Drought warning amid prolonged dry weather in Devon, Cornwall, and Isles of Scilly

Environment Agency urges caution following warmest spring on record

The Environment Agency has declared a state of prolonged dry weather for Devon, Cornwall, and the Isles of Scilly following England’s warmest spring on record and multiple summer heatwaves.

This shift recognises significant reductions in rainfall, lowered river flows, high temperatures, and mounting environmental pressures.

Authorities are prepared to address environmental incidents caused by these conditions, balancing water usage and environmental protection.

Joanne Laeger, Environment Planning & Engagement manager at the Environment Agency, highlighted the area's transition into prolonged dry weather status.

She said, “Devon, Cornwall, and the Isles of Scilly is the third Environment Agency area to move into a state of prolonged dry weather this year.

Following the warmest spring on record and the third heatwave of the year, we could see a summer of environmental incidents ranging from fish in distress to algal blooms.

The Environment Agency urges everyone to do their bit and use water more wisely. The more water we use, the less there is available for the environment.

Our climate is changing. We are already seeing wetter winters and hotter, drier summers. In our area, prolonged dry weather is occurring more frequently.”

Despite rainfall early in the year, Devon, Cornwall, and the Isles of Scilly experienced below-average precipitation from March to May.

While rainstorms in June were welcome, they did not offset earlier deficits, resulting in drier-than-normal soils and commonly low river flows.

Private water supplies from boreholes are facing challenges in some locations.

What's Next?

The National Drought Group - comprising the Met Office, government bodies, regulators, water companies, the National Farmers’ Union, Canal & River Trust, anglers, and conservation experts - continues to monitor the situation and is scheduled to convene on 20th July.

In the meantime, the Environment Agency is promoting the Let’s Save Water: Water Efficiency Campaign for England & Wales, which encourages residents to adopt simple water conservation practices.

Suggestions include reducing shower time, repairing home leaks, opting for buckets or watering cans over hosepipes, using a washing-up bowl, and selecting eco settings on appliances.
