About
ABOUT US
Established in 1937, Sacramento National Wildlife Refuge was created to provide habitat for migratory birds, manage sensitive species, and alleviate crop depredation. It serves as the headquarters for the Sacramento National Wildlife Refuge Complex, supporting over 250 species of birds and massive winter concentrations of waterfowl. Historically part of the Colusa Plains, the refuge's extensive wetlands were originally constructed by the Civilian Conservation Corps between 1937 and 1942.
