Yellowstone's Warm Weather Fishing Restrictions

As of Saturday, July 12, Yellowstone National Park has instated fishing restricitons. Because of high water temperatures and low water flows, the park has closed several popular fisheries across the national park. Here's everything you need to know about summer fishing in Yellowstone National Park.

We know that fly-fishing is a highlight for many locals and visitors alike. So don't worry — even though there are closures in Yellowstone, there's still plenty of great fishing to be had in and around Jackson Hole!

Fishing Closures in Yellowstone

These fisheries are closed to all fishing:

• The Madison River and all associated tributaries.
• The Firehole River and all associated tributaries.
• The Gibbon River and all associated tributaries downstream of Norris Campground.

Officials said that "the closure will be reassessed when water temperatures cool and flows return to more typical summer conditions," meaning that these restrictions may not be in place for the remainder of the summer season. "Water temperatures have exceeded 68 degrees Fahrenheit (20 degrees Celsius) in recent days and flows on many rivers, streams and creeks are low. These conditions are extremely stressful to fish and can be fatal."

"Staff will continue to monitor park rivers and streams for warm temperatures and low flows, and watch weather forecasts. The extended forecast calls for continued hot and dry conditions with a slight chance of isolated afternoon thunderstorms, which contribute to continued low stream flows and warm-water temperatures," they added. Additional closures may be implemented if conditions require.

Where is fishing open?

Fishing is open on the park's lakes — including Yellowstone and Lewis Lakes — as well as rivers and streams that aren't listed above. Not sure about a certain spot? Just check in with the rangers at an entry gate or visitor center. 

"On rivers, streams and creeks that remain open or unrestricted, please fish during the coolest times of day and land fish quickly. Do not play hooked trout to exhaustion. Gently handle fish in the water as much as possible and let them recover before release. Your cooperation will protect the park’s fisheries," stated officials. 

There are not currently any closures in place in Grand Teton National Park or around Jackson Hole, but the advice for handling fish gently and aiming for the cooler parts of the day still applies. 

One of the best ways to make sure that you're fishing in a thriving spot and handling fish well? Reserve a day with a guide! It's a sure-fire way to have a great day on the water and find elusive trout even if conditions are a bit warm.
