The Malpaso Dam, officially called the Nezahualcóyotl Dam , stands in the central region of Chiapas , Mexico near the border with Tabasco and Veracruz . It was the first of several larger dams that were built on the Río Grijalva for the purpose of generating hydropower . It has the second largest reservoir in Mexico after the La Angostura Dam .

Reservoir

The reservoir flooded large areas of rainforest and farmland, various cities, villages and archaeological sites, including the city of Quechula , whose 16th century Dominican church emerges from the lake when the water level is low, and San Isidro with an old Mesoamerican ball playground . Hundreds of families had to be relocated for the reservoir ; they now live in Nuevo Quechula. The reservoir and the later construction of a motorway with the Chiapas bridge crossing the reservoir have promoted ecotourism in this region.

Hydroelectric power plant

The hydroelectric power plant with its six 180- MW - Francis turbines (together 1080 MW) was put into operation from 1969 to 1977.

Flood protection

The dam, together with the smaller Peñitas dam, also serves to protect the state of Tabasco from flooding .
