Commonwealth environmental water was used in conjunction with NSW government environmental water. The environmental water helped fill lakes, wetlands and connect waterways in the area. It built on the outcomes achieved for previous environmental watering undertaken by the NSW government and contributed to:

  • maintaining the health and regeneration of native plant communities in Cherax Swamp, Yarrawol Creek and Narwie West, Reed Bed and Black Box wetlands.
  • the establishment and growth of native plant communities in Hobblers Lake and Penarie Creek which have been isolated from the floodplain and have not received environmental water before.
  • providing good quality habitat for native animals including waterbirds, fish and frogs.

This watering action was managed in cooperation with the NSW Office of Environment and Heritage, NSW State Water and local landholders. It was delivered using new infrastructure funded by the NSW government and the Australian Government Biodiversity Fund. This includes the use of carp screens which helped prevent the movement of adult carp, a pest species, into key areas.

Monitoring the outcomes from this environmental watering action was done by the CSIRO, the NSW Office of Environment and Heritage and Charles Sturt University. The monitoring focused on the effect of environmental watering on native birds, fish, frogs, plants and water quality.
