Koombooloomba Hydro

Koombooloomba Hydro is a dam release point hydro situated on Koombooloomba Dam. The hydro operates by capturing energy from existing water releases required for the operation of Kareeya Hydro.

The hydro was commissioned in 1999, and was developed in line with principles of environmentally sustainable development. Its location on Koombooloomba Dam utilised the infrastructure established when the dam was constructed in 1960. The original dam design incorporated an outlet for use by future hydro-electric development.
