Micro caddis hatch is strong from 9am to 1pm, and has lots of 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 very good.
Midges and BWO are showing from 8-10am, followed by the PMD hatch. On any given day, the PMD hatch can be excellent, with fish working the dries consistently. When the action subsides, around 2 pm, go to nymphs or streamers on a sinktip or Stillwater sinking lines. Fish from Cal tout to Zug Bug Alley, the trout have spread out nicely. PMD nymph - Hunchback PT, poxyback PMD, Burk's HB infrequens, Mercer's micro mayfly beadhead olive biot.
