A Reservoir is a large tank used for storing water and collecting it for use when needed. Reservoirs in Azerbaijan are mainly built for water resource management and to supply water for agriculture. These reservoirs, which belong to the category of hydrological monuments, play an important role in the development of water management in surrounding areas. They are sometimes used for irrigation, drinking water supply, and electricity generation. In Azerbaijan, there are well-known Reservoirs such as Mingachevir, Shamkir, and others. These facilities have a positive impact on the region’s economic and environmental situation.
