Environmental flows aim to provide water to achieve specific outcomes such as enhanced biodiversity or to provide insurance against drying due to climate change. How those flows are delivered, how the benefits that arise from those flows are measured and the potential role for citizen science in that assessment are current areas of research worldwide. This project will quantify the ecological benefits of environmental flows from a recently decommissioned reservoir in the Painkalac River, Victoria, Australia. This will be through developing and testing a scientifically-robust regime for quantifying environmental flow benefits that includes citizen science in partnership with ecological specialists. The project is a partnership between the Centre for Regional and Rural Futures at Deakin U
