The 'Apure River' is a river of western Venezuela, formed by the confluence of the Sarare and Uribante near Guasdualito, in Venezuela, at . Most of the streams that ultimately form the Apure originate in the Venezuelan highlands of the Cordillera de Mérida and only some minor affluents of the Sarare River come from the Cordillera Oriental in the Colombian Andes, entering Venezuela at the confluence with River Oirá which has a very narrow and steep valley and forms the border line between the two countries for a distance of 41 km. River Oirá starts in Venezuela and its thalweg forms that border for several kilometres downstream. River Uribante is a longer river than the Sarare and flows from the Táchira-Mérida border, near the town of Pregonero. The length of the Uribante River should be added to the Apure, the same way it has being done with many rivers in the world. At the point where the two rivers join, the Apure flows eastward across the Venezuelan llanos, into the Orinoco. Its drainage area thus includes the slopes of both Colombian (less than 0,5 % of its total area) and Venezuelan Andes.
The Apure flows primarily through Apure State including San Fernando before joining the Orinoco River via six braided river branches west of Cabruta, Guárico State, across from Caicara, Bolívar State, at about . The Apure is 645 miles long from the Uribante's starting point to the Orinoco. It is navigable for about 500 miles above the Orinoco, where it has a sluggish course across the llanos, despite rapids at about the 110 mile mark. From the north, its principal tributaries are the Caparo, Portuguesa and Guarico. The Caucagua is its only major tributary from the south. Because of the flatness of the land its meanders and bayous to the south are mingled with those of the Arauca River creating an extensive area which is flooded annually. However, both rivers keep independent channels during dry season.
