center river flats and shorelines.

NYMPHING – Nymphing continues to produce, particularly in the early hours. The upper rig (Zirdle Bug, Thin Mint Bugger, or crayfish pattern) paired with a smaller dropper — think Tailwater Tiny, Frenchie, Perdigon, or a classic Pheasant tails variations — has been a consistent setup.

Top Producing Flies:

DRY FLIES

• Corn-Fed Caddis
• Royal Chubby
• Adams
• Morrish Hopper

NYMPHS

• Warrior Perdigon
• Frenchie
• Hairs Ear

STREAMERS

FORECAST – LOOKING AHEAD

August is what it is — hot, dry, and a little slower in the afternoons. But that doesn’t mean the fishing shuts down. You just have to think like a trout: feed in the morning, chill in the heat. Early starts, stealthy approaches, and a willingness to adjust tactics throughout the day will keep you in the game.
