Reservoirs Yorkshire Water allows recreational use of some of 113 of its 120+ reservoirs. Activities include walking, fishing, horse riding, cycling, water sports and bird watching. Several sailing clubs are afforded the use of certain reservoirs for their sailing activities, including Boshaw Whams, Embsay, Grimwith, Ponden, Scar House, Thornton Steward, and Warley Moor Reservoirs. Since privatisation of the water authorities in 1989, Yorkshire Water has made many of its locations accessible to the public, which not only cover water, but woodland and moorland. Walks exist around Brayton Barff, Fewston, Grimwith, Langsett, More Hall, Scammoden, Thruscross, and Undebank reservoirs. Additionally, in 2008, Yorkshire Water teamed up with long-distance walking writer Mark Reid to create the Yorkshire Water Way, a walk which takes in Yorkshire Water Reservoirs along its route.
