Sacramento-San Joaquin Delta

The Sacramento-San Joaquin Delta is a network of interconnected rivers, marshes, and islands in Northern California, serving as a critical water system for agriculture, industry, and cities. It functions as a natural hub that channels freshwater from the Sierra Nevada mountains into the San Francisco Bay and provides water for millions of residents and farms. Its fragile ecosystem supports diverse wildlife but faces challenges from levee failures, pollution, and climate change, requiring ongoing management to balance environmental health with water needs for California.
