Flood predictions aren't generated for lock / structure gauges — their levels are driven by gate operation, not by catchment rainfall, so the forecast models would have no skill here.

💧 Storm overflows upstream of this gauge

Storm overflows whose water reaches this gauge on the mapped river network, nearest first by distance along the river. The status is each water company's monitor: it says whether an overflow is discharging, not how much or what it contains.

31 storm overflows are traced upstream of this gauge, the nearest 3.6 km away along the river. 0 report discharging now, 30 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

1 other overflow within 6 km is downstream of this gauge or on another branch of the river network, so it is not listed.

These are the water companies' monitor statuses; a spill does not by itself explain a change in the gauge level. River connections and distances are traced on OS Open Rivers (edition 2026-04), which leaves out many small channels. Explore the sewage map →

How often this river runs high

In a typical year this gauge reaches its typical high of 0.23 m on about 16 days. This year so far: 1 day.

2026 1 day so far
2025 0 days patchy data
2024 3 days

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.

Frequently asked questions

Is the River Thames at Godstow Lock flooding today?

The current level is -0.07m, which is below the typical range. Flooding is very unlikely at this level.

Is the river level rising or falling at Godstow Lock?

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 River Thames at Godstow Lock?

The typical range at this station is 0.05m to 0.23m, based on Environment Agency historical data. Levels above 0.23m 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.
