Turton and Entwistle Reservoir Claimed

Turton and Entwistle Reservoir in the village of Edgworth. The reservoir owes its existence due to the Entwistle Dam. When constructed in 1832 the Entwistle Dam was the highest in Britain; rising 108 feet from the base. The reservoir contains almost 750 thousand imperial gallons (roughly 3,400,000 litres) and, with the Wayoh Reservoir just below, satisfies around 50% of Bolton's need for drinking water.

The dam is 108 ft high and 110 metres long at the crest. The present overflow channel and valve tower were added in 1864.
