Water Flow Data

5-Day Outlook as of 4/8/26

The river is a bit dirty after the recent increase in flows. Pretty darn nice conditions expected all week. Fishing could be good as long as the river keeps some clarity.

Techniques & Tips as of 4/8/26

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. Fish are mostly in the slow moving (walking speed) water. Streamers will be another good option.
