Namtso lies in both Damxung County, within Lhasa, and Baingoin County, within Nagqu. An administrative line divides the surrounding territory, but the lake is a continuous body of water. That distinction matters when naming a photograph or telling a story about a particular shore.
The lake occupies the high Tibetan Plateau, where open water, grassland and distant mountains enter the same view. A shoreline photograph gives one relationship between them; a wider map reveals how much of the lake remains beyond the frame. The familiar name belongs to more than a single viewpoint or visitor area.
