Lake Amatitlán (Lago Amatitlán, Spanish pronunciation: [laɣo amatiˈtlan]) is a volcanic lake in south-central Guatemala, fairly close to Guatemala City. It lies in the central highlands, 1,186 m (3890 feet) above sea level.[2] Its maximum depth is 33 m (108 feet) and an average of 18 m (59 feet). The lake is 11 km (7 miles) long and 3 km (2 miles) wide; with an area of 15.2 square kilometers (5.9 sq mi) and a water volume of 0.286 cubic kilometers.

The lake's primary inflow is the Villalobos River, and the lake is drained by the Michatoya River, an important tributary of the María Linda River. The town of Amatitlán is situated at the head of the Michatoya river. A dam with a railway on top was constructed at the narrowest point, thus effectively dividing the lake into two water bodies with different physical, chemical and biological characteristics: a north-western and a south-eastern basin.

The lake is used as a water source, for navigation and transportation, sightseeing and tourism (10,000 visitors annually), recreation (swimming, sport-fishing, water skiing, yachting) and fisheries.

History

As of 1850, the lake was used as a bathing lake and a resort area in the spring. Nearby hot springs were also popular with visitors.[3]

Economy

In the mid 19th century, the lake was plentiful with crawfish, sardines, and other seafood. The seafood was captured and sold for the local region, as seafood was rarely imported into the area.[3]

Pollution

Amatitlán lake's catchment area includes Guatemala City. Each year large quantities of untreated sewage, industrial waste and a staggering 500,000 tons of sediment are carried into the lake through the Villalobos River.[4] This has contributed to high levels of pollution of the lake's water, and an accelerated eutrophication and siltation.[1][5] This has seriously affected the lake's former function as a source of drinking water and irrigation, and reduced its recreational functions.
