Risk of Flooding from Reservoirs

  • English

  • All

NRW is responsible for assuring the safety of the Welsh reservoirs by enforcing the Reservoirs Act 1975. Simplified inundation mapping was carried out nationally by the Environment Agency to provide a baseline assessment of all reservoirs falling within the Act. This work is now carried out by Natural Resources Wales (NRW). Reservoirs Flood Maps – Spatial Data are referred to externally as Risk of Flooding from Reservoirs.

Lineage

The detailed outputs show the potential flood risk if reservoirs were breached. The models were created at various resolutions ranging from 10 metre cells through to 50 metre squares for locations furthest away from the breach. These files are not available as a single, discrete file since each reservoir has been modelled individually. It should be noted that these model outputs are for emergency planning purposes and are not intended to reflect the most detailed flood extents. As such these data show the absolute maximum flood where there is likely to be an impact.
