Why the UK's Most Famous Reservoir Has Massive Sinkholes

Discover the fascinating engineering behind the famous plugholes at Ladybower Reservoir in the heart of the Peak District. In this video we explore everything about the incredible plugholes, sinkholes, spillways and bellmouth overflows that make this dam one of the most unique reservoirs in the UK. Also known as bellmouth or “morning glory” spillways, these huge circular drains control the water level of the reservoir by allowing excess water to flow through massive vertical shafts and tunnels before being released into the River Derwent below the dam. Each plughole is around 24 metres (78 ft) wide with a drop of around 20 metres, making them both an engineering marvel and a spectacular sight when they overflow.  Located near Derwent Dam and surrounded by stunning Peak District scenery, the plugholes attract photographers, drone pilots and visitors from all over the UK—especially during winter when heavy rainfall causes the famous whirlpool effect as water disappears into the spillways. If you love engineering, dams, reservoirs, drone footage or the Peak District, this is one location you won’t want to miss. 📍 Location: Ladybower Reservoir, Derbyshire, England 👍 Don’t forget to like, comment and subscribe for more drone footage, interesting places and hidden engineering wonders across the UK. #LadybowerReservoir #Plughole #PeakDistrict #Derbyshire #Spillway #DamEngineering #DroneFootage
