It was a nice day and I had time to kill so I decided to pop down the Errwood spillway
I wasn't expecting UU workers to be there but it's only a problem if they actually see you
Errwood Reservoir is a drinking-water reservoir in the Peak District National Park, within the county of Derbyshire and very close to the boundary with Cheshire. The reservoir was the second of two reservoirs built in the Goyt Valley, the other one being Fernilee Reservoir. It was constructed by the Stockport Water Corporation at a cost of £1.5 million, with work being completed in 1967; it is currently owned and operated by United Utilities. The reservoir provides drinking water for the town of Stockport and its surrounding areas, and it holds 4,215 million litres of water.
