A dam or reservoir is a storage space for water, hydrocarbons or gases. Reservoirs generally refer to enlarged natural or artificial lakes, cisterns, or cisterns that store water using dams or locks. Reservoirs can be created by controlling streams that discharge existing bodies of water. They can also be built in river valleys using dams. Alternatively, reservoirs can be constructed by excavating level ground and/or constructing retaining walls and embankments.
