Toddbrook Reservoir Rebuilt After Near Catastrophic Failure

By the Editorial Team · Sunday, September 6, 2026

The Toddbrook Reservoir in Derbyshire has completed a £50 million rebuild including a new spillway after its dam nearly failed in 2019, prompting evacuations due to flood risks. This restoration aims to ensure the reservoir’s safety during extreme weather and seismic events while reopening the area for public use and water management across England’s canal network.

The Toddbrook Reservoir in Derbyshire, England, has undergone a £50 million reconstruction project following the near failure of its Victorian-era dam in 2019. The dam’s structural instability, triggered by heavy rainfall, prompted the evacuation of more than 1,500 residents from the nearby town of Whaley Bridge amid fears of catastrophic flooding.

In August 2019, emergency response teams, including personnel from the Royal Air Force, mobilized to reinforce the dam with temporary measures that successfully held back floodwaters threatening the town. As part of the emergency operations, thousands of fish were relocated to Worcestershire to protect local wildlife, including a notable specimen known as ‘Bertie,’ a barbel that gained local attention.

The reservoir serves as a critical water source, feeding 220 miles of canals across England. The comprehensive rebuilding effort featured the installation of a large new spillway engineered to safely divert excess water into the River Goyt during extreme weather. Designed to withstand flood events considered to be a "one in a million year" occurrence, as well as earthquakes, the spillway reflects advances in hydrological and seismic engineering sought to prevent future emergencies.

The multidisciplinary project drew on expertise from hydrologists, structural engineers, and seismic specialists, aiming to restore not only the dam’s integrity but also the surrounding environment. Plans include the conversion of parkland adjacent to the reservoir back into a children’s playground, enhancing recreational opportunities for the community. Local residents have expressed optimism about the reservoir’s reopening for fishing and leisure activities, though some have called attention to ongoing concerns regarding reservoir maintenance and risk management.

With the reservoir now beginning to refill, officials consider the restoration a significant step toward ensuring long-term safety and utility. The project underscores the challenges of managing aging infrastructure amid changing climate conditions and highlights the necessity of rigorous oversight and updated engineering solutions for critical water resources.
