Frequently asked questions

Is the River Ingrebourne at Harold Park flooding today?

The current level is 0.96m, which is within the typical range of -0.24 to 2.20m. Flooding is unlikely at this level.

Is the river level rising or falling at Harold Park?

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. Only about 0.5mm 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 River Ingrebourne at Harold Park?

The typical range at this station is -0.24m to 2.20m, based on Environment Agency historical data. Levels above 2.20m are higher than usually seen and may indicate a flood risk.

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.
