Songhua River

From Free net encyclopedia

Image:LocationSonghua.PNG The Songhua River (Template:Zh-cp) is a river in Northeast China, and is the largest tributary of the Heilong River (Amur), flowing about 1,927 km from Changbai Mountains through the Heilongjiang and Jilin provinces. The river drains 212,000 square miles of land. It joins the Amur at the town of Dongjiang. The river has a dam at Fengman, which is used for hydroelectricity production. It forms a lake that stretches 62 km upstream. Below the dam, the river flows northwest until its largest tributary, the Nen River, joins it near Da'an. The Nen River drains the northern Manchurian Plain. The river travels east until it joins the Hulan River near Harbin. Then it passes between the northern end of the eastern Manchurian mountain system and the Lesser Khingan Range. The river then flows into the Amur River valley. The river freezes from late November until March. It has its highest flows when the mountain snow melts during the spring thaw. The river is navigable up to Harbin by medium-sized ships. Smaller craft can navigate the Songhua up to Jilin and the Nen River up to Qiqihar. In November 2005, the river was contaminated with benzene, leading to a shutdown of Harbin's water supply and threats of a Russian lawsuit against China.
