Hydrology

Hydrology, rivers, and dams.

The hydrographic network that reaches the El Arenal River begins at the Tortugas Dam, where the Santa Cruz del Astillero River flows into it, and it continues its path to El Arenal and exits the municipality.

The municipality is located in the hydrological region RH-12 Lerma-Chapala-Santiago River, Basin E Santiago-Guadalajara River, and in Sub-basin C Verde-Santa Rosa Dam Rivers.

The most important watercourses are the Arenal and Salado Rivers, along with the streams Arenal, Agua Dulce, El Saucillo, and El Ganado. The watercourses and bodies of water, whether perennial or seasonal, impose constraints on urban development, and their federal servitude must be respected to prevent risks. Likewise, their pollution should be avoided.
