The lower D has the most prolific salmonfly hatch, but the middle should not be over looked just got to know where to go. I like to fish from Pelton Dam (Warm Springs) down, because it's closer to Bend. It can get really busy down there typically around Maupin because you get alot of Portlanders. There are some nice fish to be had. Last year in July I took a trip to the Yak and that was great too. The thing about the D is no fishing from a boat so best to keep an eye on the flows. I fish all of the D from the headwaters at Little Lava down. Each stretch is great and has a whole lot of character to it and species. Here's a great link to the whole Deschutes Basin to check the real time flows:

If you would like to know more about some particulars let me know.
