  • Midgessizes 18 to 22
  • Small eggs and worms
  • Pheasant tail and zebra midge nymphsunder an indicator

Typical for the week over 8 years: 36 to 75 cfs. Running 362 cfs today, above that range. Flows are not forecast; check the gauge the day before.

Brown Trout are spawning (October to December). Stay off clean, light-coloured gravel in riffle tails and pool tailouts, and leave paired fish alone.

Brook Trout are spawning (September to November). Stay off clean, light-coloured gravel in riffle tails and pool tailouts, and leave paired fish alone.

Mountain Whitefish are spawning (October to December). The egg bite behind spawning whitefish is the best winter nymphing of the year: an egg pattern below the riffles.

  • Flows swing a lot this week most years. Carry both a heavy nymph rig and a dry-dropper and let the gauge decide.
  • Egg patterns in the runs below the spawning gravel, never on it.
