Two walkers rescued from NSW flooded river

Two bushwalkers have been rescued after becoming stranded at a flooded river near Orange in the NSW Central West.

NSW emergency crews and police carried out the rescue overnight when the bushwalkers found themselves on the wrong side of the river, SES said.

Floodwarnings had been issued by the SES for the area with Belubula River set to peak on Thursday afternoon and heavy rain forecast in the area for Friday as well.

The SES continues to stress the importance of not approaching flood waters.

"The SES has already carried out 450 flood rescues in New South Wales this year, and we haven't even reached storm season yet," said SES's Terri Langendan.

She said the public need to stay clear of all flood waters, campers should avoid camping too close to creeks and rivers and people need to drive to conditions.

"People not only risk their own lives, but risk the lives of others too," she said.
