If you are running Lower Blue at these levels, ~1400cfs, you should be fine. Upper Blue is kinda like wall rapid through the diversion dams, but the whole thing is like that and maybe its a little bigger in the second canyon of Upper Blue. Also, its too shallow to safely roll in the most difficult sections. So if you can run wall on Lower Blue without a sweat head for Upper Blue. Even at high flows Upper is only going to rate IV-, swims can be long but generally result in self rescue (not including boat) and very minor to no bang ups.
