Chad Allen's Tip of the Week

Boise River (In-Town) Flows are 300 at Glenwood, making the river very fishable! Small nymphs have been productive with good blue wing hatches in the afternoon. Small, natural colored streamers stripped slow or dead drifted have been catching some nicer fish as well South Fork Boise Tailwater The river is right at 300 below the dam. You can wade all over the whole thing. Nymphing a rubberlegs and a small nymph in the morning has been good. Midges have been hatching throughout the day with BWOs in the afternoon. Still seeing a few PMDs in the afternoon as well.

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.
