Expert comments: NW droughts and UK reservoirs
30 May 2025

Drought has been declared in the by the Environment Agency, as the it was speeding up plans to build two new reservoirs in Cambridgshire and Lincolnshire.
Professor Richard Allan, Professor of Climate Science, 伊人直播app, said:
“The lack of rainfall across the UK in spring 2025 constituted a meteorological drought and this quickly depleted the soil’s moisture leading to concerns over agricultural drought. Lowering river and reservoir levels are a concern for the northwest of the UK as further dry spells could threaten the supply of water as part of a hydrological drought. Of less concern are regions of copious ground water like the chalky catchments in the southeast of England which enter but also leave drought conditions more slowly than other regions of the UK.
“Droughts are expected to onset more rapidly and become more intense as the planet warms since the atmosphere’s thirst for water grows. A warming climate means moisture is more readily sapped from one region and blown into storm systems elsewhere, intensifying both wet and dry weather extremes with wilder swings between them. The only way to limit the increasing severity of wet and dry extremes is to rapidly cut greenhouse gas emissions across all sectors of society.”
Professor Hannah Cloke, Professor of Hydrology at the 伊人直播app, said:
“We need a complete overhaul of the way we use water, to plug leaks, cut down on waste and store water where it falls as rain. It would be better to make more difficult decisions around the regulation of new building, as well as retrofitting older homes and businesses, to cut waste and recycle water where it is used, rather than pumping water across huge distances.
Dr Jess Neumann, associate professor of hydrology, 伊人直播app:
"The north-west of England has seen an exceptionally dry spring - the driest in nearly 100 years. This lack of rainfall has led to low water levels in reservoirs and rivers. The north-west of the country is reliant on reservoirs to source around two-thirds of its water supply.
"Droughts are caused by a lack of rainfall and although they are often associated with hot weather during summer months, droughts can occur at any time of year and persist for months, or even years. The 2025 drought is serious - reservoir levels are well-below what they should be at this time of year. This raises important questions about how water will be managed this summer, but also going forward long-term. Water is becoming a scarce resource and the UK supply is under significant stress.
"Water companies are already implementing Drought Action Plans, but as individuals, we need to be mindful of our water use. Freshwater is not a finite resource and unless the UK takes action in the near future, one day some regions could find taps running dry. Be mindful of how much water you use - switch to a watering can for your garden now; capture and re-use rainwater with water butts, buckets and tubs; take short showers; turn the tap off whilst brushing teeth; capture cold water in a pan whilst waiting for the hot water to flow and use it to water your plants. Small actions by lots of people make the difference.
"A drought that takes hold of the environment spells bad news. Droughts can create shortages of food as crops fail, can lead to higher food prices rise, and there can be public health implications and knock-on impacts to the economy, and for wildlife."
