Gannan Tibetan Autonomous Prefecture
Tao River () is a right tributary of China's Yellow River. It starts in Xiqing Mountains () near the Gansu–Qinghai border, flows eastward across Gannan Tibetan Autonomous Prefecture, and then northward more or less along the border between Dingxi Prefecture-level City in the east and Gannan and Linxia Prefectures in the west. It flows into the Yellow River (actually, the Liujiaxia Reservoir) near Liujiaxia Town (the county seat of Yongjing County), just upstream of Liujiaxia Dam.
