Nattai River Flood Study

Wingecarribee Shire Council recently engaged consulting engineers Catchment Simulation Solutions to undertake a flood study for the Nattai River catchment.


The Nattai River catchment occupies a total area of 6.75 square kilometres. The Nattai River Flood Study is the first step towards preparing a Floodplain Risk Management Study and Plan for the catchment.


The flood study was completed in early 2014 and subsequently adopted by Council in March 2014.
