Arunachal Pradesh’s Siang River is Turning Black & Poisonous, China’s Mischief Suspected


For centuries, the River Siang of Northern Arunachal Pradesh is termed as the lifeline of the population. But, it seems that it won’t be called for longer times. The crystal clear water of river Siang has turned black and is alarming a panic situation for the state.

The district authorities of Siang triggered the alarm and East Siang district deputy commissioner Tamyo Tatak said, “The water can’t bring used for any purpose because it contains a cement-like thick material. A lot of fish died one-and-half months ago.”

The deputy commissioner said 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.”

The deputy commissioner suspects the China for the contamination of water and already the water samples have been collected by Central Water Commission. The deputy commissioner Tatak also stated, “It seems that some major cement work is on in the upper reaches of the river in China may be China is carrying out some deep water boring work. What else could be the reason for such a big river, which becomes the Brahmaputra, remaining black in color for nearly two months.”

The Brahmaputra’s principal constituent river is the Siang river which flows for 1,600 km through southern Tibet with the name the Yarlung Tsangpo or Yarlung Zangbo before reaching India.

In India, Siang is also called Dihang which after flowing for 230 kilometer joins the Lohit. After, 35 kilometers downstream of Pasighat in East Siang, the Dibang river joined it. The deputy commissioner added that an independent report describing the alarming situation of Siang river has been submitted to the government of Arunachal Pradesh.

The triggering situation of Siang river’s water turning black would be worst by the China’s plan of digging a 1000 kilometer tunnel in the Brahmaputra. China wants to divert world’s longest river water Yarlung Tsangpo river from Tibet to Taklimakan Desert in Xinjiang.

On the contrary, China has denied the allegations of giving the reason to turn the water of river Siang black.
