About this file
This document contains mechanical plans and general notes for a lamprey fish passage flume project at The Dalles Dam. The solicitation was issued on April 28, 2023 as solicitation number W9127N23R0007 by the Department of the Army Corps of Engineers Engineering District Portland. The plans call for fabricating flume components from 3/16 inch 5052-H34 aluminum sheet per ASTM B209. All components must be cold formed with minimum bend radii of 9/16 inch and cut without flames. Welds must be water tight and build up where needed to ensure smooth transitions. Supports may use stainless steel shims and must be coated with zinc molybdate prior to installation. The contractor must install flumes leak free with smooth surfaces and no snags.
