Ongi River
{{Short description|River in west-central Mongolia}}
The Ongi River ({{langx|mn|Онги гол}}, {{lang-zh|翁金河, 翁金高勒}}) flows from the southeastern slopes of the Khangai Mountains in Övörkhangai Province for {{convert|435|km|mi|-1|disp=or}} through the endorheic Ongi River Basin in Mongolia and through the aimag capital Arvaikheer. In some particularly wet years, it used to empty into Ulaan Lake in north central Ömnögovi Province, in most years it dries up earlier.
In recent years it has been additionally threatened by 37 mining operations within the basin, but successful pressure by Tsetsgeegiin Mönkhbayar and the Ongi River Basin Movement helped convince 35 of the operations to cease explorations and harmful activities in the region.April 23, 2007. ‘Earth Day in Mongolia: Onggi River Movement Receives Award’, [http://www.mongolia-web.com/content/view/967/2/ Mongolia-Web.com] The water and groundwater in this area may be contaminated with mercury and cyanide from the mining industry.Lovgren S. 2008. ‘Mongolia gold rush destroying rivers, nomadic lives.
