The best fishing on the lower river is from Warm River to Ashton, but that section is beginning to turn to early and late in the day for the best results. PMDs, a few goldens and flavs are present with caddis providing PM action. Don’t forget to pitch a steamer pattern around overhead cover as the sun sets. Crowds have thinned everywhere on the river. Much of that is because of the activity on the South Fork. On the upper river nymphing seems the most effective way to action in Box Canyon where recreationists will share the water. Further downstream at Last Chance and Harriman crowds have thinned a bit and mayfly hatches are off their peaks. AM and PM spinner falls provide good action with standard rusty spinner patterns being most effective. PMD and decreasing flav activity provide some daytime action with a variety of caddis taking over during PMs.
