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.
Get notified when recent rainfall near this gauge crosses its learnt rise trigger — an early "watch"
signal, typically hours before a rise. Experimental; not an official flood warning.

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.

None of the storm overflows FloodRadar holds is traced upstream of this gauge on the mapped river network. That is not the same as none: the map leaves out many small streams and culverts, so an overflow it cannot place may still drain here, and not every company publishes every overflow.
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 →

Flood history near this gauge
Official Environment Agency warnings issued since 2023 for the 1 flood
area linked to this gauge (nearest 3.6 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.

🌊 Steep & flashySteep catchment sheds rain quickly — expect fast, sharp rises after heavy rain.
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.
The physical character of the land that drains to this gauge, and how it shapes its flood response — from the National River Flow Archive (UKCEH).

About this gauge
Concrete flat-V weir in a steep, remote Pennine catchment.
More detail
The catchment
Wet, steep, remote catchment in the Pennines developed mainly on Carboniferous Limestone; some Millstone Grit on south-east boundary. Land use is mostly rough grazing. A habitat restoration project affecting a large proportion of the catchment began in 2023.
The station
Concrete flat-V weir replaced (in 1985) a limited capacity, wooden trapezoidal flume (installed late-1960s); structurefull now 0.95m.
How it measures flow
Bypassing now less common but still overtops structure several times per year. Also goes non-modular.
Flow regime
Flashy, natural regime. Systematic underestimation of rainfall (catch of ground-flush gauge exceeded standard raingauge by >10%) may contribute to unrealistic 'loss'. Also possibility of minor increase in runoff due to spring water deriving from outside the topographical catchment (see geology).
The flow record
Notable January 1995 peak caused by 80-100mm storm. Flows level off 20/12/10 to 27/12/10 when the river froze, data marked as suspect.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the Snaizeholme Beck at Low Houses flooding today?
The current level is 0.25m, which is within the typical range of 0.07 to 0.60m. Flooding is unlikely at this level.
Is the river level rising or falling at Low Houses?
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.
What is a normal level for the Snaizeholme Beck at Low Houses?
The typical range at this station is 0.07m to 0.60m, based on Environment Agency historical data. Levels above 0.60m 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.
