Upper Madison River Fishing Report

Hebgen Dam to Ennis Lake

Below Hebgen Dam the river drops into Quake Lake, and from there down to Ennis Lake it runs roughly fifty miles of almost continuous riffle, the stretch anglers call the fifty-mile riffle. It is the reach most people mean when they say they are fishing the Madison, and it holds good numbers of rainbows and browns from top to bottom.

Upper Madison Fishing Report

Hebgen Dam to Ennis Lake
Water Temp (Kirby) 42.4°F
Flow Rate (Kirby) 727 CFS
Water Clarity Excellent

Kirby read 736 cfs this morning at 42.6 degrees, and that's a comfortable late-fall number for the fifty-mile riffle. We got a bump in flows a while back and the river has settled in nicely since. Clarity is excellent top to bottom, which is what you'd expect with the dam filtering everything and no tributary mud this time of year. The weather has been unusually mild for November, and that's kept the fishing better than it has any right to be this late. Shop reports and my own days out this week line up: nymphing is the bread and butter, and it's been genuinely good, with the cloudy days clearly outfishing the bluebird ones. At 42.6 degrees the fish have slid out of the fast riffle water and into the slower, deeper stuff. Inside seams, tailouts, the soft water behind the big boulders, the deep slots along the banks. They're not chasing much, but they're eating, and they're podded up, so when you find one fish you've usually found ten. The midges have been hatching in solid numbers through the middle of the day, and on the gray afternoons we're still seeing a few BWOs, enough to get pods of rainbows working the flat tailouts between Lyons and Ruby Creek. It's not a blanket hatch. It's a hunt-for-risers situation, and when you find them it's rewarding, technical fishing with long leaders and small flies. The brown trout spawn is in full swing, same note as up in the park: you'll see redds on the shallow gravel bars, especially in the side channels. Stay off them. There are plenty of rainbows and whitefish sitting downstream of that gravel eating eggs, and that's fair game. Streamer fishing has been a slower grind than October but the fish that eat have been good ones. Slow presentations, smaller bugs than you threw a month ago. Remember the wade-only water, Quake outlet down to Lyons Bridge and Ennis Bridge down to the lake, no fishing from boats on either stretch, so floats start at Lyons. Honestly, this time of year I'd rather wade anyway, the fish are concentrated and you want to pick water apart slowly rather than cover miles. Between the lakes is worth a mention too, there are still run-up fish from Quake in that short stretch and it fishes well on overcast days. The Madison on the Montana side is open year-round, so there's no clock running on this water, but the pleasant weather won't hold forever and the fishing window each day is already shrinking. Ten to four is the game now. There's no reason to be on the water at first light in November, let the sun get on it and let the bugs get going. Crowds are gone. You can have Three Dollar Bridge nearly to yourself on a Thursday, which after the circus of July feels like a different river. Check the access points page if you haven't fished the wade water much, there's a lot of it and most of it gets ignored this time of year.

Tactics for today

Fish a two-fly rig under an indicator, Rubber Legs on point with the Zebra Midge or $3 Dip trailing 16 inches behind, and set your depth so you're ticking bottom in the slow deep runs. Dead drift it through the gut, then let it swing out at the tailout before you recast, the swing picks up fish that refused the drift. If you see noses in a flat tailout after lunch, clip the bobber off and go to the Sparkle Dun on a 12-foot leader with 5x, downstream presentation so the fly shows first. For the streamer, slow everything down. Quartering downstream, slow strips with long pauses, let it sink into the buckets. The grabs come on the pause right now, not the strip.

The water

Below Hebgen Dam the river drops into Quake Lake, formed by the 1959 earthquake, then exits into the slide area: steep, boulder-strewn, the most technical wading on the river.

From Lyons Bridge down to Ennis the gradient eases into the classic broken riffle: pocket water, seams behind boulders, and few obvious pools. Fish hold everywhere, which is why covering water beats working one spot.

This is the reach that made the salmonfly hatch famous. In late June and early July the hatch works upstream and the whole valley fills up.

Access

  • Quake Lake outlet: Top of the reach. Steep, rough wading through the slide area.
  • Raynolds Bridge: First bridge access below the slide.
  • Three Dollar Bridge: Public fishing access (conserved and opened to the public in 2002) with a long stretch of wade water.
  • Lyons Bridge: The most-used put-in on the upper river, and the start of the float water.
  • Palisades: Between Lyons and Ruby Creek; short float or wade access.
  • Ruby Creek: Common take-out for the Lyons float.
  • McAtee Bridge: Mid-valley access with parking and a ramp.
  • Varney Bridge: Popular put-in for the run down to Ennis.
  • Ennis: Town ramp at the bottom of the float water, above Ennis Lake.

See the access points guide for GPS coordinates, parking notes and float distances.

When it fishes

  • Winter (December–March): Midges and small nymphs in the slower water. Fish the middle of the day. Midge patterns and sizes: the hatch chart.
  • Spring (April–May): Skwalas and Mother's Day caddis, with runoff usually arriving by late May. Hatch timing for both: the hatch chart.
  • Salmonflies (late June–early July): The hatch moves upstream. Crowded, and worth it. Every stonefly pattern that works: the hatch chart.
  • Summer terrestrials (July–September): Hoppers, ants and beetles along the banks, with caddis in the evening. The full terrestrial box: hatch chart.
  • Fall (October–November): Baetis on grey days, and brown trout moving toward the spawn. BWO sizes and emergers: hatch chart.

For the whole river month by month, see the seasons guide and the hatch chart.

Regulations on this reach

  • Two wade-only stretches: Quake Lake down to Lyons Bridge, and Ennis Bridge down to Ennis Lake. No fishing from a boat in either.
  • The rest of the reach is open to fishing from a boat, and the Lyons-to-Ennis water is the standard float.
  • The boat restrictions and closures on this reach change, so check current Montana regulations before you go.

Reading the gauge

Readings come from USGS gauge 06038800 at Kirby Ranch, below Hebgen Dam. Typical summer flows run 900 to 1,400 CFS. Below about 1,100 CFS the wading gets comfortable; much above 1,400 and the banks fish better than the middle.

Live readings for all three gauges are on the river conditions page. New to flow data? See how to read Madison River flow data.

Frequently Asked Questions

When is the salmonfly hatch on the Upper Madison?

Usually late June into early July, though it shifts a week or more either way with runoff and water temperature. The hatch starts in the lower part of the reach and works upstream. See the salmonfly guide for how to track it.

Can you fish from a boat on the Upper Madison?

On most of it, yes. Two stretches are wade-only: Quake Lake to Lyons Bridge, and Ennis Bridge to Ennis Lake. The standard float is Lyons Bridge down toward Ennis.

What is a good flow for wading the Upper Madison?

Between about 800 and 1,100 CFS at Kirby the river is comfortable to wade. Higher than that and it gets pushy through the boulder runs. Felt soles or cleats and a wading staff are worth having regardless.
