Embalse Potrero de los Funes is a scenic mountain reservoir nestled in the Sierra de San Luis Valley, approximately 18 km (11 mi) northeast of the provincial capital of San Luis, Argentina. Sitting at an elevation of 1,210 meters (3,970 ft) above sea level, this historic body of water holds a special place in South American history as one of the continent's oldest artificial reservoirs, with the original dam dating back to 1860. Fed primarily by the Los Molles and La Bolsa streams, the reservoir drains through the Potrero River and covers a surface area of 360 hectares (890 acres) with an impressive average depth of 33 meters (108 ft). The surrounding landscape is defined by granite canyon walls, mountain ranges, gorges, waterfalls, and dense forest — creating a striking backdrop that draws visitors year-round. The reservoir sits at the heart of the town of Potrero de los Funes and is encircled by the internationally recognized Potrero de los Funes Circuit, a 6.25 km motorsport track that adds a unique character to this mountain fishing destination.
