Nisqually Reach Aquatic Reserve
About the Reserve
The Nisqually Reach Aquatic Reserve, located in south Puget Sound, extends from the Nisqually River Delta across Nisqually Reach and around Anderson Island and Ketron Island to the shores of McNeil Island.
Designated in 2011, the Nisqually Reach Aquatic Reserve is part of a network of protected ecosystems in the Nisqually Reach area, including the Billy Frank Jr. Nisqually National Wildlife Refuge. The Nisqually Indian Tribe and the Nisqually Land Trust also manage adjacent lands for conservation and protection. Together, these connected lands add up to more than 17,920 acres that have been set aside to preserve and restore this area’s distinctive habitat qualities and the species they support.

A Look at Nisqually Reach Aquatic Reserve
Species and Habitats
The Nisqually Reach Aquatic Reserve encompasses a variety of habitat areas. High bluffs with sand and gravel beaches are prevalent features in the reserve. Small ‘pocket’ estuaries provide refuge and rearing areas for numerous juvenile fish and invertebrates. In the deep waters between the delta and Anderson Island lie great shifting sand dunes— formed by the dynamic confluence of sediment carried from the Nisqually River and the extreme tidal exchanges in the South Sound.
Shallow subtidal and lower intertidal areas support eelgrass and a large variety of seaweed. These habitats provide a home for a wide diversity of resident and migratory birds, fish, mammals, and invertebrate species including pigeon guillemots and red-throated loons, Chinook salmon and pile perch, harbor seals, and river otters, and Dungeness crabs and glassy sea squirts.
The Nisqually River, Delta, and Reach all play an important role in the life cycle of salmon and other fish species. When juvenile salmon migrate out of the river delta, they use the shorelines of the aquatic reserve as shelter and foraging grounds, as well as to adapt to saltwater before leaving the South Puget Sound. When they return, adult salmon spend time in the reserve before migrating upstream to spawn.
Citizen Science and Stewardship
A Citizen Stewardship Committee, led by the Nisqually Reach Nature Center, organizes pigeon guillemot surveys and forage fish monitoring in and around Nisqually Reach Aquatic Reserve. The committee also works to educate others about nearshore ecology, the Aquatic Reserve's condition, and planning issues that affect the reserve.

Nisqually River Delta Restoration
The Nisqually River Delta became the site of the largest estuary restoration project in Puget Sound when tidal inundation was returned to 750 acres of the delta by dike removal in 2009. The US Geologic Survey and the Nisqually Indian Tribe are conducting multidisciplinary monitoring of the ecosystem's response to these changes.
