It's mostly been small midge patterns tricking all the fish but the caddis are getting ready to hatch and there's some fish eating caddis nymphs pretty good too. Haven't heard anything about streamers and just a couple good dry fly reports here and there. Patterns to go with include Fox's poopah, buckskin caddis, Nori's caddis, zebra midge, flashback emerger, san juan worm, copper john, silver streak, rainbow warrior, mercury midge and mercer's midgeling. The Rosachi sectin in Nevada is also fishing pretty well, same patterns as up above and a lot less pressure.
