Bonnie Doon Catchment

The catchment is heavily urbanised with medium density residential developments in the upper catchment, and higher density residential, light industrial and commercial developments in the lower reaches downstream of Bonar Street. The study area also includes the Eve Street Wetlands. The main discharge to the Cooks River is via the Bonnie Doon Channel through Cahill Park. A flood study for this catchment was completed by BMT WBM in 2017 and WMA Water is currently reviewing the Floodplain Risk Management Study. A draft report for this study will be publicly exhibited in 2022.
