The Quebrada de Ullúm Dam, or simply Ullúm Dam, is an embankment dam on the San Juan River, just west of San Juan in Ullúm Department of the Province of San Juan, Argentina. It is located at the gorge of the Quebrada de Ullum, 18 kilometres (11 mi) upstream from the provincial capital San Juan, and creates a reservoir with an area of 32 square kilometres (12 sq mi), a volume of 440 million cubic metres (16×109 cu ft), and average and maximum depths of 15 and 40 metres (49 and 131 ft), respectively. The reservoir feeds a hydroelectric power station with an installed power capacity of 45 megawatts (60,000 hp).[1]
