Terrestrial insect season is going on up and down the river. Exceptions include AM trico mating-spinner falls and evening caddis activity. PMD activity is greatly diminished and speckled duns are important only on slow river reaches such as the Flat Ranch and Harriman State Park. When cloudy days arrive streamer fishing will be more effective during mid-day rather than just around first light and twilight. Tiny BWO activity on the lower river is several days away.
