How to interpret river measurements

A monitoring station records conditions at a particular location. Water level measurements can use different reference points, so readings from separate gauges are not always directly comparable. Check the measurement type, unit, reference level and recording time before interpreting the figures. Measurements from the same gauge can help show how conditions have changed. Published flood warnings and alerts provide separate information about flood risk. Neither a river reading nor a nearby warning establishes why water is collecting at an individual property.
