Murray Darling Basin Authority Projects

A team from the Murray Darling Basin Authority (including its CEO Andrew McConville and a number of key technical staff) visited a number of
the project sites along Water Gully on 19 April. This visit was part of an information gathering exercise to inform the current revision of
the Murray Darling Basin Plan due to be released later this year, with the group wishing to better understand water issues and water
management options in the Upper Namoi watershed catchment area.
Around 80% of the water which flows in the lower basin comes from upper watershed catchments like ours (which represent only 15% of the land
area) and MDBA recognise that without well managed watersheds there can be no long term water sustainability for the Basin as a whole.
The Water Gully sequence of projects which are aimed at stabilising the drainage and slowing water flows out of one part of the Wallabadah
subcatchment (from above the Racecourse 4kms through the village to the Quirindi Creek) are now recognised as one example of drainage
management practices that may be widely applicable to the many other watershed catchments along the Great Dividing Range, and the MDBA
team were interested in seeing and understanding their impacts for potential inclusion in the revised Plan.
“When we see projects like this it really helps us to get a good understanding of what’s possible” commented MDBA CEO
McConville.
