Yakima River Basin Integrated Plan Water Resource Management Plan update on technical and planning studies.
Fish passage projects at Lake Cle Elum Dam: The Yakima Storage Dams Fish Passage Core Team met with Reclamation’s Technical Service Center design and modeling team in Denver to see the physical models of the fish passage facilities and to discuss modeling results and the design criteria for both upstream and downstream fish passage facilities. This event facilitated agreement on design criteria and several decisions related to the ongoing physical modeling and computer modeling of the upstream and downstream fish passage facilities.
Considering the cost and operational capability of the passage during maximum drawdown of Lake Kachess: Reclamation’s Bend Field Office continues to prepare draft conceptual designs to provide passage from the lower to upper lake in the drawn-down Kachess Reservoir and from the reservoir into Box Canyon Creek. Reclamation will meet with the Yakama Nation and agencies in June to review progress on conceptual designs.
Structural and Operational Changes Keechelus-to-Kachess Conveyance (KKC) Project: The project team performed additional analysis of stream flow and water supply for this project, using the RiverWare model. A feasibility study is under way to advance the project design to feasibility level and develop updated project costs. The project team is working on the draft Environmental Impact Statement for this project.
Reviewing the environmental effects of the route of the conveyance from Keechelus-to-Kachess need to be considered along with, “with climate change will Lake Kachess be refilled after maximum drawdown.”
