The lakes, saltpans and lagoons existing in the region are formed by the stagnation of the rains that fall during the summer in the high plateau.
Likewise, the climatic conditions, as well as the soil characteristics, do not allow a development and the constant dripping of important water flows.
In the high plateau are the Caquena and Lauca river, which waters flow into Bolivian territory. Also, in this same one, the Cotacotani lagoons have as affluents the Benedicto morales river and the El Encuentro brook.
In the sector of the Tarapaca Plateau (intermediate depression) the Lluta river and some water flows are developed going through the Camarones, Vitor y Azapa Creek that, occasionally, reach the sea. These small rivers have permitted the practice of agriculture in the oasis, which consists, mainly in legume, citric and olives cultivation.
