This dataset is now retired and replaced with the following:

Reservoir Flood Extents - Fluvial Contribution (National) https://environment.data.gov.uk/dataset/db114020-465a-412b-b289-be393d995a75 Reservoir Flood Extents - Wet Day (National) https://environment.data.gov.uk/dataset/d81646cf-37e5-4e71-bbcf-b7d5b9ca3a1c Reservoir Flood Extents - Dry Day (National) https://environment.data.gov.uk/dataset/c66ee97f-49d2-454e-9a19-d48a47bd22ad

This is the simplified version of the outline Reservoir Flood Map Outline (Speed) as shown on the gov.uk Flood Risk website. This is one of 3 available "Risk of Flooding from Reservoirs" Web Mapping Services; Maximum Flood Depth, Maximum Flood Extent, Maximum Flood Speed.

. Simplified in this context refers to the fact that unlike the detailed product, individual reservoir flood map speeds are not shown separately, and one merged outline shows the maximum flood speeds for all reservoir flooding scenarios together.

This is a data layer showing a combined reservoir flood map for 2,092 Large Raised Reservoirs including attributed data. The data shows the maximum speed of flooding 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 (Speed) in its simplified form is referred to externally as Risk of Flooding from Reservoirs – Maximum Flood Speed.

The Reservoir Flood Map Outline (Speed) shows the maximum flood speeds that might be expected 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 flooding would create speeds this high. 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: Only the Maximum extent, velocity and depth categories are available under the standard OGL terms when supplied as a WMS. This excludes the underlying data. Attribution statement: © Environment Agency copyright and/or database right 2019. All rights reserved.

This dataset is refreshed on a weekly basis from the datasets the team works on daily.Last update date: 11 July 2025.National Highways Operational Highway Boundary (RedLine) maps out the land belonging to the highway for the whole Strategic Road Network (SRN). It comprises two layers; one being the an outline and another showing the registration status / category of land of land that makes up the boundary. Due to the process involved in creating junctions with local highway authority (LHA) roads, land in this dataset may represent LHA highway (owned by National Highways but the responsibility of the LHA to maintain). Surplus land or land held for future projects does not form part of this dataset.The highway boundary is derived from:Ordnance Survey Mastermap Topography,HM Land Registry National Polygon Service (National Highway titles only), andplots researched and digitised during the course of the RedLine Boundary Project.The boundary is split into categories describing the decisions made for particular plots of land. These categories are as follows:Auto-RedLine category is for plots created from an automated process using Ordnance Survey MasterMap Topography as a base. Land is not registered under National Highways' name. For example, but not limited to, unregistered ‘ancient’ highway vested in Highways England, or bridge carrying highways over a rail line.NH Title within RedLine category is for plots created from Land Registry Cadastral parcels whose proprietor is National Highways or a predecessor. Land in this category is within the highway boundary (audited) or meets a certain threshold by the algorithm.NH Title outside RedLine category is for plots created in the same way as above but these areas are thought to be outside the highway boundary. Where the Confidence is Low, land in this category is yet to be audited. Where the Confidence is High, land in this category has been reviewed and audited as outside our operational boundary.National Highways (Technician) Data category is for plots created by National Highways, digitised land parcels relating to highway land that is not registered, not yet registered or un-registerable.Road in Tunnel category, created using tunnel outlines from Ordnance Survey MasterMap Topography data. These represent tunnels on Highways England’s network. Land is not registered under National Highways' name, but land above the tunnel may be in National Highways’ title. Please refer to the definitive land ownership records held at HM Land Registry.The process attribute details how the decision was made for the particular plot of land. These are as follows:Automated category denotes data produced by an automated process. These areas are yet to be audited by the company.Audited category denotes data that has been audited by the company.Technician Data (Awaiting Audit) category denotes data that was created by National Highways but is yet to be audited and confirmed as final.The confidence attribute details how confident you can be in the decision. This attribute is derived from both the decisions made during the building of the underlying automated dataset as well as whether the section has been researched and/or audited by National Highways staff. These are as follows:High category denotes land that has a high probability of being within the RedLine boundary. These areas typically are audited or are features that are close to or on the highway.Moderate category denotes land that is likely to be within the highway boundary but is subject to change once the area has been audited.Low category denotes land that is less likely to be within the highway boundary. These plots typically represent Highways England registered land that the automated process has marked as outside the highway boundary.Please note that this dataset is indicative only.

Dies ist die vereinfachte Version der Gliederung Reservoir Flood Map Outline (Tiefe), wie auf der gov.uk Flood Risk Website gezeigt. Dies ist eines von 3 verfügbaren Web-Mapping-Diensten "Überschwemmungsrisiko aus Reservoirs"; Maximale Hochwassertiefe, maximale Hochwasserausdehnung, maximale Hochwassergeschwindigkeit.

Vereinfacht in diesem Zusammenhang bezieht sich auf die Tatsache, dass im Gegensatz zum detaillierten Produkt einzelne Reservoir-Hochwasserkartentiefen nicht separat dargestellt werden, und eine zusammengeführte Gliederung zeigt die maximale Hochwassertiefe für alle Reservoir-Hochwasserszenarien zusammen.

Dies ist eine Datenschicht, die eine kombinierte Reservoir-Hochwasserkarte für 2.092 große erhöhte Reservoirs einschließlich zugeordneter Daten zeigt. Die Daten zeigen die maximale Tiefe der Überschwemmungen, sollten Reservoirs durchbrochen werden, und obwohl die Lage jedes Reservoirs abgeleitet werden kann, werden sie nicht explizit auf den Karten angezeigt. Die Reservoir Flood Map Maximum Flood Outline (Depth) in ihrer vereinfachten Form wird extern als Flooding Risk of Reservoirs – Maximum Flood Depth bezeichnet.

Die Reservoir Flood Map Outline (Depth) zeigt die maximalen Hochwassertiefen, die zu erwarten wären, wenn ein Reservoir ausfallen und das Wasser, das es enthält, freisetzen würde. Da dies eine Vorhersage eines glaubwürdigen Worst-Case-Szenarios ist, ist es unwahrscheinlich, dass eine tatsächliche Überschwemmung so tief wäre. Diese Daten sind nur für die Notfallplanung bestimmt und für groß angelegte Hochwasserrisikobewertungen nicht zuverlässig.

Bitte beachten Sie, dass nur Hochwasserkarten für große Stauseen angezeigt werden. Hochwasserkarten werden nicht für kleinere Reservoirs oder für Reservoirs angezeigt, die nach Beginn der Reservoirkartierung im Frühjahr 2009 in Betrieb genommen wurden.

Hinweishinweis: Nur die Kategorien Maximale Ausdehnung, Geschwindigkeit und Tiefe sind unter den Standard-OGL-Bedingungen verfügbar, wenn sie als WMS geliefert werden. Dies schließt die zugrunde liegenden Daten aus. Erklärung zur Namensnennung: © Copyright und/oder Datenbankrecht der Umweltbehörde 2019. Alle Rechte vorbehalten.
