Lonquén River

Lonquén River in the Nuble Province of the Bío Bío Region of Chile. It forms at the confluence of the esteros Pichimávida and Colomávida that originate in the mountains in the east of the province. Its course lies from north to south, receiving from the west the flow of the esteros of La Huerta, Coipuencillo, El Salto, Coroney and Ninhue, and from the east tributaries, estero Torrecilla, and other lesser tributaries like the estero Tiuque. The Lonquén river then changes direction moving from east to west. In this section it receives from the north the tributaries of the esteros Ranquil, Cholchol, Reloca, San Jose and Santa Rosa and from the south the estero Corontas, Buenos Aires, Luengos, Cabrería, Molino and Antequereo. It then empties into the Itata River from its northern bank as the Itata is turning toward the west.

Fort Lonquén was built in 1602 by the Governor Alonso de Ribera on the south bank of the Lonquén River nine kilometers above its confluence with the Itata River.
