Y- shaped lakes in the lap of mountains
Phoksundo Lake, is an alpine fresh water Oligotropic lake in Nepal's Shey-phoksundo National Park, located at an elevation of 3,611.5 m (11,849 ft) above sea level in the Dolpa district. Phoksundo Lake is 494 ha (1.91 sq mi) in size with a water volume of 409,000,000 m3 (1.44×1010 cu ft) and a discharge of 3.715 m3/s (131.2 cu ft/s). In 2004, a survey by the Department of Hydrology and Meteorology measured the maximum depth of the lake at 145 m (476 ft).
In September 2007, Phoksundo Lake has been designated a Ramsar site.
On the lake' southern end, the village of Rigmo sits on the 30,000- to 40,000-year-old Landslide damp that formed the lake. Past the dam, the waters of the lake plunge over a 167 m (548 ft) tall waterfall.
There are more than 20 Stupas in the southern belt, and one Gompa in the eastern side of the lake, where annual prayers and worship are carried out. Traditional Tibetan culture prevails in upper Dolpo; Buddhism and Bon are prevalent in lower Dolpo, including Ringmo village.
