Flow Compliance Bands

This is a national picture of flow compliance with the environmental flow indicator shown for Water Framework Directive Cycle 2 river water bodies.
The Environment Flow Indicator (EFI) is used to indicate where abstraction pressures may start to cause undesirable effect on river habitats and species. Non-compliance with the EFI is divided into 3 categories depending on how far below the EFI recent actual flows are. Attribution statement: © Environment Agency copyright and/or database right 2015.
