Billy Frank Jr. Nisqually National Wildlife Refuge

The Nisqually River Delta, a biologically rich and diverse area at the southern end of Puget Sound, supports a variety of habitats. Here, the freshwater of the Nisqually River combines with the saltwater of Puget Sound to form an estuary rich in nutrients and detritus. These nutrients support a web of sea life - the benefits of which extend throughout Puget Sound and beyond.

While most major estuaries in the state have been filled, dredged, or developed, Nisqually River's has been set aside for wildlife. In 1974, Nisqually National Wildlife Refuge was established to protect the delta and its diversity of fish and wildlife habitats. The Nisqually estuary was restored in 2009 by removing dikes and reconnecting 762 acres with the tides of Puget Sound. This is the largest estuary restoration project in the Pacific Northwest and an important step in the recovery of Puget Sound.
