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
  • provisionally from spring 2009, ensuring flood plans are produced for specified reservoirs

Managing large, raised reservoirs to reduce flood risk is very important. Ultimately this responsibility for safe management remains with the reservoir owners but the Environment Agency have to enforce that responsibility.

The Environment Agency also maintain a register of all large, raised reservoirs and the information it contains is available to the public. You can find a link to more information on their website in the related links section.
