Lower Madison River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Lower Madison River has made a big turnaround and is fishing much better than it was a few weeks ago. Cooler nights have dropped water temperatures, and anglers are finding consistent action from the dam down through Bear Trap Canyon and into the lower river. One important change is that the hoot owl restrictions have been lifted, so the river is open all day again.
With the cooler weather and recent wind, nymphing has been the most dependable approach. San juan worms, Spanish bullets, Rainbow Warriors, and smaller zebra midges have all been fishing well. Crayfish patterns in natural or olive have also been a good choice, especially through the deeper runs and buckets. Lighter tippet has helped in the clearer water, and it's worth slowing down to make a few good drifts before changing flies.
The Lower is back to being a solid option around Bozeman. If the cooler weather sticks around, expect it to keep improving as September goes on.
