Main stem flows are now dropping to normal levels for this time of year. Consider that there are fewer trout in the main stem of the Snake River, but there are more large fish within than any other river around here. The best way to encounter these large fish is through float-fishing, but there are plenty of walk-in locations. Presenting streamers is the best technique, so have bright and somber patterns in large sizes within that fly box. Brown trout are moving to spawning areas, and rainbows will soon be following. Evenings and early mornings will be the best times to encounter the big fish.
