Bodies of Water

The Gulf of Mexico: A Sea Shared by Latin America

In the warm waters between the Yucatán Peninsula and the Florida Keys lies one of the world's most economically and ecologically significant ocean basins. The Gulf of Mexico encompasses 1.6 million sq km (615,000 sq mi) of ocean bordered by three nations—Mexico, Cuba, and the United States—and has shaped the destiny of all three for centuries, supporting extraordinary biodiversity while fueling energy industries, fisheries, and coastal economies throughout the region.

The Iguazú River: A Natural Wonder of South America

The Iguazú River is one of South America's most consequential waterways, not only for the world-famous falls that bear its name but for the long course it travels beforehand through the landscapes of Brazil and Argentina. Originating in the Serra do Mar coastal range, the river winds westward for well over a thousand kilometers, supporting diverse ecosystems and regional communities, before culminating in the dramatic cascades of Iguazú Falls.

The Lempa River: Central America's Lifeline of Nature and Culture

Flowing through the heart of Central America, the Lempa River is a vital artery that sustains the landscapes, economies, and communities of three nations: Guatemala, Honduras, and El Salvador. As the longest river in El Salvador, it holds immense significance in the region, shaping its environment, history, and cultural identity. The river's diverse ecosystems, historical importance, and economic contributions make it a subject of considerable interest and a focal point for conservation efforts.

The Lerma River: Mexico's Lifeline and Environmental Challenge

The Lerma River is a significant watercourse within the intricate network of Mexico's waterways, known for its length and crucial role in the Lerma-Chapala basin. Originating near Toluca, this river meanders through diverse landscapes, traversing the states of Mexico, Queretaro, Michoacán, and Guanajuato before emptying into Lake Chapala. The river ranks as the country's second-longest, shaping the ecosystems and livelihoods of millions of people along its course.

The Lifeblood of Eastern Cuba: The Cauto River

The Cauto River, Cuba's longest and most significant river, winds through the island's eastern region, sustaining ecosystems, agriculture, and communities. As a vital freshwater source, the river plays an essential role in shaping the landscapes and livelihoods of the provinces it traverses. With its diverse ecosystems, economic importance, and cultural significance, the Cauto River is a natural treasure that embodies the interplay between nature and human activity in Cuba.

The Madre de Dios River: Gateway to the Amazon Basin

The Madre de Dios River, a vital headwater tributary of the Amazon River, forms an essential part of the Amazon River drainage basin and plays a crucial role in the geography and ecology of Peru and Bolivia. The river, originating in the Andes, flows through vast stretches of tropical rainforest, providing transportation, sustenance, and a lifeline for the sparse populations living along its banks. The river's basin is home to significant biodiversity and supports a variety of ecosystems while also serving as an essential route for the region's Indigenous peoples.

The Magdalena River and Basin: Colombia's Lifeline

Flowing gracefully through the heart of Colombia, the Magdalena River is the country's principal waterway, weaving from the towering peaks of the Andes to the shores of the Caribbean Sea. Carving a path through diverse landscapes and ecosystems, this mighty river and its expansive basin serve as Colombia's lifeblood, nurturing vibrant communities, sustaining vital ecosystems, and running through the center of the nation's history and literature.

The Maipo River: Lifeline of Central Chile

The Maipo River flows from the western slopes of the Andes to the Pacific Ocean, providing approximately 80% of Santiago's freshwater supply for seven million people. The river's basin contains more than 800 glaciers that store critical water during dry summer months. However, climate change has driven dramatic glacier retreat. This vital river system faces mounting pressures from prolonged drought, urban expansion, and agricultural demands, threatening water security for millions while supporting agriculture and industry.

The Marañón River: The Lifeblood of the Amazon's Upper Basin

Known as the "Grand Canyon of the Amazon," the Marañón River in Peru is one of South America's most significant waterways. As a principal tributary of the Amazon River, the Marañón shapes the region's geography and serves as a cradle of biodiversity and cultural heritage. It traverses diverse landscapes, from Andean highlands to tropical rainforests, playing a vital role in the ecological and economic life of the region.

The Orinoco River: South America's Arc of Life

The Orinoco River rises in the Parima Mountains of southern Venezuela and sweeps in a great arc through Venezuela and Colombia before spreading into a vast delta on the Atlantic coast. It is the third-largest river on Earth by discharge and a homeland for peoples such as the Warao, Piaroa, Ye'kwana and Yanomami. Its basin shelters river dolphins, giant otters and the critically endangered Orinoco crocodile, and it now faces mining, mercury contamination and oil-industry pressures that put much of that richness at risk.
