The River Mease is a lowland clay river in the Midlands area of England. It flows through the counties of Leicestershire, Derbyshire and Staffordshire and forms the administrative border between these counties for parts of its length.

The Trent is the third longest river in the United Kingdom. Its source is in Staffordshire, on the southern edge of Biddulph Moor. It flows through and drains the North Midlands into the Humber Estuary. The river is known for dramatic flooding after storms and spring snowmelt, which in the past often caused the river to change course.
