East Fork Lewis River Side Channel

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.

Sandy River Delta Thousand Acres

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 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

La Center Wetlands Floodplain Restoration Project

La Center Bottoms is a series of wetlands along the East Fork Lewis River just upstream from the city of La Center. Clark County acquired a great deal of high-quality floodplain wetland habitat along the East Fork Lewis River through its Legacy Lands program, including the Bottoms, with the purpose of conserving natural resources as well as providing recreational access to the public. The East Fork Lewis is a high priority river for salmon and steelhead, and the County and the Estuary Partnership share the goal of protecting habitat in this area, so we partnered on a project that ultimately
