Europe's drought crisis has forced northern countries to confront a startling reality: they may need more reservoirs. As extreme dry spells grip the continent, nations that once mocked Spain's obsession with dams are now questioning their own water infrastructure.
For over a century, Spain has been building reservoirs at a frantic pace, becoming the fifth country in the world by number of dams and the first in the EU. The Franco era, in particular, left an indelible mark on the Spanish landscape with massive hydraulic works. For decades, northern Europe looked on with condescension, viewing Spain's fixation on concreting rivers as an oddity. But now, as drought hits home, that perception is changing.
The Drought That Changed Everything
The UK just experienced its driest July in 190 years. According to the Environment Agency, England received only 10% of its average July rainfall (1991-2020 baseline). In the southeast, rainfall didn't even reach 1%. Areas like Hampshire, the Isle of Wight, and West Sussex went 59 consecutive days without rain—a shocking statistic for a country famous for its drizzle.
August brought little relief: by the 13th, only 4 mm of rain had fallen, just 6% of normal. The result is stark: 71% of England's territory is affected, and 45 million people live in officially drought-stricken areas. Of these, 27 million are under temporary hose pipe bans. British reservoirs are at critically low levels, and water restrictions are becoming the new normal.
Why Northern Europe Envies Spain's Reservoirs
Spain's extensive reservoir network, built over a century, provides a buffer against dry spells. While northern Europe has traditionally relied on abundant rainfall and groundwater, climate change is altering that equation. The drought of 2022 has exposed the vulnerability of systems designed for a wetter past.
In contrast, Spain's dams allow for water storage during wet periods, ensuring supply during droughts. This infrastructure, controversial as it may be, is now seen as a strategic advantage. As rivers run dry in the UK, France, and Germany, the question arises: should these countries invest in similar storage capacity?
- Spain has over 1,200 major dams, the most in the EU, providing significant water storage capacity.
- The UK's driest July in 190 years left 45 million people in drought-affected areas.
- Northern Europe's water systems were designed for a wetter climate and lack large-scale storage.
- Climate change is making droughts more frequent, forcing a rethink of water infrastructure.
- Reservoirs are not a silver bullet; they come with environmental and social costs.
The Franco Legacy: A Double-Edged Sword
The association of Spain's reservoirs with the Franco dictatorship adds a layer of complexity. The regime's aggressive dam-building was part of a broader push for economic development and agricultural expansion. While it brought water to arid regions, it also displaced communities and altered ecosystems.
Today, that legacy is being reevaluated. Some argue that without those reservoirs, Spain would be far more vulnerable to drought. Others point out that the environmental damage was significant and that a more balanced approach is needed. The debate is not just about infrastructure but about how societies adapt to a changing climate.
What Other Countries Are Doing
Across Europe, governments are scrambling to address water scarcity. France has imposed restrictions in dozens of departments, and Germany is grappling with low river levels that disrupt transport and industry. The Netherlands, famous for its water management, is also feeling the pinch.
Some countries are considering new reservoirs, while others focus on demand reduction, leak repairs, and water recycling. The UK, for instance, is investing in mega-reservoirs and water transfer schemes. But these projects take years to complete and face planning hurdles.
| Country | Number of Major Dams | Drought Status (2022) | Key Adaptation Measures |
|---|---|---|---|
| Spain | ~1,200 | Moderate drought | Reservoir storage, desalination |
| UK | ~500 | Severe drought | Hosepipe bans, new reservoirs planned |
| France | ~700 | Severe drought | Water restrictions, recycling |
| Germany | ~300 | Moderate drought | River management, demand reduction |
The Future of Water Infrastructure in Europe
The drought of 2022 may be a turning point. As climate change intensifies, the need for robust water infrastructure becomes undeniable. But the solution is not simply to build more dams. It requires a mix of storage, efficiency, and ecosystem protection. The background to this story is set out in Climate Crisis Drought: Heat Sucks Soils Dry Across Europe. A related thread runs through Climate Crisis Drought: Heat Sucking Soils Dry Across Europe. Earlier coverage in Global Water Crisis: Drought, Rationing, and Dry Rivers shows how the argument developed.
Spain's experience offers lessons—both positive and negative. The country's reservoirs have been crucial for agriculture and urban supply, but they have also caused ecological harm. Northern Europe must find its own path, balancing the need for water security with environmental stewardship.

One thing is clear: the era of taking water for granted is over. The condescension towards Spain's dams has given way to a grudging respect. As the UK and others face their own water crises, they may soon be building reservoirs of their own.
