Yamdrok Lake is one of the three largest sacred lakes in Tibet. It is over 72 km (45 miles) long. The lake is surrounded by many snow-capped mountains and is fed by numerous small streams. The lake does have an outlet stream at its far western end.
Around 90 km to the west of the lake lies the Tibetan town of Gyantse and Lhasa is a hundred km to the northwest. According to local mythology, Yamdok Yumtso lake is the transformation of a goddess.
Yamdrok Lake, also known as Yamḍok Yumtso, has a power station that was completed and dedicated in 1996 near the small village of Pai-Ti at the lake’s western end. This power station is the largest in Tibet.
