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 caused 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.
Check our live flood warnings map for warnings in force across Wales.
