Just a year after the Black Summer bushfires touched the town, residents of the Snowy Valleys Council area are this week dealing with flooding following torrential rain.
Adelong received around 90mm of rain, causing damage to the Adelong Creek banks.
Meanwhile, 104mm of rain forced the evacuation of caravans and campers at the Tumbarumba Caravan Park.
Snowy Valleys Council CEO Matthew Hyde said the floodwaters are subsiding, but it is unclear when the holiday-makers may return.
"The flood waters are going down, but it's a matter of watching the alerts now," Mr Hyde said.
"We are still expecting rain and that typically comes in the afternoon."
Teams of council workers are now in the process of assessing the damage around the town. Mr Hyde said early indications suggested there could be a big clean-up ahead.
"There's been some damage to road corridors with trees down, some roads are closed," Mr Hyde said.
"It's a matter of keeping safe and getting around to assess the damage."
Due to the intensity of the rain on Friday night, Saturday's Tumbarumba Cup has had to be cancelled.
An announcement was made on Saturday morning via the turf club's Facebook page saying stewards had assessed the grounds and found them unfit for the races after the downpour.
