GOLDEN and silver perch will benefit from environmental flows due to be delivered along the lower Goulburn River next month.
Commonwealth Environmental water holder, David Papps said, “Native fish are a barometer of river health. The more we understand about the things that fish such as golden and silver perch need to reproduce, survive and thrive, the healthier the whole system will be.
Goulburn Broken Catchment Management Authority Environmental water manager, Simon Casanelia said,
“Over the years we have refined the timing of flows to get the best spawning response, with mid to late spring being the most effective. The last time we were able to deliver an environmental flow at this time of the year was 2014 as last year natural flooding was occurring and the previous year, due to the very dry conditions and low water availability, the environmental flow was cancelled.”
Water for this spring’s environmental flow, peaking at 5,500ML/day, is due to be released from Goulburn Weir from November 15. The environmental flows will also act as a trigger for other native fish to move, breed and find shelter; provide increased shelter for water bugs; and improve water quality.
“This all helps crayfish, shrimps, water bugs and native fish continue to recover after the naturally occurring blackwater event that happened earlier this year after a summer storm,” Mr Casanelia said. “Irrigators appreciate better water quality too and of course, now the weather has warmed up, more people will be out and about on and by the river boating, fishing, bushwalking and birdwatching.”
