Conditions

Fishable conditions persist on the Snake with more fish moving through the system after a slight flow drop to 14,800 cfs. Target tailouts, inside bends, softer edges, and current breaks where migrating steelhead and other species stack up. Floating lines, Skagit heads, and sink tips all have their place depending on water depth and position.

Techniques

  • Look for places where traveling fish can pause without fighting strongest current: inside bends, softer edges, tailouts and current breaks
  • Floating lines can cover shallower sections well, Skagit heads and sink tips give more control in deeper runs
