Downstream, the Nazas River eventually reaches the Laguna de Mayran, an important wetland ecosystem that provides habitat for migratory birds and diverse aquatic species. Effective wastewater treatment is essential to prevent nutrient pollution and maintain the ecological health of this sensitive arid-land watershed.
