The Environment Agency has confirmed that all of the South West of England is now in drought following some of the driest conditions in nearly 90 years.

The Agency said that while the area has had some rainfall over the last 2 weeks, this has not been sufficient to compensate for the long dry period in recent months.

Bristol, Somerset, Dorset, south Gloucestershire and parts of Wiltshire (referred to in the Environment Agency as the Wessex area) have all moved to drought status. Earlier this month Devon, Cornwall and the Isles of Scilly were also declared to be in a drought.

The triggers used to confirm the move to drought status for the area include the hydrological position (including rainfall, river flows, groundwater levels, reservoir levels, and the dryness of soils), as well as the impacts these conditions have on the environment and abstractions.

While essential water supplies are safe, Defra and the Environment Agency are urging water companies to continue with their precautionary planning to protect essential supplies in the event of a dry autumn.

In the Wessex area, the effects of drought are resulting in low river flows impacting the environment in and around rivers.

Chris Paul, the Environment Agency’s area drought lead, said:

“Despite some heavy rain over the past 2 weeks, it has not been enough to refill our rivers and aquifers.

“River levels across our Wessex area are exceptionally low - many showing the lowest flows on record. This places incredible strain on local wildlife and this is why we are moving to drought status. We are prioritising our local operations to minimise impacts on the environment.

“Action being taken across the area includes additional monitoring of the effects of the dry weather on rivers and responding to environmental emergencies, such as rescuing stranded fish, wherever possible. We will also be ensuring people and companies who have water abstraction licences only operate within the terms of their licence and taking legal action against those who fail to comply or against anyone who abstracts water without a licence.”

The Environment Agency’s water situation national report for July provides a picture of the rainfall, soil moisture deficit, river flows, groundwater levels and reservoir levels over the last month. The report highlights that it was the driest July across England since 1935, with monthly rainfall totals for the majority of river catchments classed as exceptionally low for the time of year.

There have been 5 consecutive months of below average rainfall across all geographic regions in England and above average temperatures. River flows, groundwater levels and reservoir stocks all decreased during July.

With Wessex now declaring a drought, 11 of the 14 Environment Agency areas in England are now in drought status.
