Editing Mytholmroyd (section)

==Flooding==
The village is currently (2017/18) under development with the [[Environment Agency]]'s 35 Million pound Mytholmroyd Flood Alleviation Scheme. This includes raising the height of flood walls on the banks of the River Calder and Cragg Brook, as well as demolishing homes and businesses on the Calder's banks to widen the river. The village's post office has been relocated to flood-proof premises, with other buildings being stabilised and strengthened. Caldene Bridge, upstream from County Bridge, is being demolished and relocated as well as the bridge at Greenhill Industrial Estate.

===1837===
A disastrous flood occurred in 1837; few details are known about it, although it is known that the river reached the height of the canal, built on the hillside, and ultimately overflowed it.<ref>{{cite web|url=http://eyeoncalderdale.com/it-s-water-under-the-bridge-mytholmroyd-1946|title=Eye On Calderdale|work=EyeOnCalderdale.com|access-date=5 February 2017}}</ref>

===1946===
In the worst flooding to ever affect the village, many properties suffered flood water up to the second storey, and the village remained underwater for almost 12 hours. Two shops on Burnley Road collapsed into the river, shops just doors down from the buildings that collapsed in the 2015 flood. By 8 am, flood waters reached up to 7 feet.

===1954===
On Saturday, 21 August 1954, almost 8 years since the devastating 1946 flood, a flash flood devastated the village once again; the river rose by more than 6&nbsp;ft in less than two hours, with flood water entering properties at over 2&nbsp;ft every 15 minutes. The Dusty Miller Inn had almost 4&nbsp;ft of water in its bar area. Flood alleviation works in the 1960s uncovered that County Bridge was standing on foundations untouched since the wooden bridge 17th century, so as part of the works the bridge's foundations were quickly filled with concrete.

===2012===
A flash flood occurred in July 2012, when a downpour lasting just 90 minutes devastated the village. This was a repeat of another flash flood of June, in the same year, where more than 50&nbsp;mm of rain fell causing the River Calder to burst its banks. More than 5,000 properties were severely damaged in the [[Upper Calder Valley]]; many businesses lost insurance and consequently many never recovered.

===2015===
Mytholmroyd was severely affected by the [[2015–16 Great Britain and Ireland floods|Boxing Day floods in 2015]], when the [[River Calder, West Yorkshire|River Calder]] and the canal both rose to cover the valley floor, and consequently the town centre of Mytholmroyd. It was the highest ever recorded river level. Hundreds of homes and businesses were devastated, with some buildings still empty in 2017. The row of shops north of County Bridge partially collapsed into the river, and £10 million was earmarked for future protection of the village.<ref>{{cite web|url=https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/525893/Mytholmroyd_Action_Plan_FINAL.pdf|title=Mytholmroyd Flood Alleviation Scheme|date=May 2016|website=assets.publishing.service.gov.uk - Environment Agency|access-date=24 November 2019}}</ref> The whole row of shops which partially collapsed have been fully demolished, along with homes along the riverbank at Calder Grove. By 2018, Russell Dean Furnishers had their furniture showroom above ground level and the [[Co-op Food]] built a replacement store.

===2020===
On 9 February 2020, [[Storm Ciara]] caused a month-and-a-half's worth of rain to fall on Mytholmroyd within 24 hours. This caused widespread flooding.
