Earlier this year, I wrote an article on how long it takes water to flow through the upper Wannon River, drawing on comparisons from the 1980s and more recently in 2022. The Wannon River catchment begins in the Grampians National Park and influences important wetlands...
Over the past three years, as part of an investigation into the ecology and hydrology of the Wannon River, whose catchment begins in the Grampians National Park in Victoria, we've had the opportunity to really grow our understanding around freshwater fish distribution and movement in...
The Wannon River catchment begins in the Grampians National Park and influences important wetlands like Brady Swamp, Gooseneck Swamp and NGT's Walker Swamp Restoration Reserve along the way. We have been investigating the Wannon River system for a few years now, through our study into...
The Yarra Pygmy Perch (Nannoperca obscura) is a small freshwater fish (the biggest one I have seen was 78 mm in length). It is endemic to coastal waterways of south-eastern Australia and prefers slow flowing habitat along the edge of streams and rivers, and also...
If you are a regular reader of our newsletter, you'll know we have been investigating the Wannon River system for a few years now, which begins in the Grampians National Park and influences several important wetlands, such as Walker Swamp and Brady Swamp. You can...
Over the past few years we have been investigating flow patterns in the upper Wannon River, and providing comparison to past data. This investigation is part of a three year project and important for the future health of the Wannon River, which is the main...
It happened so long ago that it has been all but forgotten in recent years, but back in the 1960s the proposed diversion of the upper Wannon River's headwaters off Mt William in the Grampians was a source of great concern to many people in...
It's shaping up to be another "half-decent" year for wetlands around the southern tip of the Grampians. Despite a very dry autumn and winter, spring rains arrived to get the catchment running. The Wannon River has been flowing south of Lynchs Crossing Rd since mid-August...
What a pleasure a recent week spent in the field was. Not only did I have a chance to repeat a survey that NGT's Lauren Brown initiated six years ago, I've also revisited what feels like a past life. During my time at Deakin University,...
In the south west of Victoria we are currently experiencing one of the wettest winters for a long time. Driving across the landscape, it has been quite revealing to see lots of wetlands showing their face, and many streams running at levels usually seen in...
