Yellowstone: Afternoon Fishing Closures on Three Rivers
On the Madison, Firehole, and Gibbon, fishing is currently closed from midday to sunrise to protect the park's trout.
Planning to fish for trout in Yellowstone? A temporary rule is about to shake up how you schedule your days, and you'll want to know about it before you rig up your rod.
Three waterways are affected: the Madison, the Firehole, and the Gibbon (for the Gibbon, only the stretch downstream of Norris Campground). On these sections, fishing is currently closed every day between 2 p.m. and sunrise. Here's what that means for your plans. You can fish early in the morning, but by mid-afternoon you'll need to pack up your gear until dawn the next day.

Why the tight window? It comes down to water temperature. When it climbs in summer, the park's wild and native trout get stressed, and a fish released after a fight recovers far less well. By shutting down the hottest hours, the park gives these populations a break. The rule stays in place until the water cools, with no end date announced, so treat it as active for any visit right now.
The good news is that this closure only applies to those three rivers during the hours listed. The rest of Yellowstone's waters are still open to anglers, as long as you follow the park's usual rules, with a valid permit, catch limits, and approved areas. Just check the conditions for the spot you're targeting before you head out, since seasonal regulations vary from place to place.
One last tip from the field. Plan your fishing on the Madison, the Firehole, or the Gibbon first thing in the morning, when the light rakes across the landscape and the water's still cool, then switch to something else in the afternoon (a hike, the geysers, an overlook). You'll find plenty of ways to round out a day like this in our Yellowstone park guide, and if you're putting together a bigger trip, take a look at our road trip itinerary that runs through the park to link up your stops stress-free.
