From the "AGREEMENT that updates the average annual availability of the surface national waters of the 757 hydrological basins that comprise the 37 hydrological regions in which the United States of Mexico is divided", published in the Official Gazette of the Federation on 07 July 2016, it is clear that in the 9 hydrological basins of Hydrological Region Number 14 Ameca, there are volumes that can be exploited, but it is important to carry out an adequate management of these volumes giving priority to the current and future demands of domestic and urban public use, and provide volumes for environmental use or for ecological conservation, in order to contribute to the sustainability of this región of México.
