Cabonne Council has confirmed it will investigate the incident and infrastructure at the site north of Orange.

Dax Clarke was with brother Mason, 8, and other children in kayaks when he became entangled in the side of the road over Lewis Ponds Creek which was swollen due to heavy rains.

"We were at Ophir and my canoe got stuck on the bridge where the car road is," he said.

"I got off, I pushed it away, I fell in and I got sucked under the bridge.

"I held my [life jacket] and then it swept me over to the other side.

"I was dragging my head against the top of it [culvert]."

His parents Wade and Rachel, from Springside, were about 25 metres away on the shore on Wednesday when they heard Mason scream after he tried to grab his little brother as he was swept under the road.

"He started screaming like a banshee," Mrs Clarke said.

"We realised we couldn't see Dax. I've never seen my husband run faster in his life.

"I don't ever want to hear my kid scream like that again," she said.

Mrs Clarke said Dax was under the culvert for about 20 seconds before he popped out the other side to their enormous relief.

She said he sustained cuts and bruises and was shaken by the incident.

"He said he thought he was going to die.

"He was upset," she said.

Mrs Clarke said the water level was over the top of the road due to rainfall around Orange earlier in the week flowing to Ophir.

Lewis Ponds and Summer Hill creeks meet at the Ophir Reserve.

Mrs Clarke has called for safety upgrades in the area including warning signs about being in the water.

"If they want families out there they have got to make it safe for them," Mrs Clarke said.

Mr Clarke said the creek was flowing strongly. "There is an under-current when it gets close to the bridge," he said.

The couple said they had not contacted police or ambulance but would contact Cabonne Council.

Cabonne Infrastructure deputy general manager Matthew Christensen said staff had found out about the incident and reported it.

"Council will be investigating the matter," he said.

Mr Christensen said council staff would also look at the infrastructure at the Ophir Reserve to assess whether any upgrades were needed.

He said they would need to consider whether the site was suitable for recreational water use.

Mr Christensen said making changes, including blocking the culvert, could create other risks and that would need to be assessed.
