Classifications data for Essex South Management Catchment

Classification data is a method for distinguishing the environmental condition or "status" of water bodies and putting them into one category or another.

Find out more information on classifications in the Current condition and environmental objectives document.

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.
