Wayoh Reservoir is a water reservoir in the town of Edgworth, Lancashire, England. It was completed on 28 April 1876 to supply water to Bolton.{{cite web|url=http://www.theboltonnews.co.uk/archive/2007/03/27/1867+to+1887+(anniversary_1867to1887)/1287367.Moments_in_time_1877___1879/|title=Bolton News Archive|accessdate=7 February 2010}}{{cite web|url=https://www.geograph.org.uk/photo/327439|title=geograph.org.uk|accessdate=7 February 2010}} Wayoh, together with the Turton and Entwistle Reservoir, make up 50% of Bolton's drinking water.{{cite web|url=http://wikimapia.org/697909/Wayoh-Reservoir|title=Wikimapia.com|accessdate=7 February 2010}}

In 1962 in response to an increasing demand for drinking water in Bolton, a treatment plant was built and the reservoir enlarged to its present capacity of {{convert|501|e6impgal}}. Today the treatment plant can supply almost {{convert| 10|e6impgal}} of drinking water per day.

The reservoir is crossed by the earlier built Armsgrove Viaduct; which was built between 1847 and 1848 by the Blackburn, Darwen and Bolton Railway to bridge Bradshaw Brook.{{cite web|url=http://www.northturton.com/walks_res.html|title=northturton.com|accessdate=7 February 2010}}
