In Nagartse County in Shannan Prefecture, the lake is 4,400 meters above sea level. It covers an area of 800 square kilometers and is 30-40 meters deep. Yamdrok means upper pasture and Yum means green jade in Tibetan. In a bird's-eye view, the lake is like a big piece of sapphire inlaid in the mountains and is very beautiful.
The lake is rich in hydropower resource. Its surface is more than 800 meters higher than the Yalutsanpo River at the foot of the mountain. Also here stands the Yamdrok Power Station well known for its high elevation in the world. To its south stands the magnificent Samding Monastery where Dorje Pamo, the only woman Living Buddha in Tibet, stayed and presided.
