💧 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.

4 storm overflows are traced upstream of this gauge, the nearest 4.2 km away along the river. 0 report discharging now, 4 report not discharging.

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 →

Catchment Character

🌊 Mixed response A 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.

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

Broad crested weir built in 1988 to replace previous velocity area station.

More detail

The catchment

Mixed geology, mostly Upper Devonian, Culm Measures, Carboniferous with some areas of slate and thin limestone. Land-use: rural, low intensity agriculture, beef/sheep and dairy farms in lower reaches. No major urbanisation in the catchment. No major catchment changes.

The station

Velocity area station with a low flow bed control built in 1976. Station re-opened with broad-crested weir in 1988. Channel approximately 9.5m wide.

How it measures flow

Bankfull at 1.8m. Station subject to mobile bed/shoaling downstream of weir so rating prone to shifting. Gaugings taken to allow preparation of ratings to account for this. Multiple peak flow ratings applied across period of record. Rating derived from current meter gaugings from cableway.

Flow regime

No major artificial influences.

The flow record

Station closed 01/01/1981 - 11/10/1988; no data available. Downstream siltation led to the drowning of the control structure during high flows in 12/1999. Full period of record peak flow data reviewed and released in October 2018 (WINFAP Files v7).

What is a normal level for the River Inny at Bealsmill?

The typical range at this station is 0.29m to 1.80m, based on Environment Agency historical data. Levels above 1.80m 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.
