I had a Crane Prairie trip on Thursday with Mike and Dave and I jokingly told them at the Quinn River boat ramp that we wouldn’t catch a fish until 2. That was at 8:30, and the joke wasn’t far from the truth. We fish the Quinn, Rock Creek and Deschutes Channels and frankly found it to be quite slow until 1:30 when we got some fish on Red Worms, Rowley’s Olive Balanced Minnow and Red Hippie Stompers. That fly would have never been on my radar unless my friend Phil Fisher from Sunriver who I regard highly as a very proficient stillwater angler suggested it from the previous week when he found good success on it. 
My customer Micah who I trade info with from time to time was there 2 days before me and said he found okay fishing in the Cultus Channel on Black/Red Chironomids and Balanced Leeches. 
When I put on a large Red Ice Cream Cone for Dave we got an immediate eat on that. I will tell you the weather was just too bright and calm on Thursday. When we had a breeze the bite was better, when it was glassy, the bite was off.
