The Pontón de la Oliva is a Spanish dam located in the Ayllón mountain range, northeast of the Community of Madrid and northwest of the province of Guadalajara. It was built in 1857 and is currently disused. This dam is the sixth and last in the course of the Lozoya River, and is the oldest of the entire system of dams and canalizations of the Canal de Isabel II. This canal supplies drinking water to Madrid and a large part of the community. The height of the Pontón de la Oliva Dam is approximately 30 meters. If you are interested in exploring the area, there are routes that take you to the Cárcavas de Pontón de la Oliva, a curious geological formation in the Community of Madrid. In addition, you can enjoy a route along the Pontón de la Oliva to the Lozoya River, which offers impressive views. I hope you find this information interesting! 😊

The La Parra weir is a Spanish reservoir located in the bed of the Lozoya River, in the province of Madrid.

Built under the reign of Isabel II, it is the oldest dam in Madrid, being the last on the course of the Lozoya River. This dam, 27 meters high, made of limestone, was inaugurated in 1856 as the beginning of the water supply project for Madrid, the new capital of the kingdom of Spain, which was growing considerably in population. Currently disused due to permeability problems caused by the poor choice of its location, today it belongs to the historical heritage of the Sierra de Ayllón, being a place visited by climbing enthusiasts and traveled by hikers and cyclists.

The Cañada de la Caleriza is a winding path that runs along the banks of the Lozoya River. This section coincides with the beginning of the GR 88, which runs through the provinces of Madrid, Segovia and Guadalajara. The Lozoya is a tributary of the Jarama along whose 91-kilometer route six reservoirs have been built.

Dam with the aim of controlling the pressure that the Navarejos dam can suffer.
