Kameng River


    In News 

    • The Kameng river is changing colour which has turned black and muddy.


    • It is a major tributary of the Brahmaputra river in Arunachal Pradesh’s East Kameng district.
    • Called Jia Bhorelli in Assam.
    • It is a lifeline for many and has its source in a glacial lake near the Nyegi Kangsang, one of the highest mountains in Arunachal Pradesh.
    • Concerns
      • It continues to remain black, muddy and unsuitable for use.
      • The water was reporting a high level of turbidity (suspended particulates in a liquid) leading to the change in colour.
      • This depletion in oxygen levels had led to the death of thousands of fish.
    • Reasons: 
      • Some sort of a landslide/avalanche in the upper reaches of the river.
      • There was intense erosion along the Warriyang Bung — a tributary of the river upstream in the Khenewa Circle — which had led to the deposition of mud, debris, boulders and trees that the river carried downstream.
