About Us

Facing a future of many challenges, such as population growth and climate change, it's vital the Service continues to work with its partners to plan actions that will both promote conservation of natural resources and provide water for people.

BDFWO Jurisdiction

The U.S. Fish and Wildlife Service's Pacific Southwest Region opened the Bay-Delta Fish and Wildlife Office in 2009. Creating the office co-locates the Service with other federal and state agencies to help solve the crucial issues facing Californians in the rapidly evolving Bay-Delta region, such as the delta smelt. We work with the Bureau of Reclamation, State Department of Water Resources, National Oceanic & Atmospheric Administration Fisheries, Corps of Engineers and other agencies on water projects.

Within the Bay-Delta jurisdiction, the office also has responsibility for environmental contaminants, resource damage assessment and levee work. Upstream of the Bay-Delta, the office has program responsibilities that are related to water storage projects, federal hydropower regulation, and anadromous fishes. We are also responsible for the Coastal Program.

The office is located at 650 Capitol Mall in downtown Sacramento's old main federal building and shares space with the Delta Stewardship Council (formerly CalFed) and NOAA (the National Oceanic and Atmospheric Administration Fisheries Service - two agencies heavily involved in Delta issues. The office is also just blocks away from other Delta partners, namely California's Natural Resources Agency and Departments of Fish and Wildlife and Water Resources.
