Washington

Washington's Puget Sound is a complex ecosystem directly adjacent to a robust metropolitan area that scientists from the USGS Western Fisheries Research Center study. Recent surveys have looked at juvenile surf smelt, a key link in the food web that are consumed by predators such as salmon, orca, and many marine birds.

    Elwha River Restoration Project

    From 2011 to 2014, the Nation’s largest dam removal project to date took place in Washington State, allowing the Elwha River to once again flow unimpeded from its origin in the Olympic Mountains to the Strait of Juan de Fuca. Nearly 100 years of sediment (30 million tons) had accumulated behind two dams, and about two-thirds of that (20 million tons) was released, dramatically affecting the...

    Estuarine Ecosystem Recovery in Puget Sound

    A clean and abundant sediment supply is critical for building and maintaining viable estuarine and wetland habitats. However, in many coastal regions, dikes, levees, and dams have disconnected water and sediment supply to estuarine and wetland habitats, altering sedimentation patterns, water quality, and nutrient loads. Dike and dam removal have become important methods for restoring river and...
