Missouri River Fishing Report: April 29, 2026

Summary

The Missouri is settling into a textbook spring rhythm, and the fish picture has flipped from post-spawn sluggish to actively eating. BWOs are the headline hatch on a daily mid-afternoon window, with midges all day and March Browns and caddis building. Craig Bridge is open again, so float logistics are back to normal.

At a glance: ~3,060 to 3,210 CFS at Holter | Clear, tailwater normal | 46 to 48°F, touching 50°F midday | Warming, highs 60s to 70s, lows 30s to 40s | BWOs daily, midges all day, March Browns and caddis starting

The Missouri is settling into a textbook spring rhythm. Flows are sitting in the 3,060 to 3,210 CFS range out of Holter (Headhunters at 3,210, Cross Currents at 3,200, Trout Shop at 3,060), water temp has climbed to 46 to 48 °F with midday spikes already touching 50 °F, and clarity is the usual tailwater clear. The week ahead looks warmer, daytime highs in the 60s and 70s, overnight lows in the 30s and 40s, with rain showers possible. After last week's brief cold-front pause, that warming pattern should keep the spring fishing window open and accelerate the hatch progression.

The fish picture has flipped from "post-spawn sluggish" to "actively eating." Rainbows have returned to the Missouri from the tributaries and are joining the browns in the feed lanes. Browns are aggressive on streamers and looking up on dries when conditions are calm. With the bridge open, anglers are spreading out across the canyon and below, Dam to Craig, Craig to Mid, and the runs down to Cascade are all in play.

BWOs are the headline hatch and are happening daily, often kicking off around 2 PM and running close to 6, with the brightest sunny days pushing the hatch later toward evening. Midges are going strong all day, Headhunters notes "Mini Midge 22 to infinite", and are most reliable in the slower seams. March Browns are up in the canyon and down to Cascade, with the Trout Shop calling out adult activity layered into the BWO window in the lower canyon. Caddis are starting to appear in the same water, caddis pupa droppers are already a great choice and the Trout Shop reports several big browns came on caddis yesterday.

Headhunters made a useful technical point worth carrying forward this week: on the Missouri, the angler who can deliver a slack-line presentation at the fly end of the leader, with short repeated drifts, will out-fish the angler who values pinpoint placement over drift quality. Adding line at the rod tip end exacerbates the issue. Good drifts near fish beat perfect placement on a tight line; the former wins the war, the latter wins a couple of battles.

Boat-traffic etiquette matters. Headhunters is calling out the need for wide berth on a low-water river, give wade anglers and parked boats plenty of space when floating. Ten-mile floats reward patience over crowding.

Best techniques

• Nymphing is the bread and butter. Cross Currents's specific protocol: deep in the morning (6 to 7 ft) with BWO and sow patterns; transition shallower (3 to 5 ft) in the afternoon as fish key on emerging bugs in the upper column. Headhunters confirms: nymphing is good, "not great", and Euro perdigon style is in favor on the low water.
• Dry-fly window is open in the BWO hatch from roughly 2 to 6 PM. Use a 9-ft leader minimum with 4X or 5X tippet to the bug, and prioritize a clean drag-free drift. Cripples, duns, emergers, and spinners are all in play depending on the day, and some days, none of the above. Stay willing to switch.
• Emerger or soft hackle just under the surface is the move when BWOs are emerging but you can't see noses, softie behind a small leech or minnow covers water and pulls grabs.
• Dry-dropper with a Skwala Chubby or larger mayfly dry up top, suspending a nymph below, clean play in skinny water with fish in the slow-to-medium soft seams transitioning to the harder seams off the bank.
• Streamer and swing is variable, one day great, the next slower. Headhunters reports occasional excellent days; Cross Currents has the bite trending up as the rainbows come awake post-spawn. Trout Shop notes streamers are especially effective on cloudy days. Wolf Creek Angler's Jason Orzechowski calls the Sculpin Sparkle Minnow the most productive streamer in his box, hands down, if you could only have one. Target drop-offs and mid-river buckets.
• Slack-line presentation at the fly end of the line is the single biggest skill upgrade right now per Headhunters, short repeated drifts beat single long drifts, and slack at the fly end (not the rod tip) is what opens the rise.

Hatches and flies.

BWO (Baetis): Nymphs: Green Machine, Two Bit Hooker, Two Hot Baetis, Psycho May (Olive), Mosason, BWO Magic Fly, Tungsten Tailwater Tiny, Crust Nymph, Black IPT, Micro May, Tung Jig PT, Tung Jig Hare's Ear, Frenchie, Blow Torch, Olive Crack Back Bullet, Olive Perdigon, Brown Perdigon, Purple Weight Fly. Emergers / Cripples: Sprout Baetis, Last Chance Cripple, Flash Cripple, Film Critic, BWO Hatchback. Dries: Pederson's 401K Baetis, Adams, Purple Haze, Olive Haze, Purple Para Wulff, Royal Wulff, Sparkle Flag, Split Flag, Brianne Dun, Hi-Vis BWO Spinner, BWO Guide Winna Spinna, CDC Para Spinner

Midge (Chironomidae): Nymphs / Pupae / Larvae: Zebra Midge (purple, olive tungsten, black mirage variants), Mercury Midge, Tufted Zebra, Midge Larva. Adults / Clusters: Griffith's Gnat, Cluster Midge, Adams Midge Cluster, Grizzly Midge Cluster, Black Midge, Harrop's Hanging Midge

March Brown: March Brown Nymph in #12 to 14 over a #18 BWO nymph is a productive stack right now. Trout Shop reports adult activity layering into the BWO window. Surface options include March Brown Parachute and Ms. Tickle Cripple March Brown when fish are keying on cripples

Caddis: Caddis pupa as the dropper has already produced fish in the canyon, Trout Shop reports several large browns took caddis yesterday. Cornfed Caddis is the surface pattern of choice as adults start showing, with Hi-Vis Spent Caddis for spent-wing presentations and Jeb Caddis in the rotation as well. Translucent Emerger in #14 is working sub-surface on the rising-but-not-eating fish

Sows & scuds: The Missouri's bread and butter. Pill Popper, TFP Skurp, UV Yum Yum, Soft Hackle Ray (pink, orange, or red bead), Pink Bead Tungsten Epoxy Back Sow, Tailwater Sow (natural grey and rainbow). Headhunters: "Mostly sows and pheasant tail mayfly style nymphs." Cross Currents: sows in the morning deep rig

Worms: Wire Worm picks off opportunistic feeders on bumpier flows and after rain

Soft Hackles: #12 to 14 Soft Hackle PT for the larger mayflies; Translucent Emerger #14 for caddis. BWO softies behind a leech or smaller minnow are a good way to cover water on the swing

Streamers: Flashy: Kreelex, Sparkle Minnow (Sculpin), Lil' Kim. White / smolt: Skiddish Smolt, white Sex Dungeon (big-white variant, go bold on cloudy days). Dark / leechy / sculpin: Sex Dungeon, Mini-Dungeon, Micro Peanut Envy, Mini Montana Intruder, Mini Sculpin, Bam Bam, Thin Mint, Heisenberg, Sparkle Bugger, Black Bugger, Peacock Bugger, Trout Spey Bugger, Gamechanger

Outlook. Warmer week ahead with showers possible, daytime highs in the 60s and 70s, overnight lows in the 30s and 40s. Flows should hold in the 3,060 to 3,210 CFS band. The BWO window should stretch through the week, and the March Brown and caddis pictures should both build meaningfully. Trout Shop hints PMDs typically arrive in mid-May based on last year, keep an eye out toward the back end of the month. As more rainbows finish the spawn the hungry-fish bite gets tighter. Streamer odds improve on cloudy days; dry-fly odds stay strong on calm afternoons regardless of cloud cover.
