The Grannom caddis emergence appears to be over for the season. With the continued warm weather, the water temperatures are now into the low 50's and the hatches and fishing has taken off.The BWO hatch starting times are all over the place now, in some areas around 11:00-11:30 while other areas don't start until 1:00-2:00. This continues till around 3:00 and the dry fly fishing has taken off. This is the time to key on the riffles, ankle to knee deep. Along with the mayflies the caddis hatch is picking up and the craneflies are already showing up. Craneflies generally emerge mid to late morning but right now they're going into the early afternoon. If you're not familiar with them you can mistake them for PMDs, the back legs look like tails so look for the "knobby" head as they fly away. That of course includes midges all day long.

Those nice deep holes are pretty much empty except for the big backwaters, the fish seem to be holding there and feeding on midges. It's not just the water temperature that dictates fish activity. So far the water has remained clear but keep in mind that after rain or snow melt the river can be dirty below the Petroglyph parking (#9) from Horton Creek. If you're down below and it's dirty just move upstream until you find clean water. The old winter rule still applies, the colder the night before the further upstream you should start.
