The Malpaso Dam, officially known as the Nezahualcóyotl Dam, is located in the Centro region of Chiapas, Mexico near the border with Tabasco and Veracruz. It was the first of several major dams built on the Grijalva River to generate hydroelectric energy and has the second largest reservoir in Mexico, after the Belisario Dominguez Dam. Construction of the dam occurred in the 1960s and flooded not only the riverbed but also hectares of rainforest and farmland, various towns and villages and archeological sites. These include the former town of Quechula, whose 16th century Dominican church will appear when water is at low levels, and the archeological site of San Isidro which contains one of only two known double Mesoamerican ball courts. Commissioning of the dam's 1,080 MW power station began in 1969 and ended in 1977. The reservoir and later construction of a federal highway has spurred ecotourism in the area.
