Fly-tipping more than doubled during last year’s lockdown.
Figures show that between April and June in 2020, the council recorded 276 incidents across the region compared to 108 in the same period in 2019.
But just three cases in the region ended with a conviction or the offender being referred to the procurator fiscal.
The figures were unveiled following a Freedom of Information request by the Scottish Liberal Democrats.
The party’s environment spokesperson Molly Nolan said: “With refuse collections disrupted and tips closed for long stretches, there has clearly been an increase in incidents since the pandemic hit.
“Just at the moment where many of us gained a fresh appreciation for nature and our local environment, it was disheartening to see such carelessness towards it.
“Fly-tipping is destructive and can prove catastrophic for animals, plants and soil.”
The party contacted every local authority in Scotland and, based on the responses, discovered there had been nearly 130,000 fly-tipping incidents across the country between November, 2018, and November, 2020.
Dumfries and Galloway recorded 858 incidents with 366 cases in 2019. That rose to 463 in the first 10 months of 2020.
Only three councils used their powers to refer a total of 12 cases to the procurator fiscal. Three of those were in Dumfries and Galloway last year.
Ms Nolan added: “We need to see local authorities using the powers at their disposal to clamp down on this disgusting behaviour and ensure that repeat offenders especially feel the full force of the law.
The council was asked for comment.
