The Beav is fishing excellent! Look for risers in the afternoons to BWO's. Streamer fishing is excellent at times. The river is hot!! Pipe to grass is probably most popular, but there is more water down low. It's all fishing great.
On the Big Hole we are having periods of very good fishing. It's still mostly streamers and nymphs but the skwalas are turning the dry fly bite on. Best bet is probably from Divide downstream.
