Lower Broken Creek

Status

2 December 2013: This action is in progress.

About the watering

The purpose of this watering action is to improve and maintain the ecological health and resilience of the system. Commonwealth environmental water will contribute in-stream base flows and freshes between August 2013 and May 2014 within the lower Broken Creek in support of native fish reproduction and condition, hydrological connectivity and the maintenance of water quality. Return flows from the use of Commonwealth water in the lower Broken Creek will support downstream actions throughout the Mid Murray, Lower Murray, Coorong and Lower Lakes, contributing to the protection, maintenance and improvement of the diversity and condition of water dependent native flora and fauna and ecosystem function.

This watering action will use up to 59,500 ML of Commonwealth environmental water, subject to water availability within the Victorian Murray and Goulburn catchments. It is being managed in partnership with the Victorian Environmental Water Holder, Goulburn-Murray Water and the Goulburn Broken Catchment Management Authority.

Upper Broken Creek

Status

2 December 2013: This action is yet to commence.

About the watering

Commonwealth environmental water will contribute to an in-stream fresh between August 2013 and March 2014 to support improved native fish condition, hydrological connectivity and biotic dispersal.

Up to 121 ML of Commonwealth environmental water has been made available for use within the Upper Broken Creek, subject to water availability within the Broken catchment. This watering action will contribute to achieving the following expected outcomes:

  • contribute toward flow variability
  • provide a wet dry zone at the channel edge
  • maintenance of aquatic habitats during periods of cease to flow
  • promote successional change in community composition through disturbance and habitat diversity.

This watering action is being managed in partnership with the Victorian Environmental Water Holder, Goulburn Broken Catchment Management Authority and Goulburn-Murray Water.
