Lake Titicaca
Titicaca (in the hispanicized spelling) or Titiqaqa (Quechua) is a large, deep lake in the Andes on the border of Peru and Bolivia. By volume of water, it is the largest lake in South America.[2][3] Lake Maracaibo has a larger surface area, though some consider it to be a large brackish bay due to its direct connection with the sea. It is often called the highest navigable lake in the world, with a surface elevation of 3,812 metres (12,507 ft).[4][5] Although this refers to navigation by large boats, it is generally considered to mean commercial craft. For many years the largest vessel afloat on the lake was the 2,200-ton, 79-metre (259 ft) SS Ollanta. Today the largest vessel is probably the similarly sized, but broader, train barge/float Manco Capac, operated by PeruRail (berthed, as of 17 June 2013, at 15°50′11″S 70°00′53″W, across the pier from the Ollanta). At least two dozen bodies of water around the world are at higher elevations, but all are much smaller and shallower.[6]
