Embalse El Carrizal is a large reservoir situated on the upper-middle course of the Tunuyán River, approximately 60 kilometers southeast of the city of Mendoza, upstream from the city of Rivadavia in the province of Mendoza, Argentina. Built between 1965 and 1971, this earth and rock-fill embankment dam stands 46 meters tall and stretches 2,113 meters in length. The reservoir itself is an impressive body of water measuring roughly 15 by 5 kilometers, covering a surface area of 34.8 square kilometers at an elevation of 785.5 meters above sea level, with a maximum storage capacity of 462 million cubic meters. The Tunuyán River, which feeds the reservoir, originates from glacial sources in the Andes, giving the water a character shaped by snowmelt and mountain runoff. Beyond its roles in hydroelectric power generation and irrigation for the surrounding arid region, El Carrizal has earned a strong reputation as one of Mendoza's premier fishing destinations, particularly for pejerrey and carp. The reservoir is complemented by camping facilities with services along its shores, and water sports such as windsurfing and sailing are popular alongside fishing, making it a well-rounded recreational destination.
