Fly fishing hatches in order of importance:

Midges are hatching all day long. At the moment they are small, midge pupa and larvae, size 22 to 24, olive,gray, black, chocolate, cream and of course red have been my best. The hatch is strongest from 10:30 to 2:00. The midges are clustering so try fishing a cluster to a single dry midge. Black has been best. There has been a small ant hatch, and the fish are starting to rise. Try fishing BWO’s from 1:00pm to about 5:00pm. The hatch is best on cloudy days. Dark or light gray, brown and olive have been the best colors in a size 20 and 22. Both dry and wet patterns. Bunny leeches and woolly buggers are working well either dead drifted or stripping them. Black, olive or cream have been best. Streamer fishing has been good. Small streamers size 10 or 12 in olive, black or brown.
