Phase 2 Wave Modifications Update

Guide to Phase 1 and Phase 2 Whitewater Park Features

The Boise Parks and Recreation Department is working closely with engineering firm McMillen on planned updates to the Phase 2 adjustable wave feature (#6 on corresponding map) at the J.A. and Kathryn Albertson Family Foundation Boise Whitewater Park. Engineers are proposing design modifications that will support unmonitored operation of the Phase 2 adjustable wave feature and improve flow operation flexibility. The maintenance modifications are expected to be implemented over the winter, with the completion of all planned modifications expected in the spring of 2024.

Parks and Recreation’s goal is to create a reliable recreational experience for all users, so whitewater park wave operators will no longer need to host monitored sessions at the Phase 2 adjustable wave. The Phase 2 adjustable wave is currently an expert-only feature due to the power and intensity of the wave. McMillen engineers have created a plan for modifications to the Phase 2 wave that meet the city’s goals, while creating a fun and challenging in-river feature for river recreationists at a variety of flows.
