Lower Madison River Fishing Report
Current Lower Madison River Fishing Report
Updated 09/03/2026
Current Flow: ~ 1210 CFS below Ennis Dam
The Lower Madison has been fishing pretty well in the mornings as we start working our way into September. Keep in mind that the river is still under hoot-owl restrictions from the Warm Springs BLM boat ramp downstream to the confluence with the Jefferson River, so fishing needs to wrap up by 2 p.m. The cooler mornings have definitely helped, and the early part of the day continues to be the best window. Fish are still willing to look up, so keep an eye out for Blue-Winged Olives in the mornings. Hoppers, ants, and smaller attractor dries are also still worth fishing, making a hopper-dropper or attractor-dropper rig a great way to cover water.
The crayfish bite has started to pick back up, which is always a good sign on the Lower Madison heading toward fall. A crayfish or smaller rubber-leg pattern with baetis nymphs underneath has been a good setup. Lightning Bugs, Zebra Midges, Perdigons, and smaller caddis patterns are all still working well below the surface too. Focus on the deeper runs, buckets, weed edges, and areas with a little more current where fish have some cover. With the river still relatively clear, don't be afraid to drop down in fly size or lighten up the tippet a little if the fish start getting picky.
Streamer fishing is also becoming more worthwhile, especially early in the morning or when there is a little cloud cover. Small sculpin and baitfish patterns are good places to start, and even crayfish patterns swung, twitched, or lightly stripped through the deeper water can get some attention. The Lower is definitely starting to feel a little more like fall, but we're not completely out of the summer conditions yet. Get an early start, keep an eye on water temperatures as the day warms up, and take advantage of those cooler morning windows while we wait for more consistent fall weather.
