A dam that has stood for over a century has now sparked an emergency in southern Spain, forcing the evacuation of 11,000 individuals from their properties because it comes simply inches from its capability, elevating fears it may collapse. Montejaque Dam has stood for 102 years as a spectacular engineering failure, hidden amongst the mountains above Ronda in inland Andalusia.
As Storm Leonardo battered the province, the dam, which has lengthy been dubbed the “Ghost Dam” by locals, was immediately dropped at life this weekend. The massive subterranean cave programs which have drained the Embalse de Montejaque reservoir for a century lastly choked up, placing immense pressure on the limestone gorge. Consequently, Brits have been amongst a whole bunch of individuals to be urgently evacuated from the Spanish vacation hotspot amid fears that it may burst its banks. 200 individuals have been rapidly rushed from the Estacion de Benaojan neighbourhood after terrified residents reported feeling the bottom “tremble” from water gushing by way of limestone caves beneath their properties.

Nevertheless, in an replace on Monday, the variety of individuals evacuated has soared to 11,000 individuals because the 36 cubic hectometre reservoir – equal to 14,400 Olympic-sized swimming swimming pools – reaches its restrict.
In keeping with The Olive Press, a Ronda police supply mentioned: “They’re nervous concerning the dam, actually nervous. Whether or not it may well maintain or not. It’s now at 1 / 4 of a metre from the highest – it seems to be prefer it’s quickly going to return over.”
“There may be additionally the query concerning the 2,000 evacuated from Grazalema and the bedrock of close by Benaojan collapsing,” they added. “The dam has by no means gotten that prime and given its 100 years outdated everybody may be very nervous about it.”
“The query is, is there a option to let the water out safely earlier than it breaks. It’s a nerve-wracking day right here.”
In the meantime, a supply from GREA, the emergency centre coordinating the response, mentioned there are “actual fears” the dam may not maintain.

Commissioned in 1924 by the Sevilla Electrical energy Firm, Montejaque Dam took simply 9 months to construct and now stands 272 ft (83 metres) excessive. Coming at a time when hydroelectric energy was heralded as the long run, Swiss architect Grüner was employed, who selected to utilise bolstered concrete quite than the standard masonry blocks of the nineteenth century. This allowed for a curved design that directed water’s stress into the canyon partitions quite than relying solely on the sheer weight of the partitions.
It was the primary of its sort in Spain and, on the time, the very best dam within the nation.

Nevertheless, Grüner and his staff failed to grasp that the Sierra de Grazalema is a karstic area, not strong rock. The limestone mountains are like a sponge. Moreover, straight beneath the dam’s foundations was the Hundidero-Gato system – one of many largest and most complicated cave networks in Europe. As such, irrespective of how a lot it rained, the water merely disappeared, escaping quickly by way of the porous rock and rising miles away on the Cueva del Gato (Cat’s Cave). By the Nineteen Forties, the undertaking was deserted.
As an alternative, for the previous 80 years, the dam has served as a vacationer hotspot for hikers and a nesting floor for the griffon vultures. Nevertheless, the specter of Storm Leonardo has led to the dam’s infamous “plughole” being sealed over a century after its building.
