Best Time Window
- 6 AM - 9 AM: Prime caddis dry fly and soft hackle window before the sun hits the water and fish go deep.
- 10 AM - 1 PM: PMD nymph and emerger action in deeper runs and riffles; watch for rising fish in slower water.
- 5 PM - Dark: Terrestrial and evening caddis window along shaded banks; midge fishing picks up as light fades.
Guide's Tip
From the benchWith the Weber running low and gin-clear at 78.3 CFS, your approach matters as much as your fly selection. Stay low, move slowly, and keep your shadow off the water — these fish will spook at 30 feet in these conditions. Target the deeper seams and pool heads with nymphs in the morning, then transition to terrestrials and dry caddis patterns along grassy banks as the sun climbs. If afternoon thunderstorms roll in after noon as forecast, expect a brief surface feeding flurry — have a Parachute BWO or Corn-fed Caddis ready to go on a 6X leader.
