You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
Beta. You'll be notified when a flood wave detected at an upstream gauge is forecast to reach this station, with an estimated arrival time. Accuracy improves as we verify more waves.
You'll be notified when a new storm-overflow (sewage) discharge starts within ~3 km of this gauge, based on the water companies' near-real-time feeds.

Experimental model fusing soil moisture, river flow, groundwater and catchment

River Flow
90 days
Daily mean discharge (m³/s) with the daily min–max band, from the EA Hydrology API. Flow is the volume of water passing the gauge — often a more direct flood signal than level.

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.
15 storm overflows are traced upstream of this gauge, the nearest 6.2 km away along the river. 0 report discharging now, 14 report not discharging, and for 1 the monitor is offline or has not reported, so their status is not known.

3 other overflows within 6 km are downstream of this gauge or on another branch of the river network, so they are 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 →

Flood history near this gauge
Official Environment Agency warnings issued since 2013 for the 3 flood
areas linked to this gauge (nearest 4.2 km away).
Warnings apply to a whole flood area, not necessarily this exact spot. Years before 2006 aren't covered by the EA's historic record.

🌊 Mixed responseA balance of quick runoff and slower groundwater baseflow.
Your catchment is all the land that drains rainfall into the river above this gauge. Its character — how
steep, wet, wooded, urban or chalky that land is — decides how fast rain here turns into a rising river. A steep, bare or clay
catchment is “flashy” (rises and falls quickly, floods easily); a flat, chalk or well-wooded one is
slow and steady. The tiles below put numbers to that; the flow-duration curve reads left-to-right
from the river’s typical high flows (Q5) down to its low flows (Q95) — a steep curve means a flashy river.

More detail
The catchment
Rising on the Cheviot granite. Mixed geology (Cheviot igneous rock, sandstone etc). No known catchment changes.
The station
Five (crossed) path ultrasonic gauge in a trapezoidal channel, designed to measure full range of flows. River is deep and slow-flowing at Heaton Mill. Previously station number 21806.
How it measures flow
Well performing crossed-path multi-path ultrasonic gauge. Pre 2009 peaks were not recorded accurately above 150 cumecs due to range cap in the gauge configuration. A peak flow rating derived from ultrasonic measurements and confirmed by check gaugings is available.
Flow regime
Considerable spray irrigation abstractions during the summer, but unlikely to affect high flows.
The flow record
Ultrasonic gauge missed peak flows in Sep 2008, July 2009 and March 2010 due to limitation set in gauge configuration, these peaks are estimated from the rating. All missing data periods in daily flows are due to ultrasonic configuration issues. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Till at Heaton Mill flooding today?
The current level is 0.22m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Heaton Mill?
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.
What is a normal level for the River Till at Heaton Mill?
The typical range at this station is 0.24m to 1.03m, based on Environment Agency historical data. Levels above 1.03m 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.
