Embalse Los Quiroga sits on the Río Dulce in the province of Santiago del Estero, Argentina, positioned conveniently close to both the provincial capital of Santiago del Estero and the neighboring city of La Banda. The reservoir was created by the Los Quiroga Dam, a structure completed in 1956 that combines a reinforced concrete wall stretching 390 metres in length and standing 7 metres tall, extended further by an earth wall running an additional 1,200 metres. With 32 floodgates controlling water levels and flow, the dam functions as both a level-keeping and diversion structure, giving it a dynamic character that anglers should keep in mind when planning visits. The reservoir has long been recognized as a premier fishing destination in the region and draws consistent tourism thanks to its natural surroundings. The nearby Los Quiroga Hydroelectric Power Plant, inaugurated in 1963, operates in conjunction with the dam and is part of the broader infrastructure that shapes water conditions throughout the year.
