Madison River Fishing Report - August 28, 2025

West Yellowstone – 315 CFS

Below Hebgen - 769 CFS

Kirby - 897 CFS

Varney - 1110 CFS 

A couple things to note:

  1. Hebgen Lake is roughly 4 feet from full pond and dropping due to diminished INFLOWS into Hebgen.  
  2. Flows below Hebgen have dropped in the last week to help conserve water in the lake.  
  3. With all the rain the past 24 hours, the Madison coming out of the Park has bumped up a little bit.  

BETWEEN THE LAKES

Its late August folks, better get after it cause summer is coming to close very fast.  Terrestrials (hoppers, beetles and ants) and caddis hatches are on the menu - be sure to have a variety of dry flies in your box.  With these cloudy days on hand, there will be a BWO hatch to some extent.  On some days you might just throw the entire box at the fish.  #12-16 chubbies, small hoppers, ants, a mix of BWO and caddis dries will be essential.  Searching the river with a single dry will be your best bet these days. As always, use the clues the river provides and take a moment before continuing to cover water.  Notice what’s going on around you, did caddis just start to hatch? There are not too many caddis around but the fish will definitely eat a properly drifted fly in the right water. However minimal, a small hatch will sometimes change the trout's behavior.  Sit down and watch the river, the menu is in front of you.  When in doubt, tie on an ant and cover water.  

Patterns of choice here recently have been the 101 Stone from Cat3 or Heames’ Jig Rubberlegs in #8 or #10 paired with a #14/16 Redneck or Olive hot-spot perdigon hung below. For caddis larva and pupa - the AZ Hares Ear, Shop Vac or Blow Torch are great choices.  Don't forget about the zebra midge - try sizing everything down and fishing two smaller thin profile nymphs with some spit shot. 

Swinging soft hackles is a good alternative to bobber fishing if you’re looking for some ways to switch things up from nymphing or casting dry flies.  Early morning, like sunrise, or late evening streamer fishing can be productive right now as well. The Sparkle Minnow, BFE or Bouface Leech patterns are tried and true for fishing early mornings or late evenings on the Madison.  The dry-dropper rig is as effective option these days as anything. Hang any of the above nymphs two feet below a Chubby and run with it.

Patterns of choice are as follows - Chubbies of all sizes and colors (we like #14 and #10),  #14 Iron X Caddis, #14 Elk Hair Caddis, tan X caddis, #12 & 14 Dark Missing Link, #16 Jojo Riffle Riser, #16 Yellow Missing Link, #16 PMD Sparkle Dun, #16 Jojo PMD, #14/16 Copenhaver Rusty or Cream Spinner, Jojo Rusty Spinner, #14/16 Fat Head Moth, #14 Corn Fed Moth

WADE SECTION

The Wade Section is a pretty chill place to cast a fly these days.  The weekends will bring on a few more anglers, but one can find plenty of room to cast a fly.  There are some caddis hatching, but not in great numbers.  Ants will continue to play a vital part in the trout's diet, as will hoppers once the rain subsides.  Typically, in late August and early Sept these rain showers bring out the honey ants.  We have yet to really see this, so keep that in mind when heading to the river this week! With these cloudy days on hand, there will be a BWO hatch to some extent. 

The fast, shallow water can hold the nicest fish of the day. Shallow riffles, soft pillows in front of boulders and edges close to the bank all are worth taking a good look at before moving upstream while wade fishing. You’ll notice more and more fish tucking tight up to the banks, so always make a cast upstream before you continue walking.  Cover water quickly, slow down when you find a fish and observe the type of water said fish came out of.  Then find more of it! 

A skilled nymph fisherman will pick up more fish with a bobber, stonefly, a caddis larva/pupa or mayfly nymph, more so than the dry fly angler right now.  Nymph patterns are the same as BTL. 

Dry fly patterns of choice right now are as follows - Chubbies of all sizes and colors (we like #14/16 and #10), #16 Chubbinator, #14 Iron X Caddis, #18 Elk Hair Caddis, tan X caddis, tan Iris Caddis,  #14 Dark Missing Link, #14 Jojo Riffle Riser, #14 Yellow Missing Link, #14 PMD Sparkle Dun, #16 Jojo PMD, #14/16 Copenhaver Spinner in Cream or Rusty, #14/16 Paranymph and Jonathan's PMD Klinkhammer. For moths - #12/14 Fat Head Moth, #14 Corn Fed Moth,#14 Elk Hair, #16 Ginger Chubbinator for the Moth (hint - cut of the trailing shuck). 

FLOAT SECTION

The rain this week is a welcome sight!  These cloudy over cast drizzly days make for solid fishing in the float stretch.  Flows have continued to drop in past weeks, and floats from Lyons to Pal, Windy to Mac or Mac to Varney are great floats.  On the bright sunny days, the river temps are heating up down here later in the day.  Pay attention the water temps and if the fishing slows way down, its probably not your fly or your drift. The tribs in the valley are flowing cold and likely at their lowest point in the season now.  Go early and get off early, the river temps after 4pm are def something to watch.  Its now time to size down your flies and fish caddis, smaller mayflies and definitely ant patterns.  The Tan Caddis, aka Hydropsyche, are still hatching, but not in great numbers.  Hoppers should be in the rotation, bring along and assortment of yellow, pink and tan. With these cloudy days on hand, there will be a BWO hatch to some extent. 

There is no time like the present to fish dry flies on the banks and around those sexy mid river gravel bars. #16 Elk Hair, #16 Compara Buzz, #14/16 Chubbies, #14/16 Chubbinators are great choices. A #12/14 Copenhaver rusty is a great choice as well as is Jojo's Rusty.  For hoppers  - Thunderthighs, Morrish Hopper, Sweetgrass Hopper, Pink Chubbies or Jojo's Nocturnal will bring fish to the surface. The bank water is holding fish, get your fly into the bank, as deep as you can with a good reach cast and you will be rewarded. Do it all day perfectly and you will understand why we love the Madison River so much. 

The dry/dropper fishing is producing and a great way to start the morning until the bugs begin to hit the water.  Think sparsely dressed, fast-sinking droppers with a big tungsten bead. We’ve got a number of gnarly, 3.8mm bead perdigons in the bins that’ll do the trick — namely the Tungsten Jig Splitcase PMD in #14/16, and Roza’s Pink Hare’s Ear Jig in #14/12, Olive Hotspots, Shop Vacs, Prince nymphs, Pheasant Tail, AZ Hare's Ear, and Redneck’s in #14/16 will also fool plenty of fish. 

If you haven't used the Fly Banjo combined with your favorite fly floatant, than you are truly missing out on the greatest little dry fly secrets there is.  

Respect The Fish 

  1. Keep the fish wet at all times. 
  2. Get out of the boat for fish pictures, if you need one. Take those pics quickly and get them back in the water.  
  3. Release played out fish on the banks where they can safely recover. 
  4. Be cool to other boats and wade anglers. Give plenty of room to other anglers. 
  5. Drop anchor on or near the bank when you need to change flies or re-rig. Bouncing your anchor down the river is complete nonsense and frowned upon.
