The story of the Upper Derwent Valley – where dramatic scenery meets wartime history, lost communities and one of Britain’s most significant engineering landscapes
For generations of walkers, cyclists and visitors, the imposing stone wall of Derwent Dam in the Upper Derwent Valley has been one of Derbyshire’s most recognisable landmarks.
Surrounded by sweeping moorland, dramatic gritstone edges and some of the Peak District’s most spectacular scenery, the reservoir attracts hundreds of thousands of visitors every year, drawn by its rich mix of outdoor adventure, wildlife and history.
Yet beyond all this, Derwent Dam also occupies a unique place in British history. It was here, overlooking these very waters, that one of the most remarkable military operations of the Second World War was rehearsed more than 80 years ago.
While the famous Dambusters raid took place hundreds of miles away in Germany, the story of Operation Chastise is inseparable from the landscapes of Derbyshire.
That connection was honoured recently as Severn Trent and the family of a late local historian donated a life-sized replica of the famous Second World War ‘bouncing bomb’ to the RAF’s legendary 617 Squadron.
Modern-day members of the Squadron travelled to Derwent Reservoir for a special handover ceremony at the site where crews prepared for the legendary Dambusters raid.
The replica had previously formed part of the former Derwent Dam Museum, established by respected local historian Vic Hallam in the 1980s.
Although the museum has been closed for around a decade, efforts by Vic’s family, Severn Trent and the RAF have now ensured the artefact will continue to educate and inspire future generations.
The replica will be transferred to RAF Marham in Norfolk, home of today’s 617 Squadron, where it will go on permanent display.
Flight Lieutenant Ady, an MBE recipient, representing 617 Squadron at the ceremony, believes the replica will serve as an important reminder of that legacy.
‘On behalf of 617 Squadron, I’m delighted to accept the handover of the replica UPKEEP mine,’ he said.
‘Its presence will be a constant reminder to all who work or visit the squadron of the significant history of the Dams raids – of the men who conducted the raid in 1943 and the innovation that the raid signified.’

Among those attending the handover ceremony were members of Severn Trent’s Armed Forces Network, including George Cook, a Bombardier with 1st Royal Horse Artillery.
‘We’re hugely proud of our links with the Dambusters at Severn Trent and this donation is a wonderful way to honour that legacy,’ he said.
‘It was a privilege to meet 617 Squadron members to talk about the Dambusters and discuss the valuable work of our group, which helps former service personnel to find fulfilling new careers in the water industry.’
For the family of Vic Hallam, the donation ensures an important piece of local history continues to be shared with future generations.
And for those who visit Derwent Reservoir, whether to walk its trails, admire its scenery or reflect on its past, the handover serves as a reminder that this tranquil corner of the Peak District played a remarkable role in shaping Britain’s history.
The site is equally significant for its engineering achievements.
Completed in 1916 and celebrating its 110th anniversary in 2026, Derwent Dam transformed the valley and remains a vital part of the region’s water infrastructure.
Today it forms part of a wider reservoir system that supplies drinking water to communities across not just Derbyshire, but neighbouring Nottinghamshire and Leicestershire too.
Yet the reservoir’s importance extends beyond engineering and military history. Beneath its waters lies another chapter of local history that continues to fascinate visitors today; the remains of the former villages of Derwent and Ashopton, communities that disappeared beneath the rising waters when the Ladybower Reservoir scheme was created in the 1940s.
Homes, farms, roads, a school and two churches were sacrificed as the valley was transformed into one of Britain’s largest reservoir systems.
Residents were gradually relocated before the villages were demolished, although some buildings remained standing for a time before eventually being swallowed by the expanding reservoir.
The church spire at Derwent became an especially poignant symbol of the lost village, remaining visible above the water for some time after inundation.
Today, little can be seen of the settlements, but their stories continue to capture the imagination. During periods of exceptionally low water levels, remnants of roads, foundations and other structures occasionally emerge from the reservoir bed, drawing curious visitors eager to catch a glimpse of the vanished communities.
On quiet days, it is hard to imagine that entire communities once occupied the valley floor.
The villages have become part of local folklore and are among the many reasons the Upper Derwent Valley attracts history enthusiasts as well as walkers, cyclists and nature lovers.
For many, the area offers a rare opportunity to experience layers of history within a single landscape — from the lost communities beneath Ladybower’s waters to the wartime legacy of the Dambusters and the engineering achievements that continue to supply drinking water across the Midlands.
More than eight decades after the Dambusters trained above its waters – and 110 years after Derwent Dam was completed – this fascinating and beautiful area remains a place where landscape, engineering and remembrance uniquely come together as a living monument, set within one of the country’s most celebrated outdoor environments.
The Upper Derwent Valley may lack the fame of some of our county’s headline attractions, but few places in Derbyshire can tell so many stories within a single landscape..
