Los Reyunos Dam, Embankment dam and hydroelectric station in San Rafael, Argentina.
Los Reyunos is an embankment dam and hydroelectric facility on the Diamante River in Mendoza Province. The installation uses a pumped-storage system that moves water between two reservoirs to generate electricity.
The facility began operations in 1983 and was built using stone and compacted clay. It became an important source of power generation for the Mendoza region.
The reservoir has become a gathering place where locals come to fish and enjoy water activities on weekends. This transformed how people in the region spend their free time and socialize with one another.
The best access is from nearby San Rafael, which serves as the main entry point. Visitors should know that the area can be hot and dry, especially during the summer months.
The system can pump water backward and refill the tanks at night when less power is needed. This reverse process is an unusual technique that manages energy very efficiently.
