The Sacramento–San Joaquin River Delta watershed covers more than 75,000 square miles and includes the largest estuary on the west coasts of North and South America. This is the only inland delta in the world. Two major rivers merge in the Delta, California’s Central Valley, irrigating some of America’s richest farmland before flowing into the San Francisco Bay. Two hundred years ago, California’s Delta region was a swamp. If you are looking for some new images, the Delta is a photographer’s ideal destination.
