Lake Amatitlán

Lake Amatitlán is a volcanic lake in south-central Guatemala located less than 20 kilometers south of Guatemala City and adjacent to the town of Amatitlán. It is a prominent local waterbody used historically for fishing, boating and recreation.

The lake is notable for having experienced severe water-quality degradation in the modern era, with eutrophication and pollution affecting aquatic life and recreational use. Efforts to monitor and remediate the lake have been ongoing at municipal and national levels.

The lake formed in a tectonic-volcanic landscape and has long been an economic and recreational resource for surrounding municipalities. Urban growth on the lake’s northern shore has been a principal driver of water-quality issues.

Lake Amatitlán sits in a basin south of Guatemala City within the Guatemala Department, surrounded by towns and agricultural land with the volcanic highlands rising nearby.

• Proximity to capital: Closest major urban center is Guatemala City; the lake is often accessed from towns on its northern shore for day trips and local recreation.
• Environmental status: The lake has experienced serious pollution and eutrophication pressures from urban and industrial sources, affecting water quality and fisheries.
