Lake Titicaca
Puno
Lake Titicaca is a vast high-altitude lake situated in the Andes mountains, bordering Peru and Bolivia. It holds the distinction of being the highest navigable lake in the world, with a surface elevation of approximately 3,812 meters (12,507 feet). As the largest lake in South America by volume and surface area, it covers around 8,300 square kilometers. The lake consists of two main subbasins connected by the Strait of Tiquina: the larger Lago Grande (also called Lago Chucuito) with depths reaching up to 284 meters, and the smaller Wiñaymarka subbasin with shallower waters. Its waters are slightly brackish and the lake is monomictic, experiencing a single seasonal circulation. The lake supports a unique ecosystem but faces environmental challenges such as pollution and receding water levels due to climate change and human impact. Lake Titicaca is culturally significant, historically linked to indigenous Aymara and Quechua peoples, and is surrounded by numerous islands, some densely populated. It is also recognized as a Ramsar wetland site, highlighting its ecological importance.
