A continuous centreline network of rivers, canals and field drains for Great Britain. The Centre for Ecology & Hydrology’s 1:50,000 watercourse network was derived from Ordnance Survey 1:50,000 maps and was the first continuous digital river network to be produced for Great Britain.

The 1:50,000 watercourses has been used to define flow paths in CEH's Integrated Hydrological Digital Terrain Model (IHDTM), which in turn is used to define drainage paths in the Flood Estimation Handbook CD-ROM.

The British Oceanographic Data Centre (BODC) make quality-controlled National Tidal & Sea Level Facility (NTSLF) data series available online as soon as they are processed for sites around the whole UK.

The UK National Tide Gauge Network was set up as a result of severe flooding along the east coast of England in 1953.

This archive is a unique collation of the Environment Agency's water temperature data from more than 30,000 sites across England & Wales. The archive contains water temperature data (up to 2007) and site metadata.

SEPA monitors water level at 392 sites throughout Scotland. The portal provides level data for the last few days for 335 of these stations.

Most of the stations are sited on rivers; however data from several tide and loch level recorders are also displayed.
