In the downstream, it receives the smelting water on south slope of Kunlun Mountain and some underground water, the flow amount obviously increase. The Qumar River flows toward east after Fayuan. It passes through Yelusu Lake and Qinghai-Tibet Highway, and then turn to south at last. At the point about 200 kilometers to the estuary of Dam River, it flows into the Tongtian River.
