History of Flooding in Calderdale




Earliest flood on record. Elland Bridge is destroyed.


Similar to 1615.  Bridges are damaged.


Ripponden Parish Church and Stirk Bridge destroyed.


Flooding level reaches ‘highest ever’.

16 Nov 1830

Newspaper report simply noted “A great flood at Todmorden".

Early 1831

Walls in the lane leading to Christ Church Todmorden were washed away in a deluge.

29 Nov 1834

A great flood did considerable damage in Todmorden and neighbourhood

22 Dec 1837

Hebden Bridge suffered “the highest flood recorded” so far when water levels reached a massive nine feet in places. Reported an observer: “The water was within half an inch of reaching the surgery of Mr John Thomas.”. “The arches of the canal viaduct at Black Pit were unable to take the waters which consequently rose to the height of the canal and ultimately flowed over it.

The waters thus dammed back formed an immense lake out of which many of the houses stood up in a pitiable condition. It is said that someone passed in a boat from the canal over the walls of New Road to the White Horse Inn.

August 1855

In Todmorden around 5pm “the rain poured down in torrents filling the different brooks which wind their way through the valley.” Terrifyingly, a 15-yard high “wall of water” then rushed down the turnpike road, inundating homes and properties including the National School. “The meadows in the neighbourhood presented the appearance of a vast lake.”

26 Oct 1855

“Todmorden was visited by one of the largest floods within the recollection of the oldest inhabitants.” A wall opposite Wadsworth Mill came crashing down and the overflowing Calder turned Burnley Road into a river. Hebden Bridge escaped relatively lightly but at Mytholm “the water rose to the exact height as during the flood of 1837.” Green’s Mill, Portsmouth, suffered serious damage in the torrential downpour and a joiner’s shop at Gauxholme was “swum away.”

6 Aug 1857 

A child drowned in the swollen River Hebden followed a week later by a “considerable rise” in the River Calder resulting in “great damage” in Todmorden and Hebden Bridge.

7 Aug 1859

Another catastrophic rise in the Calder caused devastation in Hebden Bridge when the river rose “a foot in less than ten minutes,” turning open ground from Salem Mill to the White Horse Hotel into a vast lake.

The same floods also wrought havoc in the Cheapside, Pavement and Salford areas of Todmorden – “nearly covering the looms in Mr Chambers’ mill;”

6 Nov 1860

There was “notable flooding in the town and below,” heralding a decade in which it never seemed to stop raining.

8 Sept 1861

The whole of the Upper Valley suffered “one of the greatest floods ever experienced”

17 Nov 1866

Recorded as the second highest flood after 1775. High-water mark left in Walton Street, Sowerby Bridge.


Further flooding

July 1870

Three people lost their lives when Burnley Valley and areas as far afield as Bacup were inundated. This was generally accounted the worst flood of the century.

8 Dec 1874

According to the Todmorden and Hebden Bridge Historical Almanack “some of the dwellings were flooded to a depth of from 4 or 5 feet.”


Cobden was “visited by one of those floods which are of frequent occurrence in that locality.”

15 July 1877

"Dangerously high” floods spread from Blind Lane down through Roomfield and Sandholme to the centre of Todmorden, filling basements rooms. “The area over which the water spread was probably wider than in any known flood in Todmorden.”

Oct 1877

Unlucky Cobden residents remained under water for nine days.

17 May 1879

A “very heavy thunderstorm” was recorded but not, apparently, followed by the dreaded floods.

Dec 1880

“Serious flooding” was reported in Todmorden, Hebden Bridge and Mytholmroyd: the Hole in the Wall, Hebden Bridge, was inundated to a depth of four feet and the Dusty Miller, Mytholmroyd, to 3ft 8ins – “only eight inches lower than the great flood of 1837,” it was noted.

1 Jan 1881

Heavy rains caused a landslip on the hillside above the railway line between Todmorden and Dobroyd.

13 Dec 1891

Callis Bridge wrecked. Highest flood since 1866.


Photo of flooding at Gandy Bridge, Todmorden. No further details.

12 Nov 1901

Walls between Callis Bridge and Hebden Bridge demolished. Footbridge over Calder at Stubbins washed away. Worst flood since 1866 in middle and upper reaches of the valley.

10 Feb 1920

Severe flood in upper reaches (Todmorden and Mytholmroyd). Walls in Mytholmroyd knocked down.


Whole of the Calder Valley suffered when the heavens opened so suddenly people were taken completely unawares. Hillside streams turned into raging torrents and low-lying land from Luddenden Foot to Todmorden was inundated. The water subsided as quickly as it had risen and a massive mopping-up operation began: it was noted that the Calder appeared to be subject to serious flooding every 10 years or so.

1922, 1923 & 1928

Mytholmroyd suffered the worst of the flooding in the Calder valley.

Also, 3 properties on Rochdale Road at the junction with Strines Street flooded from Ramsden Clough.

21 Jan 2008

Walsden flooding affected the railway cutting at Deanroyd Road worse than in 2012/3. Rochdale Road, Todmorden, was closed between the A646 Burnley Road and the junction with Inchfield Road, Walsden, due to flooding. Areas around Centre Vale Park were flooded, along with properties on Burnley Road near Todmorden High School.

19 Nov 2009

Surface water caused cellar flooding on commercial street, Todmorden, with additional flooding of roads in Walsden.

22 June 2012

Major flooding across the Upper Valley down to Brighouse. River Calder and River Hebble overflowed causing major damage. This flood event was the largest fluvial event (fluvial flooding happens when rivers burst their banks because of sustained or intense rainfall) on record across the Upper Calder Valley, and the third largest across the lower reaches of the River Calder. Rainfall raised river levels all along the River Calder and filled all available storage. From midday onwards, steady rainfall continued to fall. More than a month’s rainfall fell in the 24 hours of the 22nd of June. The rivers rose to unprecedented levels causing the worst flooding since 2000. Over 900 properties and businesses were affected by the resulting flooding when Walsden Water, the River Calder, various tributary rivers and the Rochdale Canal burst their banks. Hebden Bridge recorded its highest ever river level (3.311 metres) and Mytholmroyd saw levels over 4.9 metres. Some properties flooded to a depth of over a metre.

As well as the flooded premises, there was structural damage to road surfaces, culverts and bridges, plus major disruption to traffic and local people, including the railway line, stranding many people in transit.

The towns and villages most affected were Walsden, Todmorden, Eastwood, Hebden Bridge (including major flooding at Callis, Woodland Villas and Charlestown), Mytholmroyd and Brearley/Luddendenfoot.

There was also flooding in other parts of the Borough, such as in Sowerby Bridge, Elland and Brighouse.

9 July 2012

Flash floods in Hebden Bridge, Eastwood & Mytholmroyd. Three weather systems hit the area on the 9th July, causing torrential rain to fall on already heavily saturated ground, and resulting in major flooding incidents across the Upper Valley, with over 43mm of rainfall. This caused surface water flooding but did not result in high river levels.  Again, saturated ground caused water to run off the hillsides. Nutclough dam overtopped and there was extensive flooding in Keighley Road. Rubble and silt from the hillsides blocked drains and culverts. Around 100 homes and businesses suffered, some for a second time.

25 Aug 2012

Again, flash flooding affected the Jumble Hole area from Blackshawhead to Callis Bridge, causing additional flooding to properties across the Upper Valley. Substantial quantities of silt and rubble were deposited in Burnley Road and surrounded nearby terraced properties. The drainage system on Burnley Road was unable to cope and the Fire Service spent several hours pumping water into the river.

31 Dec 2012

Flooding caused by run-off down Hebble End was avoided in Market Street, Hebden Bridge, due to CMBC staff and volunteers working together to divert the flow and keeping drains and street gullies clear of debris.

29 July 2013

Large storm clouds brought heavy rainfall to the Upper Valley which was affected from a number of sources.  The communities worst affected were those immediately adjacent to Walsden Water and the River Calder, impacting on Walsden, Todmorden and Hebden Bridge.  Two watercourses located above Kershaw Road Walsden were unable to cope with the level of flow and suffered severe erosion, overloading and blocking the drainage system. Excess surface water from the damaged culverts spilled onto the railway line at Walsden Station, flooding properties along Rochdale Road. Birks Clough overtopped, and this water combined with excess rain run-off from surrounding hills then flooded properties along and adjacent to Burnley Road.

8 July 2014

Rain in Elland caused highway disruption and 1 property flooded.

19 Dec 2014

Surface water caused 9 properties across the area to suffer some degree of flooding, with a further 6 properties narrowly missing being flooded.

31 Mar 2015

Ripponden Old Bank is closed following localised flooding as a result of a blocked culvert.

14 Nov 2015

Extensive rain caused road closures due to flooding on Burnley Road, Todmorden, Centre Vale Park was used as a flood plain. Flooding on the road also occurred at Eastwoods, Mytholm, Mytholmroyd, Brierley, Kebroyd on the Halifax Rd to Ripponden, Burnley Rd just outside Hebden Bridge, Burnley Road in Todmorden and the A58 near the junctions with the A641 and at Chain Bar due to localised flooding.

Some premises suffered minor flooding especially due to run-off from hilltops.

12 Dec 2015

Surface Flooding throughout. Walsden, Cornholme, Todmorden, Callis, Hebden Bridge, Mytholmroyd, Sowerby Bridge and Brighouse. River levels on the River Calder were high but breached only in Sowerby Bridge. River Hebden breached flooding Oldgate in Hebden Bridge and contributing to the flooding in Market Street. Roads suffered from surface rain water and drainage systems unable to cope.

In Hebden Bridge serious flooding was avoided due to CMBC staff and volunteers working together to divert traffic and keeping drains and street gullies clear of debris.

26 Dec 2015

Over Christmas and Boxing Day, Pennine areas had over 60mm of rain fall in 24 hours and some locations had over 100 mm. Many of these locations had already seen over twice their usual amount of rainfall in December and this followed an extremely wet November. Many locations along the River Calder saw highest ever recorded river levels.

The flooding on 26 December 2015 occurred when rivers rose rapidly because the ground was already saturated from previous heavy rain. Many of the Environment Agency's measuring stations recorded the highest river levels ever seen. In excess of  2,781 homes and 4,416 businesses were seriously affected with a building washed away in Mytholmroyd and Elland Bridge seriously wrecked. In addition to this a number of substations, schools, roads and bridges were also damaged. Unlike previous floods, communities further down the valley including Sowerby Bridge, Elland and Brighouse were also seriously flooded.

21 Nov 2016

Excess rain running from the tops caused surface water flooding in several locations across the Valley, in particular Mytholmroyd and Hebden Bridge. Crisis was averted in several locations thanks to the efforts of local volunteers though a small number of suffered minor flooding especially due to run-off from hilltops.

16 Mar 2019

Flooding of residential properties, business premises, railway infrastructure and the highway was experienced at several locations throughout Calderdale. Although river levels responded rapidly they did not exceed maximum levels recorded. The storm event was preceded by prolonged rainfall resulting in a saturated catchment.

27 Jul 2019

The Environment Agency issued flood warnings across the Upper Calder Valley and sounded the flood sirens. Surface water flooding led to a number of road closures, including roads into Todmorden. There were some cases of cellar flooding in homes.

7 Nov 2019

Heavy rain caused surface water issues across Calderdale and the closure of the A646 at Callis Bridge following a prolonged period of rain. There were no reports of flooded properties other than some cellar issues.
