There will be some holdover rainbow trout. Oak Creek stays plenty
cold enough year round to support trout (at least in and above Sedona). The fish are not stocked in the winter due to lack of angler use from the cold and snow that comes from winter storms. They stock rainbows throughout the middle of summer at many locations throughout the canyon and even a few below Sedona. But for me the main draw is not the holdover stocked rainbows, but the wild brown trout. Oak Creek is considered blue ribbon and above Sedona there is a lot of water containing streambred browns, some of which grow quite large- 20"-24" large. There is even and catch and release only section.
The wild browns are EXTREMELY spooky and are very difficult to catch. But they are in there.
Check out the Oak Creek Angler's blog, he's caught some nice ones and there are lot of helpful tips in there.
