Hydrology
The Comarca Lagunera is subject to several period floods due to the overflowing of its principal rivers.
Nazas River
The
Nazas River, average flow of 1,900 cubic meters per second, is formed from the merging of the
Sextín River and the
Ramos River. In its transit towards the
Laguna de Mayrán it's contained in the
Lázaro Cárdenas dam (3,336 million cubic meters). In its course it receives the flows of the
Vizcaíno,
Peñón,
San Juan,
Naitcha and
Cuencamé creeks, and finally stops at the
Francisco Zarco Dam (436 million cubic meters).
Aguanaval River
The
Aguanaval River, which has an average flow of 600 cubic meters per second, is formed from the fusion of the
Saín Alto River and
Trujillo River in Zacatecas. It receives the flows of the
Reyes,
Santiago and
Mazamitote creeks.
Other
There are other important hydrologic components in the Comarca Lagunera region. The
Benjamín Ortega Cantero dam in the municipio of Mapimí, the
Francisco González de la Vega dam in Rodeo, the
Los Naranjos dam in Simón Bolívar and the
Cinco de Mayo dam in San Pedro del Gallo.
Also, the Mayrán and Viesca lagoons are big natural dams that constitute dry beds at the moment, and are unable to be filled due to the dams located in the Nazas River for the Mayrán lagoon and the city of
Matamoros being in the Aguanaval River's flood path.
