There are some Salmonflies coming off now and that means it must be June! In the Powerhouse 2 Riffle, and downstream north of the Hwy 299 bridge, you should bring your favorite dry, the Rogue Stone, #8 Brown Chubby Chernobyls, and orange Stimulators can all be good choices. Don't forget the PMD and Baetis hatches. Make sure you have Adams or Parachute Adams in #18 & 20, Rusty Spinners, and a crippled PMD pattern like Zach's Milla Time May. On the Powerhouse 2 Riffle, there are lots of Caddis emerging too, Glossosoma and Hydrospyche, swinging a Soft Hackle, Bird's Nest or Poopah will get grabs towards dark. Also #16 - 18 Dark Missing Links, and the Lower Sac LaFontaine will work well. This is nature's melting pot of insects!
