- What is it?
- CEDEN is the State Water Board's data system for surface water bodies in California
- Who is it?
-
CEDEN was created by the State Water Resources Control Board with support from the Surface Water Ambient Monitoring Program (SWAMP).
To include all available statewide data (such as that produced by research and volunteer organizations), CEDEN works with four regional data centers:
• San Francisco Bay-Delta and surrounding watersheds: San Francisco Estuary Institute (SFEI)
• Central Coast: Moss Landing Marine Laboratory (MLML)
• Central Valley: Michael L. Johnson, LLC (MLJ-LLC)
• Southern California: Southern California Coastal Water Research Project (SCCWRP)
Anyone can access CEDEN data online or submit new data through these regional centers
- Why is it needed?
- The state’s valuable waterways provide many services, including water supply, wildlife habitat, recreation, and flood control. These functions can be hampered by pollution or other manmade stressors. To keep an eye out for problems and improvements, federal environmental regulations require each state to periodically assess the condition of surface water bodies. CEDEN consolidates California’s data in a central location, where it can be easily accessed and used for statewide management efforts. CEDEN data is also useful to organizations interested in water quality, scientists, citizen groups, and the public for reports and research purposes.
