In this in-depth exploration of Australia’s ancient past, we reveal the untold story of how powerful earthquakes transformed the course of the Murray River, the country’s longest and most iconic river. Approximately 45,000 years ago, a series of seismic events along the Cadell Fault created a massive uplift in the landscape, damming the Murray River and blocking its flow for thousands of years. This natural damming led to the formation of vast lakes and wetlands like Lake Moira and Barmah Lake, and forever altered the geography of the Murray-Darling Basin.

Through geological evidence, we explore the impact of these earthquakes on the surrounding rivers, including the Goulburn, Edward, and Wakool Rivers, and how the Tallygaroopna palaeochannel formed as ancient pathways that allowed water to escape. These channels, along with the famous Barmah Choke, played a critical role in redirecting the flow of the Murray as it struggled to find a new path across the altered landscape. The story of Lake Kanyapella, a large lake sustained by meltwater and river flows from the Goulburn’s prehistoric pathways, is just one of the fascinating natural features shaped by these dramatic events.

Join us as we uncover the lasting environmental and ecological impacts of the Cadell Fault uplift on the Murray-Darling Basin. You’ll learn about how this powerful seismic activity contributed to the creation of Australia’s unique ecosystems, from the Barmah-Millewa Forest to the sprawling wetlands around the Cadell Fault, which the Murray eventually navigated through to reach Lake Alexandrina, which serves as the Murray River’s final outlet to the sea. Through cutting-edge research, we’ll bring to light how ancient rivers and lakes, which no longer exist today, once played a pivotal role in shaping the landscape we now recognize.

Perfect for enthusiasts of geology, Australian geography, and natural history, this video will walk you through the scientific evidence and provide you with a visual journey of the Murray River’s transformation. Discover how seismic forces and natural damming events can change the course of history, reshape entire ecosystems, and leave a legacy that impacts modern landscapes.
