Opuha Dam

The Opuha Dam is located on the Opuha River, a tributary of the Opihi River in South Canterbury, New Zealand. The dam is used for water storage for farming irrigation and provides 7.7 MW of electricity to New Zealand's national grid. The site has been identified as an Important Bird Area by BirdLife International because it supports breeding colonies of the endangered black-billed gull.[1]

History

The dam failed during construction on 6 February 1997 due to heavy rain.[2] It was completed in 1998, creating Lake Opuha.[3]
