San Francisco Bay
San Francisco Bay is a shallow, productive estuary that drains water from approximately forty percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains passes through the Bay to the Pacific Ocean. Specifically, both rivers flow into Suisun Bay, which flows through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. However, the entire group of interconnected bays is often called the San Francisco Bay.The above text is a snippet from Wikipedia: San Francisco Bay
