About the Sacramento NWR Complex

Sacramento NWRC HeadquartersSacramento National Wildlife Refuge Complex is comprised of 5 National Wildlife Refuges (Sacramento, Delevan, Colusa, Sutter and Sacramento River NWRs) and 3 Wildlife Management Areas (Willow Creek-Lurline, Butte Sink and North Central Valley WMAs).  Sacramento NWR, located near Willows, CA, serves as the headquarters for the Complex.

A National Wildlife Refuge Complex is an administrative grouping of two or more refuges, wildlife management areas or other refuge conservation areas that are primarily managed from a central office location. Refuges are grouped into a complex structure because they occur in a similar ecological region, such as a watershed or specific habitat type, and have a related purpose and management needs. Typically, a project leader or complex manager oversees the general management of all refuges within the complex and refuge managers are responsible for operations at specific refuges. Supporting staff, composed of administrative, law enforcement, refuge manager, biological, fire, visitor services and maintenance professionals are centrally located and support all refuges within the complex.

The Sacramento National Wildlife Refuge Complex includes these 5 National Wildlife Refuges (NWR) and 3 Wildlife Management Areas (WMA) (click here to view the Complex Location Map) : 

The Complex's National Wildlife Refuges were established between 1937 and 1989.  Four of these refuges (Sacramento, Delevan, Colusa and Sutter) were established primarily to provide wintering habitat for waterfowl and in some cases to reduce crop damage by waterfowl.  The Sacramento River NWR was established to help protect and restore riparian habitat along the Sacramento River between Red Bluff and Colusa.  All NWR lands are owned and managed by the U.S. Fish & Wildlife Service.

The Complex's Wildlife Management Areas were established between 1979 and 1991 in order to preserve wetland habitat for wintering waterfowl and other wetland-dependent wildlife.  The WMAs consist of a combination of private lands protected with conservation easements and Service-owned lands (the Butte Sink Unit of the Butte Sink WMA, and the Llano Seco Unit of the North Central Valley WMA). The conservation easements are owned and managed by private landowners, and the Service-owned lands are owned and managed by the U.S. Fish & Wildlife Service.

The Complex headquarters is located at the Sacramento NWR, 752 County Road 99W, Willows, California 95988.
