The Cupaño, better known as the Trongol River, is a river in Chile, located approximately three kilometers from the center of Los Álamos. After its confluence with the Curanilahue River, they are called the Lebu River until they flow into the sea in the city of the same name. [1]
Course
It has a length of between 17 and 30 kilometers from the Cupaño Valley to its mouth on the shores of Lebu, when it reaches the Lebu sector, this river is called the Lebu River. Its tributary is the Los Pinos River.
In the widest sector (Lebu) it measures approximately 250 m, and in Los Álamos (bridge sector) about 50 m.
Population, economy, and ecology
The Cupaño River has a wooden suspension bridge measuring approximately 80 m in length and 4 m in width, one of the main attractions in the Los Álamos area.
History
Its involvement in Chilean history begins in the with the conquistador Pedro de Valdivia who crossed the river in his race towards Fort Tucapel where he would be assassinated by Lautaro.
Francisco Solano Asta-Buruaga y Cienfuegos wrote in 1899 in his posthumous work Diccionario Geográfico de la República de Chile about the area:
- Cupaño.-—Estate in the department of Cañete, located on the south side of the Lebu River in a northerly direction from the capital city. Facing the estate, the river has the Cupaño ford, which crosses the road from Arauco to that city and which is five or six kilometers upstream from the Gualgalén spot. Some change the name to Copañu. In a spot on the south side of the ford, on June 2, 1817, the governor of the Arauco plaza, Don José Cienfuegos, and his entourage were killed, invited there for a peaceful meeting by a few chiefs from the surrounding area, at the suggestion of the royalist leader Sánchez, ambushed in the vicinity, and who suddenly fell with a strong force on that governor; see city of Nacimiento.[ citation needed]
