The El Quimbo Dam is a concrete faced rock-fill dam (CFRD) and hydroelectric power facility in the Huila Department of southwestern-central Colombia, approximately 69 kilometres (43 mi) south of the city of Neiva, on the Magdalena River. It is located about 1,300 metres (4,300 ft) upstream from the confluence of the Páez River with the Magdalena River. Its works were officially opened on February 25, 2011 in the presence of President Juan Manuel Santos. It is one of the largest infrastructure projects in the country. The project was completed 4 years later, in the end of 2015.
