The protected area is important for the region because of the countless sources of water that originate within. The melting water from the glaciers give birth to the rivers that originate in the park and that conform 10 basins and 19 streams of different sizes and characteristics; six of the basins flow into the Magdalena river watershed (Gualí, Lagunilla, Recio, Totare and Coello) and the remaining four (Chinchiná, Campoalegre, Otún and Quindío) into the Cauca river watershed. This hydrographic web provides water for 2 million inhabitants in the coffee-growing region.
