The construction of the dam began in 1974 and was completed in 1979. Power is generated by fourteen Kaplan turbines, totaling the installed capacity to 1,890 MW (2,530,000 hp). The dam passes approximately 64,000 cubic metres (2,300,000 cu ft) of water per second, compared to the current average flow of the Uruguay River at 4,622 cubic metres (163,200 cu ft). The reservoir has a total area of 783 square kilometres (302 sq mi), while its maximum dimensions are 140 by 9 kilometres (87.0 mi × 5.6 mi).[1][2]
