The modern dam replaced an older dam, which was situated around 100m to the S. The first dam, marked on the OS 1st edition map, is now under the water level of the present reservoir. The reservoir today covers 129 acres and has a capacity of 1,632,690 cubic metres. Work on the dam was possibly carried out in 1939. At NS 5555 4944 there is a dam tunnel, on the NE side of the dam. It contains a sluice and pipe that drew off water to supply the nearby farm lands. It was built in 1939 and originally had a clock gauge to monitor the water being extracted. This is no longer present.
