The Lower Deschutes is staying consistently good, especially with nice afternoon and evening hatches of Pale Evening Duns and Caddis. 
There are a lot of PED Spinners earlier in the evening and with that comes some great dry fly action you might not expect on a hot day. When that sun pokes behind canyon walls and the shade hits the water it is likely the hatches of PED’s and 2 or 3 caddis species overlapping in dry fly goodness. OR, swing a soft hackle, OR nymph a Tan X Caddis with a tiny split shot 12 inches up the tippet, OR upstream nymph an Silvey’s Primetime Pupa with a NZ Wool Indicator. Mix Black and White Wool to make your indicator bundle and be able to see it in the shade. 
Nymphing is amazing. Our guy Aaron (aka Trout Dirty) just spent 6 days on the river from Trout Creek to Harpham and if you know how AA-Ron got his nickname it is because he is a “dirty” nympher and one of the best with a Perdigon and a Jig.
