BUSINESS owners in Roma were caught off guard late Wednesday night when another heavy deluge caused Railway Dam to burst its banks for the second night in a row.
Many businesses and homes in the centre of town experienced flash flooding after 65mm of rain fell in less than half an hour.
Police blocked roads to stop vehicles travelling through the floodwater and pushing more water into shops and businesses.
The Reject Shop store manager Trish Jamieson said the damage would have been more manageable except for inconsiderate motorists.
"We were in the middle of night fill when the rain hit, so we were lucky we were here when it happened," she said.
"The most frustrating part was whenever someone drove past to have a look they just pushed more water in."
Council workers and fire crews spent yesterday morning cleaning up mud and debris scattered throughout the town.
Downstream at St George, river levels are expected to exceed the major level of six metres at the weekend with a major flood peak expected early next week of at least 7.5m.
The week's rainfall on the Darling Downs, however, has come as a blessing for farmers.
The dry November followed by this week's rain has given wheat farmers enough time to harvest while also allowing them to use the same fields for other crops.
Cecil Plains farmer Graham Clapham said because of the rain he can now begin looking for other produce to farm.
"With the amount of rain we have had on the wheat fields we just harvested, we should be able to get a good crop of soy beans going over the summer months," he said.
Mr Clapham said as long as the rainfall was not as heavy as last year, this summer could be very prosperous for farmers around the Darling Downs.
