UK Faces Record Low Reservoir Levels Amid Prolonged Drought

Core Event: “Exceptionally Low” Reservoir Status Across England and Wales
On August 11, Environment Agency monitoring identified five key reservoirs as “exceptionally low.” Wimbleball (South West Water) was at 46 % capacity, Clatworthy (Somerset) at 48 %, Hanningfield (Essex) and Clywedog (Powys) each at 56 %, and the Dove group (Derbyshire) at 69 %. England’s overall reservoir storage fell to 66 %, down from 69 % the previous week and about 14 percentage points below the seasonal average. Only four of the 32 strategically important reservoirs remained at normal levels.
Background & Context
The United Kingdom has endured back-to-back heatwaves this summer, leaving almost three-quarters of England and all of Wales officially in drought. The National Drought Group reports 71.3 % of England in drought and a “prolonged dry weather” status for the North East and Yorkshire. The last nationwide water-cutoff occurred during the 1976 heatwave; today the system relies on water-transfer infrastructure rather than new storage. No major reservoir has been built in the UK since 1992, and water loss through leaky pipes is estimated at 2.87 billion litres per day.
Data & Statistics
- Reservoir capacities (exceptionally low): Wimbleball 46 %, Clatworthy 48 %, Hanningfield 56 %, Clywedog 56 %, Dove 69 %.
- National storage: England 66 % (current), 69 % (last week).
- Hosepipe bans: Approximately 27 million people under bans.
- Leakage: 2.87 billion litres lost daily.
- Future storage projects: Two reservoirs ordered for East Anglia (ready 2036) and Lincolnshire (ready 2040); seven additional large reservoirs planned by 2050, projected to meet only 30-40 % of demand.
Official Statements & Responses
The Environment Agency warned that July’s “unprecedented” aridity will likely persist into autumn, with “further deterioration” possible. Helen Wakeham, director of water at the Environment Agency, said water use “exceeds what nature can replenish” and urged public conservation.
Alastley Chisholm, lead for water policy at Arup, warned that a dry winter would be “very concerning for the government.”
An Ofwat spokesperson highlighted a £2 billion investment programme covering 30 large-scale projects, including nine new reservoirs, stating: “We are taking bold and comprehensive action to secure our water supply for future generations.”
Criticism & Opposition
Greenpeace UK noted that leaking infrastructure wastes far more water than hosepipe bans save, calling for accelerated pipe-replacement programmes. WildFish warned that Southern Water’s application to abstract additional water from the River Test could jeopardise the river’s ecology.
Professor Kevin Grecksch of the University of Oxford criticised water companies for “sleepwalking” into the crisis and said Ofwat has failed to incentivise leakage reduction.
On-the-Ground Reports
Farmers across the drought-hit regions reported poorer yields, livestock forced onto winter feed, and fields turning brown. One farmer described rice plants “already turning red and scorching,” fearing crop failure without timely water.
Conflicting Reports & Gaps
The discrepancy reflects differing reference dates and underscores a lack of a single, up-to-date national metric.

What’s Next
The two newly ordered reservoirs will not become operational until 2036 (East Anglia) and 2040 (Lincolnshire). Seven additional large reservoirs are slated for construction by 2050, but analysts estimate they will satisfy only a fraction of projected demand. In the short term, water companies are seeking extra river abstractions, and regulators are urging accelerated leakage-reduction targets to mitigate the immediate shortfall.
