Live USGS gauge data is unavailable for today, but recent reports confirm flows on the Snake are dropping rapidly from runoff highs and water clarity is improving — the dry-fly window is cracking open right now. Overnight thunderstorms may add a touch of color by morning, but today's sunny skies and a high of 69°F will push clarity and fish activity in your favor.
Best Time Window
  • 7 AM - 10 AM: Early midge and BWO nymphing in the slower tailouts and inside bends before the stonefly action kicks off.
  • 10 AM - 3 PM: Prime golden stonefly and salmonfly window — work large nymphs and dry attractors tight to the banks under full sun.
  • 6 PM - 8 PM: Evening caddis and BWO spinner fall in the riffles; switch to a CDC caddis or parachute BWO as light fades.
Guide's Tip
From the benchWith flows dropping and clarity improving, the biggest mistake today is fishing the middle of the river — position yourself to cast tight to the grassy, undercut banks where golden stoneflies are migrating toward shore. Use a high-stick nymphing approach with a Pat's Rubber Legs in 3-4 feet of water, keeping your indicator just 18 inches above the fly so it doesn't drag in the variable current. When you see the first stonefly adults in the air around 10 AM, switch to a large foam dry and work the same bank-side water — the cutthroats will be looking up. After the overnight thunderstorms, check the water color at first light; if there's any added turbidity, lean on the Sculpzilla or Sparkle Minnow in the slower inside bends where fish stack up to avoid the push.
