Thousand Acres is part of the 1,500 acre natural area at the confluence of the Sandy and Columbia rivers known as the Sandy River Delta in the Columbia River Gorge. The site, owned by the US Forest Service, was historically a dynamic alluvial floodplain with two distributaries of the Sandy River flowing across it and a mosaic of bottomland forests, wetlands and meadows. The site was severely impacted by deforestation, highway and railroad development, hydrology modifications, and cattle grazing. As a result, the floodplain wetland site became disconnected, had poor water quality, and was

Louisiana Swamp is a wetland site directly along the Columbia River, 4.5 miles west of Clatskanie. The landowner, a private forest products company GreenWood Resources, Inc. worked with the Estuary Partnership, Lower Columbia River Watershed Council, Columbia Soil and Water Conservation District and the US Fish and Wildlife Service to restore 35 acres of habitat at the site, and the project broke ground in August 2013. Before the restoration began, the site was a marshy field of invasive reed canarygrass, and was too wet to farm trees like the rest of the property was used for. Westport Slough

The East Fork Lewis River (EFLR) is an important stream in the lower Columbia River system. It is one of the few undammed rivers with no hatchery programs, and supports five runs of native fish including fall chinook, winter & summer steelhead, coho and chum. It has been a designated wild steelhead genetic sanctuary since 2014. In 2017, the Estuary Partnership worked with local partners to restore two side channels along the river for salmon and steelhead. While the EFLR supports several salmonid stocks, the river and riparian areas have been impacted by dredging, mining, deforestation

Today, Hamilton Creek, located in the Columbia River Gorge in Skamania County, Washington, supports runs of coho salmon and steelhead. Historically, Hamilton Creek was home to abundant winter steelhead, chum, coho, and fall Chinook runs who utilized its diversity of aquatic habitats for their various life stage needs. Large sections of the creek were impacted by road development, timber harvest and forest fires, leaving it without the large wood jams and streamside vegetation that are necessary for healthy salmonid habitats. In 2017, the Estuary Partnership worked with the US Forest Service
