What are major lakes of Madagascar?

Answer 1

Major west coast rivers include: the Mananara and Mangoro rivers (which flow from the central highlands to the east coast into the Indian ocean) and the Maningory River (which flows from the Lake Alaotra to the east coast and the ocean).

On the west coast, the rivers are longer and run more slowly because the slope of the land is less steep. Major west coast rivers include: the Betsiboka (the longest river of Madagascar - the port of Mahajanga is located at the mouth of this river), the Sambirano, the Mahajamba, the Mania, the North and South Mahavavy, the Mangoky, and the Onilahy. In the south, there is the often-dry Mandrare River.

Major Lakes: The biggest lake in Madagascar is Lake Alaotra; it is approximately 40 km long.
