If you plan to abstract or impound water, the Environment Agency may need you to provide flow data with your application. If you want to clarify whether data is needed and what type, you can get advice before you apply for a licence to abstract or impound water.
The flow data normally needed includes:
- flow duration statistics including the mean flow value
- details of how you have produced the flow duration statistics
- flow measurements to validate the flow duration statistics
- hydrographs showing the impact of your proposal
This guidance explains what these terms mean and how you can get the information.
