Miguel Alemán Dam
MCM (with Cerro de Oro Dam
)
Surface area47,800 hectares

The Miguel Alemán Dam is on the

Miguel Alemán Lake
with an area of 47,800 hectares. The dam operates in conjunction with the
Papaloapan basin in Veracruz
state. Together with the 22,000 hectare reservoir of the Cerro de Oro, which is joined by a channel to the Miguel Alemán Lake, the combined capacity is 13,380 
million cubic metres.[1]
The lake formed by the dam is scenic, providing income from fishing and tourism. The northwestern shore and islands have been declared a nature reserve.[2] The dam includes the Temascal hydroelectric plant.

Purpose

The Santo Domingo and the Tonto rivers join to the south of the city of San Juan Bautista Tuxtepec to form the Papaloapan river, which meanders northeastward to the Gulf of Mexico. The basin of this river in the coastal plain was subject to frequent flooding, with the damage sometimes compounded by cyclones. A particularly severe flood in September 1944 covered 470,000 hectares, with great loss of life and property. The Miguel Aleman dam reduced the problem, although floods continued and the Cerro de Oro Dam on the Santo Domingo was required to fully control the floods.[3]

Construction and capacity

The dam was initiated by the government of President Miguel Alemán Valdés in 1947 and construction started in 1949. The dam was named for the president's father, Miguel Alemán González.[4] The dam created a 2,300,000-acre (9,300 km2) reservoir, provided a large portion of the region's growing electricity demand and provided an assured irrigation supply for thousands of new fruit, dairy, and vegetable farms.[5] However, the project required relocation of thousands of poor

Chinantec and Mixe families.[5] There been a re-evaluation of the project's impact on the environment.[6]

The dam has a capacity of 8 million m3 (2,113,400,000 US gallons), from which 6.77 million m3 (1,788,500,000 US gallons) is available for power generation. The dam has a length of 830 meters (2,720 feet). The Temascal hydroelectric plant located east of the dam generates about 725 million kilowatts a year.[7]
