Chad Allen's Tip of the Week

Boise River (In-Town) Flows are over 2,000 cfs. Wading is not safe and should not be attempted. South Fork Boise Tailwater The South Fork has been fishing great since the opener! Floating is the way to fish as flows continue to push water downstream at 1600 cfs. Big, buggy dries with a stonefly underneath has proved very effective. Heavy nymphs are the name of the game! Salmonflies will be starting soon!

Description: About Boise River

The Boise River consists of three separate forks that emerge from the Sawtooth Mountain Range. The confluence of the North and Middle forks join together near the town of Idaho City. The North fork is roughly 50 miles long. The Middle Fork is about a 52 mile stretch. Once joined together, the river continues its flow until it reaches Arrowrock Reservoir. The South Fork of the Boise River is a 101 mile stretch that rises from the Sawtooth National Forest, out of the Soldier and Smoky Mountains near Fairfield, Idaho. The South Fork flows into Arrowrock Reservoir and eventually joins the other sections at Arrowrock Dam. Past the dam, the river flows west adding in the Mores Creek tributary as it passes through Lucky Peak Dam and into the Boise area. Throughout the city of Boise, the river is lined with a 35 mile recreational and alternate transportation area known as The Boise Greenbelt. The Boise River then winds west toward northern Canyon County, where it eventually meets up with The Snake River at the Idaho-Oregon Border.
