Some Wonderful Lakes of the World
Some Wonderful Lakes of the World
Each lake; a world of its own
Lakes are not seas; they are enclosed water bodies of substantial size; they nurture the people around giving them almost all their day today needs like food, water, transportation recreation etc. they support a bio system around its peripheries to evolve independently and develop in to an exotic culture specific to its shores. Communities living around develop a unique culture and identity. Due to these exclusivities lakeshores always offer a special charm for the visitors and act as hot tourist spots giving precious jobs to the local people.
They are all good whether big or small
There are many types of lakes like saline (The Caspian Sea), hyper saline (The Dead Sea), fresh water (Lake Victoria), high altitude (Lake Titicaca), low altitude (Dead Sea), extremely deep (Baikal), with largest island(Huron), located on lake-island (Manitou) etc. Some of them is sacred and medicinal (SpottedLake), some filled with tar and repulsive but they all have one thing in common they are all extremely useful to mankind.

This is a 100 km long lake located in the island of Sumatra that houses the largest island in a lake on an island. It has another credit as it isthe largest volcanic islandin the world. The name of the island is Pulau Samosir which was formed by the eruption of a super volcano tens of thousands of years ago. Lake Toba is formed when the caldera of the volcano got filled with water. It is believed that this explosion (occurred about 70,000 years back) was the biggest eruption occurred in the past 20 million years back.

A forty hectare lake with a depth of 75 meters; that has no water but filled with tar (asphalt) of very pure quality! It was Sir Walter Raleigh the great explorer who discovered this strange tar-lake in 1595. It is believed that some geographical phenomena would have released the underground oil deposit to above ground. When low density components evaporated the tar left there forming a lake. This ‘tar-lake has emerged as a gold mine for the government as it has become a hot tourist attraction with 20,000 annual visitors. The asphalt is mined and exported for hard cash. How long this lake would sustain such a rampant exploitation remains to be seen.

Lake Huron is second in size among the Great Lakes but it has the credit of housing world’s largest lake island (Manitoulin) that in its turn houses world’s largest fresh water lake in a fresh water lake island – the Manitau Lake. When this lake- island is 2766 sq km in area its Manitau Lake itself is 104 sq km in area; the funny thing is that Manitoulin Island houses about 107 other lakes within it. The Manitau Lake has its own islands though small making them islands in a lake within an island in a fresh water lake! This lake is drained by River Manitau.
Finnish Lakeland image courtesy: wikipedia.org
This is a territory located in the central and East Finland and as its name suggests it is a land of lakes; the total number of lakes here have never been ascertained as it is too much! It is 40 lakes per 100 sq km in this area but for Lake Inari the count is 1000 per 100 sq km! It has been guestimated that there may be 55,000 lakes altogether if all the water bodies above 200 meter wide alone are counted. Total 25% of the land areas are occupied by lakes and the rest are forests.Saimaais the largest lake that has an area of 4400 sq km. This region is locally called ‘Lampi Suomi’ meaning Finland Pond.
Nettilling Lake, Canada image courtesy: wikipedia.org
It is the largest fresh water lake on an island;located in Baffin Island, Nunavut Canada. The Baffin Island is part of the Koukdjuak plains known for the rich wild life (it supports the largest goose colony in the world). This lake gets its water from several other lakes on this island including the Amadjuak Lake which is second largest in size. The Nettilling Lake is 123 km in length and has an area of about 1956 sq km; it is 132 meters in depth; its eastern part is comparatively shallower and dotted with many islands whereas the western part is deeper and devoid of islands. The Nettilling Lake is drained by River Koukdjuak in to the Foxe Basin (a shallow basin in the Hudson Bay; named after English explorer Luke Foxe).
The Aral Sea,(a tear drop on mother earth)

Its story may be the most pathetic of all the lakes; steadily shrinking with increasing salinity; lake has shrunk exposing three deeper parts; all its fish and plants dead and with the fish; once flourished fishing industry also breathed its last; the Aral Sea at present remains as tear drop on mother earth.
It is located between Kazakhstan and Uzbekistan two members of the former Soviet Union. Initial surface area of this lake was 68,000 sq kms; it was well fed by the waters of the great rivers and endemic plants and fish were abundant. The present surface area is about 15,000 sq km! Salinity is not the only menace; pesticides, testing of biological weapons, run off of excessive chemical fertilizers, chemical effluents from factories all reduced the sea in to a dirty salt pit.
It all started with lopsided development policies of the erstwhile Soviet Union which divertedAmu Darya and Syr Darya(the rivers that fed the lake) to irrigational purposes all worked in tandem in the making of these three ugly dead seas in the Central Asia.
The Aral Sea is not an isolated case almost all the lakes in the world are under threat of faulty development agenda of the short sighted governments and in various stages of degradation. If the Aral Sea model opens anybody’s eye it would be of immense good for the generations to come.
