A Canberra man has died after his car was caught in floods near the Cotter Dam.
Police found the 37-year-old from Kambah about 4.30pm on Sunday but were unable to retrieve the body until Monday morning.
Police spotted the man's vehicle after they were called out to a separate incident involving two men who had been four-wheel driving and realised they couldn't cross the swollen river.
While emergency workers were trying to work out how to rescue the man, his four-wheel drive was swept away by the floods and flipped over.
The man's body was seen shortly after on an island in the middle of the river.
"The floodwaters yesterday ... were extremely strong, savage, with a lot of debris, large logs coming down the river," ACT Policing Sergeant Harry Hains told reporters in Canberra.
"The force was enough to flip a two-tonne ute."
Police and emergency workers warn people not to drive through floods for any reason.
"These types of weather conditions, extreme weather conditions we've experienced do lead adventure-seeking type people to seek mud with their four-wheel-drives," Sgt Hains said.
"There is no risk worth taking to cross a flooded river to go and seek some piece of dirt to drive your four-wheel-drive on."
