During many periods of the year and in many places around the world, the demand for freshwater for human use exceeds what is sustainably available, while growing populations, increasing wealth, and climate change all aggravate the already dire current status. Historically, we turned to constructing dams in order to regulate freshwater availability. Building and operating dams and reservoirs brought humanity much good, to this present day.
