reconstructed as the Sedgwick Gunpowder Company. From 1886, Henry Swinglehurst was the director of the company, which became a private limited company in 1896, when he died and his son Addison took over. Explosive Trades Ltd bought the business in 1917, and they became part of Nobel Industries Ltd in 1920. ICI became the parent company in 1926, but falling orders led to its closure in 1935. After closure, many of the buildings were burnt or demolished to ensure there were no traces of explosive left. The site was reused during the Second World War for the storage of ammunition, and ownership passed to the National Trust in 1950, when they acquired Sizergh Castle and its grounds. The site was altered in 1977, when Low Wood Caravan Park was established, but it remains one of the best-preserved gunpowder works in the north. Among the caravans, the remains of nine incorporating mills, some corning mills, an engine house, a dusting house, glaze houses, stove houses, a press house, a pump house, a boiler station, a saltpetre refinery, stables and a joiner's shop, and much of the water management system which supplied waterwheels and a water turbine, can still be found. The site is an ancient monument while some of the detached buildings are grade II listed. The final mill was Basin Ghyll or Basingill Mill, which was located below Force Bridge at Sedgwick. It was located on the east bank of the river, and was unusual, in that it was not a complete gunpowder works. It was built in 1790 to supplement the incorporating mills at Old Sedgwick gunpowder works. When that closed in 1850, and operation moved to Gatebeck, Basin Ghyll supplemented the incorporating mills at Gatebeck. It closed in 1935, after which all the wooden-framed mill buildings were burned to remove explosives, leaving the stone blast walls. There was a waterwheel at the north end of the site, and a tunnel which carried water downstream to further mills and a second waterwheel. Most of the basic structures and the water system survive. Hydro power In addition to the Staveley Mill Yard hydro-electric scheme, there have been other proposals to use the Kent to provide hydro power. In 2009 the residents of Kentmere proposed the construction of a small system, utilising a section of the river just above Low Bridge, where it drops some over a distance of at Jumb
