Torr weir was built across the Goyt, to provide a head for the Torr Mill which occupied the same site. Torr Mill burnt down in 1912.
On 20 September 2007 Torrs Hydro New Mills Limited, an Industrial and Provident Society for the benefit of the Community was formed, with shares were offered later in that year. Construction began on March 2008, and on 8 June the screw was delivered. It weighs 11 tonnes. Commissioning started in August and the scheme was handed over on 4 September 2008. Torrs Hydro has an agreement to sell its electricity to The Co-operative Group which uses it to power its businesses, including its supermarket in New Mills, Derbyshire.
