 Nowadays, with the expansion of urban areas and the need to find fresh water deposits by the Mexican population, some of the rivers and springs in the park are recklessly exploited.Starting from the watercourses which are fed from the springs that flow into the Desierto de los Leones, two of the most important rivers of the Valley of Mexico originate in the park, the Mixcoac River and Rio Hondo, which are fed by the water of other streams that form the Agua de Leones Stream.There are three main water currents that flow through the hillsides which also establishes the park boundaries.
