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.

Flood history near this gauge
Official Environment Agency warnings issued since 2011 for the 2 flood
areas linked to this gauge (nearest 4.6 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.
See also the Tideford flood history.
Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
Catchment Character
🌊 Mixed responseA 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).

Photos
Gauging-station photographs from the National River Flow Archive (UKCEH).
Elongated, linear, natural catchment. Headwaters rise from southernmost outcrop of Bodmin granite. Great bulk of the catchment on Devonian shales and slates interspersed with tuffs and lavas. Moderate relief. Land use is agricultural, dairy and mixed farming rough grazing. Some forestry. No major changes to catchment.
The station
Station opened in 1969 with a Crump profile weir, 5.5 m wide and wing walls 2.3m high with subsidiary floodbanks.
How it measures flow
Weir fully modular when flow within flood banks. High flows gauged at road bridge. No bypassing. Rated by gaugings below 0.1m stage, theoretical rating above this. Few gaugings at low flows. Good site and record. All flows contained to date but analysis of tailwater levels post November 2012 flood (biggest on record) showed weir non-modular during event. High flows gauged off road bridge in the past and with ADCP on ropes now. Ratings based on theoretical Crump weir equation. Adjustment for drowning has been applied to the top end based on the findings of the December 2012 event. Extrapolation beyond max gauging at 6.5 m3/s reasonable as flows contained and drowning considered. Two peak flow ratings across period of record.
Flow regime
Natural to within 10% at Q95.

Frequently asked questions
Is the River Tiddy at Tideford flooding today?
The current level is 0.04m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Tideford?
Based on the most recent readings, the level is currently steady. The chart above shows the last 7 days of measurements, updated roughly every 15 minutes.
What is a normal level for the River Tiddy at Tideford?
The typical range at this station is 0.06m 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 taken by the Environment Agency gauge roughly every 15 minutes and FloodRadar refreshes its data continuously, so the level shown is normally less than an hour old.
