Vaciabotas Dam
This is the dam or weir where the Caz del Molino takes its water from the Tajuña River. It is also known as the Azud del Molino and is one of the irrigation channels of the Madrid plain. The dam's waterfall is next to the old Molino Nuevo or Molino de la Isla, which is privately owned and documented in the Topographic Relations of Felipe II. The riverbank is a cool environment of giant trees and riverside vegetation. The irrigation channel and the course of the Tajuña are separated by the dam and until they meet again at the Puente del Palo they form the island that gives the place its name. In the area of Tielmes there are the Presón weirs, the Presa del Marqués and the Cantarranas Molino waterfall, all of Islamic origin.
