Falcon Dam

Falcon Dam (Template:Langx) is an earthen embankment dam on the Rio Grande between Starr County in the U.S. state of Texas and the city of Nueva Ciudad Guerrero in the Mexican state of Tamaulipas. The dam was built for water conservation, irrigation, hydroelectric power generation, flood control, and recreational purposes and as an international border crossing between Zapata and Starr Counties and Tamaulipas. Construction on the dam began in December 1950 and ended in April 1954 but it was dedicated by Mexican President Adolfo Ruiz Cortines and U.S. President Dwight D. Eisenhower in October 1953.

Construction

The Falcon Dam was authorized by the Treaty relating to the utilization of waters of the Colorado and Tijuana Rivers and of the Rio Grande or Water Treaty of 1944 between Mexico and the United States. Construction on the dam began on 15 December 1950 and the reservoir began to fill on 25 August 1953. The dam was dedicated on 19 October 1953 and work was officially complete on 8 April 1954. By October 1954, the dam's hydroelectric power station began to produce electricity.

The U.S. Power Station

The Falcon Dam is a Template:Convert high and Template:Convert long earthen embankment dam. The dam is made of Template:Convert of earth-fill, Template:Convert of concrete and Template:Convert of reinforced steel. The center of the dam is over-topped with a Template:Convert long spillway with widths ranging from Template:Convert at the top and Template:Convert at the bottom. The spillway is controlled by six Template:Convert fixed wheel gates and can release up to Template:Convert downstream.

The Falcon Dam supplies water to two different hydroelectric power plants, one on the Mexican side and another on the U.S. side. Each power plant contains 3 x 10.5 MW Francis turbine generators for a combined total of 63 MW. Each power plant also receives water from the reservoir via 4 x Template:Convert diameter penstocks. The two extra penstocks are for an additional generator if needed.

The Falcon Dam created the Falcon International Reservoir that has a volume of Template:Convert and a surface area of Template:Convert.

Border crossing

The Falcon Dam Port of Entry is a port of entry at the Falcon Dam to the United States on the Mexican border. It is essentially a replacement for the former Zapata Port of Entry, which was situated at a bridge in the town of Zapata, Texas. When the dam was completed, the town was moved to higher ground, and the Zapata Bridge now lies at the bottom of Falcon Lake.

2010 Plot

In June 2010, U.S. authorities revealed that the Los Zetas drug cartel had planned to destroy the Falcon Dam to terrorize the rival Gulf Cartel, which smuggles drugs in the area. Small amounts of dynamite discovered near the dam and a copy of a warning helped alert authorities. A larger U.S. and Mexican security presence in the area may have thwarted the attack that Los Zetas had reportedly warned civilians about on the Mexican side of the border.
