Dozens of people were rescued from floodwaters in the state’s central west this weekend – including a first-time mother whose waters broke while she was isolated as the Lachlan River inundated the town of Forbes.

Mamata Pun Rama and her partner Chitra were among thousands affected by the flooded Lachlan River at Forbes, where several streets in the central business district were inundated, along with many residential streets and homes.

Mamata’s waters broke on Friday night, and the Western NSW Local Health District sent a treatment pack across the river to an off-duty midwife, Judi, who advised it was time to go to hospital.

State Emergency Service personnel were able to evacuate the family in a high-clearance vehicle to Forbes Hospital, where baby Imaan was born on Saturday.

“Little Imaan came into the world this afternoon, much to the delight of both his parents and the hospital staff who supported the couple throughout the birth. We’re pleased to confirm mum and bub are doing well,” the Western NSW Local Health District said in a statement on Saturday.

“Congratulations to Mamata and Chitra, who are over the moon and now enjoying plenty of cuddles with little Imaan, who is blissfully unaware of the incredible circumstances surrounding his delivery.”

The Lachlan River peaked at Forbes late on Saturday, reaching a depth of just under 10.7 metres, slightly below the record set in 1952.

Floodwaters are still moving west along the course of the Lachlan River, with major floods taking place at Jemalong, Euabalong and Condoblin. The State Emergency Service warned residents of Euabalong and Lake Cargelligo to prepare for evacuation.
