Water is one of the Park’s main assets; it forms a high capacity hydrographic basin formed by 35 rivers (16 of which originate in the Park) with a flow rate that feeds the flatlands and valleys of the Cesar and Ariguaní rivers as well as an extensive semi-arid zone of La Guajira, especially the valley of the Rancheria river, backbone to the Wayuu people. It is also a source for the aqueducts that provide water to almost 1.5 million inhabitants of several main cities in the area and also for the agribusinesses of banana, palm, rice, and cotton, for livestock raising and for the touristic sector.
