Ingeniero Ballester Dam
The Ingeniero Ballester Dam is a dam on the Neuquen River, in the Argentine Patagonia. The top of the dam doubles as a road bridge. The dam is located near the town of Barda del Medio, province of Rio Negro, downstream from the El Chanar Dam (the last part of the Cerros Colorados Complex), and 25 kilometers from north-northeast from the city of Neuquen.
The dam is used to re-route part of the flow of the Neuquen River to a long irrigation canal which flows east and then southeast passing by the cities of Barda del Medio, Cinco Saltos, Cipolletti, Allen, General Roca, Ingeniero Luis A. Huergo, and Villa Regina, and then emptying into the flood plain of the Rio Negro. A second derivation dam, dowstream on the canal, sends water to feed the reservoir of the Pellegrini Lake.
The Ballester Bridge over the dam is 400 meters long and 5 meters wide. National Route 151 crosses over it from Rio Negro to the province of Neuquen.
