Yellowstone River
Streamflow: 2,270 Cubic Feet per Second on August 13, 2026
As of today, Hoot Owl regulations are lifted east of Livingston. Despite warm afternoon temperatures on the upper Yellowstone, the big river continues to fish well.
Look for fish in deep, fast water or heavily aerated riffles.
Anglers have been most successful fishing nymph rigs deep early in the mornings. However, don't hesitate to work a hopper-dropper combo anytime throughout the day.
Paradise Valley Spring Creeks
The Paradise Valley spring creeks continue to be some of the most consistent fishing for trout in the area. Weed growth has been heavy this year, making fishing challenging. However, accurate casting and good drifts are producing some fine fish.
Adjustable nymph rigs are producing fish in the deeper holes. Look to sowbugs and scuds paired with a midge or small mayfly nymph as a great combination this time of year.
During the day, we have been prospecting using ants and beetles to find fish held up on the banks.
We are still seeing good numbers of western sulfur mayflies after 4 p.m. This hatch provides your best opportunity for dry fly fishing to rising fish.
Yellowstone National Park
As of August 12, Hoot Owl regulations are lifted on all YNP rivers and streams, with the exception of the Madison, Firehole and Gibbon (downstream of Norris Campground) rivers, which remain temporarily closed to fishing. With cooling temperatures, we are having great fishing in the park. The hopper season has begun in full swing on many rivers, creeks, and lakes, producing excellent fishing.
Look for strong foam lines and good current to find fish.
Get to the park early so that you can enjoy a day of fishing before water temperatures rise.
Hoppers, beetles and ants are producing great topwater action. Additionally, a beadhead nymph suspended below your terrestrial fly will put fish on the hook.
