About the Project

After a century of diking off tidal flow, the Brown Farm Dike was removed to inundate 308 ha of the Nisqually National Wildlife Refuge (Refuge) in October 2009. Along with 57 ha wetlands restored by the Nisqually Indian Tribe, the Nisqually Delta represents the largest tidal marsh restoration project in the Pacific Northwest to assist in recovery of Puget Sound salmon and wildlife populations. Over the past decade, the Refuge and close partners, including the Tribe and Ducks Unlimited, have restored more than 35 km of the historic tidal slough systems and re-connected historic floodplains to Puget Sound, increasing potential salt marsh habitat in the southern reach of Puget Sound by 50%. More »
