Flows through the canyon from Hirschdale to Verdi are fine and running at  90cfs.   Fishing is OK in the mornings and into the afternoon.  Czech Nyping 16-20 Mayflies, PTs, Copper Johns and Beatis under a  rubber legs works well in the pocket water.  Dead drifting the same flies works in the runs, riffles and tailouts.  But get down to them.
High numbers are outweighing the size of the fish.  The big guys are a bit more rare than usual. 

Most Big fish have been caught on Clousers and buggers however the action has been slower.
