Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
The current level is 75.97m, which is within the typical range of 63.44 to 89.15m. Flooding is unlikely at this level.
Based on the most recent readings, the level is currently falling slightly. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.
When little or no rain has fallen for a while, a river level gradually drops as the water stored in the ground and soil drains away with nothing to replace it. This is called baseflow recession and is normal in dry spells. Only about 4.2mm of rain has fallen nearby in the last 7 days, so the flow is being sustained mainly by groundwater. A gentle decline like this is expected and is not a sign of a problem — downstream gauges often recede a little faster than headwaters further upstream, and levels recover once rain returns.
The typical range at this station is 63.44m to 89.15m, based on Environment Agency historical data. Levels above 89.15m are higher than usually seen and may indicate a flood risk.
Readings are taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
