While we were lucky enough to get into the 70s and 80s for a while last week, the water warmed and we had some good dry fly fishing on the Upper. With our cool off, however, water temps have dropped from low 50s to about 39 degrees, meaning it's all subsurface now. The West Fork is pushing a lot of dirt, and flows have risen considerably, but have stabilized for now. Most of the time we flee from dirty water, but in the case of the Madison, embrace it.
