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.
