Hosmer Lake is good in the upper lake and channel. Damsels are getting more active, so both the nymphs and adults will be useful. Callibaetis nymphs and adults most days will be great. Have any other of my Homser dedicated found the “hatch” to be less prevalent this season? 
Traveling Sedges are out and a Goddard Caddis skittered on the surface is one of the great takes of your life. 
Leeches and Chironomids will be important, and think about stripping soft hackles on a Hover Line and also leeches and damsels and callibaetis nymphs stripped on the slow sinkers instead of just the bobber approach .
