About Us

Sutter NWR was established in 1945 with funds from the Migratory Bird Hunting and Conservation Stamp Act (today it is known as Federal Duck Stamp) and the Lea Act. It was established to provide feeding and nesting areas for migratory birds and alleviate crop depredation.

About 80% of the refuge is located in the Sutter Bypass. During major flood events, the Bypass diverts winter flood water from the Sacramento River, which may cover portions of the refuge with up to 12 feet of water.

Waterfowl are present September through April and numbers peak later than most other refuges in the Complex

between January and February. Sutter NWR regularly supports wintering peak populations of over 150,000 ducks and 70,000 geese.

The refuge provides habitat for several Federal and State endangered and threatened species, including giant garter snake, Chinook salmon, yellow-billed cuckoo, and Swainson's hawk.

There are limited wildlife viewing and photographic opportunities from Hughes Road, which bisects the refuge.
