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.
