James Watts sold the land for the reservoir to Stockport Corporation for £64,000 and a further £756,000 was borrowed for the construction. This equates to around £5.5 million and £64 million today. Brumhead and Rangeley’s book, ‘The Kinder Reservoir and Railway’ charts the amazing saga of the construction and contains a comprehensive collection of photographs, drawings and maps. The centenary of it opening was held at the base of the dam in May 2012.
