Lake Zumpango (Spanish: Laguna de Zumpango; Nahuatl: Tzompanco, “string of scalps”) is an endorheic basin situated in the northern part of the Valley of Mexico. The lake lies primarily within the municipality of Zumpango and extends into the adjacent municipality of Teoloyucan, in the State of Mexico, approximately 35 mi (55 km) north of Mexico City. Its geographic coordinates are 19° 16′ 01″ N, 98° 58′ 59″ W.
Geography
Lake Zumpango was historically the northernmost of five interconnected lakes that once covered the Valley of Mexico—alongside Lakes Xaltocan, Xochimilco, Chalco, and Texcoco—forming a contiguous freshwater system of roughly 1 500 km² (580 sq mi). Unlike exorheic lakes, its waters have no natural outlet to the ocean; instead, water entered and left the basin primarily through evaporation and, historically, through artificial drainage projects.
History
Pre‑Columbian period – Archaeological evidence indicates settlements along the lake’s shores dating from 200 BC to 100 AD, reflecting its importance to early Mesoamerican cultures that inhabited the valley, including the peoples associated with Teotihuacan, the Toltec, and later the Aztec Empire.
Spanish colonial era – Following the Spanish conquest, the authorities began large‑scale drainage of the valley’s lakes to mitigate flooding in Mexico City. In the early 17th century, engineer Enrico Martínez directed the construction of the Nochistongo Canal, which diverted water from Lake Zumpango northward toward the Tula River. A subsequent “Grand Canal” was added, but the drainage efforts were insufficient to prevent the catastrophic flood of 1629. Over subsequent centuries, continued drainage and urban expansion reduced the lake’s inflows, leading to a decline in water level and quality.
Modern period – By the late 20th century, Lake Zumpango had become heavily polluted with sewage and solid waste. Recent municipal initiatives have aimed to improve water quality and restore parts of the lagoon, though challenges persist.
Ecology
The lake historically supported a diverse wetland ecosystem, including the axolotl (Ambystoma mexicanum), an endemic amphibian now classified as critically endangered due to habitat loss throughout the former lake system. Restoration efforts seek to preserve remaining native flora and fauna.
Hydrology
As an endorheic basin, Lake Zumpango’s water balance is governed by precipitation, surface runoff, evaporation, and human‑controlled drainage. The lake’s current depth and surface area are substantially reduced compared with its pre‑colonial extent.
