Chelmarsh Reservoir is a water supply reservoir located in the village of Chelmarsh, Shropshire. The reservoir is operated by South Staffordshire Water and was created in 1963 to augment the supply of water in a large area of South Staffordshire and the Black Country. The main source of water to the reservoir is from abstraction from the River Severn.
The reservoir is the main source of supply for Sedgley beacon service reservoir that feeds potable water to some parts of Wolverhampton. Chelmarsh Reservoir attracts many species of wild birds.
