The Maury Island Aquatic Reserve is located in central Puget Sound and southwestern King County, including the eastern shores of Maury Island. The reserve is approximately 5,530 acres of state-owned aquatic bedlands and tidelands located in Quartermaster Harbor. The reserve boundaries include all of the known Quartermaster Harbor herring stock spawning grounds-representing one of only 18 distinct Pacific herring spawning areas in Puget Sound. The area is unique within central Puget Sound because of the diverse set of habitats and species which include extensive eelgrass beds, kelp beds, sand and mudflats, herring, surf smelt, and sand lance spawning grounds.
