Cowra Overland Flood Study and Plan

Overland flooding has been identified as a problem for a number of private properties in Cowra. An assessment of overland flooding was undertaken for two local catchments in Cowra, namely the West Cowra Drain and the Fitzroy Street local catchments. The West Cowra Drain catchment is located to the west of the Lachlan River and is comprised of rural, residential and light industrial properties. Flood-affected properties are residential properties in this area. The Fitzroy Street catchment is located close to Cowra town centre, and is comprised of residential and commercial land uses. Flood-affected properties in this area are commercial and light industrial properties.
