Yolo Bypass Wildlife Area - Seasonal Wetlands

Seasonal Wetlands

Most wetland on the Wildlife Area are managed as seasonal wetlands. They go through an extensive dry period during the spring and summer months. Typically these ponds are drained April 1 to stimulate the germination of Swamp Timothy. They may receive a brief summer irrigation and then are flooded in September to provide wetland habitat for migratory waterfowl and shorebirds.
