Today we're going to introduce a river that's quite well-known worldwide, being the largest river in Venezuela: the Orinoco River . There are many fascinating legends about this river, involving monsters and other strange creatures. It boasts a wealth of minerals, ecological richness, and abundant water resources, and thanks to it, the civilizations that thrived along its banks were able to flourish.
We explain everything related to the Orinoco River.
Location and length
The name of the Orinoco river comes from one of the most primitive indigenous tribes of Venezuela. This tribe has already disappeared today due to the floods that have happened over the years.
As mentioned, it is located in Venezuela, in the state known as Amazonas. Much of this area is influenced by the Guaviare River, which forms the border with Colombia. It is considered the largest river in the country. In its final stretch, it joins the Amazon River at its mouth.
This powerful river has a total length of 2.140 kilometers and is considered not just a river, but a complete system. If we also take into account the confluence with the Guavir River, the total length is 2.800 kilometers. This makes it one of the largest rivers on the planet.
The delta is so large that, when it was discovered, it was thought to be a sea. The basins are also enormous, carrying a vast volume of water. The Orinoco basin has more than 436 smaller rivers and 2000 streams. These streams are the natural influx of water that flows into the river basin and contributes to the overall flow. All of this water eventually empties into the Atlantic Ocean.
The total size of the basin is quite difficult to measure, but it is estimated that it may have a total of 990.000 square kilometers, of which 643.480 km2 are located in the territory of Venezuela. The dimensions of this basin make it the third largest in all of South America.
Importance of the Orinoco River
The basin is of great importance to Venezuela, not only historically, but also economically. It has served as a vital waterway for the transport of various goods from city to city. This has allowed for the expansion of communities that settled along the river, thus increasing the population in these areas.

It also has great ecological importance given that it has large areas with abundant animal and plant species. The ecological value lies in the abundance and the prosperous climate that it has. There are many vegetables that are used for the conservation of the place thanks to its tourist attraction. As expected, something natural acquires its maximum economic value when other economic activities can be extracted from it. For example, various protected areas have an entry fee and thereby earn money and increase their value. Therefore, in their entirety they make the Orinoco River of great value in all aspects.
However, now that open-pit mining is permitted, various environmental impacts are emerging that are degrading the area's environmental value. These impacts include not only soil contamination, habitat destruction, and water degradation, but also contributing to the effects of climate change, which are exacerbated in this region by the El Niño phenomenon.
Mouth and tributaries
The Orinoco River's mouth was documented by Christopher Columbus himself in 1498. Venezuelan beaches encompass the majority of the river's mouth. A delta forms, stretching over 300 km along the coast. This is a vast phenomenon, and numerous geological forces act to modify its topography.
The mouth extends from Punta playa through the eastern area to the Boca Bagre area. Being so extensive, the first explorers that Columbus found himself doubted whether they had discovered a new sea. It has more than 300 channels and the powerful Delta that it forms has a size of 30.000 km2.
Your complete tour begins in the Venezuelan Amazon and in the highest areas of the Amazon State. When it reaches a point called La Esmeralda it joins the Casiquiare River and travels 290 km where the Negro River joins, which is also a tributary of the Amazon.
One of the main tributaries is the Ventuari River , which begins its journey to the city of San Fernando de Atabapo. It is there that it begins to receive the waters of the Guavira River, mentioned earlier, and marks the natural border between Venezuela and Colombia. Other well-known tributaries that contribute significantly to the Orinoco River include the Caura-Merevari, the CaronÃ-Cuquenán, the Vichada, the Meta, and the Arauca.
Ecological and economic value
Since many areas along this river are exploited for resources, it takes on great economic and ecological importance. The forested area is exploited to obtain mineral wealth such as steel and aluminum.
Mining areas are also found where the Orinoco River meets other tributaries such as the Caronà and Cerro BolÃvar. These areas contain large iron ore deposits that contribute to the development of the region's industry. Furthermore, all this economic activity is linked to the historical and current importance of the Ebro River in the region.
There is also an oil extraction margin on the left side, adjacent to the states of Monagas and Anzoátegui. This oil is taken to the city of El Tigre where it is used. The way oil is transferred from one place to another is done through pipelines of different sizes.
Thanks to the Orinoco River's large flow, major cities have been able to build mining operations and hydroelectric plants, where a comprehensive economic exploitation plan is implemented.

As you can see, the Orinoco River is of great importance worldwide.
