Last year we shared the story of how NGT tried to seek a common-sense outcome for the upper Wannon River in the Grampians National Park. If you'd like to understand how that rather unfortunate sequence of events unfolded, then you can find those stories listed...
Back in August last year, I explained in detail the water policy and bureaucratic hurdles that had left the upper Wannon River 'stranded' during the 2025 flow season. This unfortunate sequence of events slowly unfolded over several months, after the entire river within the Grampians...
BackgroundBack in June, I shared the story of the belated refusal of NGT's request of the Victorian Government (submitted five months earlier) to consider altering the regular operation of the Wannon Diversions this year, in response to the impact of the Grampians bushfires on the...
It has taken more than six months to get there, but I have now had a decent look at the upper Wannon River following the summer bushfires. My greatest fear through this wait was that any significant rain would mobilise soil and ash, decimating the...
Environmental Science students from Deakin University, Warrnambool, recently visited NGT's Walker Swamp Restoration Reserve. The visit was part of their ‘Catchments to Coast’ unit, exploring the biological and physical characteristics that shape interconnected freshwater, estuarine and marine systemsArriving at Walker Swamp, the students delved into...
For regular readers of the NGT newsletter, you might recall that we initiated a discussion earlier in the year about the impact of the diversions on the headwater streams of the upper Wannon River. We did so in the context of the unprecedented situation we...
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...
