Snake River, Henry’™s Fork Confluence to Gem State Power Plant [SN1]


Many anglers flock to the Henrys Fork or the South Fork of the Snake River to catch big rainbows or native cutthroat, so that means fishing on the Snake River below the confluence of those rivers is not nearly as crowded and fish density is still quite high, outfitters report. “It’s great fishing,” says Michael Melville, owner of Melville Outfitters and Guides, based in Idaho Falls.
Melville is the only IOGA member who is licensed in this 25-mile reach between the confluence, north of Idaho Falls, and Gem Lake, south of Idaho Falls. He offers half-day fishing trips and full-day trips with lunch. Melville shuttles anglers to promising fishing holes by power boat, so he can work upstream or downstream. He’ll also drop people off at good spots so they can walk-and-wade fish.
Anglers catch big rainbows that move into the Snake River from the Henrys Fork, and they also catch big cutthroats from the South Fork. The Idaho Department of Fish and Game stocks the Snake River near Idaho Falls with catchable rainbows, so there’s plenty of rainbows to catch near Idaho Falls, Melville reports.
The confluence area also is home to lots of wildlife because of the lack of people. Melville also offers photography trips along this magnificent stretch of the Snake River. “You’ll see bald eagles, ospreys, owls, moose, elk, deer, you name it, they’re in there,” he says.
He also offers riverboat dining trips on the Snake River in Idaho Falls.
