Lower Madison River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Lower Madison River is a tough sell right now. The stretch from Madison Dam to the NorthWestern Energy powerhouse remains closed to fishing, and the river below the powerhouse to the Jefferson is under hoot owl restrictions, closing to fishing each day at 2 p.m. Warm water, daily pulse flows out of Ennis Dam, and heavy recreational traffic have made for challenging conditions.
A two-nymph rig with a crayfish attractor and a perdigon or zebra midge is still the most consistent approach. The changing flows make depth more important than changing flies, so adjust weight before switching patterns.
There are still a few fish willing to eat caddis or a hopper early, but the dry fly window has been short. Once the sun gets on the water, fish become much less active and recreational float traffic only makes things tougher.
There are better options around Bozeman right now. The Lower Madison is best left for an early morning if it's close by, while the Gallatin, Yellowstone, and Upper Madison continue to provide more consistent fishing.
