With the building of the Ladybower Reservoir, adjacent to Howden Reservoir, the villages of Derwent and Ashopton were completely submerged. The packhorse bridge which once linked Derwent and Hope Woodlands was re-erected at Slippery Stones in memory of the late John Derry, editor of the 'Sheffield Independent' and a writer on Derbyshire. Hursthead Cote (1,280 ft), Crook Hill, Ouzelden Clough, are all on the western side of the Derwent Reservoir and can be reached by footpaths from the Glossop-Sheffield road. Back Tor (1,765 ft), Dovestone Tor (1,656 ft), and White Tor (1,599 ft), are the highest points of Derwent Edge and a track from the Glossop-Sheffield road runs along the ridge. These dams were used by Dr. Barnes Wallis and his team to test his bouncing bomb and the film 'The Dam Busters' telling this interesting story was shot here. Near Derwent Reservoir is a monument to 'tip' a sheepdog bitch who for 15 weeks guarded the dead body of her master who died in a blizzard.In recent years, forestry has become an important factor here and much of the sides of the Upper Derwent valley have been clothed in conifers. Fortunately the Forestry Commission are a relatively benevolent landowner who allow access and provide amenities for visitors, because this is a popular area for walking, cycling and fishing. They have an information centre and car-park at Fairholmes, just below Derwent dam, run in cooperation with the Peak National Parksee our ‘GALLERY’ for pictures
