Question

Which lake is the highest navigable lake in the world?
A- Lake Victoria
B- Lake Superior
C- Lake Baikal
D- Lake Titicaca

Answer 1

Hint
It is a freshwater lake on the border of Bolivia and Peru in the Andes and is South America's largest lake. The lake is situated high in the Andes on the border of Peru and Bolivia, at the northern end of the Endorheic Altiplano basin. The western half of the lake is situated in the Peruvian Province of Puno, and the eastern side is located in the Department of La Paz in Bolivia.

Complete answer:
The surface elevation of Lake Titicaca is 3,812 m (12,507 ft). In general, the "highest navigable lake" argument is deemed to apply to commercial craft.

The level of Titicaca fluctuates seasonally and over a period of years. The level of the lake increases during the rainy season (summer, from December to March) and usually falls during the dry winter months. Titicaca was historically thought to dry up slowly, but modern studies have seemed to contradict this, suggesting a more or less frequent cycle of rising and fall.

Lake Titicaca feeds into five main river systems. These are Ramis, Coata, Ilave, Huancané, and Sanchez, in terms of their relative flow volumes. In Titicaca, more than 20 other smaller streams are empty. There are 41 islands in the lake, of which several are heavily populated.
The fish life of Lake Titicaca consists primarily of two killifish species (Orestias)-a small fish, normally striped or barred with black, and a catfish (Trichomycterus). In 1939, and subsequently, the Titicaca trout were introduced. The shallower regions of the lake are populated by a large frog (Telmatobius), which can reach a length of almost afoot.

Therefore the correct answer is D

Note
Elevation of Lake Victoria is 1,135 m
Elevation of Lake Superior is 183 m
Elevation of Lake Baikal is 456 m
