Henry's Fork

Mayfly emergence events on the upper river are diminishing quickly with colder weather setting in. Soon that of BWOs will be the only one available. Almost on key flying ants are coming on to provide action from trout which seem to crave them. So add ant patterns to your terrestrial pattern roster when you venture to the Last Chance , the Harriman State Park reach, and the river around Hatchery Ford.
Fly Patterns to use:
Harrop’s CDC Water Wasp-Honey
Antonio’s Adult BWO
