Conditions

The Snake is running stable at 12,900 cfs as of October 16, well below summer highs but still carrying good water. Fish are spread across multiple runs and holdover habitat is generous, so plan to cover different pieces of water rather than camping one spot. Conditions are clear with mild temperatures and no rain in the forecast, making for pleasant fall fishing.

Gauges

Techniques

  • Floating lines are useful in the shallower stuff, while sink-tips can help when the water gets deeper or faster
  • Look for spots where fish can travel without sitting in the strongest current. Softer inside edges, tailouts, current breaks and slower seams are all worth fishing
