Overview The Corangamite Catchment Management Authority is seeking provision of services for the remediation of the East Barwon River Constriction, located approximately one kilometre downstream of Birregurra-Forrest Road, Barwon Downs, Victoria. About Channel constriction at the site is the result of encroachment by invasive willows over many decades, which has resulted in an increased frequency of overbank flooding. Scope The scope includes: Removal of approximately 500 metres of willows extending along the East Barwon River Selective removal of willow rootballs to restore channel capacity and flow Construction of six floodplain re-entry erosion control points along an adjacent floodplain drainage channel Creation of five intermittent shallow clay bunds to reduce the frequency of overbank flows Minor vegetation management within three small floodplain wetlands on site, including removal of willow and invasive wetland vegetation
