===Rivers and other bodies of water===

Mexico has nearly 150 rivers, two-thirds of which empty into the Pacific Ocean and the remainder of which flow into the [[Gulf of Mexico]] or the [[Caribbean Sea]]. Despite this apparent abundance of water, water volume is unevenly distributed throughout the country. Indeed, five rivers—the [[Usumacinta River|Usumacinta]], [[Grijalva River|Grijalva]], Papaloapán, [[Coatzacoalcos River|Coatzacoalcos]], and [[Pánuco River|Pánuco]]—account for 52 percent of Mexico's average annual volume of surface water. All five rivers flow into the Gulf of Mexico; only the [[Río Pánuco]] is outside southeastern Mexico, which contains approximately 15 percent of national territory and 12 percent of the national population. In contrast, northern and central Mexico, with 47 percent of the national area and almost 60 percent of Mexico's population, have less than 10 percent of the country's water resources.

In 2024, a team of oceanographers discovered the world's deepest blue hole, [[Taam Ja' Blue Hole|Taam Ja]], meaning 'deep waters' in [[Mayan languages|Mayan]], in Chetumal Bay, [[Mexico]]. Due to technical limitations, the actual depth of the hole is still unknown. However, the findings suggest the presence of a complex labyrinth of underground caves and tunnels, which could shed new light on the site and the diversity of life within it.<ref>{{Cite web |last=Cohen |first=Li |date=2024-05-01 |title=Researchers found the planet's deepest under-ocean sinkhole — and it's so big, they can't get to the bottom - CBS News |url=https://www.cbsnews.com/news/deepest-blue-hole-ocean-sinkhole-mexico-chetumal-bay/ |access-date=2024-05-12 |website=www.cbsnews.com |language=en-US}}</ref>
