The Lower Deschutes has been good this week with good caddis hatches and Pale Evening Duns and PMD’s. Don’t forget the spinners of both mayflies with PED spinners often showing up in the eddies in the mid-day, and PMD spinners usually at dusk or early AM. I remember a time on the Lower D, fishing a riffle about 9 am and suddenly a massive wave of rusty spinners hovered over the riffle, and started dropping to the surface to lay eggs. It was one of the coolest 30 minutes dry fly sessions I can remember on the Deschutes. 
There are some amazing nymphing opportunities on the Deschutes and I want to remind you that they won’t all be in deeper waters. Look for fish in the weedy edges, shallow bars and seams where caddis pupa funnel through before hatching. 
Stonefly Nymphs, TJ Hookers, Perdigons, Frenchie’s, Soft Hackle or Flashback PT, Amber Psycho Prince and Red Copper Johns are favorites to euro nymph, dry dropper style or indicator fishing. 
Don’t forget about that good steelhead run coming up. Maybe right now with the heat I’d let the fish be, get them settled and start thinking about some great Fall days that are not actually that far
