The earliest records currently available indicate that the Armthorpe Internal Drainage Board was active in 1929.

The Board’s District lies within the area covered by Doncaster Metropolitan Borough Council. The main centre of population is the town of Armthorpe which lies entirely within the District.

The Board’s district covers some 1,151 hectares and they maintain some 6.95km of watercourse.

The Board maintained watercourses are all dependant upon gravity flow and all eventually discharge into watercourses which are currently the responsibility of the Environment Agency. The River Torne being the most important of these.
