The Golmud flows north from the Kunlun Mountains, past Golmud, to a wide alluvial fan along the central part of the south side of the Qarhan Playa. For most of the year, only a small stream reaches Dabusun Lake but meltwater from the mountain glaciers sometimes floods into the other channels, spreading from West Dabusun Lake in the west, along the entire southern shore of Dabusun in the middle, and to Tuanjie Lake in the east.
