Got this info from Wikipedia
The Orinoco is one of the longest rivers in South America at 2,140 km, (1,330 miles). Its drainage basin, sometimes called the Orinoquia (especially in Colombia) covers 880,000 km²,
76.3% in Venezuela with the rest in Colombia. The Orinoco and its tributaries are the major transportation system for eastern and interior Venezuela and the llanos of Colombia. However, since river navigation is declining in every country, many of the old waterways along the Orinoco watershed are now an obstacle to land communications rather than a useful commercial route.
Major rivers in the Orinoco Basin
Apure: from Venezuela through the east into the Orinoco
Arauca: from Colombia to Venezuela east into the Orinoco
Atabapo: from the Guiana Highlands of Venezuela north into the Orinoco
Caroní: from the Guiana Highlands of Venezuela north into the Orinoco
Casiquiare canal: in SE Venezuela, a distributary from the Orinoco flowing west to the Negro River, a major affluent to the Amazon
Caura: from eastern Venezuela (Guiana Highlands) north into the Orinoco
Guaviare: from Colombia east into the Orinoco
Inírida: from Colombia southeast into the Guaviare.
Meta: from Colombia, border with Venezuela east into the Orinoco
Ventuari: from eastern Venezuela (the Guiana Highlands) southwest into the Orinoco
Vichada: from Colombia east into the Orinoco
In Comparison to Amazon river:
The Amazon River of South America is the largest river in the world by volume, with a total river flow greater than the next eight largest rivers combined. The Amazon, which has the largest drainage basin in the world, accounts for approximately one fifth of the world's total river flow.
