Yellowstone National Park Fishing Report

Yellowstone National Park Fishing Report

7/3/2026


Remember that you CANNOT have felt boots, barbed hooks, or lead in the park. Keep your wits about you when fishing in the park and carry bear spray. It is common to see Bison and Bears while fishing in the park.


Firehole River: Getting a little too hot for our liking.


Gibbon River: Getting a little too hot for our liking.


Madison River: Getting a little too hot for our liking.


Gallatin River: Has been fishing absolutely stellar.  We have had one of our shop staff already run into a Grizzly Bear, so please bring you bear spray, make plenty of noise, and keep your head up!


Salmonflies, Goldenstones, Yellow Sallies, Caddis, PMD, Drakes, and the list goes on! If there's a new fly you want to try, give it a go, if it doesn't work now, it won't ever work!  They are seeing so many bugs that they seem to be getting gluttonous.   Similar to the mainstem of the Gallatin, if you want the Dry Fly fish, move your feet.



Dries:  Fluttering Bug #8, Chubby Chernobyl (Purple) #10, Henry's Fork Golden Stone #10, Elk Hair Caddis (Tan) #16, Parachute Adams (Gray) #10



Nymphs:  Pat's Rubberlegs (Black, Coffee, Brown, Olive) #8-12, Lightning Bug #14-18, Little Green Machine (Pheasant Tail, Gray) #18, Galloup's Hare's Ear (Olive) #18-20)
