data interpretation web portal

The California Environmental Data Exchange Network (CEDEN)
is a central location to find and share information about California’s water bodies, including streams, lakes, rivers, and the coastal ocean. Many groups in California monitor water quality, aquatic habitat, and wildlife health to ensure good stewardship of our ecological resources. CEDEN aggregates this data and makes it accessible to environmental managers and the public.

For more information, a one page CEDEN Fact Sheet and nine page Information Document are available for download.

 


News & Highlights

Beginning August 19, 2019, to provide more timely data, field results from SWAMP will be made available in CEDEN prior to quality assurance verification and these data will have a "Pend" compliance code until they are reviewed, at which time the compliance code will be revised. Data with the Pend compliance code are subject to revision.

The Data Entry Template Changes discussed earlier this year will be implemented on January 8. See Data Entry Template Changes - 2018 for more information.
