The Lower Deschutes is prime for  Salmonfly and Golden Stone hatch all over from Warm Springs to Maupin. Any day now and they will be pounding by the banks and under overhangs.  
We have a super good supply of big Foam Flies, Clarks Stones and Norm Woods Specials so get them while they are hot. 
PMD and Caddis are locally important and can sometimes be the preferred meal for fish at times, even with all the big stones around. 

Spawning activity is now and will be for the next 5 or 6 weeks. Don’t wade the redds! Familiarize yourself with a red and how to avoid it, and never wade through that area and avoid being a goober and don’t fish for spawning rainbows on the Lower D. 

Here is a cool YouTube video from Devin Olsen on the subject. https://www.youtube.com/watch?v=yVIol18qVM8
