Witham 🌊 Tidal
Witham catchment • Chapel Hill • Lincolnshire • ID: E4403 • Level
This gauge is tidally influenced — levels rise and fall with each tide, so rapid changes here are normal and don't necessarily indicate flooding.
⚙ Tidally influenced - confirmed by cross-correlation with a nearby tide gauge (auto-classifier missed it). Excluded from rising-rivers rankings and the prediction models.

Flood predictions aren't generated for tidal gauges — their levels are driven by the tide, 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.

26 storm overflows are traced upstream of this gauge, the nearest 2.8 km away along the river. 0 report discharging now, 26 report not discharging.

Frequently asked questions

Is the River Witham at Chapel Hill flooding today?

The current level is 0.99m, which is within the typical range of 0.39 to 1.33m. Flooding is unlikely at this level.

Is the river level rising or falling at Chapel Hill?

Based on the most recent readings, the level is currently steady. 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 Witham at Chapel Hill?

The typical range at this station is 0.39m to 1.33m, based on Environment Agency historical data. Levels above 1.33m 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.
