Which is the deepest lake?

The world’s deepest freshwater lake is Lake Baikal located in Siberia. It holds more than 20 per cent of the unfrozen fresh water on the surface of the Earth and is the oldest freshwater lake in the world – it is estimated that the lake has been here for about 20 million to 25 million years. This magnificent natural water body is known as the ‘Galapagos of Russia.’ Its age and isolation have led to the existence of some of the most unusual and exceptional freshwater fauna of the world, making it a hotspot for evolutionary science.

Baikal is home to a great variety of animal and plant species that cannot be found anywhere else on the planet. Of the rare species here, the Baikal seal (also called the nerpa) is the only species of seal in the world to exist in a freshwater habitat. Since the lake lies hundreds of kilometres inland, it remains a mystery as to how the ancestors of these seals arrived in Lake Baikal. More than 330 rivers and streams enter Lake Baikal- the largest of which include the Selenga, Barguzin, Upper Angara, Chikoy, and Uda. There are a number of industries along the shores of Baikal. Mining (mica and marble), cellulose and paper manufacturing, ship building, fisheries, and timber are some of the prominent ones.

Which river flows into neighbouring Tamil Nadu before draining into the sea at Poompuhar?

Cauvery water enters Tamil Nadu from Karnataka at Dabhakuzhi near Biligundulu in Dharmapuri district and the river endures rampant pollution from Mettur till the time it enters the sea in Poompuhar.

Cauvery is pumped from a place 100 km away from Bengaluru, making it Asia’s costliest water. The city receives about 1,390 million litres per day (MLD) water, and sewage of an equal amount or more is generated. The Bangalore Water Supply and Sewerage Board has 24 sewage treatment plants capable of treating only about 760 MLD. Remaining sewage flows directly into the lakes.

auvery’s tributaries, Noyyal and Bhavani, carry a considerable amount of pollution. The Noyyal is as good as dead due to effluents released by more than 700 dyeing units in Tiruppur. From Karur to Tiruchirapalli, the river flows at its broadest and is called Akanda Cauvery. Here, the river is put to severe stress due to rampant sand mining, which goes unabated till date despite numerous strictures by the Madras High Court.

Though the polluted water undergoes some natural cleaning process by the time it reaches the Delta region, letting of sewage and dumping of garbage and hospital waste into the river pollute it further, making the water unfit for drinking and sometimes even for irrigation.

Activists allege that the industries in the Cauvery belt release untreated effluents into the river during the night to escape the wrath of local people. The paper mill owned by the Tamil Nadu government near Karur is also a major cause for 
water pollution in the area and activists allege the factories on the banks of the river consume more water than they are allowed to pump.

From which country does the Himalayan River Manas flow into India?

The river flows through Bhutan in a south-west direction between two ranges of the Lower Himalayas in V-shaped gorges and enters into Assam in India into the south-central foot hills of the Himalayas.

The river valley has two major reserve forest areas, namely the Royal Manas National Park (43,854 hectares (108,370 acres), established in 1966) in Bhutan and the contiguous Manas Wildlife Sanctuary (391,000 hectares (970,000 acres) in 1955 increased to 95,000 hectares (230,000 acres) in December 1985) encompassing Project Tiger reserve, an elephant reserve and a biosphere reserve, which constitutes a UNESCO World Heritage Site declared in December 1985.

The Manas River drains 41,350 square kilometres (15,970 sq mi) of eastern Bhutan and northeast India. It has three major branches: the Drangme Chhu, Mangde Chhu, and Bumthang Chhu that cover most of eastern Bhutan, with the Tongsa and Bumthang valleys also forming part of its catchment. The area drained in Bhutan territory is 18,300 km2 and is bound by the geographical coordinates 26.217°N 90.633°E. A part of the main stem of the river rises in the southern Tibet before entering into India at Bumla pass at the northwestern corner of Arunachal Pradesh.

Out of the large catchment of the river valley, protected or reserved areas have been specifically demarcated, both in Bhutan and India, which are declared national parks or sanctuaries. The two reserved forest and wild life areas cover an area of 9,938.54 square kilometres (3,837.29 sq mi), which account for about 24% of the total catchment area of 41,350 square kilometres (15,970 sq mi) of the Manas river valley; brief details are provided.

Which river is largely referred to as Tsangpo throughout its upper case?

The Brahmaputra called Yarlung Tsangpo in Tibet, Siang/Dihang River, in Arunachal Pradesh and Luit, Dilao in Assam, is a trans-boundary river which flows through Tibet, India and Bangladesh. It is the ninth largest river in the world by discharge, and the 15th longest.

The BrahmaputraRiver originates in the Chemayungdung mountain ranges which nearly sixty miles south-east of Mansarovar lake in the MountKailash range in Southern Tibet at an elevation of 5300 m.A spring called Tamchok Khambab spills from the glaciers which later gather breath and volume to become the Tsangpo, the highest river in world.

Apart from the name Tsangpo, the Brahmaputra is also known by its Chinese name, Yarlung Zangbo in Tibet.  There are several tributaries of Tsangpo in Tibet. Before entering India, the river passes Pi (Pe) in Tibet and suddenly turns to the north and northeast and cuts a course through a succession of great narrow gorges between the mountain Gyala Peri and Namjabarwa (Namcha Barwa) in a series of rapids and cascades.

In India the total basin area of BrahmaputraRiver is 197 316 sq. km. which 5.9% of the total geographic area of the country. In India the river is spread over states of Arunachal Pradesh, Assam, West Bengal, Meghalaya, Nagaland and Sikkim.
