I heard from many reliable sources that that river fishes great that time of year. They have stocked a ton of fish and there are many beautiful wild trout in there as well. I have only been there once but it was in the middle of the winter and the water was roaring. The scenery is amazing. I am sure you guys will do very well! Slondeep says not to worry about high flows in the spring as long as they are stable. This looks like it might be the case given the prolonged high water on that river. But then again I don't know how they regulate the flow. Dave, likes to fish there in low water because its literally like shooting fish in a barrel he says. So no matter the conditions you will do well. I know there are two catch and release sections separated by a kill zone and all three fish well from what I hear.
