Two major tributaries of the river, the Hun He ("muddy river") and the Taizi He, both of which flow down from the Qianshan range, used to flow into the Liao River shortly before it flowed into the sea, but the Atlas of China (Beijing, SinoMaps Press, 2006) shows that while the two tributaries continue to follow their traditional route and flow into the sea at what this atlas still identifies as the "Liao He Kou", the mouth of the Liao River, virtually all of the water of the Liao He has been diverted into the ShuangTaizi He, which flows into Bohai Gulf about to the northwest.
