The largest lake of Madagascar

Located off the Eastern coast of Africa bordering the Indian ocean island of Madagascar has amazing endemic flora and fauna. They are full of variety of flora and fauna which is nowhere else in the world can not be found. Most of the animals and plants present on the island, inscribed on the pages of the red Book. Many interesting animals can be seen on the territory of the largest lake of Madagascar called the Alaotra. What is more interesting is the largest lake in Madagascar?

The location and size of the lake

The largest lake of Madagascar Alaotra

Alaotra is a lake in the North-Eastern part of the island, in the province of Toamasina. From the waters of the lake begins its course the river Maningory. Alaotra area is 900 square kilometres. The average depth of lake is about 0.6 meters, and the deepest point of lake is at a distance of 1.5 meters from the surface. Lake water Alaotra serve for drinking, to irrigate rice fields and catching this species of fish.

Problems of lake

Marshland around lake Alaotra

Currently, there is a tendency to shallowing of the lake, and, consequently, to reduce its size. This is due to the fact that it is surrounded by fertile plains, on which local residents grow rice. This was cut forests that once flanked the lake, which caused the sliding of soil into the lake and siltation. Now the area and depth Alaotra decreases. And this region has almost lost its former importance of the rice granaries, and local authorities increasingly have to buy rice in other countries.

Unique animals can be found in the lake district

Around the lake Alaotra located marshy areas where researchers have discovered a rare species of animals, which weigh a little more than 500 grams. Called such animals mongooses Durrell (in honor of English zoologist).

Mongoose Durrell

These animals have a greater similarity with mongoose, but most belong to the family of Madagascan predators. Just look at the face of the animal – he looks very unfriendly, and he shows all his views that it is better not to touch it. For the first time scientists have found these little wild animals around here in 2004, but then only managed to take a picture of the animal. In 2005, mongoose Durrell managed to catch – so, after some study it was discovered a new species of bat living in the lake Alaotra.

Now predatory animals are on the verge of extinction. After all, they were detected only in two individuals. And since they are found only on the shores of the lake, and this area has long threatened the reproduction of the rice fields, cutting down the remnants of trees, it can lead to ultimate destruction of rare species of animals, plants and even fish.


Except mongoose Durrell in the area Uluorta is found another species, which also soon may disappear, and therefore inscribed on the pages of the red Book, is hapalemur. Just the nature of hapalemur there are approximately 2,500 individuals. Today, these lemurs are trying to breed at the local zoo and in the wild they only live near the lake. Because it is the only place on the island where grows a large quantity of reeds, which hapalemur happy to regale. But the reed beds are regularly destroyed by local residents for the arrangement of agricultural land for rice cultivation.

Therefore, the threat hung over the lake Alaotra because it disappears, and on most of the rare animals that live in this part of the island of Madagascar. It is possible that soon it will be possible to call this lake the largest on the island – the islanders in their present relation to this site may remain some memories of the existence of lakes and wetlands.
