Sutter National Wildlife Refuge

The Sutter National Wildlife Refuge is a protected area in Sutter County containing wetlands, riparian corridors, and grasslands spread across the Sacramento Valley. The site spans over 2,500 acres and links different habitats that support vast numbers of migratory birds.

The refuge was established in 1945 by the U.S. Fish and Wildlife Service as part of a broader conservation network in the Sacramento Valley. It grew from the need to protect bird populations and preserve wetlands for future generations.

The refuge serves as a learning space where visitors can observe how wetlands support wildlife and understand conservation efforts firsthand. People come here to connect with nature and see endangered species in their natural environment.

The site is open year-round for bird watching, photography, and hiking, with additional hunting activities during specific seasons. Visitors should bring weather-appropriate clothing and binoculars, and keep to marked paths to avoid disturbing wildlife.

The area floods annually through the Sutter Bypass, temporarily creating massive feeding grounds for migrating ducks and geese passing through the region. These inundations are unpredictable and turn parts of the refuge into shallow lakes for weeks at a time.
