Henry’s Fork, May 29th, 2021

The big stone fly hatch is spread out along much of the river. Some remain on the lower river which up to now has been crowded with drift boats, rafts, and walk-in anglers. Look for Box Canyon to host a big portion of it, but the Riverside area on down into Cardiac Canyon will hold a lot of these bugs.  Boats will be out ” en masse” in these water down to Hatchery Ford.  If you want to get away from them, try the Bear Gulch area, go to Mesa Falls State Park and walk upstream, or walk downstream from the Hatchery Ford area. Include caddis fly life cycle patterns in your fly box. Afternoon caddis hatches can be dense throughout the river, and fish can key on them even though the big stone flies are out.
