Yellow Dog Flyfishing's Tip of the Week

Dry fly fishing with Caddis has been good in the afternoons. Nymphing has been good and streamer fishing has been OK. Check the wind conditions prior to heading out. BWO's, March Browns, and Caddis have been spotted. You may find fish rising to these bugs in certain areas.

5-Day Outlook as of 5/4/26

The river is back on the rise after the warm weather. Pretty darn nice conditions all week but slightly cooler than last week. Fishing could be good as long as the river keeps some clarity.

Techniques & Tips as of 5/4/26

Nymphing with stonefly nymphs, worms, or perdigons will be the best bet. Fish your nymphs about 5 feet under your indicator with a split shot. Streamers will be another good option. If fish are rising a caddis or BWO dry will trick the rising trout.
