Environmental water top-up to help plants

Providing plants on the banks of the lower Goulburn River could encourage golden perch to migrate from the Murray River to the Goulburn.

Providing plants on the banks of the lower Goulburn River with a well-needed late summer drink could encourage golden perch to migrate from the Murray River to the Goulburn.

The Goulburn Broken Catchment Management Authority said ‘‘fresh’’ environmental water would be delivered along the Goulburn River below Goulburn Weir from late February and through March.

‘‘The annual monitoring that we’ve been conducting shows that using environmental water to ‘top up’ the water that is being delivered to irrigators and other users at this time of the year has helped bank-stabilising plants establish along the lower Goulburn,’’ Goulburn Broken CMA environmental water manager Simon Casanelia said.

‘‘And, because of this vegetation, we saw far less bank slumping and erosion during the natural flooding we experienced late last year than we did during 2010 to 2012.’’

Water for the increased flow is due to be released from Goulburn Weir from Sunday, February 26.

About 4600Ml/day will reach McCoy’s Bridge by March 9.

The flow will be well below minor flood level.

In the event of heavy rain, the timing and size of the environmental flow could change.
