Lake Titicaca Facts: A High Andean Lake of Islands

Lake Titicaca facts start with a lake that sits high in the Andes, on the border of Bolivia and Peru. It is often called the highest navigable lake in the world, and it stands at a surface elevation of 3,812 m.

The lake is not only high; it is also large. Lake Titicaca is the largest lake in South America, measured by both the volume of water and surface area. In the world ranking, it is the 18th largest lake.

Where is Lake Titicaca, and what makes its shape unusual?

Lake Titicaca is a large lake in the Andes mountains on the border of Bolivia and Peru. Its water body is split into two nearly separate subbasins, and the Strait of Tiquina connects them.

That shape helps explain why the lake has such a varied geography. Lake Titicaca has 41 islands, spread across its high-altitude waters. Among them are islands tied to long histories of living, weaving, and travel on the lake.

Why do people talk about Lake Titicaca water levels?

Lake Titicaca has been experiencing constantly receding water levels since 2000. One sharp drop came between April and November 2009, when the water level fell by 81 cm and reached its lowest level since 1949.

These changes have become part of the lake’s story because its scale is so large and its elevation is so high. The lake’s surface sits at 3,812 m, so the numbers around its water level are closely watched and remembered.

Which animals are closely tied to Lake Titicaca?

Several threatened species are largely or entirely restricted to Lake Titicaca, including the Titicaca water frog and the Titicaca grebe. These species are part of what makes the lake notable beyond its size and altitude.

Lake Titicaca was designated as a Ramsar Site on August 26, 1998. That designation places it among wetland sites recognized for their importance, and the lake’s living world includes species found nowhere else or almost nowhere else.

Who built the floating islands on Lake Titicaca?

The floating islands were built by the Uros people from layers of cut totora. These artificial islands are part of the lake’s human landscape and have long been linked with life on the water.

As of 2011, about 1,200 Uros lived on an archipelago of 60 artificial islands near Puno. That detail gives a clear picture of how many islands and how many people were connected to this way of life.

Taquile is another island with a distinct history. It was used as a prison during the Spanish Colony and into the 20th century, and its textile art was proclaimed a Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO.

What was Lake Titicaca like in wartime history?

In November 1883, the Chilean torpedo boat Colo Colo became the first warship to navigate the lake. That event places Lake Titicaca not only in the story of geography and local culture, but also in military history.

Taken together, these details show a lake with remarkable height, a divided shape, 41 islands, threatened wildlife, floating communities, and a recorded place in history. It is a body of water that has been measured in meters, dates, islands, and human traditions.
