NSW government ordered to revisit world heritage assessments for Warragamba Dam expansion

A leaked report has found WaterNSW did not adequately assess how the project could affect iconic species such as the platypus and echidna

The New South Wales government has been ordered to redo world heritage assessments for its proposed raising of the Warragamba Dam wall after a federal analysis found it had failed to consider the impact on iconic species including the platypus.

A leaked report by federal environment bureaucrats found government agency WaterNSW did not adequately assess how its plan to raise the dam wall by 17m could affect the world heritage values of the Blue Mountains.
