💧 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.

3 storm overflows are traced upstream of this gauge, the nearest 530 m away along the river. 0 report discharging now, 3 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 →

How often this river runs high

In a typical year this gauge reaches its typical high of 1.78 m on about 1 day. This year so far: 2 days.

2026 2 days so far
2025 1 day
2024 0 days

Counted from each day's highest reading. Days with missing or implausible readings are left out, so a year marked patchy may have run high more often than shown.

Catchment Character

🌊 Fairly flashy Responds 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.

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

Flat V weir (commissioned Sep 1995), superseded broad-crested weir. Significant baseflow regime but also responsive.

More detail

The catchment

Bewl Water Reservoir constructed 1975, occupies approx. 3% of total catchment area. The River Teise originates to the south east of Tunbridge Wells, and flows east to its confluence with the River Bewl, then north towards the River Medway. Catchment developed on the Wealden Series: comprises Hastings Beds, composed of sandstones, siltstones & clays; Tunbridge Wells Sand, Wadhurst Clay, Ashdown Sand; one quarter impervious, three quarters pervious. The more permeable components are locally important aquifers feeding the numerous springs which provide the baseflow for the headwaters. Catchment is predominantly rural.

The station

Flat V weir 7m wide, located 50 m d/s of a minor road bridge between Horsmonden and Brandfold, in a relatively straight approach. Station used as control point for Bewl Water Reservoir (offtake is ~1km upstream), data inspected regularly by Southern Water. Superseded broad-crested weir (crest width: 5.95m; weir capacity: ~3 cumecs) in trapezoidal section.

How it measures flow

Weed growth can cause problems and no high flow gaugings pre-1995. Crest tapping no longer used. Cableway at site - calibration now extends throughout the flow range (but less reliable above bankfull); gauging of 54 cumecs after Oct 2000 peak. Two peak flow ratings applied across period of record, the most recent is valid from September-1995 when new structure installed necessitating a rating change. Pre-1995 rating valid to bankfull. Post-1995 rating derived from hydraulic modelling and well calibrated to bankfull.

Flow regime

Significant baseflow but also responsive. Augmentation (from Bewl Water) dominates post-1975 low flow patterns; e.g. 1989/90. Runoff influenced by public water supply abstraction and effluent returns. Some artificial regulation from Hope Mill Sluice approx. 3.2km upstream.

The flow record

Missing flows July 1994 - August 1995 during construction of new structure. Isolated and anomalous low flows (e.g. 2004) reflect influence of abstractions for Bewl Water. GDF minimum (0.033 cumecs on 16/02/2005) resulted from significant upstream abstraction. POT and AMAX are pre- and post- Bewl Bridge Reservoir (1975), pre-reservoir rejected. Full period of record peak flow data reviewed and released in September 2023 (WINFAP Files v12).

Frequently asked questions

Is the River Teise at Stonebridge flooding today?

The current level is 0.30m, which is within the typical range of 0.08 to 1.78m. Flooding is unlikely at this level.

Is the river level rising or falling at Stonebridge?

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 Teise at Stonebridge?

The typical range at this station is 0.08m to 1.78m, based on Environment Agency historical data. Levels above 1.78m 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.
