Lower Madison River Fishing Report

Current Conditions

Pretty great weather window this weekend and upcoming week on the Lower Madison River. This weekend is the coldest days with temps in the forties. Mid next week is calling for days in the high Sixties! With this great weather you can really pick your poison, nymphing will be hot as well as the streamer game. If we get a calm cloudy afternoon the Midges should pop.

Set up your favorite nymphing rod with a red Worm or a Balanced Leech followed by a small dark Perdigon, Zebra Midge, or Pheasant Tail. We are still finding the slower water to be most productive. This time of year can be great for stripping or swinging streamers. Keep your fly selection on the smaller side. A few favorite spring streamer patterns are Mini Loop Sculpins, Sparkle Minnows, and Skiddish Smolts.

Conditions are difficult to predict this time of year as it can be calm, here in Bozeman and ripping windy out there. One tool we use isNOAA's Norris Hill weather station. If its's really blowing there, its likley blowing pretty good out on the lower as well - but that isn't always the case as that station is located at the top of Norris Pass. It's worth checking out though so that you can come up with a plan B if it turns out to be too windy once you hit Black's Ford.
