About this file
This document package includes engineering drawings and a related federal solicitation. The drawings show modifications to the existing lifting beam extension arms for the fishway entrances at the north and south ends of The Dalles Lock and Dam. The modifications include adding steel cover plates with attachment hardware to the extension arms. The solicitation was issued on April 28, 2023 by the Department of the Army Corps of Engineers Portland District for a firm fixed price contract to perform the work detailed in the drawings. The solicitation number is W9127N23R0007 and is titled "TDA Fish Accords Lamprey The Dalles." Responses were due by the date of issuance. Award of the contract is anticipated to take place shortly thereafter so that the modification work can be completed.
