Snake River Tributaries

The Snake River in Jackson Hole has fished very well over the past week. Afternoon showers have produced good mayfly hatches, in particular the Timpanoga Hecuba (Snake Drake) and Infrequens PMD. Both of these are large bugs, sizes #10-14. The Snake River Cutthroat pay attention when these morsels are about and the larger fish often prefer them over other available bugs. Hatches are best on cloudy, overcast days, but fish these flies anytime in all water types.

Our fall stonefly, Claasenia Sabulosa, is also present on all stretches of the river. This stonefly hatches predominately in the evening and overnight. The males do not have fully formed wings, so this is why you won’t see alot of these bugs flying around. The females do have wings and fly, typically after they have mated and are returning to the water to lay their eggs. Egg-laying flights have not begun yet, but look for them in the next week or so.

Fish Stonefly patterns in all water types, especially fast moving banks and runs. This bug is large enough to get Cutthroat to eat in big water. Remember to twitch your imitations as the males skitter across the water since they cannot fly.

Best Flies: #10-12 Parachute Adams or Hare’s Ear, #10-12 Ausable Wulff, #12 Snake Drake, #8-10 Water Walker (Tan, Golden, Pink/Red), #12 Lawson’s PMD Cripple



Best Flies for Snake River Tributaries

  • Fly: Parachute Adams
  • Size: #10-12
  • Details: The Parachute Adams is perhaps the most important and versatile of all dry flies. It is a must have dry fly. The white post gives the fly fisherman a focal reference point in all types of water. The pattern can be used as a mayfly or as a searching or attractor fly.

  • Fly: Ausable Wulff
  • Size: #10-12
  • Details: Tied as a full-bodied attractor pattern in the Wulff-style, this pattern is an excellent attractor pattern for western rivers. With the traditional upright and divided wings and light body coloration it is a good attractor pattern when the Green Drakes and Slate Drakes are on the water.

  • Fly: Lawson’s PMD Cripple
  • Size: #12
  • Details: “Cripple” patterns represent mayflies that are either just emerging or that got stuck in the shuck while emerging. In either case, the insect isn’t going anywhere soon. Trout recognize this vulnerable condition and feed eagerly on cripples when they see them.
