The Riñihue Lake (Spanish: Lago Riñihue, Spanish pronunciation: [riˈɲiwe] Pronounced: /rinˈjiːwɛ/ REEN-yee-WE) is a lake of glacial origin in eastern Valdivia Province, southern Chile. It is surrounded by several mountains. The eastern side receives the waters of the Panguipulli Lake by the Enco River, its main contributor. It is the last of the Seven Lakes chain. In the west it is cut into two arms by the Tralcán Mount, and on the east side lies the Mocho-Choshuenco volcano. In the south the lake is bounded by the Cerros de Quimán mountains.
