As the silver waters of the Kishanganga rush through this north Kashmir valley, Indian labourers are hard at work on a hydropower project that will dam the river just before it flows across one of the world's most militarised borders into Pakistan.
The loud hum of excavators echoes through the pine-covered valley, clearing masses of soil and boulders.
The 330-MW dam shows India's growing focus on hydropower but also highlights how water is a growing source of tension with downstream Pakistan, which depends on the snow-fed Himalayan rivers for everything from drinking water to agriculture.
Islamabad has complained to an international court that the dam in the Gurez valley, one of dozens planned by India, will affect river flows and is illegal. The court has halted any permanent work on the river for the moment, although India can still continue tunneling and other associated projects.
In the years since their partition from British India in 1947, land disputes have led the two nuclear-armed neighbours to two of their three wars. The next flashpoint could well be water.
