In-Depth Fishing Report for The Snake River, Henry’s Fork, South Fork of the Snake, Portneuf River as well as surrounding lakes and still waters of Southeast Idaho
Snake Below American Falls Reservoir: Flows out of the dam are 12,500 and the reservoir is at 100%. This is normal flows for this time of year, flows may increase over the next few weeks as peak runoff occurs. The water clarity is incredible and the fish are happy. Streamer bite is on fire for BIG smallies and trout. Flashy clousers and perch flavored streamers are the ticket. Make sure you bring your sink tip and hold on. Nymphing stoneflies and leeches has also been hitting trout and bass.
South Fork Snake River : Fork Flows are at 10,900 CFS with the reservoir at 64% full. Water clarity and flow is perfect right now! Anglers are working riffles with nymphs (e.g., zebras and prince nymphs) and bullwhip worms with really good success. Streamers have also been moving fish. This is a perfect window to float the South Fork before the higher flows begin.
Henry’s Fork: BIG BUGS are Poppin! The lower river is seeing the Giant Salmonfly with folks catching fish on BIG Dries and Rubberleg droppers. Caddis action on the surface also. Swinging soft hackles is also successful. The Pteronarcys hatch will start working its way to the upper sections with the temperature increases expected later this week. Flows out of Box Canyon are ~700 and this is perfect for walk and wade or a float trip.
Still Water/Lakes: Hawkins, Chesterfield and Daniels are peaking right now and should defiantly be on your lake list. Balanced blue pills, scuds and leeches are the ticket. Damsel nymph patterns has been productive. Dont forget Chironomids! 24 mile reservoir is now fishing 🙂
Portneuf: Most sections are running real high and muddy. Your best shot would be streamers and worm and large nymph rigs on the upper sections closer to chesterfield.
Snake River By Tilden. Flows are up and the clarity isn’t great (~9800cfs). Be careful running these sections of tree snags and other debris. Fish deep and slow and you should find em. White and black streamers have been best
