The SES has advised residents in flood-affected areas to leave sandbags in place, with the weather bureau forecasting further rain between Sunday and Tuesday.
It said the threat of flooding had reduced around the Gawler and Wakefield rivers, north of Adelaide.
The towns of Virginia, Two Wells and Lewiston suffered flooding yesterday and overnight, damaging a number of properties.
Extensive sandbagging in Port Wakefield prevented any major damage to the town when the Wakefield River burst its banks yesterday.
Sandbagging continued through the night after 60,000 sandbags were flown into the Edinburgh RAAF base on Saturday afternoon.
Emergency crews from Western Australia and Victoria as well as Australian Defence Force personnel are assisting SA crews on the ground.
