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
Flows stable at 300 CFS, making conditions ideal for wade fishing. Baetis and midges are the primary hatches during the warmest parts of the day, with occasional October Caddis; nymphing effective when insect activity slows.
Hatches in this report: Baetis, Midge, October Caddis.
Silver Creek Outfitters
At 300-309 cfs wading is the preferred approach over boating. Nymphing is the most effective method but persistent dry fly anglers are also finding good action, especially in the afternoon when Baetis, Pinks, midges, caddis, crane flies, and flavs are present.
Hatches in this report: Baetis, Midge, Caddis, Crane Fly, Flavs.
Silver Creek Outfitters
Steady flows at 300 cfs with Pinks, Flavs, and Baetis hatching during the warmer parts of the day. Evening caddis hatch remains decent and worth fishing after the sun leaves the water.
Hatches in this report: Baetis, Flavs, Caddis, Chironomid.
Silver Creek Outfitters
Steady flows at 300-309 cfs with Pinks, Flavs, and Baetis hatching during the warmer parts of the day. Evening caddis hatch remains decent and is worth fishing after the sun leaves the water.
Hatches in this report: Pink Alberts, Flavs, Baetis, Caddis, Crane Fly.
Silver Creek Outfitters
Flows at 300 CFS make for ideal wade fishing conditions. Flavs and fall Baetis active during the day with strong evening caddis activity; hopper-dropper, deep nymphing, and Euro nymphing effective when bugs are scarce.
Hatches in this report: Flavs, Baetis, Crane Fly, Caddis.
Silver Creek Outfitters
Flows dropped and stabilizing around 300-329 CFS making it a wade fishing paradise; fall Baetis should be excellent along with a few PMDs (flavs) and caddis. Focus on soft seams next to quality holding water.
Hatches in this report: Baetis, Flavs, Caddis.
Silver Creek Outfitters
Flows at 600 cfs favor wading over floating. A few Flavs and Pink Alberts are hatching midday through early afternoon, with Baetis beginning to appear especially on cloudy days.
Hatches in this report: Flavs, Pink Alberts, Baetis.
Silver Creek Outfitters
Flows holding around 800 CFS with floating still possible; a few Flavs and Pink Alberts hatching midday through early afternoon, Baetis emerging especially on cloudy days, and caddis present in late afternoons as a good searching pattern with a nymph dropper.
Hatches in this report: Flavs, Pink Alberts, Baetis, Caddis.
Silver Creek Outfitters
Flows holding around 800 CFS with the floating season winding down as flows are expected to drop to 600 and then 300 CFS through September. Pinks, Baetis, caddis, craneflies, and terrestrials are all present.
Hatches in this report: Baetis, Cranefly.
Silver Creek Outfitters
Flows have dropped to 800 CFS (reported at 814 CFS). Hatch activity has been sparse, but Pink Alberts are present in the afternoon along with caddis early and late; hoppers are also turning fish.
Reported water clarity: clear
