This Week's Weather Forecast in the Valley

Upper Madison
Conditions on the Madison have just continued to get better. Bite windows are opening up to span pretty much the entire day, and fish are much less picky about their meals. I drove through the valley on Wednesday and the amount of baetis that coated my front bumper was shocking, so the dry fly fishing oppurtunities have by no means waned.
Aside from smaller mayflies, larger attractors like Chubby Chernobyls have been getting a good amount of hits! A dry dropper setup is a great option, especially as this sun persists for the next few days. As far as nymphs go, fish have been go for a much wider span of flies; baetis, perdigons, and general emergers are all working quite well these days.

Dry Flies - Chubby Chernobyl, Purple Haze, Tilt Wing BWO, Trina's Hopper
Nymphs - Magic Fly BWO, Lightning Bug, Split Case, Olive Hotspot
