Saving the Bay is the first television program to tell the full story of San Francisco Bay, the most important estuary of the Pacific Coast of the Americas and the second largest estuary on the North American continent after Chesapeake Bay. Narrated by Robert Redford and shot in HDTV, Saving the Bay is comprised of four one-hour episodes tracing the Bay's history from before the last Ice Age through today and covers the entire northern California watershed from the Sierra Nevada mountains to the Farallon Islands in the Pacific Ocean. The series also highlights the story of three women who rallied an entire region to save San Francisco Bay from becoming little more than a river.
