Seeing some PMDs and caddis just about everyday.

Conditions

Above Lava Hot Springs, the Portneuf is in excellent shape with PMDs and caddis showing nearly daily. As of August 26, flows were running 42 cfs at Pocatello with a falling trend and stable forecast. Fish are rising to larger foam dries, so don't shy away from surface presentations. Consider hopper-dropper rigs to cover both the top and subsurface.

Techniques

  • Some fish already looking up and eating some larger foam dries as well.
  • Hopper dropper rig now until we get cold again is the best way to approach with vegetation growing up quick.
