About this file
This document package includes drawings and specifications for fish passage improvements at Bonneville Dam on the Columbia River. The drawings depict the design and construction of new bollards to be installed in the Lamprey Passage area, including dimensions, materials, and fabrication details. Modifications to the design remove the requirement to paint the interiors of the bollards. The related federal contract opportunity is a solicitation issued on April 26, 2023 by the U.S. Army Corps of Engineers Portland District. Solicitation number W9127N23R0006 seeks contractors to provide labor, materials, equipment and supervision to construct the new bollard system as designed.
