Quick pick:
You'll be notified when this gauge is rising more than 0.10 mASD/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.

Flood predictions aren't generated for
lock / structure gauges —
their levels are driven by gate operation,
not by catchment rainfall, so the forecast models would have no skill here.
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.
Downstream level
7 days
The level on the DOWNSTREAM side of this lock/weir structure — a separate EA
measure from the main (upstream) reading shown on the Current tab. Threshold bands
are computed from this gauge's own downstream history.

Flood history near this gauge
Official Environment Agency warnings issued since 2009 for the 9 flood
areas linked to this gauge (nearest 0.3 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.

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
🌊 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).

More detail
The catchment
Pervious (Chalk) headwaters, mainly London Clay in lowest reaches. Land use mainly agricultural but the Pincey Brook drains Stansted Airport and Hatfield Forest.
The station
Flat V weir (1:10.9 cross-slope) 4.02m wide. Removed from peak flows dataset in September 2023 (WINFAP Files v12).
How it measures flow
Bypassing occurs at high flows (e.g. Oct 2001 flood). Flows > 17 cumecs exceed the capacity of the structure. At tail recorder was added in February 2011, to account for issues with non-modular flow. Non-modularity may have been increasing during the period of record. Flows derived from standard Flat V calculation. Rating is accurate, though more gauging is required to validate high flow range (no current meter readings above 0.6m). All flow is within bank, but by-passing does occur during floods.
Flow regime
Flows reduced by public water supply abstraction. Spray irrigation can be significant (especially in the upper part of the catchment). Balancing ponds at Stansted Airport provide some headwater regulation.
The flow record
Data for period of record re-processed to correct for non-modularity. In the peak flow data, this correction has only been applied for 1982 onwards. For the daily flow data relevant modern levels of non-modularity were utilised to derive reprocessed flows.

Frequently asked questions
Is the Pincey Brook at Sheering Hall flooding today?
The current level is 0.06m, which is below the typical range. Flooding is very unlikely at this level.
Is the river level rising or falling at Sheering Hall?
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 Pincey Brook at Sheering Hall?
The typical range at this station is 0.08m to 1.47m, based on Environment Agency historical data. Levels above 1.47m 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.
