Fishing Report - July 10, 2026
Bobby HollandUPPER HENRY’S FORK
Box Canyon is fishing really well. Large PMD hatches midday as well as some lingering golden stones on top. Big, splashy rises in the riffles are likely fish feeding on PMDs and you can get them to look up at goldens in the slacks created by larger rocks in the middle of softer runs. I like to run a double nymph rig using a rubber legs to get my flies down, followed by a smaller jig to trail. I typically use a chubby or large foam fly as an indicator but a dedicated indicator can still be effective. The Ranch is still fishing well as technical as it is. PMDs, Caddis, and Flavs are the main game right now. While the upper isn't heating up too much, the lower ranch below Osbourne can be more productive on a hot day with all its springs pumping cold water in. Pairing the right size and color with a good presentation is key to landing one of our famous ranch bows and, especially in the evening, small summer terrestrials have been very effective for beginners.
Flows: 1280 CFS
LOWER HENRY’S FORK
The warm river stretch is still fishing well. Similar to box canyon, a triple fly rig or a double nymph under an indicator is the way to go. In this section I like to shorten up my droppers a bit just to anticipate the constant changes in the river bottom. Fish are still rising to golden stones here and then starting to feed on hoppers on the sections below the Ashton Reservoir. In these waters a single nymph under a hopper (a hopper dropper rig) should allow you to cover more space in the water while still getting close to the bank. With the warm weather in the valley, water closer to St. Anthony is starting to get too hot earlier in the day so get an early start and take out before the fish get too sluggish.
Flows: 1840 CFS
SOUTH FORK SNAKE
The South Fork is a very reliable float section. The high flows have made rowing and fishing a bit of a challenge but getting the right flies deep into the soft water and hydraulics closer to the banks always makes a good day. I like a good dry drop here as well to cover the most ground and to let my flies drift over ledges and drop offs. Salmonflies are still feeding above the canyon with Goldens coming up the lower sections. PMDs will get some rises in the riffles and flats and some pocket water on the banks. Roza’s Pink Hare’s Ear Jig, Olive Mic Drops, and Duracells are the key nymphs for now, following an orange/brown rubberlegs.
Flows: 14100 CFS
MADISON
Salmonflies are making their way upstream through the wade section with Goldens following behind them. When fishing Goldens, I like to size down to entice a bite. Caddis hatches have been really consistent and the PMD hatches are huge when they’re there. Starting the day with a single small dry, then moving to a dry drop is my favorite system. We have reports that the streamer bite is inconsistent, but if you get lucky it’ll be a good time. I like a Goldie or soft two tone like a Swim Coach.
Flows: 853 CFS
PARK
The Yellowstone and the Madison are in full swing for the summer fishing season. Fish are excitedly rising for Caddis, PMDs, and Green drakes. I still like to use a royal water walker for younger, less sceptical browns. Nymphing remains highly productive during our summer thunderstorm cycles and a full day on the river should include both of the tactics in tandem for the best results.
LAKES
Callibaetis are finally going so chase the risers and lead them in the direction their head falls when they eat. Otherwise getting a Two Bit Hooker or a larger Cocktail deep is the way to go. When the water warms up, fish will find a current to cool off either in the tribs or the deeper channel so fish drop offs or major feeder creeks. Midges might still go in the early morning so fishing these as a dry or in their nymphal stage before it warms up can be effective.
TETON
The upper section is still fishing really well. I like to fish beatles and ant patterns down to a deep single nymph. Right now pheasant tails under a micro chubby or a smaller purple chubby are producing really well for me. With the hot weather, the lower is heating up earlier in the day but still fishing well. Get your nymphs deep and find the deep water to bring up colder, happier, bigger fish.
