Police and SES were called to the Wollondilly River crossing on Gurrundah Road, some 10km west of Goulburn at about 9am.

SES Argyle cluster commander Rob Bell said the man had driven into the flooded crossing and become stuck. The water was half-way up the vehicle, which police said was a silver Hyundai iload.

The man was standing on his car door at one point.

While an SES crew positioned itself on the Goulburn side, Police Rescue accessed the site from the Crookwell side.

Police Rescue officers used a boat to reach the vehicle and hook on a tow rope. They pulled the car out at about 9.40am.

They had earlier called on a nearby landowner to communicate with the man to make sure nobody else was in the car.

The man, aged in his 20s, and originally from Columbia, was not injured. He had been working on a property in the area.

Mr Bell expressed his frustration with people driving into flooded crossings.

"That is my biggest concern," he said.

Goulburn Airport registered about 42mm on Tuesday and Wednesday. The deluge flooded creeks and crossings and closed a host of roads, particularly in the Upper Lachlan Shire.

On Wednesday at 10am, Mr Bell said the Wollondilly River at Towrang Bridge was at 3.1m, well over the structure.

"The Mulwaree Ponds is holding at the moment but the Wollondilly River is right up," he said.

"We expect that to go down this afternoon but we're waiting for the runoff."
