The dam is made of compacted loose materials. It has a volume of 4 million cubic metres (140×10^6 cu ft), measuring 37 metres (121 ft) in height and 3,500 metres (11,500 ft) in length. It is used primarily for the generation of hydroelectricity, with an installed power of 1,278 megawatts (1,714,000 hp). It generates on average 560 gigawatt-hours (2,000 TJ) per year. It also serves as a check dam for El Chocón, located upstream.

The reservoir has an area of 38.6 square kilometres (14.9 sq mi) and a volume of 300 million cubic metres (11×10^9 cu ft). Its depth is 7.7 metres (25 ft) on average (maximum: 15 metres (49 ft)).
