September 18, 2026

North-Central Idaho

Selway River

The Selway is running normal September flows with good access to productive water types. Nymphs and small streamers are your main play, with terrestrials productive during warmer windows.

620 cfs ↓

South Central Idaho

Silver Creek

Silver Creek is fishing well with active fall hatches and prime water temperatures. Flows are dropping but holding steady at 75 cfs.

75 cfs ↓

North-Central Idaho

Snake River, Hells Canyon Dam to Clearwater Confluence

Flows are normalizing at 13,100 cfs, making it a good time to move water and hunt traveling fish in traditional holding zones with lighter tackle.

Panhandle

Spokane River

Stellar fishing with excellent hatches of mahogany duns, fall BWOs, and October caddis. Flows are running 866 cfs at Post Falls.

September 17, 2026

Upper Snake / Eastern Idaho

South Fork Snake River

Fall conditions with cooler temperatures are establishing themselves on the South Fork, with slightly turbid upper water favoring streamers and clearer lower sections ideal for dun imitations.

Very low · 2,160 cfs

September 16, 2026

Upper Snake / Eastern Idaho

Big Lost River

Covers Sep 16–23

Low water is concentrating Big Lost River trout into prime holding zones where fall Baetis and caddis patterns should produce once fish settle in.

September 15, 2026

Upper Snake / Eastern Idaho

South Fork Snake River

The South Fork is running very low and falling, with good mahogany and BWO activity on overcast days. Fish nymphs and terrestrials early and during cloud cover.

Very low · 2,560 cfs

September 13, 2026

North-Central Idaho

Clearwater River

Early steelhead runs are on the Clearwater with modest numbers showing. Flows are dropping into comfortable range at 6,930 cfs and 55 degrees.

6,930 cfs ↓

September 12, 2026

North-Central Idaho

Clearwater River

Early steelhead are trickling in with low numbers and prime water temperatures. Flows have settled at above-normal levels, making swing water increasingly fishable.

10,400 cfs

South Central Idaho

Big Wood River

Covers Sep 16–23

Red Quills and Fall Baetis are active on the Big Wood, with fish feeding in tailouts and riffles but spooky to approach. Stable, low flows favor careful sight-casting through mid-September.

1.7 cfs

Salmon Region

Salmon River

Covers Sep 16–23

Stable flows and warming afternoon temps should bring steady October Caddis fishing through the week. Target riffles flowing into deep runs.

3,500 cfs ↓

South Central Idaho

Silver Creek

Covers Sep 16–23

Silver Creek's cooling water and stable flows set up solid mid-day through afternoon hatches over the next week, with Callibaetis, terrestrials, and October Caddis in the mix.

76 cfs

South Central Idaho

South Fork Boise River

Covers Sep 16–23

Flows have stabilized around 300 cfs, making the South Fork a wade-friendly proposition with excellent Fall Baetis activity and cool water temps of 56°F.

North-Central Idaho

North Fork Clearwater River

Route 255 and Hoodoo Pass have reopened, restoring full access to the North Fork Clearwater. Lightly fished water and transitional fall conditions make this a strong bet right now.

Panhandle

North Fork Coeur d'Alene River

Cooler weather and stable flows make for solid September fishing on the North Fork. Focus on caddis, terrestrials, and small emerging patterns.

258 cfs

Panhandle

Saint Joe River

The Saint Joe is fishing productively on both upper and lower sections as fall arrives, with a mix of terrestrials and emerging insects keeping fish engaged. Flows are stable around 436 cfs.

436 cfs

North-Central Idaho

Snake River, Hells Canyon Dam to Clearwater Confluence

Early steelhead season is running with sparse fish. Flows remain stable at 11,100 cfs at Anatone.

11,100 cfs

Panhandle

Spokane River

The lower Spokane is fishing well with stable flows and cooler temps. Upper valley sections are recovering but not yet productive.

859 cfs

Upper Snake / Eastern Idaho

Henry's Fork of the Snake River, Box Canyon to Riverside

Clear water and steady flows at 1,140 cfs favor sight-casting through the morning hatch, with Mahogany Duns and Blue-Winged Olives peaking midday before afternoon winds build.

1,140 cfs

North-Central Idaho

Kelly Creek

Kelly Creek is accessible again after a recent road closure. Summertime patterns still work, but fall transition hatches are starting to show.
