Four donkeys found themselves in a predicament on Monday morning.
State Emergency Service (SES) volunteers were called to the Wingecarribee River off Eridge Park Road to rescue the animals.
SES Wingecarribee controller Warren Turner said the job took between two to three hours, with six volunteers on the scene.
"I think the water came up around them and they went up to the island," Mr Turner said.

"They didn't want to move. They were up to their knees in water.
"They were forced to come across the river with a bit of help."
Volunteers had to contend with tough conditions, including cold water, debris and fences to rescue the animals.
Mr Turner said he was pleased to see a good outcome at the end of the rescue.
"Quite often at road crashes you don't get to see the end result," he said.
"This is probably one of the more rewarding jobs.
"You get to see the end result and the people who are directly involved."
Mr Turner said it was important for animal owners who find themselves in similar situations to proceed with caution.
"The main thing about animal rescues like that is the owners put themselves at risk for their animals," he said.
"The important thing is to try and get them out of the scene."
Call Triple Zero (000) if a domestic animal is in immediate danger or call the SES on 13 25 00 for farm animals.
While the rain has mostly settled down across the Southern Highlands, some hazards still remain.
Mr Turner urged residents to look out for falling trees, caused by this week's wet weather.
"Flood waters should be receding. The only risk at the moment is falling trees, there's been quite a lot," he said.
