Course
The river starts near the town of Calingasta, in the southwest of the province, from the confluence of three main rivers: the Calingasta River, the Castaño Viejo River, and the Río de los Patos. These rivers are born at an altitude of about 4,000 metres (13,000 ft) above mean sea level in the west and southwest of the province (in contrast, the Jáchal receives its Andean tributaries from the north of the province).
From Calingasta the river flows eastwards feeding the Los Caracoles, Punta Negra and Quebrada de Ullum Dams (Embalse Quebrada de Ullum) located near San Juan city, from which it continues south-eastwards receiving a few more tributaries, including the Mendoza River, to later join the Desaguadero River near the Salina Pampa de las Latas (or Salina Bermejo), at the common border of the provinces of San Juan, Mendoza and San Luis.
The river has an average flow of 56 cubic metres per second (2,000 cu ft/s). Its course is 500 kilometres (310 mi) long, and its drainage basin covers an area of 39,906 square kilometres (15,408 sq mi). The Ullum Dam is 768 metres (2,520 ft) AMSL with a reservoir covering an area of 32 square kilometres (12 sq mi) and a volume of around 440×106 cubic metres (1.6×1010 cu ft).
The upper course of the river is used for water sports such as rafting and fishing, and windsurfing and swimming at the Ullum Dam. Along its whole length, the San Juan River is heavily used for irrigation.
