Lower Columbia Estuary Partnership (archived)

The Lower Columbia Estuary Partnership is a non-profit, a National Estuary Program, and a collection of dedicated scientists, educators, and community members who are passionate about the Columbia River. We focus on the lower 146 miles of the Columbia River, from Bonneville Dam to the Pacific Ocean, including the tidally influenced portions of tributaries in that area. The watershed includes 28 cities, nine counties, and 45 school districts within the states of Oregon and Washington.
