Noteworthy for its agricultural productivity, ecological diversity, and complexity, the Bay Delta and Columbia River Basin is one of the largest and most complex water delivery systems in the nation. The Sacramento River and San Joaquin River meet in the Delta, which provides water to one of the most significant estuary ecosystems in the United States and provides drinking water to 25 million Californians. The Bay Delta offers habitat to 55 species of fish and 750 species of plants and wildlife. This dataset includes a printer-friendly CCA map and shapefiles for GIS.

The Agricultural Research Service of the US Department of Agriculture (USDA) in collaboration with other government agencies has a program to track changes in the sodium content of commercially processed and restaurant foods. Results of these monitoring activities are shared once a year in the [Sodium Monitoring Dataset](https://www.ars.usda.gov/ARSUserFiles/80400525/Sodium/Copy%20of%20SodiumMonitoringDatasetUpdatedJuly2616.xlsx) and [USDA National Nutrient Database for Standard Reference](https://www.ars.usda.gov/Services/docs.htm?docid=8964) and once every two years in the [Food and Nutrient Database for Dietary Studies](https://www.ars.usda.gov/Services/docs.htm?docid=12068).
