Yellow River Basin has a wide extension of area. The river begins in the Maqu Quguo located at the north of Bayankela Mountain on the Xizang - Qinghai Plateau. In the source region many clear branches form into one wandering stream and then pools into the largest two "Sister Lakes" Zhaling Lake and Eling Lake.
