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.

Written by the app's rules engine from the calendar, the gauge record and the snowpack, not by hand, so it says only what the data says. The weather for the week comes with the app.
