Siang River, which has been lifeline of Arunachal Pradesh for so long has suddenly turned muddy at various places. The river water, which is always clean and clear during winters, is now full of thick black mud and dead fish this winter.
The authorities of East Siang district have declared that the water of this river is no longer appropriate for consumption. Deputy commissioner Tamyo Tatak has said, “The water can’t be used for any purpose because it contains a cement-like thick material. A lot of fish died one-and-half months ago.”
He added further, “In the last monsoon season, the river turned dark and we thought that it was because of mud being carried by the river. The rainy season is long over but the river water is still black. From November to February, the water is crystal clear and pure. Even my grandfather has never seen or heard of such a thing happening to the waters of the Siang.”
People and politicians in Arunchal Pradesh, especially those living in Pasighat in East Siang district, think that the China’s river diversion plan is the reason behind this contamination. It is speculated that China has a plan to dig a 1000-km tunnelto divert the Yarlung Tsangpo River from Tibet to Taklimakan Desert in Xinjiang.
Siang River originates in China and then enters India through Arunachal Pradesh. In Assam two rivers, Dibang and Lohit join Siang and then it is known as the Brahmaputra. Probably,river is carrying cement and mortar from that river diversion construction from China to India and polluting crystal clear water.
