About the watering

Up to 3 GL of Commonwealth environmental water was made available for use in Jimaringle, Cockran and Gwynnes creeks in the Edward-Wakool river system, New South Wales, during 2012-13..

Commonwealth environmental water will be delivered in conjunction with up to 3 GL of water supplied by the New South Wales Government. Commonwealth environmental water will be delivered in spring 2012. The use of environmental water in Jimaringle, Cockran and Gwynnes creeks will:

  • Provide flows to maintain and improve water quality within the creeks, particularly salinity.
  • Maintain and improve the health of native plant communities in the creeks including river red gum, black box and lignum.
  • Contribute to providing good quality habitats in which native animal communities, such as the pobblebonk frog, Peron's tree frog and wrinkled toadlet, can successfully breed and grow.

The use of Commonwealth environmental water helped to build on the outcomes of environmental water provided to the Jimaringle and Cockran creeks in previous years.

Landholders along these creeks continue to be key partners by generously sharing their time, knowledge and experience during the planning, delivery and monitoring of these watering actions.

Environmental water delivery was managed by the New South Wales Office of Environment and Heritage, in cooperation with the Commonwealth Environmental Water Office, Murray Catchment Management Authority, State Water Corporation and Murray Irrigation Limited.

What makes this place so special and why is Commonwealth environmental water used here?

  • The Jimaringle and Cockran creeks area includes woodland habitats for more than 100 different type of birds, including the grey-crowned babbler, diamond firetail, hooded robin and bush stone-curlew.
  • These creeks also provide habitats for many other native animals including the large-footed myotis, a fishing bat that uses its long claws to catch spiders, fish and other prey from the surface of the water.
  • Strong ongoing community support to restore the Jimaringle, Cockran and Gwynnes Creeks to a healthy system that will benefit the community and the environment.

Environmental watering in Jimaringle-Cockran Creek autumn 2012

3 GL of Commonwealth environmental water was delivered to the Jimaringle-Cockran Creek in the Edward-Wakool River System, New South Wales, during March and April 2012. Commonwealth environmental water was delivered in conjunction with 3.2 GL of water supplied by the New South Wales Government.

The environmental water was used to provide a follow up watering following the successful watering of the creek system in autumn 2011. The watering action aimed to improve water quality and continue to improve the health of the vegetation in the system, in particular the aquatic vegetation and fringing river red gum and black box communities.

The water delivery was monitored by the Murray Catchment Management Authority in conjunction with the NSW Office of Environment and Heritage. This watering action was managed in cooperation with the New South Wales Office of Environment and Heritage, Murray Catchment Management Authority, State Water Corporation, and Murray Irrigation Limited.
