Wyangala Dam wall may be raised by 10 metres from 379 m to 389 m to give greater water security for residents and farmers along the Lachlan River (See article here).
The existing dam covers 5,435 ha. Raising the dam wall by 10 metres would increase the area of inundation to 7,343 ha (+35%).
This modeling was done using a 5m Digital Elevation Model (DEM) sourced from the Elevation Information Model (ELVIS) provided by Geoscience Australia (See link here).
