Los Reyunos Dam

The Los Reyunos Dam is a dam on the Diamante River, in central Mendoza Province, Argentina, some twenty-two miles (thirty-five kilometers) from the city of San Rafael. The dam, built of stone and compacted clay to minimize execution and cost, is 440 feet (134 meters) high and contains a reservoir covering an area of 1,828 acres (7.34 km²).

The dam is used to generate hydroelectricity. This is done in a power station located below the level of the reservoir. About one mile (two kilometer) downstream is a smaller, compensation dam 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 (such as windsurf, canoeing) and in the surrounding mountains (such as hiking).
