Quick pick:
You'll be notified when this gauge is rising more than 0.10 m/hr — a sign of rapidly increasing water levels.
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.

Nimbus beta
Experimental model fusing soil moisture, river flow, groundwater and catchment
character. The shaded band is its 10–90% range, widened so that about 80% of recent outcomes fall inside it.
Under evaluation — not yet promoted, so treat as a second opinion. The nearest rain gauge has sent no readings in the last day, so Nimbus has no recent measured rain to work from here.
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.
1 storm overflow is traced upstream of this gauge, the nearest 9.6 km away along the river. 0 report discharging now, 1 reports not discharging.

2 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 →

The darker part is days above 1.12 m, the level this gauge tops only a few days a year.
Flood history near this gauge
Official Environment Agency warnings issued since 2012 for the 2 flood
areas linked to this gauge (nearest 7.4 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.

🌊 Fairly flashyResponds fairly quickly to rain, with moderate baseflow between events.
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.

Low flow gauge with flat-V weir in a rural catchment.
More detail
The catchment
Low-lying, rural catchment draining from west of the Yorkshire Wolds.
The station
Flat-V weir, 4m wide. In summer 1984 the weir crest was lowered for land drainage requirements.
How it measures flow
Low flow gauge, subject to drowning. High flows should be treated with caution. Theoretical rating. The modular limit was reduced when the weir crest was lowered in 1984.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the Blackfoss Beck at Sandhill Bridge flooding today?
The current level is 0.09m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Sandhill Bridge?
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 Blackfoss Beck at Sandhill Bridge?
The typical range at this station is 0.10m to 0.50m, based on Environment Agency historical data. Levels above 0.50m 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.
