Ladybower Reservoir is one of Derbyshire’s beautiful tourist attractions and a great day out.
But did you know the reservoir hides a secret?
A very big secret, the size of two villages, to be exact.
The distinctive Y-shape construction of the reservoir, along with its sweeping views across shimmering waters makes it a unique place to explore.
However Ladybower Reservoir’s history tips it into the realms of ‘unique Derbyshire heritage’.
Ladybower Reservoir started life in 1935, a project spearheaded by Derwent Valley Water Board to fulfil needs of the wider East Midlands.
To make this happen, two villages of Ashopton and Derwent were flooded.
It may seem somewhat drastic to flood inhabited villages, but it was a huge undertaking from the then Derwent Valley Water Board who facilitated relocation of residents to nearby Derbyshire villages.
Ashopton buildings were pulled down before the reservoir was filled, although structures remained intact in Derwent village.
Remains of Derwent village can be seen today when dry spells and extreme drought make the village ruins visible from the concrete A57 road bridge.
