The New South Wales flood inquiry has stopped short of recommending raising the Warragamba Dam wall, listing the $2bn-plus project as just one option governments have to reduce flood risks in Sydney’s Hawkesbury-Nepean valley.

The inquiry’s report, released on Wednesday by the state government, identified pros and cons of raising the wall of Sydney’s main source of drinking water by 14 metres. The project was not one of its 28 recommendations.
