The River Loxley is a river in the City of Sheffield, South Yorkshire, England. Its source is a series of streams which rise some to the north-west of Sheffield on Bradfield Moors, flowing through Bradfield Dale to converge at Low Bradfield. It flows easterly through Damflask Reservoir and is joined by Storrs Brook at Storrs, near Stannington, and the River Rivelin at Malin Bridge, before flowing into the River Don at Owlerton, in Hillsborough. The Loxley valley provided the initial course of the Great Sheffield Flood, which happened after the Dale Dyke Dam collapsed shortly before its completion in March 1864. Water supply The upper river is marked by the presence of four large reservoirs, used for the impounding of drinking water. Drinking water for the people of Sheffield was provided by five small reservoirs on a site close to Langsett Road. Others were added as the population grew, but by 1830, they could not keep up with the demand. Sheffield Water Company became responsible for water supply after an Act of Parliament was passed in 1830, and their first major reservoir was completed in 1836, when Wyming Brook was dammed to form the Redmires Middle Reservoir. Reservoir building continued as the population expanded further, and the Dale Dyke reservoir was nearly complete in 1864 when the dam failed, with catastrophic consequences for the communities below it. 250 people died in the flood, and many businesses were washed away or severely damaged. As a result of the compensation payments they had to make, the Sheffield Water Company obtained parliamentary powers to raise their water rates by 25 per cent. The company soon started other major projects, and Strines Reservoir was completed in 1869, covering and impounding 453 million gallons (2,059 Megalitres (Ml)) of water. Agden Reservoir was completed in the same year, which covered and held 559 million gallons (2541 Ml). The replacement Dale Dyke reservoir was completed in 1875. It covered the same area at Agden reservoir, and held 466 million gallons (2,118 Ml). When powers to raise the extra levy on water rates ceased in 1887, the Sheffield Water Company applied to parliament to make the charge permanent, and to make further increases to its charges. The Corporation of Sheffield decided that water supply should be in public ownership, and submitted a bill to buy the Water Company by compulsory purchase. Both sides fought for their cause vigorously,
