This is a web tool for displaying water resources and drought information based on:

• River flows from the National River Flow Archive (updated monthly)* and Environment Agency (updated daily).
• Rainfall from the Met Office (provided on a grid, and aggregated up to gauging station catchments and river basins) (updated monthly).
• Soil moisture from UK CEH's COSMOS-UK soil moisture network (updated daily).
• Groundwater levels from the British Geological Survey* (updated monthly).

What's new

• Colour changer — toggle between rainbow and red–blue.
• Toggle size button (in top bar) to enable full or half width maps and graphs.
• Station lists for each dataset ( ), so can search for station, view the graph and download the standardised indices csv data.
• Rainfall SPI hydrological units areas and groups swap depending on zoom level, including raw monthly data.
• Graphs for rainfall SPI grids (click on a grid square).
• View entire time-series for standardised indices (click the All button from # of years). Rainfall SPI hydrological units data available from 1862.

More information

Please note that:

• Near real-time river flows are only available for England — these come from the Environment Agency Hydrology data service.
• River flow data for the last few days is often not available via the Environment Agency Hydrology data service — step back a few days to see the most recent data, or switch to monthly data.
• Dotted lines on the river flow graphs mean data remain unchecked (by the Environment Agency) and may be erroneous.
• River flow data for Scotland, Wales and Northern Ireland, rainfall and groundwater data and the standardised indices are currently only available to the end of the previous month.

View a video of how to use the UK Water Resources Portal and go to the About page for more information about the portal, including the datasets and methods used.

For more information on major flood and drought events see the occasional reports of the National Hydrological Monitoring Programme.
