What are some rivers and mountains in El Salvador?

El Salvador is located in Central America. It has a total area of 8,123 square miles (21,040 km²), making it comparable in size to, although slightly smaller than, the state of Massachusetts. El Salvador is the smallest country in continental America. Due to its size it is affectionately called the "Tom Thumb of the Americas". It has 123.6 square miles (320 km²) of water within its borders. Several small rivers flow through El Salvador into the Pacific Ocean, including the Goascorán, Jiboa, Torola, Paz and the Río Grande de San Miguel. Only the largest river, the Lempa River, flowing from Honduras across El Salvador to the ocean, is navigable for commercial traffic. Volcanic craters enclose lakes, the most important of which are Lake Ilopango (70 km²/27 sq mi) and Lake Coatepeque (26 km²/10 sq mi). Lake Güija is El Salvador's largest natural lake (44 km²/17 sq mi). Several artificial lakes were created by the damming of the Lempa, the largest of which is Embalse Cerrón Grande (350 km²/135 sq mi).
