Environmental watering in the Edward-Wakool River System 2012-13

Commonwealth environmental water was made available for use in the Edward-Wakool River System during 2012-13 for the watering actions listed below.

Status

30 June 2013: These actions have been completed.

Edward River, Wakool River, Colligen and Yallakool Creeks

28,943 ML of Commonwealth environmental water was delivered between October 2012 and April 2013 and was expected to contribute to the following outcomes:

  • support the movement, breeding and recruitment of native fish (such as Murray cod, and golden and silver perch)
  • support the habitat requirements of native fish and other native species including frogs, turtles and invertebrates
  • support ecosystem functions that relate to the connectivity of habitats along the watercourse.

The use of Commonwealth environmental water will help build on the outcomes of environmental water provided to the Edward-Wakool River System in previous years.

3,000 ML of Commonwealth environmental water was used in Jimaringle, Cockran and Gwynnes creeks in the Edward-Wakool river system during spring in 2012-13. Additional environmental water for this event was supplied by the New South Wales Government.

The use of environmental water in Jimaringle, Cockran and Gwynnes creeks contributed to:

  • providing flows to maintain and improve water quality within the creeks, particularly salinity
  • maintaining and improving the health of native plant communities in the creeks including river red gum, black box and lignum
  • 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.

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.

2,000 ML of Commonwealth environmental water was used in Tuppal Creek during 2012-13. Commonwealth environmental water was delivered in conjunction with up to 2,000 ML of environmental water supplied by the New South Wales Government.

Environmental water was delivered in spring-summer 2012 to:

  • provide flows through the system to maintain and improve water quality within the creek, particularly salinity
  • maintain and improve the health of native plant communities in the creek including river red gum, black box and lignum
  • contribute to providing good quality habitat, and support the breeding and recruitment of native animals, particularly frogs.

Tuppal Creek had not previously received environmental water. Landholders along Tuppal Creek are key partners, who kindly shared their time, knowledge and experience to enable environmental water to be delivered to the creek for the first time.
