Frequently asked questions

Is TREWS WEIR flooding today?

The latest recorded level is 2.70m. Compare it with the recent history on the chart above to judge whether levels are unusually high.

Is the river level rising or falling at TREWS WEIR?

Based on the most recent readings, the level is currently falling. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.

Why is the level slowly falling?

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. 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.

How often is this river level data updated?

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.
