- Not to be confused with the floods in Sheffield in 2007.
The Great Sheffield Flood was a flood that devastated parts of Sheffield, England, on 11 March 1864, when the Dale Dyke Dam broke.
Dale Dyke Dam
Sheffield is a city and subdivision of South Yorkshire, England. As the town industrialised, the population in Sheffield grew from 45,478 in 1801 to 185,157 in 1861. This rapid population growth resulted in the construction of the Dale Dyke Dam for the purpose of providing a more efficient source of clean water. It was created by the Sheffield Waterworks Company (SWWC). During the late 1850s, the company purchased land in the Loxley Valley to the northwest of town, on which to build a reservoir. By 1860s the dam and its associated works had been passed as satisfactory and it was allowed to fill with water.[1]
Collapse of Dale Dyke Dam
On the night of 11 March 1864, assisted by a strong south-western gale, the newly built dam, known as the Dale Dyke Dam, at Low Bradfield on the River Loxley, collapsed while it was being filled for the first time. An estimated 3 million cubic meters (700 million imperial gallons) of water swept down the Loxley Valley, through Loxley village, and on to Malin Bridge and Hillsborough, where the River Loxley joins the River Don. The flood continued south down the Don into Sheffield centre, around the eastward bend of the Don at Lady's Bridge, then to Attercliffe, past the sites of what would later become Don Valley Stadium, Sheffield Arena and Meadowhall Centre and on to Rotherham. A wall of water moved swiftly down the valley, destroying everything in its course. The centre of the town, situated on the hill to the south, escaped damage, although the densely populated district of the Wicker, around the new railway viaduct (constructed by the Manchester and Sheffield Railway), was completely destroyed.[2] The company's consultant engineer, John Towlerton Leather, was one of a family of worthy Yorkshire engineers who were involved in such work. His uncle, George Leather, had been responsible for reservoirs around Leeds and Bradford, and one of these was the scene of a dramatic collapse in 1852, when 81 people died.[2] John Leather and resident engineer John Gunson were working closely together during the construction of the dam. Leather designed the dam and oversaw its construction whereas Gunson directed and supervised the construction of the dam. Gunson was on site the night of the collapse and stated that there was a concerning crack in the outer slope of the embankment. Gunson convinced himself that the crack was not harmful but still took precautions by opening up the valves on the middle of the lol
to allow more water through.[2] Unfortunately these precautions failed to prevent the crack from worsening.
Aftermath
The mayor, Thomas Jessop, quickly set up a relief fund and the necessary help was provided for the homeless and needy. Sheffield was quickly supplied with aid wherever needed. The mayor ordered a meeting "For the purpose of considering and adopting such measures as may be deemed necessary to meet sufferings occasioned by this dreadful calamity",[1] raising over £4000. On 18 March 1864 the Mayor called another meeting, but this time it was for anyone who could afford it to give up one days wage to give to those in need. A relief committee was created, and in total over £42,000 was raised.
The company denied any problems relating to their structure and design of the dam, and believed that the cause of the crack and inevitably the collapse involved a landslide or landslip. A landslip being a geographical movement of land that usually results in the ground becoming unstable. Public perception, informed by the Coroner's court and the press, saw the collapse as due to a failure in the mode of construction of the dam. The professional inquiry was conducted and progressed to parliamentary investigations and institutional deliberations. The experts could not agree about the causes of the Dale Dyke collapse.[2] They noted that even with the cracks the collapse of the whole dam was unforeseeable. The corporation had found two men who either were or becoming president and then found five other engineers, all of whom had already been or about to become presidents of the Civils.[2] They thought that on the foundation of landslipping, they would pardon the Sheffield Waterworks Company from any carelessness and that the collapse of the Dale Dyke Dam was an unpredictable accident. They continued:
- We are moreover of the opinion that all the arrangements made by your engineers were such as might have been reasonably expected to have proved sufficient for the purposes for which they were intended and that, if the ground beneath the bank had not moved, this work would have been as safe and as perfect as the other five or six large reservoirs of the company which have so long supplied the town of Sheffield and the rivers Rivelin, Loxley and Don with water.[2]
As for the physical damage in Sheffield and all the nearby areas hit in this short space of time, 238 people were killed and some 700 animals were drowned; 130 buildings were destroyed and 500 partially damaged; 15 bridges were swept away and six others badly damaged.[2] The engineering profession at this time possessed a weekly journal, "The Engineer", that provided both an excellent contribution to the technical press and a platform of public relations. An editorial headed 'The Bradfield Reservoir' on March 18 of 1864 reflected the anxiety of the moment:
- Its fall, coupled with that of the failure of the Holmfirth reservoir...show that the practice of civil engineering is far from what it should be... That the forthcoming investigation will be of the most searching character there can be no doubt. [2]
A fortnight later, under the same title, it went on:
- The broken dam was constructed much according to the ordinary practice in such works. It failed nonetheless...That the Bradfield dam was lamentably defective no one can doubt... The Bradfield catastrophe, in its way, is a useful warning to the whole profession. [2]
The claims for damages formed one of the largest insurance claims of the Victorian period. Armageddon Online ranks this as the 20th most deadly flood in history, worldwide.[3]
Rebuilding
The collapse of the Dale Dyke Dam led to reforms in engineering practice. The court criticised the design and the construction of the dam. They focused on things such as the placing of the outlet pipes; the puddle wall thickness; the method by which the embankment had been built up from railway tip-wagons; the inadequacy of the overflow arrangements, and the practice of removing spoil for the embankment from the area to be flooded. [2] This then set standards on specifics that needed to be met when construction on building such large scale structures like the Dale Dyke Dam. The Dale Dyke dam was eventually rebuilt in 1875, but on a smaller scale. As for John Gunson, most of the blame fell on him, although the company recognised his loyalty by retaining him in its service until he died in 1886.[2] The Government started a Board of Inundation Commissioners to pass judgement for compensation claims against the Waterworks Company. They also arbitrated 7,500 claims for loss of life and property which totalled £455,000. All but 650 claims were settled without recourse to the arbitration process, but those 650 claims took almost six months to process. The claims registers record the claimant, their marital status and address, as well as details of the claim and the outcome, and amount awarded in compensation. They provide a unique insight into mid-Victorian Sheffield's trade and industry with claims listed for stock, tools and premises damaged and lost. The claims for furniture, clothes, books, toys and household utensils and goods help build up a picture of workers' lives at the time. [1] A flood memorial stone marks the site of the original dam wall and footpaths to explore the area.[4]
