Phoksundo Lake (Nepali: फोक्सुण्डो, romanized: Phoksuṇḍo, pronounced [pʰoksuɳɖo]) is an alpine fresh water oligotrophic lake in Nepal's Shey Phoksundo National Park, located at an elevation of 3,611.5 m (11,849 ft) 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).[2] In 2004, a survey by the Department of Hydrology and Meteorology measured the maximum depth of the lake at 145 m (476 ft).[3] In 2019, another detailed survey was carried out by the Department of Hydrology and Meteorology, which measured the maximum depth of the lake at 136.20 m (446.9 ft).[4]
In September 2007, Phoksundo Lake has been designated a Ramsar site.[5]
On the lake' southern end, the village of Ringmo sits on the 30,000- to 40,000-year-old landslide dam that formed the lake.[6] Past the dam, the waters of the lake plunge over a 167 m (548 ft) tall waterfall.
