Raising Wallagamba Dam Walls Is ‘Single Most Effective Flood Mitigation Option’

Sky News host Chris Kenny said a report on the New South Wales flood crisis released this week confirmed that a 14-meter increase in Wallagamba Dam walls would have a positive impact on the Hawkesbury-Nepean region. says.

Kenny said the report showed thousands of homes in areas west of Sydney could be protected if the wall were to be taller and the dam turned into a flood mitigation dam.

“The region has been hit by five floods in the last few years with devastating consequences and massive restoration costs,” he said.

“However, as is always the case with such large-scale projects, the estimated $2 billion cost remains a problem, with the NSW government aiming to be half of the federal government.”
