To protect and enhance the health of the Sacramento and American rivers, Regional San and the Sacramento Stormwater Quality Partnership joined forces in 1991 to create a Coordinated Monitoring Program (CMP). The fundamental purpose of the CMP is to develop high-quality data to aid in the development and implementation of water quality policy and regulations in the Sacramento area. With the help of Regional San’s Environmental Laboratory, river-water data is collected and tested for a variety of constituents.The CMP identifies water quality conditions, trends and influences that are invaluable in defining the health of the river system in a cost-effective manner.

CMP-partnering agencies support many area programs committed to safeguarding river water quality in the Sacramento and American rivers. Data from the program is available on CEDEN.
