The Lempa River (Spanish: Río Lempa) is a 422 km long river in Central America.[2] Its sources are located in between the Sierra Madre and the Sierra del Merendón in southern Guatemala, near the town of Olopa.[2] In Guatemala the river is called Río Olopa and flows southwards for 30.4 km before entering Honduras and changing its name to Lempa river at 14°32′52″N 89°15′50″W / 14.547700°N 89.264002°W. In Honduras it flows through Ocotepeque Department for 31.4 km, and crosses the border with El Salvador at the town of Citalá (14°22′19″N 89°12′45″W / 14.371857°N 89.212439°W) in the department of Chalatenango. The river continues its course for another 360 km in El Salvador, flowing in a generally southwards direction until it reaches the Pacific Ocean in the department of San Vicente.[2][3] The river forms a small part of the international boundary between El Salvador and Honduras.
The river's watershed has an extension 18,246 km², of which 10,255 km2 (56%) is situated in El Salvador, 5,696 km2 in Honduras and 2,295 km2 in Guatemala.[1] 49% of El Salvador's territory is covered by the Lempa river basin,[1] and 77.5% of the Salvadoran population lives in cities, towns, and villages that are located in its basin, including the capital city of San Salvador.[3]
Hydroelectricity
There are several hydroelectric dams along the river. In El Salvador there is the Guayojo dam, the Cerrón Grande Hydroelectric Dam, the 5 de Noviembre dam, and the 15 de Septiembre dam which can be easily seen from the Pan-American highway.
