Tsarap River

[3] Then the Tsarap River flows down the main Zanskar valley, through the towns of Mone, Tichip, Jamyang Lang, Dorzong and Chia.

[4] The Tsarap River contributes to the minimal agricultural production of the Zanskar valley, mainly to the lower areas of Chia, by providing irrigation to the fields of barley, wheat, buckwheat and peas.

[6] A lake was formed on the Tsarap River due to a landslide dam at 33°17′25″N 77°17′06″E / 33.29028°N 77.28500°E / 33.29028; 77.28500, 90 miles (140 km) upstream (south) of Padum, the commercial hub of Zanskar.

The landslide, which occurred on 31 December 2014 between Shun and Phuktal villages, was first noticed when the Alchi Hydroelectric Power Project downriver reported a drop in water level.

A report submitted by local authorities prohibited the use of explosives to clear the debris, for fear that it would trigger more landslides and aggravate the situation.

The committee, headed by the Union Cabinet Secretary, deployed a team at the site to carry out controlled blasting and manual work to allow channelized flow of water.
