In the last newsletter, Mark presented a table comparing rainfall at Mt William (Duwul) to surrounding towns on the plains - Ararat and Hamilton. The Mt William weather station is the highest in southwest Victoria, at an elevation of 1150 m above sea level, and...
In our recent mid-month special update on the impacts of the Grampians bushfire, we also shared NGT's perspective on the water needs of the upper Wannon River in its post-fire recovery phase. As we explained in that recent article, since 1971 the river has had...
This is the final - and arguably most important - of the three stories in our special mid-month "bushfire edition" of the NGT Newsletter. The Wannon River alluvial fan burns as the Grampians fire approaches the Walker Swamp Restoration Reserve. Photo: Todd Burger As you are probably...
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...
