Modify or construct a new intake structure to meet DSOD regulatory standards. A storage restriction of about 55 feet below the dam crest has been put in place to protect the public, reducing the allowed storage capacity to 52,553 acre-feet. Almaden Reservoir is one of Santa Clara County's six original reservoirs, built in 1935, and is one of 10 current reservoirs operated by the Santa Clara Valley Water District. The reservoirs do also provide incidental flood protection by containing runoff early in the rainfall season, serve recreational needs, and benefit the environment by storing water to maintain flow in the creeks. Although pure water is rarely found in nature (because of the strong tendency of water to dissolve other substances), the characterization of water quality (i.e., clean or polluted) is a function of the intended use of the water. Water helps to restore fluids lost through metabolism, breathing, sweating, and the removal of waste. A number of natural states of water exist.

(For a discussion of the handling of sewage and other forms of waste produced by human activities, see waste disposal and solid-waste management.). [93] An example of the oxidation of water is: Water can be split into its constituent elements, hydrogen, and oxygen, by passing an electric current through it. Although groundwater may appear crystal clear (due to the natural filtration that occurs as it flows slowly through layers of soil), it may still be polluted by dissolved chemicals and by bacteria and viruses. Dead zones occur worldwide; one of the largest of these (sometimes as large as 22,730 square km [8,776 square miles]) forms annually in the Gulf of Mexico, beginning at the Mississippi River delta. The reservoirs have a total storage capacity of approximately 170,000 acre-feet (One acre-foot is enough water for two families of five for one year.). The accepted IUPAC name of water is oxidane or simply water,[99] or its equivalent in different languages, although there are other systematic names which can be used to describe the molecule.
