Classifications data for Northumbria River Basin District
Classification data is a method for distinguishing the environmental condition or "status" of water bodies and putting them into one category or another.
To find out more about classifications, see the current condition and environmental objectives document. An explanation of terms is in the glossary.
You can see the water body and classification data on the river basin management plan map viewer.

| Lake | 9 | 10 | 26 | 45 |
| Coastal | 5 | 1 | 1 | 7 |
| Estuarine | 1 | 0 | 6 | 7 |
| Groundwater | 10 | 0 | 0 | 10 |
| Total | 246 | 13 | 125 | 384 |
Ecological status for surface waters
Table summarises the current ecological status of surface water bodies. Water bodies are classified as being at high, good, moderate, poor or bad ecological status or potential.

Historic classification data
Data is only summarised on these pages for the latest cycle. This is due to lack of comparability because of changes in water bodies and classification approaches. Historic data for previous cycles, as published, is available from the following downloads:
