Going Under for the Good of the Nation
|
This country’s previous leaders didn’t bother much with community consultation or environmental impact assessments back in the 1980’s.
From 1968 onward the series of announcements that led to the eventual creation of Lake Dunstan, left residents of Cromwell and surrounding rural areas awash with shock and heartbreak. Over 2000ha including farmland, 17 orchards, homes and even the main streets were set to go under. We want the next chapter in the history of Lake Dunstan to reflect a period of upping our game and getting it right for the community and the environment. |
Lagarosiphon
|
Lagarosiphon was first recorded in the Hutt Valley in 1950 but can now be found all over NZ. 500ha of the lake bed (1/5th of total lake) is suitable for Lagarosiphon and is already saturated; 139ha of that is used for recreation.
In recent years we have seen a decline in water-orientated activities due to the increasing safety risk of weeds entangling around feet, propellers and possessions. Recreation is incredibly important to the mental and physical well being of the local communities which continue to suffer as weeds saturate the lake. |
Silt/Sediment
|
The Shotover river (which feeds into the Kawarau) carries between 1.6 and 2 million m³ of silt annually. Before the dam, the sediment would be carried down the Clutha river out to the pacific ocean 75km south west of Dunedin.
Now deposited in the Lake Dunstan and Kawarau arm, silt has formed islands and shifted the shoreline. Numerous locations are no longer viable for swimming, fishing or boats as they are too shallow, inaccessible or dangerous. |
Water Quality
|
In 2020, Cromwell’s population was over 7,000 and is predicted to reach over 15,000 by 2050. As Cromwell continues to grow, there is a risk of contamination of drinking water if quality deteriorates as Lake Dunstan and the Kawarau Arm.
The 2018 CODC 10 year management plan states that Cromwell's water supply does not have protozoa and virus protection meaning it doesn't meet the New Zealand Drinking Water Standards. |
Air Quality
|
In July 2021, Cromwell was named as one of the worse towns in Otago for air pollution. Air pollution can impact the health of humans in a variety of ways with the elderly, young people and vulnerable groups most at risk of the negative impacts. Common health effects including irritation of the eyes, throat and lungs, cancer & premature deaths.
Good air quality is also important for ecosystems health. Animals exposed to air pollutions can face similar complications to humans and plants face growth impairment and bioaccumulation |
Recreation
|
The creation of Lake Dunstan sold the town as a place of incredible recreational potential. In the 1980’s a professor from Canada, Dr Reiner Jaakson, reported that, with substantial and systematic investments into recreation, Lake Dunstan could become a hub for visitors all over the country and world to enjoy.
Since created 30 years ago, Lake Dunstan has fallen into a state of despair with weeds, rabbit holes and driftwood litter the shoreline. The visual aspect of the lake is substandard, native wildlife sparse and water-sports at risk of vanishing. |
Pests
|
There are 51 plants and animals found in Otago that are legally declared as pests under the Biosecurity Act 1993. All have been introduced to New Zealand since humans first arrived over 750 years ago.
Otago is one of the most biodiverse regions, covering 12% of the country. Home to many endemic species and complex ecosystems, Otago's biodiversity is important to our economy, culture, health and mental wellbeing. |
Biodiversity Loss
|
82% of plants and 70% of birds are only found in New Zealand. Cromwell was only dominated by tussock land, numerous kanuka-manuka scrubs and small forests of beech trees and totara.
The arrival of humans to New Zealand over 750 years ago has caused many NZ species to become extinct or critically threatened. Clearing hunting and farming nad introduced pests have destroyed ecosystems and led to the extinction of many plant, insect and bird species. |
