The lower river fishes best during daytime hours when two-nymph rigs are used, especially below Ashton Dam where the river is warmer than above. Not much dry fly action there during daytime unless you present hopper patterns close to the well vegetated banks. Best dry fly action is during evening caddis activity. Other than AM spinner falls the best fishing on the upper river is found by presenting such terrestrial patterns as ants, beetles and hoppers.
