Valle de Sarmiento
Valle de Sarmiento (or Sarmiento Valley, also known as the Valley of the Senguer River) is an irrigated agricultural valley spanning 42,000 ha located in the south-central part of Chubut Province, forming an oasis in the midst of the Patagonian Plateau, where the greatest temperature variations in Argentina are recorded. It is situated in the center of the Sarmiento Department, between Lake Musters and Lake Colhué Huapi, in the area known as the Gran Bajo de Sarmiento.
Its location was strategic, as it lies in an oasis area of the Patagonian Plateau, where an arid climate predominates, with annual precipitation below 200 mm. The local population was able to supply the growing population of Comodoro Rivadavia with food and raw materials via the Comodoro Rivadavia Railway. This ensured greater overall traffic than that on the Puerto Deseado to Colonia Las Heras branch and increased commerce for the area. The productive towns of Sarmiento and Colhué Huapi thrived, continuing to supply Comodoro Rivadavia.
The valley, south of Musters and Colhué Huapi lakes, is one of the southernmost irrigated oases in the world. Here, forage crops (mainly alfalfa), fruit trees, and vegetables are cultivated.
