Birds make a home at the Chico Oxidation Ponds Wilflife Sanctuary year-round. The ponds provide several different depths of water, and different birds like puddles, shallow water or six-inch pools. The largest concentration of waterfoul can be found at the Oxidation Ponds in the late fall and winter. It will be full of many species of ducks and, on occasion geese. Spring will bring some migrants to the area.
During your visit, keep your distance from the ponds. Stay on the roads and paths. In the winter, it can get very muddy, so you may consider staying on the graveled trails when it is muddy. Make sure you read the rules at the Kiosk which is at the start of the trail to the ponds.
NOTE: Unfortunately, the Oxidation Ponds are no longer open to the public. You can enjoy guided trips with the local Altacal Audubon Society or during the annual Snow Goose Festival of the Pacific Flyway in January.
