The Waianiwaniwa River (Waireka) is a river in the Canterbury region of the South Island of New Zealand. [1]
The source is in the Wyndale Hills, which are foothills of the Southern Alps. The Waianiwaniwa River is a tributary of the Selwyn River. [1]
The Waianiwaniwa Valley originally belonged to the Deans family. This particular block belonged to one of the Deans sisters and she sold it to the Hawke family. The Hawkes broke it in turning tussock country into dairying country. The homes built by William A Hawke and Ernie Hawke still stand. The first farmer to use top dressing aircraft was Ernie Hawke on this property.
The Central Plains Water Trust previously sought approval to dam the river for their irrigation scheme, with a proposed water level of 280 metres (920 ft) above sea level. [2] The Central Plains Water Trust did not progress with these plans, and the irrigation scheme was fully completed and operational in 2017.
Māori knew it as Waireka (Sweet Water)
Irrigation is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation.

In the 1850s, European settlers named it the Cholmondeley River, but this name lapsed into disuse.

Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island.

It was formed in 1890 by the damming of the Teviot River and Dismal Swamp, with a new dam built in 1982 that raised the lake level by 5 m (16 ft). It is the site considered for a pumped-storage hydroelectricity project.

The Rangitata Diversion Race or RDR is a combined irrigation and power generation scheme that diverts water from the Rangitata River to irrigate over 100,000 hectares of farmland in Mid-Canterbury, New Zealand. The RDR project was the first major river diversion in New Zealand, and the largest irrigation scheme in the country. It was originally constructed by the Public Works Department between 1937 and 1944. The main canal is 67 km long, 10 m wide and 3 m deep.

George Arthur Emilius Ross was a New Zealand farmer and provincial politician. A cultured and well-educated man, he suffered a breakdown while at Oxford University and relocated to Christchurch for health reasons before he finished his degree. After a short period as a cadet to learn the basics of sheep farming, he became a major land owner. He was an elected member of the Canterbury Provincial Council for the rural Rakaia electorate and was on the Canterbury Provincial Executive Council on a number of occasions including nearly two years as provincial treasurer. Well-liked as an individual, he was chaotic as a businessman and went bankrupt after a harsh winter in 1867 that caused great loss of stock. He suffered a mental breakdown and disappeared from public life thereafter, with his young wife, Sibella, sustaining the family by running a school that her parents had financed for them. Ross died young aged 48 and his wife outlived him by five decades, bringing up a family of eight children by herself. The West Coast town of Ross was named after him during his lifetime.
