How often this river runs high

In a typical year this gauge reaches its typical high of 1.74 m on about 50 days. This year so far: 31 days.

2026 31 days, 4 of them high · 4 high so far
2025 34 days
2024 115 days, 13 of them high · 13 high
2023 2 days
2022 2 days patchy data

Counted from each day's highest reading. Days with missing or implausible readings are left out, so a year marked patchy may have run high more often than shown. The darker part is days above 2.12 m, the level this gauge tops only a few days a year.

Frequently asked questions

Is the Rive Ditch at West Byfleet Bridge flooding today?

The current level is 1.48m, which is within the typical range of 1.32 to 1.74m. Flooding is unlikely at this level.

Is the river level rising or falling at West Byfleet Bridge?

Based on the most recent readings, the level is currently falling. 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 Rive Ditch at West Byfleet Bridge?

The typical range at this station is 1.32m to 1.74m, based on Environment Agency historical data. Levels above 1.74m 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.
