Mid-Columbia Fisheries Enhancement Group (MCF) worked with project partners, landowners, and stakeholders to advance restoration plans for Bateman Island (using a combination of Salmon Recovery Funding Board and Yakima Basin Integrated Plan funds) and the lower Yakima River in the Wapato Reach (using only Yakima Basin Integrated Plan funds). Bateman Island is connected to the City of Richland by a short earthen causeway at the confluence of the Yakima and Columbia Rivers. The presence of the causeway, as outlined in our deliverable of the Bateman Island Conceptual Design Report, and the water quality assessment contracted to Benton Conservation District, has altered flow and water quality conditions in the Delta and created a water temperature barrier that can delay adult salmon migration. Flow modeling indicated that salmonid migratory conditions in the Delta would improve with causeway breaching. Through assessment and public scoping, MCF identified alternatives to breach the causeway to allow flow along the south side of the island while accommodating recreational and emergency access to the island. The project also identified and addressed the concerns of stakeholders in the area, including the landowners (Washington State Department of Natural Resources, US Army Corps of Engineers), lessees (City of Richland, Columbia Park Marina), and recreationists. Alternative development considered mobilization of sediment deposited to the west of the causeway, bank scour, reduction of rearing habitat for non-native species, protection of marina resources, and relative project costs. Monitoring of water quality parameters and fish utilization continued throughout the alternative development process. Although a preferred alternative has not been finalized, and the new partnership with the USACE is still in development, MCF will continue to support fisheries co-managers and regulatory agencies as they work with stakeholders and partners to select a preferred alternative. In particular, MCF will provide technical support and outreach documents and materials related to past work and will continue to pursue funding to support ongoing temperature monitoring. The goals of the Bateman Island project remain the development of design alternatives to facilitate selection of a preferred alternative to improve migratory conditions for juvenile and adult steelhead, spring, summer, and fall Chinook, Coho, and Sockeye salmon at the confluence of the Yakima and Columbia Rivers. In addition to the work on Bateman Island, MCF supported fisheries co-managers in completing the Lower Yakima River Action Plan and its subset plan, titled the "Wapato Reach Action Plan". Project work focused on the Wapato Reach, located between Union Gap and the Sunnyside-Mabton Bridge (RM 106-RM 60), but the full extent of the Lower Yakima River Action Plan will be from Union Gap downstream to Bateman Island. Salmon Recovery Funding Board funds were completely closed out by June 30, 2016. Only Yakima Basin Integrated Plan funds were used for ongoing project activities after June 30, 2016.
