Ganghes River – Vernasi, India

Rising in the Himalayas and emptying into the Bay of Bengal, the Ganghes river drains one-fourth of the territory of India, and its basin supports hundreds of millions of people. From time immemorial it has been the holy river of Hinduism. 

The Ganges basin encompasses some 419,300 square miles (1,086,000 square km) and contains the largest river system on the subcontinent. The water supply depends partly on the rains brought by the southwesterly monsoon winds from July to October as well as on the flow from melting Himalayan snows in the hot season from April to June.

The religious importance of the Ganges may exceed that of any other river in the world. It has been revered from the earliest times and today is regarded as the holiest of rivers by Hindus.
