Once built, the Central Valley Project and the California State Water Project had unforeseen effects on the Sacramento–San Joaquin Delta, particularly on its historic salmon runs. The Delta is the hub of the state’s massive water distribution system, with much of the estuary’s water supply pumped to other locations. View this segment to learn how
- engineering has forever changed the Sacramento–San Joaquin Delta ecosystem.
- dams and other components of the water projects interrupt the life cycles of salmon and other fish.
- managing the effects of California’s water projects on ecosystems has cost billions of dollars.

Most of the Sacramento–San Joaquin Delta has been reclaimed for agricultural use, which has led to subsided land. View this segment to learn
- about the tidal freshwater marshes that used to exist in the Delta.
- how the construction of levees has altered the Delta.
- how reclamation of the marshes led to subsidence of the land.
- why subsided land makes levees prone to break.

In the 1950s, few people questioned the steady filling and development of San Francisco Bay. An extraordinary grassroots effort—the first of its kind in the nation—changed the fate of the Bay. View these segments to learn
- about the movement to save San Francisco Bay from development that began in the early 1960s and changed how people thought about conservation.
- that the effort to save the Bay was extraordinary in that it was both a grassroots effort and one that was led by women.

Mercury-laden sediments from mining operations in the Sierra Nevada and Coast Ranges still enter the vast network of streams and rivers that feed into San Francisco Bay. The mining activity dates as far back as California’s Gold Rush era. View this segment to learn
- how hydraulic mining techniques caused massive amounts of sediment to enter the San Francisco Bay watershed.
- where mercury (which was needed to separate gold from ore) was mined in the Bay Area.
- about the mercury that persists in area rivers and its toxic effects in the food chain.
