Bio Bio River

This river is 2nd largest, and widest river in Chile. It flows for 240 miles until it reaches the Gulf of Arauco, located in the Pacific Ocean. It originates from two lakes located in the Andes Mountains, the Icalma and the Galletue. Over 1,000,000 people use the river for drinking, irrigation, and recreation.

The river served as a barrier between the Mapuche Indians in the South, and the Spanish Chileans in the north. It existed as a barrier until the late 1800’s.

The Bio Bio was considered the best whitewater rafting venue in the world in the 1980’s, but the construction of a dam caused the river to flow differently (Bio Bio River Case, Chile).
