Dique Cuesta del Viento is a striking reservoir nestled in the northern region of San Juan province, Argentina, approximately 160 kilometers north of the provincial capital via Ruta Nacional 40. Covering 1,600 hectares and sitting at an elevation of 529 meters above sea level, this reservoir is set against a dramatic backdrop of dark volcanic rock and arid mountain terrain. The vivid green water contrasting with the surrounding rocky landscape makes it one of the most visually distinctive fishing destinations in the Cuyo region. The climate is warm, dry, and semi-arid, with a wide daily temperature range typical of Andean foothill environments. The reservoir is accessible from the nearby town of Rodeo and is well known not only as a fishing destination but as a world-class wind sports venue — a characteristic that has a direct and significant impact on fishing conditions throughout the day.
