Description Salt evaporation ponds formed by salt water impounded within levees in former tidelands on the western shore of San Francisco Bay, in Redwood City. There are many of these ponds surrounding the South Bay. As the water evaporates, micro-organisms of several kinds come to predominate and change the color of the water. First come green and red algae, then orange brine shrimp. Other organisms can also change the hue of each pond. Finally, when the water is evaporated, the white of salt alone remains. This is harvested with machines, and the process repeats.
