Middle Fork Willamette River

The Middle Fork Willamette River is one of several forks that unite to form the Willamette River in the western part of the U.S. state of Oregon. It is approximately 115 miles (185 km) long, draining an area of the Cascade Range southeast of Eugene, which is at the southern end of the Willamette Valley. From Wikipedia

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

Typical for the week over 10 years: 1,140 to 2,590 cfs. Running 757 cfs today, below 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.

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.
