About river levels online

We publish the information about river levels so people living in flood risk areas are better informed and can decide what actions to take as the water levels change.

Anglers and boaters will also be able to use this information to check the water levels before they set off.

Read through our help guide to learn more about our river level online map, how to use its features, where our data comes from and how we use it. Please contact us if you need any information.

Please note

We gather river level data to help us in our role of protecting people and properties from flooding.

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 we make every effort to ensure the accuracy of the information provided, neither Natural Resources Wales, nor its employees or agents can be held responsible for any inaccuracies or omissions, whether cause by negligence or otherwise.

River levels displayed are only an indication of local conditions. This service should not be used as a replacement for the Flood Warning Service.
