Los Reyunos Dam
The Los Reyunos Dam is an embankment dam on the Diamante River, in central Mendoza Province, Argentina, some twenty-two miles from the city of San Rafael. The dam, built of stone and compacted clay to minimize execution and cost, is 440 feet high and contains a reservoir covering an area of 1,828 acres.
The dam is used to generate hydroelectricity. This is done with a pumped-storage power station located below the level of the reservoir. About one mile downstream is a smaller, compensation dam, which forms the lower reservoir, called El Tigre. During the hours of decreased power demand, water is pumped from the reservoir of El Tigre back into Los Reyunos to stabilize the water level.
The reservoir is employed in raising Salmonidae and silverside, allowing for sport fishing. Los Reyunos Fishing and Nautical Club, along with private summer residences and a hotel, lies on the western shore of the reservoir and serves as a base for activities in the lake and in the surrounding mountains.
