Mexico's largest freshwater lake, resting high on the volcanic plateau between Jalisco and Michoacán.
Lake Chapala
Lake Chapala is the largest natural freshwater lake in Mexico, stretching across the high volcanic plateau where the states of Jalisco and Michoacán meet. Situated at roughly 1,524 meters above sea level and around 45 kilometers southeast of Guadalajara, the shallow lake occupies about 1,100 square kilometers of valley floor and is bordered by a sweep of volcanic sierras, agricultural lowlands, and a long string of lakeside towns.
The lake is fed primarily by the Lerma, Zula, Huaracha, and Duero rivers, and was historically drained by the Río Grande de Santiago toward the Pacific. In modern times, however, heavy urban water demand from the Guadalajara metropolitan area, agricultural draw, sedimentation, and pollution have dramatically reduced inflows. Since 2009, the lake has held Ramsar Wetland status in recognition of its importance to migratory birds, endemic fish, and regional hydrology.
Despite serious ecological pressures, Lake Chapala remains a defining feature of western Mexico. Its shoreline is lined with historic towns and a large expatriate community, and the surrounding basin supports a distinctive endemic fauna, including unique Chirostoma (charal) fish and the rough-footed mud turtle. The lake is at once an ecological landmark, a hydrological resource, and a cultural anchor for the region.
