Do large dams still make sense on the island, and how can water resources be secured?
The usefulness of large dams in Crete is questionable
Crete faces some tough obstacles when it comes to managing its water. The island’s limited geography, island quirks, and climate all play a part.
It’s dry and warm here, with tricky landforms and geology that complicate water availability. All of this has always made water management, well, a headache—especially now, with climate change speeding things up.
Changing Climate and Its Effect on Planning
Plans made years ago for water just don’t hold up anymore. Climate shifts and new hydrological data keep throwing wrenches into the works.
It’s harder to predict rainfall, and that means securing enough water for drinking and other needs gets dicey. Officials say year-to-year changes now mess up older plans, and weird weather events keep popping up, forcing constant updates in how water gets managed.
Decreased Rainfall Trends
Rainfall’s down—a lot. Crete’s heading into its fourth dry year in a row.
This puts more pressure on water supplies and raises the risk of shortages. Less rain hits reservoirs, groundwater, and especially agriculture right where it hurts.
Cost and Efficiency of Water Infrastructure
Big money—over 100 million euros—is earmarked for new dams and reservoirs. But is building more dams really the answer?
These pricey projects might not keep up with the complexity of water scarcity, especially as the climate keeps shifting. Honestly, it’s starting to look like smarter water use, conservation, and new tech could do more good than just pouring concrete everywhere.

Recommendations for Updated Approaches
Water management has to stay nimble and lean on the latest data—like, from the last three to five years, not decades ago. New strategies should:
- Prioritise sustainable and adaptive water use
- Reduce dependence on large and costly infrastructure
- Incorporate short-term interventions alongside long-term planning
- Account for unpredictable weather and extreme events
- Enhance monitoring and data collection for better decision-making
Balancing supply and demand—while respecting environmental limits—matters most. Water-saving tech, reusing water, better irrigation, and protecting natural systems sound like the way forward.
- Long-standing drought and dry conditions worsen due to climate shifts.
- Traditional planning models based on old data now fail to ensure water security.
- Large infrastructure projects are costly and may not be fully aligned with current needs.
- A shift towards adaptive, data-driven, and less invasive water management is essential.
Water Supply Challenges on Crete
Crete’s water supply problems have only gotten worse. The infrastructure is old and not exactly in great shape.
Pipes leak, cisterns crack, and a lot of water just disappears. Add less rain and more demand, and you’ve got a recipe for trouble.
The Aposelemis Dam is the main reservoir for Heraklion and Agios Nikolaos. But it’s running low, thanks to drought and all that neglected infrastructure.
Fixing leaks and updating pipelines isn’t optional anymore—it’s urgent.
Causes and Consequences of Water Issues
Crete’s water headaches mirror what’s happening across the Mediterranean. Climate’s less predictable, while people (and tourists) use more water than ever.
Tourism really amps up demand, putting locals and visitors in competition for the same water. Over time, old irrigation canals and reservoirs got ignored, and now a lot of those systems just don’t work. When you mix in less rainfall, things get pretty rough.
Attempts at Sustainable Water Use
Some communities are trying out sustainable water management and tech. Smart irrigation systems, for example, use internet controls to monitor soil and weather, only watering when it’s actually needed.
One small village in southwest Crete is testing this approach, combining modern tech and strong local involvement. They track their water use closely and share their results, learning fast without waiting for red tape.
Key Measures for Improvement
Here’s what needs to happen to fix Crete’s water supply:
- Repair leaks in all pipelines using durable materials and proper underground installation to prevent future damage.
- Update cisterns to ensure they hold water safely and prevent seepage.
- Implement smart irrigation systems that deliver exact water amounts, saving resources and protecting plants.
- Encourage local management to speed up decisions and allow tailored solutions for each area.
- Maintain infrastructure regularly to avoid degradation seen in past decades.
Getting this right means everyone—experts, authorities, residents—needs to pitch in. It’ll take some upfront investment and ongoing effort, but the payoff is a water system that can handle dry spells and growing demand.
An Example of Local Effort
One valley village is leading the way here. Without a big bureaucracy, they can move fast and mix tradition with new tech to keep their water supply steady.
They keep open records of what’s working and what’s not, so others can learn too. It’s not perfect, but these small steps could teach the rest of Crete a thing or two.
Importance of Water Conservation on Crete
Saving water on Crete isn’t just smart—it’s vital. Without better water capture and careful use, shortages are pretty much guaranteed, and that hits agriculture, daily life, and tourism.
Some practices that help:
- Fixing all known leaks to stop waste.
- Using drip irrigation or timers for gardens and farms.
- Avoiding unnecessary watering during rainy days or cooler weather.
- Educating communities about saving water and why it is important.
None of these are magic bullets, but together, they stretch what little water’s left.

Potamon Dam: Construction Begins to Supply Rethymno and Mylopotamos
After a long wait, construction finally started on the water treatment plant at Potamon Dam in Amari. This facility will deliver clean drinking water to Rethymno and Mylopotamos, reaching more than 100,000 people.
The contract for the “Water Treatment Installation Utilisation” was signed last December at a pretty official event, with government bigwigs present. By early August, crews were on-site, and the Development Organisation of Crete came for an inspection.
The contractor consortium—THALIS ES SA, TERNA SA, and KONSTANTINIDIS SA—got their final project design approved. Now, they’ll update environmental impact assessments and tweak plans as needed.
This project matters a lot for Rethymno, especially up north where water demand keeps climbing. The new plant aims to meet both today’s needs and what’s expected over the next 20 years.
Getting to this point wasn’t easy. Back in 2019, the Region of Crete and the Development Organisation agreed to use Potamon Dam water, but technical and administrative snags dragged things out for years.
Finally, construction kicked off—a real turning point after all those setbacks. The water treatment plant will sit on about 48 acres in Loutraki, near Giannoudi and Prasies. They bought the land way back in 2007, so this has been brewing for a while.
Some quick facts:
- Capacity: Will supply over 100,000 residents in Rethymno and Mylopotamos.
- Timeline: Construction started August 2025 after years of planning.
- Contractors: Consortium of experienced companies hold the contract.
- Environmental Measures: Updates will keep things up to standard.
- Location: Site was specifically purchased for this.
This initiative ties in with national regional development plans and had a big government presence at launch. Making sure Rethymno and Mylopotamos have reliable water is crucial for economic growth and for people’s well-being.

Sfendyli: The Village Lost to Quench Crete’s Thirst – Residents Return to the Ruins
Sfendyli used to be a small, tight-knit village tucked away in eastern Crete. About ten years back, the place disappeared beneath the waters of the Aposelemi dam.
This dam was built to bring water to almost 40% of Crete’s people. Sure, it solved a lot of water problems for the island, but it also meant the villagers had to leave everything behind.
Even after all this time, the old residents can’t shake their connection to Sfendyli. For the past two years, they’ve been meeting every Sunday at a new church right across from the ruins.
They go back, stare out at the flooded land, and trade memories—trying to keep the spirit of their vanished village alive. It’s a ritual, almost stubborn, but who could blame them?
The villagers talk a lot about what they lost and what they got in return. On one hand, the dam was supposed to help everyone on Crete get water.
On the other, most folks say the compensation didn’t really cover their losses. If you only owned a house and a little land, the payout hardly stretched far enough to start over.

People sometimes call Sfendyli “Crete’s Atlantis.” It’s a dramatic nickname, but it fits—the artificial lake swallowed up most of the village, leaving only a few rooftops peeking out when the water’s low.
The place is changed for good. Fields and houses are somewhere under that calm surface, probably never to return.
The story of Sfendyli has traveled far beyond Crete. There’s even a documentary—Sfendyli: When Water Uproots You—that came out for the tenth anniversary of the flood.
It’s full of interviews and raw moments, following the people as they wrestle with losing their home. The film picked up some awards and played in Heraklion, with villagers and filmmakers showing up to watch together.
If you’re curious, there’s a deeper dive in this report on the village that sacrificed itself. It’s a story that sticks with you, honestly.
