Our research vessel, the Sentinel, is the principal platform for conducting scientific studies and collecting water quality phytoplankton, zooplankton, and benthos data in the Sacramento-San Joaquin Delta, Suisun Bay, and San Pablo Bay. ©DWR/2016

The Division of Environmental Services (DES) ensures we comply with extensive federal, state, and local regulations. With science as our foundation, the information we gather is used to support water and resource management throughout California; assist in balancing both human and environmental needs; and inform management decisions, the science community, and general public. Funding comes from a mixture of federal cost shares and special and State Water Project funds.

Our work includes:

  • Developing the best available science
  • Investigating multiple subject areas
    • Fish
    • Food web species ­
    • Waterfowl
    • Water quality
    • Habitat
    • Connections between topics
  • Performing research, ongoing monitoring, and assessments primarily in the Feather River, Yolo Bypass, Suisun Marsh, and Sacramento-San Joaquin River Delta
    • Water quality
    • Biological species (fish, birds, invertebrates, and harmful algal blooms, plants, and cultural resources)
  • Restoring habitats and mitigating State Water Project impacts to the natural environment through restoration programs
    • Delta Pumping Plant Fish Protection Agreement (known as the Delta Fish Agreement)
    • Fish Restoration Program Agreement
    • Yolo Bypass Habitat Restoration Program
