The Waitaki Dam is one of eight hydroelectric power stations which form the Waitaki hydroelectric scheme on the Waitaki River in the Canterbury Region of New Zealand. The dam was the first of three to be built on the Waitaki River and was constructed without earthmoving machinery; over half a million cubic metres of material was excavated, almost entirely by pick-and-shovel. [2]
The lake is created by the Waitaki Dam, a 36m high concrete gravity dam built between 1928 and 1934. Waitaki Dam was the first hydroelerctic dam built on the Waitaki river. The Waitaki power station has a total installed capacity of 105MW. Waitaki was the last dam built in New Zealand with excavation done with pick and shovel, not heavy ...
The Waitaki Hydro Scheme, which includes several large dams, is one of the largest hydroelectric projects in the nation. The Waitaki dam was built first, between 1928 and 1934, and without earth-moving machinery, followed by the development of the Aviemore Dam which created Lake Aviemore , and then Benmore Dam which created Lake Benmore .
In the 1950s development of the Clutha River with Roxburgh Dam and the upper Waitaki in the MacKenzie Basin with "Tekapo A" was begun. With commissioning of the HVDC Inter-Island link in 1965, the Waitaki scheme was further expanded with Benmore Power Station (1965), Aviemore Dam (1968), and later Tekapo B, and Ōhau A, B and C.
Benmore (540 MW) (2,200 GWh) 1965. Aviemore (220 MW) (940 GWh) 1968. Waitaki (105 MW) (500 GWh) 1935. Project Aqua was a proposed scheme of six dams on a man made canal running from the Waitaki Dam to the sea. It was cancelled by Meridian Energy on 29 March 2004.
The lake is the reservoir of Benmore Dam, New Zealand's largest earth dam, [5] which was created as part of the Waitaki hydroelectricity power scheme. Construction of Benmore Dam was approved in 1957 [6] and the lake was filled in December 1964. [5] After the lake was created the incidence of seismic shocks increased by a factor of three to six ...
Annual generation. 2,215 GWh (7,970 TJ) Benmore Dam is the largest dam within the Waitaki power scheme, located in the Canterbury Region of New Zealand's South Island. There are eight other power stations in the Waitaki Power Scheme. The dam is the largest earth-fill (zoned embankment dam) water-retaining structure in New Zealand.
