The State Emergency Service says it responded to more than 30 call outs in the Riverland over the weekend.

Most of the incidents were caused by fallen trees and branches, with several reports of flooding.

Renmark SES unit manager Fred Jones says he was called out after a camper spotted an empty houseboat drifting down-river towards Lyrup on Friday evening.

"We put our rescue boat in the river and went searching downriver to find it," he said.

"We actually found it in a back creek, so we anchored it to the river bank so it couldn't drift out into any of the boating channels."
