Magdalena River

The Magdalena River (Spanish: Río Magdalena, Spanish pronunciation: [ˈri.o maɣðaˈlena]; Less commonly Rio Grande de la Magdalena) is the principal river of Colombia, flowing northward about 1,528 kilometres (949 mi) through the western half of the country. It takes its name from the biblical figure Mary Magdalene. It is navigable through much of its lower reaches, in spite of the shifting sand bars at the mouth of its delta, as far as Honda, at the downstream base of its rapids. It flows through the Magdalena River Valley.

Its drainage basin covers a surface of 27.3 million hectares (105,000 sq mi), which is 24% of the country's area and where 66% of its population lives.

Course

The headwaters of the Magdalena River are in the south of Colombia, where the Andean subranges Cordillera Central and Cordillera Oriental separate, in Huila Department. The river then runs east of north in a great valley between the two cordilleras. It reaches the coastal plain at about nine degrees north, then runs west for about 100 km (62 mi), then north again, reaching the Caribbean Sea at the city of Barranquilla in the zone known as Bocas de Ceniza.
