Latrobe Valley Stormwater Study

Latrobe City Council engaged WMS Engineering to conduct an urban stormwater study across several locations within the Latrobe Valley, focusing on the townships of Traralgon, Morwell, Moe, and Newborough. The primary objective was to identify undocumented overland flow paths and assess areas requiring future maintenance works. This study provided valuable insights into flooding risks within key catchments, including the Traralgon Creek, Loy Yang Creek, Boyd’s Creek, Waterhole Creek, and Narracan Creek, which impact both urban and rural areas.

WMS Engineering completed a hydraulic analysis to evaluate the flooding nature in Traralgon, Moe, and Newborough, with further work planned for Morwell following the completion of the Waterhole Creek Flood Study. The findings revealed that several watercourses, such as Traralgon Creek and Loy Yang Creek, were causing flooding due to embankment overtopping and insufficient creek capacity. Similarly, Narracan Creek was identified as contributing to inundation along the Princes Highway and adjacent properties in Moe and Newborough.

The study helped Latrobe City Council prioritise areas for infrastructure improvements and maintenance, especially in flood-prone zones. This assessment provided critical information to mitigate flooding risks and improve flood management strategies for the Latrobe Valley’s urban development.
