The Meta River is a major left tributary of the Orinoco River in eastern Colombia and western Venezuela, South America. It is formed in the Meta Department, Colombia by the confluence of the Humea, Guatiquía and Guayuriba rivers. It flows east-northeastward across the Llanos Orientales plains of Colombia through an ancient fault. The Meta forms the northern boundary of Vichada Department, first with Casanare Department, then with Arauca Department, and finally with Venezuela, down to Puerto Carreño where it flows into the Orinoco.

The Meta River is 804 kilometres (500 mi) long and its drainage basin is 93,800 square kilometres (36,200 sq mi). The Meta divides the Colombian llanos in two different realms: the western portion on the left is more humid, receives the relatively nutrient-rich sediments from the Andean mountain range and therefore soils and tributaries are also nutrient-rich, while the eastern portion, high plain or altillanura, drains not to the Meta river but to the Orinoco, has a longer dry season and soils and surface waters are oligotrophic (nutrient poor).

The major tributaries of the Meta are the Cravo Sur, the Casanare, the Cusiana, the Upía and the Manacacías.

History[edit]

An 1856 watercolor by Manuel María Paz, of three indigenous people with a boat at Orocué, near the Old Macuco Mission, is an early depiction of life on the river.[1]

Economics[edit]

Starting at Puerto López the Meta becomes navigable, and thus is an important component of the trade across the Colombian and Venezuelan llanos.
