Locations come from the source report. A gauge reference does not establish where every fishing observation was made. Hatches and fly recommendations belong to their individual report.
Silver Creek Outfitters
Cooler temperatures are increasing fish feeding activity ahead of winter, with Baetis continuing to hatch over the next few weeks. Leaf fall can make drifting difficult, but fish can still see the fly; dry-dropper or targeting rising fish recommended.
Hatches in this report: Baetis.
Silver Creek Outfitters
Baetis hatches are most active midday until the sun leaves the water. Use a long leader with a small high-vis Baetis pattern for rising fish, or a dry-dropper rig when no risers are visible; euro nymphing is also effective.
Hatches in this report: Baetis.
Silver Creek Outfitters
Good fishing with cooler water temps triggering Baetis hatches that produce feeding on both nymphs and dries. Low, clear water conditions require stealthy approaches as fish are spread across shallow tailouts, riffles, and seams.
Reported water clarity: clear
Hatches in this report: Baetis, Caddis.
Silver Creek Outfitters
Fishing has been good with cooler water temps triggering a Baetis hatch as the day warms; fish are spread across shallow tailouts and riffles in low, clear water. Stealth is essential when approaching runs.
Reported water clarity: clear
Hatches in this report: Baetis, Caddis.
Silver Creek Outfitters
Hecuba (Red Quill) hatches are occurring throughout the river with trout actively keying on them. Afternoon Baetis size 20, flying ants, and small cream crane flies also present; best approach is a high-floating dry with a small trailing nymph.
Hatches in this report: Hecuba (Red Quill), Baetis, Flying Ants, Crane Fly.
Silver Creek Outfitters
Low and clear water requires stealthy approach and accurate first presentations. Red Quills expected in cooler mornings alongside Baetis, Tricos, flying ants, caddis, and small crane flies.
Reported water clarity: clear
Hatches in this report: Red Quills, Baetis, Tricos, Caddis.
Silver Creek Outfitters
Water is very low and clear, requiring stealthy approaches; fish may be found in shallow oxygenated riffles above deeper runs. Morning hatches include Red Quill, Baetis, Tricos, flying ants, caddis, and small crane flies; hoppers are sparse but productive.
Reported water clarity: clear
Hatches in this report: Red Quill, Baetis, Tricos, Caddis.
Silver Creek Outfitters
The river is very low but fishing has improved with cooler water temperatures. Larger fish are spooky, so stealthy approaches and covering ground to find less-pressured water are recommended.
Reported water clarity: clear
Hatches in this report: Trico, Baetis, Spruce Moth, Crane Fly.
Silver Creek Outfitters
Red Quills (Hecuba) hatch is on — the last big mayfly hatch of the year — along with fall Baetis; fish are moving into tailouts and shallow riffles. Hoppers, ants, and nymphs trailed behind dry flies are also productive.
Reported location: tailouts and shallow riffles
Hatches in this report: Red Quill (Hecuba), Baetis.
Silver Creek Outfitters
Low water requires attention to water temperatures especially on the lower river, but cooler conditions are on the way. Multiple hatches including Tricos, Baetis, caddis, and PMDs are present, and the season-ending Hecuba hatch is approaching.
Reported location: lower river
Hatches in this report: Tricos, Baetis, PMD, Hecuba.
