Identifying risk from reservoir flooding
The Environment Agency is responsible for 2,000 reservoirs in England and Wales and enforces the Reservoirs Act 1975.
However, the safety of reservoirs is the responsibility of the reservoir's owners or operators, although the Environment Agency is responsible for enforcing the safety legislation.
The key roles of the Environment Agency in regards to reservoirs are:
surveillance - maintaining a register of reservoirs for England and Wales
enforcement - achieving compliance with the legislation.
Our key roles for reservoirs
We are responsible for coordinating emergency plans for reservoir flooding and ensuring communities are well prepared. We work with emergency services, reservoir operators and the Environment Agency to achieve this.
The Environment Agency's flood risk maps (opens in a new window) show areas that are potentially at risk from reservoir flooding. The risk of flooding from reservoirs anywhere in the country is dependent on the unlikely but potentially catastrophic failure of dams to reservoirs.
The Environment Agency's reservoir flood risk map should not raise concern, but should make you think what you might do if an emergency did happen and your home or workplace was at risk.
If you have a general enquiry on reservoir safety you can call the Environment Agency on 08708 506 506. You can also email them with reservoir enquiries.
In an emergency you can call their hotline on 0800 80 70 60.
