Reservoir Flood Extents - Fluvial Contribution (National)

Alternative title(s)

Risk of Flooding from Reservoirs - Flood Extents - Fluvial Contribution

Abstract

This data shows the extent of river flooding added to the reservoir model to determine the impacts of failure on a wet-day. It is not exactly the same as the flooding from rivers shown in the Flood Map for Planning from Rivers and Sea. The fluvial-only extent should only be used to see the impact the reservoir flooding has. Flood extents are not included for smaller reservoirs or for reservoirs commissioned after the reservoir modelling programme began in October 2016.

Quality and validity

Lineage

In 2010 the Environment Agency published the National Reservoir Inundation Maps. The maps provide an indication of the flooding that would occur if a failure of a reservoir embankment or structure led to an uncontrolled release of water. The Environment Agency has reviewed, updated and improved the reservoir flood maps as part of the Reservoir Flood Mapping Project. The maps show the extent of flooding for all large-raised reservoirs that were in operation in October 2016. New reservoirs after that date will be modelled under the next review of the flood maps, which is due in by 2025.
