Mallard II moving mud, with its bucket outstretched. Mallard II is a wooden-hulled clamshell dredger [2] used to maintain levees on the San Francisco Bay Salt Ponds. [3] [4] Mallard II was constructed in 1936, [5]: 45 and is "probably the oldest operating dredge in California"; [6]: 51 she is owned and operated by Cargill Salt.
The South Bay Salt Works, a Californian saltern, with salt ponds.. A saltern is an area or installation for making salt.Salterns include modern salt-making works (saltworks), as well as hypersaline waters that usually contain high concentrations of halophilic microorganisms, primarily haloarchaea but also other halophiles including algae and bacteria.

As of 2004, the refuge spanned 30,000 acres (120 km 2) of open bay, salt pond, salt marsh, mudflat, upland and vernal pool habitats located throughout south San Francisco Bay. About 9,000 acres (36 km 2) of salt ponds within the refuge are managed by Cargill Salt, which has perpetual salt-making rights. Cargill uses the salt ponds to ...
The salt ponds of the salt works fall within San Diego Bay National Wildlife Refuge. [9] [30] The salinity of the salt ponds creates an environment which breeds brine flies (Ephydridae) and brine shrimp , a food source for the birds. [18] During the winter months, there are monthly tours out into the salt ponds to observe migratory birds. [31]
Bittern is commonly formed in salt ponds where the evaporation of water prompts the precipitation of halite. These salt ponds can be part of a salt-producing industrial facility, or they can be used as a waste storage location for brines produced in desalination processes. [3] Bittern is a source of many useful salts.
Evaporation ponds are artificial ponds with very large surface areas that are designed to efficiently evaporate water by sunlight and expose water to the ambient temperatures. [1] Evaporation ponds are inexpensive to design making it ideal for multiple purposes such as wastewater treatment processes, storage, and extraction of minerals .
The southern end of the lake was once known as the Onondaga Salt Reservation. [2] The building that houses the museum was built in the 1930s and is believed to be built from wood used in former salt factories. [3] The Erie Canal hastened and expanded the development of the salt industry and the city of Syracuse. [4]
