Colusa National Wildlife Refuge spreads across 5,077 acres consisting primarily of wetlands with some grasslands and riparian habitats as well. It was established in 1945 as a refuge and breeding ground for migratory birds and other wildlife, reducing damage to agricultural crops in the area. Thousands of waterfowl are present from September through March, although peak populations occur in December and January. During this two month span, more than 200,000 ducks and 75,000 geese can be seen throughout the refuge.
