Cooler weather and clear water at 93 cfs are improving Silver Creek after summer doldrums. Tricos, Baetis, and Callibaetis should keep you busy through early September.
South Central Idaho
Covers Aug 26–Sep 2
The South Fork is holding at 814 cfs with prime 59-degree water—excellent wade fishing before flows drop in early September. Pinks, Baetis, caddis, and craneflies are working; Flavs, King Prince, and Rubber Legged Stones are solid patterns.
Upper Snake / Eastern Idaho
Covers Aug 5–12
The Big Lost is dropping into low-flow summer conditions and fishing despite angler pressure. Expect hatch activity through the morning and afternoon, with both dry-fly and nymph opportunities. Move frequently to find fish that haven't seen multiple casts.
