Warm Weather Brings Early Hoot Owl Restrictions in the Park
Well folks, we saw this one coming. Unseasonably warm and dry conditions have prompted the National Park Service to implement hoot owl restrictions on the Firehole, Gibbon, and Madison Rivers inside Yellowstone—just a few short weeks into the season.
Effective immediately, fishing on these rivers is closed daily from 2:00 PM until sunrise the following morning. This is an unprecedented early-season move, and it reflects just how quickly water temperatures have climbed into the stress zone for trout.
We recommend giving the Madison River in YNP a full break for now. Even early in the day, water temps are creeping up beyond safe levels, and those fish deserve a rest until things cool back down in the fall.
On the Firehole and Gibbon, consider fishing only the furthest upstream stretches where cooler water persists. Think the meadows below Biscuit Basin on the Firehole, or the upper meadow sections of the Gibbon.
At the moment, these are the only waters in the Park under restriction, but that could change quickly. Stay tuned for updates from the Park Service HERE.
What’s Next in the Park?
Outside of those closures, options in the Park remain a bit limited this week as we’re still just a bit early for many of our favorite Cutthroat fisheries. The Yellowstone River inside the Caldera doesn’t open until July 1, and up in the Northeast Corner, Slough Creek, Lamar River, and Soda Butte Creek are still running high and a little off-color. But they are close, and things could come into shape fast.
In the meantime, the Gardner, Gallatin, and Snake Rivers are your best bets for the coming week. These fun and productive fisheries are rounding into form, and we expect to see the first good hatches of PMDs, caddis, Green Drakes, Golden Stones, and Salmonflies showing up any day now. This weekend’s cooler weather may hit the brakes briefly, but the hatch train is still very much on schedule.
As always, check in with the shop for the latest conditions, fly recs, and river updates—we’re happy to help you stay dialed in.
