A reversal of events means some South Australian farmers are now battling floodwaters just weeks after their properties were burned in bushfires.

Growers and graziers in the state’s central northern region say they cannot believe things have turned so rapidly.

One man spoke to local news reporters about the quick change and how it could compound his issues.

Farmer Russel Zwar said his property was decimated during the month-long Bangor fire. He says he now risks losing the topsoil that he has left after being inundated with rain for several days.

“I was in the town... when it first started falling heavily” he said.

“I just saw a phenomenal amount of water coming off the paddocks, and some of it was more water than I've seen in a long time, if ever.

“The closer we got to home, I was getting pretty worried as to what we were going to see when the water subsided, but luckily it seems to have escaped it fairly well, which is relieving.

Earlier last week Adelaide experienced its wettest February day since 1969, with flooded roads and fallen trees keeping emergency services tied-up.

The Bureau of Meteorology had issued severe weather warnings for large parts of South Australia.

The rain was believed responsible for assisting human fire-fighters to take control of a long-burning blaze in the southern Flinders Ranges.

Very high fire dangers are in the forecast for rural parts of the state in the next few days.

Rain is forecast again toward the weekend.
