Lower Madison River Fishing Report

Posted by: Toby SwankCurrent Conditions
The Lower Madison River is back on the drop, approaching 2000 cfs and fishing well as of today and yesterday. Sure, there's been some "weather" but it's nice to have a good option for a day of fly fishing near Bozeman this time of year.
It’s worth paying close attention to flows this time of year as conditions and the fishing “quality” change quickly with sudden increases. Expect dirty water around the mouths of the tributaries like Cherry and Elk Creek following heavy rains, this time of year. Dam releases have been increasing and are expected to continue rising with the rains forecasted for the rest of the week.
Nymphing is the best bet with crayfish, stonefly, and san juan worm setups under a strike indicator with added weight.
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 is NOAA's Norris Hill weather station. If it's really blowing there, it's likely 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.
