From the benchWith 100% precipitation chance Sunday and temps hovering near 48°F, the BWO hatch is going to be exceptional — overcast, cool, and wet is exactly what Baetis need to pop. Focus your morning session on the deeper runs with a midge or stonefly nymph tight to the bottom, then transition to a BWO nymph-to-emerger setup as the hatch builds between 11 AM and 2 PM. If you see fish rising in the flat water behind main current seams, switch to the Parachute BWO or Barr's Flashback Emerger and dead-drift with a reach cast to avoid drag. Keep an eye on clarity — if the rain intensifies and you see the river color up, move to a streamer like the Sparkle Minnow Sculpin and work the soft water along the banks where big browns will push in to ambush prey.
