What this reading tells you

It is the latest value published for this monitoring instrument at the stated observation time. The unit mASD is retained from the Environment Agency measure record.

This page does not currently have an approved typical range or warning threshold for this measure, so it does not label the reading as high, normal or low.

Need a current safety answer?

A gauge reading is not a flood warning or a property-risk assessment. Use the official warning service for current alerts and follow emergency-service advice.
