May 7, 2025 โ This spring, NOAA partner the Lower Columbia Estuary Partnership broke ground on a large-scale salmon habitat restoration project on the lower East Fork Lewis River in Washington State. This project will support the recovery of threatened steelhead and salmon on one of the few undammed rivers in the Lower Columbia River watershed. It will also inject millions into the local economy and generate hundreds local jobs in construction, heavy equipment operations, trucking, engineering, forestry, and other industries.
In addition, the work will help maintain fishing opportunities that further contribute to the local economy.
Flooding Destroys Habitat
In 1996, Steve Manlow, Executive Director of the Lower Columbia Fish Recovery Board, watched in horror as a 500-year flood event destroyed crucial salmon and steelhead habitat on the lower East Fork Lewis River. Flood waters breached the levees around nine abandoned gravel mining pits, fundamentally shifting the riverโs course.
This once-braided, multi-channel river began flowing through the excavated pits. It formed a series of interconnected warm-water ponds that prevent salmon and steelhead from migrating upstream for much of the year. The river channel deepened, cutting off floodplain habitat and causing severe erosion downstream.
