AM and PM spinner falls and daytime terrestrial insects (particularly ants and hoppers) are providing most of the action on the upper river. So have patterns for these available. Are you fishing the river in Harriman State Park just before and after sunset? Don’t be shy about offering a hair mouse pattern along grassy banks especially if deeper water is nearby. Big Daddy may be waiting! In middle reaches of the river terrestrial insect and caddisfly life cycle patterns rule the effectiveness roost, particularly during PM hours. On the river below Ashton Dam warmer waters are present, so early in the day visits require spinner patterns, rusty and otherwise. Caddisfly and terrestrial insect patterns are appropriate for later in the day. Also be sure to have streamer patterns ready as sundown comes about.
