Option 2 : Lake Faguibine

The correct answer is Lake Faguibine.

  • Lake Faguibine
    • It is an isolated lake in Mali, west of Timbuktu (Tombouctou).
    • It lies north of the Niger River in the Macina depression, and it is reached by branches of Niger in times of flood.
    • At high water, it reaches a length of about 50 miles (80 km).
    • One example of increasing aridity in Mali appears in Lake Faguibine.
    • These false-colour Landsat satellite images of the lake show how it changed over the decades.
    • Lake Faguibine has experienced widely fluctuating water levels since the turn of the twentieth century but, at its fullest, has ranked among the largest lakes in West Africa.
    • In 1974, this lake covered roughly 590 square kilometres (230 square miles).
    • Starting in the late 1980s, a drop in precipitation steadily dried the lake.
    • By the late 1990s, the traditional livelihoods of fishing, agriculture, and livestock herding became impractical. Even though normal rainfall resumed after the year 2000, the lake remained nearly dry. Hence, Option 2 is correct.

  • Lake Victoria
    • It is located at the border of Uganda, Kenya, and Tanzania on the African continent.
    • River Nile originates from Lake Victoria and drains into the Mediterranean sea.
    • Victoria Lake is the largest tropical lake in the world and one of the largest freshwater lakes in the world by area.
    • Its area is 26,828 square miles (69,484 square km).
    • Among the freshwater lakes of the world, it is only behind the Lake Superior of North America.
    • Its waters fill a shallow depression in the centre of the great plateau that stretches between the Western and Eastern Rift Valleys.
  • Oguta Lake
    • It is a lean 'finger lake' formed by the damming of the lower Njaba River with alluvium.
    • It is the largest natural lake in Imo State, Southeastern Nigeria; within the equatorial rainforest region of Niger Delta. 
  • Lake Volta
    • It is the largest artificial reservoir in the world based on the surface area, is contained behind the Akosombo Dam which generates a substantial amount of Ghana's electricity.
    • It is completely within the country of Ghana and has a surface area of 8,502 square kilometres.
