Madison River Fishing Report: June 5, 2026

Summary

The release bump is underway: live USGS flows show Varney up about 34% in twelve days as Northwestern Energy starts matching inflow with Hebgen near full pool. That should put color back in the water and shift the bite from the small-bug game toward bigger profiles. Nymphing remains first chair, with stoneflies, worms, and cranefly larva moving up the priority list as flows build.

At a glance: Live flows (USGS, 6/5 a.m.) Hebgen outflow 494 cfs, Kirby 864 cfs, Varney 1,210 cfs, all up sharply from Slide Inn's 5/24 readings (449 / 684 / 904) | The story: the release bump Slide Inn forecast is underway, Varney up ~34% in twelve days as Northwestern Energy starts matching inflow with Hebgen near full pool (94.2% on 5/24) | Visibility ~3 ft+ with a green tinge on the Upper as of 5/24; expect more color now with rising flows and the West Fork and Indian Creek waking up

The big change since the last report is in the gauges, not the shop pages. Hebgen outflow has climbed from 449 to 494 cfs, Kirby from 684 to 864, and Varney from 904 to 1,210, the flow increase Slide Inn called for "in the next two to three weeks" is happening on schedule. That bump should put color back in the water and start shifting the bite from the small-bug game toward bigger profiles.

As of Slide Inn's 5/24 read, the Upper was fishing well with ~3 ft of green-tinged visibility, the wade stretch between Quake and Lyons was the productive zone, and the lower river by Ennis was rocky but floatable. The hatch story was a Baetis-and-midge show up top on cloudy days, with caddis and the first PMDs showing on the lower river near town. Slide Inn's two-week countdown to "things really getting going" lands right about now.

Flows note: Low-water boat hazards persist even as flows rise. As of the 5/24 report the river was floatable top to bottom in a hard boat but rocky through the Flats and from 8 Mile down to Town. Rising flows will ease this, but assume thin water over the bars until a shop confirms otherwise.

Best techniques

• Nymphing, still first chair, but upsize as flows build. The 5/24 playbook was small bugs up high (Quake to Lyons): BWO nymphs, caddis larva, small perdigons like the Spanish Bullet and assorted Dips. With the bump now underway, Slide Inn's own forecast says shift toward stonefly nymphs, worms, and cranefly larva, rubber legs and worm patterns were already the play down by Ennis. B to BB shot; dry-dropper on unpressured shallow banks if the bobber rig stalls.
• Dries, cloudy-day windows. BWOs up high; caddis and a few PMDs near town. Or commit to a small attractor like a Micro Chubby, throw at all the right places, and keep moving.
• Streamers, improving with the water. Small sculpin profiles have been the consistent producers: Peanut Envys, Mini Dungeons, Mini Whiteys, CH Barely Legals. The strip bite was decent-not-great at low clear flows, rising water and added color are exactly what it's been waiting for. MRFC's late-April note still rhymes: naturals in white and black.

Hatches and flies.

Midges: zebra midges, Three Dollar Dip (brown)

BWO nymphs and emergers: BH Pheasant Tail, Spanish Bullet (French), Olsen's Hare's Ear Blowtorch, small olive perdigons

BWO / mayfly dries: Antonio's Adult BWO, Mini Hot Mayfly (Black, Garcia Yellow), Parachute Adams, Johnson's Mimic May BWO

Caddis / PMDs (lower river): caddis on the sun breaks; PMDs building near town

Stones and worms (float / lower river): Pat's Rubber Legs (black), moving up the priority list as flows rise

Streamers: Jiggy Pine Leech (black), Lil' Kim (silver), Woolly Bugger (black), Sparring Partner (brown trout), Peanut Envy, Mini-Dungeon, Mini Whitey, Barely Legal

Outlook. The inflection is here. With Hebgen near full pool and outflow climbing, expect continued flow increases over the next week or two, more color in the water, and a transition to the big-bug game, stones, worms, cranefly larva subsurface, and a meaningfully better streamer bite. Salmonfly chatter usually starts within a few weeks of this flow pattern; watch for the next Slide Inn post to confirm timing. Below-average snowpack still means a Madison-friendly summer on the other side, less runoff blowout, longer fishable windows, but less push behind the river all season.
