Environmental flow regime for the lower Collie River Wellington reach

Research and analysis
Report on the development of an environmental flow regime for the lower Collie River between Wellington Reservoir and Burekup Weir, referred to as the Wellington reach
Last updated:

Using this study, we aimed to formalise winter releases from the dam, replacing the current scour regime with an environmental release regime to maximise the ecological benefit.

The study informed water resource planning and management decisions in the Lower Collie surface water allocation plan, which defined the amount of water available for abstraction in the lower Collie River, developed a licensing scenario for water entitlements from the reservoir and specified an environmental flow regime to replace the winter scour regime for the reservoir.
