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.

Tamarstone Bridge (47174) — flow at this site
7 days
A separate gauge 12.1 m from this one at the same site, shown here for context.
Its readings are its own and are never merged with this page's.
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. Those nearby are listed below.
Nearby, connection not known
Within 6 km in a straight line, but the river map cannot say whether their water passes this gauge.
South West Water · into Trib River Deer (S) · 6.0 km away in a straight line · no mapped watercourse close enough to be sure

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 2008 for the 8 flood
areas linked to this gauge (nearest 5.4 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.
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).
Most of the rocks in the Tamar catchment are hard mudstones, shales, siltstones, sandstones and minor limestones. A major mountain building event during the Carboniferous Period intensely folded the strata which resulted in extensive fissuring and faulting. The flow duration curve for the catchment is relatively steep through its length because the underlying granite, slate and shale restrict groundwater storage whilst slowly permeable soils in the upper catchment promote rapid surface water runoff. No major catchment changes.
The station
Open channel flood warning gauged installed just upstream of road bridge. Station closed 01/10/2017 and converted to level only site for flood warning.
How it measures flow
ADVP flow gauge installed to assist in flow calculation at site. As site is subject to backwatering from downstream this is used to calculate high flows above a stage of around 1 m, approx 3 m3/s. Flow calculations are made via a combination of a low flow rating and data from the ADVP at higher levels. One peak flow rating across the period of record.
Flow regime
The catchment is predominately rural. Tamar Lakes are found in the catchment. The Upper Lake is a water supply reservoir whilst the Lower Lake is no longer used as a reservoir and so acts as an online pond.
Timing, not cause. Gauges can move together simply because the same rain fell on both.
Frequently asked questions
Is the River Tamar at Tamarstone Bridge flooding today?
The current level is 0.27m, which is within the typical range of 0.06 to 1.80m. Flooding is unlikely at this level.
Is the river level rising or falling at Tamarstone Bridge?
Based on the most recent readings, the level is currently rising. 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 Tamar at Tamarstone Bridge?
The typical range at this station is 0.06m 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.
