Bueno River

Bueno River (Spanish: Río Bueno) is a river in southern Chile. It originates in Ranco Lake and like most of Chile rivers it drains into the Pacific Ocean at the southern boundary of the Valdivian Coastal Reserve. Its lower flow forms the border between Osorno Province and Ranco Province. Traditionally it marks also the northern boundary of the indigenous Huilliche territory known as Futahuillimapu.[2] The river passes through Río Bueno commune and city that takes name from the river.

The major tributaries of the Bueno River are the Pilmaiquén River and the Rahue River, joining the river from the south. The former is the outlet of Puyehue Lake and the latter is the outlet of Rupanco Lake.

Starting upstream the following settlements lie along the river: Puerto Nuevo at the source, Río Bueno, Trumao, Llancacura, and La Barra at the outflow in the ocean.

The original Huilliche name for the river was Huenuleufu, a combination of huenu "upper" and leufü "river". Río Bueno is thus a hybrid word with huenu being replaced by phono-semantic matching with the Spanish word bueno "good".[3]

In 1654 Bueno River was the site of the battle of Río Bueno between a Spanish slave-hunting expedition and local Mapuche-Huilliches.[4] This battle ended in clear defeat for the Spanish forces whose pontoon bridge broke apart causing many casualties.[4]
