Phase 2 Wave Modifications Update - January 2025

Map
Guide to Phase 1 and Phase 2 Whitewater Park Features

The Boise Parks and Recreation Department is working closely with engineering partners to complete planned maintenance to the Phase 2 adjustable wave feature and Drop Structure 1 at the J.A. and Kathryn Albertson Family Foundation Boise Whitewater Park. Design modifications being constructed this winter (2025) are aimed at reducing the need for monitored operation of the Phase 2 adjustable wave feature, if possible.

In addition, these modifications will help improve flow operation flexibility at Drop Structure 1. All planned modifications are expected to be completed in the spring of 2025. Visitors to Esther Simplot Park will encounter some pathway closures for equipment staging on the eastern edge of the Boise Whitewater Park adjacent to Phase 2. Closures and any corresponding detours are signed.

The department’s goal is to create a unique and engaging recreational experience for all users. The Phase 2 adjustable wave is an expert-only feature, and the goal of this planned maintenance is to address the current instability and intensity of the wave. Our engineering partners have created a plan for adjustments to the Phase 2 wave that seek to meet operational and maintenance goals and enhance a fun and challenging in-river feature for river recreationists. Following feedback gathered from users at a community open house hosted in the fall of 2023, our team has spent the last year working through the permitting process and finalizing designs. Please read the updated Boise Whitewater Park Phase 2 FAQ to learn more about planned design modifications and what users can expect in the coming years.
