Looks like Henry’s Lake Outlet part of the river is now diminishing as a quality fishery for the year. That’s because flow out of Henry’s Lake has dropped meaning shallower and warming water. This will move fish downstream to the Henry’s Fork. For the near future you can find them in the Tubs area above Mack’s Inn. Try streamer patterns. For the rest of the river presenting terrestrial patterns is the best way to fishing success.
