The River Dearne is located in South Yorkshire and flows through the areas of Barnsley, Doncaster, and Rotherham. It is a tributary of the River Don and stretches around 30 miles (48 km) in length. The river’s catchment area has been significantly shaped by past industrial activities, particularly coal mining.
In recent years, efforts have been made to improve the river’s water quality and manage flood risks. The valley of the Dearne now hosts several nature reserves and parks, offering both ecological benefits and recreational spaces for residents.
