With the Red River turning a surprisingly clear blue-green shade in its upstream sections, the absence of its usual muddy, pinkish color is being blamed on dams and polluting factories.

For a week now, the Red River section that flows through Lao Cai Province has become so clear that there are some shallow areas towards the banks where the river bed can be seen at a depth of one meter. While this looks like a welcome development, experts say this is happening because of withheld alluvium and pollution caused by factories on the river banks.
