HARC was engaged by Campaspe Shire Council to review and update the Rochester Flood Management Plan following the devastating 2022 flood, which impacted more than 1400 homes (over 80% of the town).
The project involved development of a contemporary hydrologic and hydraulic modelling framework for the 3,390 km² Campaspe River catchment, calibrated to the three largest recorded floods (2011, 2022 and 2024).
The models were used to investigate a broad range of structural and non-structural flood mitigation measures, including Lake Eppalock operating arrangements, levees, retarding basins, drainage improvements and property-level resilience options.
Working closely with Campaspe Shire, North Central CMA, VicSES, Goulburn-Murray Water and the Rochester community, HARC delivered a robust evidence base to support future floodplain management, emergency management planning, and investment in flood mitigation measures for one of Victoria’s most flood-affected communities.
