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