Welcome to the Delta Protection Commission

The Delta Protection Commission is committed to the protection and health of the Sacramento-San Joaquin Delta in California. We protect, maintain, enhance and enrich the overall quality of the Delta environment and economy. We do this with a focus on agriculture, heritage, recreation, and natural resources while remaining mindful of the importance of the Delta to all Californians. Valuing the needs of the Delta as well as the needs of the State is fundamental to achieving the Commission’s vision: an ideal synthesis of cultural, ecological, and agricultural values in a sustainable, healthy, and celebrated way of life.
