The Confederated Tribes and Bands of the Yakama Nation will use this grant to restore the floodplain on South Fork Cowiche Creek, a tributary to the Naches River in the Oak Creek Wildlife Area in Yakima County. The partners will install tree root wads and large logs along 2 miles of the creek on land owned by the Washington Department of Fish and Wildlife. These woody materials create places for fish to rest, feed, and hide from predators. They also slow the river, which reduces erosion and allows small rocks to settle to the riverbed, creating areas for salmon to spawn. Finally, they change the flow of the river, creating riffles and pools, which give salmon more varied habitat. The composition of the streambed and length of time that water spends flowing through the substrate reduce stream temperature and increase nutrient cycling that is beneficial to aquatic organisms. The work will reconnect South Fork Cowiche Creek with its floodplain. During seasonal high flows, the woody material will cause flood waters to leave the channel and disperse over large areas. The overland flow will recharge the groundwater, increasing flows to the stream during summer, and reducing flood risk downstream. The South Fork Cowiche Creek is used by middle Columbia River steelhead, which are listed as threatened with extinction under the federal Endangered Species Act.
