Embalse San Roque is a storied reservoir nestled in the Punilla Valley of Córdoba Province, Argentina, sitting at approximately 600 meters above sea level near the city of Villa Carlos Paz. Fed primarily by the Cosquín and San Antonio Rivers, along with Las Mojarras and Los Chorrillos streams, the reservoir drains through the Suquía River and covers a surface area of roughly 16 km². With an average depth of 16 meters, a maximum depth of approximately 29.5 meters, a perimeter of about 30.72 km, and a total water volume of up to 201 million cubic meters, this is a substantial body of water offering diverse fishing opportunities. The dam itself stands 51.3 meters tall with a crest length of 145 meters, and the reservoir's maximum spillway discharge capacity reaches 280 m³/s. Originally constructed in the late 1880s and rebuilt in 1944, Embalse San Roque serves as the primary drinking water source for roughly 1.5 million residents of the Córdoba region while simultaneously functioning as a major recreational hub — more than 50% of Córdoba Province's tourist facilities are concentrated in the surrounding Punilla Valley.
