Frequently asked questions

Is the Groundwater Level at Hodcott flooding today?

The current level is 106.28m, which is within the typical range of 104.88 to 117.75m. Flooding is unlikely at this level.

Is the river level rising or falling at Hodcott?

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. 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 Hodcott?

The typical range at this station is 104.88m to 117.75m, based on Environment Agency historical data. Levels above 117.75m 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.
