The main event here is big stoneflies hatching on the lower river. To be sure presenting big dries brings great returns, but it seems that every fly-fisher around, whether wading or boating, is on the lower river. This presence will soon happen on Box Canyon where nymphs are moving and such as rubber leg patterns are working well. Downstream from Riverside Campground would be a good location in the upcoming days to enjoy fish responding to the drifting big stoneflies. You might have to put up with boat traffic, but such will not be as concentrated as on the lower river or that which will happen soon in Box Canyon.
