GeographyEdit
The 4,507-acre (18.24 km2) refuge primarily consists of intensively managed wetland impoundments, with some grassland and riparian habitats.
The Sacramento Valley is one of the most important wintering areas for waterfowl in North America.
Natural historyEdit
Colusa National Wildlife Refuge typically supports wintering populations of more than 200,000 ducks and 50,000 geese.
Wetland impoundments are intensively managed to provide optimal habitat for the dense concentration of wintering waterfowl, as well as habitat for resident wildlife and spring/summer migrants.
The grassland habitat supports several populations of endangered and sensitive species of plants. The refuge is a stronghold for populations of the endangered palmate-bracted bird's beak and the threatened giant garter snake. About 35,000 visitors come to the refuge each year for wildlife viewing and 4,000 come to hunt waterfowl and pheasant.
