Floods come to an end in NSW after record 177 days

The Darling River at Burtundy in western NSW dropped below minor flooding levels this week, prompting the agency to drop its last remaining warning after 177 days.

Three successive La Ninas contributed to the state's second-wettest year on record in 2022, with 863.6mm falling across the NSW - 55 per cent above average.

Since the first flood warning was called on September 14, 2022, NSW SES conducted more than 960 flood rescues, delivered more than two million sandbags to residents protecting their homes and undertook more than 1000 resupply missions to isolated communities.

NSW Commissioner Carlene York thanked SES volunteers for assisting communities during the floods.

"The floods across southern and western NSW have devastated many communities," she said.

"It has been the longest and largest flood event in the history of NSW.

"I am so proud of everything that our members did ... in supporting our communities. They did a great job, they were there when they were most needed, they put their lives at risk many times."

Already-saturated catchments exacerbated conditions, giving rise to fast-moving and often unpredictable floodwaters.

Eugowra in central-western NSW was almost wiped off the map after an inland tsunami swept through the town in November, destroying or damaging 90 per cent of its buildings and killing two residents.

In total, seven people died during the flood event and 157 homes were destroyed with another 2816 left uninhabitable. More than 3960 emergency warnings were announced.

An international contingent from Singapore and New Zealand was called in to assist with the flood efforts, the first time such a step had been taken in the state's history.
