Description: Groundwater waterbodies created for the Water Framework Directive (2000/60/EC). This feature class was created using the OS Boundary Line 'High Water Mark' dataset and internal boundaries from SEPA's original 50K Groundwater WBs. The original data was created for the Water Framework Directive (2000/60/EC). More detail on the methods used to create the dataset are available in this report: Scotland's aquifers and groundwater bodies - NERC Open Research Archive (http://nora.nerc.ac.uk/id/eprint/511413/). The groundwater bodies have been created at two levels, the superficial groundwater bodies are those nearest to the surface and these are attributed as Horizon 1 whereas the bedrock groundwater bodies are attributed as Horizon 2. Each horizon is published as a separate layer to enable the correct ordering of the water bodies. Dataset includes the most recent overall classification information.
Description: This feature class was created using the OS boundary line High Water dataset, OS Open Map Local dataset and UKHO Open Data 3 nautical mile limit. The original data was created for the Water Framework Directive (2000/60/EC). Article 2, clause 6 of the WFD defines Transitional waterbodies as ‘…bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but are substantially influenced by freshwater flows’. These are also referred to as estuaries. Derived from the OS Boundary Line High Water line dataset and Scottish Environment Protection Agency estuarine boundaries defined for the Urban Waste Water Treatment Directive (UWWTD) with the addition of Loch Etive. The dataset includes the overall classification values from the most recent year, usually the previous year.
Description: This feature class was created using the OS boundary line High Water dataset, OS Open Map Local dataset and UKHO Open Data 3 nautical mile limit. The original data was created for the Water Framework Directive (2000/60/EC). Article 2, clause 7 of the WFD defines coastal waterbodies as ‘…a surface water on the landward side of a line, every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured, extending where appropriate up to the outer limit of transitional waters’. Due to the large number of islands in Scotland, coastal waters were defined by territorial waters 3 nautical miles from the Mean High Water coastline covering all water within the 3 nautical mile territorial limit. The dataset includes the overall classification values from the most recent year, usually the previous year.
Description: This dataset contains baseline loch water bodies which were created for the purposes of the Water Framework Directive (2000/60/EC) . The dataset is made up of the following categories of features:Baseline Lochs - lochs with a surface area greater than or equal to 0.5 km².The dataset includes the overall classification values from the most recent year, usually the previous year.
Description: River waterbodies created for the Water Framework Directive (2000/60/EC) . The dataset is made up of the following categories of features:1. River, also know as baseline river water bodies. These represent rivers where the mouth has a catchment area greater than 10 km². 2. Canal. Canal water bodies do not have associated catchment boundaries. Small river water bodies and loch centrelines are excluded from this dataset as no classification information is available for these features. The dataset includes the overall classification values from the most recent year, usually the previous year.

Copyright Text: The river water bodies are derived from the Ordnance Survey Master Map Water Network Layer, for which SEPA has a derived data exemption to publish these features as open data.
Description: Natural and artificial obstacles to migratory fish, including salmonids, eels and lamprey in Scotland. There are also several obstacles recorded in the English part of the Tweed and other cross-border catchments. This dataset is used to calculate the fish barrier classification status for all baseline river and loch water bodies as one of the parameters required for the Water Framework Directive (WFD) classification system.

Description: These are the Water Framework Directive (WFD) River Basin Districts (RBDs) for Scotland. River basin plans and advisory groups are required by sections 15 and 17 of the Water Environment and Water Services (Scotland) Act 2003. They help SEPA with WFD river basin management plan production. The RBDs are based on river catchment boundaries and were defined after consultation with Stakeholders. RBDs are the largest reporting unit under the WFD.
Description: These are the Water Framework Directive (WFD) Sub Basin Districts (SBDs) for Scotland. Sub basin plans and advisory groups are required by sections 15 and 17 of the Water Environment and Water Services (Scotland) Act 2003. They help SEPA with WFD river basin management plan production. The advisory groups are based on river catchment boundaries and were defined after consultation with Stakeholders. There is a many to one relationship between SBDs and River Basin Districts (RBDs).
Description: A polygon dataset showing the area of land draining directly to each baseline surface water body (rivers with a catchment >= 10 km² & lochs with a surface area >= 0.5 Ha), this is known as the water body intercatchment. The catchment area upstream of the upper end of each water body is excluded from the polygon, except in headwater catchments. The catchment polygons are mutually exclusive and cannot overlap.
Description: Catchments for all freshwater surface water bodies are required for a number of WFD related projects, including an assessment of diffuse pollution to each waterbody and the assignment of existing monitoring points to water bodies. The nested catchments were created and quality checked by SEPA. Catchments are available for both baseline surface water bodies (rivers with a catchment >= 10 km² & lochs with a surface area >= 0.5 km²) and small water bodies. The catchments overlap in all cases except where a single water body drains directly to the coast and not into a downstream freshwater water body.
Description: A polygon dataset showing the area of land draining directly to each confluence point on the baseline river network (1:50,000), i.e. where two or more rivers, each with a catchment area greater than 10 km², meet. Created as part of the work undertaken to generate the WFD river typology dataset. The catchment area upstream of the next confluence is excluded from the polygon. The catchment polygons are mutually exclusive and cannot overlap.
Description: Catchments generated from each confluence point on the baseline river network, i.e. where two or more rivers, each with a catchment area greater than 10 km², meet. Derived from the work undertaken to generate the WFD river typology dataset. This dataset contains overlapping 'nested' catchments.
Description: The main river and coastal catchments dataset contains the polygons representing SEPA's principle management catchments. The main river catchments are each greater than 100 km². There is one coastal catchment per CEH hydrometric area. The dataset also contains estuary boundaries defined under the Urban Waste Water Treatment Directive. Sea areas are based on National Grid 100K squares. Catchment, estuary and sea area numbers are used as components of the SEPA hydro code.
Description: Background to the Water Environment FundThe Water Environment Fund is made available by Scottish Government and administered by SEPA to fund projects to help restore the river environment across Scotland by improving the physical condition of rivers and easing barriers to fish migration. SEPA works in partnership with local authorities, land and structure owners, fishery trusts, conservation bodies and other partners to deliver an annual programme of projects. WEF physical condition projects repair damaged urban rivers, targeting socially deprived urban areas. They bring environmental benefits including restoration of natural form and processes and enhancement of biodiversity and habitats, and also benefit the communities that live there, by creating accessible green river corridors, improving wellbeing, helping rivers contain flood waters and improving climate resilience.WEF fish barrier easement projects increase the amount of habitat accessible to Scotland’s native migratory fish by removing and easing historical barriers to migration such as redundant weirs. This helps to protect and improve endangered fish populations, restore the natural environment and create new opportunities for angling, tourism and recreation. Details regarding the layer and caveatsThe layer identifies by a point, locations of future, current and complete physical condition and fish barrier easement projects.• The ‘future opportunities’ given here are early-stage potential opportunities identified for fish barrier easement and physical condition projects, which will be subject to further work to determine their feasibility and therefore are not all certain to progress to project delivery.• Physical condition projects are identified using a single grid reference however by their nature apply to a river reach (or reaches).• Data is a snapshot as of December 2022 and subject to future updates.• Due to the impacts of the cyber attack on SEPA systems our records may be incomplete and / or contain errors which we will endeavour to resolve.
