Madison River Fishing Report, May 16, 2026

Summary

The Madison is clear with good early-season flows, Hebgen steady at 665 cfs and tributary creeks driving most of the day-to-day variation. Nymphing is the primary method, a midge drift up high and stonefly nymphs and worms trailing BWO and caddis nymphs in the float. Caddis are hatching early on the lower stretches, which could set up an unusually good Mother's Day window on the Upper.

At a glance: Hebgen Dam 665 cfs (steady; no significant change anticipated until mid to late June barring biblical precip) | Kirby 788 cfs | Varney 960 cfs | Water clear, good early-season flows; Ennis Lake ice-free | Fluctuation source tributary creeks rather than dam releases, fishable conditions top to bottom for the foreseeable future

Upper Madison (Hebgen down through Raynolds and Three Dollar): fishing well, the river has been behaving more like late April and early May since mid-February. Most action is coming out of slower seams, deeper runs, and shelfy pockets where the bottom drops suddenly. The wade stretch has been all about the midge drift for most of the year. BWOs were slow to show up around Raynolds and Three Dollar relative to the mid-to-lower river but have started to appear over the last week or so.

Valley Garden through Raynolds Pass (MRFC's beat): consistently good. Nymph rigs are producing best with a mix of Pat's Rubber Legs, midges, and worms. On cloudy afternoons, fish are looking up for midges, don't be afraid to throw a dry.

Float stretch (Varney to Ennis Lake): a bit more consistent on larger patterns, stonefly nymphs and worms trailing BWO and caddis nymphs. The bite has been coming on around 9:30 to 10:00 each day rather than at first light. Notably, caddis have been hatching on the lower stretches over the past week, earlier than usual. If the pattern holds, this could set up an unusually good Mother's Day caddis on the Upper Madison.

Between-the-Lakes and Quake: streamer fishing in the float stretch has been slow over the last month; the better streamer work has been on foot from Ennis Bridge to the Lake or from Quake down to Lyons.

Spawning note: Spawning redds throughout the river. Both shops flag active spawning trout. Walk in front of cleared gravel rather than behind (eggs end up 3 to 10 ft downstream of the spawning bed) and be deliberate about wading lanes and anchor drops.

Best techniques

• Nymphing (primary). Double-nymph rig under an indicator is the most productive setup for consistent numbers. Pat's-style stonefly plus midge or worm trailer is the workhorse combo on the Upper; stonefly nymph plus BWO or caddis-nymph trailer is the pattern on the float stretch.
• Midge drift (wade). Zebra-style midges, jujubees, and small dips in a tandem rig, the staple for the Upper wade stretch year-round.
• Dries (situational). Cloudy afternoons bring midges to the surface; BWOs are starting to ride the surface film at Raynolds and Three Dollar. Watch for "little dark sailboats" and switch over.
• Streamers (improving). Slow on the float stretch, better on foot. Nymph small streamers (Zonker / Llama profiles in natural, olive, black) right in their face when fish refuse to chase. Expect strip-and-eat fishing to wake up as water temps climb into the high 40s and low 50s.

Hatches

The Fly Box

Nymphs: Pat's Rubber Legs, Zebra Midge, Three Dollar Dip, Juju Baetis, Olive Hot Spots, Barr's Emergers, Spanish Bullet, Olsen's Hare's Ear Blowtorch

Dries: Antonio's Adult BWO, Mini Hot Mayfly, Johnson's Mimic May BWO, Parachute Adams, X-Caddis

Streamers: Zonker, Barely Legals, Mini Dungeons, Peanut Envys, Double Screamers, Jiggy Pine Leech, Lil' Kim, Woolly Bugger, Sparring Partner

Midges (Upper wade, all year): Zebra Midge, Jujubee Midge, Three Dollar Dip, and assorted midge larva / pupa patterns.

BWOs (mid-to-lower river, starting at Raynolds and Three Dollar): nymph and emerger stage, Tungsten Redneck, Juju Baetis, Kelly's BWO Nymph, Dark BPs, Olive Hot Spots, Barr's Emergers. Adult/dun stage, Antonio's Adult BWO, Mini Hot Mayfly (Black), Mini Hot Mayfly (Garcia Yellow), Johnson's Mimic May BWO, Parachute Adams.

Stonefly nymphs (cover water, float stretch): Pat's Rubber Legs in small sizes, also doubles as a search pattern when the small stuff isn't producing.

Caddis (lower stretches, hatching early this year): no specific named patterns flagged yet by either shop, expect the standard caddis-nymph and X-Caddis menu to come on if the early hatch holds.

Mayfly / hare's ear nymph workhorses (MRFC's float-rig list): BH Pheasant Tail, Spanish Bullet French, Olsen's Hare's Ear Blowtorch.

Streamers (foot, Ennis Bridge to Lake / Quake to Lyons): smaller baitfish and sculpin profiles, Barely Legals, Mini Dungeons, thin articulated patterns like Peanut Envys and Double Screamers. Float-stretch nymphing menu: Zonkers and Dalai Lamas in natural, olive, and black.

MRFC streamer rotation: Jiggy Pine Leech (Black), Lil' Kim (Silver), Woolly Bugger (Black), Sparring Partner (Brown Trout).

Outlook. Flows should stay stable into mid to late June barring a major precipitation event. Tributary input will drive day-to-day fluctuation but the river is expected to remain fishable top to bottom. Streamer bite should pick up as water temps push into the high 40s and low 50s. If the early caddis hatch on the lower river holds, Mother's Day weekend (already past) and the next two weeks could deliver an unusually good caddis window on the Upper.
