Lake Pelku

Lake Pelku, Pelkhu, or Paiku
is a lake at elevation on the Tibetan Plateau in Shigatse Prefecture. It is south of the Yarlung Tsangpo River, bordering Saga County, Gyirong County, and Nyalam County.
The lake is long and wide at its narrowest. It is surrounded by mountains reaching. Streams fed by glaciers cascade to the valley floor, but most sink into alluvial deposits before reaching the lake.
The surrounding catchment is an endorheic basin with no outlet. It would overflow into the Yarlung Tsangpo with a water level about higher. The lake's brackish water is evidence that it has not overflowed in hundreds, if not thousands, of years.
