Madison River Fishing Report: June 13, 2026
Summary
Fishing on the Upper Madison has been pretty decent over the last several weeks, with wind the main complaint rather than the water. The bigger story is rising flows: Hebgen is essentially full, so the dam is finally sending water downstream. That nudges the salmonfly hatch back a touch but should turn on the streamer bite over the next week.
At a glance: Flows (Slide Inn, 6/10) Hebgen Dam 699 cfs, Kirby 842 cfs, Varney 1100 cfs (rising) | Water low but climbing fast as Hebgen spills; Upper river clearing on the margins, salmonfly window opening | Hebgen Reservoir 99.6% full and rising
Fishing on the Upper Madison has been pretty decent over the last several weeks, with wind the main complaint rather than the water. The bigger story is rising flows: Hebgen is essentially full, so the dam is finally sending water downstream. That nudges the salmonfly hatch back a touch but should turn on the streamer bite over the next week.
Flows note: Flows are rising all week. Northwestern Energy began stepping releases up roughly 5% per hour (noon to 5 pm) and will keep climbing through Friday until outflow matches inflow. Expect changing levels, moving color lines, and shifting wade access day to day. Wind is the other hazard: the open middle river below Varney has been blowing 30 to 40 mph at low flows, dangerous and miserable in a boat. Stay up high or find shelter in the trees when the wind shows up.
Best techniques
- Nymphing is the workhorse by a long shot. Up top, small Pat's Rubber Legs and TJ Hookers in #10-12, plus Olive Caddis Larva, Zebra Midges, Dips, and smaller perdigons in the #16-18 range. BWO nymphs still earn their keep on the colder, cloudier days.
- Dry-dropper on the float: dropping tungsten off a Royal Micro Chubby has produced some really fun days through the float section.
- Dries are improving with small attractors and adult caddis, though they remain a distant second to the nymph rig for now.
- Streamers still are not great, but expect that to flip quickly as flows tick up. Work Mini Envys, Mini Whiteys, Double Screamers, Mini Loop Sculpin, Bangtails, and micro envys in Black, Olive, Yellow, Olive/Black, and Natural. Retrieve matters as much as pattern: some days a slow twitch or jig, other days a hard strip back to the boat, so keep experimenting until you crack the code.
Hatches and flies.
- Salmonflies: a few have been spotted down low, but a full-blown emergence is still a little ways off. Slide Inn's best guess is around June 16, roughly a week ahead of normal, though rising flows may push it back. Call the North Slide in Ennis for big-bug intel next week.
- Caddis: adults on the water; olive caddis larva working subsurface.
- BWOs: still in play as nymphs on the colder days.
- Midges: small dips and zebra midges remain steady producers in the nymph rig.
Outlook. The week is all about water coming up. Flows rising daily out of Hebgen should color things slightly, improve the streamer fishing, and set the stage for the salmonfly emergence shortly after. Keep nymphing as the bread-and-butter approach, watch the lower river for the first big bugs around the 16th, and be ready to fish streamers harder as the river fills in.
