Yellowstone National Park Fishing Report

Update: Yellowstone lifts remaining fishing restrictions for Firehole, Madison and Gibbon rivers

MAMMOTH HOT SPRINGS, Wyo. – Effective Friday, Sept. 4, 2026, the remaining fishing restrictions on the Firehole, Madison and Gibbon (downstream of Norris Campground) rivers and all associated tributaries will be lifted due to cooling weather and water temperatures. Anglers will be able to fish these rivers, in addition to most other park rivers, streams and lakes, daily from sunrise to sunset as specified in the 2026 Fishing Regulations booklet.

Full fishing closures on these rivers were initially implemented July 15, then scaled back to partial restrictions Aug. 28 as conditions improved. The restrictions and closures were necessary during a period of low water flows and high water temperatures exceeding 68 degrees Fahrenheit (20 degrees Celsius) that can be lethal to fish.

Staff will continue to monitor the water temperatures. Temporary restrictions or closures may be implemented depending on condition assessments.

The Fall fishing season is starting up in Yellowstone National Park. There is a multitude of different options for anglers in Yellowstone National Park as summer ends and fall begins.

The northeast side of the Park – Lamar, Soda Butte and Slough Creek is still in good fishing shape but watch these rivers flows due to recent rain storms. Dry dropper set ups will be effective in covering water. Standard foam hoopers/attractors paired with pheasant tail, hare’s ears and other patterns like Duracells and perdigons will be effective. Anglers will most likely see BWOs as well as Terrestrials be the main focus for bugs.

The Madison, Firehole and Gibbon rivers should be back in good shape after many weeks of being closed due to high water tempatures. Look for the shorter days and nights to bring water tempatures back down for the fall fishing season. Look to swing soft hackles and small streamers on intermediate or slow sinking poly leaders to be productive. Hatches are going to be limited to mostly BWOs and some leftover Caddis. Warm days and nights should keep Terrestrials active as well. Look for the Madison Brown trout to start getting aggressive.
