San Roque Lake

The San Roque Lake is a reservoir in the province of Córdoba, Argentina. It was created by the damming of several rivers, especially the Suquía and the Cosquín. It is located next to the city of Villa Carlos Paz, about 600 m above mean sea level. It has a surface area of 16 km², an average depth of 16 m, and a maximum volume of 180 million m³.

The dam was initially built to provide fresh water for the capital and its surroundings. It was designed in 1884 by the engineering firm of Cassaffousth, Bialet Massé and Dumesnil, finished in 1886, and inaugurated officially in 1890. Two years later the dam was suffering from a complete lack of maintenance, however, and a political scandal erupted.
