Emerging PMDs and their spinner falls are providing action on the upper river and brown drakes are still emerging during evenings on the river from Wood Rd 16 up to the Osborne Bridge. Select locations within can become somewhat crowded. Flavs are coming on, too. Nymphing is the best way for action in Box Canyon. The lower river, mainly below Ashton Dam, is warming to the point that choosing another location to fish is worth considering. With summer coming on and accompanying low water, looks like mid-day fishing may not pick up until September. That means fruitful lower river fishing visits will take place during early morning and evening hours.
