The aqueduct carrying water from Haweswater Reservoir to Heaton Park Reservoir in Manchester follows the line of Longsleddale underground on the east of the valley, and crosses Stockdale Beck by a pipe bridge. Construction of the aqueduct was started in the 1930s and finally completed in 1976. Survey columns can still be seen on Branstree, Tarn Crag, and Great Howe below Grey Crag. The tunnel is about 2m by 2m in section, and the water flow is by gravity. Between Haweswater and Manchester the tunnel only deviates from a straight line by less than.
Possible railway route
When the directors of the Lancaster and Carlisle Railway were choosing its route in the 1840s, one possibility considered was a route through Kendal and along Longsleddale, with a 2-mile tunnel under the Gatescarth Pass into Mardale and thence towards Bampton. This route had the support of the Kendal Committee of the Lancaster and Carlisle Railway; other alternatives under consideration included a line over a barrage across Morecambe Bay and round the Cumbrian coast, routes bypassing Shap to the east and west, and the Shap summit route finally chosen. After a lengthy Parliamentary inquiry the longer and steeper route over Shap Fell was chosen. Thomas Bouch was approached to be an adviser on the Longsleddale route and if this route had been chosen, in all probabilities Thos. Bouch would have been appointed as the civil and railway engineer. Bouch was the engineer for the Cockermouth, Keswick and Penrith Railway and rose to fame in later years, for it was his design of the Tay Railway Bridge that was destroyed in a severe storm. The gradient of the Longsleddale route would have been somewhat less than the 1 in 70 gradient of the climb up and over Shap Fell, and the use of banking engines could have been reduced if not entirely eliminated. It has been said that the Longsleddale route, "had it ever been built, would have been as dramatic and awe-inspiring as any in Britain".
Recreation and community
In 1974, an Outdoor Pursuits Centre was founded by Jim McVeigh as an access point for young people, from in and around Manchester, to the great outdoors. Over the years, this has extended to young people from all around the country. Unlike many outdoors centre in the UK, this is staffed and operated solely by volunteers. The centre's Adventure Activities Licensing Authority licence allows staff to run outdoor activities including: rock climbing, caving, ghyll scrambling, hillwalking and archery. There are few community buildings in Longsleddale. There is one village hall that is known as the Community Hall and one church - St Mary's - which is near the centre of the valley and is open every day. Services are on the second and fourth Sunday of each month at 10.30am. The village was the inspiration for the fictional village of Greendale in the BBC children's television seriesPostman Pat.
