Techniques & Tips

Dry flies and nymphs should both be effective. Match what you see in the air with similar dries and nymphs. My 3X tippet recommendation is for fluorocarbon material.

If you are fishing small dries and the leader is sinking the fly, then you will need to go back to nylon tippet in 5X or 4X.

7-Day Forecast

At the river, there is no precipitation in the week ahead. At mid-elevations there are a couple days with a slight chance of thunderstorms, and with little snow remaining in the Wallowa the flow should continue its steady decline.
