Micro caddis hatch is strong from 9am to 1pm, and trout on the surface. For best success, swing small emergers in the surface film. Some PMD's also hatching. Long fine leaders and stealth are needed to fool these wary rainbows and browns. Evening caddis hatch can also be good.
Fishing is good to very good.
BWO hatch starts midmorning, and is very strong on overcast days. PMD hatch follows around 11am. Trout are eating both the nymphs and dries. The key is to find the pods of the larger fish as you motor upstream, and fish for them later in the day. When the action subsides, around 2 pm, go to nymphs or streamers on a sinktip or Stillwater sinking lines.
