Benmore dam is the largest dam in the Waitaki power scheme in New Zealand's South Island. With a generating capacity of 540 MW, Benmore Power Station is the second largest hydro station in New Zealand.

The dam is the largest earth-filled water-retaining structure in New Zealand. Its core is impermeable clay-like gravel, supported by two massive shoulders of river gravel. Lake Benmore has a volume of 12.5 million cubic metres which is about 1.5 times as much water as Wellington harbour.

The construction of the dam and hydro-electric station began in 1958 and it was commissioned in 1965.

Hugh MacDonald's three-screen spectacle, "This is New Zealand," screened at Expo '70 in Osaka featured the Karelia Suite by Sibelius.

  • I used to think that the Benmore dam was big until I watched a doco on the three gorges dam in china which generates 22500 MW which is hard to comprehend
