Estuary Partnership

What Estuary Partnership does

The Estuary Partnership (legally Lower Columbia Estuary Partnership) is a 501c3 nonprofit founded in 1995 and headquartered in Portland, Oregon. Designated as one of 28 National Estuary Programs, it focuses on the lower 146 miles of the Columbia River from Bonneville Dam to the Pacific Ocean, spanning 28 cities and portions of nine counties in Oregon and Washington. Its mission is to restore and care for the waters and ecosystems of the lower Columbia River.

Its core services fall into six lines: large-scale habitat restoration (including the East Fork Lewis River Reconnection Project, the completed Steigerwald Reconnection Project, and Campen Creek); K-12 environmental education delivered to 2,945 students across 12 school districts via classroom lessons, field trips, and a Big Canoe program; non-motorized water trail infrastructure (Lower Columbia River Water Trail, Lewis River–Vancouver Lake Water Trail); ecosystem monitoring and research underpinned by the Columbia River Estuary Ecosystem Classification (CREEC), Landscape Assessment Tools, and the Lower Columbia Regional Habitat Restoration Inventory (tracking 284 projects and 35,000+ acres since 1999); green stormwater projects at schools; and volunteer programs that mobilized 1,000+ volunteers to plant approximately 20,000 native trees and shrubs in the 2025-26 season.

The organization is funded primarily through federal, state, and local government grants — including EPA National Estuary Program funds, NOAA Restoration Center, Bonneville Power Administration, Washington Department of Ecology, Oregon Watershed Enhancement Board, and Bipartisan Infrastructure Law and Inflation Reduction Act appropriations — supplemented by individual donations, corporate sponsorships (tiered as Tributary, Floodplain, and Wetland sponsors), an annual Celebrate the Columbia fundraiser, and passive fundraising (Fred Meyer Community Rewards, BottleDrop). Services to schools and communities are delivered at no cost to participants. The organization is governed by a Board of Directors and led by Executive Director Elaine Placido, with technical leadership including Principal Restoration Ecologists Jenny Dezso and Marci Krass and a Monitoring Team reinforced by Research Scientist III Jacob Rudolph (mid-2026 hire).
