Environmental Watering

On 20 April 2016 the Renmark Irrigation Trust became the first irrigation body in Australia to enter a partnership with the Commonwealth Environmental Water Holder to return water to parts of the environment that have suffered long term degradation due to past irrigation practices.

To 30 June 2019 Trust has delivered over 500ML to five sites, inundating 84 hectares.

The regeneration of sections of floodplains also involves partnerships with Nature Foundation South Australia, the Renmark Paringa Council, the Renmark Paringa Landcare and local landholders.

“… the RIT is the first irrigation settlement in Australia, one of the first to be completely piped, and the first trust to partner with the Commonwealth Environmental Water Holder to deliver environmental water, they have long demonstrated the innovation and courage required to be world’s best”

SA Minister for Primary Industries and Regional Development Tim Whetstone

Environmental Watering Sites

The Trust has eight active environmental watering sites with a further seven to be added by 2022. The following listings provide a snapshot of each site noting the predominant flora in the area.

Active Sites

Johnson Waterhole

Johnson Waterhole May 2021

Johnson Waterhole was the first environmental watering site. During 2013-14, the Trust, in partnership with the Nature Foundation SA – Water for Nature and the local government commenced a project to deliver environmental water to Johnson Waterhole, initially using pumps and then the Trust’s water supply network.

Within three years of receiving yearly environmental water, the site transformed from a site dominated by Samphire to a wetland with a diverse range of native semiaquatic and floodplain plant species. The site is now ringed by patches of young eucalyptus and acacia trees and Lignum bushes.
