One day there are a ton of bugs on the water and the next nothing. We have no idea why, but when it's on, it's on. Cloudy days coming up will help with all of this as will the cooler temps this week. Mahoganies and BWO's are out on the right days. Streamer fishing is picking up with the cooler water temps and the clouds. Olive/Gold and White/Gold are great color combo's for the Bitterroot. Nymphing PT's, Rubberlegs, Princes, Eggs and San Jauns is another good option.
