Full list of latest reservoir levels across England

Reservoir levels in north-east and north-west England are at their lowest on record for this time of year, with some sites at only half their average long-term storage, new figures show.

Haweswater and Thirlmere in Cumbria are at 49% of their typical capacity due to a combination of dry weather and planned maintenance, while the Pennines group of reservoirs is down to 48%.

The Dee system in north Wales, which supplies many areas of the North West of England, has been affected by a lack of rainfall and a planned lowering of water for safety reasons, leaving it at 75% of capacity – a level classed by the Environment Agency as “exceptionally low”.

Storage across England as a whole stood at 77% at the end of May, down from 84% at the end of April and the lowest on record for the time of year – though some sites have reported normal or above normal levels.

Here is a full list of reservoir storage at the end of May 2025.

The figures have been published by the Environment Agency and show the current level as a proportion of the long-term average.
