River level data is gathered by the Environment Agency to help it fulfil its statutory duties. We publish it online because we recognise that this information may also be useful for others, but we have always made it clear that we cannot guarantee its availability.

There may be occasions when data will not have been collected from a gauging station, therefore results will not appear until the next data collection.

Whilst every effort has been made to ensure the accuracy of the information provided, neither Environment Agency, nor its employees or agents can be held responsible for any inaccuracies or omissions, whether caused by negligence or otherwise.

River levels displayed are only an indication of local conditions.  `Flooding is possible` is an indication of when river levels are high but does not replace our flood warning service.  Please visit the Flood Warning pages to check for warnings in force.

`Typical range` gives an indication of the usual range of water levels throughout the year.  Drought or other water management measures may be in place or issued when water levels are within the typical zone.  Please check our website for the latest information on water resources in your area and whether any restrictions are in place.

We are interested in hearing about how you use this site and any ideas you have which could improve it. Please use to let us know what you think.
