Discover the wetlands and wildlife of the 16,800-acre Yolo Bypass Wildlife Area between Davis and Sacramento in the Central Valley of California.

Yolo Basin Foundation provides a myriad of programs to make this possible. Our partnership with California Department of Fish & Wildlife, other government agencies, the agriculture and wetlands community, and conservation groups is internationally recognized.

Discover the Flyway is our largest program, with over 4,000 K-12 students participating annually. We have events for all ages, including California Duck Days Wetlands Festival, Flyway Nights Speaker Series, Wildlife Area Tours, Gaggle of Gatherings Field Trips and Workshops, Bat Talk & Walks, and many others.

Thank you for your interest, and we welcome your participation and support!


Spring has arrived at the Wildlife Area. Water is being drawn down in many ponds and maintenance has begun. The rice fields are drying out and will be planted soon. There is no hunting now, so people may walk in the "closed zone" - indicated by a red dashed line on the map of the Wildlife Area.

This summer water will be kept in several ponds surrounding Parking Lot B. This includes the area just north of B, the pond where the ramp is to the west of B, as well as the pond on the trail directly east (where the Black-crowned Night Heron roost is). Also, there will be water southwest of B on the auto loop through May.

In addition, there will be summer water in the ponds to the north of Parking Lot F, and from there you can look east across the Toe Drain to see the heron rookery.

Every summer 200 acres of rice fields are fallowed and shallowly flooded for shorebird habitat. The fields will be located to the east of Parking Lot C in the same location as last year. Flooding of the first field will begin July 1 with second beginning on August 1. Park in C and walk east on the trail directly opposite the parking lot entrance to get there.

Please note: The water you see north of the Yolo Causeway is run-off from the South Davis Drain and not Wildlife Area water.
