Henry’s Fork, August 15th, 2020

If you fish the river below Ashton Dam during daytime, why not just go for a swim.  In Island Park terrestrial insects are just as abundant as on the lower river. But with cooler water fish are more active in taking them. They seem to like small (#18) rusty spinners, too. Tricos should be showing in significant numbers soon. Two rig nymphs (big pattern trailed by a small one) are working in Box Canyon.  Water is dropping and warming in the Flat Ranch portion. This means larger fish there will be moving downstream.
