Lozoya (river) - Water Use

Water Use

The Lozoya has been affected by the construction of several dams and reservoirs that supply almost 50 percent of the water for Madrid's metropolitan area. In fact, 50 percent of the river's length is taken up by reservoirs. Other uses of the river water such as forestry and agriculture have had much less physical impact. Because the impact of construction on the Lozoya has been so great, the river is now rated as Heavily Modified Water Body (HMWB) based on the European Synthesis Project.
