Spatial inventory of UK waterbodies

The dataset is the lake polygons from the UK Lakes Portal (https://uklakes.ceh.ac.uk/), originally based on OS PANORAMA but this dataset includes data from a number of sources. It has a basic set of attributes including the water body ID (WBID) as well as the computed area and perimeter of each lake. The WBID is commonly used across research institutions and is the same ID as used on the UK Lakes Portal, where more information can be found on each lake in this dataset. This is v3.6, which follow

Useful for

Use cases llm-inferred
Look up WBIDs and lake polygon areas for standing-water screening in flood risk or drainage assessments · Map standing waters for BNG or habitat baseline reports using OSGB lake polygons · Identify the WBID for a lake, then link to UK Lakes Portal data for ecological or water quality context

Limitations

Constraints llm-inferred
Lake polygons and basic attributes only; no water level, flow or quality data in this dataset · Polygon outlines were revised across versions, so the v3.6 geometry may differ from older lake outlines · Citation and Ordnance Survey / Crown copyright attribution are required when used
