San Francisco Bay is a shallow bay in northern California, along the Pacific Ocean. It is an estuary because salt water from the ocean mixes with fresh water from rivers, especially the Sacramento and San Joaquin rivers. These rivers carry water from the Sierra Nevada mountains through the Central Valley. Water from about forty percent of California enters the bay.
The Sacramento and San Joaquin rivers enter the Suisun Bay. There water flows through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay. This connects at its south end to the San Francisco Bay. The San Francisco Bay is connected to the Pacific by a strait called the Golden Gate. However, this entire group of interconnected bays is often called "the San Francisco Bay".
San Francisco Bay lies in the US state of California and is surrounded by a region known as the San Francisco Bay Area, that includes the big cities of San Francisco, Oakland, and San Jose.
The Bay covers somewhere between 400 [1] and 1,600 [2] square miles (1,040 to 4,160 square kilometres), depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement.
