San Francisco Bay-Delta

The San Francisco Bay-Delta is a vital estuary in Northern California where the Sacramento and San Joaquin rivers converge and flow into the Pacific Ocean. It functions as a natural habitat for many species and as a crucial water source for agriculture, industry, and cities. The delta also acts as a giant filter, improving water quality. However, it faces environmental challenges from urban development, water diversions, erosion, and climate change, which threaten its ecosystems and the supply of clean water for millions. Efforts are ongoing to balance ecological health with human use and ensure its sustainability.
