It was a great field trip recently for the Upper House inquiry into the proposal to raise the Warragamba Dam wall. We were looking at the upper reaches of Kowmung and Coxs River at the entry of Lake Burragorang where inundation will occur up to 14 metres in a major flood event. 

The Committee was established on 20 June 2019 to inquire into  report on the NSW Government’s proposal to raise the Warragamba Dam wall.

Committee membership is as follows:
Mr Justin Field MLC Independent Chair
Hon Rod Roberts MLC Pauline Hanson's One Nation Deputy Chair
Hon Trevor Khan MLC The Nationals
Hon Shayne Mallard MLC Liberal Party
Hon Taylor Martin MLC Liberal Party
Hon Adam Searle MLC Australian Labor Party
