Frequently asked questions

Is the Groundwater Level at Lower Farringdon flooding today?

The current level is 95.10m, which is within the typical range of 93.72 to 113.45m. Flooding is unlikely at this level.

Is the river level rising or falling at Lower Farringdon?

Based on the most recent readings, the level is currently falling slightly. The chart above shows the last 12 hours of measurements by default (up to 7 days), 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. Only about 9.3mm 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.

What is a normal level for the Groundwater Level at Lower Farringdon?

The typical range at this station is 93.72m to 113.45m, based on Environment Agency historical data. Levels above 113.45m are higher than usually seen and may indicate a flood risk.

How often is this river level data updated?

Readings are supplied by the Environment Agency gauge. FloodRadar checks for updates roughly every 15 minutes; the timestamp above shows how recent the latest available reading is.
