Geological formation

Hydrography of the lake

Laguna de Sayula is a wetland with Ramsar (an important place for bird conservation), the wetlands are ecosystems where water is the main factor controlling the environment, vegetable life and animals associated with it. The lakes of the closed Sayula-Atotonilco basin form part of the endorheic lakes of the neo-volcanic axis. But Laguna de Sayula is especially important because of its relation to the migratory habitats of the North American birds.
