Engineers were trying to drain the reservoir into the nearby River Goyt in an effort to reduce pressure on the dam. However, the Met Office has issued a warning that heavy rain and thunderstorms are expected in the area on Thursday evening, which will complicate efforts to protect the weakened structure.
Flood risk maps showed that if the dam burst it could leave parts of Whaley Bridge and many areas downstream along the river under up to 2 metres of water.
“There is a high probability that there will be significant flooding due to damage caused in recent severe weather,” a Derbyshire police spokesperson said.“There is a high probability that there will be significant flooding due to damage caused in recent severe weather,” a Derbyshire police spokesperson said.

Whaley Bridge is a thriving town right on the edge of the Peak District and part of the Dark Peak. It is bisected by the river Goyt, which runs down from Buxton and towards Stockport.

Built in 1831, the Toddbrook reservoir sits high above the town. It is a popular spot for sailing and open water swimming, and is dammed by a huge concrete wall that normally does not even have a trickle of water running down it. The walk along the path on top of the dam is popular with dog walkers and other locals, and provides a link to a busy skate park.Built in 1831, the Toddbrook reservoir sits high above the town.

Beneath the dam there is playground with zipwire and Memorial Park, created in 1920 to commemorate the loss of 108 local men in the first world war. There are houses on either side of the reservoir. Below it is the main town, which has a number of pubs, restaurants, a bakery and two chip shops, as well as a primary school and cricket club.

If the dam bursts, it may not only be Whaley Bridge under threat, but also the neighbouring settlements of Buxworth and Taxal, and potentially other villages and towns further down the Goyt valley.If the dam bursts, it may not only be Whaley Bridge under threat, but also the neighbouring settlements of Buxworth and Taxal, and potentially other villages and towns further down the Goyt valley.

“River levels in the river Goyt could rise rapidly as a result of water coming from Toddbrook reservoir,” the agency said. “Please be aware of your surroundings, keep up to date with the current situation, and avoid using low-lying footpaths near local watercourses.” “River levels in the River Goyt could rise rapidly as a result of water coming from Toddbrook reservoir,” the agency said. “Please be aware of your surroundings, keep up to date with the current situation, and avoid using low-lying footpaths near local watercourses.”
The risk comes from damage to an earth dam on the town side of the Toddbrook reservoir, where a spillway is designed to take excess water into the river Goyt. On Wednesday evening torrents of water had flowed straight over the barrier “like Niagara Falls”, according to witnesses. Waters subsided slightly on Thursday morning, revealing significant damage to the concrete structure that holds the dam in place.

Such earth embankment dams are at serious risk of being quickly washed away if the concrete spillways that protect them are damaged, according to Mohammad Heidarzadeh, an assistant professor of civil and environmental engineering at Brunel University London.
“In embankment dams, spillways are extremely important because they prevent embankment dams from overtopping,” he said. “Due to heavy rainfall in the Whaley Bridge area, the spillway is now broken and a big chunk of its concrete structure is damaged. There is a possibility that the spillway could then become fully broken in a few hours. If the spillway is fully gone, the embankment dam will be washed away very rapidly, which could cause a massive flood.”
Chris Gay, the commodore of the Toddbrook sailing club, which sails on the reservoir, said: “If you were there last night, it was just like Niagara falls. That’s obviously eroded the earth from behind the concrete slabs. The water level is still high and therefore probably – I’m no expert in this – but erosion is still taking place.”Chris Gay, the commodore of the Toddbrook sailing club, which sails on the reservoir, said: “If you were there last night, it was just like Niagara falls.

Gay, who lives just outside Whaley Bridge, said his wife, who was born and bred in the area, had never seen anything like the overflow at the dam in 60 years. “We’ve seen it trickling over, but we’ve never seen it in full force. It was pretty incredible; it was pretty shocking actually.”Gay, who lives just outside Whaley Bridge, said his wife, who was born and bred in the area, had never seen anything like the overflow at the dam in 60 years. “We’ve seen it trickling over, but we’ve never seen it in full force.

Edwina Currie, the former Conservative MP, also lives in the town. She told the BBC: “Evacuation is absolutely necessary. I don’t think they’ve got any choice. People are being advised not to take pictures. We are really very, very worried.Edwina Currie, the former Conservative MP, also lives in the town.

Jess, 20, was caught in the “mammoth” rain that flooded roads to “shin height”, according to posts she shared on Twitter. “I had my dog with me and as we crossed the road she almost got swept away, so I had to pull her across to me and pick her up,” she told PA Media. “I then waded through the rest of the water, about a foot and a half deep. I’ve never seen water that deep in such a residential area before.”Jess, 20, was caught in the “mammoth” rain that flooded roads to “shin height”, according to posts she shared on Twitter. “I had my dog with me and as we crossed the road she almost got swept away, so I had to pull her across to me and pick her up,” she told PA Media. “I then waded through the rest of the water, about a foot and a half deep.
