Refuge map

Estuary waters provide vital food resources for juvenile salmon as they pause to become acclimated to salt water before entering the Pacific Ocean. Bald eagles are present year-round; there are 30 to 35 active nest sites.

Other fish species using the estuary include American shad, smelt, perch, starry flounder, bass, catfish, and Pacific lamprey. Harbor seals use sandbars and mud flats as resting sites at low tides, while seals and California sea lions feed on fish in the estuary. Beaver, raccoon, weasel, mink, muskrat, river otter, Columbian white-tailed deer and invasive nutria also live on the islands.
