AMY Reis, a Gladstone resident from Marten St, woke to discover she was stuck in her house with water up to her doorstep on Thursday.
It was even deeper in her driveway, not allowing her to leave for work.
"The engine in my car is now shaking and smells really bad. I wish I was at work now because it will probably cost a bit to fix," Ms Reis said.
The drain across the road had blocked in the early hours on Thursday morning, causing water to bank up over the road and almost into the residents' homes.
It was unblocked by 9am by Gladstone Regional Council staff.
ABC News reports several residents in Gladstone spent the night at makeshift accommodation because their properties had been inundated with raw sewage.
Manholes are being held down by sandbags on several streets.
Gladstone Mayor Gail Sellers said it was not yet clear how many properties were affected.
"There are a few problems but at the moment we have it well under control," she said.
