Last month, Otak’s Joshua Owens visited the Colorado Avenue Dam Safe Passage project site in Bend, Oregon, to inspect construction. This project will provide a passage over the existing dam via three channels, one for habitat, one for whitewater recreation, and a “safe passage” option for recreation without rapids. Joshua, a water resources engineer, visited the site with Jason Carey, principal river engineer at River Restoration, the Colorado-based firm that designed the whitewater and habitat channels. In Stage 2 of the project, water is diverted into the future habitat channel while the safe passage and whitewater channels are being constructed. The whitewater channel, which is being built first, will have four drops, each designed to provide a unique wave experience for kayakers and paddle boarders. Pneumatic bladders installed on the drops will be able to shape and fine-tune the waves. During the visit, boulders were selected and placed for drops two and three in the whitewater channel to ensure that they are built as designed.
