Lahontan Region Water Quality Monitoring Dashboard
(Works best in the latest versions of FireFox, Chrome, or Safari.)
The California Environmental Data Exchange Network (CEDEN)
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.
Note: The Water Quality Dashboard does not include all regional SWAMP data. Data not displayed in the dashboard is available in CEDEN.
