Benmore Dam is a large earthfill dam located on the Waitaki River in the South Island of New Zealand. Completed in 1965, it is one of the largest dams in the country, primarily used for hydroelectric power generation and irrigation. The dam creates the Benmore Reservoir, which is a popular spot for recreational activities such as fishing, boating, and water sports. The facility plays a crucial role in New Zealand's energy supply, contributing significantly to the national grid through its hydroelectric power station.
