UK Drought 2024: Five Reservoirs Exceptionally Low 2026

The UK drought has pushed five reservoirs in England and Wales to exceptionally low levels, raising urgent concerns over public water supply as the crisis persists into autumn. With almost three-quarters of England and all of Wales now in drought, the pressure on water resources is unprecedented.

Current Reservoir Levels and Data

According to Environment Agency data from 11 August, five key reservoirs are now classified as "exceptionally low." These include Wimblewall reservoir in Devon, operated by South West Water, which stands at just 46% capacity. Clatworthy in Somerset is at 48%, Hanningfield in Essex at 56%, Clywedog in Powys at 56%, and the Dove group in Derbyshire at 69%.

Across England, total reservoir levels have fallen to 66%, down from 69% the previous week and nearly 14 percentage points below the seasonal average. Of the 32 strategically important reservoirs, only four remain at normal levels: Draycote Water, Bewl, Roadford, and Vyrnwy.

Why Reservoirs Matter for Water Security

Reservoirs are essential for ensuring a reliable water supply, providing drinking water to millions of households and businesses. The current low levels threaten not only domestic use but also agriculture, industry, and firefighting capabilities.

The National Hydrological Monitoring Programme reported that July's aridity was "unprecedented," and below-normal to exceptionally low water flows are expected to persist well into autumn. This cumulative impact, with three droughts in the past five years, signals a "new territory" for water management, according to Alastair Chisholm of Arup.

Key Takeaways for Water Users

• Reservoir levels are critically low, with five at exceptionally low status.
• Total England reservoir capacity is 66%, far below seasonal norms.
• Drought conditions are likely to continue into autumn, increasing supply risks.
• Households and businesses should adopt water-saving measures immediately.
• Government and water companies must invest in long-term resilience.

Expert Insights and Future Outlook

Experts warn that the repeated droughts are straining infrastructure designed for a different climate. Last year, reservoirs in Yorkshire and the Pennines fell below 39% capacity by this time, and the ongoing pattern is concerning.

Water companies are implementing hosepipe bans and urging conservation, but more systemic changes are needed, including investment in desalination, leakage reduction, and reservoir expansion.

FAQ

Conclusion

The UK drought is a stark reminder of climate change's impact on water resources. With five reservoirs exceptionally low and no immediate relief in sight, proactive measures are essential to secure water for the coming months.
