Risk of Flooding from Reservoirs - Maximum Flood Extent
This is the simplified version of the outline Reservoir Flood Map Outline (Extent) as shown on the Environment Agency website. Simplified in this context refers to the fact that unlike the detailed product, individual reservoir flood map extents are not shown separately, and one merged outline shows the maximum flood extent for all reservoir flooding scenarios together. This is a data layer showing a combined reservoir flood map for 2,092 Large Raised Reservoirs. The data shows the maximum extent of flood should reservoirs be breached, and although the location of each reservoir can be inferred they are not explicitly shown on the maps. The Reservoir Flood Map Maximum Flood Outline (Extent) in its simplified form is referred to externally as Risk of Flooding from Reservoirs – Maximum Flood Extent. The Reservoir Flood Map Outline (Extent) shows the largest area that might be flooded if a reservoir were to fail and release the water it holds. Since this is a prediction of a credible worst case scenario, it’s unlikely that any actual flood would be this large. These data are intended for emergency planning only and are not reliable for large scale flood risk assessments. Please note that only flood maps for large reservoirs are displayed. Flood maps are not displayed for smaller reservoirs or for reservoirs commissioned after reservoir mapping began in spring 2009. Information Warning: The Maximum extent category is available under the standard OGL terms when supplied as a WMS. This excludes the underlying data.
