The Motagua River (Spanish pronunciation: [moˈtaɣwa]) is a 486-kilometre (302 mi) long river in Guatemala.[1] It rises in the western highlands of Guatemala where it is also called Río Grande, and runs in an easterly direction to the Gulf of Honduras.[2] The final few kilometres of the river form part of the Guatemala/Honduras border. The Motagua River basin covers an area of 12,670 square kilometres (4,890 sq mi) and is the largest in Guatemala.

Overview

The river runs in a valley that has the only known source of jadeitite (jade) in Mesoamerica, and was an important commerce route during the Pre-Columbian era. The important Maya site of Quirigua is near the river's north bank, as are several smaller sites with jade quarries and workshops.

The Motagua river valley also marks the Motagua Fault, the tectonic boundary between the North American and the Caribbean Plates. The Motagua fault has been the source of several major earthquakes in Guatemala. Much like Lake Amatitlán, the river is highly polluted with untreated sewage, industrial waste, tons of sediment (garbage) and blackwater from Guatemala City.
