Reservoirs are artificial lakes created behind dams for water storage and power generation. Dammed reservoirs rely on natural topography and can be on-stream or off-stream. Coastal reservoirs store flood water near river mouths, preferred economically. Bank-side reservoirs form around embankments, often exceeding 6 km circumference
